IBGE projects Brazil's 2027 grain output will fall 2.6% to 346.6 million tonnes, about 9.2 million tonnes below its 2026 estimate. Conab, by contrast, expects growth in the 2026/27 crop year, and the two agencies use different reference periods.
Paraná expects a larger soybean crop despite delayed planting, wheat losses and climate risks.
The divergence between official forecasts adds uncertainty to Brazil's supply outlook for corn and soybeans. A smaller 2027 crop would support feed grain and soymeal prices, while Paraná's larger soy expectation offsets part of that.
After 775 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
