Field visits by Aprosoja MT in southern Mato Grosso found irregular rainfall and high temperatures slowing soybean development. Some fields planted in late September have uneven rainfall and reduced moisture, leaving plants shorter than expected.
Producers are concerned about the 2026/27 crop in this key production state.
Mato Grosso is Brazil's largest soybean producer, so sustained dryness there could lower output and support soybean and meal prices. Current effects are localized, so the price impact is modest for now.
After 1,085 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (55% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
