The Red Sea blockade threat from Houthi forces is creating a new front in the global energy crisis, potentially shutting down critical oil shipping routes and sending shockwaves through markets already strained by the Iran conflict. Understanding the stakes is essential for anyone tracking energy prices and geopolitical stability.

The Strategic Importance of Bab el-Mandeb

Yemen’s Houthi movement has threatened to close the Bab el-Mandeb strait, the southern gateway to the Red Sea. This narrow waterway is a chokepoint for about 7.4 million barrels per day (bpd) of petroleum – roughly 7% of global oil output, according to Kpler data. With the Strait of Hormuz already disrupted by Iran, the Red Sea has become the alternative outlet for Gulf oil. A simultaneous closure of both routes would be unprecedented.

How the Houthis Could Disrupt Flows

It is not clear whether the Houthis will return to direct attacks on shipping or impose a formal maritime blockade. However, even the threat has already altered trade patterns. Saudi Arabia has diverted more than 70% of its normal daily crude exports to the Red Sea port of Yanbu since the Hormuz crisis began. Ships from Yanbu heading to Europe go north through the Suez Canal; those bound for Asia go south through Bab el-Mandeb. Any disruption at either end would cascade across global supply chains.

Route Volume (June, bpd) Global Share
Bab el-Mandeb transits 7.4 million 7%
Yanbu exports (recent weeks) 4 million ~4%
Yanbu exports (year earlier) 973,000 ~1%

The data shows how dramatically the energy market has shifted. Saudi Arabia is even considering expanding its crude oil pipeline to the Red Sea coast, as reported by Reuters, to further bypass the Gulf crisis.

Key Takeaways for Energy Markets

  • Global oil prices could spike if Bab el-Mandeb is closed, as both major Middle East export routes would be blocked.
  • European and Asian buyers face the highest risk – Europe relies on Suez, Asia on Bab el-Mandeb.
  • Energy diversification efforts (pipelines, alternative routes) are accelerating but won’t provide immediate relief.
  • The US has issued a worldwide caution for American citizens, reflecting the broader geopolitical instability.

FAQ: Red Sea Blockade and Global Energy

What is the Bab el-Mandeb strait and why does it matter?

Bab el-Mandeb is a narrow strait between Yemen and Djibouti that connects the Red Sea to the Gulf of Aden. It is a critical chokepoint for oil tankers and cargo ships. About 7% of global oil output passes through it daily, making it vital for global energy security.

How would a Houthi blockade affect oil prices?

If the Houthis successfully block or disrupt shipping through Bab el-Mandeb, it would cut off a major supply route from Saudi Arabia and other Gulf states. With the Strait of Hormuz already impacted, the simultaneous closure could send crude prices sharply higher, potentially triggering a global energy crisis.

What are Saudi Arabia’s alternatives to the Red Sea route?

Saudi Arabia is expanding its crude oil pipeline from the Eastern Province to the Red Sea port of Yanbu. This pipeline can bypass the Strait of Hormuz entirely. However, its capacity is limited, and any disruption at Yanbu itself would still leave exports vulnerable to a Bab el-Mandeb closure.

How do Houthi threats relate to the broader Iran-US conflict?

The Houthis are backed by Iran and their maritime campaign is part of a wider proxy conflict. The US and allied forces have increased naval presence in the region. The worldwide caution issued by the US underscores the potential for escalation that could further destabilize energy markets.

In summary, the Houthi threat to close the Bab el-Mandeb strait represents a major risk to global energy supply. With both Middle Eastern oil exit routes under pressure, the world may face higher prices and greater volatility. Monitoring diplomatic and military developments in the Red Sea will be critical for energy traders and policymakers alike.
