Trump’s Credit Card Cap: Why Price Controls Harm Consumers & the Economy

The proposal by President Donald Trump to cap credit card interest rates at 10% has ignited a debate among financial experts, with concerns raised that such a measure, while potentially offering short-term relief to consumers, could ultimately restrict access to credit, particularly for those with lower credit scores. The idea, which has surprisingly garnered some support from Democrats like Senator Elizabeth Warren, aims to prevent what Trump described as consumers being “ripped off” by credit card issuers.

However, leading financial institutions, including JPMorgan Chase, have warned of significant negative consequences. Jeremy Barnum, JPMorgan Chase’s Chief Financial Officer, stated that a 10% cap would lead to a substantial reduction in credit availability, especially for individuals who need it most. This sentiment is echoed by analysts who point to the inherent risks associated with lending to borrowers with less-than-perfect credit histories.

Currently, the average credit card interest rate hovers around 24%, with rates for those with poor credit reaching as high as 36%, according to LendingTree. A 10% cap would dramatically alter this landscape. A Vanderbilt University analysis from September 2025 estimated that such a cap could save consumers approximately $100 billion annually in reduced interest payments. For example, a cardholder with a $5,000 balance would pay around $42 per month in interest at 10%, compared to approximately $100 per month at the current average rate of 24%.

Despite the potential for savings, the core concern revolves around the risk assessment inherent in lending. Banks and financial institutions price interest rates based on the borrower’s creditworthiness and the associated risk of default. A mandated 10% cap would effectively force lenders to absorb a greater portion of that risk, potentially leading them to tighten lending standards or reduce credit lines for higher-risk borrowers. Ted Rossman, a senior industry analyst at Bankrate, explained that these borrowers “would find it dramatically more difficult to access credit.”

This concern is further supported by historical precedents. The imposition of price controls, as demonstrated by President Nixon’s 1971 gasoline price controls, often leads to unintended consequences, namely reduced supply. In that instance, artificially low prices spurred increased demand but simultaneously discouraged production, resulting in shortages and long lines at gas stations. Similarly, rent control policies in cities like New York, San Francisco, and Los Angeles have been criticized for discouraging investment in maintenance and new housing development.

The fundamental issue, as highlighted by the American Action Forum, is that capping rates would necessitate banks finding alternative revenue streams, potentially through increased fees for all credit card users. It could lead to a reduction in rewards programs and other card benefits, including fraud protection. The Cato Institute emphasizes that price controls historically result in shortages, black markets, and harm to consumers.

The debate also overlooks the existing competitive forces within the credit card market. Numerous cards already offer 0% introductory APRs for extended periods, providing consumers with opportunities to borrow at lower rates. Economist Stephen Moore argues that the current system is functioning effectively and does not require government intervention. He contends that credit cards are more popular than ever, and regulations that reduce profitability and increase risk threaten this well-established market.

The proposal has drawn criticism from across the political spectrum. While some Democrats support the idea as a consumer protection measure, several Republicans, including Senators Mike Rounds and Pete Ricketts, House Speaker Mike Johnson, and Senate Majority Leader John Thune, have expressed strong reservations. Senator Thune correctly pointed out that the cap “would probably deprive an awful lot of people access to credit around the country.”

the argument against a credit card interest rate cap centers on the principle of free market competition. Proponents of this view believe that government intervention should focus on ensuring transparency, fostering competitive markets, and maintaining systemic stability, rather than dictating prices. As Kevin Brady, a former U.S. Representative from Texas, notes, free markets consistently deliver better products, services, and choices to consumers than government price-setting.

The current proposal echoes long-standing calls from Senators Elizabeth Warren and Bernie Sanders, and Representative Maxine Waters for interest rate caps. However, the potential for unintended consequences – reduced credit availability and increased costs for consumers – remains a significant concern for many in the financial industry and among Republican lawmakers.
