Situation

The Strait of Hormuz remains under extreme operational stress as the Hormuz Index Crisis Pressure composite holds at 94 (extreme), with physical transit deviation the dominant driver; the 30-day Escalation Forecast sits at 62 (high), a divergence that reflects sustained present disruption against a forecast that does not yet price in full closure. PortWatch's most recent published day, 2026-05-31, recorded just 10 transits through the strait, a fraction of the pre-crisis baseline of 95 per day; scraper-derived 24h arrivals at Gulf ports registered 207 vessels under a different methodology and should not be read as contradicting that figure. Brent crude responded, trading at $97.41 on a +1.54% 24-hour move, as markets absorbed the IRGC's announced missile and drone strike on the US Fifth Fleet headquarters in Bahrain and Iran's formal condemnation of US attacks on an Iranian tanker and a Qeshm Island communications tower. The breaking development sharpening risk premiums is the IRGC's claim that a misfired US Patriot interceptor caused the Kuwait airport terminal destruction, a framing that, if accepted in regional capitals, extends liability and complicates US freedom-of-navigation efforts. Meanwhile, 292 vessels remain anchored or stopped in surrounding waters, 28 events were indexed in the past 24 hours, and Greek tanker owners are pre-positioning ships outside the Gulf in anticipation of a potential reopening premium.
