This course covers Card Usage & Spend Behavior Assumptions, which involves defining and validating assumptions about how customers will use credit cards, including spending patterns, repayment behaviour, cash usage, and revolving tendencies within Credit Card Credit portfolios, within Credit Card Credit. It applies to accounts requiring structured assessment, clear boundary definition, and independent review before any credit action is finalized.
It evaluates key dimensions such as understanding the scope and intent of usage and spend behaviour modelling within credit card products, governance of behavioural assumptions used in underwriting and portfolio design, performance oversight through observed vs expected spend patterns, and ensuring assumptions accurately reflect affordability, credit utilisation tendencies, and lifecycle usage behaviour, with each requiring independent validation and documented rationale to ensure that product design and credit decisions remain aligned with actual borrower behaviour and portfolio risk expectations.
It is distinct from portfolio diversification strategy, as it focuses on structured modelling of customer usage behaviour and spend dynamics for credit card underwriting and product design, rather than broader strategic allocation or diversification considerations—each governed by separate evidence standards, ownership, and approval authority.
Within Credit Card Proposition Design, the credit analyst executes the assessment, completes documentation, and flags exceptions for manager review within Credit Card Credit files, directly influencing escalation scope and credit committee prioritization.
