The Biography of Banking: From Ancient Ledgers to the Global Financial System

The First Recorded Banking Activities: Debt Came Before the Bank

There is no single, uncontested “first bank.” Banking began as a collection of functions long before institutions used that name.

In ancient Mesopotamia, temples, palaces and merchant households stored grain and valuables, extended credit and recorded obligations on clay tablets. The critical invention was not a marble banking hall; it was the reliable record of who owed what, to whom, on what terms and by what date. Credit and accounting could therefore exist even when coins were absent or scarce.

Greek and Roman societies added money changing, deposit taking, lending and public finance. Medieval trade then required a safer alternative to transporting metal over dangerous distances. Merchant networks developed transferable claims and bills of exchange: a trader could deliver funds in one city and receive payment in another currency elsewhere.

Renaissance Italian banking houses combined bookkeeping, foreign exchange, trade finance and sovereign lending. The word bank is commonly associated with the Italian banca—the bench or counter from which money changers operated—but the institution was already much more than a physical counter. It had become a network of trust, information and enforceable claims.

Did the Knights Templar Invent the Cheque?

The Knights Templar are frequently credited with inventing the cheque, but that description goes too far. Their real contribution was the development and large-scale use of a trusted international custody and credit network during the 12th and 13th centuries.

A pilgrim, crusader or noble could place money, valuables or property under Templar control and receive documentary evidence of the value. Funds or an equivalent amount could later be made available through another Templar house, reducing the need to carry gold across dangerous territory. In economic function, this resembled a combination of a letter of credit, remittance service and traveller’s cheque. Research into Templar financial activity describes their letters of credit as an important precursor of modern banking.

However, the Templars were not the first civilisation to use written payment orders or transferable claims. Cheque-like instruments—including the sakk—were already used across the medieval Islamic commercial world. A documented 10th-century example discussed in The Journal of African History arose from trans-Saharan trade, well before the Templar network reached its height. Related forms of payment instruction, bills of exchange and remittance also appeared in earlier Indian, Roman and Chinese commerce.

The modern cheque developed later as a written instruction directing a banker to pay a specified amount from a customer’s account. The earliest cheque in the Bank of England Museum’s collection, dated 1660, instructs London banker William Morris to pay £200 to a third party.

The accurate conclusion is therefore that the Templars did not invent the cheque itself. They helped demonstrate the power of a geographically distributed financial network in which identity, records and institutional trust could move value without the physical money making the same journey. That principle survives in correspondent banking, international payments, travellers’ cheques and electronic money transfers.

Merchants, Goldsmiths and the Rise of the City of London

London’s financial development accelerated through commerce. Merchant guilds, shipping, insurance, foreign-exchange dealing and the financing of the Crown gathered within the Square Mile. Sir Thomas Gresham’s Royal Exchange provided a recognised centre for merchants and financiers in the late 16th century.

During the 17th century, London goldsmiths accepted gold and silver for safekeeping, issued receipts against deposits and lent part of those balances. The Bank of England’s historical account describes these goldsmiths as early bankers in Britain. Their receipts helped turn a claim on stored metal into a transferable means of payment.

The weakness of relying on private financiers alone became clear when the Crown defaulted on obligations. In 1694, the Bank of England was established as a privately owned bank and banker to the Government, principally to help finance war with France. Subscribers provided £1.2 million to the state, and the Bank received a royal charter. The institution linked three elements that would shape modern finance:

• government borrowing;
• a bank-supported market in public debt; and
• bank liabilities that could circulate as money.

The Bank did not instantly become a central bank in the modern sense. Its public role accumulated over time. The Bank Charter Act of 1844 strengthened its position in note issuance, while successive crises helped establish the lender-of-last-resort function.

Banking, Corporations and the British Empire

Britain’s commercial and imperial expansion transformed London from a national centre into a global clearing house. Chartered trading companies combined private capital with privileges granted by the state. Merchant banks financed cargoes, insured voyages, discounted bills, exchanged currencies and placed sovereign or colonial bonds with investors.

The system worked through relationships rather than instant communications. A bill accepted by a respected London house carried its credit standing with it. This allowed trade claims originating thousands of miles away to be converted into finance in London. Sterling, the Royal Navy, British commercial law, imperial trade routes and the London capital market reinforced one another.

British overseas banks established branches across Asia, Africa, the Caribbean, Australasia and Latin America. They financed commodities, infrastructure, governments and international trade. Research from the London School of Economics describes how British banks gained long-lasting advantages in colonial financial markets through branch networks, information and institutional support.

This history was not economically or morally neutral. The same machinery that reduced the cost of trade also financed imperial control, extraction and unequal relationships. London banking and merchant firms were connected to plantation economies and the administration of slavery-compensation payments after abolition. Bank of England research documents how London agents and firms converted compensation awards into cash and securities.

The balanced conclusion is therefore not that banking caused every feature of empire, or that it was merely an innocent utility. Banking was an enabling technology of power. It could finance productive infrastructure and international trade, but it could also finance conquest, monopoly and extraction. The allocation of credit has always shaped which activities expand and who benefits from them.

From Government Banker to Central Bank

As national banking systems grew, they needed an anchor: an institution whose money could settle obligations between private banks and whose balance sheet could provide liquidity during a panic. Central banks gradually assumed this role.

Modern central banks commonly perform some combination of the following:

• issue physical currency and central-bank reserves;
• set or implement monetary policy;
• provide the final settlement asset for interbank payments;
• act as banker to the government;
• supply liquidity against eligible collateral;
• supervise banks or support prudential regulators;
• oversee payment, clearing and settlement infrastructure; and
• protect monetary and financial stability.

This produces a two-tier monetary system. The central bank creates the ultimate settlement asset—cash and reserves—while commercial banks create deposit money for their customers. According to the Bank of England, most money in a modern economy is created when commercial banks make loans, simultaneously generating a deposit.

A central bank therefore does not normally decide every loan. It changes the price and availability of liquidity, establishes the regulatory perimeter and influences the conditions under which private banks create credit. This is why monetary policy works through bank funding costs, deposit rates, lending standards, market yields, collateral values and expectations—not through a single mechanical switch.

High-Street, Corporate, Merchant and Investment Banks

The word “bank” now describes institutions with very different customers, balance sheets and risks.

What Does a Merchant Bank Do Today?

The merchant bank has not disappeared; its functions have been redistributed. Historically, merchant houses financed trade, governments and commercial ventures with the partners’ capital, market knowledge and international relationships. Today, “merchant bank” usually describes a relationship-led corporate-finance house or a specialised division rather than a high-street bank with branches, current accounts and payment cards.

Its modern role commonly includes:

• Strategic advice: mergers and acquisitions, disposals, succession, restructuring, capital structure and major transactions involving corporations, governments or family-controlled businesses.
• Private capital: investing the firm’s own money alongside clients and institutions through private equity, growth capital, infrastructure, real assets or direct lending.
• Negotiated finance: arranging private placements, acquisition finance and other long-term funding when a public bond or share offering may be unsuitable.
• Entrepreneurial and family wealth: helping owners manage the connection between a company, a sale or inheritance and the family’s long-term investment capital.
• Specialist trade, export or project finance: retained by some firms as a direct descendant of the old merchant-finance tradition.

The boundary is imperfect. A commercial bank mainly takes deposits, makes loans and earns an interest margin. An investment bank mainly advises, underwrites, distributes and trades securities for fees and dealing income. A modern merchant bank emphasises confidential advice, patient principal capital and long-duration relationships. A large financial group may perform all three roles through separate regulated entities.

Historic merchant-banking names demonstrate how the model evolved. Rothschild & Co now organises its work around Global Advisory, Wealth and Asset Management, and Five Arrows, an alternative-assets business that invests the firm’s capital alongside institutional and private investors. Lazard describes a two-part model of financial advisory and asset management, while its advisory bankers work on mergers, restructuring and capital raising. These are not identical institutions, but both show how the old merchant-bank relationship has survived inside modern advisory and investment businesses.

In the United States, the term also has a narrower regulatory meaning. The Federal Reserve’s merchant-banking investment rules allow qualifying financial holding companies—not their deposit-taking banks—to acquire certain ownership interests as part of bona fide underwriting, merchant-banking or investment-banking activity, subject to conditions. In that context, “merchant banking” resembles regulated principal or private-equity investment more than ordinary banking.

Investment Bank, GIB and G-SIB: Three Different Ideas

These terms are often used as if they describe three levels of the same hierarchy. They do not. Investment bank describes a financial business; GIB is industry shorthand for a globally integrated banking model; and G-SIB is an official regulatory designation based on the consequences that a bank’s failure could have for the global system.

The Role of the Investment Bank

The investment bank is the bridge between issuers, investors and traded markets. It helps a company or government decide how to raise money; values and structures the transaction; finds buyers; underwrites or distributes shares and bonds; and then supports secondary-market liquidity. It also advises on mergers, acquisitions, disposals and restructuring, while its markets division provides execution, hedging, financing and risk transfer to institutional clients.

