Situation

The Strait of Hormuz remains the center of a contested operational and legal standoff. Iranian state media and the IRGC have declared the strait closed until further notice, and Iranian state media IRNA reports that a second vessel violating regulations was struck during a retaliatory military operation. Separately, IRNA claims the IRGC struck logistic support centers and fueling platforms at Oman's Port of Duqm serving US aircraft carriers. UKMTO and NAVCENT counter that the southern Omani-coast transit route remains open and has been expanded to two-way traffic per a 12 July JMIC advisory; neither agency accepts Iran's closure declaration as physically enforced. Iran and Oman have agreed to continue consultations on navigation security, per IRNA, adding a diplomatic thread to an otherwise kinetic picture. A container ship caught fire off Oman and India condemned the attack on the GFS Galaxy vessel, per unconfirmed scraper-sourced reports. The Brent quote stands at $76.01, unchanged since the 2026-07-11 brief; no new market print has been produced. The Crisis Pressure composite is 86 (extreme), with event pressure as the top driver. The 30-day Escalation Forecast reads 61 (high), led by Polymarket closure odds; the gap between present state and forward expectation reflects uncertainty about whether current intensity is sustainable or approaching a resolution inflection. PortWatch recorded 34 transits on 2026-07-05, against an 88-per-day pre-crisis baseline; scraper-derived 24-hour arrivals at Gulf ports show 560 vessels, with 438 anchored or stopped.
