Above-average temperatures and irregular rainfall are raising crop water demand in Brazil’s Matopiba soybean region at the start of the 2026/27 season. In several locations, temperatures were more than 2°C above normal, with anomalies as high as 3.6°C in Bahia; the conditions coincide with a strengthening El Niño.
Higher evaporation and uneven rainfall can reduce soil moisture and jeopardize soybean planting and establishment, creating upside risk to prices if crop conditions deteriorate. The article describes a developing weather risk rather than confirmed widespread crop losses.
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.