Its influence extends beyond an individual transaction. By deciding which securities it will underwrite, how they are priced, which investors receive allocations and how much balance-sheet capacity it will commit, an investment bank helps determine where market liquidity forms. Goldman Sachs is probably the clearest global brand associated specifically with investment banking. However, it is no longer a stand-alone partnership in the old sense: the modern Goldman Sachs Group is also a regulated bank holding company and a G-SIB.

The Role of the Globally Integrated Bank

A globally integrated bank expands the investment-bank model into a full international financial network. A multinational client can borrow through the corporate bank, issue bonds through investment banking, hedge currencies through markets, move cash through payments, hold securities through custody and place executives’ or owners’ wealth with the private bank. The value of integration is that the institution can follow the same client across products, currencies, legal entities and financial centres.

J.P. Morgan illustrates the breadth of this model through investment banking, corporate and commercial banking, payments, securities services, markets, asset management and private banking. Citi is another archetype because its banking, markets, services and wealth businesses operate through an unusually extensive cross-border network. Integration gives these banks reach, information and liquidity; it also makes their risk, operational infrastructure and resolution more complex.

The Role of the G-SIB

A G-SIB is not appointed to run the market, nor is “G-SIB” a product sold to customers. The designation recognises a negative externality: some institutions are so large, international, interconnected, complex or difficult to replace that their disorderly failure could transmit losses and operational disruption across borders. The Basel framework measures cross-jurisdictional activity, size, interconnectedness, substitutability and financial infrastructure, and complexity.

The Financial Stability Board’s November 2025 list contains 29 G-SIBs. JPMorgan Chase is alone in bucket 4, carrying a 2.5% additional capital buffer under that list. Bank of America, Citi, HSBC and Industrial and Commercial Bank of China are in bucket 3 at 2.0%. The remaining institutions occupy lower buckets, but all face requirements for additional capital, Total Loss-Absorbing Capacity, group-wide resolution planning and heightened supervision. The next annual list is scheduled for November 2026.

A major banking group may contain several of these businesses, but legal entities, capital, governance and customer assets are not automatically interchangeable. “Under one roof” describes the group’s range of capabilities; it does not mean that every business can freely use every customer’s money.

Offshore Banking and the Eurodollar Market

Offshore banking is a relationship, not merely a tropical location. A transaction is offshore when funds or financial services are booked outside the customer’s home jurisdiction or outside the country that issues the currency concerned. Offshore centres may offer tax neutrality, specialised law, confidentiality, access to international investors or a different regulatory framework. These uses range from ordinary cross-border commerce to regulatory arbitrage, aggressive tax avoidance or the concealment of illicit funds.

London’s most important post-imperial innovation was the Eurodollar market. A Eurodollar is a US-dollar deposit held outside the United States; it has nothing inherently to do with the euro currency. During the 1950s and 1960s, London became the principal centre for dollar deposits and loans booked beyond direct US domestic banking constraints.

The Bank of England’s historical review traces London banks’ role in developing the Eurodollar market from the late 1950s. The City was able to reuse its legal expertise, time zone, correspondent relationships and international dealing culture even as sterling lost its dominant reserve-currency position.

That market helped produce modern wholesale banking: large, internationally mobile deposits funding loans and securities across borders. It also increased interconnectedness. A dollar loan to a borrower in one country might be funded by a deposit from another, booked through a bank in London and hedged in a separate derivatives market.

Regulatory Arbitrage and the Birth of the Offshore Banking Network

The offshore banking network grew because a financial transaction did not have to be legally booked in the same country in which it was negotiated, funded, managed or ultimately invested. Banks that faced reserve requirements, interest-rate ceilings, exchange controls, deposit-insurance costs or other domestic restrictions discovered that foreign branches and offshore affiliates could conduct certain foreign-currency and non-resident business under a different regulatory and tax regime.

The Bank for International Settlements describes the origins of modern offshore banking explicitly as regulatory arbitrage. In the 1960s, large US banks used their London offices to attract dollar deposits beyond US domestic interest-rate ceilings and reserve requirements. London became the centre of the offshore interbank or Eurodollar market, while jurisdictions connected through Britain’s commercial and former imperial networks developed complementary banking, company, trust, insurance and fund structures.

A modern international transaction may consequently involve several legal and operational locations:

• the commercial agreement may be negotiated in London;
• the company, fund or special-purpose vehicle may be incorporated in an offshore jurisdiction;
• the transaction may be denominated and funded in US dollars;
• the governing contract may use English or New York law;
• payments may clear through correspondent banks in London or New York; and
• the proceeds may eventually be invested or distributed in another onshore economy.

This structure is not inherently illegal. Offshore centres are widely used by banks, multinational companies, investment funds, insurers, pension structures, governments and wealthy families. Legitimate purposes include pooling international investors, avoiding multiple layers of taxation on the same transaction, issuing asset-backed securities, managing insurance risk, protecting assets from political instability, arranging cross-border finance and operating in currencies unavailable in a domestic market.

The Same Network Can Conceal Ownership and the Origin of Money

The features that make offshore finance efficient can also make it difficult to police. Shell companies, trusts, nominee directors, professional intermediaries and chains of bank accounts can separate the legal owner of an asset from the individual who ultimately controls or benefits from it.

Money may leave an onshore jurisdiction, pass through several companies or accounts and later return as an apparently foreign loan, investment, consultancy payment or corporate distribution. This is sometimes described as round-tripping. When transactions are deliberately layered to conceal criminal origin or beneficial ownership, the same process can form part of money laundering, tax evasion, sanctions avoidance, corruption or the movement of proceeds belonging to organised criminal and trafficking networks.

Politicians and public officials are not prohibited from holding lawful foreign assets, but their power, access to public funds and exposure to bribery create higher corruption risk. Financial regulation therefore treats many senior officials and their close associates as politically exposed persons, requiring enhanced scrutiny rather than assuming that every offshore holding is improper.

Moving money back through an onshore bank does not automatically make it compliant. A regulated receiving bank must still establish the beneficial owner, source of funds, source of wealth, commercial purpose, tax status and possible sanctions exposure. A transfer can pass technically through the banking system while remaining based on false documentation or concealed criminal proceeds.

The IMF’s assessment of offshore financial centres recognises both sides: offshore structures support legitimate investment, insurance and special-purpose vehicles, but lighter scrutiny and anonymity can also facilitate money laundering and tax evasion. The Financial Action Task Force has consequently strengthened global beneficial-ownership standards intended to prevent criminals, corrupt actors, sanctions evaders and tax evaders from hiding behind companies and trusts.

Central Banks, the BIS, the Rothschilds, IMF and World Bank: Power Without a Single Controller

Central banks, the Bank for International Settlements, the Rothschild banking dynasty, the IMF and the World Bank are often presented as levels within one hidden financial hierarchy. That is historically and institutionally incorrect. They have interacted with governments, currencies and sovereign debt, but they do not have the same owners, mandates or powers.

Central Banks: National Anchors of Money

A central bank is normally created under national or supranational law to perform public-policy functions. Its mandate may include price stability, employment, currency issuance, banking-system liquidity, reserve management, payments, supervision and financial stability. Institutional structures differ—the Federal Reserve System does not look like the Bank of England or European Central Bank—but their policy authority comes from law and the state rather than from an international private banking family.

Central banks sit at the centre of the two-tier monetary system. Commercial banks create most customer deposit money, but they settle obligations using central-bank reserves. Central banks can influence the price and availability of credit, yet they do not directly command every commercial loan, securities trade or government budget.

Independence normally means operational protection from day-to-day political direction, not sovereignty above government or freedom from accountability. Mandates are established through constitutional, treaty or legislative arrangements, while officials report through public institutions.

The Bank for International Settlements

The correct name is the Bank for International Settlements, or BIS. Established in 1930, it is the oldest international financial institution and a principal forum for central-bank cooperation. It provides banking and reserve-management services to central banks, supports research and hosts committees that develop international standards.

The BIS is currently owned by 63 central banks and monetary authorities representing countries responsible for approximately 95% of world GDP. Its capital is held by central banks only. The BIS is therefore best understood as a bank and meeting place for central banks—not a private organisation that owns them.

The failure of Germany’s Bankhaus Herstatt in 1974 exposed the danger created when payments in different time zones did not settle simultaneously. The episode helped prompt the creation of the Basel Committee on Banking Supervision. Today, the BIS hosts work on bank capital and liquidity, payments, markets and financial stability.

Its influence is considerable because central bankers exchange information and develop common frameworks there. However, the BIS does not set one global interest rate, command national central banks or directly supervise every commercial bank. Basel standards must be implemented through national or regional law and regulation.

The Rothschilds: A Prototype International Private-Banking Network

The Rothschilds belong in this biography because their family network demonstrated how information, trust, capital and related banking houses could operate across borders before electronic communications.

