Marine Cargo Insurance and War Risk Premiums: AI Documentation for Maritime Claims in 2026
Aditya GuptaMarch 13, 202611 min readWar risk premiums for marine cargo insurance have surged to levels not seen since the Gulf War era, and marine surveyors are dealing with an unprecedented volume of complex claims on conflict-affected shipping routes. As someone who has worked closely with marine insurance professionals across India and the United States, I can tell you that the combination of Red Sea disruptions, Black Sea conflict, and Persian Gulf tensions has created a documentation challenge that traditional survey methods simply cannot handle. This article covers how war risk premiums work, what marine surveyors need to document for war-risk claims, and how AI tools like FieldScribe AI are helping professionals process these complex cases efficiently.
Why Have Marine War Risk Premiums Increased So Dramatically?
Marine war risk insurance is a separate coverage from standard marine cargo policies. The standard Institute Cargo Clauses (A, B, or C) explicitly exclude loss or damage caused by war, civil war, revolution, rebellion, insurrection, or hostile acts by or against a belligerent power. To cover these excluded perils, shippers and cargo owners purchase separate war risk policies under the Institute War Clauses (Cargo).
The pricing of these war risk policies depends heavily on the specific shipping route. The Joint War Committee (JWC) at Lloyd's of London maintains a list of areas where additional premiums are required. As of early 2026, the JWC Listed Areas include the Black Sea and Sea of Azov, the Red Sea and Gulf of Aden (including the Bab el-Mandeb strait), parts of the Persian Gulf, waters around the Horn of Africa, and several other regions. Ships transiting these areas face additional war risk premiums that can add 0.5% to 2% of cargo value per transit, compared to the pre-2022 rates that were often below 0.05%.
For Indian trade, this is particularly significant. India imports roughly 85% of its crude oil, much of it through the Strait of Hormuz. Container traffic between India and Europe transits either the Suez Canal (through the Red Sea) or takes the longer route around the Cape of Good Hope, adding 10-14 days and corresponding costs. Indian shipping companies and cargo owners are paying war risk premiums that are 10 to 20 times higher than three years ago on certain routes. For our comprehensive guide on marine insurance documentation, see the marine insurance survey report guide.
US trade is similarly affected, though the routes differ. US imports from Asia through the Suez Canal, US military supply shipments through the Persian Gulf, and US agricultural exports (especially grain) through the Black Sea all face elevated war risk costs. The US marine insurance market, centered in New York with significant Lloyd's participation, has seen war risk premium pools grow from approximately $800 million in 2021 to over $3 billion in 2025.
What Do Marine Surveyors Need to Document for War-Risk Claims?
War-risk marine claims are more complex than standard cargo damage claims. The surveyor must document not just the physical damage but also the circumstances that caused it and the connection to a war-related peril. Here is what a thorough war-risk survey report needs to include.
Voyage details and route verification. Document the vessel's planned route, actual route, and any deviations. If the vessel deviated to avoid a JWC Listed Area and the deviation caused delay damage (such as spoilage of perishable cargo), the route documentation becomes central to the claim. Obtain copies of the vessel's Automatic Identification System (AIS) data, which provides a GPS track of the ship's actual movements.
Incident description with official sources. If the cargo was damaged by a missile strike, drone attack, mine, or other hostile act, document the incident using official sources: flag state investigation reports, port authority incident reports, and any available military communications. The surveyor's report should reference these sources rather than relying solely on the master's statement, which may be self-serving.
Physical damage assessment. This is where standard marine survey skills apply. Document the condition of the cargo, containers, packaging, and vessel structure at the affected areas. Use geotagged photographs with timestamps. For containerized cargo, document the container number, seal condition (intact, broken, or replaced), and any external damage before opening. Once opened, photograph the interior condition and individual damaged items or cargo lots.
Salvage and mitigation documentation. War-risk claims often involve emergency salvage operations. Document salvage efforts, temporary storage arrangements, and any mitigation measures taken to prevent further loss. The General Average provisions of the York-Antwerp Rules may apply if the vessel sacrificed cargo or incurred extraordinary expenses to save the maritime adventure. Your documentation of these events directly affects the General Average adjustment.

How Do War Risk Claims Differ Between Indian and US Markets?
The regulatory and market structures for marine war risk insurance differ significantly between India and the United States.
