Executive summary
- EUROMETAL reports that the European Parliament and EU governments have provisionally agreed to change the market stability reserve (MSR) of the EU Emissions Trading System. The Commission welcomed the deal on 21 October.
- Today, every allowance in the reserve above 400 million is cancelled. Under the deal, the reserve can keep up to 700 million as a buffer for later release. Cancellation above that level continues.
- The Commission had proposed in April to stop cancellations altogether. The co-legislators chose a higher ceiling instead, and left any later cuts to that ceiling to the wider ETS review proposed in July.
- For steel, a larger buffer gives the EU more allowances to release if carbon prices spike. That matters for mills as free allocation shrinks, and for importers, because the CBAM certificate price is set from ETS auction prices. Formal adoption is still needed.

What happened
The market stability reserve has run since 2019. It takes allowances out of auctions when too many are in circulation and puts them back when the market is short. Under the current rules, every allowance held in the reserve above 400 million is cancelled for good. By the end of 2024, 3.2 billion allowances had been cancelled this way, according to the Commission.
On 1 April 2026 the Commission proposed to stop those cancellations, so the allowances would stay in the reserve as a buffer against future shortages. Parliament and the Council have now agreed a narrower change. In its statement of 21 October, the Commission says the reserve will be able to keep up to 700 million allowances. EUROMETAL, reporting the Council’s announcement, says the deal was reached on 20 October and that cancellation above the new ceiling stays in place.

A wider reform of the reserve was proposed with the ETS review on 17 July 2026. EUROMETAL reports that a gradual lowering of the new ceiling will be dealt with in that review; we could not check this point against an official text. Parliament and the Council still have to adopt the amendment formally, and it takes effect once it is published in the Official Journal.
Why it matters for steel
Analysis Integrated steelmakers are among the largest buyers of EU allowances once free allocation runs out, and that free allocation is being reduced as CBAM takes over. A reserve that holds more allowances gives the system more to release if prices jump. It does not lower today’s carbon price, and it does not change the overall cap. What it changes is how much room the EU has to soften a future spike.
Analysis The same price feeds into imports. The Commission sets the CBAM certificate price as the weighted average of ETS auction clearing prices. It was €75.36 for Q1 2026, €75.28 for Q2 and €82.32 for Q3, so the cost an importer owes on embedded emissions in coil, plate or wire rod follows the ETS market. From 2027 the price will be published weekly instead of quarterly. A steadier ETS price makes the CBAM part of a landed-cost calculation, as in our worked example, easier to plan.
Analysis The change is modest. The Commission wanted to stop cancellations completely, and the co-legislators kept them. The bigger decisions on the reserve and on industrial carbon costs sit in the ETS review, which is still under negotiation.
Who is affected
- EU blast-furnace steelmakers: they hold the largest allowance exposure as free allocation shrinks, so the reserve’s capacity to calm price spikes matters most to them.
- Importers of CBAM steel: their certificate cost is set from ETS auction prices, quarterly in 2026 and weekly from 2027.
- Buyers of flat and long products: carbon costs show up in mill offers and in the CBAM cost on imported material.
Stay ahead of the steel market
What to watch
- Formal adoption: votes in Parliament and the Council, then publication in the Official Journal.
- The ETS review: whether it lowers the 700 million ceiling over time and how it treats free allocation for steel.
- 4 January 2027: the Commission’s Q4 2026 CBAM certificate price, the last quarterly figure before weekly pricing starts.
Verification status: Partially verified
- The agreement is reported by EUROMETAL. The threshold-lowering claim remains insufficiently attributed and is based on a single trade-press source. Last fact-check: 24 October 2026.
- Key: Verified = material factual claims are supported by an appropriate primary source or clearly attributed reporting/market assessments; Partially verified = a specific material claim remains unsupported, contradicted or materially overstated; Analysis = interpretation or forecast with sourced premises; Developing = material facts are checked but the situation is still changing.