Mayer Amschel Rothschild established the family business in Frankfurt, and his five sons developed associated houses in Frankfurt, London, Paris, Vienna and Naples. The structure combined family trust with local market knowledge and rapid correspondence. It allowed the houses to transfer bullion, foreign exchange and government payments across political borders and to place sovereign bonds with an international investor base.

Nathan Mayer Rothschild established the London house, N M Rothschild, in 1809. He became a leading bullion and foreign-exchange dealer, arranged gold for Wellington’s forces and handled British subsidy payments to European allies. Between 1818 and 1835, his London house issued 26 British and foreign government loans.

During the financial panic of 1825, the Rothschild network supplied a large volume of gold when the Bank of England was close to exhausting its coined reserves. This episode illustrates the family’s exceptional strength: branches and agents in several financial centres could mobilise bullion more rapidly than a purely domestic house.

The next generation retained an important role in sovereign and imperial finance. In 1875, N M Rothschild & Sons advanced approximately £4 million to Prime Minister Benjamin Disraeli’s government for the rapid purchase of the Khedive of Egypt’s Suez Canal shares. The transaction connected private banking capacity directly to British geopolitical power.

The family’s historical influence was therefore real and sometimes immense. However, influence over sovereign lending, bullion and bond distribution is not the same as ownership of central banks or international public institutions. There is no documented basis for claims that the Rothschild family owns or secretly controls the BIS, IMF, World Bank or the world’s central banks.

Those claims also flatten a complex history. The various Rothschild branches and present-day firms are not one concealed global command structure. Modern Rothschild businesses participate in advisory, wealth-management, merchant-banking and asset-management markets alongside many competing institutions. Conspiracy narratives frequently replace documented governance with unsupported claims and have often repeated older antisemitic stereotypes about secret Jewish control of money.

The International Monetary Fund

The IMF was conceived by 44 countries at Bretton Woods in July 1944. Its purpose was to promote monetary cooperation and avoid a return to destabilising competitive currency devaluations. Today it monitors economies, provides policy advice, supports capacity development and lends to member countries facing external-financing or balance-of-payments pressures. It lends primarily to countries, not households or ordinary companies.

The IMF is governed by its member countries. Its highest decision-making body is a Board of Governors, with one governor and alternate appointed by each member—normally finance ministers or central-bank governors. Quotas provide financial resources and largely determine voting power, which gives the largest economies greater influence. That weighting can be criticised as unequal, but it is published institutional governance, not private family ownership.

The World Bank

The International Bank for Reconstruction and Development—now part of the World Bank Group—was also created at Bretton Woods. Its first purpose was post-war reconstruction; its role developed toward long-term development, infrastructure, poverty reduction and institutional capacity. Unlike the IMF’s focus on monetary and external stability, the World Bank finances development over longer horizons.

The organisations within the World Bank Group are owned by their member governments and governed through Boards of Governors and Executive Directors. Voting power reflects subscribed shares. The United States is the largest shareholder and has exceptional influence, but the institution is not owned by Wall Street banks, the City of London or the Rothschild family.

How These Institutions Actually Connect

• Central banks own and meet through the BIS, deposit reserves with it and participate in its committees.
• Finance ministers and central-bank governors commonly represent their countries at the IMF and World Bank.
• The IMF may lend to a country facing a currency or external-financing crisis, while the World Bank may finance longer-term development projects.
• Central banks can hold World Bank and other multilateral bonds as reserve assets.
• Private banks can underwrite sovereign or multilateral bonds, advise governments, provide market liquidity and execute foreign-exchange transactions.
• Historically, merchant houses such as Rothschilds performed some cross-border functions that are now shared among investment banks, central banks, multilateral institutions and public debt-management offices.

The connection is therefore a network of mandates, markets and counterparties—not a pyramid with one family or institution at the top.

CLS: From Herstatt Risk to Payment-versus-Payment

Foreign-exchange settlement has a special danger because every trade contains two payments in different currencies. If Bank A delivers the currency it sold before Bank B delivers the currency it bought, Bank A can lose the entire principal—not merely the profit on the trade. Different time zones, correspondent banks and national payment systems once made this exposure unavoidable for many transactions.

What Actually Happened to Bankhaus Herstatt?

Bankhaus Herstatt was not brought down by one foreign-exchange or money-market payment entering the wrong account. The West German bank had accumulated losses from speculative foreign-exchange trading. On 26 June 1974, German supervisors withdrew its licence and ordered it into liquidation at 3:30pm in Frankfurt.

The timing turned a bank failure into an international settlement crisis. Several counterparties had already paid Deutsche marks into Herstatt’s German account. Because New York was still in its morning, the corresponding US-dollar payments had not yet been released. Herstatt’s New York correspondent stopped the outgoing dollars after the closure, leaving those counterparties exposed for the full value of the marks they had delivered. Confidence fell, banks withheld payments from one another and cross-border payment activity seized up.

This became known as Herstatt risk: the danger that one party pays away the currency it sold but never receives the currency it bought. The episode helped bring central banks together through the Basel Committee and, after further public- and private-sector work, led the market toward payment-versus-payment settlement.

How Continuous Linked Settlement Changed FX

In 2002, market participants launched Continuous Linked Settlement. Its core service, CLSSettlement, uses payment-versus-payment, or PvP: one currency leg settles if and only if the corresponding leg also settles. This removes the Herstatt-style principal settlement risk for eligible payment instructions that complete settlement inside CLS.

1. The two parties submit the economic details of their FX transaction, directly or through a third-party service provider.
2. CLS validates and matches the instructions, then calculates each settlement member’s multilateral net funding requirement in every currency.
3. Settlement members make scheduled pay-ins through the relevant national real-time gross settlement systems and their correspondent or nostro arrangements.
4. CLS settles both currency legs simultaneously on its own books. It then makes the corresponding pay-outs.

CLS therefore is not simply an informal private network of banks transferring money among themselves. CLS Bank International is a specialised bank and a systemically important financial-market utility. It maintains an account with the central bank for each of the 18 currencies eligible for CLSSettlement, while central banks cooperate in its oversight through an arrangement administered by the Federal Reserve Bank of New York. Direct settlement members can submit and fund instructions themselves; banks, funds, non-bank financial institutions and multinational companies can obtain indirect access through a settlement member acting as a third-party service provider.

The scale is substantial. CLS reports that CLSSettlement now settles more than US$8 trillion of payment instructions a day in 18 currencies for more than 75 settlement members and over 38,000 other users. Its multilateral netting reduces the funding required by more than 96%, meaning that a member funds its net position rather than every trade gross.

SWIFT Carries Messages; It Does Not Make the Money Final

SWIFT provides secure connectivity and standardised financial messages used by CLS members and their clients. Those messages can carry trade instructions, status information and nostro reporting across institutions and borders. However, SWIFT is the messaging layer, not the settlement asset. Final money movement occurs through CLS, settlement members, correspondent accounts and the relevant central-bank payment systems.

Correct SWIFT details are essential, but they cannot guarantee that no failure will occur. A message can be technically valid yet describe the wrong economic trade, currency, value date, counterparty or beneficiary. Both sides must match; the sender must be authorised; the accounts must be funded; the currencies and trade type must be eligible; sanctions and compliance checks must pass; and every required institution and system must be operational.

What CLS Eliminates—and What It Does Not

CLS is primarily infrastructure for foreign-exchange settlement, not a universal settlement system for every money-market loan, security, repo or correspondent-bank payment. Its success should therefore be stated precisely: CLS has transformed the safety and liquidity efficiency of eligible FX settlement, but it has not made international banking failure-proof.

The continuing gap matters. The BIS analysis of the 2025 Triennial Survey found that only 36% of average daily FX settlement value was settled through PvP, while 10%—more than US$1.4 trillion a day during the survey month—still settled gross on a bilateral basis with full settlement-risk exposure. The system is much safer than in 1974, but Herstatt risk has not disappeared wherever PvP coverage does not reach.

From Sterling to the Dollar: The Empire Fell, but the City Survived

The transfer of financial power from Britain to the United States did not occur in a single moment. It developed through two world wars, the liquidation of British overseas assets, rising external liabilities, the expansion of the American economy and the gradual decline of sterling as the principal currency of global trade and reserves.

Bretton Woods Was a Gold–Dollar Standard

The Bretton Woods system designed in 1944 was not a restoration of the old classical gold standard under which the public could routinely exchange banknotes for gold. It was more accurately a gold–dollar exchange standard. The US dollar was officially convertible into gold for foreign monetary authorities at $35 per ounce, while other participating currencies maintained fixed but adjustable exchange rates against the dollar.

This placed the dollar at the centre of the post-war monetary system and formally recognised the economic power that the United States had accumulated. Gold remained the ultimate official anchor, but dollars became the principal reserve and intervention currency required to operate the system.

