Excess rain in early November in Paraná has waterlogged fields, slowed field operations and may force replanting in some areas. Paraná is among the states with the largest projected losses, with soybean planting 62% complete as of October 26 against 5.74 million hectares planned.
Projected losses of about 2.3 million tonnes would tighten Brazilian soybean supply for export and crushing, supporting soybean meal and oil prices if the damage is confirmed.
After 1,079 past bullish weather events, SOY moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
