Brazil's corn output has risen to roughly 100 million tonnes, making it the third-largest producer and second-largest exporter globally. Productivity gains, especially insect control technology, drove the increase, and the second-crop (safrinha) system after soybeans now accounts for over 70% of production.
A structurally larger Brazilian crop that is increasingly planted after soybeans expands export supply competing with US corn, which is mildly bearish for corn prices and reinforces Brazil's export competitiveness.
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.
