Bab el-Mandeb: The World's Most Dangerous Shipping Route?

The Bab el-Mandeb Strait is a 26-kilometer-wide passage between Yemen on the Arabian Peninsula and Djibouti and Eritrea on the Horn of Africa, connecting the Red Sea to the Gulf of Aden and the Indian Ocean. As of 2026, it is arguably the most dangerous shipping route in the world — a chokepoint where approximately 8.8 million barrels of oil and 12-15% of global trade by value transit daily under the active threat of missile, drone, and naval mine attacks from Houthi forces in Yemen. The strait's Arabic name translates to "Gate of Tears," a designation that has never been more appropriate.

Why Is Bab el-Mandeb Dangerous?

The danger at Bab el-Mandeb is not theoretical or historical — it is active, ongoing, and escalating. Since November 2023, Houthi forces have conducted the most sustained campaign of anti-shipping attacks since World War II.

Active Houthi Campaign

Between November 2023 and early 2026, Houthi forces launched over 150 attacks on commercial and military vessels in the Bab el-Mandeb approaches and the southern Red Sea. The arsenal deployed includes anti-ship ballistic missiles (ASBMs), anti-ship cruise missiles (ASCMs), one-way attack drones (OWA UAVs), unmanned surface vessels (USVs), and naval mines. The attacks have struck or damaged over 20 commercial vessels, sunk the bulk carrier MV Rubymar in February 2024, and killed crew members aboard the MV True Confidence in March 2024.

The Houthis' weapons capability has surprised military analysts. The group has demonstrated the ability to target vessels at ranges exceeding 200 kilometers from the Yemeni coast, effectively covering the entire Bab el-Mandeb strait and much of the southern Red Sea. The use of ASBMs — missiles that follow a ballistic trajectory before terminal guidance — represents a capability previously associated only with state-level military forces.

Geographic Constraints

The navigable channels through the Bab el-Mandeb are narrow. The island of Perim (Mayyun), controlled by Yemen, divides the strait into two channels — the eastern Bab Iskender (approximately 3 kilometers wide) and the western Dact-el-Mayun (approximately 25 kilometers wide). While the western channel is broader, its navigable depth is concentrated in established shipping lanes that bring vessels within weapons range of the Yemeni coast.

Vessels cannot transit the strait at high speed due to traffic density and navigational constraints. A loaded container vessel or tanker transiting at 14-16 knots is a predictable target for shore-based weapons operators who can calculate intercept solutions with simple equipment.

Inadequate Defense

Despite the deployment of a US-led naval coalition (Operation Prosperity Guardian) and European naval forces (EU NAVFOR Operation Aspides), the military response has been unable to eliminate the Houthi threat. Naval vessels have intercepted numerous incoming missiles and drones, but the volume of attacks exceeds defensive capacity. US and UK airstrikes on Houthi launch sites in Yemen have degraded but not destroyed the group's weapons infrastructure, which benefits from Iranian resupply and technical support.

Trade Routes Affected

Suez Canal Corridor

The Bab el-Mandeb is the southern gatekeeper of the Suez Canal corridor. Any vessel transiting the Suez Canal between Asia and Europe must also transit the Bab el-Mandeb. When the Bab el-Mandeb becomes unsafe, the Suez Canal effectively loses its southern access, forcing vessels to reroute via the Cape of Good Hope.

Oil and LNG Flows

Saudi Arabian oil exported via Red Sea terminals (Yanbu) and Qatari LNG transiting the canal to European markets must pass through the Bab el-Mandeb. The disruption has affected energy supply chains, with some LNG cargoes rerouting via the Cape and incurring additional transit time of 10+ days.

East African Trade

Ports in the Horn of Africa — Djibouti, Berbera, Aden, Mombasa — depend on the Bab el-Mandeb corridor for connection to global shipping networks. The security crisis has increased freight costs to East African ports by 200-300% from pre-crisis levels, as carriers pass through elevated insurance, fuel, and security costs.

Red Sea Ports

All ports on the Red Sea — Jeddah in Saudi Arabia, Port Sudan, Aqaba in Jordan, Eilat in Israel — are accessible only through the Bab el-Mandeb from the south or the Suez Canal from the north. The security crisis has disrupted transshipment operations at Jeddah and reduced cargo volumes at smaller Red Sea ports.

