Key takeaway

EU carbon at about €81 a tonne adds fresh pressure on the clean spark spread.

EUA December carbon allowances broke €81/tonne on Monday 13 July for the first time since February, climbing from a flat €79.04 settlement on Friday 10 July to about €81.35 on a market-data snapshot around 13 July⁠¹. EUA is the EU Emissions Trading System allowance that gas- and coal-fired generators surrender for each tonne of carbon dioxide they burn, so its price feeds straight into the marginal cost of thermal power.

The climb extends an established run rather than opening a new one. EUA first cleared €80 on 25 June and settled €80.17 on 30 June, so the €81 print is the next leg up, not a break from range. Treat the exact 81.35 level with some caution: it rests on a dated snapshot rather than a confirmed exchange settle, while the €79.04 baseline of 10 July is firmer.

With gas firm at the same time, CCGT marginal cost rises from carbon and fuel together, compressing the clean spark spread further just as gas-fired plant picks up the load French nuclear has dropped. The same squeeze showed up on 9 July, when gas and carbon rose together and compressed Germany's clean spark spread rather than the France-Germany spread.

Deep Analysis

In plain English

Carbon allowances are permits that power plants and factories must buy for every tonne of CO2 they emit under the EU's Emissions Trading System. The EU controls how many permits reach the market each year, and factories bid against each other for the shrinking pool. The EU has a rule that automatically pulls spare permits off the market when there is a surplus, which has been squeezing supply for a while. On top of that, the same heatwave that curtailed French nuclear plants (see the FR-DE spread story) is pushing utilities to burn more gas for electricity, and gas-fired power needs more permits. Both effects pushed the price above €81 a tonne for the first time since February.

Deep Analysis

Root Causes

The EU ETS Market Stability Reserve automatically withdraws a share of unallocated allowances from auction whenever the surplus sits above a set threshold, which mechanically shrinks the pool of allowances available to buy even if nothing about underlying emissions changes.

That structural tightening is being amplified by short-term fuel switching: when nuclear output drops (as in the French curtailment) or heat lifts power demand, utilities lean harder on gas-fired generation, and each additional gas-fired megawatt-hour requires more allowances, adding demand on top of the MSR's supply squeeze.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: EUA traded near or above €100/tonne in early 2023 on a similar combination of MSR-driven supply tightening and gas-for-power fuel switching after the Ukraine invasion cut Russian pipeline flows, showing the mechanism connecting power-market stress to carbon prices is not new.

Counter-parallel: That 2023 peak unwound over the following year as gas prices fell and fuel switching reversed, so a €81 print on its own does not establish a durable floor; the 2023 precedent argues the current level is as likely to prove cyclical as structural.

Consensus view: ClearBlue Markets has pointed to the EU ETS Market Stability Reserve as the mechanical driver behind carbon's grind higher through 2026, arguing that scheduled allowance withdrawals are tightening free float faster than falling industrial demand can loosen it, which is consistent with EUA holding above €80 since 25 June and pushing to €81.35 by 13 July.

Counter-view: IEEFA has argued the MSR story is only half the picture, and that this specific leg higher is fuel-switching demand: the same heat and nuclear-curtailment episode pushing up power prices is forcing more gas-for-power generation, and each extra CCGT hour run buys allowances rather than just reflecting scarcer supply.

Key tension: Whether EUA's break above €81 reflects a structural supply squeeze that persists once the heatwave ends, or a temporary demand spike from summer fuel-switching that reverses once nuclear output normalises.

Different Perspectives

United States (Joint Maritime Information Center)

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

Korea Shipowners' Association

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
