USDA's June WASDE cut 150 million bushels from old-crop U.S. corn ending stocks, a bigger reduction than trade expectations. Brazil's corn crop was cut as expected, while the trade had looked for a lower total.
Global wheat production was raised, mainly for major exporters.
A larger-than-expected cut in U.S. old-crop corn stocks tightens the feed grain supply and supports corn prices. Feed buyers should expect firmer corn costs while oilseed balances stay tight.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% 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.
After 138 past bearish report events, Wheat (HRW) moved a median +0.0% over 5 sessions (50% higher; middle half -2.9% to +2.4%), and +0.5% 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.
The June WASDE (reported 2021-06-11) raised global wheat production, mainly for major exporters, which is bearish for wheat supply balances and plausibly drove part of the HRW decline, though the bullish corn stocks cut partly offsets it.
