President Donald Trump’s promise to cap credit card interest at 10% for a year landed like a lifeline for millions of Americans carrying balances at two or three times that rate. The idea taps into real anger over double digit annual percentage rates that barely budged even as other borrowing costs fell. But a closer look at the legal mechanics and the economics of price caps suggests the reality will be far messier than the sound bite.
The core question is not whether a 10% ceiling sounds appealing, but whether it can be delivered without shrinking access to credit or pushing borrowers into even costlier corners of the market. I see Trump’s plan as a kind of financial rent control: it might cut the price for some households, yet it risks leaving others locked out entirely. The stakes are high, because the wrong design could leave the most vulnerable cardholders worse off than they are today.
What Trump actually promised, and what the law says today
Trump has repeatedly said credit card companies should not be allowed to charge more than 10% interest for one year, framing it as emergency relief for households weighed down by revolving balances. In a televised appearance, President Trump described the cap as a straightforward directive, implying that issuers would have to comply or face consequences. He has tied the idea to a specific deadline in Jan, telling supporters that lenders should have brought rates down by Jan 20 or risk being “in violation of the law.”
The problem is that, as of now, there is no federal statute that actually imposes such a ceiling. A detailed fact check found that when Trump said card companies would be breaking the law if they failed to cut rates to 10% by Jan 20, that claim was inaccurate, because Congress has not passed any measure creating that obligation and regulators have not issued a binding rule to that effect. The review concluded that Trump was describing an aspiration, not an enforceable requirement.
The Sanders–Hawley blueprint behind the rhetoric
Trump’s language did not emerge in a vacuum. The 10% figure closely mirrors a bipartisan proposal in the Senate known as the 10% Credit Card Interest Rate Cap Act, introduced by Sen. Bernie Sanders and Sen. John Hawley. That bill would limit most card APRs to 10% nationwide, effectively overriding higher state usury limits and reshaping how banks price unsecured consumer credit. It is this legislative template that Trump has pointed to when he talks about forcing lenders to slash rates for a year.
Sanders, an independent from Vermont, and Hawley, a Republican from Missouri and longtime Trump ally, have framed their bill as a way to stop what they see as gouging on everyday borrowing. An explainer on the proposal notes that Bernie Sanders and John Hawley are pitching the cap as a way to deliver debt relief quickly, especially for cardholders paying APRs well above 20%. Yet even supporters concede that the measure would face intense lobbying resistance from banks and card networks, which rely heavily on interest income from revolving balances.
Why your rate has not dropped to 10%
For consumers watching their statements, the most obvious disconnect is that nothing like a universal 10% rate has appeared. When Jan 20 arrived, reporters checked with major issuers and found that card APRs remained far above Trump’s target, even as some lenders modestly trimmed rates in response to broader monetary policy. One analysis noted that credit card rates had been drifting lower over the past year, thanks in part to the Federal Reserve’s 2025 rate cuts, but they were still nowhere near 10% for typical borrowers.
Trump’s own allies have acknowledged that his Jan deadline was more political pressure than legal line in the sand. Coverage of the rollout highlighted that President Donald Trump called for the cap and then criticized card companies for ignoring him, but there was no regulatory text or signed statute to enforce his demand. In practice, issuers have treated the proposal as a political signal rather than a binding rule, adjusting only where market forces and risk models already pointed them.
How a 10% ceiling would collide with bank economics
To understand why the industry is pushing back so hard, it helps to look at how card lending actually works. Issuers price APRs to cover expected losses from defaults, funding costs, rewards programs, fraud, and profit margins. For subprime borrowers, those expected losses are high, which is why their APRs often sit in the mid 20s or higher. Forcing all accounts down to 10% would compress that spread dramatically, especially for riskier segments, and would likely prompt banks to cut back on approvals or reduce credit limits.
Analysts who model card portfolios have warned that a one year cap could wipe out a sizable share of interest revenue, particularly for lenders that specialize in store cards and co branded products. A breakdown of the proposal’s impact on the payments ecosystem found that President Donald Trump would be hitting companies like Capital One and Synchrony especially hard, because they sit in the middle of the risk spectrum and depend heavily on interest income. That is why some bank executives, including Morgan leaders, have labeled the plan a “disaster” for their business models and warned of knock on effects for credit availability.
Lessons from price caps: rent control for your wallet
Economists often compare interest rate ceilings to rent control, and the analogy fits here. When governments cap apartment rents below market levels, tenants who keep their units benefit, but landlords may convert properties to other uses or stop building new housing, which reduces supply over time. A 10% APR limit would similarly help borrowers who already qualify for prime cards, while giving issuers a reason to pull back from marginal customers whose risk cannot be priced properly at that level.
Research on previous rate caps in other countries shows that when regulators clamp down on one form of high cost credit, lenders and borrowers often migrate to less regulated products. One assessment of Trump’s idea noted that UBS expects some card programs to be cancelled outright if a strict 10% ceiling is imposed, especially those serving higher risk customers. That would not erase the underlying need for short term borrowing; it would simply push it into channels like payday style loans, buy now pay later plans, or informal lending, where protections can be weaker and costs less transparent.
