EU Gas Could Hit €100/MWh in Harsh Winter as Storage Nears Five-Year Low
Analysts warn a cold 2026-27 heating season could push ICE Endex TTF front-month above €100/MWh, double current levels, with European inventories near five-year lows.
European gas prices could more than double if this winter proves cold, analysts told Montel on Tuesday (2026-07-14), pointing to storage inventories near five-year lows as the central vulnerability. ICE Endex TTF front-month was trading at €54.41 on Wednesday (2026-07-15), which means the analysts' bear case would carry the benchmark above €100/MWh.8
The same analysts told Montel that physical shortages remain unlikely even under a stress scenario. That distinction will not comfort power buyers when the price range under discussion spans €50/MWh, but it does suggest the system retains enough flexibility to balance through the market rather than enforced cuts.8
Storage fill is where the pressure concentrates. In May (2026-05), analysts told Montel that Europe could still reach an "adequate" 86% fill rate before winter, but only if the Strait of Hormuz, disrupted by the Iran conflict, reopened quickly. A reopening after July (2026-07) would send prices higher, they warned. With inventories still near five-year lows in mid-July (2026-07-14), that early optimism has not been borne out by injection data.2,8
LNG dependency leaves European buyers particularly exposed to Middle East supply disruption. Roughly 25% of Europe's total gas supply comes through LNG imports, according to Stifel analyst Chris Wheaton. Wood Mackenzie has separately concluded that an extended Iran conflict could have severe impacts on global LNG markets, with Atlantic Basin cargoes repriced as Asian and European buyers compete for available tonnage.5,3
Power markets would amplify any gas price surge. Italy's spot electricity price could reach EUR 320/MWh — more than double its May (2026-05-21) levels — if high gas prices coincide with a cold snap, analysts told Montel at the time. That assessment predates the current inventory shortfall. German power settled at €105.65 on Tuesday (2026-07-14), already pricing in elevated gas costs without any winter weather shock.1
Germany's power system showed how quickly these stresses compound during the 2025-26 winter. In the week of 2026-05-18, the country's available power margin fell to its lowest point of the season, with wind generation in the preceding October and November running roughly 25% below year-earlier levels, Bloomberg-compiled models showed. When cold coincides with low wind, gas-fired output absorbs the residual load and transmits gas price moves directly into clearing prices.4
European power had already repriced sharply before this summer. Prices hit multi-year highs in May (2026-05) on elevated commodity costs, carbon, and persistent low wind output, with analysts warning at the time that the record run was not expected to end soon.6
The head of a German research institute warned in April (2026-04-10) that European governments were failing to grasp the "structural consequences" of high gas prices, which would hit when storage must be replenished. The mid-July injection data has since given that view added weight.7
NBP UK gas settled at €46.20 on Tuesday (2026-07-14), holding at a discount to ICE Endex TTF front-month through the summer. The pace of European storage injection between now and October, and any change in Middle East supply flows, will determine how much of analysts' €100/MWh scenario gets priced into the heating-season forward curve before the market turns.8
