Situation

The Strait of Hormuz and Bab el-Mandeb are now both under acute operational pressure. Houthi forces have seized the Red Sea port of Mocha, tightening their grip on Bab el-Mandeb and a key chokepoint for global shipping, per gCaptain, BBC News, and jpost.com, which also reports Iran directed the advance. Whether Iran targeted vessels in the strait directly remains a live dispute: BBC News and The Guardian report Iran targeted vessels near the Strait of Hormuz, while France 24, L'Orient Today, and Al-Monitor report likely oil slicks in the strait following strikes on U.S.-flagged tankers. The closure picture is contested: one aggregated report describes the strait as closed amid the U.S.-Iran conflict, but PortWatch's most recent published day, 2026-09-06, recorded 6 transits; the physical transit picture has not been resolved by either side. Separately, our AIS tracking shows 357 vessels holding position away from berth as of 23:56 UTC. The IRGC Navy claims to have struck and destroyed a U.S. unmanned surface vessel at the entrance to the strait, per Iranian state media; no independent corroboration has been published. Crisis Pressure sits in the extreme band, rising over 24 hours, with physical transit deviation as the top driver. The Escalation Forecast sits in the elevated band, also rising, led by the Brent-WTI forward spread. The two indices diverge in band, reflecting different measurement horizons. Brent closed the 24-hour window at $109.09, up +7.33%, as of 23:56 UTC.
