Contingent Business Interruption Cover for Indian Corporates 2026: Supplier Failures, Tier-1 Dependencies, and Policy Triggers

Contingent Business Interruption (CBI) cover responds to revenue loss caused by physical damage or other defined peril at a location other than the insured's own premises. The cover bridges the gap that standard Business Interruption (BI) cover leaves: standard BI responds only to revenue loss arising from physical damage at the insured's premises. CBI extends the response to revenue loss arising from physical damage at suppliers, customers, utility providers, leader properties, or other defined contingent locations.

Indian corporate CBI placement was historically limited. The 2010 to 2019 placement pattern showed CBI mostly as a small extension to property and BI cover, with sub-limits in the INR 5 crore to INR 25 crore range and limited focus on the underlying supply chain risk. The 2020 to 2023 period changed the placement dynamic. The COVID-19 supply chain disruption, the semiconductor shortage of 2021 to 2023, the Suez Canal blockage of 2021, the Russia-Ukraine conflict from 2022 with consequent commodity disruption, the Red Sea shipping disruption from late 2023, and several India-specific events including the 2023 Sikkim flood disruption to pharmaceutical and electronics supply chains have all combined to surface CBI as a material exposure.

The 2024 to 2026 Indian CBI placement pattern shows three shifts. Limit expansion: typical CBI sub-limits have moved from INR 5 to 25 crore range to INR 50 crore to INR 500 crore depending on the corporate's supply chain concentration. Named supplier specification: placements increasingly include named supplier extensions for the corporate's tier-1 dependencies, providing broader cover for documented supplier failures rather than the narrow unnamed supplier cover. Wording negotiation: buyers are negotiating wording features including indemnity period extension, distance limitation removal, and trigger expansion beyond physical damage to include broader supply chain disruption.

The sectors driving the placement shift are automotive, pharmaceuticals, electronics manufacturing, chemicals, food processing, and increasingly IT services with hardware supply chain dependencies. The buyers are typically mid-cap and large corporates with multi-tier supply chains, single-source dependencies on critical inputs, and revenue concentration that makes supply chain disruption a balance sheet event.

This post walks through the CBI placement framework as it stands in 2026: the named versus unnamed supplier triggers, the automotive and electronics supply chain dependencies that drive Indian placements, the indemnity period nuances, the wording pitfalls that buyers must avoid, the 2025 case studies that demonstrate cover scope, and the INR premium and capacity considerations.

The central wording question in CBI placement is the trigger structure: whether the cover responds to disruption at specifically named suppliers or to disruption at any supplier meeting defined criteria. The two structures provide materially different cover and pricing.

Unnamed supplier trigger

Unnamed supplier CBI cover responds to physical damage at any supplier (or customer, depending on the wording) of the insured, subject to defined parameters. The typical parameters include physical damage by an insured peril (fire, explosion, machinery breakdown, named natural catastrophe, malicious damage), the disruption causing material interruption to the insured's business, and the supplier being identifiable at the time of loss.

The advantage of unnamed cover is breadth: the insured does not need to pre-identify all dependencies, and the cover responds to disruptions at suppliers the insured may not have flagged in advance. The disadvantage is typically lower limit per event and stricter parameter compliance: insurers offering unnamed cover typically constrain the sub-limit to manage their exposure to unknown supplier concentrations.

Typical unnamed supplier sub-limits in 2026 Indian placements range from INR 50 crore to INR 250 crore with 5 to 25 percent of the total BI limit as a common reference range. The cover is most useful for corporates with diversified supply chains where no single supplier dominates input dependency.

Named supplier trigger

Named supplier CBI cover responds to physical damage at specifically identified suppliers listed in the policy schedule. The schedule identifies each named supplier with location, supply type, and contribution to the insured's revenue or operations.

