Europe Gas Storage at 36 Percent, Hormuz LNG Disruption Drives Summer Refill Cost to EUR 26 Billion

European natural gas prices fell on June 2 after having surged 6.7% the previous session when Iran suspended US peace talks. Dutch TTF futures were trading at EUR 47.73 per megawatt-hour on June 2, down 2.77% on the day, per ICE TTF data via TradingEconomics. The retreat provided only partial relief for European utilities racing to fill storage ahead of winter. TTF remains 32.32% above its year-ago level, per TradingEconomics, reflecting a structural supply gap that a single trading session cannot erase.

Europe Exits Winter With Historically Low Reserves

European gas inventories finished the 2025-2026 winter season at just 28% of total capacity, well below the five-year average of 41%, per Equinor analysis published in late May 2026. Individual country shortfalls are severe: the Netherlands finished winter at 5.8% full, Germany at approximately 20%, and France at approximately 27%. Storage has since recovered to roughly 35% to 37%, per the same Equinor analysis, but that level still trails the typical late-May level of around 50%. EU member states are required to target 80% to 90% storage capacity by early winter, leaving a gap of more than 40 percentage points to close in less than six months.

Ras Laffan's Blocked Cargoes Drive the Shortfall

The closure of the Strait of Hormuz since February 28, 2026, halted LNG exports from Qatar's Ras Laffan terminal, the world's largest LNG liquefaction facility, per EIA data. No laden LNG tankers crossed the strait between March 1 and at least late April 2026, per EIA data. Qatar's LNG flows account for approximately 10 billion cubic feet per day, or about 20% of global LNG trade, per EIA analysis. Ras Laffan is operated by QatarEnergy LNG, a subsidiary of state company QatarEnergy; TotalEnergies, Shell, and ExxonMobil each hold joint venture stakes in QatarEnergy LNG's liquefaction trains and have reported corresponding shortfalls in contracted offtake volumes.

JKM and TTF Prices Reflect Competing Demand for Scarce Cargoes

JKM, the S&P Global Platts benchmark for LNG spot cargoes delivered to Japan, South Korea, China, and Taiwan, was assessed at $18.30 per MMBtu as of May 29, 2026, up 50.56% year-over-year, per TradingEconomics. CME Henry Hub futures have fallen to approximately $2.80 per MMBtu, down about 9% from pre-war levels, per EIA data, as the conflict limited near-term US export opportunities. The resulting Henry Hub-to-JKM spread reached $15.50 per MMBtu on May 29, a premium that reflects Asia's scramble for replacement cargoes. Dutch TTF seasonal spreads have moved into negative territory near minus EUR 1.30 per megawatt-hour, per Equinor analysis, creating unusual market conditions that actively discourage utilities from injecting gas into storage during the critical summer refill window.

The EUR 26 Billion Storage Math

Europe's total working gas storage capacity is approximately 1,135 terawatt-hours, per European energy market data. At a current fill rate of roughly 36%, the continent holds approximately 409 terawatt-hours. Reaching the EU's 85% winter preparation benchmark requires procuring an additional 556 terawatt-hours by early autumn. At current TTF of EUR 47.73 per megawatt-hour, that procurement totals approximately EUR 26.5 billion. TTF at the comparable period a year ago was approximately EUR 36 per megawatt-hour; the same 556 terawatt-hours at last year's price would have cost roughly EUR 20 billion, meaning the Hormuz disruption is adding an estimated EUR 6.5 billion to Europe's summer gas bill compared to year-ago conditions.

Equinor Warning and the EUR 90 Risk Scenario

Equinor warned in late May 2026 that missing the EU's 80% storage target is a real risk if Hormuz disruptions continue for one to three more months, per Equinor analysis cited by NaturalNews. Analysts cited in the same report project TTF could surge toward EUR 90 per megawatt-hour under a prolonged supply disruption scenario. TradingEconomics projects TTF at approximately EUR 57.59 per megawatt-hour in 12 months, implying the market expects partial improvement but not full resolution. The US Department of Energy approved two incremental LNG export capacity increases to address the shortfall: 0.5 billion cubic feet per day at Plaquemines LNG and 0.1 billion cubic feet per day at Elba Island, per EIA data. Those additions represent roughly 6% of the 10 billion cubic feet per day gap left by the Hormuz closure.
