CBOT corn settled up 1.3% at $3.71 per bushel on August 28 after Agriculture Secretary Sonny Perdue said the Trump administration is looking for ways to boost US biofuel demand. Soybeans rose modestly while wheat fell on ample Black Sea and EU supplies.
A possible policy push to lift ethanol demand would support corn prices by adding to usage, though no timeline or specifics were given. Wheat remains pressured by competing export supplies.
After 318 past bullish policy events, CORN moved a median -0.1% over 5 sessions (48% higher; middle half -1.4% to +1.5%), and -0.2% over 20.
After 356 past bullish policy events, SOY moved a median +0.1% over 5 sessions (53% higher; middle half -1.2% to +2.3%), and -0.9% over 20.
After 122 past bearish policy events, WHEAT moved a median -0.3% over 5 sessions (44% higher; middle half -1.9% to +1.2%), and +0.4% over 20.
