The November WASDE cut the U.S. corn yield to 179.6 bushels per acre from 181.2, removing 3.57 million tons from U.S. production. Argentina and Brazil each gained 2 million tons of corn, offsetting most of the loss and leaving global output only slightly lower.
The U.S. headline cut supported corn prices, but larger South American crops and higher global stocks limit the lasting tightness. The report also lowered EU corn import estimates, which weighs on European import demand.
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.
