President Donald Trump on Wednesday urged U.S. lawmakers to pass legislation to limit credit card rates to 10%, following his social media post this month ordering banks to voluntarily lower their rates.
"I'm asking Congress to cap credit card interest rates at 10% for one year, and this will help millions of Americans save for a home," Trump said from the World Economic Forum in Davos, Switzerland.
"They charge Americans interest rates of 28%, 30%, 31%, 32%," Trump said. "Whatever happened to usury?"
Shares of banks climbed after the comments. The KBW Bank index climbed 2.2% in morning trading. Capital One, which relies on cards for most of its revenue, climbed 1.9%.
Among the options that the Trump administration had for applying pressure to American banks over card rates, the legislative path may be less threatening. A bill was introduced last year from Sen. Josh Hawley of Missouri and Sen. Bernie Sanders of Vermont that would limit card APRs at 10% for five years; the bill has been stalled in Congress.
Analysts including Sanjay Sakhrani of KBW have said its unlikely that a card bill will have enough bipartisan support to become law. Republican lawmakers, including House Speaker Mike Johnson, have expressed caution when it comes to card price controls.
The episode may show the limits of President Trump's ability to cajole the financial industry into voluntarily giving up billions of dollars in revenue to support his election-year affordability push.
After Trump's Jan. 9 Truth Social post on the rate cap, banks said on earnings conference calls that such a limit would have unintended consequences, including that lenders would simply cancel accounts for many card customers, especially those with lower credit scores.
Privately, bankers and their lobbyists told CNBC they hoped to fend off the president's request, since the most legitimate path for its enactment required legislation.
Several large credit card lenders contacted by CNBC on Tuesday said they had made no changes to their interest rates, but they all declined to be identified.
On Wednesday, JPMorgan Chase CEO Jamie Dimon told a Davos audience that the U.S. government should test out the rate cap in just two states, Vermont and Massachusetts.
Doing so would teach "a real lesson" to those in favor of price controls, Dimon said.
"It would be an economic disaster," Dimon said. "In the worst case, you'd have a drastic reduction of the credit card business" for 80% of Americans, he said.
