20% Global LNG Supply Returns: Climate Reckoning as Qatar Restarts Exports

A peace deal that reopens the Strait of Hormuz could see Qatari LNG flood world markets, bringing price relief but reigniting the debate over gas’s role in the energy transition and whether abundant supply will delay investments in wind, solar and storage.

Qatar’s state owned LNG tanker Al Hamla sailed into the Persian Gulf and docked at the Ras Laffan export terminal on 18 June 2026, the first time an empty Qatari vessel has returned to the world’s largest LNG exporting complex since the Iran war shut the Strait of Hormuz in late February. The vessel’s reappearance – after going dark off western India a week before – is a concrete signal that the interim US‑Iran peace deal is translating into operational readiness and that Doha is moving to restart shipments that represent roughly one fifth of global LNG supply. QatarEnergy, the state producer, has told agencies it can bring unaffected liquefaction trains back to full capacity within a month, and Bloomberg reports the group aims to restore most of its export capability within two months of the waterway reopening.

Only a handful of tankers that turned off transponders – a high‑risk practice known as “going dark” – managed to move limited volumes with tacit Iranian approval.

The strategic chokepoint’s closure was the most disruptive shock to global gas markets since the 2022 Russian invasion of Ukraine. For nearly four months Qatari cargoes were either locked behind the Strait or forced to take cripplingly long alternative routes that were effectively blocked by Tehran’s military posture. Only a handful of tankers that turned off transponders – a high‑risk practice known as “going dark” – managed to move limited volumes with tacit Iranian approval. The supply shortfall drove Asian spot LNG prices sharply higher, forced European buyers to burn coal and compete for expensive Atlantic‑basin cargoes, and squeezed energy‑intensive industries from fertilizers to aluminium. With the Strait reopening, roughly 75 million tonnes per annum of effective production capacity is set to re‑enter the global balance.

Implications extend well beyond the immediate price relief. The return of Qatari LNG re‑establishes the traditional arbitrage between the Atlantic and Pacific basins, and the producer’s long‑term contracted volumes – many of which have been on force majeure – will resume flowing to clients in Japan, South Korea, China and India. Spot availability will increase, but the ramp‑up trajectory depends critically on two factors: the physical state of the Ras Laffan complex after strikes and the availability of empty tankers that had dispersed to safe anchorages. Al Hamla’s return, and reports that several other Qatari‑linked empty vessels began steaming toward the Gulf earlier in the week, suggests the tanker fleet is being reassembled. Shipping costs, which had rocketed for non‑Iran‑approved passages, will moderate as normality returns, though war‑risk insurance premiums will take time to unwind.
