Corn and soybean prices spiked after reports of Brazilian yield losses from drought and heat. Conab cut Brazil's soybean estimate far more than USDA, and high soy prices may prompt US farmers to shift acreage away from corn.
A larger Brazilian soybean shortfall tightens global soy supply and lifts soymeal costs for feed buyers, while possible US acreage shifts could later tighten corn.
