A University of Missouri Extension article explains how saturated soils and flooding affect corn and soybean crops, including root oxygen loss and stunting. It cites NOAA data showing nine billion-dollar flood disasters in Missouri from 1980 to 2024, with flood frequency tripling from 2020 to 2024.
Excess moisture and replant risk can reduce yields and delay planting, supporting modest upside in corn and soybean prices if wet conditions persist.
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 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
