## Prediction

Within 24 hours, at least one major commercial vessel is likely to report close harassment, warning shots, or drone overflight by Houthi units near Bab el-Mandeb rather than a full sinking attempt. The Houthis will test their new leverage by visibly asserting control, inspecting or shadowing ships, and probing how far they can push before triggering direct Western retaliation. This will inject fear into crews and operators, leading some to self-reroute or slow-roll transits even without formal closures. Confirmation would be naval advisories or insurer alerts citing specific harassment events; denial would be a full day of unimpeded vessel reporting through AIS and naval channels despite Houthi gains.

## Drivers

- Houthis now claim de facto control over both shores and islands at Bab el-Mandeb
- Previous Houthi pattern of graded escalation from harassment to attack
- High visibility of current territorial breakthrough incentivizing symbolic shows of control
- Absence so far of a decisive coalition kinetic response
