Bab el-Mandeb Strait effectively closed by 2026?

Platform comparison

Market context

Traffic through the Bab el-Mandeb Strait has already faced severe disruption in 2026, with major carriers like Maersk pausing sailings amid escalating Middle East conflict and renewed Houthi missile operations against commercial vessels[4][9]. While the strait has not been formally closed, daily crossings have dropped sharply as shippers reroute for safety, mirroring the effective collapse seen in the Strait of Hormuz where traffic fell to just two outbound vessels daily after March 2026[3][7]. Despite this volatility, current market sentiment assigns near-zero probability to a full closure defined by a 7-day moving average of arrivals falling below 10, suggesting traders view seasonal slowdowns and security risks as insufficient to trigger the settlement threshold[1][2].

Key catalysts for traders include any announcement from Iran or Houthi leadership regarding coordinated military action, particularly the previously hinted “Hour Zero” joint operations with Iran that could escalate attacks on tankers[3]. Traders should monitor IMF PortWatch’s weekly transit data releases and watch for insurance withdrawal or GPS interference spikes similar to those affecting over 1,650 vessels in the Gulf of Oman during March 2026[8]. The settlement hinges on whether these security pressures combine with seasonal factors to push the 7-day average below 10 before June 2026, a scenario that remains unlikely given that even during peak crisis periods, Bab el-Mandeb traffic remained elevated relative to Hormuz[8].
