Europe's Gas Storage Gap Leaves Industrial Buyers Exposed as LNG Costs Surge

European gas storage sat at 36.3% of capacity on May 16, according to AGSI data — 7.3 percentage points below the same date last year and the lowest seasonal level in recent memory. To hit the EU's 80% minimum target by November 1, operators need to inject 45.7 percentage points in under five months. That requires roughly 130 LNG cargoes per month, ten more than the 120-per-month pace achieved during the entire 2024 injection season, according to Spanish consultancy Tempos Energía. The shortfall has direct consequences for industrial users. Energy-intensive manufacturers in Germany and Italy are absorbing higher spot exposure on marginal volumes at a moment when TTF, the European benchmark, is trading between EUR44 and EUR49 per MWh — up sharply from year-ago levels. On May 15, TTF briefly touched EUR49, a five-week high. The price curve has flipped into backwardation, with summer contracts above winter, a configuration that discourages the very storage injections Europe needs. The root cause is the March 4 closure of the Strait of Hormuz. QatarEnergy declared force majeure the same day, removing Qatari LNG volumes that had accounted for 12-14% of EU imports. Those cargoes remain offline. Europe has compensated by pulling harder on U.S. LNG, which now accounts for roughly two-thirds of European LNG imports — up from 29% in the first quarter of 2025, per IEEFA data published last week. That reorientation has put European and Asian buyers in direct competition. The Japan Korea Marker jumped to $18.96 per MMBtu on May 19, a $2.46 premium over TTF, as Atlantic Basin cargoes were redirected westward. Europe is currently 19 percentage points below typical mid-May storage levels of 55%, according to European Commission historical data. Uniper, one of Europe's largest gas wholesalers, has secured 10 billion cubic metres of pipeline supply through an extended ConocoPhillips partnership. That contracted volume offers some insulation but does not cover the spot market exposure most industrial buyers face on incremental purchases. Industry groups Eurogas and IOGP called on May 13 for more flexibility in meeting EU storage targets, warning that rigid compliance requirements could distort summer markets. Existing rules allow a 10-point deviation from the 90% end-of-season target, with a further 5 points under adverse conditions — but even reaching the 80% floor now looks challenging. Tempos Energía describes June as the first pressure point, forecasting TTF between EUR52 and EUR62 per MWh if Hormuz remains closed. Australia's decision on May 16 against implementing LNG export controls removes one supply risk, but hurricane season begins June 1. Any disruption to U.S. Gulf Coast loadings would leave Europe without a spare supply cushion heading into the July-August injection window — the last realistic opportunity to close the gap before winter.
