Europe Faces Worst Gas Storage in 15 Years as QatarEnergy Flows Collapse
EU inventories stand 12 percentage points below last year at a 15-year seasonal low after the Hormuz blockade cut Qatar's LNG exports 96%, with winter six weeks away.
ICE Endex TTF front-month gas hit €79.64 per megawatt-hour during September before retreating about 2.5% on Friday (2026-09-11), closing the week still 12.1% higher, as Wood Mackenzie on Thursday (2026-09-10) declared EU gas storage the worst in decades. EU sites held roughly 65% of capacity by that date — down more than 12 percentage points from the same point in 2025 and the lowest seasonal level since at least 2011, according to data cited by WoodMac.7,6
That storage gap traces to the near-shutdown of QatarEnergy's LNG exports since the U.S.-Israeli war with Iran began in late February 2026. Reuters reported shipments fell 96% over the following six months as the Strait of Hormuz blockade brought flows to an almost total halt. Before the conflict, Qatar was among Europe's anchor LNG suppliers.5
Physical damage compounded the trade disruption. Iranian missile strikes on QatarEnergy's Ras Laffan terminal eliminated roughly 17% of its export capacity, with Blockonomi citing data showing the Hormuz strait itself carries approximately 20% of global LNG transit. The closure redirected the supply squeeze simultaneously to Europe, Japan, and South Korea, all competing for the same pool of cargoes from Atlantic Basin and Australian sources.7
ICE Endex TTF front-month was priced near €79.51 per MWh on Sunday (2026-09-13), up more than 40% since September 1 (2026-09-01) and at levels last seen in early 2023. Britain's NBP front-month advanced 12.6% over the weekly period ending Friday (2026-09-11), according to Blockonomi. The September run suggests European spot markets have absorbed a significant portion of the supply shock into current valuations, though some traders see prices as having outrun near-term physical balances, with bearish positioning on TTF front-month reflecting skepticism that the blockade persists through the full injection season.7
The storage picture has recovered only partially. GIE data showed EU sites were only 57% full as of August 5 (2026-08-05), one of the weakest readings for that date on record. Aggressive injection buying since then has raised the fill rate to around 65-67%, but Standard Chartered Bank expects that pace to continue precisely because inventories remain so depressed, projecting prices will stay elevated across Europe as the urgency to rebuild stocks sustains buying, Wood Mackenzie's September 10 (2026-09-10) report noted.3,6
The injection recovery reflects demand destruction and spot purchasing, not restored QatarEnergy supply. That limits how far storage can recover before October, when injection season closes and draw-down begins in earnest.3
Senior Equinor executives warned in May (2026-05-24) that Europe faced a critical shortfall if Hormuz disruptions persisted another one to three months. Most of that window has now elapsed without resolution. A separate problem complicates the rebuild: GIE analysis from April (2026-04-09) flagged that low or negative summer-winter price spreads remove the commercial incentive to inject aggressively, meaning the market signal is working against storage builders at the exact moment physical need is greatest.2,1
David Lewis, senior research analyst at Wood Mackenzie, called the current situation "very risky." The description echoes language used during the 2022 European gas crisis, when Russian supply cuts drove TTF to record levels. This episode starts from a storage position already 12 percentage points below where Europe stood a year ago, before the Hormuz blockade added the Qatari supply layer on top of already-depleted inventories.4,3
The repair timeline at Ras Laffan and any diplomatic shift around the Hormuz closure are the next concrete supply signals. A storage fill rate still below 70% by early November, with temperatures falling and heating loads rising, leaves European gas buyers with limited capacity to absorb a prolonged cold spell without emergency demand curbs or another leg higher in ICE Endex TTF front-month.3,7
