Buyer underwriting is one of the core operating mechanisms of trade credit insurance, ensuring that each buyer in a policyholder’s portfolio is assessed, monitored, and assigned an appropriate level of cover based on risk. Understanding how this process works helps clarify how exposure is controlled and why credit limits form such a central part of the product’s structure.

Underwriting in trade credit insurance takes place at two distinct levels. 

• The first level: the insurer’s decision to provide a business, the policyholder, with a policy at all, based on its overall risk profile as a business. 
• The second level: underwriting the individual buyers that the policyholder trades with once the policy is in place.

The insurer communicates the size of the exposure it is willing to absorb for the policyholder by means of a credit limit. 

Nature and role of the credit limit

In trade credit insurance, a credit limit is the maximum amount an insurer will cover for a specific buyer. It is set after a detailed assessment of that buyer’s creditworthiness that involves looking at financial statements, payment behaviour, industry performance, and the broader economic environment. The limit is shared with the policyholder, either in writing or through an online platform, and acts as a binding ceiling on the insurer’s liability.

A policyholder can choose to sell above the approved limit, but any amount beyond it is uninsured. This makes the credit limit a practical tool for managing exposure. It also provides the policyholder’s credit manager with an external, independent view of the buyer’s risk, which can be useful for deciding how much credit to extend to a buyer. 

Credit limits serve several purposes:

• Risk control: this reduces the chance that a single non-payment could cause significant financial strain.
• Enabling trade: with insurance in place, policyholders can extend credit to buyers they might otherwise avoid, supporting growth in new markets or with less-established customers.
• Portfolio balance: Limits encourage diversification by preventing overreliance on individual buyers, which supports more stable, sustainable trading relationships.
• Ongoing adjustment: Insurers review limits periodically and adjust them to reflect changes in the buyer’s financial position or in market conditions. This helps to keep the coverage aligned with current risk as situations change.
• Claims reference: In the event of non-payment, the credit limit defines the insurer’s maximum payout, so if a policyholder wants to recover the full value of its loss, it will know it needs to stay within the limits.
