Private Credit Risk in the Post-Boom Era: Systemic Undercurrents and Early Warning Signals

---

The private credit sector, now a $1.7 trillion industry, has emerged as a cornerstone of modern capital markets, driven by post-2008 regulatory constraints on traditional banks and a surge in demand for non-bank financing, according to FDIC's risk review. However, this rapid expansion has sown the seeds of systemic risk, with interconnectedness, opaque valuations, and fragile borrower profiles creating undercurrents of instability. As the sector edges closer to $3 trillion in assets under management by 2028, S&P Global Market Intelligence warns of rising defaults; investors and regulators must grapple with early warning signals that suggest a potential reckoning.

Systemic Undercurrents: Interconnectedness and Opacity

One of the most pressing concerns lies in the sector's growing entanglement with traditional financial institutions. Banks now provide critical services to private credit funds, including capital call facilities, joint lending arrangements, and credit risk transfers, a point highlighted in the FDIC review. For instance, U.S. systemically important banks like JPMorgan Chase and Citigroup hold over $1 trillion in loans to nonbank financial institutions (NBFIs), including private credit funds, the FDIC review notes. This interconnectedness, however, is often shrouded in opacity. Data on deposits from private credit funds within banks remains largely unavailable, creating blind spots in liquidity risk assessments, as the FDIC review emphasizes.

The structural opacity of private credit assets further exacerbates systemic vulnerabilities. Unlike public securities, private credit loans are illiquid and infrequently appraised, leading to stale valuations that can trigger sudden repricing during market stress, the FDIC review warns. This was starkly illustrated in March 2025, when Ares Capital faced a 15% drop in net asset value (NAV) and was forced to sell $2.4 billion in assets to meet redemption requests during a rate spike, an episode discussed in the FDIC review. Such events highlight the fragility of liquidity promises in a sector where covenant-lite structures and payment-in-kind (PIK) interest mechanisms mask underlying distress, as the FDIC review documents.

Early Warning Signals: Leverage, PIK, and Selective Defaults

The private credit sector's risk profile is increasingly defined by early warning signals. Payment-in-kind (PIK) interest, where borrowers defer interest payments, has surged as a liquidity management tool. In 2024, 27% of monitored borrowers had interest coverage ratios below 1.0, while leverage ratios-though slightly reduced from 6.3x in 2023 to 5.9x-remain dangerously high, according to the FDIC review. These trends suggest borrowers are stretching to maintain solvency, a red flag for future defaults.

Selective defaults have also spiked, with 60% of global corporate defaults in 2024 falling into this category, the FDIC review reports. Unlike traditional defaults, selective defaults often involve covenant breaches, PIK toggles, or maturity extensions, which obscure distress and delay corrective actions. This surge is attributed to flexible covenants and amortization holidays in private credit loans, which allow borrowers to delay visible signs of trouble, as noted in the FDIC review. For example, S&P Global Market Intelligence notes that selective defaults outpaced conventional defaults by a 5:1 ratio in 2024, a trend that could amplify contagion risks if underwriting standards continue to erode.

Regulatory Responses and the Path Forward

Regulators are beginning to take notice, as noted by a CFA Institute blog. The Fed's Boston branch has emphasized the need to distinguish between credit substitution (private credit capturing market share from banks) and credit expansion (private credit issuing riskier loans banks would avoid)-a distinction critical to assessing systemic risk, according to the Fed's Boston branch. Meanwhile, the CFA Institute blog reports that the IMF has called for greater transparency in private credit valuations and risk monitoring to prevent a repeat of the 2008 crisis.

However, regulatory oversight remains fragmented. Private credit funds operate with lower direct leverage than banks, which mitigates loss amplification in adverse scenarios, the FDIC review observes. Yet, their interconnectedness with the broader financial system-via bank credit lines and insurance company holdings-creates spillover risks. For instance, many insurance companies hold private credit assets with durations far shorter than their liabilities, creating a mismatch that could destabilize during downturns, the FDIC review cautions.

Conclusion: Balancing Innovation and Stability

The private credit sector's evolution reflects both innovation and hubris. While its ability to provide capital to underserved markets is laudable, the structural weaknesses-opaque valuations, high leverage, and regulatory gaps-pose systemic threats. Investors must weigh the sector's yield appeal against its vulnerability to liquidity shocks and contagion. For regulators, the challenge lies in fostering innovation without compromising financial stability.

As the sector approaches $3 trillion in AUM, the need for robust risk management, enhanced transparency, and proactive oversight has never been greater. The next financial crisis may not erupt in a traditional bank but in the shadowy corners of private credit-a ticking time bomb, as CNBC recently warned.