The arrangement contained an eventual contradiction: the rest of the world needed an expanding supply of dollars, but the accumulation of claims against the United States ultimately exceeded confidence in America’s ability to convert those dollars into gold at the fixed price. On 15 August 1971, President Richard Nixon suspended official dollar convertibility. The fixed-parity system subsequently gave way to predominantly floating exchange rates.

The dollar nevertheless remained dominant after losing gold convertibility. Deep US capital markets, Treasury securities, trade invoicing, dollar-denominated debt, bank funding and the network effect of global use proved more important than metal backing. In the BIS 2025 foreign-exchange survey, the dollar appeared on one side of 89.2% of all FX transactions.

Britain Finished the War Victorious but Financially Exhausted

Britain’s imperial position had already been weakened by the First World War. The Second World War imposed a still greater cost. Britain sold overseas assets, accumulated debts across the sterling area and became dependent on American supplies. A December 1945 statement to Parliament reported approximately £3.5 billion of external debt against severely constrained gold and dollar reserves.

The United States terminated new Lend-Lease operations immediately after the defeat of Japan in August 1945. This was a profound shock to a British economy still dependent on imported food, fuel and industrial supplies. It did not mean that Washington suddenly demanded cash repayment for everything consumed during the war. Instead, the two countries negotiated a final settlement and the Anglo-American Financial Agreement.

Under the 1945 agreement, the United States extended Britain a total of approximately $4.336 billion through a $3.75 billion line of credit and a further Lend-Lease settlement facility. Repayment was scheduled through annual instalments beginning in 1950, with permitted deferrals, and was ultimately completed in 2006.

The strategic pressure came from more than the debt principal. Britain needed American dollars, and the loan was tied to a new economic order based on currency convertibility and more open trade. The requirement to make sterling convertible in 1947 placed intense pressure on reserves and had to be suspended after only weeks. Sterling was devalued in 1949, and the 1956 Suez Crisis later demonstrated that Britain could no longer act as an autonomous imperial power when its currency and reserves were vulnerable to American financial pressure.

War debts were therefore not the sole cause of the British Empire’s decline, but they were part of the mechanism through which economic leadership passed to the United States. Industrial capacity, military cost, independence movements, decolonisation, lost overseas assets, sterling weakness and the rise of the dollar all contributed.

London Changed Its Currency Without Abandoning Its Network

The remarkable feature of this transition is that the decline of the British Empire did not destroy London as a financial centre. Political control receded and sterling lost monetary supremacy, but the City retained a difficult-to-reproduce concentration of banks, brokers, insurers, lawyers, accountants, shipping specialists, commodity merchants and international relationships.

London then adapted the inherited imperial network to the dollar age. Foreign banks expanded in the City. The Eurodollar market allowed dollar deposits and loans to be arranged outside the United States. London’s time zone bridged Asia and North America, English commercial law remained widely used, and the depth of its foreign-exchange, insurance, shipping, bullion and securities markets continued to attract international business. The 1986 Big Bang later added corporate scale, foreign ownership and electronic dealing.

This creates one of the central paradoxes in financial history:

The British Empire declined, but much of its financial nervous system survived. London ceased to control the dominant global currency, yet became the leading international marketplace in which that new dominant currency could be traded, borrowed, lent and hedged.

How Much of “London” Is the City of London?

The historic core remains the Square Mile, governed by the City of London Corporation and centred on institutions around the Bank of England, the Royal Exchange, Lombard Street, Threadneedle Street and the eastern end of the Embankment. However, the modern London financial centre is geographically broader than the Corporation’s boundary.

Canary Wharf in the London Borough of Tower Hamlets became a major banking and trading district after the Big Bang. Asset managers, private-equity firms and hedge funds also cluster in Mayfair and the West End, while legal, government and professional-service institutions extend through Holborn, the Strand, Westminster and the wider Embankment corridor. These districts form one connected London ecosystem, but they are not all governed by the City of London Corporation.

Is London Still the World’s Main Banking Centre?

London is unquestionably one of the world’s principal financial centres, but “the undisputed number one” would be too absolute because the answer changes by activity and index. The March 2026 Global Financial Centres Index placed New York first and London second, separated by only one rating point. The City of London Corporation’s own comparative study placed London first.

The strongest objective claim concerns wholesale markets. According to the BIS Triennial Central Bank Survey, the United Kingdom remained the world’s leading FX trading location in April 2025, handling approximately 38% of global turnover. It also handled 50% of global over-the-counter interest-rate derivatives turnover.

London therefore remains less the capital of a vanished empire than the operating centre of a living international network. Its continuing power comes not from controlling territories or issuing the dominant currency, but from concentrating counterparties, law, liquidity, information, professional services and market infrastructure in one globally connected location.

London’s 1986 Big Bang: Buyers, Sellers and Jobbers Under One Roof

Before the Big Bang, the London Stock Exchange operated under single capacity. A broker represented investors and routed their orders. A jobber acted as a wholesale market maker, buying and selling securities from its own book and quoting prices to brokers. The separation was intended to limit conflicts between agency and principal trading.

On 27 October 1986, the Big Bang reforms transformed this structure. Fixed minimum commissions disappeared, corporate and foreign ownership expanded, screen-based quotations became central and firms could operate in dual capacity—acting both as agent for clients and principal in the market.

A contemporary Bank of England review described the coming quote-driven, competing-market-maker system and the ability of firms to deal directly with investors or act as agents. Evidence later submitted to the UK Parliamentary Commission on Banking Standards observed that the abolition of single capacity allowed jobbers, brokers and investment banks to merge into integrated banks.

This is the moment most closely matching the description of putting buyers, sellers and jobbers “under one roof.” Large British, US, European and Asian banks acquired old City partnerships. Reuters’ retrospective on the Big Bang’s financial legacy records how firms such as Phillips & Drew became routes for global banks to enter investment banking.

Big Bang also opened the ownership and membership of the London securities market to foreign institutions on an unprecedented scale. Foreign investors had already been able to buy British securities, and overseas banks had operated in London long before 1986. The decisive reform was that a single outside institution could own 100% of a Stock Exchange member firm, replacing the old restrictions on non-member ownership. Foreign banks and securities houses could therefore acquire established brokers or jobbers—or enter directly—and combine dealing, market making, research, underwriting and distribution within a well-capitalised London operation. The Bank of England’s 1987 review recorded that the transformed membership included British and foreign banks and securities houses entering through acquisitions, participations and direct membership.

The effect was not merely that foreign money could buy UK shares; it was that foreign financial companies could buy the City firms that traded, made markets in and distributed those shares. London consequently became a more deeply international operating base for US, European and Asian banks, accelerating the movement from traditional partnerships toward global securities conglomerates.

From the Old City to Global Integrated Banks

The institutional map changed almost as quickly as the trading rules. Old English merchant banks, brokers and jobbers that had once occupied distinct positions in the market were bought, merged or folded into much larger groups. Phillips & Drew went to Union Bank of Switzerland; Morgan Grenfell to Deutsche Bank; S. G. Warburg to Swiss Bank Corporation; Kleinwort Benson to Dresdner Bank; and, after its 1995 collapse, Barings to ING. British banks also assembled their own integrated securities operations: Barclays combined its merchant bank with broker de Zoete & Bevan and jobber Wedd Durlacher to create BZW.

The new order was the globally integrated bank: a group able to combine corporate lending, securities dealing, market making, underwriting, mergers and acquisitions, foreign exchange, derivatives, research, asset management and custody across financial centres. Scale, technology, distribution and balance-sheet capacity replaced the personal capital and specialist function of the old partnership as the dominant competitive advantages.

This corporate consolidation changed the buildings too. Small specialist offices and exchange-floor relationships gave way to vast dealing rooms, resilient telecommunications and computer systems, and buildings with the large open floorplates required by hundreds of traders and support staff. Broadgate, London Bridge City and later Canary Wharf became the physical expression of the new banking model. “Global integrated bank” is a descriptive term here; it should not be confused with G-SIB, the later regulatory designation for a global systemically important bank.

When London Boomed: Japanese Banks, American Investment Houses and the Yuppie City

The rule change produced a visible human and cultural transformation. Japanese banks and securities houses—including Nomura, Daiwa, Nikko and Yamaichi—expanded alongside American institutions such as Merrill Lynch, Citicorp, Goldman Sachs, Bank of America and Chase. They brought capital, international clients, new dealing technology and a willingness to hire aggressively in a market where established British partnerships had often lacked the balance sheets required for global competition.

This Japanese presence did not begin on Big Bang day. Nomura opened a London representative office in 1964, established its London subsidiary in 1981 and became a registered member of the London Stock Exchange in March 1986. Big Bang gave that existing foothold a far larger marketplace. By the end of 1987, the Bank of England described Japanese banks as London’s largest foreign banking group by assets and reported that they accounted for more than 35% of the City’s international banking business. Nomura subsequently became the world’s leading Eurobond underwriter in 1987.

