Chicago wheat eased slightly from a four-month high on February 18 as cold temperatures posed threats to crops in the Black Sea and US Plains. Corn and soybeans were little changed, and the rally was seen as ahead of fundamentals, with physical overseas markets not following.
Cold-weather crop risk in key exporting regions supports wheat, but weak physical export demand suggests the rally may fade.
