President Donald Trump’s proposal to impose a 10% cap on credit card interest rates is drawing sharp criticism from the U.S. banking industry, with JPMorgan Chase executives warning the move could significantly reduce access to credit and potentially lead to legal action.
The proposal, which Trump said would begin Jan. 20 for a one-year period, has reignited debate over price controls in consumer finance and their unintended economic consequences.
JPMorgan Warns of Major Business Impact
Speaking as JPMorgan reported fourth-quarter earnings, Chief Financial Officer Jeremy Barnum said a mandated interest cap would force the bank to “significantly change and cut back” its credit card operations.
According to Barnum, the policy would not lower the cost of borrowing in practice, but instead reduce the overall supply of credit, particularly affecting consumers who rely most on revolving credit.
Rather than benefiting consumers, he argued, such a cap could harm households, the broader economy, and banks alike by making credit uneconomical to offer at scale.
Legal Action Not Ruled Out
Barnum did not rule out the possibility that the banking industry could challenge the policy in court if it is imposed without sufficient legal grounding.
He noted that directives requiring banks to fundamentally restructure profitable business lines could leave lenders with little choice but to consider litigation, particularly if implementation lacks legislative backing.
The comments echo prior industry responses during the Biden administration, when bank trade groups sued the Consumer Financial Protection Bureau over efforts to cap late fees and overdraft charges.
Competitive Credit Card Market at Risk
JPMorgan executives emphasized that the U.S. credit card market is already highly competitive, spanning borrowers from high to low credit scores.
Barnum stressed that if price controls make card lending unattractive, issuers would respond by tightening approval standards, cutting limits, or exiting certain segments altogether.
A 10% cap, he said, would fundamentally change how credit card services are provided, leading to widespread loss of access rather than modest margin compression.
Disproportionate Impact on Subprime Borrowers
JPMorgan CEO Jamie Dimon added that subprime borrowers would likely bear the brunt of the policy’s effects.
While a modified version of the proposal could soften the impact, Dimon warned that a strict implementation as described would be “dramatic,” especially for consumers with weaker credit profiles who already face limited options.
Uncertainty Around Implementation
Bank executives and analysts alike highlighted the lack of detail surrounding Trump’s proposal. Beyond social media statements and public remarks, there is little clarity on enforcement mechanisms or legal authority.
Analysts covering major banks have noted that such a cap would likely require legislation, which faces steep odds of passage. Still, Trump reportedly warned that issuers could be “in violation of the law” if they fail to comply with the proposed deadline.
Broader Regulatory Pressure on Card Issuers
Trump has also voiced support for the Credit Card Competition Act, which targets interchange fees earned by card networks and issuing banks. Industry groups representing banks and credit unions have already pushed back against that effort as well.
Together, these proposals signal renewed political scrutiny of the credit card ecosystem, even as banks continue to expand their card portfolios.
JPMorgan Expands Card Business Despite Policy Risks
Despite regulatory uncertainty, JPMorgan is moving forward with major investments in the card space. The bank recently agreed to take over issuance of the Apple Card, absorbing a $20 billion portfolio from Goldman Sachs.
Executives described the deal as economically attractive and strategically aligned, though integration is expected to take up to two years due to technology and infrastructure requirements.
Outlook: Policy Debate Far from Settled
While Trump’s interest cap proposal has sparked intense debate, significant questions remain around legality, enforcement, and economic impact.
For now, banks are preparing for multiple scenarios, balancing expansion plans with the risk that aggressive price controls could reshape the U.S. credit card market and push the industry toward legal confrontation.
