EU Gas Risks Doubling to EUR 100/MWh as Storage Sits Near Five-Year Lows
ICE Endex TTF front-month rose 2.34% on Monday to €58.85/MWh, extending gains as analysts put a cold-winter doubling scenario on the table with stocks at multi-year lows.
ICE Endex TTF front-month gas rose 2.34% to €58.85/MWh on Monday (2026-07-20), with analysts warning this week (week of 2026-07-13) that prices could double from current levels and top EUR 100/MWh if a harsh winter materialises against storage that sits around five-year lows.7
The doubling call did not require a physical shortage. Analysts told Montel that an outright supply crisis was considered unlikely, but that price spikes of that magnitude were plausible if the injection season closes with insufficient buffer and winter temperatures disappoint. European gas reserves were measured at 37% of capacity by HSBC in late May (2026-05-25), well below the five-year average of roughly 50% at that point in the season. The gap has not narrowed since.7,4
Competition for available LNG is making the refill harder. Centralised Asian economies — China, Vietnam and South Korea — have been outbidding European buyers for spot cargoes this summer, officials and analysts warned in Brussels in June (2026-06-22), with limited global supply making European restocking more expensive. JKM Asian LNG held at $21.02/MMBtu on Monday (2026-07-20), a level that erodes the incentive for flexible cargoes to swing westward without a substantially wider TTF premium.6
The most severe supply scenario centres on Qatar. If Middle East conflict results in a three-month halt to Qatari LNG exports through the Strait of Hormuz, analysts projected in May (2026-05-21) that ICE Endex TTF front-month could approach EUR 100/MWh, based on an average of forecasts compiled by Montel. Qatari volumes represent a meaningful share of Europe's import capacity, and the loss of three months of flows would stretch an already-thin inventory position heading into the heating season.1
Italy sits at the sharp end of the exposure. Analysts told Montel on Thursday (2026-05-21) that Italian spot power could reach EUR 320/MWh — more than double current levels — if sustained high gas prices coincided with a cold snap, given the country's heavy dependence on gas-fired generation. Even in a more moderate escalation scenario, Italian power prices could surge by as much as 44%, analysts had told Montel in the week of 2026-04-20.2,3
The diplomatic calendar offers little clarity. A senior analyst at XS.com noted on Tuesday (2026-06-02) that conflicting statements from Washington and Tehran were making it near-impossible to price the conflict's trajectory, with ceasefire speculation and escalation fears cycling through the news flow without resolution. BMI, a Fitch Solutions unit, described the US-Iran war on the same date as having produced "wide-ranging disruptions to the Middle East" with no timeline offered.5
Crude markets have partially discounted a negotiated outcome. ICE Brent crude front-month rose above $100 a barrel on Monday (2026-05-25) after US airstrikes on Iranian missile sites dashed hopes of a breakthrough, but has since pulled back to $88.96/bbl as of Monday (2026-07-20). Gas markets have held a steeper premium to pre-conflict levels, suggesting traders assign a higher probability that LNG disruption proves structural rather than transitory.4
Not all near-term signals point higher. Bearish positioning on NBP day-ahead and German baseload front-month reflects some caution that the current TTF strength is running ahead of short-term physical balances, with policy and near-term supply factors weighing on prompt prices. But those signals do not resolve the structural inventory deficit heading into winter.
UK retail prices have already moved in one direction. The cap on typical dual-fuel bills in Great Britain was forecast on Wednesday (2026-05-20) to increase by nearly 13%, adding approximately £209 annually to average household costs — a consequence of Hormuz-driven gas prices that took effect before TTF reached its current level.4
HFI Research argued as early as the week of 2026-05-18 that the market had reached a "point of no return," characterising the diplomatic process as "this endless loop of Charlie Brown and Lucy with the football." Storage recovery through the autumn refill window will be the test that settles whether that assessment holds. European inventories would typically need to reach 75-80% capacity by October to provide adequate winter cover; the pace of injection over the next six weeks — and the stability of Qatari flows — will determine whether analysts' EUR 100/MWh projections remain contingent or become the working assumption.4
