Cooler, wetter July weather has spared U.S. summer crops from widespread disaster after a very dry start, but several Corn Belt areas are drying out again during a heat wave. Forecasts for August rainfall, which is critical for soybean yields, show no clear trend.
Uncertain August rainfall keeps traders reacting to each weather model run, so prices may swing on forecast changes rather than a clear direction.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% 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.
Cooler, wetter July weather spared US crops from widespread disaster, reducing the weather premium and supporting the drop in corn prices.
