Wheat prices rose a third straight day after Russia said it would treat ships heading to Ukrainian ports as military cargo carriers. The move followed the Kremlin's withdrawal from the Black Sea Grain Initiative, and Chicago wheat traded about 1.4% higher at a three-week high after an 8.5% jump the prior session.
Threats to Ukrainian shipping raise the risk of lost Black Sea wheat and corn exports, supporting global grain prices and raising feed costs. The effect depends on whether shipments actually halt.

Wheat rallied a third straight day on Russia's threat to treat Ukraine-bound ships as military cargo carriers, which raises Black Sea supply risk and added to the move ending July 23.
