Cemaden identified 110 municipalities in Brazil’s North and Northeast at high or very high risk of drought affecting rain-fed corn and bean planting. Drought has already damaged some regional crops, while NOAA estimated an 83% chance of historically strong El Niño conditions from October to December.
Insufficient rainfall can disrupt planting and reduce yields, tightening local corn supplies and putting upward pressure on prices if losses spread. The risk is concentrated in non-irrigated production areas.
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.
