President Donald Trump has spent months arguing that America's trade deficit could be fixed with one simple instrument: tariffs. In September, the data finally gave him something to point to.
New Census Bureau figures released Thursday show the U.S. trade deficit narrowed to $52.8 billion in September, marking the smallest gap since June 2020. That's a meaningful improvement from August's revised $59.3 billion and well below economist expectations for a $63.3 billion deficit.
The Export Boom Meets a Slower Import Crawl
U.S. exports surged 3% to $289.3 billion, landing as the second-highest monthly figure on record. Industrial supplies and materials led the charge with a $7.2 billion increase, followed by nonmonetary gold up $6.1 billion. Consumer goods added $4.1 billion, and pharmaceutical products contributed another $3.1 billion.
Not everything went up, though. Computer exports dropped $2.3 billion, and service exports slipped $0.4 billion. Travel services fell $0.6 billion, and transport declined $0.2 billion, taking some shine off an otherwise solid month.
On the import side, things moved much more slowly. Imports edged up just 0.6% to $342.1 billion, a modest $1.9 billion increase that represents a significant slowdown from earlier in the year. Pharmaceutical imports led the way with a $12.9 billion surge, while nonmonetary gold added $1.9 billion and computer accessories rose $1.7 billion.
But those gains were offset by declines elsewhere. Computer imports fell $4.7 billion, crude oil slipped $1.3 billion, and electric apparatus dropped $1.5 billion. Service imports barely budged, ticking up just $0.3 billion thanks to transport and financial services.
Despite September's improvement, the year-to-date picture is less encouraging. The goods and services deficit rose $112.6 billion, or 17.2%, compared to the same period in 2024. Imports are up 7.7% year-over-year, while exports have climbed a slower 5.2%.
Looking at a three-month average, the deficit narrowed to $63.1 billion in the third quarter, compared with $77.1 billion in the same period in 2024, as exports rose by $10.4 billion and imports fell by $3.6 billion.
China Gap Narrows as Supreme Court Decision Looms
The U.S. recorded its biggest September deficits with Ireland at $18.2 billion, Mexico at $17.8 billion, and the European Union at $17.8 billion.
The deficit with China narrowed by $4 billion to $11.4 billion, driven by a combination of slightly higher U.S. exports, up $0.2 billion to $8.8 billion, and sharply lower imports, which fell $3.9 billion to $20.1 billion.
September's tightening trade gap arrives at an awkward moment for the Trump administration. The White House has championed tariffs and stricter trade measures as the key to reshaping economic relationships with major trading partners, particularly China. Now the Supreme Court is preparing to rule on the legality of roughly half of Trump's tariff package, a decision that could fundamentally alter U.S. trade strategy.
For now, prediction markets aren't optimistic about the tariffs surviving judicial review. Polymarket assigns just a 25% chance that the Court will uphold Trump's measures, setting up what could be a significant clash between the administration's trade ambitions and constitutional limits on executive authority.
