As of the USDA's latest update, 72% of Iowa's corn and 93% of its soybeans had been harvested, well behind last year's 97% and 99% by mid-November. September rain delayed harvest, and farmers are facing equipment damage and downtime.
A slow Iowa harvest delays grain marketing and can keep some supply in fields, while higher diesel and fertilizer costs add to producer expenses. The effect on prices is modest because the delay is a timing issue for a major crop state.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% 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.
