Trade Stays the Most Volatile Part of US GDP Growth

what happened

Trade was a notable drag on real US GDP growth in the third quarter and remains the most volatile line in the official growth data for 2026, according to a note from Glenmede analyst Michael Reynolds, as reported by Market Talk. He says trade has swung with tariff policy this year and is now shifting again as the import cycle tied to AI infrastructure spending picks up.

The broader economy is still growing well, in his view. It has absorbed a widening trade deficit and still expanded 3.4%.

why it matters

For markets, the unpredictability of trade within GDP matters: sharp swings in imports and exports change the read on underlying growth and can shift expectations for interest rates and the dollar. Solid growth despite a wide trade deficit points to resilient domestic demand, but quarterly swings add uncertainty to how the data should be read.