Each working morning supplied the public image of the boom: a river of dark suits leaving London Bridge, Cannon Street, Liverpool Street and Waterloo and flowing toward the Square Mile. The bowler hat belonged more to the older City gentleman and was already becoming uncommon; the new City uniform was more likely to include pinstripes, red braces, a Filofax and, for the most successful, an early mobile phone. Together they became symbols of the yuppie—the young urban professional associated with long hours, performance bonuses, property, consumption and financial ambition.

London’s physical landscape changed with its workforce. Dealing rooms demanded larger, open floors, communications equipment and computer capacity that the old alleyways and partnership offices could not always provide. The London Bridge City redevelopment transformed the former Hay’s Wharf district between 1985 and 1988, while Broadgate and the later development of Canary Wharf extended the financial centre beyond its traditional streets. Historic England links the post-Big Bang influx of foreign investment banks directly to the surge in demand for new office space and the speculative property boom.

For a period, London appeared to have discovered a financial growth machine: foreign capital bought City firms, larger firms hired more people, higher incomes lifted restaurants and property, technology increased trading capacity and greater liquidity attracted still more international business. This was the “golden 1980s” City remembered in popular culture.

But the boom was never a straight line. Black Monday struck in October 1987, only twelve months after Big Bang. The Japanese asset bubble burst at the end of the decade, the UK entered an early-1990s recession and several newly enlarged operations withdrew or consolidated. The lasting achievement was not permanent 1980s exuberance; it was that London had built an international market structure capable of surviving the cycle and attracting the next generation of global banks.

Why Japan’s Financial Boom Collapsed

Japan’s post-war economic rise was real, but it was not a Japanese version of the Marshall Plan. The Marshall Plan rebuilt Western Europe. Japan instead received US occupation-era relief and reconstruction assistance through the GARIOA and EROA programmes, while reforms, access to the US market and the American security umbrella created favourable conditions for recovery. The Korean War then delivered a powerful demand shock: Japan became the principal supply base for United Nations forces. Shipbuilding, steel, automobiles, machinery and, later, semiconductors became pillars of an export economy supported by high domestic saving, industrial policy, imported technology and increasingly capable Japanese firms.

By the late 1980s, Japanese current-account surpluses and capital outflows had made its banks central to international finance. Japanese institutions did not literally own most of the world’s liquidity, but they had replaced US banks as the leading international lenders and played a major role in recycling Japanese savings through London, New York and Asian markets. Their apparent strength was magnified by the yen’s appreciation and by soaring Japanese land and equity values, which supported large balance sheets and cheap expansion.

International pressure was part of the story. The 1984 US–Japan accord accelerated financial liberalisation, and the 1985 Plaza Accord sought a lower dollar against the yen and other major currencies. Japan also faced serious US trade pressure over semiconductors, formalised in the 1986 US–Japan Semiconductor Arrangement. These measures changed competitive conditions, but they did not amount to a coordinated American–European order to withdraw every banking counterparty from Japan.

The immediate bubble mechanism was predominantly domestic. The yen’s rapid rise created fears of recession, and the Bank of Japan cut its official discount rate from 5% in 1985 to 2.5% by February 1987, keeping it there for 27 months. Low rates, financial deregulation, competition for borrowers and lending secured against ever-rising land values fed one another. As large companies raised more money in capital markets, banks pushed further into property and smaller-company lending. Bank of Japan research later found that growth in real-estate lending was the best explanation for differences in banks’ bad-loan ratios.

The turn came when domestic policy tightened. The Bank of Japan began raising rates in May 1989 and took the discount rate to 6% by August 1990. Equity prices fell sharply in 1990; land prices followed. Falling collateral values exposed excessive leverage, weakened bank capital and produced mounting non-performing loans. Delayed recognition and repeated refinancing of impaired borrowers prolonged the damage into the “lost decade.” Japan’s 1990s banking crisis was therefore a domestic balance-sheet crisis operating inside an international financial system—not principally the result of the country becoming unable to find any counterparty.

Foreign liquidity withdrawal still mattered as an amplifier. US and European firms reduced or repriced exposures when Japanese creditworthiness deteriorated, while capital rules and falling share prices constrained Japanese banks themselves. But the retreat was gradual and uneven, not a clean blockade: BIS data show that Japanese banks’ claims on emerging Asia actually doubled between the end of 1990 and mid-1997. In real markets, “no counterparties” usually means higher margins, tougher collateral, shorter maturities and selective refusal—not that every wire and dealing relationship disappears at once.

The institutional reckoning arrived later. In 1997, Hokkaido Takushoku Bank and Yamaichi Securities failed; the Long-Term Credit Bank of Japan and Nippon Credit Bank were nationalised in 1998. The broader lesson is that political pressure and international capital flows can shape a boom, and foreign retrenchment can deepen a bust, while the decisive fragility may still have been created at home through leverage, collateral inflation, weak credit discipline and delayed loss recognition.

The benefits were greater competition, more capital, lower explicit trading costs, wider international access and faster adoption of technology. The costs were equally important: larger balance sheets, more complex conflicts of interest, a more transactional culture and the concentration of several critical market functions inside institutions that could become systemically important.

From Universal Banks to the 2008 Financial Crisis

London’s reforms were part of a broader global movement toward deregulation, consolidation, securitisation and cross-border finance. In the United States, the Glass-Steagall separation of commercial and investment banking was progressively weakened and key restrictions were repealed in 1999. Banking groups expanded securities dealing, derivatives, structured credit and off-balance-sheet vehicles.

The 2007–2009 global financial crisis showed the vulnerability of this model when high leverage, short-term wholesale funding, opaque securities and correlated housing exposure met falling collateral values. Banks were not the only institutions involved, but their payment role, deposit liabilities, credit creation and market connections made disorderly failure economically dangerous.

Post-crisis reforms raised capital and liquidity standards, expanded central clearing, introduced recovery and resolution planning and imposed additional requirements on globally systemically important banks. The Financial Stability Board’s 2025 list identifies 29 global systemically important banks, with higher loss-absorbency requirements according to their systemic importance.

The objective is not to make failure impossible. It is to reduce its probability and make a failing institution resolvable without destroying deposits, payments and market functioning or forcing taxpayers to preserve shareholders.

The Fall of Banks: No Institution Is Too Big to Fall

The phrase “too big to fail” is often misunderstood. It does not mean that a large bank cannot become insolvent, lose its independence or disappear. It means that authorities may judge its uncontrolled collapse too dangerous for deposits, payments, credit and connected markets. They may therefore support a sale, create a bridge bank, guarantee critical liabilities, nationalise the institution or use resolution powers to keep essential functions operating.

The institution can still fail in every commercial sense. Shareholders can be wiped out, executives removed, creditors forced to absorb losses and the historic name erased. What public authorities try to preserve is not necessarily the bank—it is the continuity of money, deposits, payments and credit around it.

How a Run Can Collapse a Bank

A bank promises to return deposits at par and usually on demand, but it invests much of that money in loans and securities that mature later or cannot be sold immediately without a discount. This maturity transformation is economically useful and inherently vulnerable: no ordinary bank keeps enough cash to repay every depositor simultaneously.

1. A trigger creates doubt. It may be a disclosed loss, an asset write-down, fraud, a failed capital raising, a credit-rating downgrade, a rumour or visible trouble at a similar institution.
2. Depositors and wholesale lenders withdraw. Uninsured depositors, money-market funds, other banks and corporate treasurers usually move first because their exposures are large and they can transfer them quickly.
3. The bank consumes its liquid assets. It uses cash and central-bank reserves, pledges collateral for emergency borrowing and sells readily marketable securities.
4. Forced sales crystallise losses. Securities intended to be held to maturity may have fallen in value as interest rates rose. Selling them turns an unrealised accounting loss into a realised capital loss.
5. Confidence feeds on itself. Falling capital, emergency borrowing and reports of outflows convince more depositors and counterparties to leave. Collateral demands rise while ordinary market funding disappears.
6. The bank is sold, supported, resolved or closed. A central bank can bridge a temporary shortage against acceptable collateral; it cannot permanently repair an insolvent balance sheet with liquidity alone.

A liquidity failure means the bank cannot obtain cash quickly enough even though its assets may ultimately cover its liabilities. A solvency failure means the assets are no longer worth enough to repay creditors in full. In practice, the two interact: a solvent bank can be forced into damaging fire sales, while a run can expose an insolvency that accounting values had concealed.

Modern runs are faster than the queues once seen outside branches. Mobile banking moves deposits in seconds, corporate accounts can transfer millions at once and social media can synchronise fear. The Financial Stability Board concluded from the March 2023 turmoil that technology made transfers easier and faster and that social media influenced some runs. The modern queue is digital, continuous and geographically invisible.

Can Short Sellers Bring Down a Bank?

