Unlocking $100 Billion Savings: The Truth About Credit Card Rate Caps
Discover how capping credit card interest rates at 10% could save Americans $100 billion annually, reshape rewards, and challenge banking myths in this deep dive into credit card reform.
Key Takeaways
- Capping credit card rates at 10% could save Americans $100 billion yearly.
- Banks remain profitable by relying on interchange fees despite rate caps.
- Rewards programs may shrink mainly for riskier borrowers, not all cardholders.
- Average U.S. credit card interest rates have nearly doubled in a decade.

Imagine slicing your credit card interest bill nearly in half overnight. That’s the promise behind a bold proposal to cap credit card interest rates at 10%, a plan championed by former President Donald Trump during his 2024 campaign and now echoed in bipartisan bills in Congress. With Americans carrying a staggering $1.21 trillion in credit card debt—roughly $6,400 per person—and average interest rates soaring to about 22%, the stakes couldn’t be higher.
A Vanderbilt University study sheds fresh light on this debate, revealing that such a cap could save consumers up to $100 billion annually without sinking banks into the red. The research challenges the banking industry’s long-held warnings of doom, showing that banks could still turn a profit by leaning on merchant fees and adjusting rewards programs selectively.
This article unpacks the real impact of capping credit card interest rates, explores the political tug-of-war shaping this issue, and debunks myths that have kept high rates in place for decades. Ready to rethink what you know about credit card costs? Let’s dive in.
Exploring Credit Card Debt
Picture this: Americans owe $1.21 trillion on credit cards, averaging about $6,400 each. That’s a mountain of debt casting a long shadow over household budgets. The average interest rate? A hefty 21%—almost double what it was a decade ago. It’s no wonder many feel trapped in a cycle of revolving debt.
Bo, a fictional but relatable cardholder, once juggled payments with a 22% rate. Each month, the interest felt like a sneaky tax on his paycheck. The sting of an empty savings account made it worse. His story echoes millions who face similar struggles.
This backdrop sets the stage for proposals to cap interest rates. The idea is simple: lower rates mean less interest paid, more breathing room, and a chance to break free from debt’s grip. But how realistic is this? Let’s unpack the numbers and myths next.
Unpacking Interest Rate Caps
Interest rate caps aren’t new—they trace back to ancient usury laws, even mentioned in the Bible. Today, the proposal to cap credit card rates at 10% is gaining traction again, thanks to political figures like Donald Trump, Bernie Sanders, and Josh Hawley.
The Vanderbilt University paper reveals that capping rates at 10% could save Americans $100 billion annually. Even a 15% cap would save $48 billion. These aren’t small change—they’re transformative sums that could ease financial stress for millions.
Banks argue that such caps would wreck their business models, threatening rewards programs and profitability. But the study challenges this narrative, showing banks can still profit by relying on interchange fees—the charges merchants pay when you use your card. This fee stream funds many rewards, meaning banks don’t solely depend on high interest rates.
So, the cap isn’t a financial apocalypse for banks, but a potential lifeline for consumers.
Evaluating Banking Industry Claims
The banking industry paints a grim picture: cap interest rates, and credit cards become unprofitable. Rewards vanish. Credit dries up. But is this the whole story?
Brian Shearer, the Vanderbilt researcher and former Consumer Financial Protection Bureau strategist, dug into these claims. His findings? Banks would still turn a profit on most customers even with a 15% cap, and at 10%, profitability remains for many by trimming some rewards.
Rewards programs, often seen as freebies, are mostly funded by interchange fees, not interest. American Express, for example, earned $35.2 billion from merchant fees alone. This revenue cushion means banks don’t have to rely entirely on sky-high interest rates.
The biggest impact on rewards would hit cardholders with low credit scores—the riskiest borrowers. Yet, these customers often carry balances and pay more interest, so the savings from lower rates could offset reduced perks. The banking doom narrative doesn’t capture this nuance.
Legislative Momentum and Public Support
The idea of capping credit card interest rates has crossed party lines. Senators Bernie Sanders and Josh Hawley introduced bills mirroring Trump’s 10% cap proposal. Representative Alexandria Ocasio-Cortez pushed a similar measure in the House.
Public sentiment backs this move strongly—77% of Americans support a cap, even if it means fewer rewards. This reflects widespread frustration with soaring credit card costs amid a tough economic climate.
Yet, the financial services industry fights back fiercely. Giants like Visa, MasterCard, and American Express lobby hard to block these bills. They argue that caps would reduce credit availability, especially for riskier borrowers, potentially pushing them toward costlier payday loans or other alternatives.
The battle lines are clear: consumer relief versus industry profits. The outcome will shape credit access and affordability for years.
Navigating Consumer Impact
For everyday Americans, what does a 10% cap mean? Imagine paying half the interest on your credit card balance. That’s real money staying in your pocket—money that can fund emergencies, education, or a much-needed vacation.
However, some trade-offs exist. Banks might reduce rewards, especially for those with lower credit scores. Credit access could tighten for riskier borrowers, who might find it harder to get cards or face stricter terms.
Still, the Vanderbilt study suggests these changes won’t be catastrophic. The savings from lower interest rates could outweigh reduced perks for many. And with credit unions already capping rates at 18%, and the Military Lending Act limiting rates to 36% for service members, precedent exists for protecting consumers.
Ultimately, this debate is about balancing fair costs with credit availability—a delicate dance with millions watching.
Long Story Short
Capping credit card interest rates at 10% isn’t just a political talking point—it’s a potential game-changer for millions of Americans drowning in debt. The Vanderbilt study’s $100 billion savings figure paints a compelling picture of relief, especially for those with average or subprime credit scores who currently face punishing rates. Yet, this isn’t a silver bullet. Banks may trim rewards for riskier borrowers and tighten credit access, which could shift some consumers toward costlier alternatives. Still, the banking industry’s apocalyptic warnings don’t fully hold up under scrutiny. Interchange fees provide a robust revenue stream that cushions banks against interest rate cuts, allowing them to remain profitable while easing consumer burdens. The bipartisan legislative push reflects growing public demand—77% of Americans support such caps—even if the path forward is tangled in lobbying battles. For consumers, understanding these dynamics empowers smarter choices and sharper advocacy. The relief of a funded emergency account or lower interest payments isn’t just financial—it’s emotional freedom. As this debate unfolds, staying informed and engaged will be key to unlocking a fairer credit card landscape.
