Strait of Hormuz Crisis Timeline

A dated timeline of the 2026 Strait of Hormuz crisis — military strikes, closures, diplomacy and oil-market moves — from the late-February onset through today.

This chronological record tracks 19 dated events in the 2026 Strait of Hormuz crisis, from the late-February onset (Feb 28, 2026) through the most recent development on Jun 2, 2026. The timeline spans 6 military, 5 maritime, 5 diplomatic developments — military strikes and tanker seizures, naval-blockade and diplomatic moves, oil-market shocks, and maritime disruptions such as shadow-fleet AIS-darkening. The most recent milestones are listed below; the full, severity-coded and exportable timeline is shown underneath.

Latest (Jun 2, 2026): ~94 days of paralysis; ~1,550 vessels stranded. Roughly three months into the closure, only a handful of ships transit daily (vs ~100 normal). About 1,550 commercial vessels (~22,500 mariners) are stranded in and around the Gulf, including six trapped Maersk ships. A 60-day reopening deal is reportedly close but not finalized.
