How Decision Optimization Improves Credit Line Management
Action-effect models and prescriptive analytics make credit limit increase optimization a powerful tool to improve portfolio performance

Credit line management is regarded as a key driver to profitable portfolios. But despite this, many issuers fail to apply advanced prescriptive analytics to a crucially important process, or if they have, it may often be without a framework or infrastructure to maximise the effectiveness of the insights it can bring. Credit limit increase optimization is a powerful tool to achieve portfolio goals.
Among the underlying elements to optimizing credit limits is a need to have a detailed understanding of the impacts of any actions the issuer takes on their customers. Understanding the action-effect relationship is crucial to creating a solution that enables you to assess the likely impact of multiple alternative scenarios on key performance metrics, including balances and bad debt.
It enables decision-makers to define the best strategy easily and quickly for their credit line management campaign, while supporting critical business objectives. It’s achieved by configuring a decision impact model, which includes and can leverage action-effect modelling.
Action-effect models are analytics that accurately predict how a customer will react to any offer brings great flexibility, but also drive vital insight into potential difficulties in managing the many dimensions of customer behaviour.
Among the crucial elements to understanding the art of the possible and potential value of credit limit increase optimization is the so-called ‘efficient frontier’, which enables issuers to compare differing scenarios and opt for the one that meets their growth objectives and market conditions at the time, while maximising profitability.
Managing Profitability and Exposure
Credit line management optimization helps you manage more than just profit. Overall exposure can also be managed by balancing income and exposure, with risk level typically used as a constraint. The critical value is knowing how, where, and when accepting a slightly higher level of losses will drive an overall increase in the average profit per account — and crucially by how much.

At the same time, CLI campaigns need to ensure they are compliant and don’t offer customers unrealistic or unacceptable limit increases. Constraints can be applied to ensure that strategies are compliant and that they are treating customers fairly.
