The credit card industry went into high gear over the weekend following a social media post from President Donald Trump calling for a 10% cap on interest rates. This mirrors a pledge he made on the campaign trail, and it also aligns with a pair of proposed bills in Congress (one in the Senate and the other in the House) — though neither of these bills has seen any additional action since being referred to the chambers’ respective committees in early 2025.

While we have more questions than answers right now, here’s what you need to know about this development.

Social media post on Friday night

The topic resurfaced with a Friday night post from President Trump on his Truth Social platform, which included the following:

“Effective January 20, 2026, I, as President of the United States, am calling for a one year cap on Credit Card Interest Rates of 10%.”

The post didn’t detail the mechanics of implementing such a proposal, and no additional information has been shared as of the publication date. It’s also a very compressed timeline for implementation, with less than two weeks until the “effective” date.

In remarks aboard Air Force One over the weekend, President Trump noted that card issuers would “be in violation of the law” if they didn’t comply, though it remains to be seen what that actually means for issuing banks.

While Federal Reserve data shows that American households are now carrying roughly $1.23 trillion in credit card debt, many note that an interest rate cap would likely restrict banks’ ability to lend, especially to less creditworthy individuals.

A joint statement from banking industry trade groups noted the following:

“Evidence shows that a 10% interest rate cap would reduce credit availability and be devastating for millions of American families and small business owners who rely on and value their credit cards, the very consumers this proposal intends to help.”

One study from the Electronic Payments Coalition estimates that 82% to 88% of people (or about 175 to 190 million Americans) could lose access to credit with this type of cap.

TPG’s philosophy on interest rates

One of TPG’s core principles is to never carry a balance on your credit cards from one month to the next. By paying every monthly statement in full (and on time), you’ll avoid interest charges entirely. These fees can easily outweigh the value of any rewards you can earn, so it’s critical to spend within your means on your cards.

That’s why it’s crucial to understand the ins and outs of credit before opening any new credit card product. You can start with our beginners guide to credit cards and then dig deeper with the following stories to help build your knowledge:

If you do find yourself in credit card debt, there are several strategies you can employ to get back on track. You may even be eligible for a balance transfer card with another bank. For a small fee, you could unlock a period of time to pay down your balance with no interest.

Bottom line

President Trump has renewed his calls for a 10% cap on credit card interest rates, a move that could have massive implications for the credit card industry and Americans’ finances. However, the full details of how such a proposal would take effect remain to be seen.
