**Heightened Houthi territorial gains around Mocha and Perim Island, combined with targeted attacks on Saudi-linked vessels and infrastructure since July, have driven the sharp contraction in Bab el-Mandeb transits.** Recent IMF PortWatch data show a 7-day average of roughly 26 vessels per day through mid-October—well below the 33-day pre-disruption baseline—with weekly totals clustering near 180–200. Saudi crude flows have been redirected via the Sumed pipeline and Suez, while broader commercial traffic faces elevated war-risk premiums and selective avoidance. This positions the 170–189 outcome as the market-implied consensus, reflecting persistent security constraints and partial rerouting rather than outright closure. Upcoming catalysts include any escalation in Red Sea incidents or shifts in carrier routing decisions that could alter the weekly count.
