If you’re carrying a balance on your credit card, you know the pain of watching interest charges eat up your monthly payments. With average interest rates hovering near record highs, the idea of a government-mandated cap sounds like a financial lifeline.
President Trump recently proposed a temporary 10% cap on credit card interest rates. On the surface, this looks like a massive win for consumers — a chance to slash debt and keep more money in your pocket. However, in the world of finance, simple solutions often come with complex consequences.
While the proposal aims to help Americans struggling with debt, financial experts and economists warn it could fundamentally change how credit cards work, potentially making it harder to get a card or keep your rewards.
Here are five things you need to know about the proposed 10% cap.
1. It would cut current rates in half
To understand the magnitude of this proposal, you have to look at where we are right now. The average credit card interest rate is currently over 20%, with many store cards and subprime cards charging significantly more.
A 10% cap isn’t just a small trim; it is a slash-and-burn reduction. For someone with $5,000 in credit card debt, dropping the rate from 20% to 10% would save them roughly $500 a year in interest alone. That is real money that could go toward groceries, savings, or paying down the principal balance faster.
However, that math assumes you get to keep your card and your credit limit remains the same. That leads us to the unintended consequences.
2. It might cut your access to credit
Banks and credit card issuers are businesses, not charities. They set interest rates based on risk. If they lend money to someone with a lower credit score, they charge a higher interest rate to offset the higher chance that the person might not pay them back.
If the government forbids them from charging a rate that matches that risk, banks will simply stop lending to “risky” borrowers.
A study from Vanderbilt University suggests that while banks could technically afford to absorb some of these cuts, the industry rarely absorbs costs willingly. Instead, they tighten their belts. The Associated Press reports that such a cap could force lenders to pull back, potentially rejecting millions of applicants who would have qualified under the old rules.
If your credit score is below 700, you might find it impossible to get a new card, or you might see your current credit limits slashed overnight.
3. Rewards programs could disappear
If you love your cash back, airline miles, or dining points, pay close attention. Those rewards aren’t free gifts; they are funded largely by the interest and fees that other customers pay.
When you cap interest rates at 10%, you remove a massive chunk of revenue that banks use to subsidize these perks. To protect their profit margins, issuers would likely gut rewards programs.
We have seen this movie before. When Congress capped debit card swipe fees years ago, debit card rewards programs virtually vanished. If this credit card cap becomes law, the golden era of 2% cash back and lucrative sign-up bonuses could come to an abrupt end.
4. Banks will find other ways to charge you
When one door closes, banks usually open a window — and then charge you a fee to look through it. If interest income dries up, issuers will look for new ways to generate revenue.
We could see a return to the days where almost every credit card carried an annual fee, regardless of the perks. You might also see higher fees for late payments, balance transfers, or even foreign transactions. The “free” credit card that you pay off every month to build credit could become a product that costs you $50 or $100 a year just to keep in your wallet.
5. It faces a tough legal road
Finally, it is important to remember that a President cannot simply sign a piece of paper and change the interest rates of private banks.
Implementing a federal usury cap (a limit on interest rates) requires an act of Congress. While there is some bipartisan support for capping rates — Senator Bernie Sanders and Senator Josh Hawley have pushed for similar measures — there is also immense opposition from the banking lobby and free-market lawmakers.
Even if it passes Congress, it would almost certainly face immediate legal challenges from the financial industry. So, while the headline is grabbing attention, the reality of a 10% cap hitting your statement anytime soon is far from guaranteed.
What you should do now
Regardless of what happens in Washington, the math on credit card debt never changes: it is an emergency. Don’t wait for a government bailout that may never come.
If you have high-interest debt, focus on paying it down now. Look into a balance transfer card with a 0% introductory rate (while they still exist) or consider a personal loan to consolidate your debt at a fixed rate.

The best interest rate is always 0% — the rate you pay when you have no debt at all.
