Key takeaway

The negative German spark now holds across sessions, and France's day-ahead discount has shrunk to €5.37/MWh.

TTF settled €62.4/MWh on Wednesday 22 July and held €61.9 into Thursday 23 July⁠¹, its highest since the US-Israel-Iran war began and up from €59.135 on 20 July. EUA carbon broke a fresh high of €83.20/tonne on 22 July⁠², up from €80.14 on 16 July. Both inputs the 20 July inversion turned on are still climbing.

German day-ahead had reached €156 on 16 July, and the spark turned briefly positive; a week on, gas and carbon have pushed back past it. At roughly 0.2 tonnes of CO2 per MWh, EUA at €83 alone adds about €16.6/MWh to a CCGT's marginal cost before the gas leg, so carbon, not gas alone, drives the inversion this week. The spark reverses only if German day-ahead rises to meet the gas-and-carbon stack, and the 21 to 23 July tape does not show it.

That same German gas-set stack compressed the France-Germany day-ahead spread to €5.37/MWh on 23 July, Germany clearing €117.65 against France's €112.28⁠³. On 30 June the spread held around €71.50 even after French output cuts; three weeks of gas-and-carbon strength have closed almost all of it. EDF's reactors are running, yet TTF at €62 plus EUA at €83 lifts the German marginal price above France's nuclear-set floor. The German stack, not the French fleet, sets continental clearing this week.

Deep Analysis

In plain English

European power stations that burn gas have to pay two separate costs: the gas itself, and a permit for every tonne of carbon dioxide they release, called an EUA (EU Allowance). The EU deliberately makes fewer of these permits available each year to push emissions down, so their price tends to rise over time regardless of what else is happening in energy markets. This week both costs, gas and carbon, hit fresh highs on the same day. Most coverage focuses on gas, driven by tension near the strait of Hormuz, a narrow shipping route for Middle Eastern oil and gas. But the carbon permit price is climbing for its own separate reason, a long-planned EU policy to squeeze supply, and that part of the story would keep pushing power costs up even if the Hormuz situation calmed down tomorrow.

Deep Analysis

Root Causes

The EU ETS cap contracts on a fixed annual schedule set by the Fit for 55 package, roughly 4.3% a year through the current phase, independent of any single week's gas news. That mechanical tightening means EUA has been drifting toward higher clearing levels across 2026 regardless of the Hormuz situation, and 22 July's fresh high sits on that pre-existing trend rather than being caused by the same shipping risk moving TTF.

The two legs are correlated in this instance mainly because both cleared on the same trading session under the same general risk-on tone, not because carbon markets are structurally exposed to a Gulf chokepoint. Treating the €83.20 print as confirmation of gas-driven contagion into carbon risks missing the cap-tightening trend that predates 20 July entirely.

What could happen next?

Meaning
EUA's contribution to negative spark economics is running on the ETS's own multi-year cap-reduction schedule, not on Hormuz shipping risk, so the two drivers can diverge even though they moved together this week.
Immediate · Reported
Consequence
A Hormuz de-escalation that brings TTF down would not automatically restore a positive spark spread if EUA continues climbing on its scheduled cap trajectory.
Medium term · Reported
Risk
Desks reading the spread as a pure gas-risk trade may be under-hedged against the carbon leg's independent structural rise.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The July 2019 seizure of the Stena Impero in the strait of Hormuz produced an immediate freight and war-risk premium on Gulf-transiting cargoes that peaked within days and then decayed over roughly six weeks as insurers repriced risk downward once no further seizures followed and transit volumes proved resilient.

Counter-parallel: The 2022 post-invasion European gas repricing shows the opposite pattern: TTF's initial spike did not decay on a similar timeline because the underlying supply loss, pipeline gas from Russia, was structural and permanent rather than a transient risk premium, so prices reset to a new higher range rather than reverting.

The open question for the current Hormuz premium is which pattern it follows: a 2019-style decay once shipping data confirms no closure, or a 2022-style structural reset if flows are genuinely disrupted rather than merely threatened.

