Houthi-Controlled Bab el-Mandeb Begins Selective Denial of Saudi-Flagged Shipping

Risk direction: escalatory · Impact: CRITICAL
Full prediction
Within 24 hours, Houthi and allied Iran-backed units are likely to enforce de facto denial of passage for Saudi-flagged or Saudi-chartered tankers and product carriers through Bab el-Mandeb, while allowing some non-Saudi and non-U.S.-linked traffic. This will create an immediate split-risk environment in the southern Red Sea, forcing Saudi and some Western vessels to pause, reroute, or sail with higher escort requirements. Strategically, the move transforms the corridor into a contested battlespace rather than a universally accessible trade route, pressuring Riyadh and Washington to choose between military rollback and tacit acceptance of a new status quo. Confirmation would come from AIS tracking showing Saudi-affiliated ships turning away or loitering south of Bab el-Mandeb and public or leaked instructions from insurers recommending avoidance; denial would be a visible, unimpeded Saudi tanker transit through the chokepoint.
