Executive Summary FuelEU Index & Market Commentary | May 2026
May marked the first trading month following the close of the inaugural FuelEU compliance cycle, transitioning to early-cycle positioning for compliance year 2026. This shift was accompanied by a material decline in observed trade prices, with the market closing at 125.17 EUR/t CO₂e on 31 May and recording an average trade price of 152.93 EUR/t CO₂e for the month.
The decline reflects a combination of buyer optionality, seller-driven price concessions, and lower implied mitigation costs. Unlike the final weeks of the 2025 cycle, buyers are no longer operating under immediate compliance pressure and can afford to be selective. Sellers, particularly intermediaries, have responded by lowering price expectations to stimulate early liquidity.
At the same time, elevated fossil fuel prices, influenced by continued geopolitical pressure around the Strait of Hormuz, have narrowed the effective cost differential between fossil fuels and biofuels. This has reduced perceived surplus generation costs and contributed to downward pressure on surplus valuations.
Market Dynamics & Trends
May price action reflected the normalization of market conditions after the April compliance deadline. Following the closure of the 2025 trading period, urgency on the demand side declined sharply. Buyers entering the 2026 market now face a much longer execution horizon, with compliance obligations not requiring resolution until April 2027.
On the sell side, the softer early-cycle demand environment has led to increasingly defensive pricing. Sellers have started lowering offers to incentivize early transactions, a dynamic that appears particularly pronounced among intermediaries seeking to generate liquidity at the beginning of the new cycle. This has contributed to the sharp decline in the index through May, particularly toward month-end.
The macro-fuel environment has reinforced this downward move. Continued strength in fossil fuel prices has reduced the relative premium associated with switching to biofuels, thereby lowering implied surplus generation costs. Market participants have used this cost dynamic as a reference point to pressure surplus prices lower, even though the ability to benefit from such economics remains uneven across the market.
Demand-side behavior evolved over the course of the month. In the first half of May, activity was limited and largely characterized by price discovery, with buyers testing the market rather than committing meaningful volumes. In the second half, overall transaction activity increased as buyers began to recognize the relative attractiveness of current pricing levels with larger-volume transactions closing even below 125.17 EUR/t CO₂e.
