The surplus indicator that governs the Market Stability Reserve has dropped below its upper buffer for the first time since the mechanism was built, and the consequence is a far gentler reserve intake than the carbon market is used to. The 2025 total number of allowances in circulation came in at 1.023 billion, beneath the 1,096-million threshold, which means only 190.5 million EUAs will be siphoned from auctions over the twelve months from September. That is an intake rate of roughly 18.6 percent, calculated off the difference between the surplus and the 833-million floor rather than the headline 24 percent. The automatic drainer of length is, for the first time, working at part throttle.
That matters because it coincides with Brussels preparing to do the opposite to supply. The read here is that the EU ETS is entering its most consequential rewrite since 2023 with a supply story pulling in two directions at once, and the proposal Wopke Hoekstra has flagged as his immediate priority, due 15 July, will have to reconcile them in public.
Supply that tightens and loosens in the same breath
The €30 billion ETS Investment Booster that Ursula von der Leyen announced in March is to be funded by selling 400 million allowances, aimed at SME decarbonisation and industrial heat, with guaranteed access carved out for lower-income member states. Read against the reserve mechanics above, the framing of that volume as fresh supply does not entirely hold. A Commission official has clarified that the 400 million is drawn from the Free Allocation Buffer and the New Entrant Reserve, both of which already sit inside the cap.
On our reading, a large part of the Booster is rebranding rather than addition. The Free Allocation Buffer already holds north of 300 million allowances, a slice earmarked for the Innovation and Modernisation funds, which monetise them on the market, and the balance auctioned anyway. The CBAM phase-in pot, allowances once reserved for sectors now covered by the border levy, carries more than 200 million destined for the Innovation fund and the market. The New Entrant Reserve is the hardest to size but likely exceeds 300 million, of which roughly 200 million is due to transfer into the MSR and the remainder auctioned.
The genuinely new variable is timing. NER excess is only quantified at the close of a trading period, so absent the Booster those volumes would not have reached the market before 2031. Pulling them forward is the part of this package that actually moves the 2027 to 2030 forward curve. Layer on April’s proposal to halt the MSR invalidation mechanism, which from 1 January preserved the reserve at 400 million and cancelled the excess, and the picture sharpens: the two structural forces that quietly retired surplus, automatic high-rate intake and invalidation, are both being eased at once.
The benchmark revolt the Directive cannot answer
The political fight has crystallised around free allocation, and it is not one bloc but two. Czechia, Greece, Poland and Romania put their names to a paper calling for benchmarks to be frozen at 2025 levels. Days later Germany, France, Spain and Estonia signed a separate text demanding the Commission revisit the fallback benchmark methodology before 2027, warning that the current trajectory could close factories and push production outside the bloc. At the Competitiveness Council, Slovakia and Estonia lined up behind the freeze camp while France and Spain voiced open disappointment with the draft. Estonia, notably, has a foot in both papers.
The countervailing voices were just as clear. Denmark, Finland and the Netherlands defended the system against Italy’s call to suspend it outright, and Sweden held the orthodox line that members must live by rules they themselves wrote. The Commission’s answer was that it cannot move further than its current draft because the Directive prescribes the fallback methodology, and that anything more must wait for the 15 July revision. Benchmark adoption is expected by the end of June, the full proposal a fortnight later.
What the freeze advocates want and what the Commission has already conceded point the same way. The 11 May draft extends free allocation to indirect emissions across fourteen product benchmarks, lifting benchmark values and handing industry an estimated €4 billion of additional value to 2030, while still covering around 75 percent of emissions for free on average. Freezing benchmarks at 2025 levels on top of that would loosen effective scarcity further, precisely as the Booster and the reserve changes add supply. The competitiveness relief and the supply injections compound rather than offset.
The discretionary turn and the politics around it
Pull these threads together and the direction is unmistakable. Automatic intake is softening because the surplus has fallen into the threshold-effect band, invalidation is set to be paused, reserve volumes are being pulled forward, and free allocation is being widened by the indirect-emissions extension before any benchmark freeze is even debated. The read here is that supply governance is migrating from rule-bound automaticity toward case-by-case discretion, and that the cleanest version of the July proposal would do the opposite of what the current sequence implies: treat the reserve as a stabilisation and liquidity instrument rather than a one-way supply vacuum, calibrate the post-2030 reduction factor around market functioning, and sequence CBAM, benchmark tightening and free-allocation phase-out against real investment cycles rather than letting all three tighten in lockstep while enabling infrastructure lags. Whether the proposal delivers that integrated logic or simply adds another lever is the open question.
The competitiveness grievance driving the eastern members is real and structural. Carbon cost embedded in power is not evenly distributed; it bites hardest in coal-heavy systems where the marginal generator still sets the price, which is why Poland and its neighbours press for relief while lower-carbon grids defend the orthodoxy. That dispersion, more than the absolute EUA level, is what is fragmenting the Council.
Hoekstra has chosen to manage the file partly by reframing resistance to the system as a target of foreign information manipulation, casting the ETS as central to Europe’s energy security and citing an estimate of €46 billion in extra fossil import costs since the start of the Iran war. He has paired that with the headline defence of the system: emissions from covered power and industry down by roughly half against 2005, on track for a 62 percent cut by 2030, €38.8 billion raised in 2024 and more than €250 billion since launch. The political management of the file is now explicit, and it tells you the Commission expects the July package to be contested on legitimacy, not only on numbers.
What this means for the 2027–2030 curve
The signal for desks is that the EU ETS supply outlook is becoming more political and less mechanical, and that shift deserves a risk premium the forward curve has not fully priced. With the TNAC now inside the threshold-effect band, the MSR removes less surplus each year just as invalidation is paused and reserve volumes are pulled forward through the Booster. The mechanism designed to make supply self-correcting is being softened from three directions at once.
The non-obvious consequence is for length and its persistence. The headline cap still falls at 4.3 percent a year, which keeps the long-term scarcity narrative intact and supports the structural bull case. But the near-term surplus that the MSR was built to absorb looks stickier than the cap trajectory implies, because the absorption is weakening while injections accelerate. The practical effect is to flatten the front of the curve relative to where pure cap mechanics would put it, and to load more of the value into the back end where the reduction factor does the heavy lifting. Calendar spreads, not outright direction, are where this package shows up first.
For industry the read is more straightforward. The indirect-emissions extension plus any benchmark softening is a transfer of value toward incumbents in carbon-intensive systems, financed by the same cap that the Booster and reserve changes are loosening. Whether 15 July produces the integrated logic the system arguably needs, or simply bolts another discretionary lever onto an already crowded toolbox, is the question that will set the tone for compliance buyers planning their 2027 hedges. The base case, on our reading, is the latter, and counterparties should plan for a supply regime that is more political and less mechanical than the one they have hedged against for the past five years.
