## Prediction

Within seven days, Iran is likely to broaden its maritime operations beyond direct clashes with US forces to include harassment, boarding, or detention of third-country tankers perceived as violating its declared Hormuz closure or carrying Saudi, Emirati, or Iraqi crude. This asymmetric campaign will seek to impose costs on US-aligned exporters and to fracture the emerging coalition supporting the blockade. The risk of misidentification and escalation will rise sharply, particularly for Indian, European, and East Asian-flagged vessels. Confirmation would be IRGC Navy announcements of 'inspections' or detentions of foreign tankers and AIS evidence of diverted routes into Iranian waters; denial would involve Iran strictly limiting actions to US or clearly US-aligned shipping.

## Drivers

- Iran’s declaration of total Hormuz closure
- US disabling of multiple Iran-linked tankers near Oman, raising stakes
- Iran’s historical use of tanker seizures to pressure adversaries
- Emerging trend: Hormuz weaponized as information and economic battlespace
