A tanker, a strike and a familiar lesson in the Strait of Hormuz

The Strait of Hormuz has a talent for reminding the world that a narrow waterway can carry an absurd amount of geopolitical weight. Early on Tuesday, a liquefied natural gas tanker travelling south off the coast of Oman was hit by an unknown projectile and caught fire on its port side, according to the British military and the United Kingdom Maritime Trade Operations centre. The vessel was near Limah, Oman, as it headed out of the strait toward the Gulf of Oman, which is to say it was doing what tankers do every day until politics gets in the way.

UKMTO said the strike caused a fire but no environmental impact, and that authorities were investigating. The details remain thin, which is often how these episodes begin: a flash, a blaze, a nervous statement, then a scramble for attribution. Iranian state television later offered its own version, saying a liquefied natural gas tanker had come under attack after ignoring warnings. It also suggested, through unnamed sources, that the ship was carrying natural gas from Qatar. Tehran, however, has made no official claim of responsibility.

That caution matters, even in a region where caution is usually in short supply. Iran’s joint military command warned last Thursday that all oil tankers moving through the strait must use routes approved by Tehran. Any failure to comply, deviation from the designated route, or disregard for the navigation protocols of the Islamic Republic of Iran in the Strait of Hormuz will be met with an immediate and forceful response from the armed forces, endangering the security of the violating vessels, the statement said. It also said interference by US forces in the strait will be met with a rapid and decisive reaction.

Behind the rhetoric sits a more practical dispute: who gets to control passage through one of the world’s most sensitive shipping lanes, and whether that control can be turned into revenue. Iran and the United States agreed in an interim deal to allow ships to pass without paying charges for 60 days, but Tehran insisted it should control vessel routes and later charge fees for passage, overturning decades of practice in the waterway. The United States and many Gulf Arab states say they will not accept Iranian tolls on transit, which is hardly surprising; the free movement of commerce tends to lose its charm once someone starts invoicing it.

The broader backdrop is no less awkward. Oman and a United Nations agency had earlier tried to launch a new route near Oman’s shore, an effort that was followed by attacks across the Middle East and exposed just how combustible the issue had become. For shipping companies, the lesson is not subtle. The route may be short, but the political bill keeps getting longer, and the Strait of Hormuz remains a place where trade, security and state ambition collide with unnerving regularity.
