Situation
The Strait of Hormuz remains effectively closed to commercial traffic, with IMF PortWatch recording 8 transits on 2026-09-13 against a pre-crisis baseline of 85 per day. The lead development is a possible diplomatic opening: The Malaysian Reserve reports Iran and Oman are close to agreement on a shipping corridor through the strait, though the background context notes that a prior meeting of Iran and Gulf states on a new shipping route was postponed with no new date set, and Iran has ruled out talks with Washington until its terms are met. The reported Iran-Oman corridor discussions are a new and distinct development from that postponed multilateral meeting, and no outlet in this feed reports a deal has been concluded. On the security side, Iranian state media claims the IRGC struck a Togo-flagged tanker it said was taking an unauthorized route through the strait; the claim originates with Iranian state media and no major wire in this feed carries independent reporting of the strike or its outcome. A separate report, carried by The Economic Times, says Iranian drones and a missile targeted a US-contracted vessel near the strait, with crew injured; that incident was reported in the prior brief and no new facts about it appear in this window. Brent stood at $104.07, down 1.40% over 24 hours, as of 23:50 UTC. Marine Insight cites IMO data showing 80 ship attacks have killed 20 seafarers since the conflict began. As of 23:49 UTC, 408 AIS-visible vessels were holding position away from berth in the Strait of Hormuz and Gulf watch box, a count that leaves out ships within 25km of a working port. On the Hormuz Index, Crisis Pressure, the state composite, sits in the extreme band, easing over 24 hours, with physical transit deviation as its top contributor; the Escalation Forecast sits in the elevated band, easing over 24 hours, with the Brent-WTI forward spread as its top contributor.
