“Please be informed that we will no longer let the American Public be ‘ripped off’ by Credit Card Companies that are charging Interest Rates of 20 to 30%, and even more, which festered unimpeded during the Sleepy Joe Biden Administration. AFFORDABILITY!” he wrote on social media.

It’s not clear whether credit card companies will respond to his call, or what actions he might take to force any change.

The post comes as the Trump administration intensifies efforts to demonstrate to voters that the president is addressing concerns about costs and prices that have emerged as a central issue in the November midterm elections.

During the 2024 presidential campaign, Trump pledged to seek limits on the interest credit card companies can charge.

Hours before his message on Friday, Senator Bernie Sanders, a Vermont independent, said on X: “Trump promised to cap credit card interest rates at 10% and stop Wall Street from getting away with murder. Instead, he deregulated big banks charging up to 30% interest on credit cards.”

In a letter last year to Sanders and Senator Josh Hawley, a Missouri Republican, a group of banking trade groups painted a dire outcome for consumers if the government ever capped interest rates on credit cards at 10%, as the senators had proposed.

“Many consumers who currently rely on credit cards would be forced to turn elsewhere for short-term financing needs, including pawn shops, auto title lenders or worse — such as loan sharks, unregulated online lenders and the black market,” the group wrote.

The Bank Policy Institute said in a report last year that “while the proposed cap is a well-intentioned effort to reduce the high debt burden some households are facing, it would harm consumers’ access to card credit.” The group also said such a move could force card issuers to reduce cardholder benefits, including lucrative rewards tied to purchases. 

Responding to Trump’s post on Friday, Hawley said on X: “Fantastic idea. Can’t wait to vote for this.”
