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.

Howard Marks warns that during a downturn, private credit managers may avoid recognizing defaults by simply extending loan terms for struggling companies. This 'extend and pretend' strategy can mask underlying problems, keeping assets marked artificially high and delaying a painful reckoning for investors.

Default rates are not uniform. High-yield bonds are low due to a 2020 "cleansing." Leveraged loans show elevated defaults due to higher rates. Private credit defaults are masked but may be as high as 6%, indicated by "bad PIK" amendments, suggesting hidden stress.

The most imprudent lending decisions occur during economic booms. Widespread optimism, complacency, and fear of missing out cause investors to lower their standards and overlook risks, sowing the seeds for future failures that are only revealed in a downturn.

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.

Historically, lower-quality credit cycles involved periods of high returns followed by giving all the gains back in a downturn. Post-GFC, the absence of a sustained recession has allowed private credit to outperform high-quality bonds by 7% annually without the typical "give it all back" phase, masking latent risks.

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.

Official non-accrual rates understate private credit distress. A truer default rate emerges when including covenant defaults and 'bad' Payment-in-Kind interest (PIK) from forced renegotiations. These hidden metrics suggest distress levels are comparable to, if not higher than, public markets.

Unlike past recessions where defaults spike and then recede, the current high-rate environment will keep financially weak 'zombie' companies struggling for longer. This leads to a sustained, elevated default rate rather than a sharp, temporary peak, as these firms lack the cash flow to grow or refinance.
