Epagri reports Santa Catarina soybean planting at 20.2% of the 2026/27 projected area as of October 24, slightly behind the 22.1% of a year earlier. Frequent rain, waterlogged soil and cool temperatures slowed machinery and caused some emergence failures and replanting.
Wheat harvest delays in Chapecó and Xanxerê also limited fields available for soybeans.
Slow planting in a small producing state has little effect on national supply. The delay is minor, and the lower rainfall now forecast could allow catch-up, so price impact is neutral.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
