Iran-backed Houthis seize ports and islands, threatening Red Sea energy lifeline

Iran's influence in the Middle East has once again come to the fore. Through its backed Yemeni Houthi rebels, it successfully captured the strategic Red Sea port of Mocha and Perim Island, which controls the Bab el-Mandeb Strait, in a series of operations this week. The port of Mocha is a vital maritime gateway in northern Yemen, historically serving as a distribution hub for humanitarian aid and commercial cargo, while Perim Island sits at the entrance of the Bab el-Mandeb Strait connecting the Red Sea to the Gulf of Aden, making it one of the world's key chokepoints for oil and natural gas transportation. The simultaneous control of both locations effectively enables Iran and its proxies to form a "giant pincer" at the northern and southern ends of the Arabian Peninsula, exerting a direct impact on the international energy supply chain.

The Bab el-Mandeb Strait handles approximately three million barrels of crude oil daily, accounting for more than 10 percent of the world's total seaborne crude oil volume. Since 2021, the strait has repeatedly faced security alerts due to the Yemeni civil war. However, the direct control of Perim Island by Iranian-backed armed forces means they may in the future subject passing vessels to inspections, levy transit fees, or even use force to block them. If tensions persist, shipping companies will be forced to reroute via the Suez Canal or around the Cape of Good Hope, significantly increasing voyage times and costs, and further driving up international oil prices.

The root of Yemen's civil war can be traced back to 2014. The standoff between the Houthi rebels and the government forces supported by the Arab coalition has plunged the country's infrastructure and economy into a prolonged collapse. Iran has long supported the Houthi forces through political and military backing, thereby expanding its strategic depth between the Persian Gulf and the Red Sea. This capture of Mocha port not only enhances the resupply capabilities of the Houthi forces but also allows Iran to establish a more direct logistics and intelligence network along the Red Sea coast, further strengthening its control over international shipping lanes.

The international community's response to this development has been quite cautious. The United States and the European Union have repeatedly called on Iran to halt its military assistance to the Houthi rebels, warning that relevant sanction mechanisms will be activated if the security of Red Sea shipping lanes is threatened. Meanwhile, maritime security organizations have dispatched additional escort fleets to patrol near the Bab el-Mandeb Strait to protect commercial vessels from sudden attacks. Nevertheless, if Iran and its proxies continue to restrict shipping lane access using a "pincer" approach, fluctuations in the global energy market will be inevitable, with impacts being particularly pronounced for Asian and European countries reliant on Middle Eastern crude oil.

From a long-term perspective, by controlling key nodes in the Red Sea and the Bab el-Mandeb Strait, Iran is attempting to gain greater bargaining leverage in energy diplomacy. If the situation fails to ease, it may prompt oil-importing countries to accelerate the diversification of their energy sources and increase investments in alternative energy and liquefied natural gas. This move will not only alter the global energy supply and demand landscape but may also intensify geopolitical competition and uncertainty. When formulating energy policies, nations must simultaneously consider maritime security, supply chain resilience, and diplomatic engagement with Iran.

In summary, Iran's dual occupation of the Red Sea and the Bab el-Mandeb Strait through the Yemeni rebels has posed a substantive threat to global crude oil transportation. This move not only exacerbates tensions in the Middle East but also impacts the international energy market, forcing various countries to re-evaluate their strategies for energy security and shipping lane protection. In the absence of effective diplomatic and security interventions in the future, these risks will continue to fester, posing a long-term challenge to global economic recovery and energy stability.
