Houthi forces have seized complete control of Yemen’s Red Sea coastline following the capture of the port city of Mocha and the strategic island of Mayyun over the weekend. The territorial sweep brings the group into effective command of the Bab al-Mandeb strait, one of the most critical maritime chokepoints in the world.
By establishing positions along the western coast, Houthi fighters are now located approximately 20 kilometres (12 miles) across from the African continent. The rapid advance has raised immediate alarm across neighbouring nations, presenting an economic bottleneck for Egypt, security challenges for Sudan and Somalia, and shifting strategic leverage for coastal neighbours like Djibouti and Eritrea.
The regional impact of the fighting was felt immediately across the water in East Africa. According to the International Organisation for Migration (IOM), more than 2,000 people crossed the narrow waters from Yemen into Djibouti within a single 24-hour window over the weekend.
Displaced individuals arriving in Obock, a coastal settlement in Djibouti situated just 20 kilometres from Yemen, have been receiving emergency food and drinking water. However, the IOM has warned that current resources are stretched thin and that greater international support is urgently needed to manage the unfolding humanitarian influx.
The territorial takeover places immense pressure on international commerce, as the Bab al-Mandeb strait normally facilitates approximately 12 percent of total global trade. The narrow maritime corridor also serves as a vital transit lane for energy markets, carrying roughly 11 percent of seaborne oil and 8 percent of global liquefied natural gas (LNG).
The developments coincide with broader regional tensions, as the Houthis' ally, Iran, maintains leverage over the Strait of Hormuz. That waterway handled roughly one-fifth of global energy transit before the outbreak of conflict involving the United States, Israel, and Iran on February 28.
In response to international apprehension, Houthi politburo member Hazem al-Assad maintained that international trade and navigation through the Red Sea and the Bab al-Mandeb remain orderly and safe. Concurrently, Tehran has asserted that the Houthi movement operates as an independent force. Despite these official statements, commercial shipping companies continue to approach the waterway with deep caution.
Maritime security specialist and former naval officer Alexandru Cristian Hudisteanu noted that the Bab al-Mandeb is physically narrower than the Strait of Hormuz. While the territorial acquisition does not fundamentally change the Houthis' overall military capabilities, Hudisteanu explained that controlling the coastline simplifies their ability to target commercial vessels passing through the strait.
Evidence of this increased tactical advantage was highlighted by footage of a Houthi commander on the coast, who claimed that artillery units could easily be stationed along the shoreline to strike maritime targets within the surrounding waters.
Commercial maritime data reflects the enduring toll that regional instability has taken on transit lanes. According to figures from IMF PortWatch, shipping volume and cargo tonnage traversing the Red Sea dropped by 50 to 55 percent between 2023 and 2025 during previous waves of Houthi strikes on commercial shipping.
Because of the ongoing risks, major maritime carriers have continuously redirected their vessels away from the Red Sea, routing them around Africa’s Cape of Good Hope instead. This southern diversion tacks on more than 20 days of voyage time and continues to drive up global freight rates significantly.
Efforts by foreign navies to protect commercial vessels also face operational constraints. The European Union-led Operation Atalanta task force maintains a security mission in the Red Sea, and international navies—including those of the United States and China—frequently utilize Djibouti as a port of call to coordinate regional logistics.
However, Hudisteanu pointed out that ships deployed under existing missions operate under strictly defined mandates. Bureaucratic delays in updating operational rules make it difficult for naval vessels to respond outside their original scope, creating periods of inactivity that risk sending the wrong signal to regional actors.
The concentration of naval forces toward the Bab al-Mandeb and the Strait of Hormuz has also produced unintended security side effects along the Horn of Africa. Hudisteanu warned that the redeployment of international warships has left strategic vacuums that organized maritime criminals and Somali pirates have actively exploited.
The disruption in maritime traffic poses particularly severe economic repercussions for Egypt, which depends heavily on Suez Canal transit fees for foreign currency. Egyptian authorities recorded a loss of approximately $7 billion between 2023 and 2024, representing an estimated 60 percent decline in Suez Canal revenues.
Despite renewed assurances from Houthi officials regarding navigational safety, recent attacks against Saudi-linked vessels have perpetuated high levels of risk. Between November 2023 and mid-2025, the group targeted more than 100 commercial ships that it asserted had connections to Israel or its allies. As Hudisteanu observed, even after previous campaigns ceased and statements of safety were issued, many shipping companies opted not to return to the Red Sea, choosing the longer Cape route instead.
