Executive Summary
The security situation in the Strait of Hormuz has deteriorated again after two supertankers carrying Saudi Arabian crude oil were struck by unknown projectiles within minutes of one another while transiting outbound through the waterway.
The Saudi-flagged VLCC Sidr and Liberian-flagged Senegal Prosperity had each loaded approximately two million barrels of Saudi crude at the Juaymah terminal before attempting to leave the Strait.
Sidr was struck approximately 16.6 nautical miles northeast of Khasab, Oman.
Minutes later, Senegal Prosperity was struck approximately 17 nautical miles east of Khasab.
The situation aboard Senegal Prosperity subsequently deteriorated. The vessel was reported dead in the water and listing to port after being struck three times, including around its port side, engine room and ballast tank.
Its crew was evacuated by local authorities, leaving the vessel abandoned at anchor off the Omani coast. No crew casualties were reported.
Responsibility for the attacks has not been established in the verified reporting.
Meanwhile, US forces carried out further strikes against Iranian military targets bordering the Strait on 1 September. US Central Command said targets included IRGC air-defence sites, radar systems, maritime assets, mine-laying capabilities, communications sites and other facilities, describing the action as a response to recent attempted attacks against commercial shipping and US personnel.
The development changes the commercial calculation again.
Yesterday’s question was whether commercial traffic could safely resume.
Today’s is more serious:
Can vessels carrying strategically important Gulf energy move through Hormuz without becoming direct casualties of the conflict?
UK Impact
UK companies do not need to buy crude directly from Saudi Arabia to be exposed.
Potential consequences extend through:
- Marine insurance.
- War-risk insurance.
- Freight rates.
- Fuel prices.
- Aviation.
- Road transport.
- Chemicals.
- Plastics.
- Manufacturing.
- Electricity.
- Inflation.
The insurance consequence deserves particular attention.
A ship may technically be permitted to transit Hormuz while the economics of doing so become unacceptable because:
- War-risk premiums increase.
- Underwriters restrict cover.
- Shipowners refuse voyages.
- Crews decline assignments.
- Charterers demand different terms.
- Lenders or cargo interests impose additional requirements.
Physical availability of the waterway therefore does not automatically mean commercial availability.
Global Impact
Before the conflict, Hormuz carried approximately one-fifth of global oil supplies.
The significance of the latest tanker incidents is therefore not merely the potential loss associated with two individual ships and their cargoes.
It is the behavioural response of the vessels that have not yet sailed.
A small number of attacks can affect a much larger volume of trade if shipowners, insurers and charterers conclude that the risk has crossed their acceptable threshold.
The abandonment of Senegal Prosperity makes that point particularly stark.
A laden VLCC carrying approximately two million barrels of crude becoming disabled and abandoned inside one of the world’s most important energy corridors demonstrates how quickly geopolitical risk can become:
marine casualty + cargo risk + environmental exposure + salvage problem + navigational hazard + insurance loss.
The latest US strikes against Iranian military capabilities around the Strait also mean the maritime and military risk environments are increasingly intertwined.
Our View
Businesses should no longer model Hormuz simply as:
open or closed.
A more realistic model now includes:
Open
Restricted
Open but commercially unattractive
Escorted
Temporarily suspended
Reopened
Disrupted again
Businesses should ask:
- Which cargoes depend upon Hormuz?
- Who controls the decision to sail: owner, charterer, cargo owner or insurer?
- Has war-risk cover been reconfirmed after the latest attacks?
- Can premium increases be passed through contractually?
- Is alternative routing physically possible?
- What additional transit time would rerouting create?
- Which suppliers have inventory outside the Gulf?
- Which contracts assume unrestricted navigation?
- Could counterparties invoke force majeure?
- Does marine cover respond differently to missiles, drones, mines or unidentified projectiles?
- Who bears salvage and delay costs if a vessel becomes disabled?
- Could an abandoned laden vessel itself obstruct navigation?
- Are customers expecting delivery dates that are no longer realistic?
The critical risk is becoming increasingly clear:
The Strait does not need to be formally closed to become commercially unusable.
If enough vessels, insurers and charterers judge the passage unsafe, market behaviour can achieve much of the same result.
