Houthis seize Perim Island in Red Sea, threatening 2026 African trade routes and shipping costs

Background: the Red Sea’s strategic importance and the Houthi rise

The Red Sea is a 2,300‑kilometre artery that carries roughly 10 percent of global maritime trade, linking the Suez Canal with the Gulf of Aden. For African nations on its western shore—Kenya, Tanzania, Djibouti, and Ethiopia—the corridor is the lifeline for imports of fuel, food and manufactured goods, and for exports of coffee, tea, and minerals. Since 2015 the Iran‑backed Houthi movement has gradually expanded its naval capabilities, moving from missile strikes on Saudi oil facilities to a more sustained campaign against commercial shipping, often under the banner of “solidarity with the Palestinian cause.”

In recent months the Houthis have intensified their use of sea mines, unmanned surface vessels and small fast boats, turning the Gulf of Aden into a quasi‑war zone. Their stated goal is to pressure the Saudi‑UAE coalition that intervenes in Yemen, but the broader effect is a growing insecurity that threatens the cost and reliability of the Red Sea route—an issue that has already prompted rerouting of some container ships around the Cape of Good Hope, adding weeks to voyages and inflating freight rates.

The Perim Island seizure: what the Houthis claim

On 9 September 2026 the Houthis announced that they had taken control of Perim Island, a small landmass at the southern entrance of the Bab al‑Mandeb strait. Perim sits on the narrowest point of the strait, where the waterway narrows to just 18 kilometres, making it a natural chokepoint for any vessel passing between the Red Sea and the Gulf of Aden. The Houthi statement, broadcast on their Al‑Mouhajir TV channel, said the island’s “strategic facilities” were seized without resistance, and that a new “defensive perimeter” had been established to monitor all shipping traffic.

Independent observers, including the UK‑based maritime security firm Ambrey, have not yet been able to verify the claim on the ground, but satellite imagery released by the think‑tank Atlantic Council shows a cluster of small boats and a possible radar installation moving toward the island in the days preceding the announcement. If the Houthis are indeed operating a functional outpost on Perim, they would gain a direct line of sight over both sides of the strait, allowing them to coordinate attacks, lay mines, or demand tolls from passing vessels.

Immediate maritime implications for global and regional trade

The seizure of Perim could force shipping companies to treat the Bab al‑Mandeb as a high‑risk zone, similar to the earlier piracy hotspot off Somalia. Insurance premiums for vessels transiting the strait have already risen by 35 percent since the Houthi threat intensified in 2023, according to Lloyd’s of London. A permanent Houthi presence on Perim would likely push those costs higher and could trigger a wave of rerouting through the longer Cape of Good Hope corridor, which adds an average of 10‑12 days to a Europe‑Asia voyage and raises fuel consumption by roughly 15 percent.

For African landlocked countries such as Ethiopia and South Sudan, which rely on the Port of Djibouti and the Port of Mombasa for 80 percent of their import‑export activity, any disruption to the Bab al‑Mandeb translates directly into higher prices for everything from wheat to construction materials. The African Union’s Trade and Industry Committee warned in a statement on 10 September that “sustained interference in the Red Sea could erode the competitiveness of East African ports and jeopardise regional food security.”

Ripple effects on African economies and the diaspora

Higher freight rates ripple through the supply chains of African manufacturers, many of which operate on razor‑thin margins. A study by the Kenya Institute for Public Policy Research projected that a 10 percent rise in shipping costs would shave roughly 2 percent off Kenya’s GDP growth in 2027, primarily because export‑oriented horticulture and flower farms would lose price competitiveness in European markets. Similar calculations for Tanzania’s mineral exports—especially gold and tanzanite—suggest a potential revenue loss of $150 million annually if the Red Sea bottleneck persists.

The diaspora community, especially Yemenite and broader Middle‑East expatriates in East Africa, also feels the shock. Remittance flows from Gulf states to African households often travel through the same maritime channels; any slowdown could delay cash transfers, affecting households that depend on these funds for education and health. Moreover, the security vacuum created by a Houthi foothold may embolden other non‑state actors, such as Somali militia groups, to increase their own maritime predation, further endangering the livelihoods of African fishermen who ply the waters near the strait.

What comes next: diplomatic, military and commercial responses

The United Nations Security Council is expected to convene an emergency session on 12 September to address the “escalating threat to international navigation” in the Red Sea, according to a briefing from the UN Office of Counter‑Terrorism. The United States, Britain and France have signalled a willingness to expand their naval patrols under the Combined Maritime Forces, but logistical constraints and domestic political pressures make a rapid deployment uncertain. Meanwhile, Saudi Arabia has threatened “direct military action” to retake Perim, a stance that could draw Iran deeper into the conflict if the Houthis receive Tehran’s backing.

Commercial actors are already adapting. Major shipping lines such as Maersk and MSC announced the creation of “contingency corridors” that will shift a portion of their container traffic to the Suez‑Red Sea‑Indian Ocean route via the Port of Djibouti, with a promise of guaranteed security escorts. African port authorities are also lobbying for accelerated infrastructure upgrades—particularly in Mombasa and Lamu—to accommodate larger vessels that may be forced to bypass the Bab al‑Mandeb. The coming weeks will reveal whether the Houthi claim is a tactical bluff or a new permanent fixture on the map of Red Sea geopolitics.

Quick Answers

Why is the seizure of Perim Island by the Houthis significant for African trade?
Perim controls the narrowest point of the Bab al‑Mandeb strait, so Houthi control could raise shipping costs and force rerouting, directly affecting East African ports that rely on the Red Sea for imports and exports.

What could happen to freight rates if the Houthis maintain a presence on Perim?
Insurance premiums and fuel surcharges could climb by 30‑40 percent, pushing freight rates up and potentially reducing the competitiveness of African exporters.

How are African governments responding to the new Red Sea threat?
Countries like Kenya and Tanzania are urging faster port upgrades and are coordinating with the UN and naval coalitions to secure alternative corridors and protect maritime trade.
