The term "middle market" is too broad for risk assessment. KKR's analysis indicates that default risk and performance dispersion are not uniform. Instead, they will be most pronounced in the lower, smaller end of the middle market, while the larger companies in the upper-middle market remain more resilient.

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 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.

The increase in Payment-In-Kind (PIK) debt to 15-25% of BDC portfolios is not a sign of innovative structuring. Instead, it often results from "amend and extend" processes where weakened companies can no longer afford cash interest payments. This "zombification" signals underlying credit deterioration.

In large loan portfolios, defaults are not evenly distributed. As seen in a student loan example, the vast majority (90%) of defaults can originate from a specific sub-segment, like for-profit schools, and occur within a predictable timeframe, such as the first 18 months.

Recent "canary in the coal mine" cases like First Brands, often blamed on private markets, were not PE-owned and were primarily financed in liquid markets. In fact, it was private credit firms pushing for deeper diligence that exposed the issues, strengthening the argument that private credit offers a safer way to access the asset class.

Aegon's Global Head of Leverage Finance, Jim Schaefer, shares a critical heuristic: once a leveraged loan's price falls below the 80-cent mark, it has a high probability of entering a formal restructuring. This price level acts as a key warning indicator for investors, signaling imminent and severe distress.

Despite headlines blaming private credit for failures like First Brands, the vast majority (over 95%) of the exposure lies with banks and in the liquid credit markets. This narrative overlooks the structural advantages and deeper diligence inherent in private deals.

The greatest systemic threat from the booming private credit market isn't excessive leverage but its heavy concentration in technology companies. A significant drop in tech enterprise value multiples could trigger a widespread event, as tech constitutes roughly half of private credit portfolios.
