A moisture corridor is forecast to bring more frequent rain to central Brazil, the Southeast, and Matopiba starting Sunday, November 8, supporting soil-moisture recovery and soybean planting. The system is expected to remain active through Tuesday before weakening, with 30–50 mm forecast in parts of the producing regions over five days.
The rainfall could relieve dry conditions and improve soybean establishment, reducing near-term crop stress and potentially easing weather-related price premiums if the forecast verifies. Its short duration means the relief may be limited, especially in areas with ongoing soil-moisture deficits.
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.
