Ohio State economist Seungki Lee outlined three drivers of grain market swings: expanding Midwest drought, USDA's June Acreage Report with more corn and less soybeans, and the looming expiration of the Black Sea grain deal. About 98% of Minnesota cropland was in drought.
Drought risk is not fully priced in, and the shift toward corn acres lowers soybean supply, so volatility and upside risk for feed grains and meal remain elevated.
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.
After 1,072 past bullish weather events, Wheat (SRW) moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
