Published by Techaroha | Market Analysis | March 20, 2026 | Carbon Markets Weekly 1. What Happened This Week: The Price Action in Context European carbon allowances entered the week of March 17–20, 2026 under considerable selling pressure. The EUA December 2026 contract, the most liquid benchmark contract on the Intercontinental Exchange (ICE), fell for the sixth time in seven sessions, eventually closing Friday at €66.65/tonne. This marks the lowest settlement since April 2025 and represents a cumulative decline of over 27% from the year’s intraday high of €92.04, reached on January 19, 2026.

To put this decline in historical context: EUA prices averaged €65/tonne in 2024 and had been forecast by institutions including ING Think to average €83/tonne across 2026 on the back of tightening supply. That bullish fundamental case has been overwhelmed, at least in the short term, by the political and regulatory uncertainty described in the sections below. 2. The EU Summit: Carbon Pricing in the Political Crossfire The March 19–20 European Council summit in Brussels was the single most consequential near-term catalyst for carbon prices this week. Although formally centred on the EU’s response to economic pressures from the ongoing Middle East conflict, the summit placed energy cost reduction and by extension the future of the ETS squarely on the agenda for EU heads of government. Commission President Ursula von der Leyen set the tone in a letter to summit participants in which she outlined measures to tackle rising energy costs across four pillars: electricity prices, network and grid charges, taxes and levies, and carbon costs. Critically, the letter signalled that the Commission would shortly adopt ETS benchmarks “taking into account concerns expressed by industry,” a phrase the market interpreted as a concession to lobbying pressure from carbon-intensive sectors. Von der Leyen also stated that the Commission would propose “to increase the firepower of the Market Stability Reserve (MSR), so that it can more effectively address excessive price volatility.” This was a double-edged signal: while a stronger MSR can support prices long-term by withdrawing allowances from circulation during surplus conditions, traders interpreted the language as opening the door for short-term price intervention, which depressed sentiment. 3. The 10-Country Letter: A Political Rebellion Against the ETS On Wednesday, March 18, the day before the summit opened, leaders of ten EU member states delivered a formal letter to the European Commission describing the current ETS framework as an “existential risk” for European strategic industries. The signatory countries were Austria, the Czech Republic, Croatia, Greece, Hungary, Italy, Poland, Romania, Slovakia, and one additional Eastern European state. Their demands were specific and far-reaching: The letter argued that energy-intensive industries, particularly those hardest to decarbonise (steel, cement, chemicals, glass), face a “perfect storm” of rising costs, unproven green technologies, and the accelerating loss of free carbon allowances that have historically shielded them from full ETS costs. Combined with energy prices elevated by the Middle East conflict and US tariffs constraining EU export competitiveness, the coalition argued the current framework threatens deindustrialisation. The political weight of this letter should not be underestimated. Ten member states collectively represent a blocking minority in EU Council procedures. Their coordinated action signals that ETS reform is no longer an industry lobbying campaign; it has entered the formal political process. This shift fundamentally changes the reform probability calculus for market participants. Industry and Academic Opposition to ETS Weakening The ten-country push has met significant institutional resistance. Bruegel, the Brussels-based economic think tank, published an analysis arguing that weakening the ETS would be “economic self-sabotage” on five grounds: This debate will directly shape the ETS Directive revision due in 2026 – the outcome of which represents the single largest structural risk (and opportunity) in the carbon market. 4. The Middle East Energy Crisis: Carbon’s Decoupling from Gas A critical and often misunderstood dynamic this week was the unusual decoupling of EUA prices from natural gas prices – a relationship that has historically been one of the strongest correlations in European energy markets. The ICE December 2026 Dutch TTF contract surged 40% between February 27 and March 3, driven by the escalating US-Israel military action against Iran and concerns about disruptions to LNG supply routes through the Strait of Hormuz. Normally, higher gas prices increase carbon demand: utilities switch to coal (higher emissions, needing more EUAs) and industrial producers face higher input costs, reducing output and triggering EUA purchases to cover compliance obligations. This time, however, the political overhang from ETS reform speculation was powerful enough to suppress the typical carbon-gas correlation. While gas spiked, EUAs remained under pressure, reflecting the market’s judgment that near-term reform risk outweighs fundamental supply-demand tightening. European gas storage levels compounded concerns, with storage at just 29% capacity on March 12 – well below seasonal averages and approaching the lows last seen during the 2022 energy crisis.

According to ICE Commitment of Traders (COT) data, investment funds held approximately 94 million allowances in long positions as of the week ending February
