2026 Strait of Hormuz Crisis

Background

The 2026 Strait of Hormuz crisis began on 28 February 2026, when the US and Israel launched military operations against Iran, resulting in the closure of the Strait by Iran. Iranian forces began attacking and boarding merchant ships, and the IRGC declared the Strait closed to "unfriendly nations." From 19 March 2026, the US began an aerial and naval campaign to reopen the Strait. A US naval blockade of Iranian ports ran from 13 April to 29 May 2026. Ceasefire negotiations have been ongoing, with a Pakistan-brokered ceasefire providing a partial framework, but tensions have continued with sporadic strikes on commercial shipping.

Key details
  • Iran had previously threatened to close the Strait of Hormuz during nuclear standoffs (e.g., 2011–12), but the 2026 closure is the first actual implementation.
  • 46 verified attacks on international shipping had occurred in the Strait by early June 2026, with 14 confirmed seafarer fatalities.
  • The US described its strikes on tankers as "blockade enforcement" against vessels allegedly violating restrictions related to Iranian port access.
  • India imports approximately 81% of its crude oil requirements, and the Gulf region — much of it transiting the Strait — is a critical supply corridor.
