Oil and AI chip imports drive U.S. August trade deficit to expand to 105.6 billions, reaching a 17-month high

The US trade deficit continues to widen, with the AI infrastructure boom and tariff fluctuations driving imports to record highs, weighing on third-quarter GDP expectations.

On Tuesday, October 6, the US Department of Commerce released data showing that the goods and services trade deficit in August widened by 13.7% month-on-month to $105.6 billion, exceeding economists' expectations of $102.1 billion and marking the highest level since March 2025, during the import rush ahead of Trump's announcement of the so-called "reciprocal tariffs".

The expansion of the trade deficit is due to imports growing faster than exports. In August, US imports reached a record $420.8 billion, up 4.3% from July. Export value increased by 1.4% compared to July, reaching $315.2 billion.

The larger-than-expected deficit has dampened market expectations for third-quarter economic growth. Goldman Sachs lowered its third-quarter GDP tracking estimate by 0.3 percentage points to 3.1%, and the Atlanta Fed’s GDPNow model immediately cut its estimate by 0.1 percentage points to 3.7%.

Total imports rose 4.3% month-on-month in August, with capital goods showing especially strong performance. Imports of capital goods, including computers and accessories, semiconductors, and telecommunications equipment, rose by $6.2 billion from the previous month.

The month-on-month increase in semiconductor imports hit a record high, soaring by $2.4 billion in a single month, reflecting the ongoing expansion of AI data center construction. In the first eight months of this year, total imports of semiconductors, computers, and computer components increased by $23.4 billion year-on-year; semiconductor imports in the first eight months surpassed $9 billion, nearly double the amount of the same period last year.

Brad Setser, Senior Fellow at the Council on Foreign Relations, pointed out that data center spending has pushed the trade deficit to "the highest level since the import rush at the start of 2025," and that electronics were largely exempt from the Trump administration’s tariffs, which "is key".

Industrial goods (including oil and petroleum products) saw a nominal increase of $9.1 billion in imports month-on-month, with non-monetary gold imports also rebounding. Meanwhile, spending by travelers to the US fell to the lowest level since August 2023, causing service exports to stagnate.

The core logic behind the Trump administration's push for tariffs to narrow the deficit is facing increasing skepticism.

Since Trump's second term, the average monthly trade deficit has been $74.5 billion, slightly higher than the $73.8 billion monthly average during Biden's final year in office.

FWDBONDS Chief Economist Christopher Rupkey noted that with US labor costs too high and factory construction unable to keep up with demand, importers "have no good options," saying:

Despite government economic policies significantly increasing tariff costs on many imported goods, America’s dependence on foreign goods remains undiminished.

Nationwide financial economist Oren Klachkin offered a somewhat more optimistic interpretation:

Price increases somewhat exaggerate the data, but net trade will still drag on third-quarter GDP growth. We view this as a signal of strong domestic demand.

In the first eight months of this year, the cumulative goods and services deficit narrowed by about 20% compared to the same period last year, with the goods trade deficit also shrinking by approximately $11 billion year-on-year.

Grace Zwemmer, US economist at Oxford Economics, stated in a report that trade data is "likely to significantly drag on third-quarter economic growth." Recent AI demand and corporate restocking needs will keep imports strong, while the hedging effect of US oil exports on the deficit will be weaker than in the second quarter.

On the policy front, in February the Supreme Court ruled that Trump’s imposition of global tariffs under the International Emergency Economic Powers Act was illegal. Since then, the executive branch has sought other legal justifications to rebuild the tariff system. In July, the White House launched a new round of tariffs on more than 80 countries and regions and plans to impose additional tariffs on over 40 countries.
