## Prediction

Within seven days, Iran is likely to operationalize elements of its announced Hormuz ‘restricted zone’ by boarding, diverting, or briefly detaining at least one commercial vessel it deems hostile-linked, probably under the pretext of smuggling or sanctions enforcement. Such an interdiction would be carefully calibrated to avoid killing foreign crew while demonstrating Tehran’s willingness to weaponize maritime traffic control. The move would provoke US and allied naval escorts, new advisories, and possibly limited countermeasures against IRGC naval assets, further entrenching a tit-for-tat maritime contest. Confirmation would be verifiable reporting of a seized or diverted tanker or product carrier; denial would be a week of unimpeded traffic despite continued rhetoric.

## Drivers

- Iran’s explicit threat to list transiting ships as targets in a new restricted zone
- Claims of recent missile test over a US warship and ongoing targeting of 'smuggled' petroleum
- Escalatory trend in US–Iran maritime and missile confrontation
- Domestic pressure from gasoline shortages incentivizing external diversion
