Bab el-Mandeb is the narrow strait between Yemen on the Arabian Peninsula and Djibouti and Eritrea in the Horn of Africa. It connects the Red Sea to the Gulf of Aden and the Arabian Sea.
Its importance comes from what lies north of it: the Suez Canal. Ships moving between Asia and Europe through Suez usually have to pass Bab el-Mandeb as well. If the strait becomes unsafe, many vessels divert around the Cape of Good Hope at the southern tip of Africa.
That detour can add thousands of kilometres and days to a voyage. More sailing time means more fuel, crew time, ship capacity and insurance cost. Because container ships, oil tankers and gas carriers all use these routes, the impact can spread to consumer goods, energy and industrial inputs.
Energy markets are especially sensitive. EIA data show that several million barrels per day of oil and petroleum products have moved through Bab el-Mandeb in recent years. The route is also connected to LNG trade and to Saudi and Gulf exports bound for Europe.
The Houthi conflict in Yemen has made the strait a recurring global concern. Missile and drone attacks on shipping can reduce traffic even when the waterway is not physically blocked, because shipping companies may decide the risk is unacceptable.
There are alternatives, but they are costly. Oil can sometimes move through pipelines to Red Sea or Mediterranean ports, while ships can sail around Africa. Neither option fully replaces the speed and capacity of the Suez-Bab el-Mandeb route.
This is why a local conflict in Yemen can become a global freight story within days. The strait is a geographic bottleneck connecting regional security to supermarket prices, factory supply chains and energy markets far away.
