What to Know About the Bab El-Mandeb Strait as Iran Threatens to Restrict Other Key Trade Passage

Why It Matters

A closure would choke a vital conduit for oil, LNG, and essential commodities, driving global price spikes and supply‑chain disruptions. The threat underscores how regional proxy wars can quickly translate into worldwide economic risk.

Key Takeaways

• Bab el-Mandeb moves ~4.2 million barrels of oil daily (2025).
• Iran threatens closure via Houthi proxies, echoing Hormuz tactics.
• Maersk paused Trans‑Suez sailings through Bab el‑Mandeb for security.
• Potential shutdown could spike oil, LNG, wheat and fertilizer prices globally.

Pulse Analysis

The Bab el‑Mandeb Strait, often called the "Gate of Tears," is a narrow 18‑mile passage that funnels roughly 4.2 million barrels of crude and petroleum products each day. Its strategic position between the Red Sea and the Gulf of Aden makes it a critical alternative route for oil that cannot pass through the Strait of Hormuz, especially for Saudi crude rerouted via the East‑West pipeline and Russian shipments bound for Asian markets. Recent security alerts have already prompted major carriers like Maersk to suspend Trans‑Suez voyages, highlighting the strait’s vulnerability to geopolitical pressure.

Iran’s recent rhetoric, amplified by advisers to the Supreme Leader and the Iranian parliament speaker, signals a willingness to weaponize the Bab el‑Mandeb through its Houthi allies in Yemen. While Tehran lacks a direct naval presence near the chokepoint, it can supply the Houthis with weapons, financing, and strategic guidance, enabling them to threaten or disrupt traffic with anti‑ship missiles and drones. The Houthis have demonstrated this capability since 2023, targeting vessels linked to Israel, the United States, and the United Kingdom, and their potential escalation could mirror the 2024 Hormuz closure that sent Brent crude soaring above $115 per barrel.

A shutdown or sustained disruption would reverberate across global markets. Insurance premiums for vessels transiting the Red Sea would rise sharply, prompting shippers to seek longer, costlier routes around Africa’s Cape of Good Hope. Commodity prices—particularly oil, liquefied natural gas, wheat, rice, and fertilizers—could experience sudden spikes, pressuring economies already grappling with energy inflation. Policymakers in the United States and Europe are therefore monitoring diplomatic channels closely, weighing naval deployments and multilateral sanctions to deter proxy aggression and preserve the flow of trade through this indispensable maritime artery.
