The global economy faces a potential unprecedented disruption as Iran reportedly prepares to coordinate with Houthi rebels to close the Bab al-Mandab Strait, potentially creating a dual-chokepoint crisis alongside the Strait of Hormuz. According to reports from Reuters and The Telegraph, Tehran has communicated a potential closure strategy to the Houthis, which would be triggered if the United States targets Iranian energy or transport infrastructure.
The Strategic Importance of Global Maritime Chokepoints
The world’s energy security relies heavily on two narrow waterways. The Strait of Hormuz is the conduit for approximately a fifth of the world’s oil and gas trade. In contrast, the Bab al-Mandab Strait—which connects the Indian Ocean to the Suez Canal—handles roughly a tenth of global maritime trade and serves as a primary artery between Asia and Europe. Combined, these passages are essential for about one-third of the world’s seaborne oil shipments, according to industry data.

Analysts and Iranian officials have described these maritime chokepoints as an “economic nuclear weapon.” Controlling these routes allows regional actors to exert significant leverage over global commodity prices and international trade logistics.
The Escalation Between Washington and Tehran
The current threat follows a period of heightened rhetoric between the U.S. and Iran. Following a warning from U.S. President Donald Trump, who stated in an interview with Fox News that the U.S. would target Iranian power plants and bridges if the country does not negotiate, the risk of a retaliatory maritime blockade has increased. Reuters reports that high-level Iranian sources have discussed the closure of the Bab al-Mandab Strait as a direct response to potential U.S. military strikes on Iranian infrastructure.
The Houthis appear to be operationally prepared for such a scenario. Sources cited by Reuters indicate that the group has already positioned drones and missiles in the vicinity of the Bab al-Mandab coast. One regional source noted that sophisticated technology is not strictly required to halt shipping, as even basic firearms can disrupt maritime traffic in such narrow passages.
Economic Consequences of a Dual-Strait Blockade
The potential for a simultaneous closure of both the Strait of Hormuz and the Bab al-Mandab would be unprecedented. Historical data suggests the volatility such a move would trigger. When Iran effectively closed the Strait of Hormuz on February 28 following joint U.S.-Israeli strikes, the prices of oil, fertilizers, and other essential commodities surged.
The market impact is already visible. Brent crude, which traded around $73 per barrel in late June, climbed to approximately $86 within two weeks following the latest escalation. Analysts consulted by Reuters suggest that if the conflict deepens and both straits become compromised, prices could breach the $100-per-barrel threshold. This would not only inflate fuel costs but also drive up expenses across the global logistics and supply chain sectors.
Comparison: Previous Disruptions vs. Potential Future Trends
| Strait | Primary Risk | Historical Impact |
|---|---|---|
| Hormuz | Oil/Gas export stoppage | Sharp price spikes in energy |
| Bab al-Mandab | Logistics/Trade delays | Rerouting around Africa |
Frequently Asked Questions
What happens if the Bab al-Mandab is closed?
Shipping companies would be forced to reroute vessels around the southern tip of Africa. This adds weeks to transit times and significantly increases operational costs for goods moving between Asia and Europe.
Why are these straits considered “economic weapons”?
Because they are narrow, high-traffic corridors, they are difficult to defend and easy to obstruct. Disrupting them forces a global supply chain reaction that immediately impacts energy prices and inflation.
Is the U.S. currently involved in maritime restrictions?
Yes. The U.S. has renewed a naval blockade of ships traveling to and from Iranian ports to limit Iranian trade capabilities.
