Situation

The Strait of Hormuz remains the center of a contested operational picture: Iran has declared the strait closed and threatened to double the scale of strikes if the US attacks again, according to Islamic Invitation Turkey citing IRGC-linked sources, while the IRGC chief commander reinforced a revenge posture on Thursday, per Iranian state media Mehr News. The US and CENTCOM counter that vessels are still transiting, a position consistent with INTERTANKO reporting that southward tanker transits have fallen to single digits but have not ceased entirely, per gCaptain. This site's carrier-posture assessment is a cautious 'closed,' but the physical transit picture is genuinely contested and operators should not treat either declaration as definitive. PortWatch's most recent published figure, for 2026-07-05, recorded 34 transits against a pre-crisis baseline of 88 per day; separately, a scraper-derived 24-hour count of arrivals at Gulf ports shows 535 vessels, a different methodology tracking a different phenomenon. Brent shed -1.41% to $76.40 in the past 24 hours, a counterintuitive move the market is reading through a demand-destruction lens rather than a supply-shock lens, at least for now. The Hormuz Index Crisis Pressure composite sits at 88 (extreme), with war-risk insurance premiums its top contributor; the 30-day Escalation Forecast holds at 61 (high), its leading signal being Polymarket closure odds. The two readings diverge meaningfully: present conditions are extreme, but the forward market assigns only a high, not extreme, probability to further deterioration over the next month.
