The November WASDE cut US corn production by 3.57 million tonnes to 403.7 million tonnes for 2026/27, about 27 million tonnes below last year. December corn futures in Chicago rose about 2.2% to around $176.8/t after the report.
A tighter US feed grain balance supports corn prices, but a large global wheat surplus and strong South American corn supplies are likely to cap gains and create substitution pressure for feed buyers.
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.
