Situation

The Strait of Hormuz is the site of active, contested disruption: Iran's IRGC has re-declared the waterway closed and is actively warning vessels off unauthorized routes, with Iranian state media reporting three oil tankers reversed course after IRGC naval warnings, and IRNA confirming that ships outside Iran-approved frameworks will receive no safety guarantees. The United States disputes a formal closure, with US officials reporting vessels still transiting and characterizing the situation as coercive harassment rather than a verified shutdown; the physical transit picture remains unresolved. The IMO has suspended its evacuation of stranded Gulf shipping after a merchant vessel was attacked in the Gulf of Oman, per gCaptain, compounding pressure on operators already weighing route alternatives. Quantitatively, IMF PortWatch's most recent published day, 2026-06-21, recorded only 5 transits against a pre-crisis baseline of 93 per day; separately, a scraper-derived 24-hour count of Gulf-port arrivals logged 372 vessels, though the two figures use different methodologies and cannot be directly compared. Brent's +2.00% 24-hour gain to $74.10 reflects trader anxiety over supply corridor risk. The site's Hormuz Index places current Crisis Pressure at 90, in the extreme band, while the 30-day Escalation Forecast sits at 73, in the high band, a divergence that signals stabilization is not priced into the forward outlook.
