Situation

The Strait of Hormuz remains under severe operational strain. PortWatch's most recent published day, 2026-08-16, recorded 1 transit against a pre-crisis baseline of 73 per day; the weekly publication cadence means this figure carries a multi-day lag and is not a real-time reading. Separately, port arrivals across the Hormuz-area ports on both the Persian Gulf and Gulf of Oman sides totaled 544 in the most recent 24 hours, a figure that counts port-area entry events and is not comparable to the PortWatch transit metric. As of 02:53 UTC, 446 hulls were holding position away from berth, and Brent stood at $93.79, up 2.09% over the prior 24 hours. The Hormuz Index Crisis Pressure composite sits in the extreme band, flat over the past 24 hours, with physical transit deviation as the leading contributor. The Escalation Forecast composite is in the elevated band, also flat, with Polymarket escalation contracts as the top driver; the divergence between an extreme present-state reading and a merely elevated forward outlook is worth monitoring. In the Gulf of Aden, gCaptain reports that six armed men boarded and seized a U.S.-sanctioned product tanker, diverting it toward Somalia, in what gCaptain describes as a second such hijacking. UKMTO separately reported a tanker boarded by six armed people and diverted toward Somalia. The regional piracy and seizure risk layer compounds existing Hormuz throughput constraints.
