New Hormuz Vessel Strike Deepens Shipping Risk

13 September 2026

Executive Summary

The security situation in the Strait of Hormuz has deteriorated again after a commercial vessel was struck by a projectile early Sunday, adding another direct attack on shipping inside the world’s most important oil-transit chokepoint.

UK Maritime Trade Operations reported that a vessel had been hit by an unknown projectile while transiting the Strait.

Separately, Iranian state media reported that an Iranian commercial vessel was struck near Qeshm Island.

Iranian reporting said at least one person was killed and several others injured.

It is not yet completely clear whether the UKMTO report and the Iranian report refer to the same incident.

That distinction matters.

The responsible party has also not been independently established.

What is clear is that commercial vessels continue to suffer physical attacks inside the Strait while traffic remains severely disrupted.

This comes immediately after:

• Saudi Arabia temporarily shut its East-West oil pipeline following a drone attack.
• Houthi forces seized strategic Perim Island in Bab el-Mandeb.
• Gulf shipping continued operating at substantially reduced levels.

Iran is also preparing proposals concerning future management of Hormuz transit, including conditions for reopening and potential controls over passage.

No agreement has been reached.

The risk is therefore shifting beyond temporary disruption towards uncertainty over the future operating rules governing one of global trade’s most important waterways.

UK Impact

UK companies may experience consequences through:

• Marine war-risk premiums.
• Higher freight rates.
• Vessel delays.
• Oil-price volatility.
• Diesel costs.
• LNG-price volatility.
• Petrochemical costs.
• Supplier surcharges.
• Longer lead times.
• Inventory requirements.
• Contractual delivery disputes.

Businesses should be particularly careful when relying upon general statements that Hormuz remains “open”.

A route may technically remain navigable while individual:

• Owners.
• Charterers.
• Insurers.
• Flag states.
• Crews.

decide that particular voyages are no longer commercially acceptable.

That can reduce effective shipping capacity without any formal closure.

Global Impact

Before the conflict, approximately 15 million barrels of Persian Gulf oil travelled through Hormuz each day.

Alternative infrastructure has helped mitigate disruption.

But those alternatives are themselves under increasing pressure.

Saudi Arabia’s East-West pipeline was designed partly to bypass Hormuz.

That pipeline has now suffered an attack.

Red Sea exports depend upon access through Bab el-Mandeb.

Houthi forces now hold Perim Island inside that Strait.

This creates a particularly difficult risk structure.

The alternative routes designed to protect global energy supply are themselves becoming exposed to conflict.

Meanwhile, uncertainty over any new Iranian transit regime could create legal and operational difficulties concerning:

• Navigation rights.
• Transit fees.
• Vessel screening.
• Sanctions.
• Naval protection.
• Insurance requirements.

Our View

Businesses with Gulf exposure should now consider both physical security and potential changes in the regulatory environment surrounding passage.

Companies should ask:

• Has the carrier reconfirmed the voyage?
• Has the insurer changed its conditions?
• Has the war-risk premium increased?
• Who pays additional premium?
• Could the vessel be rerouted?
• Is the alternative route genuinely safer?
• Does the contract permit deviation?
• Would a new transit-fee regime affect voyage economics?
• Could compliance with one authority conflict with another?
• Could sanctions prohibit payment of transit charges?
• Are additional inventory levels required?
• Can critical inputs be sourced outside the Gulf?
• Are fuel surcharges capped?
• Does force majeure address military interference?
• Could delivery delays create downstream contractual penalties?
• Are suppliers financially resilient enough to absorb continuing disruption?

The key issue is no longer simply whether the Strait can physically be crossed.

Businesses increasingly need to understand:

who controls the passage, under what conditions, at what cost and with what level of insurance protection.
