USDA's November WASDE lowered the 2026-27 US corn yield to 179.6 bu/acre from 181 and cut production by 141 million bushels. It raised the soybean yield to 53.3 bu/acre and lifted soybean export projections by 25 million bushels, trimming soybean ending stocks to 300 million bushels.
A smaller US corn crop and tighter soybean stocks raise feed-grain and soymeal costs for buyers, since both ending-stock estimates are now lower.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
