Paraná's soybean planting reached 71% of the 2026/27 area of over 5.7 million hectares, lagging the last three seasons, according to state agency Deral. Excess rain has cut the share of crops rated good to 85% from 88% the previous week, while the share rated fair rose to 14%.
The wet, overcast conditions are also slowing plant growth.
Waterlogging and reduced sunlight cut yield potential and delay planting, which is a mild bullish factor for soybeans and meal in a state that is a significant producer. Impact on prices is limited while the rating decline stays modest.
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.
