## Prediction

Within 24 hours, Iranian IRGC naval units and drones are likely to step up close harassment of commercial and escort vessels around the Strait of Hormuz without yet attempting mass ship seizures. This will include aggressive maneuvering, illumination by fire-control radars, and potential disabling fire against isolated tankers to reinforce Tehran’s declared closure. Commercial ships, especially those flagged to US allies or insured in London, will face immediate route and timing decisions. Expanded harassment would lock in a de facto risk corridor that nudges US and Gulf navies closer to direct engagements. A sudden pause in incidents following quiet US–Omani mediation would would undercut this forecast.

## Drivers

- Multiple tanker strikes reported in Hormuz including a third hit
- Iran’s explicit declaration that Hormuz will stay closed until US ends naval blockade and war
- Oman halting US tanker escorts, increasing space for Iranian probing
- Emerging trend: Hormuz as contested economic battlespace and Iranian leverage over chokepoint
