The winter arithmetic is getting the attention. The more revealing test comes on 1 January, when a ban Europe designed to be irreversible takes effect in the middle of a gas crunch it did not plan for.
Europe’s energy conversation this autumn is dominated by arithmetic. EU gas storage stands at roughly 70 per cent, about 12 points below the same point last year, and the Dutch TTF benchmark is trading around €72 per megawatt-hour, some €40 higher than before the United States and Israel struck Iran on 28 February. In Germany, which holds the continent’s largest storage capacity, sites are just over 57 per cent full, and Qatar has pushed its LNG force majeure out by another month. Last week Energy Commissioner Dan Jørgensen wrote to every capital urging them to keep curbing demand and to settle for an 80 per cent storage target rather than scramble for 90, describing what Europe faces as “a price crisis linking to a supply crisis.”
The numbers matter, but they are not the most revealing thing about Europe’s winter. That arrives on 1 January 2027, when the EU’s ban on Russian LNG imported under long-term contracts takes full effect: in the middle of the heating season, and in a market where analysts warn prices could breach €100 per megawatt-hour for the first time since the 2022 crisis. How Europe handles that date will say more about the durability of its break with Russia than any storage percentage. The circumstances around it also expose an uncomfortable truth about what four years of diversification have actually produced.
A ban designed not to bend

The regulation was built to survive precisely this kind of pressure. Rather than folding the gas phase-out into the sanctions regime, which must be renewed unanimously every six months and is exposed to any single member’s veto, the EU legislated it as a trade measure adopted by qualified majority. Twenty-four governments voted in favour, with Hungary and Slovakia against and Bulgaria abstaining. The design was deliberate: a ban that never comes up for renewal cannot be quietly bargained away in a bad month. Budapest understood this perfectly, which is why it took the regulation to the EU Court of Justice, arguing that an import prohibition is a sanction in disguise and should have required unanimity.
Brussels has also closed the side doors. When Hormuz first shut in March, Jørgensen ruled out reopening the ban, arguing that Europe could not indirectly finance Russia’s war. In June the Commission went further, clarifying that EU companies will not be permitted to buy, sell or ship Russian LNG anywhere in the world once the prohibition applies, even when the cargo is bound for customers outside the Union.
Yet the regulation contains a valve. If an emergency is declared and security of supply is seriously threatened in one or more member states, the Commission may suspend the import ban for up to four weeks. That clause, rather than repeal, is where this winter’s real contest is likely to be fought. Repeal would require new legislation and an open political fight in which the Commission has staked its credibility. A suspension requires only an emergency, and this winter emergencies may not be hard to declare.
Diversification that became concentration
The deeper problem is what Europe replaced Russian gas with. EU imports of American LNG rose almost fourfold between 2021 and 2025, so that the United States supplied 57 per cent of the bloc’s LNG last year. IEEFA now expects the US to provide two-thirds of Europe’s LNG in 2026 and to overtake Norway as the EU’s single largest gas supplier, even though American cargoes are, on average, the most expensive Europe buys. On top of that sits the EU’s pledge to purchase $750 billion of US energy. As early as January, before the Iran war began, Jørgensen was publicly arguing that Europe needed to diversify away from US LNG, citing Washington’s threats over Greenland as a warning sign.
The risk this concentration creates is not primarily coercion. American LNG is sold by private exporters on commercial terms, and it has kept Europe supplied through a crisis that would otherwise have been far worse. The risk is indifference. When Asian buyers pay more, US cargoes go to Asia, as they did this summer, precisely when Europe needed them to refill storage. A market relationship is not a security guarantee, and Europe’s gas security now rests heavily on a supplier whose cargoes follow price signals and whose government is a belligerent in the war that closed the Gulf’s main export route.
Qatar was supposed to be the hedge: a large, long-term supplier independent of both Moscow and Washington. It sits behind Hormuz. The result, as IEEFA noted in May, is that the Middle East war has left Europe more reliant on its two largest LNG suppliers, the United States and Russia, with European imports of Russian LNG reaching a quarterly record in the first three months of this year. Four years after resolving never again to depend on a single supplier, Europe has arrived at a different kind of concentration: on one partner’s market, on one adversary’s residual volumes, and on one chokepoint whose reopening depends on talks brokered by Pakistan, Oman and, increasingly, China, with no European capital among the principal intermediaries.
The case for bending, and the case against
The pressure to delay is real, and it is not confined to the Kremlin’s friends. The head of Spain’s Port of Bilbao, one of Europe’s largest LNG hubs, urged Brussels to reconsider the timing, warning that replacing Russian volumes too quickly would only deepen dependence on the US. Eni’s chief executive Claudio Descalzi called for the ban to be suspended, putting the imports at stake at around €20 billion. And the Commission has already shown that it will adjust its own timetable under market stress. In March it removed its planned proposal for a permanent ban on Russian oil from the legislative calendar, pointing to the turmoil created by the Iran war; by late June, the Baltic states were still pressing Brussels to bring it back.
The case against bending is equally concrete. The EU takes roughly three-quarters or more of the output of Russia’s Arctic Yamal LNG project, which means the ban strikes directly at a revenue stream for which Europe is the dominant customer; replacing those volumes means finding around 15 million tonnes elsewhere in 2027. A suspension, once used, would also establish that Europe’s most carefully insulated energy measure yields to price pressure, which is exactly the lesson Moscow has spent four years trying to teach.
The politics are shifting in ways that complicate both camps. Viktor Orbán, the ban’s loudest opponent, lost power in a landslide in April. But his successor Péter Magyar’s government has set 2035 as its target for ending Russian energy dependence and is likely to seek exemptions as a landlocked state. Even governments elected partly on a pro-European mandate, in other words, are pricing in a slower exit than the one Brussels has legislated.
What the January test will measure
None of this means Europe is heading for a physical shortage. The Commission maintains there is no immediate risk to security of supply, and a mild winter or a reopening of Hormuz could ease the pressure quickly. But the January deadline will measure something storage figures cannot: whether Europe’s energy decoupling from Russia is a strategy that holds when it costs something, or a policy calibrated to good weather.
Three signals are worth watching. The first is the emergency valve. A single four-week suspension during a genuine cold snap would be defensible; sustained reliance on emergency derogations would amount to repeal by other means. The second is whether the shelved oil-ban proposal resurfaces before the year is out or slides quietly into 2027. The third is demand. Brussels is reportedly seeking powers to order electricity demand cuts in an energy emergency, a tacit admission that the only durable answer to supply concentration is needing less of what has to be imported.
For years, European strategic autonomy has been debated in the vocabulary of defence budgets and ammunition lines. This winter it will be tested somewhere less glamorous: in whether a trade regulation stays switched on through January, while the gas Europe needs instead waits on a strait it cannot open and a supplier it cannot command.
