Houthis Consolidate Grip on Bab al-Mandeb as Coastal Takeover Stirs Regional and Maritime Alarm

Houthi forces have finalized their control over Yemen’s entire Red Sea coastline following a swift weekend military offensive that saw the capture of the key port city of Mocha and the strategic island of Mayyun, also known as Perim. The territorial advance cements the group’s hold over the vital coastal perimeter, establishing a formidable presence directly overlooking one of the most critical maritime transit corridors in the world.

With these recent acquisitions, Houthi fighters are now stationed just 20 kilometres (12 miles) across the water from the African continent. This positioning effectively places the strategically vital Bab al-Mandeb strait—a narrow gateway connecting the Red Sea to the Gulf of Aden and the wider Indian Ocean—under the direct operational purview of the Yemeni armed movement.

Although there are no current indications that Houthi operations will spill beyond the borders of Yemen, the immediate ramifications of the offensive are already impacting neighbouring East Africa. The International Organisation for Migration reported on Sunday that more than 2,000 Yemeni civilians fled across the maritime divide to Djibouti within a 24-hour window.

Most of these displaced individuals have arrived in the coastal city of Obock, situated roughly 20 kilometres opposite Yemen’s shoreline. While humanitarian agencies have mobilized to supply arriving refugees with essential food and clean water, the International Organisation for Migration cautioned that greater international assistance and resources will be necessary to manage the unfolding displacement crisis.

The strategic significance of the Bab al-Mandeb strait cannot be overstated for global commerce and energy security. The waterway normally accommodates roughly 12 percent of total global trade, facilitating the passage of approximately 11 percent of seaborne crude oil and 8 percent of worldwide liquefied natural gas shipments.

The consolidation of Houthi authority over this maritime chokepoint coincides with heightened geopolitical tensions across the Middle East. Iran, an ally of the Houthis, maintains substantial control over the Strait of Hormuz, an energy artery that accommodated nearly a fifth of international petroleum supplies prior to the outbreak of the war launched by the United States and Israel against Iran on February 28. While Tehran maintains that its Yemeni partners operate independently, global supply chains remain acutely sensitive to simultaneous instability across both critical waterways.

Publicly, Houthi officials have sought to downplay concerns regarding international maritime transport. Hazem al-Assad, a member of the Houthi political bureau, insisted that commercial navigation and global trade moving through the Red Sea and Bab al-Mandeb would remain secure and orderly. Nevertheless, international shipping conglomerates have responded to the latest military developments with extreme caution.

These industry concerns stem from ongoing security incidents on the water, where vessels linked to Saudi Arabia have faced targeting in recent weeks despite official reassurances. The current climate follows an extended campaign between November 2023 and mid-2025 during which Houthi forces launched attacks against more than 100 merchant ships suspected of having affiliations with Israel or its international allies.

Maritime security analysts point out that the group’s physical control of the coastline significantly alters local tactical dynamics. Alexandru Cristian Hudisteanu, a former naval officer and maritime security specialist, observed that the Bab al-Mandeb strait is considerably narrower than the Strait of Hormuz. He noted that while coastal territorial gains do not fundamentally transform the Houthis' overall military capabilities, occupying the shoreline makes the process of targeting passing vessels far simpler.

This tactical advantage was recently highlighted in video footage featuring a local Houthi commander along the coast, who stated that conventional ground artillery could now be stationed in the area to target naval and commercial traffic in adjacent waters.

The prolonged friction in the waterway has already imposed heavy tolls on international shipping patterns. According to data compiled by IMF PortWatch, overall container volume and vessel tonnage passing through the Red Sea plummeted by 50 to 55 percent between 2023 and 2025 following earlier rounds of maritime strikes. Major cargo operators responded by diverting their fleets around Africa’s Cape of Good Hope, a costly alternative that adds upwards of 20 days to voyages and substantially elevates global freight rates.

This widespread abandonment of the Red Sea route has dealt a severe blow to Egypt’s economy, which depends heavily on Suez Canal transit fees for crucial foreign exchange earnings. Official records show that Egypt sustained approximately $7 billion in financial losses between 2023 and 2024, representing an estimated 60 percent drop in overall Suez Canal revenues.

Hudisteanu noted that the economic scarring remains difficult to reverse, explaining that a significant portion of international shipping ceased using the corridor altogether during previous escalations. Even after previous anti-shipping operations were paused and promises of safe transit were issued, numerous transport firms chose to maintain their extended Cape of Good Hope detours rather than risk returning.

Compounding the problem are structural and diplomatic limits facing international naval operations. The European Union-led Operation Atalanta task force remains deployed in the region to safeguard maritime commerce, and various global powers, including the United States and China, frequently utilize logistics facilities in Djibouti. However, Hudisteanu explained that strict mission mandates and bureaucratic sluggishness hinder multinational forces from rapidly adjusting their operational scope to counter emerging threats, creating an appearance of inactivity that can inadvertently embolden local actors.

The concentration of international naval power near Bab al-Mandeb and the Strait of Hormuz amid regional conflict has generated unintended secondary risks across the Horn of Africa. Maritime security experts have documented an operational vacuum along the Somali coastline, which organized criminal enterprises have leveraged to orchestrate a resurgence in regional piracy as Western and allied warships remain preoccupied with guarding primary military chokepoints.
