Soybean Crush Lags as RIN Generation Drops 33% Amid Biofuel Uncertainty
A 33% plunge in RIN generation tied to biodiesel plant idlings and regulatory uncertainty is dragging soybean crush below year-ago levels.
U.S. soybean crush is running below prior-year levels as renewable identification number generation tied to biomass-based diesel has plunged 33% year-over-year. The decline, driven by biodiesel plant idlings and unresolved policy questions, is squeezing margins across the soybean value chain and tightening the supply outlook for feed markets.
Biodiesel facilities have shuttered capacity amid persistent regulatory uncertainty. Implementation details for the 45Z clean fuel production credit remain unclear, and finalization of the Renewable Fuel Standard continues to hang over the sector. Without clarity on these policy frameworks, operators face diminished incentives to run at full capacity, and soybean oil demand from the biofuel sector has weakened accordingly.
The crush slowdown carries direct consequences for downstream buyers. Feed mills face reduced soymeal availability as processors pull back, while grain elevators are navigating shifting basis dynamics as soybean demand softens. The trend signals tighter margins for crushers caught between weaker biofuel economics and softening co-product returns.
Market participants are now watching for three developments that will shape the trajectory of crush rates and RIN generation: clarification of 45Z implementation rules, the timing and content of RFS finalization, and whether idled biodiesel plants return to operation. Until those questions resolve, soybean processing and biofuel credit markets will remain under pressure.