A conventional short seller borrows a bank’s shares, sells them and hopes to repurchase them later at a lower price. That transaction does not remove deposits from the bank and does not directly reduce the regulatory capital already on its balance sheet. A falling share price is therefore not the same thing as cash leaving the institution.

It can nevertheless become part of a destructive feedback loop. A collapsing equity price advertises distrust, makes new equity more expensive or impossible to issue and may alarm depositors, bondholders, derivatives counterparties and rating agencies. Traders may also sell the bank’s bonds or buy credit-default protection, raising the market price of insuring its debt. Counterparties then shorten maturities, demand more collateral or refuse new exposure; depositors leave; and a market signal becomes a funding event.

Short selling is not automatically an attack. It normally adds liquidity, supports hedging and helps prices incorporate bad information. Short sellers have often identified leverage, asset-quality problems or misleading accounts before management admitted them. The lawful seller may therefore be the messenger rather than the cause. The abuse is a “distort-and-short” campaign—taking a negative position and spreading false information—or naked short selling that breaches delivery and anti-fraud rules.

During the 2008 crisis, US and UK regulators temporarily restricted short selling in financial shares because of the link between share prices and institutional confidence. The episode captured the dilemma: suppressing abusive manipulation can interrupt a panic, but suppressing legitimate negative views can also weaken price discovery. The enduring defence is not a permanently protected share price; it is transparent accounts, credible asset values, strong capital, sufficient liquidity and depositors who believe the resolution and insurance framework will work.

Famous Failures, Rescues and Forced Sales

What Actually Happens When a Bank Fails?

1. The problem is identified as liquidity, solvency or both. A sound bank facing a temporary cash shortage may borrow from a central bank against collateral. A bank whose assets are worth less than its obligations needs capital, a sale or resolution—not merely a short loan.
2. Supervisors close, resolve or restructure it. An insured US bank normally enters FDIC receivership. A complex group may use a bridge bank, bail-in, forced merger, nationalisation or insolvency proceedings under the relevant jurisdiction.
3. Deposits and critical operations are protected or transferred. Deposit insurance protects balances up to the legal limit. Authorities often arrange for customers, branches, cards and direct debits to continue through an acquiring or bridge institution.
4. Shareholders absorb losses first. Equity is not deposit insurance. Subordinated instruments and unsecured creditors may then absorb losses according to the creditor hierarchy and applicable resolution law.
5. The loans do not disappear. Borrowers still owe their mortgages and business loans. The receiver, bridge bank or purchaser becomes the new creditor and may retain, restructure or sell those assets.

The US FDIC’s preferred method is a purchase-and-assumption transaction, in which a healthy institution assumes some or all deposits and purchases selected assets. Anything not transferred remains in receivership for later sale or collection. This is why a failed bank can vanish on Friday while many customers continue using accounts under a new name on Monday.

Commercial Property and Regional Banks: The Present Fault Line

Commercial real estate, or CRE, is a particular concern for smaller and regional US banks because relationship lenders hold a larger concentration of local office, retail, hotel, construction and multifamily loans relative to their capital than the largest diversified banks. The risk is not simply that a building becomes empty. Higher interest rates raise refinancing costs, weaker occupancy reduces cash flow, higher capitalisation rates reduce valuations and a maturity can force the new economics to be recognised all at once.

The latest data available at the time of writing do not describe a general banking collapse. The Federal Reserve’s first-quarter 2026 figures show an overall delinquency rate of 1.49% for bank loans and leases and 1.61% for commercial real-estate loans. The FDIC reported that industry capital and liquidity remained strong. However, non-owner-occupied and multifamily CRE performance remained weaker than pre-pandemic norms. An apparently modest national average can conceal serious pressure at an individual bank with a concentrated loan book.

From Delinquency to NPL: Where Does the Loan Go?

A delinquent loan is not automatically a total loss. The path usually develops in stages:

1. The borrower misses payments or appears unlikely to refinance at maturity.
2. The bank increases monitoring, updates cash-flow forecasts and obtains a new collateral valuation.
3. The exposure may be classified as criticised or non-performing and placed on nonaccrual, stopping the bank from recognising unpaid interest as ordinary income.
4. The bank increases its allowance for expected credit losses, reducing earnings and potentially capital.
5. The parties may extend the maturity, obtain additional collateral, inject sponsor equity, reduce principal or restructure the loan onto supportable terms.
6. If recovery is not reasonably expected, the unrecoverable amount is charged off. The bank may foreclose, take the property, appoint a receiver or sell the loan at a discount.

A prudent workout is not necessarily “extend and pretend.” If a viable property can service reasonably modified terms, restructuring can preserve more value than a forced sale. But rolling an uneconomic loan merely to avoid recognising a loss delays the adjustment and can weaken confidence in the bank’s accounts.

Will REITs or Larger Banks Absorb the Loan Books?

Some will—but there is no single buyer waiting to absorb every bad loan.

• Healthy banks may acquire deposits, branches and selected performing loans through an FDIC transaction or negotiated portfolio sale. They will price expected losses and may reject the weakest assets. Regulators may also resist a transaction that merely transfers an excessive CRE concentration to another regional bank.
• Mortgage REITs may buy mortgages, loan participations or commercial mortgage-backed securities when the yield compensates for credit and funding risk.
• Equity REITs normally own properties rather than bank loan books. They may purchase foreclosed buildings or recapitalise assets that fit their specialist sectors.
• Private-credit, opportunity and distressed-debt funds can buy whole loans or portfolios at discounts, provide rescue capital or take control through a restructuring.
• Special servicers and receivers work out securitised loans, enforce collateral and sell properties or claims over time.

The likely outcome is therefore a mixture of bank consolidation, private-capital purchases, restructurings, foreclosures and gradual loss recognition. The loan moves, but the economic loss does not evaporate: it is allocated among the original bank, its shareholders and creditors, the borrower, the deposit-insurance fund, the buyer and—in exceptional systemic interventions—the public balance sheet.

What Role Do Banks Have in Today’s Market?

Banks remain the bridge between the real economy, money and capital markets. Their modern role can be understood through ten connected functions.

1. They create deposit money through credit

When a commercial bank approves a loan, it normally creates a corresponding deposit. Lending therefore expands purchasing power, subject to capital, liquidity, risk, funding demand and monetary-policy constraints. Repayment extinguishes the associated deposit money.

2. They transmit central-bank policy

A policy-rate decision reaches the economy through overnight markets, bank funding, deposit competition, mortgage and corporate lending rates, bond yields, exchange rates and asset valuations. If banks tighten lending standards despite lower official rates, transmission may be weak. If credit expands aggressively, policy may transmit more strongly than expected.

3. They operate the payment network

Cards and banking apps are the visible layer. Beneath them sit deposit accounts, correspondent banks, messaging systems, clearing houses, collateral and final settlement in central-bank money. A payment may appear instant to a customer while several institutions manage settlement and counterparty risk behind the screen.

4. They finance households, companies and governments

Banks fund mortgages, inventories, payrolls, machinery, mergers, trade and public deficits. They may retain loans on their balance sheets, syndicate them to other lenders or transform them into securities. This determines where credit is available and at what price.

5. They connect issuers with investors

Investment banks advise issuers, structure transactions, underwrite shares and bonds, build order books and distribute securities. A company’s access to public capital is therefore not simply a meeting with “the market”; banks often organise the meeting.

6. They make markets and provide liquidity

Dealer banks quote bid and offer prices in government bonds, corporate debt, currencies and derivatives. They may temporarily hold inventory when buyers and sellers do not arrive simultaneously. Their willingness and balance-sheet capacity can determine whether a large trade moves price by one basis point or many.

7. They enable risk transfer

Companies, asset managers and governments use bank-intermediated forwards, swaps and options to manage interest-rate, foreign-exchange, commodity and credit risk. The hedge removes risk from one balance sheet but does not erase it; the exposure is transferred, netted, collateralised or offset elsewhere.

8. They hold, finance and service assets

Custody banks safeguard securities and process income, corporate actions and settlement. Prime brokers finance hedge-fund positions, lend securities and consolidate trading services. Repo desks turn high-quality securities into short-term funding. These functions are largely invisible until they stop working.

9. They connect national systems

Correspondent banking and global dealer networks connect currencies and jurisdictions. This supports trade and investment but creates chains of fees, compliance checks, timing differences and counterparty exposures. BIS-led projects are now exploring shared programmable infrastructure for faster cross-border settlement, while preserving central-bank money as the anchor.

10. They absorb risk—and can amplify it

A well-capitalised bank evaluates borrowers, absorbs expected credit losses and diversifies risk. A weak or overleveraged bank can do the opposite: withdraw credit, sell assets, call collateral and transmit stress across markets. Banks are shock absorbers when resilient and shock amplifiers when confidence in their funding or assets collapses.

Who Controls the Global Banking System?

No single institution controls it.

