TTF natural gas: Hormuz closure enters fourth month, ~20% of global LNG supply locked behind the blockade

The Strait of Hormuz closure is now in its 13th week, and the impact on global natural gas markets continues to deepen. What began as a military confrontation between Iran and the US-Israel coalition on February 28, 2026 has removed roughly one-fifth of global LNG supply from accessible markets — a supply shock that the International Energy Agency has described as unprecedented in scale and duration.

The toll on global LNG supply. The IEA's latest quarterly gas market report estimates that global LNG production declined by 8% year-on-year in March 2026, driven entirely by the sharp drop in exports from Qatar and the UAE. Approximately 80 million tonnes per annum of LNG capacity that normally transits the Strait of Hormuz is now effectively stranded behind the blockade. (FACT: Kpler vessel tracking data via Finnotia, March 2026) The IEA projects a cumulative loss of roughly 120 billion cubic metres of LNG supply between 2026 and 2030 as a direct consequence of the conflict. (FACT: IEA, April 2026)

The United States has partially filled the gap, exporting an estimated 17.9 Bcf/d of LNG in March 2026 — the second-highest monthly volume on record — with terminal utilization at 94% of maximum DOE-approved capacity. (FACT: EIA Short-Term Energy Outlook, May 2026) However, US export terminals are already running near full utilisation, limiting the potential for further ramp-up.

TTF price action: elevated but volatile. European natural gas futures closed around €49.8/MWh on May 20, retreating from a near six-week high above €53/MWh as renewed hopes for a US-Iran agreement briefly buoyed sentiment. (FACT: TradingEconomics, May 20, 2026) But the retreat was short-lived. Reports that Iran's Supreme Leader had rejected key US demands for nuclear dismantlement sent TTF back above €50/MWh within days. (FACT: TradingEconomics, May 22, 2026)

The forward curve tells a more concerning story. Argus Media reported that the summer 2026 TTF contract opened above €70/MWh on the day fresh damage to Qatar's Ras Laffan facility was confirmed, before easing intraday. (FACT: Argus Media, April 21, 2026) The fact that forward contracts — which are less susceptible to intraday headlines than spot — have repriced so aggressively signals that markets now view the supply disruption as structural rather than temporary. ICE TTF front-month had previously reached an intraday high of $23.62/MMBtu (~€75/MWh) in early March as the magnitude of the crisis became clear. (FACT: Natural Gas Intelligence, March 9, 2026)

Peace talks stall, strait remains shut. A fragile ceasefire took effect on April 8, but fundamental disagreements over the Strait of Hormuz shipping regime persist. US Secretary of State Marco Rubio noted "some encouraging signs" in mid-May, and Pakistani mediators have attempted to bridge differences between Washington and Tehran. However, Iranian negotiators have insisted on maintaining control over strait transit fees and have linked the reopening to a broader agreement on sanctions relief. The head of UAE state oil firm ADNOC has publicly warned that full oil and LNG flows through the strait may not resume before the first or second quarter of 2027. (FACT: Reuters, May 2026)

The structural damage is already done. Even under an optimistic reopening scenario, the damage to Qatar's Ras Laffan liquefaction infrastructure — 17% of its 77 Mt/yr capacity is offline with repair timelines of 3–5 years — means that a portion of global LNG supply is permanently lost for the foreseeable future. (FACT: QatarEnergy CEO via Reuters, March 2026) The IEA notes that this supply shock has delayed the anticipated global LNG expansion wave by at least two years, pushing the market from a projected glut into a potential deficit.