For a German CCGT operator, EUA is not a background cost but roughly a third of marginal generating cost at current TTF levels, meaning the carbon leg alone can flip a plant from in-the-money to out-of-the-money without any change in the gas price at all. A trading desk reading the spread purely off TTF is missing that the ETS cap's own trajectory is now doing comparable work to shipping risk in setting the floor under German power costs.

Structurally, this decouples the spark spread's recovery path from Hormuz de-escalation alone: even a full resolution of the shipping risk narrative would leave the ETS cap's scheduled tightening in place, meaning the carbon leg's contribution to negative spark economics persists on a multi-year basis that a single geopolitical de-escalation cannot reverse.

Consensus view: The market reads this week's joint EUA/TTF highs as a single Hormuz-driven risk trade, since both cleared their session peaks on 22 July.

Set against that, the EU ETS's Market Stability Reserve has been withdrawing surplus allowances from auction since 2024 under the Fit for 55 linear reduction factor, tightening the permit supply on a schedule that runs independently of Hormuz shipping risk, so at least part of EUA's climb reflects that pre-existing mechanical trend rather than the same shock moving TTF.

Counter-view: The correlation may still be coincidental rather than structural: EUA's 22 July high tracks the same session as TTF's own peak, and a carbon price rising on a pre-set emissions cap alongside a gas price rising on tanker risk is two separate mechanisms producing one number that happens to move together, not one mechanism driving both.

The Oxford Institute for Energy Studies' Quarterly Gas Review, Issue 33 (16 July), adds a further complication on the gas side alone: weather is simultaneously driving renewables, hydro and temperature-related nuclear curtailments this cycle, making 'a clean read on gas more difficult' even before the carbon leg is considered, and OIES flags a Persian Gulf LNG supply recovery as 'back in doubt'.

Key tension: Whether the EUA leg is now doing independent work in setting German CCGT marginal cost, meaning a Hormuz de-escalation would leave the spark still negative, or whether the two legs remain correlated enough that a gas-side resolution unwinds both at once.

Spark stays negative, French edge erodes

TTF and EUA rising together for a second session makes the negative spark a standing condition, not a one-day print, and nearly erases France's day-ahead discount.

Led to

Carbon sits still as gas and power dive

TTF and EUA rose together on 22 July (ID:5233); by 27 July gas and power had both reversed sharply while carbon alone held flat, splitting the prior joint move.

Different Perspectives

French Football Federation

The FFF called an 11:00 CEST press conference for 28 July, at its Paris headquarters, following an extraordinary executive committee meeting, at which Zinedine Zidane is expected to be presented as head coach succeeding Didier Deschamps. As of this writing no communique confirms the appointment, contract length or start date.

Morocco

Morocco is pushing for the 2030 final at its Grand Stade Hassan II in Casablanca, a planned 115,000-seat venue that would be the world's largest football stadium on completion. The venue is contested by a Spanish petition for the Santiago Bernabeu, and FIFA has fixed neither the venue nor the tournament's proposed 64-team format.

FIFA

FIFA's first tournament report, published 27 July, itemises nearly 300,000 accredited personnel, 73,700 security staff and 300,000 square metres of custom-grown turf, with no revenue or cost figure attached. As a Swiss association answering to its own Congress rather than a treasury, FIFA has followed the same operational-before-financial sequence it used after Qatar 2022.

Javier Tebas / La Liga

La Liga president Javier Tebas said on 21 July that FIFA's system is rotten from the root and that Gianni Infantino's time as president has, in his words, concluded. Tebas has no vote in FIFA's process, so days after the IOC declined jurisdiction over a separate ethics complaint, he used the only instrument he has.

Mexico City government

Head of government Clara Brugada presented a closing report on 22 July crediting the tournament with 44 billion pesos of economic activity, 2,000-plus accelerated public works and 100,000 formal jobs in June alone. The city has not published the method behind that figure, and three other Mexican bodies count the same five weeks differently.

Town of Foxborough

Foxborough answered Kraft Group's June lawsuit on 7 July with a 61-page counterclaim, calling the stadium's owners 'a collection of multibillion-dollar corporations' trying to shift its $7.8 million security bill onto taxpayers. The town says its licensing power and its billing power run through the same board, and it wants the court to award its own costs too.
