US grain futures rallied after weekend frost in Kansas, Colorado and Oklahoma and flooding in Arkansas, Nebraska and Illinois forced some growers to overseed. Wheat on CBOT reached a six-week high on Monday, with corn and soybeans also higher.
The full extent of the crop damage remained unclear.
Confirmed losses and resowing point to lower near-term production, supporting corn, soybean and wheat prices. The price response shows the market is reacting quickly to weather risk in key growing areas.
After 1,072 past bullish weather events, WHEAT moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
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, SOY moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
Weekend frost and flooding forced overseeding and drove a broad CBOT rally on May 1, with corn higher on potential planting and replanting losses.
