Brazil’s 2026/27 summer corn planting reached 51.2% of expected area, up 7 percentage points on the week and ahead of both last year’s pace and the multi-year average. Planting is nearing completion in Paraná but remains slow in Rio Grande do Sul, where some weather-related losses have been reported; soybean planting reached 66.8% of its area, with excess moisture slowing work in parts of the South and São Paulo.
Planting ahead of the usual pace reduces the risk of delayed sowing and is mildly bearish for crop-supply risk. Local weather-related setbacks in Rio Grande do Sul and wet conditions affecting soybean planting provide some counterweight.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
