Will Bab el-Mandeb shipping transits recover to at least 80 percent of their pre-2024 baseline before the end of Q4 2026?
What moved
Iran reportedly asked the Houthis to prepare to shut Bab el-Mandeb if the US attacks Iranian infrastructure; a conditional threat to one of the world's most critical oil and shipping chokepoints.
The market transmission
The threat is contingent and not yet executed, but Bab el-Mandeb carries roughly 12% of global seaborne oil and a far larger share of container traffic between Asia and Europe. If enforced, closure would force tankers around the Cape of Good Hope, adding 10, 14 days to voyage time and lifting shipping costs sharply. Brent and WTI would reprice on supply route lengthening and insurance cost escalation. The probability hinges on whether a US strike on Iranian infrastructure occurs; absent that trigger, the threat remains posturing. Markets are pricing the risk of escalation, not the certainty of closure.
What would change this
Iran has incentivized Houthi action before; past threats to Bab el-Mandeb have not led to sustained closure. The conditional nature of this threat (triggered only by a US strike) means the immediate market impact depends on US escalation probability, not Houthi capability. Enforcement is distinct from preparation; the Houthis may be preparing without intending to execute or may lack the sustained capability to hold closure. If closure were to occur, it would disrupt southbound container traffic far more acutely than oil, given the Cape reroute is viable for crude but not containerized cargo on this timeline.
