Bab el-Mandeb Strait

The Bab el-Mandeb Strait is a narrow sea passage connecting the Red Sea with the Gulf of Aden, between Yemen and the African coast near Djibouti and Eritrea. It is a strategic maritime chokepoint because ships using the Suez Canal route between the Mediterranean Sea and the Indian Ocean must pass through it.

Position in the global shipping network

Bab el-Mandeb forms the southern gateway to the Red Sea, while the Suez Canal provides its northern connection to the Mediterranean. Together, these passages support a shorter maritime route between Europe and Asia than sailing around Africa.

• The strait links shipping lanes in the Mediterranean and Red Sea with the Gulf of Aden and, beyond it, the Arabian Sea and Indian Ocean.
• Its importance arises from the concentration of shipping through a narrow passage, where disruption can affect trade far beyond the surrounding countries.

Trade, energy flows and the costs of disruption

The strait carries containerised cargo as well as tankers transporting crude oil and petroleum products. Its security therefore matters both for the movement of manufactured goods and for international energy trade.

• It provides an important route for oil and petroleum products moving between the Persian Gulf, European markets and other destinations through the Suez Canal.
• Attacks on vessels, piracy or armed conflict can make transit unsafe even without a formal closure of the strait.
• Ships avoiding the Red Sea route may sail around the Cape of Good Hope, increasing voyage distance, journey time and fuel consumption.
• Disruption can raise freight charges and insurance costs, delay deliveries and disturb supply chains; longer voyages can also reduce the shipping capacity available for other cargo.
• The alternative route means disruption does not necessarily stop trade, but it can make trade substantially slower and more expensive.

Significance for India and maritime security

For India, Bab el-Mandeb matters particularly because the Red Sea-Suez route connects Indian ports with European markets. Protecting commercial navigation is consequently both an economic and a security concern.

• Disruption can affect Indian exports and imports through higher transport costs, delayed deliveries and risks to vessels and seafarers.
• Its energy significance should not be confused with the Strait of Hormuz: direct Persian Gulf-to-India shipping generally does not need to pass through Bab el-Mandeb.
• Dependence on this chokepoint highlights the importance of maritime security, cooperation against threats to merchant shipping and contingency planning for alternative routes.
