Brazil's statistics agency IBGE forecasts grain output will fall 2.6% in 2027, from 355.8 million to 346.6 million tonnes, a drop of 9.2 million tonnes after an estimated record 2026 crop. Corn accounts for most of the decline, with 8.1 million tonnes less, while harvested area stays nearly flat at 83.2 million hectares, implying lower yields.
A smaller Brazilian corn crop in 2027 would tighten export availability and support corn prices, and it adds to feed-cost pressure for buyers reliant on Brazilian supply. The forecast cites a possible strong El Niño and higher input costs as risks.
After 1,051 past bullish report events, Corn moved a median +0.6% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
