European Gas Stocks at Record Lows as TTF Settles Above EUR 63, Outpacing Earlier Cost Forecasts
With European stocks at record lows, TTF has surpassed the EUR 50/MWh level that forecasters said would add EUR 15bn to the continent's storage bill.
ICE Endex TTF front-month gas settled at EUR 63.41/MWh in Wednesday's (2026-08-19) European session, already past the EUR 50/MWh level that energy regulator Acer and Italian major Eni had separately warned would drive a sharp rise in Europe's winter preparation costs.2,4
Europe's gas stocks have fallen to record lows after the US-Israeli war on Iran squeezed global LNG supply, Reuters reported on August 6 (2026-08-06), with analysts drawing comparisons to the 2022 energy crisis. The injection season is past its midpoint. Fill rates have not recovered the ground lost since the conflict began.6
The Oxford Institute for Energy Studies estimated on Wednesday (2026-05-20) that Europe will need 6% more gas — roughly 6 billion cubic metres — in 2026 than in 2025 just to enter winter with comparable storage volumes, Montel reported. Weaker demand could narrow the gap, OIES said, without specifying by how much.1
The shortfall starts from a weak base. EU gas inventories stood at approximately 28% of capacity — around 314 TWh or 29 bcm — as of April 1, 2026, well below levels seen in the three preceding years, according to Gas Infrastructure Europe data.3
Acer had warned in April that refilling storage would cost Europe an extra EUR 15bn if prices reached EUR 50/MWh, citing intensified LNG competition with Asia and supply disruptions from the Iran war, Montel reported on Thursday (2026-04-23). At EUR 63.41/MWh, TTF is trading more than EUR 13 above that reference, meaning the actual cost overrun could exceed Acer's April estimate if prices hold through the remainder of the injection season.4
Eni's chief financial officer said on Friday (2026-05-15) that EU storage demand alone could push prices to EUR 50/MWh or higher, telling Montel that markets had underestimated the duration of the Iran war's supply impact. Those assessments now look like floor estimates.2
Asian demand is tightening competition for LNG cargoes. JKM, the Asian LNG spot benchmark, was priced at USD 22.08/MMBtu in Thursday's (2026-08-20) session, keeping Atlantic arbitrage economics firm and reducing the pull of European prices on global supply. Europe has regasification capacity of around 1,600 TWh per season, according to Gas Infrastructure Europe, but physical infrastructure is not the constraint when Asian buyers compete for the same cargoes.3
Earlier this year, a Montel analyst poll published on Friday (2026-04-17) projected European gas could average EUR 45/MWh in 2026 if the Strait of Hormuz reopened and Qatari LNG output resumed over the summer. The consensus in that poll anticipated a late-May reopening, implying a roughly three-month halt from the conflict's February 28 start, when shipping through a route carrying around 20% of global LNG flows was closed.5
TTF at EUR 63.41/MWh in Wednesday's (2026-08-19) close is more than EUR 18 above that full-year average scenario. Wood Mackenzie senior research analyst David Lewis called Europe's storage position a "very risky situation," Reuters reported on August 6 (2026-08-06).6,5
Gas Infrastructure Europe's analysis noted that low or negative summer-winter price spreads were failing to generate the signals needed to drive storage investment at the required pace. Capacity alone cannot fix that. Europe has around 1,131 TWh of total storage space per season. Physical capacity is not scarce. Commercial willingness to fill at EUR 63/MWh, against an uncertain winter demand outlook, is another matter.3
With the European injection window shortening and TTF already above where Acer calculated the EUR 15bn cost overrun would begin, the most direct catalyst for relief remains the Strait of Hormuz — and when Qatari LNG flows can return at a pace sufficient to shift the global supply balance before October spreads begin pricing winter demand.5,4
