Why the Strait of Hormuz matters

The Strait of Hormuz is best known as the world’s most critical oil chokepoint — around a fifth of global petroleum passes through it — but it also carries every container service calling the Persian Gulf hubs such as Jebel Ali, Dubai and Dammam. There is no maritime alternative for Gulf ports, so any tension in the strait translates directly into war-risk premiums, insurance costs and rerouting decisions for the region’s supply chains.
