EU Carbon Holds Near EUR 86/t but ETS Reform Uncertainty Keeps Q4 Bulls Sidelined
EUA prices have stalled near EUR 85/t as Commission ETS reform proposals suppress directional trading ahead of Q4.
The Dec-26 EUA contract stood at EUR 86.53/t as of Friday morning (2026-09-19), a reading market participants have increasingly treated as a near-term ceiling rather than support. With the European Commission's ETS reform proposals still unresolved, expectations for Q4 have coalesced around the EUR 85/t mark. Analyst consensus has turned bearish on the contract.
The inability to sustain a rally above that range showed on Monday (2026-09-07). Montel reported that the Dec-26 EUA reached EUR 85.34/t in early trading, a fresh six-week high, before pulling back through the session. Participants cited volatility in recent weeks and below-average trading volumes as reasons for the retreat. The fresh high attracted no follow-through buying.5
The reform overhang explains much of the hesitation. Reuters reported on 31 July (2026-07-31) that analysts at multiple research houses had cut their EUA price forecasts for 2026 and 2027 after the European Commission tabled proposals designed to reduce carbon compliance costs for European industry. The revisions were uniformly bearish in direction, reflecting expectations that any final reform package will ease allowance supply or soften the mechanism that restricts it.4
The mid-July price action made the reform sensitivity visible. The Dec-26 EUA fell 3% on Thursday (2026-07-16), dropping below EUR 80/t, as participants repositioned ahead of the Commission's full reform package due the following day. That the market sold off on anticipation, before seeing a single clause of the text, showed how deeply supply optionality around reform is already embedded in the forward curve.3
The specific lever traders are watching is the Market Stability Reserve. A senior analyst at Veyt told Montel on Wednesday (2026-05-20) that the ETS adjustment under consideration could cut carbon prices by roughly 13% over the following two years. The MSR currently reduces auction volumes by 24% when allowances in circulation exceed 833 million tonnes; any revision to that threshold or rate would immediately affect forward permit supply.1
LSEG had already revised its price outlook lower before the July proposals emerged. The data provider said on Thursday (2026-05-21) that it had cut its carbon price expectations after identifying growing pressure from European industry on the Commission to ease ETS compliance costs. Concerns about industrial competitiveness have repeatedly taken precedence over supply tightening during 2026, and that ordering has consistently eroded the bullish case throughout the year.2
The cross-market transmission runs through power. Higher EUA prices raise the marginal generation cost at gas-fired stations, feeding into German and UK wholesale electricity prices. A reform outcome that loosens allowance supply would reverse that transmission, compressing the carbon component of generation costs — relevant for power traders tracking carbon positions alongside forward power contracts.2
The Dec-26 EUA has oscillated between roughly EUR 80/t and EUR 87/t for much of the past two months. Below-average volumes in recent sessions suggest few participants are building directional exposure ahead of the Commission's final text. When the MSR adjustment details are published, they will set the supply framework that defines the Q4 range. Until then, EUR 85/t looks less like a target and more like a waiting room.5,1
