The Strait of Bab el-Mandab is a chokepoint between the horn of Africa and the Middle East, and a strategic link between the Mediterranean Sea and Indian Ocean. It is located between Yemen, Djibouti, and Eritrea, and connects the Red Sea with the Gulf of Aden and the Arabian Sea. Exports from the Persian Gulf must pass through Bab el-Mandab before entering the Suez Canal. In 2006, an estimated 3.3 million bbl/d flowed through this waterway toward Europe, the United States, and Asia. The majority of traffic, around 2.1 million bbl/d, flows northbound through the Bab el-Mandab to the Suez/Sumed complex.

Bab el-Mandab is 18 miles wide at its narrowest point, making tanker traffic difficult and limited to two 2-mile-wide channels for inbound and outbound shipments. Closure of the Strait could keep tankers from the Persian Gulf from reaching the Suez Canal or Sumed Pipeline, diverting them around the southern tip of Africa. This would effectively engage spare tanker capacity, and add to transit time and cost.

The Strait of Bab el-Mandab could be bypassed through the East-West oil pipeline, which crosses Saudi Arabia with a 4.8 million bbl/d capacity. However, southbound oil traffic would still be blocked. In addition, closure of the Bab el-Mandab would block non-oil shipping from using the Suez Canal, except for limited trade within the Red Sea region.

Security remains a concern of foreign firms doing business in the region, after a French tanker was attacked off the coast of Yemen by terrorists in October 2002.
