The U.S. trade deficit widened to $105.6 billion in August, the Commerce Department reported Tuesday, marking the broadest gap since March 2025 and exceeding analyst expectations by more than $3 billion.

Imports climbed 4.3% for the month. The deficit swelled 13.7% from July, outpacing the Dow Jones consensus forecast of $102 billion. The Commerce Department attributed the surge partly to goods tied to artificial intelligence infrastructure buildout and fluctuations tied to tariff implementation.

The August deficit represents the widest monthly gap recorded since just before President Donald Trump announced reciprocal tariffs against U.S. trading partners in March 2025.

Despite the monthly spike, the year-to-date deficit stood at $138.2 billion through August, down nearly 20% compared to the same period in 2024.

Oren Klachkin, financial economist at Nationwide, said rising prices inflated the trade figures but that "net trade is set to drag on Q3 GDP growth." He characterized the data as evidence of "strong domestic demand, not economic weakness." Imports typically subtract from GDP calculations, though stronger domestic consumption can offset that drag elsewhere in the economy.

The trade report prompted major forecasters to trim third-quarter growth estimates. Goldman Sachs cut its tracking estimate for Q3 GDP to 3.1%, down 0.3 percentage point from its previous projection. The Atlanta Federal Reserve's GDPNow tracker lowered its estimate to 3.7%, a 0.1 percentage point reduction from its last update following the trade data release.
