Central Brazil has had few showers since September 24, but scattered rains are now arriving, typical for mid-October. Early frontal rain allowed producers to start planting early, and Mato Grosso soybean planting reached 15% by October 3 against a six percent five-year average.
Early planting and a return of rain support expectations for a healthy soybean crop, which is modestly bearish for soybean prices.
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 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