• National central banks anchor currencies, reserves, liquidity and monetary policy.
• Commercial banks create deposit money and allocate credit.
• Investment banks and broker-dealers connect issuers, investors and traded markets.
• National regulators and resolution authorities license, supervise and, when necessary, restructure institutions.
• The BIS and Basel committees coordinate central banks and develop international standards.
• The IMF monitors the international monetary system and supports countries under external stress.
• The World Bank and development institutions provide long-term development finance.
• Exchanges, central counterparties, custodians and settlement systems provide market infrastructure.
• Asset managers, pension funds, insurers, hedge funds and private-credit funds increasingly determine the demand for securities and the supply of non-bank finance.

The system is therefore governed by overlapping public mandates and private balance sheets. It is decentralised in decision-making but highly concentrated at key points of settlement, custody, clearing, market making and dollar funding.

Financial Hegemony and the Weaponisation of Banking Networks

Financial hegemony does not require one institution to control every payment. It arises when one currency, legal jurisdiction and connected group of infrastructures become so central that access to them is necessary for ordinary international business. The US dollar’s role in trade invoicing, reserves, debt, foreign exchange and bank funding gives the United States exceptional reach. London and the European Union add major centres of banking, custody, insurance and financial messaging, while American card companies provide globally recognised consumer-payment networks.

“Weaponisation” is the political description applied when governments use those financial connections to pursue foreign-policy or national-security objectives. The legal instruments are sanctions, asset freezes, transaction bans, export controls and restrictions on correspondent accounts. They may be directed at war finance, terrorism, organised crime, proliferation or sanctions evasion. From the target country’s perspective, however, the effect is the same strategic warning: dependence on a foreign-controlled financial gateway can become a vulnerability during conflict.

Was Russia Banned from SWIFT?

Not as an entire country in one operation. On 2 March 2022, the European Union ordered seven named Russian banks—Bank Otkritie, Novikombank, Promsvyazbank, Bank Rossiya, Sovcombank, VEB and VTB—to be excluded from SWIFT. Further banks and majority-owned subsidiaries were added in later sanctions rounds. The restrictions were progressively widened, and in July 2025 the EU converted the existing messaging prohibition affecting listed banks into a broader transaction ban and added more institutions.

SWIFT implemented these measures because it is incorporated in Belgium and must comply with EU law. It did not independently “ban Russia.” SWIFT is not a bank, does not hold customer accounts or funds and does not settle the underlying payment; it carries standardised messages. Removing that messaging route is nevertheless powerful because banks must find slower bilateral instructions or other networks, while separate sanctions may prohibit correspondent banks from executing the payment at all.

Russian domestic payments did not stop. Russia had already built a domestic card switch, the Mir card system and the Central Bank of Russia’s System for Transfer of Financial Messages, or SPFS. When Visa and Mastercard suspended Russian operations in March 2022, Russian-issued cards lost their international network use and foreign-issued cards stopped working in Russia, but eligible domestic card transactions could continue through Russia’s national infrastructure. This shows the difference between disconnecting an international network and abolishing payments inside a country.

Why This Has Encouraged BRICS and Other Alternatives

The sanctions on Iran and Russia demonstrated that access to reserves, correspondent accounts, card networks and messaging can be restricted during a geopolitical confrontation. That experience strengthened an existing desire among BRICS governments and other emerging economies to reduce single-network dependence, settle more trade in national currencies, hold more gold and non-dollar reserves and build payment systems that remain available during a dispute with Western governments.

The response is real but often exaggerated. The 2024 Kazan Declaration supported stronger correspondent-banking links within BRICS and the voluntary, non-binding BRICS Cross-Border Payments Initiative. It also called for further study of a possible BRICS Clear cross-border settlement and depositary infrastructure. The New Development Bank set a target for 30% of its 2022–2026 financing to be in members’ local currencies. China has CIPS for renminbi payments; Russia operates SPFS; and several countries are linking instant-payment and central-bank digital-currency experiments.

These projects do not yet constitute a single BRICS currency, a unified BRICS central bank or a complete replacement for SWIFT and the dollar system. Brazil’s 2025 BRICS presidency explicitly distinguished cheaper trade in local currencies from creating a new common currency. The New Development Bank itself continues to borrow in dollars as well as renminbi, rand and other currencies. Diversification and coexistence are much further advanced than outright replacement.

The long-term result may be a more multipolar but also more fragmented financial system. Alternative rails can improve resilience and competition; incompatible standards, smaller liquidity pools and divided compliance regimes can increase cost and risk. IMF research finds that sanctions have encouraged modest reserve shifts toward assets such as domestically stored gold, but the dollar’s decline in reported reserves remains gradual rather than a sudden collapse. Its advantage still rests on deep markets, abundant safe assets, convertibility, legal infrastructure and network effects that cannot be reproduced simply by political declaration.

The paradox of financial power is therefore strategic: using a dominant network makes sanctions effective today, but every use gives targeted and non-aligned countries another reason to reduce their dependence on that network tomorrow.

The Rise of Non-Banks Does Not Make Banks Irrelevant

Modern finance is shifting toward market-based and non-bank intermediation. ETFs, mutual funds, pensions, insurers, hedge funds, sovereign wealth funds and private-credit managers now hold and allocate enormous pools of capital. The BIS reports that non-bank financial institutions’ assets increased substantially relative to global GDP after the financial crisis.

Yet non-banks frequently remain connected to banks through credit lines, subscription facilities, deposits, derivatives, repo, foreign-exchange hedges, custody and prime brokerage. Risk can migrate out of the regulated banking book without leaving the banking network.

This is one of today’s central stability questions. The IMF’s April 2026 Global Financial Stability Report highlights cross-border interconnectedness between banks and non-banks as a medium-term vulnerability. Reuters has also reported growing regulatory attention to banks’ exposure to private credit.

The next crisis may not begin with a conventional run on high-street deposits. It could begin in leveraged sovereign-bond trades, private credit, a clearing house, a cyber event, a stablecoin or a liquidity mismatch in a fund—and still reach banks through funding, collateral and derivatives.

The End of the High-Street Bank? CBDCs, Tokenisation and the Bank Without a Branch

The traditional high-street branch is declining, but that is not the same as the end of banking. Mobile apps, instant payments, remote identification, open-banking interfaces and automated service have moved routine activity away from physical counters. Maintaining duplicate branch networks becomes difficult when most customers check balances, transfer money and apply for products online.

Branches will probably continue to consolidate into fewer full-service sites, shared banking hubs, cash facilities and specialist centres for mortgages, business banking, fraud, bereavement and customers who need face-to-face or accessibility support. UK rules do not prevent closures, but designated banks must assess and fill significant local gaps in cash access before affected facilities disappear.

A Digital Pound Is Not Yet a Fact

A retail central-bank digital currency, or CBDC, would be an electronic claim on the central bank available to households and businesses—closer in credit quality to digital cash than to a commercial-bank deposit or unbacked cryptocurrency. As of the Bank of England’s March 2026 update, no decision has been made to introduce a digital pound. The work remains a design and policy exercise.

If households could move unlimited deposits into central-bank money instantly, particularly during a panic, commercial banks could lose an important source of funding. That is why leading CBDC designs consider holding limits, no interest on balances and distribution through regulated banks or payment providers. The European Central Bank has similarly designed the proposed digital euro so that supervised intermediaries remain the customer interface and holdings do not become an unlimited substitute for bank deposits.

Tokenised Central-Bank Money Is Not the Same as Retail CBDC

Tokenisation means representing money or another asset on a programmable platform where ownership, compliance logic and settlement can interact. Wholesale tokenised central-bank reserves would be used among eligible financial institutions; tokenised commercial-bank deposits would remain claims on private banks; a retail CBDC would be central-bank money available for everyday public use. Stablecoins are another category again: privately issued digital claims whose safety depends on their assets, redemption arrangements, governance and regulation.

The future may therefore modernise the existing two-tier banking system rather than replace it. The BIS and central-bank Project Agorá demonstrated a prototype combining tokenised commercial-bank deposits with tokenised central-bank reserves for atomic multi-currency settlement. Instead of one party sending money and waiting for a separate process to complete, related payment, compliance and settlement conditions can be executed together.

What Disappears—and What Survives?

The strongest conclusion is therefore not “the end of the bank,” but the separation of banking from the bank building. Technology can transform the interface and settlement rail. It does not remove the need to decide who receives credit, who absorbs a default, whose liability counts as money and who restores confidence when everyone wants repayment at once.

Why Banks Matter to Traders and Investors

A trader does not need to own a bank stock to be trading the banking system.