The advantage of named cover is depth: the insurer underwrites each named supplier with site-specific risk assessment, and the limit per named supplier can be calibrated to the dependency. Buyers often secure higher per-supplier limits and broader cover for named suppliers than for unnamed cover. The disadvantage is administrative: the insured must identify and document each named supplier, the schedule must be maintained as supply chain composition changes, and dependencies on un-named suppliers may not be covered.

Typical named supplier sub-limits in 2026 Indian placements range from INR 25 crore to INR 500 crore per named supplier, with cover for the largest tier-1 dependencies sometimes reaching INR 1,000 crore or more. The cover is most useful for corporates with concentrated supply chain dependencies including single-source suppliers, sole-source tooling, or specialised components without ready alternatives.

Hybrid placement

Most sophisticated Indian CBI placements in 2026 use a hybrid structure combining named supplier cover for documented tier-1 dependencies with unnamed supplier cover for broader supply chain exposure. The hybrid provides per-supplier depth for the critical dependencies and breadth for the unidentified or smaller exposures.

The hybrid structure typically includes a schedule of named suppliers with individual sub-limits and an unnamed supplier sub-limit covering any non-scheduled supplier. The aggregate CBI cover may be capped at a programme-level sub-limit that constrains total CBI exposure regardless of which suppliers are involved.

Tier dependency analysis

The named supplier specification requires the insured to conduct a structured tier dependency analysis. The analysis identifies tier-1 suppliers (direct suppliers to the insured), tier-2 suppliers (suppliers to the insured's tier-1 suppliers), and where material, tier-3 suppliers. The analysis quantifies each dependency by contribution to the insured's revenue, criticality of the input, availability of alternatives, and switching cost and time.

The 2026 best practice for Indian corporates is to document the tier dependency analysis as part of the supply chain risk register, with annual review and update. The analysis supports both the CBI placement design and the broader supply chain risk management programme including supplier diversification and inventory buffering.

Customer-side CBI

CBI cover can extend to physical damage at the insured's customer locations, responding to revenue loss when a major customer's operations are disrupted. Customer-side CBI is less common than supplier-side but is meaningful for corporates with concentrated customer dependencies including OEM-supplier relationships, large project customers, or single-buyer contracts.

The customer-side cover typically operates with similar named versus unnamed structures and similar limit considerations. The placement requires customer cooperation in some cases for documentation and access to the customer's risk profile, which can be a practical constraint.

The Indian automotive industry illustrates the CBI exposure pattern with specific clarity. The industry's supply chain shows concentrated tier-1 dependencies on a small number of global and Indian suppliers for critical components, with single-source positions on several inputs that make CBI placement a balance sheet question.

Engine management and braking systems

Bosch India (subsidiary of the German Bosch group) is a dominant supplier of engine management systems, fuel injection systems, braking systems, and ADAS components to the Indian automotive industry. Bosch India operates multiple manufacturing facilities including the Bidadi (Karnataka), Naganathapura (Karnataka), Nashik (Maharashtra), Jaipur (Rajasthan), and Chakan (Maharashtra) plants. A physical damage event at any of these plants can disrupt downstream OEM production with material revenue impact.

The 2026 named supplier CBI placements for Indian OEMs (Tata Motors, Mahindra & Mahindra, Maruti Suzuki, Hyundai Motor India, Bajaj Auto, TVS Motor, Ashok Leyland) routinely include Bosch India as a named supplier with individual sub-limits in the INR 100 crore to INR 800 crore range depending on the OEM's dependency.

Braking systems and air systems

Wabco India (now part of ZF Friedrichshafen following the 2020 acquisition) supplies braking systems, air management systems, and electronic control units for commercial vehicles. Wabco India operates plants at Ambattur (Chennai), Jamshedpur, and Mahindra World City (Tamil Nadu). The dependency is particularly concentrated for Indian commercial vehicle OEMs (Tata Motors commercial vehicles, Ashok Leyland, VE Commercial Vehicles).

