Grain futures fell sharply on Friday, November 14, after USDA trimmed its national corn yield by 0.7 bushels to 186, two bushels above the average trade guess. Traders had expected deeper cuts due to disease and late-season stress, and China's soybean purchases were also cited as a factor.
A smaller-than-expected yield cut means more corn supply than the market had priced in, keeping feed grain costs low. The price reaction reflects a bearish surprise in the USDA data.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
After 788 past bearish report events, Soybeans moved a median -0.3% over 5 sessions (47% higher; middle half -2.0% to +1.5%), and -0.9% over 20.
After 1,006 past bearish report events, Wheat (SRW) moved a median +0.0% over 5 sessions (50% higher; middle half -1.6% to +1.8%), and +0.3% over 20.
