## Prediction

Over the next 24 hours, Houthi forces are likely to enforce a de facto blockade on Saudi-flagged or Saudi-linked tankers transiting near Yemen, using additional anti-ship missiles and drones to deter new sailings and force diversions. Saudi and allied naval forces will increase escorts and air patrols, but risk-averse shipping companies will delay or reroute many cargoes rather than test Houthi strike capabilities. This will create a temporary operational choke on Saudi exports via the Red Sea, amplify pressure on alternative routes through the Gulf, and feed into Iranian narratives that maritime lanes are unsafe during US–Iran confrontation. Confirmation would include more tankers turning back, AIS-silent diversions, and fresh UKMTO warnings; contrarian evidence would be several Saudi tankers transiting unmolested under heavy escort.

## Drivers

- Multiple confirmed Houthi missile strikes on Saudi or Saudi-linked tankers near Al Shuqaiq
- Houthi public claims of a self-declared naval blockade forcing over ten tankers to turn back
- Limited Saudi naval ability to fully sanitize wide Red Sea waters in real time
- Ongoing US–Iran escalation incentivizing Iran-linked proxies to pressure Saudi energy exports