Driveline and transmission components

Sona Comstar (Sona BLW Precision Forgings) supplies differential gears, starter motors, and electric vehicle traction motors with significant market share in domestic and export markets. The company operates plants at Gurugram, Manesar, Pune, and Chakan with significant supply concentration to global OEMs.

Electronic components and infotainment

Mindarika (Minda Industries group), Visteon India, Continental Automotive India, Denso India, and Delphi-TVS supply electronic components, infotainment systems, and instrument clusters. The dependencies are distributed across these suppliers but each carries concentration risk for specific OEM relationships.

Castings and forgings

Bharat Forge, Sundaram-Clayton, Sanghvi Forge, El Forge, and Endurance Technologies supply forgings and castings for engine components, suspension components, and structural parts. The dependencies are tier-1 for the OEMs and the engine and transmission specialists.

Tyres

MRF, Apollo Tyres, CEAT, JK Tyre, Bridgestone India, Continental India, and Michelin India supply tyres to Indian OEMs and the aftermarket. Tyre concentration risk is lower than other component categories because the supplier base is broader and switching is relatively fast.

Indian OEM CBI placement structure

The 2026 CBI placement structure for major Indian automotive OEMs typically includes named supplier cover for the top 15 to 25 tier-1 suppliers by dependency contribution. Per-supplier sub-limits range from INR 50 crore to INR 800 crore with the largest dependencies (Bosch India, Wabco India, Sona Comstar) at the upper end. The aggregate CBI cover at programme level typically ranges from INR 1,500 crore to INR 5,000 crore depending on the OEM's revenue scale.

The placement also includes unnamed supplier cover with sub-limit typically INR 200 crore to INR 500 crore providing cover for tier-1 suppliers not specifically named and for tier-2 dependencies that may not be visible to the OEM at the time of placement.

Two-wheeler and tractor industry

The two-wheeler industry (Hero MotoCorp, Bajaj Auto, TVS Motor, Royal Enfield, Honda Motorcycle and Scooter India) and the tractor industry (Mahindra & Mahindra, Sonalika International, Escorts Kubota, John Deere India) follow similar CBI placement structures with adjusted limits reflecting smaller average vehicle revenue and different supplier dependency profiles.

Electric vehicle supply chain

The emerging electric vehicle (EV) supply chain in India creates additional CBI exposure focused on battery cell manufacturers (currently dominated by imports from CATL, BYD, LG Energy Solution, Panasonic), battery pack assemblers (domestic players including Exide Industries, Amara Raja, Tata AutoComp), and traction motor suppliers. The EV CBI placement is evolving with the supply chain, with insurers building underwriting capability for the specific risk profile.

Beyond automotive, the semiconductor and chemical feedstock supply chains generate concentrated CBI exposure for several Indian corporate categories.

Semiconductor supply chain

The semiconductor supply chain affecting Indian corporates runs through multiple tiers. Wafer fabrication is concentrated in Taiwan (TSMC), South Korea (Samsung, SK Hynix), Japan, US, and emerging in mainland China. India's domestic semiconductor manufacturing capacity is at early stage with the India Semiconductor Mission (ISM) projects (Tata Electronics fab in Dholera Gujarat, Micron Technology assembly in Sanand Gujarat, Kaynes Technology OSAT, CG Power-Renesas OSAT, Tata Electronics OSAT in Jagiroad Assam) at various stages of construction and commissioning through 2026 to 2028. The dependency on global wafer fabs continues through the medium term.

Assembly, packaging, and testing (OSAT) is more distributed globally but with concentration in Malaysia, Taiwan, mainland China, and Philippines. Indian OSAT capacity is growing under the ISM but remains limited.

The CBI exposure for Indian corporates dependent on semiconductors runs through several pathways. Indian electronics manufacturers (Dixon Technologies, Foxconn India, Wistron India, Pegatron India, Bharat Electronics, Optiemus Infracom) face direct dependency on chip suppliers. Indian automotive OEMs face indirect dependency through tier-1 electronics suppliers. Indian IT hardware OEMs face direct dependency. Indian appliance and consumer electronics manufacturers face direct dependency.

