Chicago Board of Trade corn futures eased on Wednesday as the US dollar firmed and as the spread of coronavirus beyond China stoked concerns about a potential hit to global economic growth, traders said.

Corn futures were also anchored by ample supplies, with US farmers expected to increase plantings this spring.

Solid export demand underpinned the market. Export sales of US corn last week were estimated at 800,000 to 1,300,000 tonnes following sales of around 1.25 million tonnes the prior week. The US Department of Agriculture is due to release the weekly data on Thursday morning.
