A Congressional Research Service report explains the Renewable Fuel Standard's statutory structure, scheduled volume mandates and EPA waiver authority for the general, cellulosic and biomass-based diesel categories. It describes how waivers and volume modifications affect the program's outcomes.
Understanding waiver authority helps buyers judge how much biofuel demand for corn and vegetable oils could change under future EPA actions.
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, Soybean Oil moved a median +0.1% over 5 sessions (52% higher; middle half -1.6% to +2.0%), 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.
