War in the Middle East Houthi blockade: What would that mean for world trade?

The Houthi militia has imposed a naval blockade in the Bab al-Mandab Strait, a critical waterway connecting the Red Sea to the Gulf of Aden and the Suez Canal. This move threatens global trade routes, particularly those transporting oil and other goods through the region. The strait, which lies between Yemen and the Arabian Peninsula, is one of the busiest maritime corridors in the world. According to reports, the Houthi forces have reportedly forced six ships to turn back, though independent confirmation of this claim remains elusive. The Houthi movement emerged in the 1990s in northern Yemen as a military, political, and religious group opposing the government in Sanaa. Over the past decade, they have been engaged in a civil war against the internationally recognized government backed by Saudi Arabia. The conflict has spilled over into neighboring Gulf states, with the Houthis launching missile and drone attacks. Iran supports the Houthis as part of its regional “axis of resistance,” which includes groups such as Hezbollah in Lebanon, Shia militias in Iraq, and Hamas in Palestine. However, the Houthis do not fully recognize Iran’s supreme leader as their highest religious authority, distinguishing them from other groups within the axis. Their primary motivations remain internal, focused on consolidating power within Yemen rather than aligning directly with Iranian strategic goals. The current blockade follows a breakdown in a ceasefire agreement signed in 2022 between the warring parties. The truce held until last week, when the internationally recognized Yemeni government attacked the Sanaa airport to prevent the landing of an Iranian aircraft. The Houthis blamed Saudi Arabia for the incident and retaliated by firing rockets at the Abha airport in southern Saudi Arabia. They then declared a naval blockade targeting Saudi vessels. Austrian Middle East expert Gudrun Harrer noted that while the conflict is primarily internal, its effects extend beyond Yemen, influencing regional stability. The Houthis control much of northern Yemen and large portions of the western coast along the Red Sea. By imposing the blockade, they aim to assert dominance over these areas and reduce reliance on Saudi support. Analysts suggest the move could also serve to ease pressure on Iran, allowing the country to avoid direct involvement in the broader Gulf crisis. Harrer described the action as an informal entry into the ongoing Gulf conflict, noting that although the Houthis have not officially declared war on the United States, their actions now place them more deeply within the larger geopolitical struggle. U.S. President Donald Trump stated during a meeting with Lebanese President Joseph Aoun in Washington that there had been no prior blockade by the Houthis. “We haven’t heard anything from them for a long time,” he remarked. “If it happens, we’ll take care of it.” He cited previous U.S. military actions against the Houthis, including air strikes in Yemen earlier this year. However, Harrer cautioned that the U.S. may find it difficult to respond effectively. She pointed out that the U.S. does not possess unlimited military resources and that the Houthis are often underestimated. “They have taken over parts of the Yemeni military and are well-equipped,” she explained.
