US-Iran War Sends FuelEU Abatement Price Negative

Why It Matters

Negative abatement prices signal a rare cost advantage for low‑carbon marine fuels, potentially reshaping shipowners' compliance strategies and influencing future EU emissions policy.

Key Takeaways

• FuelEU abatement price fell to -$25.8/t CO2e.
• ICE gasoil futures hit record $1,569.75/t.
• Biodiesel now cheaper than fossil MGO for compliance.
• Compliance surpluses trade at $203.5/t CO2e.
• Shipowners hesitant due to volatility and availability.

Pulse Analysis

The escalation of the US‑Iran conflict has sent crude and refined product markets into overdrive, with front‑month ICE gasoil futures soaring to a historic $1,569.75 per tonne. This surge narrowed the cost gap between traditional marine gasoil (MGO) and renewable alternatives, effectively wiping out the green premium that usually justifies biodiesel use. As a result, the FuelEU UCOME‑MGO abatement price slipped below zero, marking the first negative reading since the scheme’s inception in early 2025. Such price dynamics illustrate how geopolitical shocks can instantly alter the economics of maritime fuel compliance.

FuelEU Maritime, which mandates a 2 % reduction in greenhouse‑gas intensity for vessels operating in EU waters, relies on an emissions trading system to balance compliance costs. When the abatement price turns negative, shipowners can meet regulatory targets by simply switching to UCOME‑based blends, which become cheaper than buying compliance credits. This contrasts sharply with last year’s market, where many operators preferred purchasing over‑compliance credits generated from low‑cost bio‑LNG derived from manure. The current surplus price of roughly $203.5 per tonne CO₂e further incentivizes the use of biodiesel, as generating compliance in‑house now outperforms buying credits.

Nevertheless, the theoretical cost advantage has not translated into robust physical demand. Operators remain cautious, citing ongoing price volatility, uncertain war trajectories, and limited availability of marine‑grade biodiesel at secondary ports. Engine compatibility concerns also temper enthusiasm for higher‑blend or pure biodiesel usage. If the conflict stabilises and supply chains adapt, the negative abatement price could accelerate a shift toward greener fuels, prompting regulators to revisit the balance between market‑based compliance and direct fuel incentives. For now, the market watches closely, weighing short‑term risk against the long‑term goal of decarbonising the shipping sector.
