Arlan Suderman's midday commentary on October 12 said the grain markets were trading the WASDE numbers against a backdrop of weak equities and a strong dollar near 113.3. The report's most notable change was a drop in the US soybean yield to 49.8 bushels per acre, at the low end of trade guesses.
USDA also made balance sheet adjustments tied to the September 30 stocks report.
The soybean yield cut supports soybean prices, while the strong dollar and macro risk-off conditions can weigh on dollar-denominated commodity values.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
After 53 past bullish report events, US Dollar (Broad) moved a median +0.1% over 5 sessions (51% higher; middle half -0.4% to +0.5%), and +0.5% over 20.
