July CBOT wheat rose 2.5% to $6.22 a bushel as dry weather expanded across western US wheat fields, including extreme drought in Nebraska and spreading dryness in Oklahoma and Texas. Corn rose slightly while soybeans fell, and crude oil climbed on Middle East tensions.
Expanding Plains drought threatens hard red winter wheat yields, supporting wheat prices. Higher crude oil also gives some support to corn and soy through biofuel demand.
