Fastmarkets: US biodiesel margins struggle despite rising RIN prices

After factoring in fixed costs and the clean fuel production credit (45Z), net margins remained sharply negative for biodiesel producers.
Renewable identification number (RIN) prices have made a strong run over the past several weeks.
They were up by 32 percent over the three-week period ended April 11.
RINs closed the week at their highest price since Sept. 22, 2023.
While market participants often say that they need RINs to rise to make biodiesel/renewable diesel production profitable, what they really mean is that they need RINs to rise faster than the soybean oil/heating oil (BOHO) spread.
The BOHO measures the profitability of producing biodiesel from soybean oil.
The higher the spread, the more costly the production.
RIN prices often rise to offset the increase in production costs.
Unfortunately for producers, RIN prices did not keep pace with the rising BOHO over the past three-week period.
This led to a continued deterioration in margins.
The BOHO spread climbed by 68 percent during this period, while RINs managed to climb by 32 percent.
During the latest weekly period ended April 11, the BOHO spread increased by 10 percent while RINs only rose by 2 percent.
Vertically integrated soybean producers had been ramping up production to dispel growing soybean-oil inventory from the ongoing soybean crush.
Even in poor-margin environments, they can afford to do this due to positive soybean-crush margins or as an effort to provide value within the entire soybean chain.
But many vertically integrated producers are struggling as well and questioning why standalone biodiesel operators would pick this point to restart production.
“I have been scratching my head [as to why standalone biodiesel operators] have been ramping up lately,” an integrated producer said. “The last time margins were this low, [they] were vocal about idling capacity. The production margins don’t make sense now.”
