Pimco Warns of Systemic 'Bad Underwriting' Crisis in Private Credit Markets

Pimco, one of the world’s largest fixed-income managers, has identified a systemic deterioration in underwriting quality across the private credit sector, warning of a looming crisis. The firm highlights a surge in loans issued with weak covenants, overstated borrower cash flows, and excessive leverage—factors that could lead to a material increase in default rates over the next 18 to 24 months. According to internal analyses, the share of privately placed leveraged loans with below-investment-grade credit metrics has risen to 32% in 2025, up from 21% in 2023. This deterioration is occurring amid a broader environment of rising interest rates and tighter financial conditions, which are straining borrowers’ ability to service debt. Pimco notes that nearly 45% of current private credit deals include covenant-lite structures, which offer minimal borrower protections. This contrasts sharply with pre-2020 standards, when such structures were rare. The firm estimates that if default rates in private credit rise to 8%—a level seen during the 2020 pandemic—total losses could exceed $120 billion across the sector. Market indicators reflect growing concern: the ICE BofA US High Yield Index (HYG) has seen its credit spread widen by 130 basis points since late 2024, while the Bloomberg Barclays U.S. Corporate High Yield Index (LQD) has posted negative returns in three of the last four quarters. The CBOE Volatility Index (^VIX) has averaged 22.4 since January 2025, signaling elevated investor anxiety. Oil prices (CL=F) have also declined 11% in the past six months, pressuring energy-sector borrowers reliant on private credit. Investors in leveraged loan funds, corporate bondholders, and financial institutions with exposure to private credit face heightened risk. Pimco recommends a selective approach to private credit allocation, favoring deals with strong collateral, conservative leverage ratios, and robust cash flow coverage. The firm also urges regulators and credit rating agencies to re-evaluate standards for private credit disclosures and risk assessments.
