Soybean planting for the 2025/26 crop in Mato Grosso do Sul will begin on September 16 and may run until December 31. Cemtec forecasts irregular rainfall, above-average temperatures and a chance of isolated cold spells for the September to November period.
Irregular rain and heat during planting could affect establishment and yield in a major producing state. Market impact is modest unless the forecast worsens.
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.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
