A proposed 10% credit card interest rate cap could fundamentally disrupt banking technology and risk management systems. Legacy bank infrastructure relies on dynamic pricing models that adjust rates based on individual default probabilities. A hard cap would break these intricate algorithms, forcing banks to radically redesign credit assessment approaches. Financial institutions like JPMorgan and Bank of America warn this could dramatically reduce credit availability. The break-even point for credit card operations is estimated around 15% APR, meaning banks would need to aggressively cut costs or introduce alternative fees to maintain profitability. This policy shock would compel banks to reimagine their entire credit technology infrastructure, potentially triggering massive system overhauls and complex legal compliance challenges across millions of existing accounts.
