Capping credit card interest rates at 10% sounds appealing on the surface, but here's the reality: lenders can't sustain business models without rates that adequately cover defaults and generate sufficient returns on capital. When you restrict pricing power that dramatically, financial institutions don't just absorb losses—they exit. What happens next? Consumers lose access to credit entirely. Card issuers will tighten approval criteria or simply cancel programs. It's a textbook example of how well-intentioned policy can backfire. The real challenge isn't the interest rate ceiling itself, but understanding the mechanics of credit risk pricing. Remove the ability to charge rates that reflect actual risk, and the market contracts. That's not conspiracy—that's basic financial economics.
