On April 30 the US Treasury and IRS updated guidance on the Sustainable Aviation Fuel tax credit, making soy biodiesel eligible if producers use no-till and cover crops. Chicago July soybean oil fell 5.6% that week amid South American supply and the new subsidy calculation.
Changes to biofuel subsidy eligibility alter feedstock demand for soybean oil, and the reported price decline reflects pressure from rising South American supply.
After 351 past bearish policy events, Soybean Oil moved a median -0.0% over 5 sessions (49% higher; middle half -1.7% to +1.8%), and -0.2% 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.
Updated Treasury/IRS guidance on the SAF tax credit and the new subsidy calculation weighed on soyoil, though the Apr 30 guidance postdates the move and likely drove later losses.
