The AI import bill: why tariffs have not shrunk the US trade deficit

At a glance: The US goods and services deficit rose 13.7% to $105.6bn in August 2026, the Bureau of Economic Analysis reported on 7 October, as imports climbed 4.3% to $420.8bn. Capital goods imports rose $6.2bn, led by semiconductors. Research from the Federal Reserve Bank of Minneapolis finds that AI-relevant imports reached $379bn in 2025 and that about 69% of them are exempt from tariffs. For leaders, AI investment is now a trade story as well as a technology one.

The August numbers

According to the Bureau of Economic Analysis and the Census Bureau, the US deficit in goods and services rose by $12.7bn in August to $105.6bn, from a revised $92.8bn in July. Exports rose $4.5bn to $315.2bn. Imports rose $17.2bn to $420.8bn.

The widening was almost entirely in goods. The goods deficit increased $12.8bn to $136.6bn, while the services surplus was essentially unchanged at $31.0bn.

On the import side, two categories did most of the work. Industrial supplies rose $9.1bn, including crude oil (up $3.3bn) and non-monetary gold (up $3.1bn). Capital goods rose $6.2bn, led by semiconductors (up $2.4bn) and other industrial machinery (up $1.3bn). Computer accessories, by contrast, fell $1.6bn.

The monthly figures need context. Year to date, the deficit is $138.2bn, or 19.9%, smaller than in the same period of 2025, when imports surged ahead of new tariffs. But the three-month average deficit, at $89.9bn, is $25.4bn higher than a year earlier. The direction of travel in recent months is towards a wider gap, not a narrower one.

By partner, the largest August deficits were with Mexico ($27.7bn), Vietnam ($24.0bn), Taiwan ($18.3bn) and China ($16.4bn).

The AI factor

A single month's data cannot prove a cause. The most detailed public analysis of the AI effect comes from the Federal Reserve Bank of Minneapolis. In a staff report published in 2026, monetary adviser Michael Waugh classified more than 18,000 traded products by their relevance to AI infrastructure and identified 645 high-relevance product codes.

The findings are striking:

• Scale: AI-relevant imports totalled $379bn in 2025, 72.6% above their 2023 level. Imports with low AI relevance rose only 2.5% over the same period.
• Momentum: by January 2026, monthly AI-relevant imports were 111% above their 2023 average, while low-relevance imports were 14% lower.
• Deficit effect: "Without the effects of AI on trade, the U.S. trade deficit would have been 16 percent smaller in 2025," the Minneapolis Fed concluded.
• Breadth: the category goes well beyond microchips, covering circuit boards, electric power equipment, cooling systems, telecommunications and networking gear. Imports of refined copper cathodes have risen 150% since 2023.

Exports have grown too, but more slowly: AI-related exports were 35% higher in 2025 than in 2023.

Why tariffs have not moved the numbers

The Minneapolis research offers a direct answer to the question in this article's title. AI-relevant goods faced an effective tariff rate of 4.5%, compared with 12.1% for other goods. About 69% of AI-relevant imports were covered by tariff exemptions.

In other words, the products growing fastest in the import bill are the ones tariff policy has largely spared. In WCRC's analysis, policymakers have, in effect, prioritised the domestic AI build-out over the bilateral trade balance. Waugh's report suggests AI may be "even more important than dramatic changes in U.S. trade policy" in shaping trade flows.

Supply chains have shifted as well. Taiwan and Mexico each supply about a quarter of US AI-relevant imports. Mainland China supplies less than 10%, less than Vietnam or Thailand, and its share has fallen since 2023.

Reading the deficit in an AI economy

In WCRC's analysis, three conclusions follow for business leaders.

First, a wider deficit is not necessarily a sign of economic weakness. Much of the increase reflects investment goods, the servers, chips, power systems and cooling equipment going into data centres, rather than consumer spending. Economists differ on how to read this; some, such as Donald Boudreaux of George Mason University, have described the widening as good news for the US economy.

Second, the policy tension is unresolved. An administration committed to narrowing the deficit is also committed to winning the AI race, and the second goal currently requires imports. Leaders should expect continued debate over whether exemptions for AI hardware remain, narrow or expand.

Third, the AI supply chain is concentrated. With Taiwan and Mexico supplying around half of AI-relevant imports between them, disruption in either would hit data-centre timelines quickly.

What it means for leaders

• Treat AI hardware exemptions as a policy risk. Data-centre and infrastructure budgets assume today's low effective tariffs. Model a scenario in which exemptions narrow.
• Look beyond chips. Power equipment, cooling, copper and networking gear are part of the AI import bill and may face tighter supply than semiconductors.
• Map exposure to Taiwan and Mexico. These two partners supply about half of US AI-relevant imports.
• Read trade data with care. Monthly swings in gold and crude oil can move the headline as much as AI goods do.

Quick answers

Q: How large was the US trade deficit in August 2026? A: The Bureau of Economic Analysis reported a goods and services deficit of $105.6bn, up 13.7% from a revised $92.8bn in July. Imports rose 4.3% to $420.8bn.

Q: How much does AI add to US imports? A: Research by the Federal Reserve Bank of Minneapolis found AI-relevant imports reached $379bn in 2025, 72.6% above 2023, and that the 2025 deficit would have been 16% smaller without AI's effect on trade.

Q: Why have tariffs not reduced the deficit? A: According to the Minneapolis Fed, AI-relevant goods face an effective tariff rate of 4.5%, against 12.1% for other goods, and about 69% of AI-relevant imports are covered by exemptions.
