## Prediction

Over the next 24 hours, Washington is likely to clarify at least part of the 'sweeping secondary sanctions' warned by Secretary of State Rubio, targeting entities that facilitate shipping to or from sanctioned Iranian ports. The rollout will probably emphasize enforcement against insurers, shipping companies, and intermediaries using non-compliant routes or Iranian transit permits that undercut the blockade. The aim will be to deter gray-zone shipping and align European and Asian partners behind the convoy regime. Full operational details will take longer to implement, but initial guidance or designations are probable. Contrarian outcome: the US delays formal announcements to avoid alienating key energy importers, opting for quiet diplomacy instead.

## Drivers

- Public US declaration of an 'effective blockade' on Iranian ports
- Rubio’s statement about sweeping secondary sanctions
- Need to backstop military posture with economic enforcement
- Pattern of US sanctioning behavior in past Iran crises
