RIN credit prices for biomass-based diesel (D4) and ethanol (D6) stayed high in 2022, with D4 peaking at $1.91/gal on April 28 and D6 at $1.68/gal on June 7. The EIA attributes the high D4 prices to rising feedstock costs that made biodiesel more expensive than petroleum diesel, which increased blending incentives.
The Gulf Coast biodiesel spot price peaked at $8.36/gal the same day.
Higher RIN values signal that blending biofuel is costly relative to petroleum, which supports demand for vegetable oils used as feedstock and keeps soybean oil prices firm.
After 842 past bullish policy events, Soybean Oil moved a median +0.2% over 5 sessions (52% higher; middle half -1.6% to +2.1%), and -0.5% over 20.
