Germany's anchor storage estate flipped to hard net injection in late June, 1,207 GWh/day with zero withdrawal, as EU refill surged past 3,700 GWh/day once the heat broke. The cheap TTF filling the caverns now, EUR 40 to 44, is a product of the same Hormuz oscillation that knocked out the assumption of an autumn Gulf reopening. Near-term injection and the winter supply outlook are pulling apart.
Cheap TTF enables record injection and erodes the autumn supply assumption at the same time.
Germany pushed 1,207.5 GWh/day into storage on 27 June with zero withdrawal, its hardest net injection of the season, lifting national fill to 41.21% with no state mandate behind it.
Germany's gas storage sites injected 1,207.5 gigawatt-hours on 27 June, the first day this season with zero net withdrawal. Fill rose to 41.21% by 28 June, with no government mandate driving the move.
Europe's benchmark gas price had fallen to €40-44 per megawatt-hour. That gave power plants and storage operators enough room to buy gas at the same time without competing for the same supply.
TTF round-tripped from a EUR 43.6 two-week high to a EUR 40.6 two-month low and back to EUR 43.62 over 27-30 June, yet still closed the quarter down more than 14%.
United StatesEuropean gas prices swung from €43.6 to €40.6 then back to €43.62 per megawatt-hour over four days. The move tracked Hormuz headline news. The quarter ended down more than 14%.
Oil prices rose just 1.3% on the same Hormuz stand-down news. European gas moved seven times as far, confirming Hormuz hits the gas market harder than the oil market at current supply levels.
EU net injection jumped to 3,721 GWh/day on 27 June after the late-June heat broke, lifting aggregate fill to 48.62% and clearing the November-floor pace by 29%.
EU gas storage injected 3,721 gigawatt-hours net on 27 June, the highest daily rate of the post-heat rebound. Aggregate fill rose from 47.97% to 48.62% over two days.
That pace cleared the required daily floor by 29%. There is still 354 terawatt-hours of gas needed before November, and autumn delivery via Persian Gulf routes is now the binding variable.
OIES charted EU storage to 74.3 bcm by 1 November on a mid-year Hormuz reopening; the 26-29 June Gulf round-trip knocked that base case out, leaving its stress case as the live path.
United StatesThe Oxford Institute for Energy Studies had forecast EU gas storage reaching 69.6% full by 1 November, based on a Hormuz reopening. The 26-29 June escalation broke that assumption.
The institute's stress scenario, with Hormuz closed through October, now tracks the most likely November trajectory. Europe needs 2.1 billion cubic metres per month of liquefied gas that the closed corridor is not providing.
Germany's day-ahead power cleared EUR 195.00/MWh for 30 June, a 2026 high for the date, as the year's lowest wind week collided with a summer heat surge.
Germany's electricity price hit €195 per megawatt-hour on 30 June. Wind output had fallen to its lowest of 2026, leaving gas power plants to set the market-clearing price.
Gas power stations set the price whenever renewables drop out of the stack. At €195, German industrial users paid more than four times the concurrent French electricity price across the same interconnected market.
JKM fell to near USD 11.1/MMBtu by late June, level with TTF, yet QatarEnergy's two destroyed LNG trains stay offline until mid-July at the earliest, capping any Gulf cargo recovery.
Asian and European gas prices converged to near-equal levels by 30 June, removing any financial incentive for gas tankers to divert to Europe. Two Qatar production facilities remained offline after missile strikes.
Even with European prices briefly the higher of the two, no cargo actually rerouted. Qatari supply damage capped any physical recovery regardless of where prices pointed.
France cleared EUR 123.50/MWh on 30 June against a far dearer Germany, an FR-DE spread of EUR 71.50 that held even as EDF curtailed 12% of its nuclear fleet.
France's electricity cleared at €123.50 per megawatt-hour on 30 June, €71.50 below Germany's €195. France's state power company cut 12% of nuclear output on river-temperature limits, but France stayed cheaper.
The nuclear cuts removed generation volume but Left enough low-cost reactors running to keep France below Germany's gas-set price. The spread holds unless river temperatures force deeper curtailments.
Germany's clean spark spread reached roughly EUR 74/MWh on 30 June, reversing a three-week run of losses, as EUA carbon held the EUR 80 handle at EUR 80.17.
Gas power plants in Germany earned about €74 per megawatt-hour gross on 30 June, reversing three weeks of losses. EU carbon permits recovered to €80.17 per tonne after briefly slipping below €80.
Three weeks earlier those same plants were losing €8-9 per megawatt-hour. The €83 swing in margins over three weeks came almost entirely from the electricity price rising, while gas and carbon costs barely moved.
Sideways on the storage-physical balance through July, with escalation risk concentrated in the October top-up window. The EU stood at 48.62% fill on 28 June with 354.8 TWh of capacity still needed before the 80% November floor; on OIES's closed-through-October stress trajectory that gap widens by 2.1 bcm per month of LNG shortfall, against a EUR 40-44 TTF that the OIES June Comment assessed as roughly EUR 6/MWh below the USD 20/MMBtu demand-choke threshold a closed corridor requires. Two named triggers determine direction: the 9 July Bundestag plenary second and third readings on StromVKG, which carries the 1 September capacity auction date and the Sudbonus siting premium contested at the 24 June hearing; and whether the 29 June verbal US-Iran stand-down holds long enough for QatarEnergy to begin physical restart of at least one of its two offline LNG trains before the August cargo-loading window for European September delivery closes.