India: Marine insurance in India is governed by the Marine Insurance Act 1963, which is based on the UK Marine Insurance Act 1906. The General Insurance Corporation of India (GIC Re) acts as the national reinsurer and provides war risk reinsurance capacity for Indian insurers. IRDAI regulates premium rates and policy terms. Indian marine surveyors must hold an IRDAI surveyor license with the marine category. War risk claims in India follow the standard claims process but with additional documentation requirements related to the war-related peril. The surveyor must submit reports within IRDAI-mandated timelines, which can be challenging when cargo is stranded in a conflict zone or held at a foreign port.
United States: The US marine insurance market operates with less regulatory prescription than India. War risk policies are typically written in the London market (Lloyd's) or by US domestic marine insurers and surplus lines carriers. The Federal Maritime Administration (MARAD) provides war risk insurance for US-flag vessels and their cargo when commercial war risk coverage is unavailable, under Title XII of the Merchant Marine Act 1936. US marine surveyors are not licensed by a single federal authority; qualifications are market-driven, with professional bodies like the National Association of Marine Surveyors (NAMS) providing certification.
The key practical difference for surveyors is documentation format. Indian surveyors must follow IRDAI-mandated report structures. US surveyors have more flexibility in report format but must meet the specific requirements of the underwriter or claims adjuster who commissioned the survey. FieldScribe AI accommodates both by providing customizable report templates that can be configured for either market.

What Role Does AI Play in Processing Marine War-Risk Claims?
Marine war-risk claims generate enormous volumes of documentation: vessel logs, AIS data, port authority reports, military incident records, cargo manifests, bills of lading, letters of credit, and the physical damage evidence from the survey itself. Processing all of this manually is slow and error-prone.
FieldScribe AI helps marine surveyors in several specific ways.
Structured evidence capture at port. When you are inspecting damaged cargo at a port, time is expensive. Demurrage charges, container detention fees, and port storage costs accumulate daily. FieldScribe AI lets you capture evidence rapidly using voice notes, geotagged photos, and structured forms, then generates the report after you leave the port. This reduces your time on-site, which directly reduces the insured's ancillary costs.
Multi-language documentation. Marine claims are inherently international. The vessel may be flagged in Panama, crewed by Filipino officers, carrying cargo owned by an Indian importer, insured by a London market underwriter, and surveyed at a Turkish port. FieldScribe AI handles voice recordings in multiple languages and generates reports in English, which is the standard language for international marine insurance documentation.
Cross-referencing cargo documentation. The AI can help organize the relationship between the bill of lading, packing list, commercial invoice, and your physical damage findings. If the packing list says 500 cartons but you count 480 intact and 15 damaged, the AI flags the 5-carton discrepancy for investigation. This is the kind of detail that gets lost in manual reporting but can be significant in a war-risk claim where pilferage during emergency transshipment may have occurred.
Report generation with war-risk specific sections. War-risk survey reports need specific sections that standard cargo survey reports do not: incident narrative, route analysis, war risk policy clause identification, and General Average considerations. FieldScribe AI includes these sections in its marine war-risk report template.

How Are Red Sea Disruptions Affecting Marine Insurance in 2026?
The Houthi attacks on commercial shipping in the Red Sea and Gulf of Aden, which escalated in late 2023, have had a lasting impact on marine insurance markets. As of early 2026, approximately 60-70% of container shipping that previously transited the Suez Canal has been rerouted around the Cape of Good Hope.
For insurers, this means several things. War risk premiums for vessels still transiting the Red Sea remain at elevated levels, typically 0.75% to 1.5% of hull value per transit. Standard marine cargo policies have seen rate increases of 15-25% even for Cape route shipments due to overall market conditions. Delay-related losses, including spoilage, contractual penalties, and increased financing costs, have generated a new category of claims that were rare before 2024.
For Indian importers and exporters, the rerouting has added approximately $800 to $1,200 per TEU (twenty-foot equivalent unit) in freight costs for Europe-India trade. War risk premiums add another $200 to $500 per container depending on the cargo value and the specific route. Indian marine surveyors are handling claims for delayed cargo, temperature-sensitive goods damaged by the extended voyage, and cargo damaged during emergency diversions.
For US shippers, the primary impact has been on eastbound trade to Europe and the Middle East. US agricultural exports, petroleum products, and manufactured goods destined for markets east of Suez face the same rerouting costs. US marine surveyors are seeing increased claims for contamination, shifting, and deterioration related to the longer voyage times.
