ATI research puts 2026-27 US corn ending stocks at 2.087 billion bushels, above USDA's forecast of 1.849 billion, after lowering its export forecast by 180 million bushels on weak sales. USDA reported corn 60% harvested versus a 66% average, and Brazil's first-crop corn is 58% planted with production steady at 140 MMT.
Higher US stocks than USDA projects, driven by weak exports, are bearish for corn prices. Slow harvest progress is a short-term offset, and the market remains range-bound.
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.
