Refiners are asking the Trump administration to suspend the requirement to blend corn-based ethanol into gasoline, citing compliance costs. Corn groups want the blending requirements expanded to offset idled biofuel plants and falling crop demand.
The outcome of this dispute will determine ethanol and biodiesel blending volumes, which drive corn and soybean oil demand. Competing lobbying leaves the direction of price impact uncertain.
After 439 past neutral policy events, CORN moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
After 196 past neutral policy events, SBO moved a median +0.1% over 5 sessions (52% higher; middle half -1.6% to +2.0%), and -0.5% over 20.
