Cooler-than-normal April weather is slowing US corn planting, and soils in parts of the Corn Belt are very dry. Speculative funds have built their corn long position to a decade high on these weather risks.
Dry soils and slow planting raise the risk of yield losses and drought later in the season. Large fund long positions also add volatility to corn prices.
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.
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.
Record fund long positioning and planting delays/dry soils set up weather-driven buying that can amplify upside moves.
