EU Nations Back Storing Surplus ETS Permits, Raising Supply Overhang Risk for EUA
Member states sided with the Commission over Parliament on the market stability reserve, putting two materially different supply paths on the table for EUA Dec-rolling.
EU member states backed keeping surplus EU ETS allowances in the market stability reserve rather than cancelling them automatically once they exceed 400m, Montel reported on Wednesday (2026-09-16). The vote aligns national governments with the European Commission, which first proposed the change on Wednesday (2026-05-20). EUA Dec-rolling was priced at €86.38/tCO2 on Wednesday (2026-09-23).6,1
The divide between institutions shapes how much supply stays available to the market. Cancellation permanently removes permits from circulation. Holding them in the MSR keeps them on the books for possible future release — a stored buffer rather than an eliminated one. For anyone positioned in EUA Dec-rolling, those two outcomes produce materially different supply paths depending on which text eventually becomes law.6,1
The European Parliament's environment committee voted on Thursday (2026-09-10) to keep automatic cancellation of surplus allowances above 400m until 28 February 2027. An interim position. MEPs went further on Tuesday (2026-09-15), backing continued cancellation of the surplus beyond 400m until the same end-of-February deadline while also supporting an increase in the threshold. Parliament is trying to preserve the cancellation mechanism; the Council wants to suspend it.4,5
Under the Commission's proposal, surplus allowances would be retained rather than destroyed. The practical effect on the cap: the cumulative supply overhang stays larger than under the existing mechanism if the surplus keeps building above the 400m level.1
The Parliament's interim position runs only until 28 February 2027 — a holding measure, not a final law. National governments have signalled a preference for the softer approach. Trilogue bargaining will settle which text survives, and the existing arrangement must be resolved before it expires.4,6
A second element sits inside the same file. EU nations also backed 121m extra free ETS permits for industry, Montel reported on Wednesday (2026-09-16). Free allocation on top of a larger stored surplus makes the near-term supply picture heavier than the Parliament's version implies.6
None of this has moved EUA Dec-rolling in an obvious direction. The consensus signal on EUAs is genuinely unclear, with bullish and bearish weights both at zero in available market data. A market handed a binary institutional fight over future supply, and yet to reprice it, is typically waiting for the final text rather than reacting to interim votes.5,6
The wider carbon policy queue is also lengthening. The Commission is weighing an expansion of carbon pricing to transport and heating fuels under ETS2, a cap designed to cut emissions 42% by 2030 versus 2005 levels, with ten member states warning about the cost to households. Separately, EEX has confirmed it will stop auctioning allowances for the REPowerEU programme once the €20bn target is hit — an auction supply change that feeds the same supply-demand arithmetic, though on a different timeline.3,2
Three institutions, three different versions of the same 400m threshold. If national governments prevail in trilogue, the market faces a persistent stored overhang and a smaller cancellation channel. If Parliament holds its line, the existing cancellation mechanism survives at least until 28 February 2027. The trilogue outcome, not the next interim vote, is the number that settles which path prices eventually have to discount.4,61
