Hormuz War Risk Premium — What UAE Vessel Owners Should Expect

Why the Strait of Hormuz Triggers a Separate War Risk Premium

Standard hull cover placed on Institute Hull Clauses (IHC) or Institute Time Clauses — Hulls (ITC-H) excludes war, strikes, terrorism, and related perils by default. The same exclusion applies to cargo cover under Institute Cargo Clauses (A), (B), or (C). The exclusion is not a technicality — it is a hard carve-out that means a mine strike, a missile hit, or a seizure by a state or non-state actor will not be paid under your main hull or cargo policy regardless of how comprehensive that policy appears.

War risk cover is placed separately, typically under the Institute War and Strikes Clauses (Hulls — Time) or the equivalent cargo war endorsements. For vessels trading in or through the Strait of Hormuz, underwriters apply an additional premium — commonly called an Additional War Premium (AWP) or Breach Premium — on top of the base war risk rate. This additional charge is triggered automatically when your vessel enters a JWC-designated area and is calculated on the vessel's insured value for the duration of the transit or stay.

The JWC reviews its listed areas periodically and can add or expand zones with limited notice. When the list changes, your war risk underwriter may invoke a held-covered clause requiring you to notify them before entry and agree a revised premium. If you enter without notification, you risk voiding the war risk element of your cover entirely. Your broker should have a standing notification protocol in place so that voyage orders trigger an automatic advisory to the war risk underwriter before the vessel crosses the boundary.

What Your War Risk Policy Covers — and Where the Gaps Are

A properly structured war risk placement for Hormuz trading should respond to physical loss or damage caused by war, civil war, revolution, hostile acts by or against a belligerent power, mines, torpedoes, bombs, and terrorism. For hull, the Institute War and Strikes Clauses also cover piracy — a relevant peril given the historical activity in the Gulf of Oman and the ongoing situation in the Red Sea approaches.

Detention, seizure, and confiscation by a government authority present a more nuanced picture. Some war risk policies include a detainment clause that responds after a defined period of detention with no news; others exclude government seizure entirely or require a separate political risk endorsement. If your vessel operates on charter in the Gulf and could be detained by port state control or a coastal authority during a period of heightened tension, you need to confirm with your broker exactly how your policy responds — and whether the detention trigger period aligns with your commercial exposure.

Crew war risk is a separate consideration governed partly by MLC 2006 obligations. Your P&I entry covers crew liability in most circumstances, but war risk to crew — including medical evacuation costs, death and disability arising from a hostile act — may fall outside standard P&I cover in a war zone unless your P&I club has specifically extended cover or you have a standalone crew war risk policy. MLC 2006 requires shipowners to maintain financial security for crew repatriation and compensation; a gap in war zone crew cover can expose you to both a regulatory breach and an uninsured liability.

• Typically covered: physical damage from hostile acts, mines, piracy, terrorism, general average arising from a war peril
• Typically covered: constructive total loss following capture or seizure (subject to detainment clause timelines)
• Typically excluded or sub-limited: cyber-enabled attacks unless a specific cyber war endorsement is added
• Typically excluded: loss of hire or delay caused by war risk events unless a separate loss-of-hire war extension is placed
• Typically excluded: cargo carried under a bill of lading where the shipper has not declared war risk cover separately
• Check carefully: confiscation by UAE, Omani, or Iranian authorities may be excluded as government seizure rather than war peril

Cargo Owners and Freight Forwarders: Your Exposure Is Not the Same as the Shipowner's

If you are a cargo owner or freight forwarder moving goods through Jebel Ali, Khor Fakkan, or transhipping via a feeder service into the Gulf, your war risk exposure sits in a different policy layer from the vessel owner's hull cover. The carrier's hull war risk policy does not protect your cargo. Under Hague-Visby Rules — which govern most bills of lading issued in UAE ports — the carrier's liability for war-related loss is limited and in many cases excluded entirely. You need your own cargo war risk endorsement attached to your Institute Cargo Clauses (A) placement.

