The Bab al-Mandab is a geographical concept, specifically a narrow strait, or a maritime chokepoint, connecting the Red Sea to the Gulf of Aden and the Arabian Sea. Its name, meaning "Gate of Tears" or "Gate of Grief" in Arabic, refers to the historical dangers of navigating the waterway. The strait is located between Yemen on the Arabian Peninsula and Djibouti and Eritrea in the Horn of Africa. At its narrowest point, the strait is approximately 20 miles (32 kilometers) wide and is divided into two channels by Perim (Mayyun) Island.
The strait's strategic importance dramatically increased with the opening of the Suez Canal in 1869, which transformed it into a critical gateway for maritime trade between Europe and Asia, bypassing the long route around Africa. It functions as the southern access point to the Suez Canal route.
The mechanism of its importance lies in its role as a vital artery for global commerce; approximately 10-12% of global maritime trade and a significant volume of oil, estimated at 8.8 million barrels per day in 2018, passes through this corridor. It is considered the third busiest chokepoint for oil shipping globally.
The Bab al-Mandab is intrinsically connected to the Suez Canal and the Strait of Hormuz, as disruptions in any of these chokepoints can force vessels to take the costly and time-consuming detour around the Cape of Good Hope.
Recently, the strait has seen heightened geopolitical tension, with the Houthi militia in Yemen threatening a naval blockade and conducting attacks on commercial shipping in the Red Sea and the strait, which has caused some vessels to reroute. This has made maritime security a major concern, with the strait becoming a flashpoint in regional conflicts.
