USDA's Grain Stocks report showed US corn stocks at 2.095 billion bushels as of Sept. 1, above the trade estimate and the high end of expectations.
December CBOT corn fell about 21 cents to $5.0075/bu, and CIF New Orleans and FOB Gulf corn assessments dropped $8/mt or more.
Heavier old-crop corn supplies raise near-term carryout expectations and pressure corn and feed-grain prices, which lowers feed input costs for buyers in the near term.
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.
