## Prediction

Over the next 24 hours, IRGC naval and small boat units are likely to sustain de facto traffic management in the Iran-side Strait of Hormuz corridor, using radio threats and close passes to keep commercial shipping out of the Oman-side route. Commercial ships, Gulf navies, and Western militaries will be forced to accept higher collision and harassment risk while avoiding kinetic confrontation during the sensitive period around Khamenei’s funeral and nuclear talks. This will harden a new operational status quo where Iran proves it can reshape flows without formally closing the strait, raising pressure on US and GCC planners to respond without triggering war. Confirmation would include persistent AIS patterns favoring the Iran lane, additional radio threat recordings, and visible IRGC patrol clustering; refutation would be a rapid, sustained return of traffic to the Oman-side channel, likely after visible US/GCC naval shadowing.

## Drivers

- Multiple reports that IRGC radio threats have emptied the Oman-side passage in hours
- CENTCOM theater assessment citing tightened Iranian control during a formal pause in direct hostilities
- Emerging trend: Iran weaponizes Hormuz control and funerary spectacle as strategic leverage
- Iran blaming US-Israel for Khamenei assassination and promising revenge, raising signaling value of non-kinetic leverage
