Situation

The Strait of Hormuz is operating under severe disruption. Reuters reports that shipping through the strait has slowed following tanker attacks, with US-Iran peace talks stalled and providing no near-term relief. Four outlets independently carry reporting on shipping traffic disruptions amid ongoing tensions, a convergence that strengthens confidence in the operational picture even where individual sources remain unverified or single-sourced. Port arrivals across the Hormuz-area ports on both the Persian Gulf and Gulf of Oman sides reached 779 vessels in the most recent 24 hours, a separate methodology from IMF PortWatch and not directly comparable to transit counts. PortWatch's most recently published daily figure, for 2026-08-09, recorded 1 vessel transiting the strait against a pre-crisis baseline of 73 per day; that count carries an expected multi-day lag as PortWatch publishes weekly on Tuesdays. As of 02:53 UTC, 428 vessels were holding position away from berth, and Brent crude stood at $89.16, up 0.28% over the preceding 24 hours. The Hormuz Index Crisis Pressure composite sits in the extreme band, flat over 24 hours, with physical transit deviation as the top contributor. The Escalation Forecast composite sits in the elevated band, also flat, with Polymarket escalation contracts as the top contributor. The two composites diverge in band, reflecting that current physical conditions are assessed as more severe than the forward expectation of further escalation.
