Illinois farmers report highly variable yields, with corn averaging 167 bushels per acre, 1.4 below USDA, and soybeans averaging 48 bushels, 1.1 above USDA. The season began with floods, included drought in some areas, and ended with an October blizzard.
Yields well below last year and a likely first below-normal crop in seven years point to tighter corn supplies, though grower reports came in close to USDA estimates.
After 1,465 past bullish weather events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 324 past neutral weather events, SOY moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
