Mato Grosso soybean planting accelerated to 75.81% of the 2026/27 area by October 23, up almost 24 percentage points in a week. Planting in the Midnorth and West regions is well advanced, supporting a timely second-crop corn window.
A fast Mato Grosso planting pace reduces weather risk for Brazil's largest soy state and supports a normal corn second crop, a mildly bearish supply signal.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
