Why are Japanese-linked ships using an Iran-proximate route to exit the Strait of Hormuz, and what does this indicate about current transit conditions?

Japanese-linked ships—including eight vessels operated by Mitsui OSK Lines Ltd., such as five supertankers, two chemical tankers, and a car carrier—are using a route close to Iran to exit the Strait of Hormuz because they abandoned earlier attempts to cross via the US-managed route along Oman’s coast; Iran has asserted control over Hormuz since its interim peace deal with the US, declaring that only ships with its permission may transit, and these vessels switched routes to comply with that condition while seeking safe passage. This shift indicates that commercial operators are adapting to Iran’s de facto regulatory authority in the strait amid heightened geopolitical constraints and the absence of guaranteed security on alternative corridors.

What is the significance of these ships’ successful transit for the global oil market and the number of tankers previously trapped in the Persian Gulf?

If these vessels complete their crossing, the number of large oil tankers trapped in the Persian Gulf since the start of the war will fall from over 100 in early March to just a handful—marking a major reduction in logistical bottlenecks—and their movement contributes to a surge in oil supply that has already caused prices to slump and intensified market fears of a global glut, especially as the US–Iran peace deal enables renewed flows through Hormuz.

A convoy of Mitsui OSK Lines ships, including oil and chemical tankers, exits the Strait of Hormuz via an Iranian route amid safety concerns. This reduces trapped vessels significantly, influencing global oil supply expectations and prices following a US-Iran interim peace deal.
