About This Paper

Capital One’s acquisition of Discover brings together one of the nation’s largest credit card portfolios with a major payment network. As integration progresses, Capital One may have an opportunity to migrate a significant portion of its credit card portfolio from the Mastercard and Visa networks to the Discover network it now owns and operates.

This paper looks beyond the payments industry to consider how a large-scale portfolio conversion could ripple through the broader consumer lending ecosystem—including credit reporting, credit scoring, lending decisions, consumer spending behavior, and portfolio economics.

What the Paper Explores

• Why Capital One may have economic and strategic reasons to accelerate a network migration
• How a large-scale conversion could create downstream effects in credit reporting and credit scoring
• How even a relatively small number of account discrepancies could affect lending decisions further along the ecosystem
• Potential implications for auto lending, mortgages, personal loans, credit cards, private-label credit, and other consumer financing
• Areas lenders and other industry participants may want to monitor and prepare for as integration progresses

Who It's For

Designed for executives and professionals across consumer lending, credit risk, strategy, operations, credit reporting, scoring, and related areas who want to consider the potential downstream implications of the Capital One–Discover integration.
