## Prediction

In the next 24 hours, the US is likely to deepen operational enforcement of its de facto maritime ‘blockade’ near Iran—expanding boarding/diversion patterns and publicizing ‘safety’ rationales—while issuing coordinated statements with partners on Red Sea freedom of navigation. This will reassure European and Asian importers but will be read in Tehran as coercive, reinforcing Iran’s incentive to lean on Houthi control of Bab el‑Mandeb. The move increases friction risk with IRGC Navy or proxy vessels and could provoke symbolic Iranian harassment or cyber responses. Confirmation would be new reports of US-led diversions or inspections and NAVWARN-style advisories; a sudden softening of enforcement posture would undermine this forecast.

## Drivers

- Reports of a US ‘blockade’-style operation diverting 99 commercial vessels near Iran
- Twin chokepoint squeeze with Hormuz pressure and Houthi control of Bab el‑Mandeb
- US trend toward economic militarization to absorb Iran war energy shocks
- Need to signal commitment to allies’ shipping routes as risk premiums spike
