USDA's NASS announced it is eliminating the August Objective Yield field survey for corn and soybeans and will use satellite data plus a farmer survey for the August Crop Production report. Field surveys continue for September through November reports.
Removing a field survey may raise uncertainty in the August crop estimates, which have historically driven sharp corn and soybean price moves.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
After 563 past neutral report events, Soybeans moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
