A guest reveals the severe, cascading costs of a poor credit score (in the 400-500 range). Beyond loan denials, it functioned as a tax on his life, inflating his car loan interest rate to a staggering 28% and significantly increasing his monthly insurance premiums for the same coverage.

The same banks issuing high-interest credit cards offer substantially cheaper personal lines of credit to customers with identical FICO scores. Despite being a logical tool for consolidating expensive card debt, these products receive almost no marketing, making them largely invisible to consumers.

PNC's CEO explains that even at an average rate of 18%, the net margin on credit cards is only around 4% after accounting for rewards, losses, and funding costs. Capping rates at 10% would turn this margin negative, forcing issuers to exit the business and cutting off consumer credit access.

While many assume high credit card rates cover default risk, actual charge-offs on revolving balances average only 5.75%. This is a significant cost but accounts for less than a third of the typical interest rate spread, indicating that other factors like risk premiums and operating costs are major drivers.

A proposed 10% cap on credit card interest rates, while intended to improve affordability, would likely have the opposite effect. This policy would probably force lenders to tighten credit standards to offset lower profitability, ultimately restricting credit access for the very subprime consumers and balance-carriers it aims to help.

The dramatic rise in BNPL usage across all demographics, including 41% of young shoppers, is a negative forward-looking indicator. While framed as innovation, it's a form of modern usury that reveals consumers cannot afford their purchases, creating a significant, under-discussed credit risk for the economy.

A government-imposed cap on credit card interest rates would make the business model unviable for most customers due to risk-reward dynamics. Banks would be forced to deny cards to anyone but the lowest-risk individuals, effectively canceling access to credit for the majority of the population.

Consumers are largely insensitive to the interest rates they are charged, rarely seeking out cheaper options like credit union cards. This behavioral pattern means that cutting rates is an ineffective customer acquisition strategy. Instead, issuers invest heavily in marketing, which proves more effective at attracting new borrowers.

Affirm's CEO argues the core flaw of credit cards is not high APRs, but a business model that profits from consumer mistakes. Lenders are incentivized by compounding interest and late fees, meaning they benefit when customers take longer to pay and stumble.
