The CNA presented its climate and market outlook for Brazil's 2022/23 first harvest, with an 82% probability that La Niña persists through October to December. Rainfall is expected to be significant in central and northern Brazil but lower in the south, particularly Rio Grande do Sul and part of Santa Catarina.
Likely drier conditions in southern Brazil raise the risk of soybean and corn losses there, which supports prices. Forecast rain in central Brazil partly offsets this, limiting the upside.
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.
