## Prediction

Over the next seven days, Western and key Asian importers, along with Gulf partners, will likely raise formal concerns with Oman and Iran over the proposed Strait of Hormuz 'environmental protection fee,' seeking clarity and limitations. Muscat will try to frame the scheme as regulatory and modest to preserve its mediating role, slowing implementation details. Washington and European capitals are unlikely to impose new sanctions solely over the fee in this window but will signal that using it coercively could trigger countermeasures. The result will be heightened diplomatic friction and legal scrutiny, not yet a crisis.

## Drivers

- Iran’s announcement of shipping fee via joint Iran–Oman system
- CENTCOM theater threat rated ELEVATED with maritime leverage concerns
- Global dependence on Hormuz transit for oil and LNG
