Iran's Threats Against This Red Sea Choke Point Are a Big Vulnerability for the Oil Market

Why It Matters

Disrupting the Bab el‑Mandeb would remove a critical relief valve for oil flows, tightening global supply and pressuring prices at a time of heightened geopolitical risk.

Key Takeaways

• Iran threatens to close Bab el‑Mandeb if Israel continues Gaza strikes
• Saudi rerouted ~7.2 m bpd through Red Sea, doubling February volumes
• Crude prices jumped 8% on the threat, showing market sensitivity
• Houthis could target specific tankers, further deterring Bab el‑Mandeb traffic

Pulse Analysis

The Bab el‑Mandeb Strait has become the oil market’s emergency outlet since the Strait of Hormuz saw a sharp decline in traffic after Iranian attacks. By linking the Red Sea to the Gulf of Aden, the passage enables Saudi Arabia to pump millions of barrels daily through its East‑West pipeline, bypassing the Persian Gulf entirely. This logistical flexibility has helped sustain supply to Asian refiners, especially Japan and South Korea, and has kept the global price curve from spiking as dramatically as it did during earlier Gulf disruptions.

Geopolitical calculations now hinge on Tehran’s willingness to weaponize the strait. Iran’s Revolutionary Guard has tied the Bab el‑Mandeb’s openness to Israel’s actions in Gaza and Lebanon, while Hezbollah’s ambiguous stance adds another layer of uncertainty. Meanwhile, the United States maintains a naval presence to deter both Iranian and Houthi interference, but the recent exchange of fire in the Hormuz corridor signals that escalation remains a real possibility. Saudi Arabia’s reliance on the Red Sea route underscores the broader regional power shift, where Gulf states diversify export pathways to hedge against single‑point failures.

For traders and risk managers, the scenario translates into heightened volatility and a premium on geopolitical intelligence. An abrupt closure would instantly cut off roughly 7 million barrels per day, tightening global inventories and likely pushing Brent and WTI into double‑digit gains. Market participants are therefore monitoring diplomatic channels, naval deployments, and any sign of coordinated Houthi attacks, as even limited disruptions could reverberate through futures markets and reshape supply‑demand forecasts for the remainder of the year.
