At least 13 commercial vessels altered course as disruption spread across the Persian Gulf, with Tehran's claimed reach extending from south of Mount Mobarak to Fujairah.
Iran's expanded zone also stretches from west of Qeshm Island to Umm al-Quwain, prompting ships to steer clear of the area.
The diversions highlight rising risks to one of the world's most important oil and trade chokepoints as maritime traffic faces growing uncertainty.

Dual Blockades in the Strait of Hormuz: Military Standoff and a 95% Drop in Vessel Traffic
Overview
In early 2026, following coordinated US and Israeli airstrikes that killed Iran's Supreme Leader, Iran established a de facto blockade of the Strait of Hormuz, a vital global oil passage. In response, the US imposed a naval blockade on Iranian ports and launched military operations to break Iran's control, leading to a sharp drop in vessel traffic to just 5-10% of normal levels. This dual blockade caused global oil prices to surge and disrupted key supply chains, including aluminum, chemicals, and fertilizers, while escalating military risks and diplomatic deadlock. The ongoing stalemate threatens prolonged economic pain and the risk of wider regional conflict, with no clear resolution in sight.
