European natural gas prices have surged to levels far above where the year began, raising the prospect of higher household energy bills across the continent this winter. The benchmark Dutch front-month TTF contract traded above €66 per megawatt-hour on Tuesday, after touching €68 earlier in the session — more than double the roughly €29/MWh recorded at the start of 2026.
The rally reflects mounting market anxiety that the Strait of Hormuz will remain effectively closed into the heating season. The chokepoint normally carries nearly one-fifth of the world's liquefied natural gas trade, and its disruption has intensified competition for cargoes between European and Asian buyers.
The timing could hardly be worse. EU storage facilities stood at just under 63% full as of 24 August, according to Gas Infrastructure Europe, well below the five-year average of about 79%. Natasha Fielding, editorial manager for gas at Argus Media, noted that stocks have only been near these levels once in the past decade and a half — in 2021, just before the last major energy crunch. Among the larger economies, German stores were barely half full, while the Netherlands sat at roughly 44%.
Oxford Economics offered some reassurance in a report published earlier this month, noting that EU gas demand remains 15% to 20% below 2021 levels, meaning the bloc can limp through winter with lower reserves. The trade-off, however, is heavier reliance on spot LNG purchases — precisely the market where Asia's appetite could drive prices higher. Goldman Sachs analysts went further, warning that current prices are insufficient to refill storage and that December 2026 TTF contracts might need to top €100/MWh if Middle Eastern exports recover only gradually through 2027 — double their base case of €50/MWh.
Politics adds another wrinkle. The EU has legislated to phase out Russian pipeline gas and LNG from March 2026, with a full ban by the end of 2027, though Russia still accounted for around 12.5% of combined imports last year. Oxford Economics suggested Brussels could be forced to suspend parts of the prohibition if supplies tighten dramatically.
Consumers will not feel the pinch immediately. Wholesale spikes take time to filter through to retail bills because suppliers rely on hedges and long-term contracts. Households on variable tariffs will be hit first, particularly in liberalised markets such as the Netherlands, where pass-through is nearly instant, according to Fielding. On average, Oxford Economics estimates it takes about six months for wholesale moves to fully reach consumers, though fixed-price contracts in Germany and Austria can delay the impact by close to a year. It flagged Italy as the large economy most vulnerable, given its fast pass-through and heavy gas dependence — even though Italian storage levels are currently among Europe's highest.
Ultimately, weather may decide how painful the season becomes. With gas still the backbone of European home heating, Oxford Economics warned that a prolonged cold snap would stoke demand and prices alike, and estimated that eurozone consumer energy costs could run as much as 15% higher year-on-year in the fourth quarter.
