Strait of Hormuz War Risk Premium
How marine war risk pricing works for Strait of Hormuz voyages — the Additional War Risk Premium (AWRP), the Joint War Committee (JWC) Listed Areas, what drives the rate here, and where to read the live risk band.
Is there a war risk premium for the Strait of Hormuz?
Yes. Since the Hormuz crisis began in late February 2026, war risk underwriters have been quoting Additional War Risk Premiums for Strait of Hormuz and Persian Gulf voyages, priced per transit as a percentage of the insured hull value. There is no fixed tariff: the rate is negotiated case by case and moves with attacks on shipping, naval developments, and official advisories.

The pricing picture
Hormuz carries roughly a fifth of globally traded oil, and unlike piracy-driven zones the exposure here is state-level: attacks and seizures directed at merchant shipping, drone and missile risk to tanker traffic, and mining threats. That is why the 7-day cancellation clause matters so much in this corridor - underwriters can re-quote the entire risk picture within a week, and premiums have repriced repeatedly through the 2026 crisis.
What drives the rate
- Attacks, seizures, and harassment of merchant vessels in the Strait and Persian Gulf approaches.
- Naval escalation, escort operations, and UKMTO / flag state advisories.
- Vessel nexus: flag, ownership, and cargo links that raise a specific ship's profile.
- Insured hull value, vessel type, and time spent inside the listed area.
How the Additional War Risk Premium works
- Percentage of hull value. AWRP is quoted as a percent of the insured hull value for a fixed exposure window — typically 7 days — while the vessel is inside a listed area.
- Negotiated per voyage. There is no tariff. The rate is agreed between the owner's broker and the war risk underwriter for each transit and moves with the threat level.
- 7-day cancellation clause. War risk cover can be cancelled at short notice (commonly 7 days), after which terms and rate are re-quoted for the new risk picture.
- Separate from P&I war and crew. Hull war is distinct from P&I war cover and from crew war-zone entitlements such as bonus pay and doubled compensation.
Frequently asked questions
How much is the Strait of Hormuz war risk premium?
There is no published rate. AWRP for Hormuz is quoted per voyage as a percentage of hull value and is renegotiated as the threat level shifts. In escalation phases of the 2026 crisis, quotes have repriced sharply within days; in calmer stretches they ease. Brokers obtain current terms from war risk underwriters against the live risk picture.
Does every ship pay AWRP to enter the Persian Gulf?
It depends on the vessel's annual war risk policy and the current listed-area status. When an area sits on the JWC Listed Areas bulletin, entering it typically triggers a notification to underwriters and an additional premium. Terms differ by fleet, insured value, and the owner's claims record.
Can war risk cover for Hormuz be cancelled?
Yes. War risk policies carry an automatic cancellation clause, commonly 7 days' notice, that lets underwriters withdraw or re-price cover quickly when conditions deteriorate. Cover is then reinstated on renegotiated terms.
What is an Additional War Risk Premium (AWRP)?
AWRP is the extra charge a war risk underwriter quotes when a vessel enters an elevated-risk area, usually expressed as a percentage of the insured hull value for a fixed exposure window (commonly 7 days). It sits on top of the annual war risk policy and is negotiated per voyage, so it rises and falls with the threat picture rather than following a published tariff.
Who sets war risk premiums for shipping?
Specialist hull war underwriters, largely in the London and other marine insurance markets, guided by the Joint War Committee (JWC) Listed Areas and the broker's risk presentation. War risk cover carries an automatic cancellation clause, typically 7 days' notice, after which terms and rates can be re-quoted as conditions change.
