USDA's March WASDE report raised US corn exports by 175 million bushels and added 50 million bushels for ethanol, cutting ending stocks by 2.25 million bushels. USDA lowered Argentina's soybean production by 7 million tonnes to 47 million, and cut US soybean exports by 35 million bushels.
Analysts expected Argentina's harvest to pressure soybean futures.
Reduced US corn stocks and stronger export demand support corn prices. Lower Argentine soybean output is offset by weaker US export business, which leaves soybean prices under pressure as Argentina's harvest advances.
