Contingent Business Interruption (CBI) insurance protects a business from financial losses caused by disruptions to its suppliers, customers, or other third parties. CBI is also known as Dependent Business Interruption Insurance.
CBI can be an extension of a business’s property insurance policy. It can help protect against Loss of net income, Continuing expenses, and Extra expenses resulting from a key supplier or customer shutdown.
CBI can be used to protect against cyber failures or attacks that interrupt a business’s computer systems and service providers.
CBI has some limitations, including:
To get the most out of CBI, businesses can discuss and agree on claims handling protocols and communication channels at the outset of the policy.

Contingent Business Interruption (CBI) Insurance is a specialised form of business interruption (BI) that protects a business from income loss caused by disruptions in a third party’s operations. Unlike standard BI insurance, which covers losses from direct damage to the insured’s property, CBI coverage extends to losses caused by events affecting key suppliers, customers, or other dependent business relationships.
CBI is triggered when a supplier, customer, or other dependent business suffers physical damage to their property due to a peril (like fire, flood, or natural disaster) that would be covered if it happened at the insured’s own premises. For example, if a key supplier’s factory is damaged by fire, causing a halt in the supply chain, CBI would cover the insured’s loss of income resulting from this supply chain disruption.
CBI insurance typically covers physical loss or damage caused by specified perils, similar to those in the insured’s property policy (e.g., fire, flood, windstorm). Some policies may cover broader risks like pandemics, but this is less common.
Unless explicitly included in the policy, common exclusions include pandemics, cyber incidents, and government-mandated shutdowns.
