Houthi Advance Threatens Bab el-Mandeb Shipping

11 September 2026

Executive Summary

The risk to Red Sea shipping has materially escalated after Iran-aligned Houthi forces seized the strategic Yemeni port of Mocha and advanced towards the approaches to the Bab el-Mandeb Strait.

The Houthis have also reached the Hanish Islands, strengthening their position along Yemen’s Red Sea coastline.

Bab el-Mandeb is one of the world’s most important maritime chokepoints.

It links the Red Sea and Suez Canal with the Gulf of Aden and Indian Ocean and carries a substantial share of global trade and energy shipments.

The development is particularly concerning because the Strait of Hormuz remains severely disrupted.

Saudi Arabia and other Gulf exporters have increasingly relied upon Red Sea routes to move energy cargoes that might otherwise have travelled through Hormuz.

That means the international shipping system is now facing pressure at both sides of the Arabian Peninsula.

The Houthis say international navigation remains safe except for Saudi-linked shipping.

That assurance should not be treated as eliminating commercial risk.

Their territorial advance gives the group a substantially stronger physical position from which to monitor, threaten or potentially interrupt vessels approaching Bab el-Mandeb.

The United Nations has described the situation as a new and more dangerous phase in the Yemen conflict.

UK Impact

UK businesses may be exposed through:

• Container shipping.
• Oil and fuel prices.
• Marine insurance.
• War-risk premiums.
• Vessel rerouting.
• Longer Asia-Europe transit times.
• Port congestion.
• Chartering costs.
• Inventory requirements.
• Supplier delays.
• Airfreight substitution costs.
• Contractual delivery obligations.

Asia-Europe trade is particularly exposed.

If shipping companies decide that Bab el-Mandeb presents unacceptable risk, vessels may once again divert around the Cape of Good Hope.

That can add substantial voyage time and fuel consumption.

The consequences can then move rapidly into:

• Freight surcharges.
• Inventory shortages.
• Working-capital requirements.
• Higher landed costs.

Global Impact

The risk is amplified because Hormuz and Bab el-Mandeb perform different but complementary roles in global energy logistics.

Hormuz connects Gulf producers to international markets.

Bab el-Mandeb provides access from the Red Sea to the Indian Ocean and is critical to traffic using the Suez Canal.

Saudi Arabia has relied more heavily on its Red Sea export infrastructure while Hormuz has been disrupted.

If Bab el-Mandeb becomes materially less secure, that diversification route becomes significantly weaker.

Brent crude has already moved above $108 per barrel, reflecting growing concern over simultaneous disruption to multiple shipping corridors.

The danger is therefore no longer a single chokepoint failure.

It is correlated disruption across several critical maritime routes.

Our View

Businesses should now test supply chains against the possibility that both Hormuz and Bab el-Mandeb become difficult to use simultaneously.

Companies should ask:

• Does our cargo normally use Suez?
• Does it transit Bab el-Mandeb?
• Has the carrier changed its Red Sea policy?
• Would the vessel divert around the Cape?
• How many additional sailing days would that add?
• Who pays additional fuel costs?
• Who pays war-risk premiums?
• Are freight rates fixed?
• Can carriers impose emergency surcharges?
• Does marine cargo insurance remain effective?
• Are delivery commitments flexible?
• Is additional inventory required?
• Can critical cargo move by air?
• Can European sourcing replace Asian supply temporarily?
• Are alternative suppliers exposed to the same route?
• Would Saudi energy exports still reach us if both Gulf routes deteriorated?

The key risk-management lesson is particularly important:

Two alternative routes do not provide genuine resilience if both are exposed to the same regional conflict.

Businesses should now test geographic diversification at corridor level, not simply supplier level.
