Bab-el-Mandeb
Overview
The Bab-el-Mandeb Strait (Arabic for 'Gate of Tears') is a strait connecting the Red Sea and the Gulf of Aden, located between southwestern Yemen to the east and Djibouti and Eritrea in Africa to the west. Together with the Suez Canal, it serves as the final gateway for maritime logistics linking Europe and Asia, and because it is narrow and carries heavy traffic, it is regarded as one of the world's most sensitive geopolitical chokepoints (bottlenecks). Since late 2023, attacks on commercial vessels by Yemen's Houthi rebels have made it a key variable in international logistics and energy security.

Geographical Characteristics
The strait's total width is only about 26–32 km, and it is divided by the central Perim Island into the eastern 'Iskander (Alexandria) Strait' and the western 'Danzkur Strait.' The main route actually used by large vessels is so narrow that it is only around 3 km wide. Depth is generally 100–300 m, and to the north it leads to the Red Sea, while to the south it connects through the Gulf of Aden to the Arabian Sea and the Indian Ocean. Both shores have desert climates and weak land transport infrastructure, making reliance on the sea passage absolute.
Historical Background
Since ancient times it was a key point on spice, coffee, and ivory trade routes, and the name 'Gate of Tears' is most likely derived from the tears of sailors shipwrecked during voyages. With the opening of the Suez Canal in 1869, it became an essential transit point on the Europe–Asia route, and during the 1967–1975 closure of the Suez Canal, its value as a gateway to detour routes became even more prominent. From the 1990s onward, with the spread of Somali piracy, it became a theater for international naval escort operations.
Strategic Importance
Bab-el-Mandeb is an area with a dense concentration of the US Fifth Fleet, China's PLA overseas support base in Djibouti, and military bases of France, Japan, Italy, and others. In China's Belt and Road (Maritime Silk Road) initiative, it is also classified as a key node linking the Indian Ocean and the Mediterranean. The United States has defined Bab-el-Mandeb as one of the six major maritime chokepoints on which the global economy depends and has regularly conducted freedom of navigation operations.
Economic Significance
About 10–12% of global maritime trade and more than 6 million barrels per day of crude oil and petroleum products pass through this strait. As the shortest route connecting Europe and Asia, it saves about 9,000 km in sailing distance and 10–14 days in transit time compared with going around the Cape of Good Hope. Most of Egypt's Suez Canal toll revenue is directly tied to transit volume through this strait, and it is a key variable determining the stability of European energy markets and Asian manufacturing supply chains.
Recent Developments
After Yemen's Houthi rebels began attacks in the Red Sea in November 2023 targeting Israel-linked vessels, the transit environment at Bab-el-Mandeb deteriorated sharply. The United States established Operation Prosperity Guardian and, together with the United Kingdom, carried out airstrikes on Houthi positions, but sporadic attacks continued throughout 2024.
In 2024, as many container shipping companies switched to the Cape of Good Hope detour, Suez Canal transit volume plunged by more than 50% year-on-year, and Egypt's canal revenue fell by billions of dollars. Freight rates on Asia–Europe routes soared by as much as 3–4 times, and war-risk insurance premiums also surged, leading some small carriers to abandon operations.
In 2025 as well, the Houthi rebels repeatedly paused and resumed attacks, using them as a bargaining chip, and the United States resumed large-scale airstrikes. In May of that year, a ceasefire agreement between the United States and the Houthis was announced, creating a temporary easing of tensions, but commercial vessels' full return to the route is proceeding cautiously. The international community is discussing the institutionalization of a multinational naval coalition to guarantee strait security, the establishment of a satellite- and drone-based early warning system, and a political resolution of the Yemeni civil war as parallel tasks. In the medium to long term, Saudi and UAE investment in Red Sea coastal logistics infrastructure and the India-Middle East-Europe Economic Corridor (IMEC) initiative are expected to further raise the strait's strategic value.
