USDA cut Brazil's 2023/24 soybean crop by 4 million metric tons to 157 million and its corn crop by 2 million to 127 million on adverse weather and smaller safrinha area. Argentina's soybean crop was raised 2 million to 50 million, while its corn estimate was held at 55 million.
The shift is linked to the transition from La Niña to El Niño.
Lower Brazilian output tightens export supply for corn and soybeans, while Argentina's recovery partly offsets the shortfall, leaving prices supported on the corn side.
