2026 Strait of Hormuz Crisis

Source: https://en.wikipedia.org/wiki/2026_Strait_of_Hormuz_crisis
Date: February 28, 2026 – present
Narrative Phase: Peak crisis (March–April 2026) → ongoing de-escalation (June 2026)

Summary

The Strait of Hormuz has been largely blocked by Iran since February 28, 2026, when the United States and Israel launched an air war against Iran following the assassination of Supreme Leader Ali Khamenei. Iran retaliated with missile and drone attacks on Israel, US military bases in the region, and US-allied Gulf states. The IRGC issued warnings forbidding passage, boarded and attacked merchant ships, and laid sea mines in the strait. From April 13 to May 29, 2026, the US simultaneously blockaded Iranian ports.

This closure constitutes the largest disruption to world energy supply since the 1970s energy crisis and the largest in the history of the world oil market.
