A farmer in Champaign County, Illinois, said corn yields were down at least 10%, with results varying by area and influenced by drainage and other production factors. Soybean yields were generally similar to last year, with location and drainage affecting outcomes.
Lower local corn output could tighten nearby feed-grain availability and lend support to corn prices; the report gives no sign of a comparable change in soybean supply.
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, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
