Situation

The Strait of Hormuz remains effectively closed to commercial traffic, with IMF PortWatch recording 1 transit on 2026-09-20 against a pre-crisis baseline of 85 per day. The dominant development this window is a significant addition to Iran's seven-day reopening proposal: CBS News reports Iranian President Masoud Pezeshkian has said Iran would allow nuclear inspectors as part of the offer, a concession not previously attached to the plan in this feed. BBC and The Hill also carry the seven-day framework, with The Hill framing it as Iran pitching a plan to restart US-Iran talks alongside reopening the strait. What is new here is the nuclear-inspections element; the seven-day framework itself and Iran's conditions were reported in the prior brief. Iran's foreign minister provided additional detail on the mechanism, per Al Jazeera. The proposal remains an offer, not an agreement: Iran's security chief has said separately that the strait stays closed until Tehran's full conditions are met, and no US response has been reported in this window. A seafarer was killed on 2026-09-23 when projectiles struck the bulk carrier Cape Dao off Oman, per the background record. Brent stood at $104.37, down 2.20% over 24 hours, as of 02:46 UTC; futures markets are closed and that figure is unchanged since the prior close. As of 02:49 UTC, 422 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 its value set by physical transit deviation alone; the Escalation Forecast sits in the elevated band, flat over 24 hours, with the Brent-WTI forward spread as its top contributor.
