JPMorgan Chase CEO Jamie Dimon has raised serious concerns about the potential fallout from proposed credit card interest rate caps. According to his assessment, implementing such a policy could trigger a credit crunch across the US financial system. Banks would likely respond by tightening lending standards and withdrawing credit lines from most consumers, rather than absorbing margin compression. The move could have cascading effects on credit availability, borrowing costs for businesses, and overall economic liquidity. This positions the debate around rate controls as a policy trade-off: while aimed at consumer protection, the unintended consequences might actually restrict credit access for the majority of Americans who rely on traditional banking services.
