The U.S. trade deficit is going to show a big increase in December.

The numbers: The U.S. trade deficit in goods jumped 8.5% in December, reflecting a big increase in imports after trade tensions with China eased.

The gap in goods climbed to $68.3 billion in the final month of 2019 from $63 billion in November, the government said Wednesday.

Economists polled by MarketWatch had forecast a $65.6 billion deficit.

Advance figures for wholesale trade, meanwhile, slipped 0.1% while retail inventories were unchanged in December.

What happened: Exports of goods rose 0.3% in December, but imports shot up 2.9%.

Imports had fallen in the prior two months as companies sought to time shipments based on the prospects of higher tariffs between the two countries amid an ongoing trade fight. Economists were expecting the deficit to rebound in December.

The government will release overall trade numbers for December next week, but the size of the trade deficit is generally tied to changes in exports and imports of goods. Trade patterns involving services such as banking and tourism rarely change much from month to month.

Big picture: The bigger trade deficit in December could spur Wall Street forecasters to trim estimates for U.S. economic growth in the fourth quarter. Yet it doesn’t show any fundamental change in the nature of an economy that’s growing a modest 2% or so.

Market reaction: The Dow Jones Industrial Average DJIA, +0.66% and S&P 500 SPX, +1.01% were set to rise in Wednesday trades for the second straight day as investor worries over the coronavirus have eased a bit.

The 10-year Treasury yield TMUBMUSD10Y, -2.19% was little changed at 1.62%.
