The March WASDE left US ending stocks unchanged at 2.127 billion bushels for corn, 350 million for soybeans and 931 million for wheat. USDA trimmed Argentina's corn crop by 1 MMT to 52 MMT and raised Brazil's to 132 MMT, while Brazil's soybean crop stayed at a record 180 MMT.
The report was largely a non-event, so prices followed crude oil lower; the modest South American production shifts offer limited price support.
