CBOT soybeans rose nearly 20 cents in the week ended October 18 to $9.835 per bushel, while December corn gained 2.5 cents to $3.485. Analysts cite a USDA cut to the national soybean yield and strong Chinese buying.
Corn harvest is slow due to high moisture, and attention is shifting to dry conditions in northern Brazil and wet conditions in southern Brazil and northern Argentina.
Strong Chinese demand and a USDA yield cut support soybeans, while South American weather concerns add upside risk for the coming crop.
