Behavioral Credit Scoring denotes Credit Scoring Models for existing clients of a firm (as opposed to new clients) for which the scoring agent has accumulated performance history.
The main additional information available for existing clients is the internal monitoring history. This may consist of
- Repayment behaviour
- Purchasing / utilization information
The development of a behavioural scorecard may follow the same general principles as a Credit Scorecard as a one-period classification problem but given the continuous monitoring other approaches (e.g. Markov Chains) are also possible.
Accounts can be scored monthly or quarterly. This additional information typically allows more accurate prediction of the odds of an existing account becoming delinquent. In turn the more accurate risk profile may enable the firm to improve efficiency:
- Faster approval for new credit
- Pre-approved credit
- Targeted marketing of products
- More accurate risk pricing
