USDA's November WASDE report, released November 10, cut the 2026/27 US corn yield from 181.2 to 179.6 bushels per acre, reducing production by 141 million bushels to about 15.893 billion. US corn ending stocks fell 91 million bushels to 1.758 billion, while the season-average farm price was lowered by $0.10 to about $4.60 per bushel.
USDA also raised soybean production slightly, but expected exports to rise enough to absorb the extra supply, cutting US soybean ending stocks by 15 million bushels to 300 million.
Tighter US corn and soybean balance sheets raise the cost of energy and protein feed ingredients. Lower corn stocks and firmer soybean meal economics can shift buyers' relative preference toward meat and bone meal, poultry meal and other protein alternatives.
After 1,051 past bullish report events, Corn moved a median +0.6% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
