Update: Iran shuts Strait of Hormuz to all vessels, says ships will be targeted

Iran has officially closed the Strait of Hormuz to all vessels and threatened to target any ship attempting to pass, following recent military strikes. This escalation poses a significant threat to global energy supply chains and oil prices.
Why it matters
The Strait of Hormuz is a vital global energy chokepoint; its closure could lead to severe economic instability and spikes in global oil and freight costs.
A formal closure order for the Strait of Hormuz, backed by an actual strike on two vessels, marks a major escalation with direct implications for roughly a fifth of global oil flows. This moves the conflict from threatened disruption to active interdiction of shipping, and should drive a spike in Brent and WTI alongside surging freight and insurance costs for tankers in the region.Risk assets should broadly come under pressure. Markets will focus on whether the closure proves enforceable and how long it persists, given the strait's importance to Gulf exporters and Asian buyers alike.
The framing emphasizes the 'escalation' and 'threat' to global markets, which is common in financial-political reporting.
