Understanding the Disconnect in the Biofuels Market

The biofuels market ended the week with a growing disconnect between financial diesel scarcity and physical diesel consumption in the United States. D4 RINs surged to $2.20 for Dec26 and $2.25 for Dec27, extending the move that we highlighted yesterday as compliance economics tightened aggressively against refiners. At current values, the RIN market is no longer a secondary compliance cost. It is becoming a direct transfer of margin away from standalone refining and toward renewable fuel producers and integrated blenders. This is politically explosive.

Current Market Conditions

The timing is critical because the refining complex remains under acute prompt stress. June Brent settled at $103.43/bbl while Jun/Dec Brent backwardation widened to +$15.18/bbl. June WTI settled near $96.47/bbl with Jun/Dec backwardation still near +$25.99/bbl. June ICE gasoil closed around $1116/mt despite a sharp Friday correction of more than $50/mt, while Jun/Dec gasoil backwardation remained above +$200/mt at +201.25 after trading above +300/mt earlier this week. Heating oil futures remained historically elevated with June HO at $3.8870/gal, still up 62.3% over three months.

Against that backdrop, the spike in RINs is dramatically improving biofuel economics. Conventional biodiesel crush margins based on soybean oil improved toward $0.92/gal while renewable diesel style economics approached $0.40/gal even with soybean oil above 74 cents/lb. The market increasingly views biofuel molecules as mandatory compliance barrels embedded inside the diesel pool rather than optional blending components.

Diesel Demand Trends

What makes the current setup unusual is that diesel demand itself now appears to be breaking under the weight of price. Weekly U.S. implied diesel demand swung from +257 kb/d above the 5-year average in late April to -228 kb/d below average in May. Yet at the same time, SONAR truckload spot rates surged to a record $3.69/mile, above even the COVID logistics peak. Consumer sentiment also collapsed to a fresh all-time low near 44.8.

Those numbers together suggest that the United States is not simply seeing weaker freight activity. Instead, the market appears to be entering a phase of diesel rationing through price. Freight continues moving, but transportation costs, fuel prices, and compliance costs are all compressing margins across the real economy.

Political Implications for Refiners

This is also where the RIN market becomes politically dangerous for refiners. Should D4 RINs extend toward $2.50, which increasingly looks possible under the current structure, the refining industry is likely to intensify pushback against the RVO system. Elevated diesel prices are already beginning to suppress consumption, yet obligated parties still need RINs to satisfy compliance requirements. In practice, lower fossil throughput can tighten the effective compliance burden further.

Vegetable Oil Market Dynamics

The broader vegetable oil market continues to reflect this structural shift. Jul26 soybean oil settled near 74.08 c/lb while Jul BOPO widened toward +497/mt and Jul BOGO surged toward +535/mt as gasoil corrected sharply lower. Bean oil expressed as a percentage of gasoil recovered to nearly 1.48 despite historically high global vegetable oil supply projections.

That remains one of the most important underlying themes in biofuels today. Global vegetable oil production is projected to reach another record high at 244.1 million tonnes in 2026/27, up 6.8 million tonnes from the current season. Soybean oil production alone is projected at 74.7 million tonnes while palm oil production is forecast above 81 million tonnes. Yet despite abundant feedstock projections, prices remain historically elevated because growth in renewable diesel, SAF, and marine decarbonization demand continues absorbing incremental supply.

Waste-Based Feedstock Challenges

The waste-based feedstock market also remains structurally tight. Industry estimates continue to place global collectible waste oil supply at only 12 to 24 million tonnes annually (large spread - am closer to 12 Mil depending on definition), while aviation and marine fuel mandates increasingly compete for the same feedstocks required by road biodiesel and HVO mandates. That helps explain why waste-based premiums in Europe remain historically elevated.

European biofuels remained resilient despite the sharp correction in ICE gasoil. ARAG June values were still indicated around $1408/mt for FAME 0, $1448/mt for RME, and $1563/mt for UCOME. Premiums over gasoil remained elevated near +$270 for FAME 0, +$310 for RME, and +$425 for UCOME. HVO values remained near $2868/mt flat price with premiums near +$1730 over gasoil. UCOME/FAME spreads remained near +$155 while HVO/UCOME spreads held above +$1300.

European paper activity also reflected continued defensive positioning. Q4 RME traded near +495 over gasoil while Q4 UCOME traded around +528. HVO Q4 remained around +$1730 despite liquidation pressure in the broader energy complex.

Agricultural Market Insights

Agricultural markets also remained firm into the Memorial Day weekend. Crude oil traded roughly 2.5% higher overnight as the Iran conflict entered its 12th week with the Strait still effectively closed and markets increasingly concerned about escalation risk over the long U.S. weekend. U.S. soybean export sales reached 12.9 million bushels versus trade expectations of 5.5 to 16.5 million bushels while China continued sourcing aggressively from both the United States and Brazil.

Conclusion: The Future of Biofuels

The broader message from the market is becoming increasingly difficult to ignore. Distillate backwardation, heating oil prices, and exploding RIN values all point toward continued scarcity in transport fuels even as diesel consumption begins to crack under the weight of elevated prices. The refining system is now being squeezed simultaneously by crude backwardation, compliance costs, and slowing end-user demand. That combination is precisely why renewable fuel economics continue strengthening despite record projected vegetable oil supply growth.
