## Prediction

Over the next 24 hours, Tehran will double down rhetorically and operationally on its newly declared Strait of Hormuz shipping corridor, framing it as a safety and sovereignty issue while quietly coordinating deconfliction with Gulf states. Washington is likely to respond with warnings but avoid direct naval confrontation, seeking to preserve the fragile post-war containment framework. The result is a tense but managed stand-off that reassures some shippers while keeping a geopolitical risk premium alive in energy markets. Confirmation would be continued IRGC patrols and hailing of vessels without seizures, alongside measured US Navy statements; denial would be a sudden interdiction or boarding of a non-Iranian tanker triggering emergency UNSC or G7 consultations.

## Drivers

- Multiple alerts on Iran imposing mandatory Hormuz route and tankers turning back near Oman
- Emerging trend: Post-war US–Iran framework reshapes Gulf security and sanctions architecture
- Emerging trend: US–Iran diplomacy hardens into transactional containment-and-leverage
- Ships already rerouting near Oman after Iranian warning
