Why the EU Carbon Market Can Cut Auctions Even as EUA Prices Stay Near €80

How the Market Stability Reserve Turns a 1 Billion Allowance Surplus Into Fewer Auctions

The key point is simple: the EU carbon market does not cut auctions because the spot price is low. It cuts auctions because the Market Stability Reserve reacts to the total number of allowances in circulation, or TNAC.

When the surplus is above the MSR threshold of 1.096 billion allowances, the mechanism removes allowances from auctions and places them into the reserve. The European Commission has published the 2025 TNAC at 1,023,494,202 allowances, which is below that threshold but still very high. For the period from 1 September 2026 to 31 August 2027, 190,494,202 allowances will be placed in the MSR.

That matters because a market can look structurally oversupplied and still feel tight in practice. The primary supply can be compressed even while EUA prices stay near €80. In other words, fewer auctions do not automatically mean a quick price drop.

For buyers, the practical issue is auction supply compression. EEX has already published the 2026 auction calendar, and the lower volumes will be reflected in the calendars adopted around July 2026. The 2026 EUA volume is still in the hundreds of millions, but it will be adjusted by the MSR and by maritime quota effects.

That is why compliance desks and industrial buyers need to think about the primary market and the secondary market separately. Auction volume is the primary supply. Secondary market liquidity is something else. A buyer can face a tighter auction window even if trading liquidity in the secondary market remains usable.

The real question is not just how many allowances are missing from circulation. It is how much of the primary supply will actually be available in the months when buyers want to hedge. That is the bridge to the next issue: why a structural surplus does not automatically push EUA prices lower.

Why a Structural Oversupply Does Not Automatically Mean Lower EUA Prices

EUA prices are not driven by current supply alone. They are also driven by expectations about decarbonisation, abatement costs, fuel switching, and future policy constraints.

That is why a surplus on paper does not translate into a simple price line. The EU ETS is closer to a regulated scarcity market than to a classic commodity market. The MSR threshold, the removal of surplus allowances, and the way allowances return to the market all shape price formation.

For B2B buyers, the main risk is volatility of scarcity, not just the size of the surplus. The market can remain expensive because participants expect compliance demand to stay firm and because the forward curve already reflects future tightness.

A useful example is a large industrial group hedging 12 to 24 months ahead. It may still see EUA prices at elevated levels even when primary supply is being compressed. That happens because the market prices compliance demand, futures roll costs, and the credibility of the cap-and-trade path.

This is why terms like EUA price resilience, EU ETS forward curve, carbon market tightness, compliance hedging, and supply-demand imbalance are useful. They describe a market that is not pricing only today’s balance sheet. It is pricing future scarcity too.

That leads naturally to the industrial side of the story. If prices stay high and supply is squeezed, how do large emitters behave? BASF is a useful case for that.

What BASF’s Buyback Plans Reveal About Industrial Hedging and Carbon Cost Politics

BASF is a useful B2B case because large emitters do not look only at the spot price. They manage carbon exposure through buyback plans, procurement timing, hedging layers, and internal carbon budgeting.

The important signal is not that prices are low. It is that companies expect scarcity management and less elastic primary supply. That matters for chemical producers, cement, fertilisers, steel, and logistics-heavy manufacturing.

For industrial buyers, EUA exposure is an input cost risk. It is usually managed with purchase windows, exposure limits, and internal trigger prices. When auction supply is compressed, quarter-by-quarter planning becomes more important, not just annual budgeting.

This also becomes a governance issue. Buyback plans and position management can turn into carbon cost politics because they show how much margin can absorb carbon pricing and how much pressure exists to reduce the regulatory burden.

The broader lesson is that the market is not just sending a carbon price signal. It is sending a scarcity signal that is managed through policy. That matters for global buyers who need to think about procurement, supply, and cross-border strategy.

The Policy Signal for Global Buyers: Scarcity Management, Not Just Emissions Decline

The EU ETS is telling buyers that scarcity is being managed institutionally. Emissions reduction is the goal, but the market signal comes through active supply management, not through a simple linear fall in demand.

That makes the EU ETS a reference point for other carbon markets. The price is not only a cost signal. It is also a signal of regulatory credibility, capital allocation risk, and future cost pressure across the supply chain.

For procurement teams, the key point is that carbon cost does not depend only on actual emissions. It also depends on the auction design, the MSR, and future cap adjustments. That matters for cross-border carbon strategy, transfer pricing, and contract negotiation.

The distinction between emissions decline and scarcity signal is especially important for buyers trying to plan 2025 and 2026 costs. The market can become more expensive even if emissions are falling, because the policy framework keeps available supply tight for compliance and hedging.

Once that is clear, the next question is practical. What does this mean for 2025 to 2026 pricing, auction supply, and cross-border carbon strategy?

What This Means for 2025-2026 Pricing, Auction Supply, and Cross-Border Carbon Strategy

The 2026 auction calendars already point to a main EUA volume of about 408.2 million allowances, but the actual outcome will depend on MSR adjustments and later recalibrations.

The right way to think about pricing is as a range, not a single number. That range is shaped by auction compression, secondary market liquidity, compliance demand, and policy decisions on the MSR and allowance invalidation.

For buyers and treasury teams, the main risk is not only today’s price. It is the possibility that supply becomes tight at the wrong moment. That is what should shape hedge ratios, budget planning, and procurement timing.

Multinational companies should also align EUA procurement, reporting, and treasury management with other carbon-related tools. The EU ETS remains a reference point for carbon pricing architecture globally, so it affects how buyers think about carbon exposure across borders.

The takeaway is straightforward. The EU carbon market is not easing just because a surplus exists. It is managing scarcity in an institutional way, and that can keep prices elevated even if emissions growth slows.
