## Prediction

Over the next seven days, the U.S.–Iran confrontation is likely to evolve into a sustained low-grade naval conflict, featuring intermittent attacks, boardings, or harassment not only of Iranian-linked vessels but also of third-country tankers perceived as violating the blockade or supporting rivals. Iran will increase use of proxies, drones, and fast boats to complicate attribution and raise costs for U.S. enforcement. The risk of a high-casualty incident involving a commercial crew or misidentified vessel will rise materially.

## Drivers

- Documented US enforcement of a blockade via direct fire on Iranian tankers
- Iran’s seizure of OCEAN KOI and retaliatory attacks on US ships
- Emerging trend: managed US–Iran limited war under a politically preserved ‘ceasefire’ fiction
- Complete freeze of mainstream tanker traffic through Hormuz
