Farm Progress reported that USDA's Sept. 1 corn stocks came in near 2.1 billion bushels, up 35% year over year and a seven-year high, sending futures to six-week lows.
Soybean and wheat stocks were down from a year earlier, and USDA trimmed the 2025 corn crop slightly.
Record-scale old-crop corn supplies weigh on feed grain prices, lowering feed costs for buyers while soybean stock declines offer limited support.
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 563 past neutral report events, SOY moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
