What Is the Bab el-Mandeb Strait? Why Iran's Latest Threat Could Shake the Global Economy

The Bab el-Mandeb Strait, often called the "Gate of Tears," has emerged as one of the world's most closely watched waterways after Iran and its Houthi allies signaled it could become the next major flashpoint in the escalating Middle East conflict.

After disrupting shipping through the Strait of Hormuz, Tehran is now threatening to extend pressure to the Bab el-Mandeb, a narrow maritime corridor linking the Red Sea to the Gulf of Aden. Analysts say that if both waterways were disrupted simultaneously, the impact on global oil supplies, shipping and inflation could be severe, according to Reuters.

The renewed focus on the strategic chokepoint comes as U.S. strikes inside Iran intensify and Houthi attacks in the Red Sea continue, raising fears that the conflict could spread beyond the Persian Gulf and into another of the world's busiest commercial shipping routes.

Why the Bab el-Mandeb Matters

Located between Yemen on the Arabian Peninsula and Djibouti and Eritrea in the Horn of Africa, the Bab el-Mandeb serves as the southern gateway to the Red Sea and the Suez Canal.

The strait is one of the world's most important maritime chokepoints because it carries millions of barrels of crude oil, petroleum products and liquefied natural gas every day, along with thousands of cargo ships transporting consumer goods between Asia and Europe.

If vessels cannot safely transit the Bab el-Mandeb, they must sail around the Cape of Good Hope at the southern tip of Africa, adding thousands of miles to shipping routes, increasing transportation costs and delaying deliveries worldwide.

Its Arabic name translates to "Gate of Tears," reflecting the dangerous waters that have challenged sailors for centuries.

The Bab el-Mandeb Strait — just 30 kilometers wide at its narrowest — links the Red Sea to the Gulf of Aden, forming the southern gateway to the Suez Canal. It’s a critical artery of global commerce, where ships carrying oil, gas, and goods between Asia and Europe pass every day. Nearly 12 percent of the world’s maritime trade flows through this narrow stretch between Yemen, Djibouti, and Eritrea. Yet despite its immense importance, the Bab el-Mandeb often slips under the radar — until conflict or disruption reminds the world how much depends on this fragile link between continents. #BabElMandeb #RedSea #MaritimeTrade #GlobalShipping #Geopolitics

Iran Signals a New Pressure Point

Iran appears ready to use the Bab el-Mandeb as another strategic lever in its confrontation with Washington.

According to Reuters, Mohammed al-Farah, a member of the political bureau of Yemen's Ansarullah movement, better known as the Houthis, warned that Yemen's armed forces could close the Bab el-Mandeb if Saudi Arabia continued military operations against Yemen.

"If the current situation aggravates, the Bab el-Mandeb Strait and the Strait of Hormuz will be closed in an operational alliance," al-Farah said, adding that oil prices could surge to as much as $200 per barrel.

The statement suggests Tehran may be prepared to coordinate pressure on both of the world's most strategically important energy corridors simultaneously.

Middle East scholar Fawaz Gerges told Reuters that the move is intended to demonstrate Iran's ability to widen the conflict beyond the Persian Gulf.

"Iran is willing to go all the way," Gerges said. "Now (Tehran) is escalating both near and wide. The message is that not only Hormuz, but Bab al-Mandab, is at risk."

The Houthis Have Done It Before

The threat is not merely theoretical.

Following the outbreak of the Israel-Hamas war in October 2023, the Iran-backed Houthis launched dozens of attacks against commercial vessels transiting the Red Sea, saying they were targeting ships linked to Israel in support of Palestinians in Gaza.

Those attacks forced many of the world's largest shipping companies to reroute vessels around southern Africa, significantly increasing shipping costs and disrupting global supply chains. The campaign also prompted U.S. and British airstrikes against Houthi targets and the deployment of a multinational naval force to protect commercial shipping.

Could It Trigger a Larger War?

Analysts say Iran is unlikely to close the Bab el-Mandeb unless it concludes that broader conflict is unavoidable.

Andreas Krieg, a senior lecturer at King's College London's School of Security Studies, described the move as another "nuclear option" available to Tehran after Hormuz.

He warned that further U.S. strikes against Iran's critical infrastructure could prompt Tehran to activate its Yemeni allies, compounding the economic shock already created by disruptions in the Strait of Hormuz.

Abdulaziz Sager, chairman of the Saudi-based Gulf Research Center, said Gulf nations increasingly believe diplomacy with Iran has reached its limits but cautioned that the Houthis are unlikely to escalate significantly without direct orders from Tehran.

He added that any sustained attempt to block the Bab el-Mandeb would likely trigger a broader military response from the United States and its allies.

For now, the "Gate of Tears" remains open. But as fighting spreads across the Middle East, analysts warn that this narrow waterway has become one of the world's most important geopolitical pressure points, with consequences that could ripple through global energy markets, supply chains and the international economy.
