Wall Street Banks Brace for Impact as Trump Considers Caps on Credit Card Interest Rates – Thursday, January 15, 2026

Wall Street banks are preparing for the possibility of credit card price controls as former President Donald Trump considers capping interest rates. Such a move could fundamentally reshape the financial landscape, compelling banks to develop strategies to mitigate the impact of these potential regulatory changes.

Who should care: CFOs, fintech product leaders, payments executives, risk & compliance teams, and financial services technology decision-makers.

What happened?

Wall Street banks are on high alert as former President Donald Trump weighs the introduction of caps on credit card interest rates. This potential regulatory shift has triggered defensive strategizing among banks aiming to safeguard their critical revenue streams. Credit card businesses represent a substantial portion of bank profitability, and any imposed interest rate limits could force significant operational adjustments. The proposal gains momentum amid growing alignment between merchants and Trump, with merchants viewing interest rate caps as a way to lower transaction costs and strengthen their influence in financial policy debates. This emerging alliance intensifies pressure on banks, which are already navigating an environment of heightened regulatory scrutiny. Complicating matters further, banks may challenge any imposed controls through legal avenues, anticipating potential lawsuits to protect their interests. The financial sector is closely monitoring these developments, recognizing that a cap on credit card interest rates could have wide-reaching consequences—from compressing bank revenues to restricting consumer credit availability and altering lending behaviors across the industry.

Why now?

This potential regulatory intervention comes amid a broader trend of escalating scrutiny on financial institutions. Over the past 18 months, political shifts and growing consumer advocacy for fairer credit practices have driven a move toward more stringent financial regulations. The increasing alignment between merchants and regulatory interests reflects a notable shift, where non-financial stakeholders are asserting greater influence over financial policy to reduce their operational costs. This convergence of interests creates a conducive environment for regulatory action, making the current moment particularly ripe for discussions around credit card interest rate caps.

So what?

The prospect of credit card price controls carries significant implications for the banking sector. Strategically, banks may need to reevaluate their credit card business models and explore alternative revenue streams to offset potential declines. This could accelerate a shift toward more diversified financial products and services, reducing reliance on interest income from credit cards. Additionally, the growing alliance between merchants and regulators signals a potential realignment of power dynamics, with merchants gaining increased influence over financial policies that directly affect their costs. For banks, this means adapting to a landscape where traditional revenue sources face new constraints and stakeholder pressures intensify.

• For CFOs: Assess the financial impact of potential interest rate caps on revenue and profitability, and plan accordingly.
• For fintech product leaders: Innovate and develop products designed to succeed within tighter regulatory frameworks.
