Situation
The Strait of Hormuz remains the focal point of an acute and contested crisis. Whether the waterway is physically closed or partially transiting is disputed: the IRGC says, per iranherald.com (unverified, single-source), that the strait will stay closed unless the U.S. accepts Iran's terms, while Iranian state media separately carries a claim from Iran's deputy foreign minister that no ship can pass without Tehran's coordination and that Iran will not move first on reopening. Neither claim has been independently corroborated. The most recent PortWatch published count, anchored to 2026-08-23, recorded 3 transits on that date against a pre-crisis baseline of 85 per day. Separately, our AIS tracking shows 386 vessels holding position away from berth as of 23:53 UTC. Brent stood at $89.68 at 23:53 UTC, up 1.79% over the preceding 24 hours; WTI was at $84.81. The Hormuz Crisis Pressure Index is in the extreme band, easing over 24 hours, with war-risk insurance acting as the single-component override that set the published composite. The Escalation Forecast sits in the elevated band, flat over the same period, with the Brent-WTI forward spread as the top contributor. The two indices diverge: state pressure is easing at the margin while the forward-looking forecast holds flat, signaling the market is not yet pricing a durable resolution. Six events were indexed in the past 24 hours. The BREAKING development, per CBC alone and not independently confirmed, is that the U.S. bombed targets in the strait and the IRGC has vowed retaliation.
