Shares in major U.S. lenders plummeted Monday morning after President Donald Trump blindsided the financial sector with a proposed 10% ceiling on credit card interest rates.
The surprise announcement, issued late Friday via Truth Social, has sent shockwaves through a banking industry that had previously anticipated a period of historic deregulation.
Lenders with heavy concentrations in consumer finance bore the brunt of the selloff.
Capital One Financial Corp. and Synchrony Financial—which focus almost exclusively on credit card lending—saw their shares slide as much as 11% in premarket trading.
Industry titans American Express and Citigroup dropped 4.8% and 4% respectively, while JPMorgan Chase and Bank of America also traded lower as investors weighed the threat to net interest income.
"Effective January 20, 2026, I, as President of the United States, am calling for a one year cap on Credit Card Interest Rates of 10%," Trump wrote, setting a deadline that coincides with the first anniversary of his second term.
He doubled down on the proposal Sunday while aboard Air Force One, telling reporters that lenders who do not comply would be "in violation of the law."