• Equity indices: bank lending and dealer risk appetite influence economic growth, buybacks, issuance and valuation.
• Government bonds: banks are dealers, repo counterparties, collateral users and holders of sovereign debt.
• Corporate credit: underwriting pipelines, loan standards and bank inventory influence spreads and new issuance.
• Foreign exchange: global banks are core liquidity providers and transmit cross-border funding stress.
• Commodities: banks finance inventories and trade flows while intermediating producer and consumer hedges.
• Derivatives: dealer balance sheets, margin and collateral requirements shape liquidity and positioning.
• Monetary policy: the market reaction depends not only on the central-bank announcement but on how banks reprice deposits, loans and risk.

Execution Is Only the Visible Beginning

A screen may report a fill in milliseconds, but execution is only the beginning of the trade lifecycle. The market must still establish who traded, for which account, at what price and quantity; calculate each party’s obligations; collect collateral where required; transfer money and assets; update the legal and accounting records; and resolve any discrepancy or failed delivery.

This work is divided loosely among three operational layers:

• Front office: receives the order, makes the investment or trading decision, prices the risk and executes the trade.
• Middle office: controls limits, validates allocations, measures exposure, monitors profit and loss, and oversees collateral and regulatory reporting.
• Back office: confirms, clears, settles, reconciles and records the transaction, while maintaining positions, cash balances and customer books.

The boundaries vary by firm, but the control principle is vital: the person who takes market risk should not also have unrestricted power to confirm, value and settle it. Barings demonstrated what can happen when trading and settlement controls are not genuinely independent.

What the Back Office Actually Does

Banks appear at almost every stage—as broker-dealers, futures commission merchants, clearing members, settlement banks, custodians, prime brokers, cash lenders and providers of intraday liquidity. Even when an exchange or clearing house is the named market utility, bank accounts, credit lines and payment systems usually move the cash beneath it.

Clearing Houses: Concentrating and Controlling Counterparty Risk

A clearing house stands between market participants after an eligible trade is accepted for clearing. As a central counterparty, or CCP, it becomes the buyer to every clearing seller and the seller to every clearing buyer. The trader generally accesses it indirectly through a clearing member: an FCM in listed futures or a clearing broker in securities.

The CCP validates trades, nets obligations, collects margin and default-fund resources, marks positions to market, monitors concentration and conducts stress tests. If a clearing member defaults, the CCP follows a rule-based default-management process that may include using the defaulter’s collateral, hedging or auctioning its portfolio and drawing on defined financial resources.

Clearing does not abolish risk; it transforms and concentrates it. Bilateral counterparty risk becomes exposure to a highly protected but systemically important utility and its membership network. This makes strong governance, margin models, liquidity arrangements, operational resilience and credible default procedures essential. A clearing house can stop one dealer failure from producing a chaotic chain of unpaid bilateral trades, but a problem inside the clearing system itself can become a market-wide event.

The Futures Trade Lifecycle

1. Account and margin: the trader opens an account with a futures broker or FCM and deposits funds. Futures margin is a performance bond, not a deposit toward ownership of the underlying asset.
2. Order routing: an order is checked against credit and risk limits and routed to the exchange’s order book.
3. Execution: compatible buy and sell orders match. The exchange reports the fill, but the original counterparties do not normally remain exposed directly to one another.
4. Trade processing: the trade is matched, valued, checked for margin and allocated to the correct account and clearing member. Give-ups or transfers may move it to another FCM under established arrangements.
5. Central clearing: the clearing house becomes the counterparty to its clearing members. The FCM guarantees its customer’s obligations to the clearing house and must keep customer collateral segregated from its own property under the applicable rules.
6. Initial margin: the customer posts the broker’s requirement; the clearing member separately posts required resources to the clearing house. A broker may demand more margin than the exchange minimum.
7. Daily and intraday settlement: open positions are marked to the exchange settlement price. Losses are debited and gains credited as variation margin, preventing unpaid exposure from simply accumulating until expiry.
8. Position management: the trader may maintain, add to, reduce, roll or offset the position. Falling below required margin can trigger an immediate demand for funds or liquidation.
9. Expiry: most speculative positions are closed or rolled before expiry. Remaining positions follow the contract specification—cash settlement for many financial contracts or a regulated delivery process for physically deliverable commodities.
10. Final reconciliation: the FCM, clearing member, clearing house and settlement banks reconcile positions, cash, fees, margin and any delivery obligations.

CME Clearing describes post-execution processing as trade matching, valuation and margin verification followed by transfers, allocations and clearing cycles. Its daily mark-to-market process turns each day’s price change into cash profit or loss. This is why a futures trader must understand liquidity and margin—not only market direction.

The Stock Trade Lifecycle

The following is the standard US broker-to-broker lifecycle for an eligible stock trade. Other jurisdictions use different depositories, clearing houses and settlement timetables.

1. Order and execution: the investor sends an order through a broker. It is routed to an exchange, market maker or alternative trading system and matches with contra-side liquidity.
2. Trade capture: the broker records the fill and reports or submits it to the appropriate post-trade systems. Institutional trades are allocated among funds or accounts and matched or affirmed rapidly.
3. Clearing: for eligible US broker-to-broker equity trades, the National Securities Clearing Corporation acts as CCP, guarantees qualifying transactions and calculates each member’s obligations.
4. Netting: thousands of purchases and sales are compressed into net cash and net securities positions. NSCC says this reduces the value of payments that must be exchanged by an average of approximately 98% each day.
5. Preparation for settlement: the buyer must provide cash and the seller must have the shares available. Custodians, brokers and settlement banks confirm standing instructions, funding and inventory.
6. Settlement: most US broker-dealer securities transactions now settle on T+1—one business day after the trade date. DTC makes electronic book-entry movements of securities while cash obligations are completed through the settlement-banking and Federal Reserve payment arrangements.
7. Delivery versus payment: the process coordinates securities delivery with payment so that one side is not intentionally completed without the corresponding obligation, subject to the system’s rules and available positions.
8. Custody and beneficial ownership: the investor usually sees the shares credited in a brokerage account, while the depository, broker and custodian maintain the layered records beneath that entitlement.
9. Asset servicing: dividends, voting rights, splits, tender offers, tax treatment and reorganisations are passed through the custody chain.
10. Fails and short sales: if shares or cash are unavailable, settlement can fail and the position enters fail-management or buy-in procedures. A short seller must also arrange or maintain a stock borrow and eventually purchase shares to return them to the lender.

The US standard shortened from T+2 to T+1 on 28 May 2024. The change reduces the time during which counterparties remain exposed, but it also compresses the operational window for allocations, foreign-exchange funding, stock borrowing and correcting errors. NSCC performs the central-counterparty and netting role; DTC is the central securities depository that completes book-entry movements and supports custody and asset servicing. They are related DTCC subsidiaries, but clearing and depository settlement are distinct functions.

Futures and Stocks: The Operational Difference

The banking indicators worth watching

• deposit inflows, outflows and funding costs;
• loan growth and lending standards;
• net interest margin;
• non-performing loans and credit-loss provisions;
• capital and liquidity ratios;
• repo conditions and demand for central-bank facilities;
• investment-banking fees and issuance pipelines;
• trading revenue and market-making inventory;
• commercial real-estate, consumer and sovereign exposure; and
• connections to hedge funds, private credit and other non-bank institutions.

A rising policy rate can initially support interest income, but the effect is not unlimited. Funding costs may catch up, bond portfolios may lose value, refinancing becomes harder and non-performing loans can increase. The market therefore moves from celebrating higher margins to questioning asset quality and capital. That transition is often where a banking story becomes a system-wide market story.

A Short Timeline of the Global Banking System

The ATN Conclusion: Banks Are the Operating System, Not Just Another Sector

The physical form of banking has changed—from clay tablets and merchant benches to branch networks, trading screens and cloud infrastructure—but its essential economic function has not. Banking converts trust into transferable claims and present purchasing power into future obligations.

The City of London’s contribution was to assemble merchant finance, sovereign debt, insurance, foreign exchange and securities dealing into an international ecosystem. Empire extended that network, often through relationships that combined genuine economic development with political power and extraction. The Eurodollar market preserved London’s role after sterling declined. Bretton Woods created a new layer of international monetary and development institutions. The Big Bang then supplied the corporate and technological structure of the globally integrated investment bank.

The same network concentration that makes international finance efficient also creates geopolitical power. Dollar clearing, correspondent accounts, cards, custody and financial messaging can become channels for sanctions. Their use against designated Iranian and Russian institutions has encouraged BRICS members and other states to build alternatives, but the resulting change is gradual diversification rather than the immediate replacement of the dollar or SWIFT.

Today, banks share financial power with central banks, asset managers, private funds, exchanges and technology platforms. Branches may become apps and deposits may become tokens, yet banks remain indispensable because they create deposit money, provide payments, allocate credit, intermediate risk and connect markets to central-bank settlement.

For traders, the decisive question is rarely whether banks matter. It is whether their balance sheets are absorbing risk or transmitting it. When bank capital, funding and confidence are strong, the system can finance growth and market liquidity. When those foundations weaken, the same network can convert a local credit problem into a global financial event.
