USDA's March WASDE left all U.S. corn and soybean supply and demand numbers unchanged, after traders had expected small cuts to carryover. Corn and soybean prices dropped sharply, then recovered, and closed the week within their recent ranges.
Attention turns to Brazil's safrinha corn and soybean harvest and the March 31 reports.
Unchanged U.S. carryover removed expected tightening, while the coming March 31 Prospective Plantings and Grain Stocks reports could move prices significantly.
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.
Unchanged WASDE numbers against expectations of carryover cuts caused a sharp price drop in corn, though prices partly recovered.
