Analyst Allison Thompson says recent price rallies in soybeans and corn were driven by South American dryness headlines, though Brazil's monsoon season typically starts in early October. She suggests the weather premium may be overdone, and notes funds are reducing short positions as harvest progresses.
Weather premium in Brazil-linked markets could fade if rains arrive on schedule, pressuring soybean and corn prices after the recent rally.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
