## Prediction

Over the next 24 hours, Iran’s naval and IRGC units will likely step up harassment, inspections, or limited seizures of small vessels and possibly shadow larger tankers transiting near the Strait of Hormuz, short of large-scale kinetic engagement. This will test U.S. and allied red lines while aligning with Tehran’s public vow to keep Hormuz shut until sanctions are lifted. Increased close encounters heighten miscalculation risk and could quickly escalate into warning shots or limited damage incidents, jolting global shipping sentiment. Confirmation would include AIS gaps near Hormuz, additional reported boardings like the Sirik diesel seizure, or U.S. Navy statements about unsafe interactions; a visible decrease in Iranian patrol activity or backchannel de-escalation leaks would weaken this forecast.

## Drivers

- Iranian parliament speaker’s explicit declaration tying Hormuz closure to U.S. sanctions relief
- Recent Iranian seizure of boats with diesel off Sirik near Hormuz
- U.S. insistence there are no talks with Iran and continuation of naval blockade posture
