TTF Rises More Than 10% as Qatar Supply Cuts Deepen European Storage Shortfall
ICE Endex TTF front-month gas climbed more than 10% on Tuesday (2026-07-07) to €47.10 per megawatt-hour, reflecting sustained supply pressure that has accumulated since the Iran war began reshaping global LNG flows. Iranian retaliation against U.S.-Israeli strikes knocked out an estimated 17% of Qatar's LNG export capacity, and Doha suspended export operations on March 2 (2026-03-02).6,3
European storage has borne the visible cost. Inventories entered the 2026 injection season approximately 7.2 billion cubic metres below the prior year's level — a gap of around 17% — according to Timera Energy analysis published in mid-May (2026-05-19).4 TTF's near-term curve slipped into backwardation in response, structurally disincentivising storage fills by making near-month gas more expensive than forward delivery.
That backwardation has direct consequences for winter supply. Timera modelled that each 1 bcm shortfall in European storage at end-September carries approximately $0.40 per million British thermal units of upside into January 2027 TTF. Running an 80% fill constraint — the European Commission's target — shifts most scenarios short of the goal, widening the tail of high-price outcomes through the heating season.4
LNG makes up roughly a quarter of Europe's total gas supply, according to Stifel analyst Chris Wheaton, which means the Qatari disruption struck at a critical import pillar.5 Met Group, the Swiss energy trader, said in late May (2026-05-21) that the war had delayed — rather than eliminated — expectations for LNG oversupply, and that supply could still outpace demand over the coming years as new export capacity comes online globally.2
The nearest-term substitution has run through coal. In Japan, coal-fired generation rose 11.1% year on year in April while gas-fired output dropped 12.9% to 16,447 gigawatt-hours, Reuters reported citing Japanese Electricity Market figures.6 South Korea showed a sharper reversal: coal-fired power surged 39.7% year on year in April to 10,733 gigawatt-hours, the biggest annual increase since August 2019, while gas output fell 6.4%, Korea Power Exchange data showed.6
Early May (2026-05) data indicated the trend was accelerating. Coal-fired generation in Japan rose 18.3% and in South Korea 14.7% in the month's first ten days, while gas-fired output fell 23.4% and 12.2% respectively. DBX Commodities estimated May coal imports by Asian buyers outside China and India would rise 9.4% year on year to 31 million metric tons.6
The divergence in commodity prices tells the same story. Asian spot LNG has risen 62% from the start of the war through mid-May (2026-05-19) while the Newcastle physical coal benchmark — at $119.15 per tonne as of Tuesday (2026-07-07) — climbed 13% over the same period, according to Reuters.6 The price gap made coal an economically rational substitute in markets with flexible dispatch capacity, and the switch happened fast.
Wood Mackenzie analysts noted that energy security responses to the conflict are already delaying coal plant retirements across Asia and Europe, extending the asset lives of a generation fleet many utilities had earmarked for early closure.3 BIMCO data showed coal shipments to South Korea, Japan and the European Union surged 27% from a year earlier in the month through mid-May (2026-05-11).3
Gas demand globally has held up better than the most pessimistic early-war projections anticipated. Economies substituted at the margin rather than contracting sharply, and the coal switch absorbed significant volumes without triggering the broader economic dislocation some analysts feared when Hormuz transit risks first emerged.1
But the supply recovery underpinning Met Group's longer-term view has yet to materialise in the data that drives European winter pricing. JKM Asian LNG stood at $16.17 per million British thermal units as of Tuesday (2026-07-07), while the VIX volatility index rose 3.66% in the session. The next concrete signal will come from weekly AGSI+ European storage figures and any confirmation of Qatari infrastructure repair progress — the two variables that will set the tone for TTF's path from here through September.6,2
