Executive Summary
Conflicting signals over the Strait of Hormuz are creating a new risk for global businesses: political declarations that the waterway is reopening are running ahead of normal commercial navigation.
Iran and Oman have made substantial progress towards a temporary transit arrangement, but details remain under negotiation and Tehran continues to attach conditions to broader reopening.
Iranian officials have described arrangements under which inbound commercial traffic could use Iranian waters while outbound traffic could use Iranian and Omani waters. Discussions have also covered mine clearance and mechanisms for managing vessel movements.
However, more detailed reporting indicates that the arrangement has not yet been completely finalised, while Oman has expressed hope that a corridor can soon be formally announced.
At the same time, Washington is intensifying pressure on countries and companies maintaining commercial relationships with Iran, warning of possible secondary sanctions.
The United States is urging countries to reduce Iranian business ties as part of a broader effort to increase economic pressure on Tehran.
This creates an increasingly important distinction:
A ship may eventually be physically able to pass through Hormuz while the cargo, payment, insurer, bank or counterparty remains commercially unusable.
UK Impact
UK companies exposed to Gulf trade should therefore avoid treating reopening as a purely maritime issue.
Even if vessel traffic increases, businesses may still encounter:
- Sanctions restrictions.
- Bank payment blocks.
- Correspondent-bank refusals.
- Vessel-screening requirements.
- Increased compliance checks.
- Trade-finance delays.
- Insurance restrictions.
- Counterparty withdrawals.
- Difficulties settling dollar transactions.
This is particularly important for businesses whose supply chains involve Iranian counterparties only indirectly.
A UK company may buy goods from:
- A UAE trader.
- An Indian refiner.
- A Chinese intermediary.
- A Turkish distributor.
Yet still encounter sanctions or compliance exposure if the underlying trade ultimately connects to a prohibited Iranian party, vessel, cargo or transaction.
Global Impact
The evolving situation creates two parallel tests around Hormuz.
One is physical:
Can the vessel sail?
The other is commercial:
Can the voyage legally and financially be supported?
Those questions involve:
- Banks.
- Insurers.
- Shipowners.
- Commodity traders.
- Port operators.
- Trade-finance providers.
- Cargo owners.
The threat of wider secondary sanctions can also cause companies to withdraw voluntarily from Iranian-linked activity even where a particular transaction has not expressly been prohibited.
That phenomenon — over-compliance — can itself become a supply-chain constraint.
A political announcement that Hormuz is “open” therefore does not necessarily answer the question businesses actually need answered:
Can our transaction safely proceed?
Our View
Businesses should now treat any reopening of Hormuz as a four-part test:
- Is the route physically navigable?
- Is the vessel permitted to transit?
- Is the transaction legally compliant?
- Will banks and insurers actually support it?
Companies should ask:
- Who owns the vessel?
- Who owns the cargo?
- Where did the cargo originate?
- Who ultimately receives payment?
- Is any party designated or connected to a designated entity?
- Which bank will settle the transaction?
- Will correspondent banks process it?
- Has the insurer confirmed cover?
- Does the policy contain sanctions exclusions?
- Are ship-to-ship transfers involved?
- Could the transaction become prohibited while the cargo is in transit?
- Is there a contractual right to suspend performance if sanctions change?
The emerging risk is therefore considerably more complicated than open or closed.
Hormuz may move towards physical reopening while simultaneously becoming harder to use commercially.
