Credit limit management for BNPL / Consumer lending

Published on: 2024-08-10 18:37:05

There are two main points when a credit limit should be evaluated for a customer in BNPL or consumer lending. The first is new loan underwriting. The second is during the upsell and cross-sell stage. Another important part, which is often missed, is credit limit re-evaluation based on behavioral signals during portfolio monitoring.

In new loan underwriting, you need to assess the credit risk of a potential customer and set the credit limit using historical data such as payment records and borrowing behavior. For example, if a customer has paid on time and used credit responsibly, she is likely to qualify for a higher credit limit.

When the customer already has an account, you need to assess whether she is likely to default. If not, you can offer a higher credit limit. If the risk has increased, you should be careful about raising it.

There are several factors to consider when setting or adjusting a credit limit:

  1. The customer's credit score
  2. The customer's credit history
  3. The customer's income and employment stability
  4. The customer's current debts
  5. The customer's spending habits
  6. The customer's other assets
  7. The customer's age
  8. The customer's history with the company
  9. The customer's repayment history
  10. The customer's overall financial health

Traditionally, companies choose to change credit limits only upward. But in some cases, it is necessary to lower a customer's credit limit. Reasons to lower a credit limit may include:

  1. The customer has missed payments or paid late
  2. The customer has maxed out the credit limit
  3. The customer has a high debt-to-income ratio
  4. The customer has been approved for a new loan with a higher interest rate
  5. The customer has applied for a new credit card
  6. The customer has lost their job
  7. The customer has filed for bankruptcy
  8. The customer has a lower credit score than when the limit was first approved

The process of evaluating and adjusting credit limits should be handled carefully, especially in a weaker macroeconomic environment. A practical approach is to run portfolio reviews weekly using internal data, and monthly with support from credit bureau checks.

A practical setup is to define a standard limit calculation and reuse the same decision logic across credit underwriting, cross-selling, and portfolio limit monitoring.
