Situation

The Strait of Hormuz remains the central operational flashpoint of the regional crisis. Per Iranian state media, the Persian Gulf Strait Authority claims transit through the strait is suspended due to what Tehran describes as aggressive US military actions; that claim is unconfirmed by any independent maritime authority and must be treated as such. USNI News reports that traffic levels last week fell to their lowest point since March, with transits down 52.4 percent between July 20 and the most recent measurement period, per that outlet's figures. Separately, PortWatch's most recent published day, 2026-07-23, recorded 10 transits against a pre-crisis baseline of 88 per day. Port arrivals across the Hormuz-area ports on both the Persian Gulf and Gulf of Oman sides totalled 408 in the most recent 24 hours, a distinct metric that should not be read as a transit count. At 02:52 UTC, the anchored-or-stopped vessel count stood at 1,233, per our AIS tracking. The Crisis Pressure index sits in the extreme band, flat over 24 hours, with physical transit deviation as its top driver; the Escalation Forecast index is in the elevated band and easing, with Polymarket escalation contracts its top contributor. Those two readings diverge: current pressure is extreme while the forward signal is softening. Brent stands at $90.24, unchanged since the prior brief on 2026-07-31, with futures markets closed. gCaptain reports an oil spill spreading from a sanctioned shadow-fleet tanker off Oman.