The semiconductor CBI placement is structurally different from automotive CBI because the named suppliers are typically not Indian entities, the wafer fab locations are global, and the underwriting capacity for these named suppliers requires international reinsurance. The 2026 placement practice typically uses unnamed semiconductor supplier cover with elevated sub-limits in the INR 200 crore to INR 1,500 crore range, with named cover for specific Indian-presence semiconductor partners.

Chemical feedstock concentration

The Indian chemicals and pharmaceuticals industries depend on concentrated feedstock supply with several specific exposure points.

Refinery aromatics and olefins: paraxylene, benzene, ethylene, propylene, butadiene supplied from major refinery and petrochemical complexes including Reliance Industries Jamnagar, Indian Oil Corporation Panipat, Bharat Petroleum Kochi, GAIL India Pata, ONGC Petro additions. The dependency is partly internal (within integrated groups) and partly external.

Specialty chemical intermediates: supplied from concentrated production clusters in Gujarat (Vapi, Ankleshwar, Dahej, Vadodara), Andhra Pradesh (Visakhapatnam, Atchutapuram), Telangana (Hyderabad), Maharashtra (Tarapur, Pune-Chakan), Tamil Nadu (Manali, Cuddalore). The cluster-level concentration creates accumulation exposure: a single major fire or chemical incident in a chemicals cluster can disrupt multiple downstream operations simultaneously.

Active Pharmaceutical Ingredient (API) supply: API supply for Indian pharmaceutical formulators historically had significant dependency on Chinese imports for several KSMs (key starting materials) and intermediates. The 2022 to 2026 PLI scheme for bulk drugs has driven domestic API capacity expansion but the import dependency remains material for several therapeutic categories.

Pharmaceutical CBI placement

Indian pharmaceutical companies place CBI cover for API supplier dependencies including named supplier cover for the largest dependencies and unnamed supplier cover for broader API supply. The placement complexity includes geopolitical risk overlap where API supply disruption may arise from policy or trade disruption rather than physical damage, requiring careful wording to ensure CBI responds to the specific cause of disruption.

Chemical industry CBI placement

Indian chemical companies place CBI cover for feedstock supplier dependencies including named refinery and petrochemical complex cover, named specialty intermediate supplier cover, and unnamed supplier cover for the broader dependency network. The cluster-level accumulation exposure is increasingly addressed through specific cluster aggregation analysis and cluster-specific sub-limits.

Utility and infrastructure dependencies

A related contingent exposure is utility and infrastructure dependency: power supply, water supply, natural gas supply, sewerage, and transportation infrastructure. CBI cover for utility dependencies is typically structured as non-damage business interruption extension responding to utility supply failure regardless of underlying cause, or as named utility supplier CBI requiring physical damage at the named utility provider.

The non-damage extension provides broader cover but typically attracts higher pricing and tighter sub-limits. The named utility supplier CBI requires the physical damage trigger which excludes utility failure from non-physical causes like grid instability, demand-side disruption, or contractual disputes.

Beyond the trigger structure, several wording features in CBI cover materially affect what claims pay and at what level. The 2026 buyer should engage with each feature at placement rather than discover the constraints at claim time.

Indemnity period

The indemnity period is the maximum period for which the CBI cover responds to revenue loss from the contingent event. The period runs from the time of the contingent event (or the start of business interruption at the insured's location, depending on wording) to either the restoration of the supplier's capability to deliver or to the expiry of the indemnity period, whichever is earlier.

The standard indemnity period in Indian CBI cover is 12 months. For deep supply chain dependencies where supplier restoration may take longer, extension to 18 months or 24 months is available at additional premium. The 2026 practice for automotive OEMs with concentrated tier-1 dependencies typically includes 18 to 24 month indemnity period reflecting the practical restoration timeline for major supplier rebuilds.

