A farmer in Iroquois County, Illinois, reported harvest was nearly complete, with 8% of acreage— all corn—remaining. Despite recent light rain and little more expected, corn yields were running 15% below the five-year average; soybean prices and local corn prices were also reported for November 5.
Below-average local corn yields imply tighter nearby supply in the affected area and are supportive for corn prices at the margin. The report is a single-farm-area observation, so its broader market impact is limited.
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.
