President Trump has called for a one-year cap on credit card interest rates (APRs) at 10%, starting Jan. 20, 2026. The idea resonates because most credit cards currently charge APRs above 20%, and Americans collectively hold about $1.23 trillion in credit card debt.
If a 10% cap actually took effect, it could meaningfully reduce interest costs for millions of households. But there are major practical hurdles — and experts say the proposal is unlikely to become a real, enforceable policy in the near term.
Below is what a cap could do, what could go wrong, and what you can do now regardless of what happens in Washington.
How a 10% cap could affect cardholders
Credit card interest mostly matters if you carry a balance from month to month. Here’s the basic mechanic:
- Your card has an APR (annual percentage rate).
- The issuer typically calculates interest daily (based on a daily rate derived from the APR).
- That interest is added to your balance if you don’t pay the statement balance in full.
A lower APR can reduce the “drag” of interest, helping more of each payment go toward the principal.
A simple example of the potential savings
CBS News used a straightforward comparison:
- A $5,000 revolving balance at about 24% APR costs roughly $100 per month in interest.
- The same $5,000 balance at 10% APR costs roughly $41 per month in interest.
That’s about $59 per month back in a consumer’s budget — assuming the cap applied and the person continued carrying the same balance.
Researchers at Vanderbilt have estimated a 10% cap could reduce consumer interest costs by roughly $100 billion per year.
Key takeaway: The savings could be real — but only if a cap is actually implemented and enforced.
Why experts say it may be hard to implement
Even though presidents can shape policy priorities, they generally can’t set prices for private companies by announcement alone.
As of now, there is:
- No law passed by Congress that creates a national 10% credit card APR cap.
- No finalized federal regulation that imposes a 10% credit card APR cap.
- No clear legal pathway for a nationwide cap to go into effect immediately.
In practice, a cap would likely require Congressional legislation, a detailed rulemaking process, or some other authority that would almost certainly be challenged in court.
Bottom line: Based on how federal laws and regulations work, a 10% cap is unlikely to take effect soon, even if it remains part of the political conversation.
The role of the CFPB
The Consumer Financial Protection Bureau (CFPB) is the federal consumer watchdog created in 2010 to oversee financial products — including credit cards — and to protect consumers from unfair or abusive practices.
Why does that matter here? Because rulemaking is one of the main ways consumer finance rules are actually changed in the real world.
For example, under the Biden administration, the CFPB used the rulemaking process to finalize a rule that would have capped most credit card late fees at $8, relying on authority under the 2009 CARD Act.
But:
- Banks sued to block the late-fee rule.
- The Trump administration sided with banks and rescinded the $8 cap effort.
- The administration has also moved to reduce the CFPB’s capacity by cutting staff and limiting oversight work.
Why this matters for the 10% APR proposal: The main federal agency most directly positioned to write and enforce consumer-focused credit card rules is now significantly weakened, which further reduces the odds of a rapid, enforceable APR cap.
Industry concerns and historical context
Banks and industry groups argue a hard cap could create trade-offs for consumers, including:
- Tighter credit approvals, especially for higher-risk borrowers.
- Reduced credit limits or account closures.
- Fewer rewards, smaller sign-up bonuses, or higher annual fees if interest revenue falls.
The Electronic Payments Coalition has warned that price controls could shrink access to credit and compared the proposal to past policy failures.
“We have seen this movie before. When President Carter imposed similar price controls in 1980, credit dried up, costs rose, and the economy slid into recession. Repeating that failed experiment today would be both reckless and devastating.”
That argument reflects a broader concern: if lenders can’t price risk, they may lend less — or shift costs elsewhere.
At the same time, it’s important to note the differences:
- Carter-era controls were broader and affected multiple forms of credit.
- Today’s discussion is specifically about credit card APRs.
What consumers can do now
Because a 10% cap is uncertain and faces significant hurdles, it’s best not to plan your debt payoff strategy around it.
Instead, focus on steps that can reduce interest costs today:
- Consider a 0% intro APR balance transfer (if you qualify), and aim to pay it off before the promo period ends.
- Ask your current issuer for a lower APR — it’s not guaranteed, but it can work for strong payment history.
- Pay extra toward your highest-APR balance first (the “avalanche” method).
- Watch for changes to rewards and fees if regulation advances and issuers adjust pricing.
Bottom Line
A 10% APR cap could lower borrowing costs if it ever becomes real policy. But for now, it’s best viewed as a proposal with an unclear path — and your most reliable savings still come from lowering your current APR, reducing balances, and paying strategically.
