## Prediction

Within seven days, Iran is likely to formalize or de facto implement a regime in which selected tankers and cargo vessels can transit Hormuz only after prior notification, possible escort, and compliance checks by IRGC forces. This will include publicized 'approved' transits to demonstrate control while maintaining the broader closure threat. The regime will selectively favor neutral or friendly states (e.g., China, some Asian buyers) and penalize those seen as hostile, embedding geopolitical leverage into shipping flows. Western navies will increase presence but avoid direct confrontation unless a major incident occurs.

## Drivers

- IRGC enforcement strike on non-coordinating tanker
- Wording in alerts that vessels must coordinate to transit
- Iranian history of using calibrated chokepoint control for bargaining
- Lack of immediate US appetite for full-scale confrontation amid alliance strain
