## Prediction

In the next 24 hours, Iran’s IRGC Navy is likely to increase close shadowing, radio warnings, and limited harassment of US and allied warships or commercial vessels near Hormuz, but is unlikely to execute a high-casualty or ship-sinking strike. Tehran has reaffirmed legal claims over the strait and faces domestic pressure to respond, yet is simultaneously pursuing talks and demanding regional de-escalation. This creates incentives for symbolic but reversible shows of force such as fast-boat swarms, overflights, and temporary interference with flagged traffic. A miscalculation incident remains a non-trivial tail risk but is less probable than calibrated signaling.

## Drivers

- Iran public insistence on right to exercise sovereignty over the Strait of Hormuz
- US boarding and diversion of Iranian tankers amid talk of a blockade
- Tehran’s stated desire to avoid wider regional war while warning conflict could spread
