Hormuz Shipping Remains Severely Disrupted

5 September 2026

Executive Summary

Commercial shipping through the Strait of Hormuz remains at severely depressed levels despite continuing efforts by carriers and energy companies to maintain Gulf trade.

Latest vessel-tracking data shows that only four commodity vessels crossed the Strait on Thursday, compared with a recent 10-day average of approximately 15.

The vessels included two medium-range tankers, a Kamsarmax bulk carrier and a Handysize vessel.

The figures do not capture vessels operating with Automatic Identification System transponders switched off, meaning actual movements may be somewhat higher.

Nevertheless, the observable traffic pattern confirms that Hormuz has not returned to anything approaching normal commercial operation.

Iran has also expanded the number of vessels it considers non-compliant with its requirements for transit through the Strait.

Ships appearing on that list may potentially face:

• Fines.
• Detention.
• Confiscation.
• Additional scrutiny.

This creates a particularly difficult environment for shipowners, charterers, cargo interests and insurers.

The waterway is not formally closed.

But neither is it operating as a predictable international shipping corridor.

The central risk is therefore prolonged restricted navigation rather than a binary open-or-closed scenario.

UK Impact

UK companies may experience the consequences through:

• Higher freight costs.
• Higher war-risk premiums.
• Oil-price volatility.
• LNG-price volatility.
• Longer voyage times.
• Cargo rerouting.
• Vessel shortages.
• Chartering costs.
• Delayed raw materials.
• Petrochemical price increases.
• Supplier force majeure.
• Increased inventory requirements.

The latest oil-market reaction illustrates the commercial sensitivity.

Brent crude ended the week at approximately $92.68 per barrel, rising more than 7% across the week as markets responded to renewed US-Iran hostilities and continuing concerns over Gulf supply.

The significance for businesses is that severe disruption does not require complete interruption.

A sufficiently unreliable route can increase operating costs across the entire supply chain.

Global Impact

Hormuz historically carries a substantial share of the world’s oil and LNG movements.

Reduced navigation therefore has consequences far beyond the Gulf.

Importers are increasingly considering longer and more complex alternative routes, while some Gulf cargoes have already required extraordinary logistics arrangements including ship-to-ship transfers.

Jordan’s Aqaba port has also experienced substantially increased transit volumes as cargo traditionally routed through Gulf ports is redirected towards overland routes into Iraq.

These alternatives can preserve physical trade.

But they introduce additional:

• Road mileage.
• Border crossings.
• Handling.
• Storage.
• Insurance exposure.
• Contractual interfaces.
• Cost.

The logistics system is therefore adapting.

It is not normalising.

Our View

Businesses should now plan for sustained Hormuz disruption rather than assuming rapid restoration of conventional shipping patterns.

Risk managers should ask:

• Which cargoes depend upon Hormuz?
• Which suppliers use Gulf ports?
• Has the carrier reconfirmed the voyage?
• Is the nominated vessel still willing to transit?
• Does the ship appear on any Iranian restriction list?
• Could the cargo route through Aqaba or another regional port?
• What additional inland transport would be required?
• Who pays for rerouting?
• Does the contract permit alternative ports?
• Would a longer voyage breach delivery obligations?
• Does marine cargo insurance remain effective?
• Are war-risk premiums fixed or variable?
• Are additional premiums recoverable contractually?
• Does force majeure apply to restricted navigation?
• Is additional inventory required to absorb longer lead times?
• Are critical energy or petrochemical inputs concentrated in the Gulf?

The key distinction remains:

Hormuz is open in a technical sense but severely impaired in a commercial sense.

Businesses should manage the risk accordingly.
