The Red Sea Blockade and Global Energy Supplies - Its Closure by the Houthis, a

Yemen's Iran-aligned Houthis will impose a naval blockade on Saudi Arabia, further disrupting the global energy market, which is already severely constrained by Iran's closure of the Strait of Hormuz.

Yemen sits on the Bab el-Mandeb Strait – the southern gateway to the Red Sea – and closing it would open a new front in the energy crisis and Iran’s all-out conflict with the US. With the disruption of Hormuz, the Red Sea has become a critical alternative point for Gulf oil and other products. A serious disruption would mean both major oil export routes to the Middle East would be closed simultaneously.

Iran's partial blockade of the Strait of Hormuz, after Israel and the US attacked it on February 28, cut off most oil and other exports from the Gulf, driving up prices and causing a global energy shock.

Saudi Arabia responded by diverting more than 70% of its normal daily crude oil exports to the Red Sea port of Yanbu. Ships from Yanbu bound for Europe go north through the Suez Canal. Those bound for Asia go south through the Bab el-Mandeb.

Shipments from Yanbu averaged 4 million barrels per day in recent weeks according to data from Kpler and Signal Ocean, up from about 973,000 barrels per day a year ago.

Total oil volumes transiting through the Bab el-Mandeb Strait reached 7.4 million barrels per day in June, or about 7% of global oil production, according to Kpler data, up from 4.2 million barrels per day last year.

This has provided a lifeline to the energy market, helping to keep global oil prices low. Saudi Arabia is considering an expansion of its crude oil pipeline on the Red Sea coast, Reuters reported last week.

Following Hamas's attack on Israel on October 7, 2023, and Israel's campaign in Gaza, the Houthis began shelling Israel and ships in the Red Sea, saying they were doing so in support of the Palestinians. The attacks severely disrupted global shipping, prompting other major companies to divert around Africa — a much longer and more expensive route.

Traffic in the Red Sea has not recovered since then, with traffic through the Suez Canal falling by 52% in 2025 compared to 2023 levels and at its lowest level in at least 50 years, Suez Canal Authority data show.
