JPMorgan Chase CEO Jamie Dimon has warned that Donald Trump's proposal to cap credit card interest rates at 10% would be an "economic disaster," potentially cutting credit access for a large portion of Americans.

• Jamie Dimon stated a 10% cap would remove credit from 80% of Americans and negatively impact sectors including restaurants, retailers, and travel firms.
• Donald Trump proposed on Truth Social a one-year cap of 10% on credit card interest rates starting January 20, 2026.
• The average interest rate for credit cards in the US is currently around 20%, and the proposal has already affected investors in firms like American Express, Visa, and Mastercard.
