How Have Tariffs Worked So Far?

If you look at the year-to-date (YTD) data, the message is fairly clear:
higher tariffs have not worked so far.
However, the reason is not just the outcome, but the structure and timing of the data itself.

To understand what tariffs have (and have not) achieved, 2025 must be split into two distinct periods.

January–March 2025: The Legacy Tariff Effect

During the first quarter of 2025, the U.S. economy was still absorbing the effects of
previous tariff regimes. Ahead of tariff changes, the system had already
imported goods for roughly nine months.

This front-loading of imports led to:

• A large and persistent trade deficit
• Excess inventories across multiple sectors
• A drag on growth, pushing Q1 GDP into negative territory

These outcomes were largely locked in before new tariff policies could influence behavior.
Nevertheless, fears intensified that renewed Trump-era tariffs would further damage growth,
even though the data mainly reflected earlier decisions.

April–September 2025: Year-on-Year Deterioration

The second period paints a different but equally problematic picture.
Trade balance data compared to the same period a year earlier remains
negative.

In practical terms:

• Import volumes remain structurally high
• Domestic substitution has been limited
• Supply chains have not meaningfully re-shored

This dual situation—legacy imports early in the year and deteriorating year-on-year data later—
prevents a clean assessment of tariff effectiveness.

The Inventory Overhang

One of the most important distorting factors is that
inventories are still elevated.
As long as companies are running down stockpiles accumulated before tariff changes,
import behavior will not normalize.

For this reason, meaningful conclusions will only be possible in the
February–April 2026 window, once inventories, contracts, and logistics cycles
have fully reset.

Tariffs and the Treasury Deficit

Tariffs can appear successful in one narrow sense:
they increase government revenue.

Higher tariff collections can reduce the Treasury deficit on paper.
However, this is a fiscal accounting effect, not a systemic improvement.
The broader economic system reacts very differently.

Why Tariffs Do Not Work for the System

1. A Wider Trade Deficit in Value Terms

The U.S. continues to import what it does not produce.
When tariffs raise prices but not volumes, the
nominal trade deficit can widen,
even if import quantities are unchanged.

2. Inflationary Pressure on Goods

Tariffs act as a direct tax on goods.
They raise:

• Input costs for producers
• Wholesale prices
• Retail prices for consumers

This is cost-driven inflation, not demand-driven growth.
Real purchasing power declines, even if nominal spending holds up.

3. Lower Real Consumption

Higher prices force consumers to trade down, delay purchases,
or cut discretionary spending.
This weakens real consumption and reduces economic momentum.

4. Capital Misallocation

Tariffs protect prices, not efficiency.
They can shield inefficient producers, reduce competitive pressure,
and discourage productivity-enhancing investment.

5. Supply-Chain Friction

Modern supply chains are global.
Tariffs introduce uncertainty, compliance costs, and delays,
encouraging firms to hold excess inventory and tying up working capital.

6. Indirect Financial Tightening

Tariff-driven inflation can limit the effectiveness of monetary easing,
keeping long-term yields elevated and tightening financial conditions
even when policy rates are cut.

Import Prices: The Hidden Constraint on the Tariff Narrative

Import prices of semi-finished and finished goods—particularly from Asia—have historically been
one of the greatest competitive advantages for U.S. companies.
These inputs have allowed firms to maintain margins, control costs, and offer consumers
lowest prices across a wide range of sectors.

As of September 25, 2025, import price data continues to show negative year-on-year figures in most sectors. This is a crucial point that is often missed in public debate.

This implies two structural realities.

• No inflationary pressure is coming from import prices themselves.
  Outside of tariffs, imported goods are not driving inflation.
  Any upward pressure visible in consumer or producer price indices
  is therefore far more likely to be the result of
  excessive tariff policy rather than market-driven cost increases.
  In this context, movements in the CPI or CPOI cannot be credibly attributed
  to foreign pricing behavior.
• The U.S. cannot produce semi-finished and finished goods at import prices.
  For the quantities currently imported, the domestic system lacks
  the necessary production capacity.
  More importantly, there are
  no large-scale investments in new plants planned in the short term
  that would allow meaningful substitution.

This creates a structural trap for tariff policy.
Imports remain indispensable, domestic alternatives are neither cost-competitive nor scalable,
and tariffs simply raise prices without changing underlying production realities.

In other words, tariffs are not correcting a market failure.
They are taxing a dependency that the system is currently unable to eliminate.

Conclusion: A Fiscal Gain, a Systemic Cost

So far, tariffs have not delivered systemic economic benefits.
The data is distorted by timing effects, inventory cycles,
and structural import dependence.

While tariffs may reduce the Treasury deficit through higher revenues,
they do so at the cost of higher prices, weaker real consumption,
misallocated capital, and reduced system efficiency.

In short:
tariffs may help the budget, but they may also weaken the economic system.
