Houthis Seize Strategic Red Sea Island, Raising Global Trade Risks

Shibbir Ahmed, NEW YORK — Iran-aligned Houthi forces have seized the strategic Mayun Island at the southern entrance to the Red Sea, tightening their grip around the Bab el-Mandeb Strait and raising fresh concerns over global shipping and energy supplies.

The Houthis also took control of Yemen’s Red Sea port city of Mokha on Thursday and have advanced along the coast toward strategic islands, according to Reuters and the Associated Press. The developments represent the group’s most significant territorial gains since a 2022 truce largely halted Yemen’s civil war.

Mayun Island, also known as Perim, sits in the Bab el-Mandeb Strait, a critical maritime chokepoint connecting the Red Sea with the Gulf of Aden. About 12% of global goods normally pass through the waterway, making any prolonged disruption a potential threat to international trade.

The latest Houthi advance comes as shipping through the nearby Strait of Hormuz has already been severely disrupted by the wider Middle East conflict. Saudi Arabia has increasingly relied on the Red Sea route to move oil after traffic through Hormuz became heavily restricted.

The potential loss of secure access to both major maritime corridors has heightened concerns among energy traders and shipping companies. Reuters reported that Saudi crude production fell to about 6 million barrels per day in August, its lowest level in more than three decades, partly because of disruptions linked to attacks on shipping around the Bab el-Mandeb.

Oil markets have responded sharply to the growing risks. Brent crude rose above $100 a barrel this week, while U.S. West Texas Intermediate crude also crossed the $100 threshold as traders assessed the possibility of further supply disruptions.

Saudi Arabia has responded to the Houthi advance with military action. A Houthi-controlled broadcaster reported that Saudi forces carried out airstrikes on the airport in Mokha after the port city fell to the group. There were no immediate reports of casualties or significant damage.

The escalation has also raised fears of a renewed wider conflict inside Yemen. More than 46,000 people have fled their homes since the latest fighting began, according to the U.N. migration agency, while Yemen’s internationally recognized government has indicated that it intends to launch a counteroffensive to recover territory captured by the Houthis.

For international shipping, the main concern is whether the Houthis will use their new positions to further restrict commercial traffic through the Bab el-Mandeb. Shipping through the waterway had already fallen substantially after Houthi attacks on commercial vessels beginning in late 2023, prompting many shipping companies to reroute vessels around Africa.

With both the Bab el-Mandeb and Strait of Hormuz facing serious security challenges, businesses are preparing for potentially higher transportation and energy costs. Any prolonged disruption could affect oil prices, shipping rates and the movement of goods between Asia, the Middle East and Europe.

The latest developments have therefore transformed the Houthi advance from a regional military development into a growing concern for global trade and energy markets.