The cargo war risk endorsement should be checked against the specific routing. A policy that covers Hormuz transit may not automatically extend to Bab-el-Mandeb or Red Sea transshipment legs, both of which are currently JWC-listed. If your supply chain involves a multi-leg voyage — say, a feeder from Jebel Ali to a mother vessel calling Salalah before transiting the Red Sea — each leg needs to be within the geographic scope of your war risk endorsement. Ask your broker to map the routing against the policy wording before the goods are loaded.

General average is another exposure cargo owners underestimate. If a vessel suffers a war-related incident and the master declares general average under York-Antwerp Rules, cargo interests will be required to contribute to the shared loss before their goods are released. Without a cargo war risk policy that responds to general average contributions, you may face a cash deposit or guarantee demand at destination that delays your supply chain and creates an uninsured cost.

How the Hormuz War Risk Premium Is Structured at Renewal

For hull, the base annual war risk premium is set at policy inception and reflects the vessel's trading area, flag, age, and insured value. The Hormuz AWP is then charged on top for each voyage into or through the listed area, calculated as a rate applied to the hull insured value for the number of days in the zone. The rate is not fixed — it is market-driven and can move significantly when incidents occur in the region. Underwriters reserve the right to revise the AWP rate on short notice, typically seven days, which means a voyage that was economical to insure when you fixed the charter may cost more by the time the vessel sails.

At renewal, your broker should be presenting underwriters with a full trading history for the prior period, including the number of Hormuz transits, any incidents or near-misses, and the vessel's current trading pattern. Underwriters will also want to know whether the vessel has traded into Iranian waters or called at sanctioned ports — both of which can affect the availability of cover and the terms on which it is offered. Sanctions compliance is not just a legal obligation; it is a coverage condition. A breach of OFAC, EU, or UK sanctions can void your war risk policy entirely.

Capacity for Hormuz war risk is concentrated in the London market and a small number of specialist company market underwriters with Gulf expertise. Singapore market underwriters through MAS-regulated carriers are an alternative for vessels managed out of the region, and DIFC and ADGM-based insurers are increasingly active for UAE-domiciled risks. Your broker should be accessing multiple markets to ensure you are not dependent on a single underwriter's appetite, particularly given how quickly that appetite can change when the threat level rises.

What to Bring Your Broker Before Placing or Renewing Hormuz War Risk Cover

The quality of information you provide directly affects both the terms you receive and the speed at which cover can be bound. Underwriters placing war risk on Gulf-trading vessels are making a real-time risk assessment; incomplete submissions result in either declined quotes or heavily qualified terms that may not respond when you need them to.

For hull war risk, your broker will need the vessel's class certificate, trading area declaration, flag state, insured hull and machinery value, and a summary of the prior year's trading including Hormuz transit frequency. If the vessel has had any incidents — even those not resulting in a claim — disclose them. Non-disclosure of a material fact is grounds for avoidance of the policy under UAE insurance law and under the Marine Insurance Act principles that underpin most London market placements.

For cargo war risk, bring your bill of lading terms, the routing for each shipment or the annual declaration of cargo movements if you are placing an open cover, the commodity type and packing, and the declared cargo value. If you are a freight forwarder placing cover on behalf of multiple shippers, confirm that your open cover wording permits you to declare third-party cargo and that the war risk extension is not limited to named vessels or named ports.

• Vessel particulars: IMO number, flag, class society, year of build, GRT/DWT
• Trading declaration: ports of call, frequency of Hormuz transits, any Red Sea or Bab-el-Mandeb routing
• Insured values: hull and machinery, increased value if applicable
• Prior claims history: last three to five years, including war risk and P&I
• Charter party terms: any war risk clauses imposed by charterers or cargo interests
• Sanctions compliance confirmation: no calls at OFAC, EU, or UK-designated ports in the prior period
• Crew details for crew war risk: nationalities, MLC 2006 financial security certificates

P&I and War Risk: Understanding the Boundary

Your P&I entry with an International Group club covers third-party liabilities — collision, pollution, cargo damage claims, crew injury — but most P&I clubs exclude war risks from their standard rules. When a vessel is in a JWC-listed area, the club may invoke a war exclusion that limits or removes cover for liabilities arising from a war peril. Some clubs offer a war risk P&I extension or a separate war risk P&I policy; others do not, leaving a gap that must be filled in the commercial market.

