Large banks have offloaded riskier loans to private credit, which is now more accessible to retail investors. According to Crossmark's Victoria Fernandez, this concentration of risk in a less transparent market, where "cockroaches" may be hiding, is a primary systemic concern.

Contrary to the common perception of users paying off balances monthly ("transactors"), the majority—about 60%—are "revolvers" who carry debt. This group is the primary source of profit for card issuers, as they are subject to interest rates now averaging a staggering 23%.

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.

Senator Warren highlights a critical omission in standard economic calculations: the cost of servicing debt. Expenses like credit card interest and student loan payments are often left out, meaning official data doesn't capture the full financial pressure American families are facing.

Despite a 9.1% year-over-year increase in nominal sales, Black Friday data reveals consumers bought 4.1% fewer items and dramatically increased their use of "Buy Now, Pay Later" services. This indicates that inflation, not strong consumer health, is driving top-line revenue growth for corporations.

The credit market appears healthy based on tight average spreads, but this is misleading. A strong top 90% of the market pulls the average down, while the bottom 10% faces severe distress, with loans "dropping like a stone." The weight of prolonged high borrowing costs is creating a clear divide between healthy and struggling companies.

Recent stress in credit card and auto loan markets is concentrated in loans originated in 2021-2023 when stimulus and looser standards prevailed. Lenders have since tightened, and newer loan portfolios are performing better, suggesting the problem is not spreading systemically.

Contrary to theories that recent blow-ups like Tricolor indicate more fraud is coming, the real issue is broad economic stress. Using Warren Buffett's "tide goes out" analogy, higher rates and persistent inflation are exposing fundamental weaknesses and squeezing consumers across large, non-AI sectors of the economy.

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.
