Soybean planting in Paraná reached 71% of the planned 2026/27 area, but excessive rainfall has delayed fieldwork compared with recent seasons. Excess moisture, low sunlight and below-average temperatures have also reduced the share of soybean fields rated in good condition from 88% to 85%, while raising concern that the corn planting window could narrow.
Delayed and deteriorating soybean crops could constrain production prospects, while a shorter window for planting second-crop corn may increase its yield risk. These risks are supportive for soybean and corn prices if they persist.
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.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
