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 central diplomatic signal in this window comes from Iran's parliament speaker: Al Arabiya English reports Ghalibaf says the strait will remain closed until Iran's conditions are met, a position The Hindu also carries, quoting him that there will be no reopening until those conditions are satisfied. Separately, Hindustan Times reports Iran will not reopen the strait until US commitments are met. This is consistent with the background position attributed to Iranian state media, though the specific framing that the strait stays shut until Washington lifts the blockade, removes oil sanctions, and releases frozen assets adds no materially new condition to what the prior run carried. On the military side, khaama.com reports Tehran has warned that US ships in the Indian Ocean will be attacked if war resumes, a claim carried by two desks in this window. Iranian state media claimed an Orbiter reconnaissance drone was intercepted over the strait; that claim has not been independently corroborated. The Tribune and aninews.in each report, without independent corroboration, that US forces redirected 109 commercial vessels near the strait to enforce a blockade. Brent crude stood at $103.78, down 0.09 percent over 24 hours, as of 23:52 UTC. Fifty-three events were indexed in the last 24 hours. As of 23:49 UTC, 461 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
- 372 vessels stranded away from berth