The LLMC (Convention on Limitation of Liability for Maritime Claims) sets the framework within which shipowners can limit their liability for most maritime claims, including those arising from collision or pollution. However, limitation is not available for all claim types, and in a war risk scenario involving state actors or terrorism, the legal landscape becomes more complex. Your broker should be reviewing whether your P&I war risk extension, if you have one, aligns with your LLMC tonnage-based limitation figures and whether there are scenarios — particularly involving third-party property damage from a war peril — where your liability could exceed both the limitation figure and the policy limit.

For charter operators, the charter party will typically include a CONWARTIME or VOYWAR clause that defines the parties' rights and obligations when the vessel enters a war zone. These clauses can require the charterer to pay the war risk premium, give the owner the right to deviate or refuse to enter a listed area, and allocate general average contributions. Understanding how your charter party war clauses interact with your insurance cover is not a legal nicety — it determines who bears the cost when the AWP spikes mid-voyage.

Frequently asked questions

Do I need a separate war risk policy if my hull cover already includes the Inchmaree clause?

Yes. The Inchmaree clause extends your hull policy to cover certain accidental damage caused by crew negligence, latent defects, and similar perils — it does not cover war, mine, or terrorism losses. Those perils are excluded from standard hull cover regardless of what extensions are in place. War risk must be placed separately under the Institute War and Strikes Clauses or an equivalent wording.

What happens if the JWC expands the listed area while my vessel is already in the Gulf?

Your war risk policy should contain a held-covered provision that allows you to remain covered when a new area is listed, subject to prompt notification to the underwriter and agreement of a revised premium. If you do not notify, you may be trading uninsured for war perils. Your broker should have a standing instruction to alert you immediately when JWC listings change so you can notify the underwriter before the held-covered window closes.

How long does it take to bind Hormuz war risk cover?

For a straightforward vessel with a clean trading history and complete submission, a war risk quote can typically be bound within one to two working days. If the vessel has a complex trading pattern, prior incidents, or requires a crew war risk extension, allow more time. Do not wait until the vessel is at anchorage outside the Strait — by then your negotiating position is weak and some underwriters will decline to quote under time pressure.

What do you need from me to get a quote?

At minimum: IMO number, flag, class certificate, insured hull value, trading area declaration including Hormuz transit frequency, and three to five years of claims history. For cargo, we need the bill of lading terms, routing, commodity, and declared values. If you are placing crew war risk, we need nationalities and your MLC 2006 financial security documentation. The more complete your submission, the better the terms we can negotiate on your behalf.

Does my cargo war risk cover apply if the goods are transhipped at Khor Fakkan onto a different vessel?

It depends on your policy wording. Many cargo war risk endorsements cover the goods on a warehouse-to-warehouse basis through the named routing, but transhipment onto an unnamed vessel can create a gap if the policy requires declaration of the carrying vessel. If your supply chain involves transhipment — which is common for feeder services out of UAE ports — ask your broker to confirm that the open cover or endorsement wording covers all legs and all carrying vessels, not just the named ocean vessel.

Can my charter party force me to enter a JWC-listed area even if my insurer has not confirmed cover?

CONWARTIME and VOYWAR clauses in standard charter parties give the owner the right to refuse entry into a war zone or to require the charterer to pay any additional war risk premium. However, the contractual right to refuse and the insurance position are separate issues. If you enter a listed area without confirmed war risk cover — even under charterer pressure — you are trading uninsured for those perils. Always confirm your insurance position before the vessel sails, and ensure your charter party war clauses are reviewed by your broker alongside your policy wording.
