President Donald Trump dropped a bombshell on the financial industry last week when he called for credit card interest rates to be capped at 10% for one year, beginning January 20, 2026. The proposal sent bank stocks tumbling, sparked fierce debate among economists, and left millions of cardholders wondering what it could mean for their finances.

With the average credit card interest rate currently hovering around 22%, a 10% cap would represent the most dramatic intervention in consumer lending since the financial crisis. But whether such a cap is achievable—and what unintended consequences it might create—remains deeply uncertain.

The Current Landscape

Americans owe a record $1.23 trillion in credit card debt, according to the Federal Reserve Bank of New York. The average interest rate on accounts carrying balances stands at approximately 22.30%, up sharply from 16.28% in 2020. These rates reflect a combination of factors:

  • Federal Reserve Policy: The Fed's aggressive rate hikes in 2022-2024 pushed borrowing costs higher across the economy, including credit cards.
  • Risk Pricing: Credit card lending is unsecured, meaning banks have no collateral to recover if borrowers default. Higher rates compensate for this risk.
  • Delinquency Trends: Credit card delinquencies have risen to decade highs, prompting lenders to maintain elevated rates to offset losses.

"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%."

Implementation Questions Abound

Trump's announcement left crucial details unaddressed. The president did not specify whether the cap would be implemented through executive action or require legislation—a distinction with profound implications for feasibility.

Industry experts are skeptical that an executive order could impose binding rate caps on private lenders. Credit card interest rates are governed by a complex web of federal and state laws, bank regulations, and contractual agreements. Unilaterally capping rates would likely face immediate legal challenges.

Legislative action would face its own hurdles. While the proposal has attracted bipartisan support—Senators Bernie Sanders and Josh Hawley introduced a similar bill in 2025—passing such legislation through Congress would require overcoming fierce industry opposition.

The Bank Response

Financial industry groups have warned that a 10% rate cap would "reduce credit availability and be devastating for millions of American families and small business owners." Their argument: at a 10% rate, banks cannot profitably lend to higher-risk borrowers, who would lose access to credit entirely.

Bank stocks fell sharply on the announcement. Capital One dropped 7%, Citigroup fell 3%, and Synchrony Financial—which specializes in store credit cards—saw double-digit percentage declines. The market reaction suggests investors take the threat seriously, even if implementation remains unclear.

Industry insiders warn of potential consequences:

  • Credit Contraction: Lenders would stop offering cards to subprime borrowers, who rely on credit cards for emergency expenses and cash flow management.
  • Rewards Elimination: Cash back, points, and travel rewards programs would likely be scaled back dramatically, as issuers couldn't afford them at lower rates.
  • Annual Fee Increases: Cards that currently carry no annual fee might add fees to compensate for lost interest income.
  • Credit Limit Reductions: Existing cardholders could see their limits cut to reduce bank exposure.

Who Would Benefit?

If a rate cap were successfully implemented, the immediate beneficiaries would be cardholders currently carrying high-interest balances. A borrower with $10,000 in credit card debt at 22% interest pays approximately $2,200 annually in interest charges. At 10%, that drops to $1,000—meaningful savings for struggling households.

However, these benefits assume cardholders can maintain their current credit access. If banks respond by closing accounts or denying new applications, some consumers would be worse off despite lower rates on paper.

Buy Now, Pay Later Winners

One clear winner from the credit card turmoil: buy now, pay later (BNPL) companies. Affirm, Klarna, and similar services have surged as investors bet that rate caps would push consumers toward alternative financing. BNPL providers typically charge merchants rather than consumers, potentially allowing them to operate outside rate cap restrictions.

The irony is that BNPL arrangements often carry effective interest rates comparable to credit cards when accounting for late fees and other charges. Consumer advocates worry that regulatory efforts focused on traditional credit cards could inadvertently push borrowers toward less regulated alternatives.

What Cardholders Should Do Now

Regardless of whether Trump's proposal becomes reality, cardholders can take steps to improve their financial position:

  • Pay Down Balances: High-interest debt is costly regardless of the regulatory environment. Prioritize paying off credit card balances.
  • Shop for Better Rates: Balance transfer offers and lower-rate cards remain available for borrowers with good credit. Don't assume your current rate is the best you can get.
  • Build Emergency Savings: Reducing reliance on credit cards for emergencies protects you from rate volatility and potential credit access restrictions.
  • Monitor Your Credit: Strong credit scores provide access to better terms. Regularly check your credit report and address any issues.

The Road Ahead

Trump's credit card rate cap proposal reflects genuine frustration with consumer borrowing costs that have risen sharply during his second term. Whether the policy becomes reality, triggers legislation, or fades as a talking point remains to be seen.

For the financial industry, the uncertainty alone is damaging. Banks must now model scenarios that could fundamentally alter their consumer lending businesses, potentially pulling back from credit extension as they assess the risks.

For consumers, the lesson is familiar: don't count on Washington to solve your debt problems. The most reliable path to financial health runs through personal decisions—spending less, saving more, and paying down high-interest debt. That advice holds whether credit card rates are capped at 10% or remain at 22%.
