Chicago soybean futures hit their highest since June 2014 at $14.60 a bushel on March 8, 2021, as dry weather in Argentina and excess rain in Brazil raised supply concerns. Corn and wheat also rose ahead of USDA crop forecasts.
Argentina is the world's top soymeal exporter, and a rain deficit threatening 30% of its soy belt plus Brazil's delayed harvest tightens meal supply and lifts feed input costs. Buyers should expect higher prices for soy-based feed ingredients.
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.
After 453 past bullish weather events, SBM moved a median +0.5% over 5 sessions (55% higher; middle half -1.6% to +2.7%), and +0.5% 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 1,072 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.
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.
On March 8, 2021 soybeans hit a near 7-year high on Argentine dryness and Brazilian excess rain, and corn rose alongside ahead of USDA data, so South American supply worries plausibly drove the one-day corn jump.
