Soybean futures fell nearly 6% in October, their largest monthly decline of 2026. Traders are watching the USDA’s November 9 reports, which could raise the agency’s record U.S. yield estimate of 53.1 bushels per acre; Brazil’s crop was 56% planted by the end of October, ahead of its five-year average.
A higher U.S. yield estimate could increase expected supplies and pressure soybean prices. Brazil’s large role in China’s imports and its planting progress also heighten competition for U.S. export demand.
After 788 past bearish report events, Soybeans moved a median -0.3% over 5 sessions (47% higher; middle half -2.0% to +1.5%), and -0.9% over 20.
