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 in the current window is Trump's rejection of Iran's seven-day roadmap, which had proposed a phased reopening of the strait in exchange for sanctions relief and a halt to hostilities. NBC News and Modern Ghana report Trump publicly confirmed the rejection. Per Al Jazeera, relaying a claim from Iranian Foreign Minister Abbas Araghchi, Tehran says it is fully prepared for war after Washington rejected the seven-day plan. Brent stood at $106.31 as of 02:53 UTC, up 1.91% over 24 hours; CNBC reports the move followed Trump's rejection of the Iranian proposal. Ninety-seven events were indexed across the past 24 hours, reflecting sustained pressure across the diplomatic and military tracks. As of 02:49 UTC, 233 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.