What Should Marine Surveyors Do When Cargo Is Stranded in a Conflict Zone?
Cargo stranding is one of the most difficult scenarios in marine insurance. When a vessel is trapped in a port or waterway due to conflict, the cargo may be inaccessible for weeks or months. The Suez Canal blockage of 2021 (the Ever Given incident) was a logistics event, not a war event, but it illustrated the documentation challenges. The vessels trapped in the Great Bitter Lakes of the Suez Canal during the 1967 Arab-Israeli war remained stranded for eight years.
When cargo is stranded, the surveyor's role shifts to managing the loss from a distance. Document the vessel's location and condition using available shipping intelligence and AIS data. Correspond with the vessel's master, agent, and P&I club to obtain condition reports. Monitor temperature logs for refrigerated containers. Assess whether the cargo can be transshipped, returned to origin, or must be abandoned. All of this correspondence and analysis should be captured systematically in your documentation tool rather than scattered across emails, WhatsApp messages, and handwritten notes.
FieldScribe AI allows you to create a claim file that includes both field survey evidence (when you eventually gain access) and the remote documentation gathered during the stranding period. This creates a complete claim narrative from initial notification through final settlement.
Frequently Asked Questions
What is the difference between war risk insurance and standard marine cargo insurance?
Standard marine cargo insurance under the Institute Cargo Clauses covers physical loss or damage from maritime perils such as heavy weather, grounding, collision, and fire. War risk insurance under the Institute War Clauses covers loss or damage caused by war, civil war, revolution, insurrection, mines, torpedoes, bombs, and other hostile acts. These are separate policies with separate premiums. Most cargo owners purchase both, but the war risk policy can be cancelled at short notice (typically 7 days) if the risk profile changes dramatically.
How are war risk premiums calculated for specific shipping routes?
War risk premiums are calculated based on the JWC Listed Areas the vessel will transit, the vessel's flag state and classification, the cargo type and value, the duration of transit through the listed area, and the current threat level assessed by military and intelligence sources. Premiums are quoted as a percentage of the insured value, typically ranging from 0.01% for low-risk routes to 2% or more for high-risk transits. Rates can change daily based on incidents and intelligence reports.
Can Indian exporters claim war risk premium increases as a business expense?
Yes. War risk premiums paid by Indian exporters are legitimate business expenses and can be included in export pricing, claimed as deductions for income tax purposes, and factored into letters of credit and trade finance arrangements. The Directorate General of Foreign Trade (DGFT) has acknowledged the impact of increased war risk costs on Indian exports. Some export promotion councils have lobbied for government subsidies to offset war risk premium increases, though no formal scheme has been announced as of early 2026.
What happens to cargo insurance when a vessel changes its route to avoid conflict areas?
Most marine cargo policies include a Change of Voyage clause that maintains coverage if the vessel deviates from the planned route due to circumstances beyond the shipper's control. Route changes to avoid JWC Listed Areas generally fall within this provision. However, the policyholder should notify their insurer of significant route changes as soon as they become aware. The war risk premium may be adjusted if the new route avoids or enters a JWC Listed Area. Extended voyage duration may also trigger additional premium calculations under the standard duration clause.
How do General Average claims work in war-risk situations?
General Average is declared when the master intentionally sacrifices part of the cargo or incurs extraordinary expenses to save the vessel and remaining cargo from a common peril. In war-risk situations, this could include jettisoning cargo to increase speed while fleeing an attack, paying ransom in a piracy situation, or incurring emergency port costs to escape a conflict area. When General Average is declared, all cargo interests contribute proportionally to the loss based on their CIF value. The marine surveyor's documentation of the event, the sacrifice or extraordinary expense, and the condition of the surviving cargo is crucial for the General Average adjustment.
Are there government-backed war risk insurance schemes for essential trade routes?
Yes, several countries maintain government war risk insurance schemes. The US Federal Maritime Administration (MARAD) provides war risk insurance for US-flag vessels under Title XII of the Merchant Marine Act. The UK has the Mutual War Risks Association and government backing through the Department for Transport. India does not have a dedicated government war risk insurance scheme, but GIC Re provides reinsurance capacity for war risk policies written by Indian insurers. Several European nations activated government war risk schemes during the early stages of the Russia-Ukraine conflict when commercial markets temporarily withdrew capacity.
