A spell of dry weather in Cascavel, Paraná, brought only 4.1 millimeters of rain over seven days, raising concerns about water stress in early-planted soybean fields. The dry conditions come as Brazil’s 2026/27 soybean planting advances rapidly, with 53% of the projected area sown by October 29, according to AgRural.
Moisture stress in young crops could threaten yields if dry weather persists, adding a weather premium to soybean supply expectations. The risk is localized and no production loss is confirmed.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
