Houthis Threaten Full Bab el-Mandeb Closure: What a Dual-Chokepoint Shutdown Would Mean for Global Shipping

The Threat

Houthi deputy information minister Mohammed Mansour has confirmed what maritime security analysts have feared for weeks: closing the Bab el-Mandeb strait is 'among our options — we are conducting this battle in stages.'

This is the first explicit acknowledgment by a senior Houthi official that the group is prepared to shut down the world's second-most-critical maritime chokepoint. Combined with Iran's ongoing Hormuz blockade, a dual closure would affect approximately 48% of all chokepoint-dependent global trade — an unprecedented scenario in modern maritime history.

The Evidence Is Building

The Houthi threat is not rhetorical. The operational evidence is accelerating:

• April 10: Triple attack — MSC Gina (targeted for the second time), MSC Darwin, and a US destroyer in the Gulf of Aden. This was the highest-tempo attack day of the current campaign.
• April 9: Maersk Yorktown, a US-flagged commercial vessel escorted by USS Mason and USS Laboon, was targeted by a missile that was intercepted. This marked the first time a US-flagged commercial ship was directly attacked.
• MSC Orion: Attacked 600 kilometers offshore — the furthest Houthi strike ever recorded, demonstrating expanded reach.
• Two commercial vessels sunk in April alone.
• Washington Institute assessment: Houthi attacks demonstrate 'strengthened control' over Red Sea transit.

The Dual-Chokepoint Math

If Bab el-Mandeb closes alongside Hormuz, the numbers are staggering:

Hormuz (currently blocked):

• 20% of global oil supply
• ~21 million barrels/day of oil flow
• 135 ships/day normally
• Currently: 0-3/day

Bab el-Mandeb (threatened):

• 12-15% of global trade
• ~6.2 million barrels/day of oil
• 70+ ships/day normally
• Currently: operating but under sustained attack

Combined impact: ~27 million barrels/day of oil flow disrupted. Saudi Arabia has already diverted 5 million barrels/day to its Red Sea terminal at Yanbu — which increased Bab el-Mandeb crude transit by 21% month-over-month in March. More traffic through BEM means more targets for Houthi missiles.

The Saudi diversion intended to bypass Hormuz has created a feedback loop: every barrel diverted to Yanbu increases BEM's strategic value as a Houthi target.

Why This Changes the Operator Calculus

Until now, the Cape of Good Hope route has been the default bypass for both chokepoints. But a dual closure changes the economics fundamentally:

• Cape route from Asia to Europe: adds 10-14 days vs Suez
• Cape route from Gulf to Asia: adds 15-20 days vs Hormuz
• Combined rerouting: every major East-West and Gulf-to-Asia trade lane affected simultaneously
• Vessel demand surge: longer routes = more vessels needed = freight rate explosion
• Bunker costs: additional fuel for extended voyages at already-elevated prices

The insurance implications compound the routing costs. War-risk premiums for BEM transit are already elevated, and explicit closure threats will push rates higher. The Suez Canal — which has seen 115 safe days — is at risk of traffic reversal if Houthi attacks resume at pre-ceasefire intensity.

The Iran Connection

Houthi actions are not independent. Multiple intelligence sources confirm:

• Iran is pushing the Houthis to prepare for a renewed Red Sea campaign contingent on US escalation.
• The Jerusalem Post reports Houthis are using BEM as a 'trump card' to prevent Gulf states from joining US military operations.
• Houthi ballistic missiles launched at Israel during the ceasefire demonstrate continued operational capability and willingness to escalate.

The dual-chokepoint threat is Iran's strategic insurance policy: even if Islamabad produces a Hormuz agreement, Tehran retains leverage through its Houthi proxy's control of BEM.

What Operators Should Do Now

1. Model the dual-closure scenario using our Route Risk Calculator — it accumulates risk scores across all chokepoints in your specific route.
2. Check your BEM exposure: if your vessels transit Red Sea lanes, the Houthi threat escalation means reviewing war-risk coverage NOW, not after an incident.
3. Evaluate Cape alternatives: for Asia-Europe and Gulf-Asia trades, calculate the breakeven point between BEM war-risk surcharges and Cape route fuel/time costs.
4. Monitor ASPIDES: the European Red Sea Task Force is deployed and ready, but escort capacity is limited. Know your flag state's participation status.
5. Watch the Islamabad outcome: if talks fail Saturday, Houthi activation probability increases significantly. The window for BEM route planning is NOW.
