Iran Signals Possible Bab el-Mandeb Closure, Raising Red Sea Risk as Hormuz Remains Shut

Iran’s reported instruction to Yemen’s Houthi movement to prepare for a possible closure of the Bab el-Mandeb Strait adds a new layer of risk to already‑stressed maritime trade, with the Strait of Hormuz effectively shut and U.S.–Iran strikes escalating. Any disruption at Bab el-Mandeb would choke a second critical energy and container route, driving up freight, insurance and potentially commodity prices. Traders now face a scenario of simultaneous pressure on both of the Middle East’s main export gateways.

Iran–Houthi Bab el-Mandeb Threat Intensifies Chokepoint Crisis as Hormuz Stays Shut

Introduction

Iran has asked Yemen’s Houthi movement to stand ready to close the Bab el-Mandeb Strait if the United States carries out airstrikes on Iranian power infrastructure, according to multiple reports citing sources familiar with the discussions. The Houthis have reportedly deployed missiles and drones near the Red Sea gateway and are awaiting a potential order, with Iranian Revolutionary Guard officers in Yemen said to oversee the timing of any move.

The development comes as the Strait of Hormuz remains effectively closed amid the ongoing war between Iran, the United States and regional allies, following repeated attacks on shipping and a reimposed U.S. maritime blockade on Iranian ports. Together, Hormuz and Bab el‑Mandeb anchor key routes for Middle Eastern oil, oil products, LNG, fertilizers and containerized goods. A second chokepoint crisis in the Red Sea would therefore have significant implications for global energy and agricultural commodity markets.

Immediate Market Impact

The reported Bab el-Mandeb threat is already sharpening risk premia around Middle Eastern shipping. Iran’s earlier closure of Hormuz, through which roughly a fifth of pre‑war global oil and gas seaborne trade moved, has pushed crude benchmarks higher and forced rerouting of cargoes. Any move to restrict Bab el‑Mandeb would constrain an additional 7–10% of global seaborne oil and significant volumes of refined products and containers transiting between the Indian Ocean and Suez.

For agricultural commodities, the Red Sea corridor is a major artery for Black Sea, European and South American grains heading to the Middle East, East Africa and South Asia, and for Asian exports into Europe. A heightened threat environment – even without a full closure – typically leads to higher war‑risk insurance premiums, longer routes via the Cape of Good Hope, and tighter vessel availability. These cost pressures are likely to translate into higher CIF prices and greater basis volatility across wheat, corn, soy, sugar and edible oils flows that rely on Suez–Red Sea passages.

Supply Chain Disruptions

A closure or sustained attack campaign around Bab el-Mandeb would disrupt transit between the Red Sea and Gulf of Aden, effectively severing the shortest sea link between Asia and Europe at a time when traffic through Hormuz is already curtailed. Carriers previously re‑routed ships around the Cape of Good Hope during earlier Houthi attacks linked to the Gaza conflict; a renewed and more formalized threat could lock in these deviations and strain global shipping capacity.

Key risks include port congestion at alternative hubs, longer voyage times for tankers and bulkers, and potential temporary suspensions of service to high‑risk ports on the Red Sea littoral. Saudi Arabia has already redirected a larger share of its exports via the Red Sea port of Yanbu to mitigate Hormuz exposure; that strategy becomes more fragile if Bab el‑Mandeb is threatened, compounding risk for both crude and product supply chains.

Import‑dependent regions such as North and East Africa, the Arabian Peninsula and parts of South Asia are particularly exposed due to their reliance on Red Sea routes for fuel and food staples. Any sustained disruption would likely trigger inventory draws, opportunistic stock‑building where logistics allow, and potential government interventions in freight or food import programs to secure supplies.

Commodities Potentially Affected

• Crude oil and refined products – Both Hormuz and Bab el-Mandeb are core to Middle Eastern export flows; simultaneous disruption would tighten global availability, elevate freight and insurance costs and widen regional price differentials.
• LNG and LPG – Gas cargoes moving from Qatar and other Gulf producers to Europe and Asia rely on Hormuz and often Suez; rerouting around Africa increases transit time and reduces prompt supply flexibility.
• Wheat and coarse grains – Shipments from the Black Sea, Europe and the Americas to the Middle East and East Africa commonly transit Suez and the Red Sea; added distance and risk premia could raise delivered grain costs for import‑reliant countries.
• Oilseeds and vegetable oils – Soybeans, meal and palm oil flows between Asia, Europe and the MENA region depend on this corridor; disruptions may alter crush margins and inter‑regional arbitrage.
• Sugar and coffee – Brazilian and Asian flows into the Mediterranean and European markets could face longer voyages and higher freight, impacting delivered prices and potentially shifting refining margins and destination preferences.
• Containerized food and feed ingredients – Processed foods, dairy ingredients, feed additives and packaging moving Asia–Europe via Suez would see higher transit times and logistics costs, pressuring downstream food manufacturers’ input costs.

Regional Trade Implications

Major Middle Eastern exporters such as Saudi Arabia, the UAE, Kuwait and Iraq face constrained routing options with Hormuz shut and Bab el‑Mandeb potentially at risk, limiting their ability to redirect volumes without incurring substantial cost and delay. This could support price premiums for Atlantic Basin barrels and non‑Middle Eastern crude and products, benefitting exporters in the Americas, West Africa and the North Sea who can supply Europe without transiting the contested chokepoints.

On the import side, Europe may lean more heavily on U.S., Brazilian and West African supply for both energy and agricultural commodities, while some Asian buyers could seek to diversify toward Pacific and Russian origins where sanctions and logistics allow. MENA food‑importing states with Red Sea ports, notably Egypt and countries in the Horn of Africa, are vulnerable to freight spikes and disruption; they may step up use of overland routes or alternative ports where possible, though capacity is limited.

Market Outlook

In the short term, markets are likely to price in a higher geopolitical risk premium as traders assess the probability that U.S. infrastructure strikes on Iran trigger an actual move against Bab el‑Mandeb. Iran’s signaling appears designed to deter such attacks by raising the potential economic cost for the United States and its partners, but it simultaneously raises uncertainty for shipowners, insurers and commodity buyers.

Volatility in crude benchmarks, tanker and bulker freight indices, and selected agricultural futures linked to Black Sea and Middle Eastern trade routes can be expected as participants reposition. Key variables to monitor include any confirmed attacks on shipping near Bab el‑Mandeb, adjustments in naval escorts and insurance classifications for the Red Sea, and signs of accelerated stock‑building by major importers.

CMB Market Insight

The emerging Bab el-Mandeb risk, layered on top of the existing Hormuz closure, represents a potential step‑change in chokepoint exposure for global commodity trade rather than a localized security flare‑up. For energy and agricultural markets alike, the critical question is whether the threat remains a bargaining tool or translates into sustained kinetic disruption of shipping lanes.

Commodity buyers, producers and logistics providers should stress‑test supply chains for extended diversions around Africa, reassess counterparty and route risk, and consider opportunistic hedging of freight and key raw materials sensitive to Red Sea and Hormuz traffic. In the coming days, positioning will hinge less on underlying demand shifts and more on headline risk from the Gulf and Red Sea – making real‑time monitoring of maritime incidents and policy signals central to trading and procurement decisions.
