## Prediction

Over the next 24 hours, Iran is unlikely to physically close or directly obstruct the Strait of Hormuz but will maintain a visibly elevated naval and Revolutionary Guard maritime presence. Tehran’s hardened rhetoric and creation of a ‘Persian Gulf Strait Authority’ point to coercive signaling rather than immediate war, while U.S. and allied navies will continue high-intensity interdiction and surveillance. Close approaches, radio warnings, and boarding operations may increase, raising the risk of an incident but still short of deliberate blockade. Any miscalculation could flip this assessment quickly, but political cost of open closure remains high for Iran.

## Drivers

- Iranian statements that the ‘era of trusting US diplomacy is over’ and readiness ‘for every scenario’
- Recent Iranian assertion of new control mechanism over Hormuz transit
- Reports of recent U.S. Navy interdiction of an Iranian tanker
- Emerging trend that Iran–US crisis is moving to structured coercive bargaining rather than open war
