Brazil’s 2026/27 first-crop corn planting reached 51.2% of the expected area by November 6, ahead of last year’s pace and the five-year average. Hail, strong winds and heavy rain caused irreversible damage in some areas of Rio Grande do Sul, while excessive moisture and low sunlight hindered early crop development in parts of Paraná and Santa Catarina.
Storm damage and unfavorable growing conditions could reduce yields in affected southern areas, lending some support to corn prices, although planting is progressing ahead of average nationally.
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.
