## Prediction

Within 24 hours, IRGC Navy and affiliated militia boats are likely to increase close intercepts and inspections of commercial vessels at the approaches to the formally closed Strait of Hormuz to enforce the new Iranian insurance regime. Crews will experience more aggressive hailing, course demands, and boarding attempts, especially on tankers and LNG carriers perceived as non‑compliant. This will heighten miscalculation risk with US, UK, and GCC naval escorts and could generate an incident involving warning shots or temporary detention. Confirmation would be AIS track clustering and mariner reports of delays and boardings near Hormuz; denial would be a visible lull in IRGC small‑boat activity despite the insurance announcement.

## Drivers

- Iran mandate for new insurance regime on all ships transiting Hormuz
- Iran reiteration that Hormuz will not reopen without Lebanon ceasefire
- US President threat to "take over" the Strait of Hormuz
- Pattern of IRGC enforcement via small‑boat harassment in past crises
