US soybean and corn futures rose on 17 July after USDA reported that good-to-excellent ratings fell to 69% for soybeans and 72% for corn, down from the prior week. Hot, dry weather drove the decline, and traders also hoped for a resolution to the US-China trade dispute.
Lower crop conditions during the key pollination and August soybean development period raise yield risk and support prices, though the ratings are still relatively good by historical standards.
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.
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.
