Truck arrivals at Rosario, Argentina's main grains port, carrying soybeans and corn fell to the lowest level in at least 22 years in March-May. The drop follows a historic drought that cut soybean output 49% and corn output 37% from the previous season.
The Rosario exchange forecasts 21.5 million tonnes of soybeans and 32 million tonnes of corn.
Sharply lower Argentine supply of soybeans, corn and meal reduces global export availability and supports prices. Brazil may gain share in soy exports as a result.
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 1,465 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 453 past bullish weather events, Soybean Meal moved a median +0.5% over 5 sessions (55% higher; middle half -1.6% to +2.7%), and +0.5% 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-low truck arrivals at Rosario on 2023-06-13 signal tight Argentine soy and meal export supply, which supports global meal prices right before the 4.43% jump.
