Houthi Involvement in the Iran War: Implications for Global Trade and Energy Supply

Escalation of Conflict in the Bab al-Mandeb Strait
The recent entry of Yemen's Iran-aligned Houthi rebels into the ongoing Iran war has raised significant concerns regarding the stability of the Bab al-Mandeb Strait, a crucial maritime chokepoint linking the Red Sea to the Gulf of Aden. This strait is vital for global shipping, accounting for approximately 10-12% of the world's oil and natural gas shipments, as well as container and bulk cargo traffic between Asia and Europe. The Houthis have a history of targeting commercial vessels in this region, which could exacerbate the already strained global energy supply chain.
Houthi Attacks and Regional Dynamics
On March 28, 2026, the Houthis launched ballistic missiles at Israeli military sites, marking their first direct involvement in the conflict since the US-Israeli war against Iran began. This action has prompted fears of renewed attacks on shipping in the Bab al-Mandeb Strait, especially as the Strait of Hormuz remains largely closed due to ongoing hostilities. The Houthis' military spokesman, Yahya Sare’e, indicated that their operations would continue until what they term "aggression" ceases across the region.
The Houthis' strategic positioning near the Bab al-Mandeb enhances their ability to disrupt maritime traffic, which has already been affected by previous attacks on over 100 vessels between November 2023 and January 2025. Analysts warn that if the Bab al-Mandeb were to be closed alongside the Strait of Hormuz, global shipping companies would face significant delays and increased costs, as vessels would need to reroute around Africa's Cape of Good Hope, adding thousands of nautical miles to their journeys.
Economic Impact and Global Repercussions
The potential closure of the Bab al-Mandeb Strait could lead to a drastic increase in oil prices and shipping costs, further straining an already fragile global economy. Current estimates suggest that the closure could result in a deficit of approximately 16 million barrels per day in global oil supply versus demand. This scenario would mirror the economic disruptions experienced during the COVID-19 pandemic, with severe implications for energy consumption and inflation worldwide.
Saudi Arabia has been relying on the Red Sea port of Yanbu and its East-West pipeline to maintain oil exports to Asia amid disruptions in the Strait of Hormuz. However, renewed Houthi attacks could jeopardize this vital route, compelling Saudi Arabia to reconsider its military strategy in the region.
Criticism and Opposition
Critics of the Houthis' involvement argue that their actions could further destabilize the region and complicate ongoing peace efforts in Yemen. The humanitarian crisis in Yemen, exacerbated by years of conflict, could worsen if the Houthis escalate their military operations. Farea Al-Muslimi, a research fellow at Chatham House, emphasized that the Houthis' entry into the broader conflict represents a serious escalation, with potential repercussions for vital economic and military infrastructure across the Gulf region.
Official Statements and Responses
In response to the escalating situation, U.S. Secretary of State Marco Rubio indicated that the U.S. expects to conclude military operations in the region within weeks, while also acknowledging the need for international cooperation to secure maritime routes. The U.S. and its allies have previously established Operation Prosperity Guardian to protect vessels in the Red Sea, but the effectiveness of these measures remains uncertain as tensions rise.
What's Next?
As the conflict continues to unfold, the international community is closely monitoring the situation in the Bab al-Mandeb Strait. The potential for increased Houthi attacks on shipping could lead to a significant escalation in the conflict, with far-reaching implications for global trade and energy security. The Houthis' strategic calculations will likely weigh their military ambitions against the need to maintain local legitimacy and avoid further entanglement in the war.
