WRI Brasil published a study finding the rainy season in parts of the Amazon shortened by up to 75 days and in parts of the Cerrado by up to 45 days over 1993-2023. It estimates each 1°C rise above 35°C could cut soybean yields by about 6%, with China as the main customer.
A structural climate risk to Brazilian soybean yields and beef output could support longer-term soymeal and feed prices, though the study is a long-run analysis rather than a near-term crop event.
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 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.
After 20 past neutral weather events, Live Cattle moved a median +0.4% over 5 sessions (60% higher; middle half -0.3% to +1.2%), and +3.0% over 20.
