Situation

The Strait of Hormuz is sustaining its most intense period of commercial disruption since the crisis began. PortWatch recorded 1 transit on 2026-08-09, against a pre-crisis baseline of 73 per day; that figure carries a multi-day lag, as PortWatch publishes weekly on Tuesdays. Separately, port arrivals across the Hormuz-area ports on both the Persian Gulf and Gulf of Oman sides reached 388 vessels in the most recent 24 hours, and 495 vessels were holding position away from berth as of 23:53 UTC. The UAE has accused Iran of striking an oil tanker in the strait, a claim carried by five independent outlets. Per gCaptain citing Reuters, Iran attacked an ADNOC vessel while it transited the strait, described as a third such incident against UAE-flagged assets within a week; The Hill also reports Iran attacked a third UAE tanker in that window. Per Fox News, a single-source and unverified report, CENTCOM says it has redirected over 60 ships in the strait. Brent crude stood at $88.52, up 1.81% over 24 hours, as of 23:53 UTC; futures are closed and that delta is a carried-forward pre-close reading, not a live signal. The Crisis Pressure composite is in the extreme band with physical transit deviation as the top contributor; the Escalation Forecast sits in the elevated band with a flat trajectory, its top contributor being Polymarket escalation contracts. The two composites diverge: current pressure is easing at the margin while the forward outlook holds firm, signaling that market and intelligence signals do not yet confirm de-escalation.
