European gas prices hit four-month high as Middle East conflict threatens winter supply

European natural gas prices climbed to their highest level in four months on Monday as the deepening military confrontation between the United States and Iran raised the prospect of a second winter of tight supply and elevated costs for the continent's industry and households. The Dutch Title Transfer Facility (TTF) benchmark, the reference price for European gas trading, briefly pushed above €60 per megawatt hour (MWh) in early trading, a level last seen in the opening weeks of the conflict that erupted on 28 February. Prices later settled around €57/MWh, but the spike underscored how quickly the market reacts to any threat to the flow of liquefied natural gas (LNG) through the Strait of Hormuz.

Storage deficit widens as summer injection season progresses

The price surge comes at a critical moment for European gas infrastructure. According to data from Gas Infrastructure Europe, aggregate storage across the EU and the UK stood at roughly 54% of capacity in mid-July, a full ten percentage points below the 64% recorded at the same point in 2025. The European Commission's revised gas storage regulation, adopted in 2022, requires member states to reach 90% fill by 1 November each year, with an intermediate target of 80% by early autumn. Missing those milestones would force governments to consider costly interventions, from strategic purchases to demand-reduction mandates.

Andreas Schroeder, head of energy analytics at Independent Commodity Intelligence Services (ICIS), warned that the margin for error is narrowing. "A cold winter start would substantially increase the cost of meeting the EU's 80% storage target," he said. "While security of supply remains achievable, the cost of achieving it rises sharply." ICIS modelling suggests that if TTF prices remain near €60/MWh through the autumn, European buyers would need to pay roughly €54/MWh to attract sufficient LNG cargoes for restocking, rising to €60/MWh or higher should temperatures drop early. That calculation assumes normal weather; a repeat of the cold snap that gripped northern Europe in December 2022 would push the bill significantly higher.

Qatari LNG flows squeezed by Hormuz disruption

The immediate cause of the supply anxiety is the sharp drop in LNG shipments leaving the Persian Gulf. Since the US began its expanded aerial campaign and Iran responded with missile strikes on Bahrain and Kuwait, only 26 cargoes have managed to transit eastward through the Strait of Hormuz, according to ICIS vessel tracking. In a typical month, 90 to 100 cargoes make the passage, most of them Qatari volumes destined for Asian and European markets. Qatar, the world's second-largest LNG exporter after the United States, supplies roughly a quarter of Europe's imported gas. Any prolonged interruption forces European buyers to compete for alternative cargoes from the US, Algeria, or Norway, all of which are already operating near capacity.

The disruption has already prompted ICIS to cut its 2026 global LNG supply forecast from 441 million tonnes to 431 million tonnes, a reduction of 10 million tonnes that roughly equals the annual consumption of a medium-sized European economy such as Belgium or the Netherlands. The revision reflects not only the lost Qatari volumes but also the reluctance of shipping companies to charter vessels for Gulf loadings while the risk of missile or drone attacks remains elevated. Insurance premiums for transiting the strait have risen sharply, adding a further cost layer that ultimately feeds into delivered prices.

Oil market spillover adds to inflationary pressure

The gas market's nervousness spilled into crude oil on Sunday, when Brent futures briefly breached $90 a barrel for the first time since early June. The spike was short-lived; prices eased after Iranian state media reported that diplomatic exchanges with Washington, mediated by Oman and Switzerland, were continuing despite the weekend's strikes. Nevertheless, the episode reminded traders that the conflict retains the capacity to disrupt roughly 20% of global oil and liquefied gas supply that normally passes through Hormuz. Higher crude prices feed through to petrol, diesel and petrochemical feedstock costs, complicating the European Central Bank's efforts to bring inflation back to its 2% target. The ECB's latest monetary policy statement noted that energy price volatility remains a key upside risk to the inflation outlook.

Diplomatic channel still open but military tempo increases

Western diplomats insist that a negotiated de-escalation remains possible. The US has signalled willingness to revive discussions on a nuclear framework in exchange for sanctions relief, while Iran has so far limited its retaliation to missile strikes on US-aligned Gulf states rather than direct attacks on American forces or commercial shipping. However, the tempo of military operations has accelerated. US Central Command confirmed on Monday that B-2 stealth bombers had struck hardened targets in western Iran overnight, the first use of such assets since the campaign began. Iran's Revolutionary Guard Corps responded with a barrage of ballistic missiles aimed at Al Udeid air base in Qatar, though most were intercepted. Each exchange raises the probability of a miscalculation that could close the strait entirely, a scenario that would send European gas prices well beyond the €80/MWh peaks seen during the 2022 crisis.

UK and continental Europe equally exposed to global pricing

The price surge has reignited debate in London and Brussels about the limits of domestic energy policy. Jess Ralston, head of energy at the Energy and Climate Intelligence Unit, observed that the latest spike is "a reminder that whatever we do in the UK, it has no significant impact on the price we pay for gas. The reality is that we are tied to international markets and the volatility that has come twice in the past few years from war thousands of miles away." The UK, despite its North Sea production and growing renewable capacity, imports roughly half of its gas demand, much of it priced off TTF. Continental Europe, having largely replaced Russian pipeline gas with LNG since 2022, is even more dependent on seaborne cargoes priced at the global margin.

That dependence has structural implications. European governments have accelerated permitting for LNG regasification terminals, with Germany, Italy and the Netherlands adding floating units that collectively provide over 40 billion cubic metres per year of new import capacity. Yet infrastructure alone cannot solve a supply shortfall if the source regions are cut off. The European Commission's REPowerEU progress report, published last month, acknowledged that the bloc's 2027 target of 50 billion cubic metres of additional LNG imports assumes "unimpeded access to global markets", an assumption now being tested in real time.

Industrial demand destruction lingers as a structural risk

High gas prices have already reshaped European industry. Energy-intensive sectors, fertilisers, chemicals, steel, ceramics, have curtailed output or relocated production since 2022. Eurostat's industrial production index shows that German chemical output in the first quarter of 2026 remained 12% below its 2021 level, while Italian ceramics production was down 9%. A sustained period above €55/MWh would likely trigger further permanent closures, eroding the tax base and employment in regions that have already suffered deindustrialisation. Policymakers in Berlin, Paris and Rome are aware of the political cost but have few short-term levers beyond subsidies that distort market signals and strain fiscal rules.
