Trump's Credit Card Interest Cap: Why American Express Might Just Be Fine

When news broke that Donald Trump was floating the idea of capping credit card interest rates at a mere 10%, it's fair to say a few eyebrows shot up across the financial world. The initial knee-jerk reaction for many, myself included, was probably something along the lines of, "Wait, what? That's going to hit lenders hard!" But let's take a deep breath and really think this through, especially when we consider a player like American Express (AXP).

See, it’s easy to assume such a drastic cap would cripple the entire credit card industry. After all, those high interest rates are a significant revenue stream for many banks, right? And yes, they absolutely are. But not all credit card companies are built the same, and Amex, you know, has always marched to the beat of its own drum. They're a bit of an outlier, and understanding their unique setup is key to grasping why this proposed cap might not be the existential threat some are imagining for them.

Here’s the thing: American Express doesn’t lean nearly as heavily on interest income as many of its competitors do. Their business model is actually far more diversified. A huge chunk of their revenue, in fact the largest portion, comes from what are called 'discount revenue' or 'interchange fees.' This is the fee merchants pay to Amex every time a customer swipes their card. It's a fundamental difference, and it means their financial health isn't solely, or even primarily, tied to how much interest their cardholders are paying on outstanding balances.

Moreover, think about who typically carries an American Express card. We’re talking about a generally more affluent demographic here, people who are, by and large, pretty good at managing their finances. They often pay off their balances in full each month, or at least they’re more likely to do so than customers of other card networks. If you're paying your balance in full, a 10% interest cap, or even a 20% rate for that matter, is completely irrelevant to you because you're not paying any interest at all. This means Amex's core customer base is inherently less sensitive to fluctuations in interest rates.

It's also worth noting that Amex's effective interest rates, when you look at their overall portfolio, tend to be lower than many other card issuers. They’re simply not as heavily invested in the subprime lending market, which is where those eye-watering high-interest rates often come into play to offset higher risk. Their focus has always been on attracting and retaining premium customers, offering great rewards, and fostering loyalty, rather than maximizing interest income from high-risk borrowers.

We've actually seen something similar play out before. Remember the Durbin Amendment, which capped debit card interchange fees? Many predicted it would be the end of profitability for banks' debit card operations. While it certainly shifted things around and forced some adjustments, it hardly broke the banking system. Institutions adapted, found new revenue streams, and the world kept turning. There’s a certain resilience in these financial giants that often gets underestimated during policy scares.

So, while a 10% cap would undoubtedly send ripples through the broader credit card industry – and let’s be clear, some lenders, particularly those heavily focused on subprime borrowers, would face significant challenges – American Express looks relatively insulated. Their robust business model, their discerning customer base, and their revenue diversification mean that while they might feel a pinch, it’s highly unlikely to be the kind of existential threat that some policy changes could pose to others. It just underscores that in finance, as in life, one size rarely fits all.
