Chicago wheat futures rose more than 3% to a one-week high on February 16, 2021, after record cold in the US Plains raised fears of freeze damage to winter wheat. Analysts estimated that about 30% of hard red winter wheat was exposed to significant freeze risk, and corn and soybeans also firmed.
Potential damage to US hard red winter wheat would tighten wheat supplies and could lift wheat-based feed costs. Corn and soybean gains reflect a firm overall grain complex.
