## Prediction

Over the coming week, Iran or Iran-aligned proxies will likely attempt additional harassment or close shadowing of US- or ally-linked commercial vessels in the Hormuz and northern Gulf area, using drones, fast boats, or electronic interference. These actions will be calibrated to signal capability and impose psychological and insurance costs without triggering direct large-scale US retaliation. Several such incidents may be resolved without kinetic engagement but will add to the perception of insecurity. A small number could involve shots fired or further drone shootdowns.

## Drivers

- Recent report of Iranian drones targeting a US tanker near Hormuz with its transponder off
- Iranian pattern of using harassment of shipping as leverage in disputes
- US sanctions on Iran’s Strait transit authority constraining Iran’s formal leverage channels
- Emerging trend framing a durable low-intensity US–Iran conflict in Hormuz
