  3. 03

Situation

The Strait of Hormuz remains under extreme operational stress. 19FortyFive reports the crisis is moving from bad to worse and characterizes the strait as effectively closed, though no major wire in this feed carries that assessment independently. Against that backdrop, CENTCOM says more than 1 billion barrels of crude have transited the strait under US military escort since the blockade began, a figure carried by Saudi Gazette, Middle East Monitor, and Anadolu Ajansı. Iran's military spokesman, per Mehr News Agency, dismissed both that total and CENTCOM's broader escort claims as fabricated lies. Middle East Eye separately reports the US military says Hormuz shipping volumes have reached a six-month high, though IMF PortWatch recorded only 8 transits on 2026-09-13, against a pre-crisis baseline of 85 per day, a multi-day lag that reflects PortWatch's weekly publication cycle. The Manila Times reports Iran struck an oil tanker in the strait, while abcnews.com and Central Oregon Daily report ships have been attacked there as fuel prices rise; neither claim has been independently attributed to an identified attacker in this feed. Brent crude stood at 103.87 dollars as of 23:50 UTC, down 0.21 percent over 24 hours; futures markets are closed and that figure is unchanged since the prior session's close. The site's 34 indexed events in the last 24 hours reflect sustained operational pressure across the waterway. As of 23:49 UTC, 410 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, flat over 24 hours, with physical transit deviation as its top contributor; the Escalation Forecast sits in the elevated band, flat over 24 hours, with the Brent-WTI forward spread as its top contributor.

Recorded

  • 435 vessels stranded away from berth