The indemnity period start point is a wording nuance. Some wordings start the period at the contingent event; others at the start of the insured's business interruption. The latter is more favourable to the insured because the cover responds for the full restoration period including any time lag between the contingent event and the insured experiencing the interruption.

Distance limitation

Many CBI wordings include a distance limitation specifying that the cover responds only to contingent events at supplier locations within a defined distance from the insured's premises or within a defined geographic boundary. Common limitations include:

• Within India only
• Within a specified radius (often 500 km or 1,000 km) from the insured's premises
• Within named countries or regions
• Without distance limitation

The distance limitation can produce surprising coverage gaps. A semiconductor supply disruption from a Taiwan or Korea fab event would be excluded under an India-only distance limitation. A specialty chemical supply disruption from a European supplier would be excluded under a regional radius limitation.

The 2026 best practice is to remove distance limitations or to negotiate explicit cover for the supply chain footprint, with the broker mapping the named suppliers against the distance limitation at placement.

Named perils versus all-risk basis

CBI cover can operate on named perils basis (responding only to specifically listed perils like fire, explosion, machinery breakdown, named natural catastrophe) or on all-risk basis (responding to physical damage from any cause except listed exclusions). All-risk basis is materially broader and is the 2026 best practice for sophisticated placements.

The Indian market typically defaults to named perils basis for CBI cover, mirroring the underlying property cover structure. All-risk extension is available at additional premium and increasingly requested by buyers with sophisticated supply chain risk frameworks.

Trigger expansion

Standard CBI requires physical damage at the contingent location as the trigger. The 2026 wording extensions can expand the trigger to include:

• Cyber events at the contingent supplier
• Pandemic and infectious disease at the contingent supplier
• Strike, riot, and civil commotion at the contingent supplier
• Government action affecting the contingent supplier
• Failure of utility supply at the contingent supplier

Each extension is typically subject to specific wording, sub-limits, and additional premium. The 2026 market capacity for these extensions varies: cyber extension is increasingly available; pandemic extension was withdrawn from most placements after 2020 and is selectively returning; political and government action extensions are typically placed through specialist political risk markets rather than as CBI extensions.

Excess and deductible

The CBI deductible structure can be a time excess (number of days of interruption that the insured retains before cover responds), a monetary deductible (rupee amount that the insured retains), or both. Typical 2026 Indian placements include time excess of 24 to 72 hours for supplier dependencies and 3 to 14 days for longer-duration scenarios, with monetary deductibles in the INR 25 lakh to INR 5 crore range depending on the placement scale.

Aggregate limit and single-event limit

The CBI cover typically operates with both single-event limit (maximum payment for any single contingent event) and aggregate limit (maximum total payment in the policy year across all CBI events). The structure constrains the insurer's exposure and shapes the buyer's net cover. The 2026 placement practice includes negotiation of the aggregate-to-single ratio with typical structures providing aggregate at 2x to 3x the single-event limit.

Documentation and proof of loss

The CBI claim process requires documentation linking the contingent event to the insured's business interruption with established causation. The documentation requirements typically include the contingent event evidence (fire report, surveyor report at the supplier location), the supply contract or relationship evidence, the disruption to supply evidence, the insured's resulting business interruption evidence, and the financial impact quantification.

The 2026 best practice is to maintain supplier documentation in a state that supports rapid claim assembly. The pre-positioned documentation includes current supply contracts, recent delivery records, criticality assessments, and alternative supplier mapping. The documentation file accelerates claim response and reduces the friction of proving the CBI claim.

The disruption events of recent years illustrate the cover scope, the wording dispute patterns, and the practical claim management that brokers should plan for. The scenarios below are illustrative, drawn from the publicly known disruption events of 2023 to 2025 and the recurring CBI placement issues they expose. They are not specific client claims and the recovery outcomes depend entirely on each buyer's wording and limits.

