USDA's March 2026 WASDE left US corn and soybean domestic balance sheets largely unchanged, with corn ending stocks at 2,127 million bushels. Brazil's corn crop was raised 1 MMT to 132 MMT while Argentina's was cut 1 MMT to 52 MMT.
Small changes in South American corn supply and steady US stocks leave prices little changed, though Brazil's larger crop adds export competition for corn.
