Situation
The Strait of Hormuz remains functionally closed on paper but shows fragile early signs of reopening: PortWatch's most recent published day (2026-06-14) recorded 0 transits against a pre-crisis baseline of 94 per day, yet scraper-derived 24-hour arrivals at Gulf ports reached 112 vessels under a different counting methodology. The two figures are not comparable but together sketch a picture of paralysis giving way to cautious movement. Brent crude jumped +6.19% to $84.36 in the past 24 hours, driven by reports from gCaptain that Iranian-linked tankers have reappeared on AIS and are heading out through the Gulf of Oman, which TankerTrackers called Iran's first crude exports in two months, per Mehr News. President Trump signed an interim deal with Iran, per gCaptain, though energy insiders cited in the same outlet remain skeptical about how quickly commercial transit can normalize. Iranian state media claims 11 Iranian ships broke through the US naval blockade, though that claim carries no independent corroboration. The Hormuz Index state composite sits at 92 (extreme), with physical transit deviation as its top driver; the 30-day forecast composite has slipped to 53 (elevated), down four points, with Polymarket closure odds as the leading input. The divergence between those two readings captures the market's core tension: present conditions remain extreme even as traders price in a resolution. With 462 vessels still anchored or stopped and barnacle-encrusted hulls requiring remediation before departure, any reopening timeline faces real operational friction.
