Europe's Gas Bills Set to Climb as Storage Runs Low and Prices Soar

European wholesale natural gas prices have more than doubled since the start of the year, and households could soon see the effects on their energy bills. The benchmark Dutch TTF front-month contract traded above €66 per megawatt-hour on Tuesday, having touched €68 earlier in the day — a sharp contrast with the roughly €29/MWh recorded in early January.

The surge reflects mounting market anxiety that the Strait of Hormuz may stay shut through the winter, choking off a passage that normally handles nearly one-fifth of the world's liquefied natural gas trade. The timing is particularly awkward for the European Union, whose gas inventories are sitting at unusually depressed levels just before the heating season begins. Data from Gas Infrastructure Europe showed storage at 62.99% of capacity at the end of the gas day on August 24 — well below the five-year average of 79%.

Natasha Fielding, editorial manager covering gas, LNG, coal and biomass at Argus Media, said stocks are exceptionally low for this point in the year, with the last comparable shortfall occurring in 2021 before the previous major energy crunch. Among the larger economies, Germany's facilities were just half full, while the Netherlands had filled only 44.3% of its capacity.

Analysts warn that replenishing those stores may prove costly. Goldman Sachs researchers Samantha Dart and Laura Cyr argued that current price levels won't suffice for Europe to top up storage over the winter, and that if Middle Eastern energy exports recover only gradually through 2027, December 2026 contracts could need to exceed €100/MWh — more than double their €50/MWh baseline scenario. Oxford Economics separately noted that while the bloc now consumes roughly 15%-20% less gas than in 2021, running on leaner stockpiles would mean greater dependence on winter LNG shipments, putting Brussels in direct competition with Asian buyers. In a worst-case tightening, Oxford Economics suggested the EU might even have to pause portions of its embargo on Russian gas, which took effect in March 2026 and is due to cover all imports by the end of 2027. Russia still accounted for about 12.5% of the bloc's combined pipeline and LNG purchases last year.

For consumers, the pain will arrive at different speeds. A short-lived spike would have muted impact, but a sustained rally gradually seeps into household bills as supplier contracts expire and new purchases reflect higher market rates. Fielding noted that customers on variable tariffs will feel the pinch first, and that countries with more liberalised retail markets tend to transmit wholesale costs faster. According to Oxford Economics, full pass-through typically takes about six months across the EU, though markets dominated by long fixed-price deals — such as Germany and Austria — can take close to a year, while France, Italy and Spain may respond within a few months and the Netherlands almost instantly.

Italy stands out as the large economy most vulnerable to the shock, owing to its combination of quick price transmission and heavy reliance on gas — although, ironically, it currently boasts some of the continent's fullest storage sites. Much ultimately hinges on the weather: with gas remaining the backbone of European heating demand, a prolonged cold snap would drive consumption higher and could compound the squeeze, with Oxford Economics projecting that eurozone consumer energy costs might run as much as 15% above year-earlier levels in the fourth quarter.
