Iran hits second vessel in Strait of Hormuz as tanker fire highlights threat to oil traffic
A tanker fire and a separate attack blamed on Iran’s Revolutionary Guard in the Strait of Hormuz have raised fresh questions over how safely oil can move through the narrow waterway that carries a major share of global crude exports.
A tanker fire and a separate strike in the Strait of Hormuz overnight have underlined how vulnerable commercial crews and oil flows are in one of the world’s most important shipping corridors.
The United Kingdom Maritime Trade Operations agency said a tanker was hit by an unknown projectile in the Strait in the early hours of 18 September. The impact sparked a fire on board, which was later extinguished. All crew members were reported safe, and authorities opened an investigation into what hit the ship and who might be responsible.
In a separate report, information attributed to regional security sources said Iran’s Islamic Revolutionary Guard Corps attacked a commercial vessel in the same area with either a drone or an anti‑ship cruise missile. That strike also caused a fire that was brought under control. Another update described Iran striking a second vessel in the Strait, presenting the incident as an escalation in pressure on global oil shipments.
The descriptions line up on key details: geography, the involvement of the IRGC, and the use of a drone or missile that led to a fire. What isn’t clear yet is whether the different accounts refer to one vessel that came under attack more than once, or to two distinct ships hit in separate incidents.
For crews sailing through Hormuz, that distinction doesn’t change the core reality. Navigating the narrows between Iran and Oman now means accepting that a routine watch can quickly turn into emergency firefighting. Even when fires are contained and nobody is killed, the damage can put ships out of service and leave seafarers shaken.
For oil markets and governments, the incidents come in the worst possible place. The Strait of Hormuz carries a large share of globally traded oil and significant volumes of liquefied natural gas. Any pattern of attacks there can push up insurance costs, prompt owners to delay voyages while they reassess the risks, or force ships onto longer and more expensive routes.
The latest reports arrive against a backdrop of broader confrontation involving Iran and its rivals, and ongoing debates in Washington, European capitals and Gulf states about how far to go in protecting commercial traffic. Each successful strike on a civilian vessel, even if it avoids mass casualties, supports arguments that existing patrols and deterrence measures around Hormuz are not enough.
Iran has previously used drones, vessel seizures and close encounters in the Strait to signal that it can disrupt energy flows if it chooses. It doesn’t need to declare a blockade to change behaviour. A steady drumbeat of incidents can be enough to make shipowners and insurers think twice before sending a tanker through the bottleneck.
The clearest indicators of what happens next will be decisions by major shipping firms on routing, changes in war‑risk insurance premiums for Gulf voyages, and any announcement of new escort or patrol arrangements by the United States, European navies or regional states inside the Strait of Hormuz. Any public comment from Iran linking itself to these attacks or threatening further action would raise the stakes further.
