The Iran-backed Houthis have threatened to close or disrupt navigation through the Bab al-Mandeb Strait, targeting oil tankers and other maritime traffic [1, 2, 3].

This threat places a critical global trade artery at risk, as any prolonged closure could destabilize international energy markets and increase shipping costs for Western nations.

The Houthis issued these warnings over a period of about two weeks [1]. The group said the move is intended to pressure Saudi Arabia and its allies, while retaliating against what they describe as a siege and alleged attacks on Iranian interests [1, 2].

Iranian officials reportedly requested that the Houthis prepare to disrupt the flow of oil tankers through the Red Sea if the U.S. targets Iranian power grids or energy facilities [2].

The strategic importance of the strait is significant. Approximately seven million to 10 million barrels of oil pass through the waterway daily [4]. Additionally, between 12 percent and 15 percent of international trade destined for the U.S., Europe, and other markets flows through this corridor [4].

The Saudi-led Arab coalition responded to these threats on July 4, 2024. The coalition said it would strike with "unprecedented force" in response to any attempts to target the kingdom, its national capabilities, or violations of Yemeni sovereignty [1].

While the Houthis have signaled their intent to block the waterway, some analysts suggest the scale of daily traffic makes a total closure extremely difficult to maintain [1, 4].

“The Houthis have threatened to close or disrupt navigation through the Bab al-Mandeb Strait.”

The Bab al-Mandeb Strait is a narrow chokepoint that connects the Red Sea to the Gulf of Aden. Because such a high volume of global energy and commercial goods depends on this passage, the Houthis are using the threat of maritime disruption as geopolitical leverage. This escalation highlights the interconnectedness of Middle Eastern regional conflicts and global economic stability, where local skirmishes can trigger worldwide price spikes in oil and shipping.