Scenario: tier-1 automotive supplier fire

A fire at a tier-1 electronics or component supplier serving multiple Indian OEMs can halt production of a critical part for months while alternative tooling and capacity are arranged. Where an OEM holds named supplier CBI for the affected plant, with a per-supplier sub-limit calibrated to the dependency, the cover can respond to a substantial share of the gross-profit loss for the indemnity period. Where an OEM relies only on a modest unnamed supplier sub-limit, recovery is capped well below the loss. The practical lesson is that the named-versus-unnamed distinction, and the adequacy of the per-supplier sub-limit, are what separate a meaningful recovery from a token one. Both come down to whether the dependency was identified and properly sized at placement.

Scenario: specialty chemical cluster fire

India's chemical and pharmaceutical intermediates are concentrated in clusters such as Dahej, Ankleshwar, and Vapi. A single major fire in such a cluster can disrupt several downstream formulators at once, because they share dependence on the same intermediate. This is the accumulation problem in CBI: one contingent event can trigger multiple simultaneous claims, and an insurer that under-estimated cluster accumulation at placement faces correlated losses and is likely to reprice or restrict cover at the next renewal. Buyers in such clusters should expect underwriters to ask specifically about cluster-level concentration and should map it themselves before going to market.

Scenario: overseas semiconductor or component disruption

A fire or shutdown at a wafer fab or component plant in Taiwan, Korea, Japan, or Southeast Asia can interrupt chip supply to Indian electronics manufacturers and to tier-1 automotive electronics suppliers. Most standard Indian CBI placements respond poorly here for two reasons: the named-supplier schedule rarely lists overseas fabs, and a distance limitation may confine cover to India or a regional radius. The lesson is that buyers with genuine global dependencies need either named cover for the specific overseas supplier or unnamed cover with the distance limitation removed, and they should confirm that international underwriting capacity has been arranged for those nodes.

Scenario: Red Sea shipping disruption (late 2023 onward)

The Red Sea and Suez diversions that began in late 2023 lengthened transit times and spiked freight rates for many Indian exporters and importers. Standard CBI generally does not respond to this kind of event because there is no physical damage at a named supplier or contingent location, only delay and cost. This exposes the gap between CBI (physical-damage trigger) and supply chain or trade disruption insurance (broader, non-physical triggers). Corporates with route-dependency should treat marine cargo, trade disruption insurance, and supply chain insurance as complements to CBI rather than assume CBI will respond.

Scenario: 2023 Sikkim glacial lake outburst flood

The October 2023 South Lhonak glacial lake outburst flood in Sikkim, which damaged the Teesta-III dam and downstream infrastructure, is a reminder that natural-catastrophe disruption can strike suppliers in regions outside a buyer's usual risk focus. CBI can respond where the supplier suffered insured physical damage and the location falls within cover, but only if the dependency and its geography were mapped. The lesson is to extend supplier dependency mapping to natural-catastrophe exposure across all locations in the chain, not only the obvious industrial belts.

Overall claim lessons

Across these scenarios the recurring lessons are consistent. Named supplier cover with adequately sized sub-limits responds far better than thin unnamed cover. All-risk triggers respond to a wider range of events than named-perils triggers. Distance limitations are the single most common cause of a declined CBI claim on a global dependency. Cluster accumulation requires explicit underwriting attention. And complementary covers are needed wherever the disruption has a non-physical cause that the CBI physical-damage trigger does not reach.

The CBI premium and capacity considerations vary by sector, dependency structure, and wording features. The benchmarks below reflect 2026 market practice across the major Indian non-life insurers and the international markets accessed through brokers for larger placements.

Premium ranges

Automotive OEM placements with named tier-1 supplier cover and aggregate CBI cover in the INR 1,500 crore to INR 5,000 crore range typically attract CBI premium in the INR 2 crore to INR 18 crore range, equivalent to approximately 0.08 to 0.40 percent of the aggregate CBI limit. The wide range reflects supplier concentration, the specific named suppliers covered, the indemnity period selection, and the wording feature negotiation.

