Record Imports Expand the Trade Gap

The US goods trade deficit widened unexpectedly in September as demand for imported products surged, particularly equipment associated with the expansion of artificial intelligence infrastructure.

The deficit increased by $2.8 billion, or 2.1%, to $134.9 billion, according to data released by the Commerce Department’s Census Bureau. Economists surveyed by Reuters had expected a shortfall of $130.2 billion.

Goods imports climbed $8.1 billion, or 2.4%, to a record $344.1 billion. Exports also increased, rising $5.3 billion, or 2.6%, to $209.2 billion.

The widening gap continued a trend that developed throughout the third quarter, raising concerns about the contribution of international trade to overall economic growth.

AI Infrastructure and Consumer Demand Fuel Imports

Capital goods were a major contributor to the increase in imports. Their import value rose 7.5% in September and was up 77.2% from a year earlier, reflecting strong demand for equipment required by technology companies expanding their AI infrastructure.

The growing reliance on overseas hardware has increased the value of imported goods even as domestic investment in AI accelerates. Stephen Stanley, chief US economist at Santander US Capital Markets, attributed much of the widening trade gap to imported technology equipment.

Consumer demand also supported import growth despite rising living costs. Consumer goods imports increased 3.1% during the month, while imports of other goods rose 6.7%.

Not all categories advanced. Imports of industrial supplies, including gold and petroleum, fell 6.0%, while food and motor vehicle imports also declined.

Exports Increase but Fail to Offset Imports

US goods exports rose to $209.2 billion, supported by stronger shipments across several categories.

Food exports increased 12.8%, capital goods exports advanced 5.4%, and consumer product exports rose 6.5%. However, exports of motor vehicles and industrial supplies declined.

Although the export gains provided some offset, they were insufficient to match the increase in imports. Trade has now failed to contribute positively to GDP growth for three consecutive quarters, according to the report.

GDP Estimates Face Greater Uncertainty

The widening trade deficit raised the possibility of a substantial drag on third-quarter economic growth. Economists at Pantheon Macroeconomics estimated that trade could reduce GDP growth by four percentage points, while Oxford Economics estimated a 3.25-percentage-point impact.

The estimates come ahead of the government’s advance GDP report for the July–September quarter. Before the trade and inventory data were released, economists surveyed by Reuters had forecast annualized growth of 3.2%, following a 2.2% rate in the second quarter.

However, some imported goods remained in inventory rather than being sold immediately. Wholesale inventories increased 0.6% in September, while retail inventories rose 0.3%. Retail inventories excluding motor vehicles and parts increased 0.4%, a component that contributes to the GDP calculation.

These inventory changes could soften the estimated impact of trade on economic growth. Nevertheless, Pantheon Macroeconomics senior US economist Oliver Allen said growth of around 1% appeared more likely, while acknowledging the unusually high uncertainty surrounding the estimate.

What Investors Should Watch Next

The advance third-quarter GDP report will help clarify how much the widening trade deficit affected economic activity. Investors will also monitor whether strong AI investment and consumer spending can offset the drag from imports.

The figures highlight a distinction between domestic demand and domestic production: increased investment can support economic activity while simultaneously widening the trade deficit when equipment is sourced overseas. Future trade data, inventory accumulation and the pace of technology investment will therefore be important indicators of the economy’s underlying momentum.
