Rain and high humidity in Rio Grande do Sul delayed the soybean harvest, which reached 83% by the first half of May 2022. Some mature crops suffered pod opening and grain germination, and corn harvesting was nearly halted by heavy rains and soybean priority.
Harvest delays and weather damage in southern Brazil add modest supply uncertainty to soybean and corn, though the effect on prices is limited at the regional level.
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 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.
