Houthi Anti-Ship and Drone Activity Near Bab el-Mandeb Likely to Spike as Trenches Activated

Moderate confidence (65%)
Risk direction: escalatory · Impact: HIGH
Full prediction
In the coming 24 hours, Houthi forces are likely to pair their new Bab el‑Mandeb fortifications with limited anti-ship threat demonstrations and drone launches toward Saudi territory. Commercial shipping transiting the southern Red Sea and Saudi border communities will face elevated risk of harassment, near-miss events, or temporary route diversions. Even without a major strike, visible activity will harden insurers’ and navies’ perception of a militarized chokepoint, nudging up war-risk premia and naval presence demands. Confirmation would include attempted drone or missile launches toward shipping lanes or Saudi cities; a quiet period alongside reports of intensified behind-the-scenes pressure from Iran or China would moderate this forecast.
