Most business owners understand business interruption insurance. If a fire or storm damages their building, the policy can help replace lost income and cover ongoing expenses.
But there is a gap. What happens if your business is fine, but someone you depend on isn’t? That is where contingent business interruption insurance, or CBI, comes in.
CBI covers lost income and extra expenses when your operations are disrupted because of damage to someone else’s property. That “someone else” is usually a key supplier, a major customer, or a nearby business that brings customers to you.
A few quick examples make it clear.
- A restaurant relies on one main food distributor. A fire shuts the distributor down, and the restaurant can’t get the ingredients it needs.
- A manufacturer depends on a single supplier for a critical part. A hurricane knocks that supplier offline, and production stops.
- A retail store depends on a nearby hotel or attraction to drive traffic. A storm damages that property, and foot traffic drops off.
And then there is the customer side of the exposure, which is often overlooked.
If one of your client’s major customers suffers a covered loss and can’t operate, they may stop buying. No orders means lost revenue, even though your client’s business is fully operational. That loss of income is exactly what CBI is designed to address.
Think of a wholesale bakery that supplies a grocery chain. If a key store or distribution point is damaged by fire, orders may slow or stop. Or a small manufacturer that sells to a larger company whose plant is shut down after a storm. In both cases, the insured has no damage, but they feel the financial impact quickly.
That said, CBI is not automatic or unlimited. There still has to be physical damage at the other location, and it has to be caused by something the policy covers. If the cause of loss is excluded, coverage may not apply.
Limits are often lower than the main business interruption coverage, and there may be a waiting period before coverage begins. Some policies require key suppliers or customers to be specifically listed, while others provide limited blanket coverage.
This is where problems can show up. If a business depends heavily on one or two suppliers or customers and they are not properly covered, the policy may not respond the way the owner expects.
Who should consider it?
Any business that relies on a small number of suppliers, customers, or nearby traffic drivers. That includes restaurants, contractors, manufacturers, and businesses tied to tourism or high-traffic locations. If your revenue depends on others, even indirectly, this coverage deserves a look.
The benefit is straightforward. It provides a financial cushion when income is interrupted by events outside your control. It can help cover lost revenue, ongoing expenses, and the added cost of adjusting operations or finding alternatives.
But it works best alongside good planning. Backup suppliers, diversified customers, and a clear understanding of dependencies still matter. Insurance supports those efforts, it does not replace them.
A simple question can bring the issue into focus. If a key supplier or a major customer shut down tomorrow because of a fire or storm, how long could your business keep going? If the answer is not very long, contingent business interruption insurance is a conversation worth having.
