Senator Chuck Grassley answered questions on the RFS and EPA, noting that the administration approved year-round E15 sales after the summer driving season. He said E15 sales rose more than 46% since the rule was lifted in late May.
He cited a 2017 USDA study finding corn ethanol emissions about 43% lower than gasoline.
Growing E15 sales support ethanol output and corn grind, which underpins corn demand. The piece is advocacy and does not introduce a new policy change, so its price effect is modest.
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.
