## Prediction

Within 24 hours, IRGC Navy units are likely to increase close approaches, warnings, and short-duration shadowing of tankers near the Strait of Hormuz while avoiding actual disablement or seizure. Commercial ships, especially those with perceived US, UK, or Israeli links, will face heightened boarding or inspection threats, raising crew anxiety and insurance concerns. This keeps military pressure on Washington and regional states without triggering an immediate US kinetic response beyond current escorts. Confirmation would include AIS track slowdowns, reported hails/boarding attempts, or temporary course changes away from Iranian patrol craft; disconfirmation would be uninterrupted traffic with no harassment reports and Iranian radio traffic de‑emphasizing closure.

## Drivers

- IRGC repeated radio declarations that Hormuz is closed and ships face 'security risks'
- CENTCOM reporting of heavy traffic with US escorts already in place
- Pattern of prior Iranian use of harassment and limited seizures as coercive tools
