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 across the past 24 hours is Iran's seven-day proposal: The Hill reports Iran has pitched a plan to restart US talks and reopen the strait within seven days if the US meets its conditions; BBC reports Iran has offered the US a deal to reopen the strait in seven days; AP News carries the same framing. The Hill also notes Trump is in no rush to respond. This proposal extends what was already on the record earlier in the day, when Iran linked any Hormuz reopening to US concessions including an end to the blockade and release of frozen assets. Iran's security chief, as previously reported, has said no step-by-step process exists and the strait stays closed until Tehran's full conditions are met, a position that sits in direct tension with the seven-day framing now circulating. Separately, the stock-index rally attributed to Hormuz reopening prospects was reported by outlets carrying that headline; the causal link between that equity move and the proposal is those outlets' framing, not this site's assessment. Brent stood at $104.37, down 2.20% over 24 hours, as of 23:55 UTC; futures markets are closed and that figure is unchanged since close. 126 events were indexed in the past 24 hours. As of 23:49 UTC, 429 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, easing over 24 hours, with the Brent-WTI forward spread as its top contributor.