Pharmaceutical and chemical placements with named API or feedstock supplier cover typically attract CBI premium in the INR 1 crore to INR 8 crore range for aggregate CBI cover of INR 500 crore to INR 2,000 crore.

Electronics manufacturer placements with semiconductor supplier dependencies typically attract CBI premium reflecting the global supplier underwriting complexity, with rates in the 0.15 to 0.55 percent range of aggregate limit.

Food processing and FMCG placements with raw material supplier dependencies typically attract lower CBI premium reflecting more diversified supply chains, with rates in the 0.05 to 0.25 percent range.

Premium adjustment factors

Supplier concentration: more concentrated supply chains attract higher premium per unit of limit.

Geographic spread: global supplier dependencies attract higher premium than India-only dependencies.

Indemnity period: extension from 12 to 18 or 24 months typically increases premium by 15 to 35 percent.

All-risk basis: extension from named perils to all-risk typically increases premium by 10 to 25 percent.

Trigger extension: cyber, pandemic, or non-physical extensions typically carry significant premium loading or are placed in specialist markets.

Distance limitation removal: removing India-only or regional distance limitations typically increases premium by 10 to 30 percent.

Risk improvement at suppliers: documented supplier-side risk improvement programmes (fire safety, BCP, redundancy) can reduce premium by 5 to 15 percent.

Claim history: prior CBI claims within the lookback period (typically 5 years) can produce premium loading of 25 to 100 percent or coverage restriction.

Capacity considerations

Most major Indian general insurers (Tata AIG, ICICI Lombard, HDFC Ergo, Bajaj Allianz, New India Assurance, Oriental Insurance, National Insurance, United India Insurance) can underwrite CBI cover at scale. The capacity for very large placements (aggregate CBI above INR 3,000 crore) typically requires reinsurance support through GIC Re domestic treaty cessions and international reinsurance through GIFT City, direct foreign reinsurer branches, and Lloyd's. The 2026 Lloyd's India direct entry has added capacity for specialty CBI placements.

Named supplier cover for global suppliers (semiconductor fabs, global chemical complexes, international logistics infrastructure) typically requires international underwriting capacity with placement through the broker's international network.

Placement playbook for 2026 Indian buyers

The placement playbook for Indian corporates considering CBI in 2026 includes the following steps.

1. Conduct supply chain dependency analysis. Identify tier-1 dependencies by revenue contribution, criticality, single-source positions, and switching cost. Map suppliers geographically and identify cluster aggregation exposure. The analysis is the foundation for the placement.
2. Define named supplier schedule. Identify the top tier-1 dependencies for named supplier cover with per-supplier sub-limit calibrated to the dependency. The schedule should be reviewed annually with updates reflecting supply chain changes.
3. Calibrate indemnity period and aggregate limit. The indemnity period should reflect realistic supplier restoration timelines, typically 12 months for diversified supply chains and 18 to 24 months for concentrated dependencies. The aggregate limit should reflect the worst-case combined CBI exposure scenario.
4. Negotiate wording features. All-risk basis, distance limitation removal, cyber and non-physical trigger extension where material, time excess calibration, monetary deductible structure, and aggregate-to-single ratio.
5. Engage suppliers in risk improvement. Supplier-side fire safety, BCP, and redundancy investments support better placement terms and reduce the underlying dependency risk. The 2026 best practice includes joint OEM-supplier risk improvement programmes.
6. Coordinate with adjacent covers. CBI works alongside supply chain insurance, trade disruption insurance, marine cargo, and political risk insurance. The covers should be designed as a programme with consistent definitions, complementary triggers, and clear allocation rules.
7. Document for claim readiness. Maintain supplier documentation in a state that supports rapid claim assembly including current supply contracts, recent delivery records, criticality assessments, and alternative supplier mapping.
8. Renewal cycle. Begin renewal 90 to 120 days before expiry. Update the supplier dependency analysis. Review wording features. Engage insurers with risk improvement progress and any material changes.