Rerouting and Economic Impact

Cape of Good Hope Diversions

Major container shipping lines — Maersk, MSC, CMA CGM, Hapag-Lloyd, and others — diverted significant vessel capacity to the Cape of Good Hope route. This rerouting adds approximately 3,500-6,000 nautical miles depending on origin-destination pairs, equivalent to 10-14 additional days of transit time. The additional distance consumes approximately 30-40% more fuel per voyage, costing $1-2 million per round trip for a large container vessel.

Freight Rate Impact

Container freight rates on the Asia-Europe route spiked following the initial diversions, with spot rates increasing from approximately $1,500/TEU in late 2023 to over $6,000/TEU in early 2024. While rates have moderated, they remain elevated above pre-crisis levels. The rate increase has been passed through to consumers in the form of higher prices for imported goods.

Insurance Costs

War risk insurance premiums for Red Sea transit have increased from a baseline of approximately 0.01% of hull and cargo value to 0.5-1.0%, adding $100,000-500,000 per transit for a laden ULCV. Some insurers have declined to provide coverage for Red Sea transits entirely, forcing shippers to accept the Cape route regardless of commercial preference.

Global Supply Chain Disruption

The rerouting has absorbed additional vessel capacity (longer voyages require more ships to maintain the same service frequency), contributing to container equipment imbalances, port congestion at Cape route waypoints, and schedule unreliability across global shipping networks. The disruption has been described by industry analysts as the most significant supply chain shock since the COVID-19 pandemic.

Security Operations

Operation Prosperity Guardian

The United States organized Operation Prosperity Guardian in December 2023 as a multinational naval coalition to protect commercial shipping in the Red Sea. The operation involves warships from the US, UK, France, and other allied nations conducting patrol, escort, and defensive operations. Coalition vessels have intercepted numerous Houthi missiles and drones, but the sheer volume of attacks has stretched defensive resources.

EU NAVFOR Operation Aspides

The European Union launched Operation Aspides in February 2024 as a defensive naval mission focused on protecting commercial shipping rather than offensive operations against Houthi targets. European warships have escorted commercial vessels and intercepted incoming threats in the Red Sea and Bab el-Mandeb approaches.

US/UK Strikes on Yemen

The United States and United Kingdom have conducted multiple rounds of airstrikes on Houthi weapons storage, launch sites, radar installations, and command facilities in Yemen. While these strikes have degraded Houthi capabilities temporarily, the group has demonstrated the ability to regenerate and resume attacks within days, supported by Iranian weapons resupply via maritime and overland routes.

Historical Context

The Bab el-Mandeb has been a contested waterway throughout maritime history. The strait has been significant since ancient Egyptian, Roman, and Ottoman naval operations in the Red Sea. During World War I, the Ottoman Empire attempted to mine the strait to prevent Allied access to the Red Sea. During the Yom Kippur War in 1973, Egypt imposed a naval blockade at the Bab el-Mandeb, blocking Israeli shipping access to the Red Sea.

The strait's modern security challenges intensified with Somali piracy (2008-2012), which created a threat zone extending from the Gulf of Aden across the Bab el-Mandeb approaches. International naval coalitions — including the Combined Maritime Forces (CMF) based in Bahrain — established counter-piracy patrols that partially addressed the piracy threat but proved insufficient against the qualitatively different Houthi campaign.

Conclusion

The Bab el-Mandeb's status as the world's most dangerous shipping route is not a transient condition — it reflects deep structural factors including Yemen's civil war, Iranian proxy strategy, the limits of naval defense against shore-based asymmetric threats, and the fundamental geographic vulnerability of the strait itself. Until a political resolution addresses the Houthi campaign — which is linked to the broader Yemen conflict and Iran-Saudi-US regional dynamics — the Bab el-Mandeb will remain a chokepoint where global trade meets armed conflict. For shipping lines, port operators, and cargo interests, the question is not whether to plan for Bab el-Mandeb disruption, but how to build supply chains resilient enough to function when the Gate of Tears is closed.
