Today we wanted to examine credit card revenues in particular. If the Trump Administration follows through on President Trump’s demand that interest rates for consumer credit cards be capped at 10 percent, what might that mean for the credit card revenue that banks receive?

Figure 1, below, gives us a preliminary sense of the money involved. It shows quarterly credit card revenue from Bank of America ($BAC), Citigroup ($C), JPMorgan Chase ($JPM), and Wells Fargo ($WFC) for the last three years. 

As you can see, we’re talking about multiple billions of dollars, although Citi’s billions are far larger than any of the other banks. You can find these numbers easily by searching the banks’ footnotes via our Disclosures and Footnotes Query page and using the See Tag History feature.

More Data, More Analysis

But that only gives us a sense of the sums involved. To understand how a cap on credit card fees might affect bank business, you need to dig further. Using our Multi-Company page, we also excavated total non-interest income for all four banks and then compared those numbers to card income for 2025. See Figure 2, below.

Not only does Citi generate more card income than any of its peers; Citi also has a bigger portion of its non-interest income tied up in credit cards too. So in a world where the Fed cuts interest rates and the Trump Administration somehow forces a cap on credit card rates, that could leave Citi in a bind more difficult than what its peers might face.

Will that scenario come to pass in 2026? We don’t know. But we can arm analysts with the best information so that you can ponder the question as fully as possible.
