Tehran has signalled that any post-war settlement in the Gulf will leave Iran with a stronger role over the Strait of Hormuz, raising fresh uncertainty over shipping, energy flows and the fragile diplomacy aimed at ending the US-Israel conflict with Iran.
Mohammad Bagher Ghalibaf, Iran’s chief negotiator and parliamentary speaker, said on Tuesday that the waterway “will never return to its pre-war conditions” and would be administered by the Islamic Republic. His remarks placed one of the world’s most important maritime chokepoints at the centre of the emerging settlement, even as oil tanker movements through the route have begun to recover after weeks of severe disruption.
The statement amounted to a direct challenge to Washington’s insistence on unconditional freedom of navigation through the strait. It also sharpened questions over how any interim truce or broader diplomatic accord would be implemented at sea, where naval patrols, insurance rules, tanker safety and port access have become as politically sensitive as the nuclear and sanctions files.
The Strait of Hormuz links the Gulf with the Gulf of Oman and the Arabian Sea. It carried about 20 million barrels per day of crude oil, condensate and petroleum products in 2024, roughly a fifth of global petroleum liquids consumption. More than a fifth of global liquefied natural gas trade also passes through the same narrow corridor, with Qatar’s exports especially dependent on the route. China, Japan, South Korea and other Asian economies rely heavily on energy shipments that transit the strait, while Gulf producers have only limited alternatives for moving large volumes to market.
Ghalibaf’s comments followed several days of intense diplomatic activity after a preliminary US-Iran understanding sought to stabilise the military front, reopen maritime traffic and create space for further negotiations. Washington has temporarily eased restrictions on Iranian oil transactions for a 60-day period, while Tehran has indicated readiness to permit monitoring steps linked to its nuclear programme. The framework has not removed deep differences over sanctions relief, Israel’s security demands, missile capabilities and the future rules governing Gulf shipping.
Commercial traffic through Hormuz has shown tentative signs of revival. Several crude tankers and very large crude carriers have entered or crossed the strait after a sharp fall in traffic during the conflict, but flows remain below pre-war norms. Shipowners, insurers and energy traders are still assessing whether Iran’s proposed administrative role could introduce new fees, registration requirements or legal exposure for vessels using the passage.
Energy market reaction has been mixed. Prices eased after the first signs of diplomacy and partial reopening, but traders have continued to price in a risk premium because the waterway remains vulnerable to military miscalculation, mines, drone attacks and competing claims of authority. The International Energy Agency has warned that stability depends on full and unconditional access through Hormuz, arguing that partial access or politically conditioned movement would prolong volatility in oil and gas markets.
Iran’s position reflects a broader effort to convert wartime disruption into leverage at the negotiating table. Tehran has long argued that it has sovereign rights and security responsibilities in the Gulf, while the United States and its partners maintain that international shipping must not be subject to coercive controls. The dispute has gained greater urgency because the war exposed the limits of emergency rerouting and alternative export infrastructure, even among major producers with pipeline links outside the strait.
For Gulf economies, the stakes extend beyond crude prices. A prolonged shift in Hormuz rules could affect LNG contracts, marine insurance, port calls, freight costs and refinery supply chains. Higher risk premiums would feed into Asian import costs and complicate inflation management at a time when several central banks are already weighing the effects of energy volatility on growth and consumer prices.
