Corn, soybeans and wheat rallied at the close on December 26, 2023 after forecasts showed hot, dry conditions persisting in central and northern Brazil. Corn closed up 4 cents, January soybeans up 2 cents, and wheat 6 to 13 cents higher.
Livestock futures also closed higher, with February hogs up $1.42.
Dryness in Brazil threatens its safrinha corn and soybean crops, which supports prices for US exports and feed ingredients. Traders are pricing in the risk of smaller South American supplies.
