Houthi Red Sea Embargo Threatens Saudi Oil Exports

Houthi rebels in Yemen announced Monday they will impose a maritime embargo on Saudi Arabia, targeting vessels in the Bab el-Mandeb Strait. Saudi Arabia's foreign ministry condemned the move and said it would take all necessary measures to protect its ships, according to a statement.

The Bab el-Mandeb Strait, connecting the Red Sea to the Gulf of Aden, carries about 10-12% of global maritime trade each year. The Red Sea route has become more critical for Saudi Arabia after disruptions in the Strait of Hormuz, which normally handles about a fifth of the world's oil and gas. Saudi Arabia has diverted exports to the Red Sea, and the port of Yanbu now handles more than 70% of the country's crude oil shipments.

The Houthi threat adds risk to a route that already faced heightened insurance costs. Premiums for ships transiting the Red Sea have risen since the announcement, shipping industry reports said. Higher insurance costs are typically passed on to end consumers, adding to inflationary pressures.

If the blockade expands to other countries, vessels would need to take the longer route around South Africa's Cape of Good Hope, adding days and millions of dollars per voyage. For now, the Houthis have only declared a blockade on Saudi ships, not a closure of the corridor to all traffic.

Saudi Arabia's east-west pipeline, connecting Abqaiq to Yanbu, was restored to full capacity earlier this year, providing an alternative to Hormuz. For more on crude oil infrastructure, see the crude oil profile.

The situation remains fluid. Shipping analysts said the risk premium on Red Sea passages is likely to persist as long as the Houthis maintain the threat.
