IEA Sees Global Gas Tightness Stretching Into 2027 on Hormuz Shock

Global LNG supply is set to fall 3% in 2026 — the steepest annual decline on record — and Europe's decade-low gas storage could keep the world market tight well into 2027, the International Energy Agency warned on Tuesday in its Global Gas Security Review 2026.

The number that frames the winter: Europe enters the heating season with the lowest gas storage levels in more than ten years. That single inventory position, the IEA said, could "substantially increase the need for injections to replenish inventories through summer 2027, which could extend global market tightness well into the coming year."

What knocked the market off balance?

The proximate cause is the Strait of Hormuz crisis. Despite years of strengthened interconnectivity between regional gas markets — expanded spot trading, more destination-flexible LNG cargoes — the disruption has hit gas markets in Europe and Asia hard, according to the IEA report.

The agency did not mince words about the scale of it. "The current Middle East crisis has dealt a major shock to global gas and LNG markets," the IEA said.

The mechanics are blunt. LNG loadings from Qatar and the United Arab Emirates tumbled by more than 60 billion cubic meters between March and October. New projects in North America and Africa, plus additional feedgas from legacy producers in Africa, Asia and Russia, only partly filled the hole.

How much of the gap did the rest of the world plug?

Producers outside the Persian Gulf stepped up, but not enough. Non-Gulf LNG production grew 14% year over year — more than 40 bcm between March and October — offsetting about two-thirds of the decline in Gulf deliveries.

Even so, global LNG production fell 6% over the period, a drop of roughly 20 bcm year over year.

With supply shrinking and winter approaching, Asia and Europe are now competing harder for the same spot cargoes. That competition has pushed regional benchmark LNG and gas prices to their highest levels since the 2022–2023 supply crisis.

How long does the disruption run?

The IEA's 2026 supply forecast of a 3% decline rests on one key assumption: that flows through the Strait of Hormuz remain largely disrupted at least until the end of 2026.

There's a hard datapoint behind that assumption. Last week, state-owned QatarEnergy extended the force majeure on LNG deliveries to most customers through the end of December 2026 — a signal from Doha that it expects disruption for at least the rest of the year.

The takeaway in plain terms: Qatar, the world's top LNG exporter, is telling buyers not to count on contracted volumes for another twelve months.

What's the watch item?

Summer 2027 injection demand. Europe can't avoid refilling storage once winter ends; the question is at what price, and against how much Asian competition for the same cargoes. The IEA's read is that the refill cycle itself becomes the mechanism that keeps the market tight — pressure that would ease only if Hormuz flows recover or non-Gulf supply accelerates beyond the current 14% growth rate.

Until one of those shifts, buyers on both continents are pricing a market where the biggest exporter is offline and inventories start low.
