Southern Brazil's first corn crop is suffering from hot, dry weather during pollination and grain filling. Parana's corn good rating fell 13 points in one week, and north-central Rio Grande do Sul farmers report losses of 70% to 90% with some fields cut for silage.
Brazil's first-crop corn is a meaningful share of its supply and losses tighten export availability, supporting corn and feed-ingredient prices like DDGS and corn meal substitutes.
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.
