Years of low interest rates encouraged risk-taking, resulting in a large pool of low-rated loans (B3/B-). Now, sustained higher rates are stressing these weak capital structures, creating a boom in distressed debt opportunities even as the broader economy performs well.

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 gap between single-B and riskier triple-C rated loans has widened to double its 10-year average. This high dispersion, driven by sector-specific fears and LME-related technicals, separates skilled from unskilled CLO managers. It creates an environment where proactive risk management and credit selection are paramount.

Private equity giants like Blackstone, Apollo, and KKR are marking the same distressed private loan at widely different values (82, 70, and 91 cents on the dollar). This lack of a unified mark-to-market standard obscures true risk levels, echoing the opaque conditions that preceded the 2008 subprime crisis.

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.

The high-yield bond market is now nearly 60% BB-rated, a significant quality improvement over the last decade. Risk has instead concentrated in the lower-quality, B-rated leveraged loan and direct lending markets, making high-yield spreads an unreliable gauge of overall credit stress.

Despite strong current performance driven by technicals, the real risk for leveraged loan issuers is their ability to refinance in 2-3 years. This looming "refinancing wall" could force many companies back into the high-yield market, creating a new wave of opportunities for credit investors.

The traditional two-tier credit market (investment grade and high-yield) has evolved. A new four-tier hierarchy of credit quality now exists: Investment Grade, High Yield, Leveraged Loans, and finally, Private Credit, which has absorbed the riskiest deals that cannot find financing in the other markets.
