CLOs Under Scrutiny: Could Private Credit End the Goldilocks Bull Market?
The private credit boom has become one of the most fascinating—and potentially dangerous—developments in global finance. As investors keep chasing yield while central banks maintain relatively stable policy, the world of non-bank lending has exploded. With assets nearing $2 trillion globally, private credit funds have stepped in where traditional banks retreated, lending to middle-market companies, leveraged buyouts, and even distressed borrowers.

At first glance, it looks like a “Goldilocks” moment—rates aren’t too high, defaults remain contained, and investors are rewarded with juicy floating-rate yields. Funds such as those managed by Blackstone, Carlyle Group, and Golub Capital dominate this field, managing tens of billions in Collateralized Loan Obligations (CLOs). These instruments bundle corporate loans into structured products, sliced by risk, and sold to investors looking for yield without the volatility of equities. The senior tranches often look safe on paper, paying steady coupons backed by hundreds of underlying loans. (Moody’s)
However, beneath this seemingly calm surface lies a growing fragility. The rapid expansion of private credit has outpaced nearly every other form of lending since 2016. According to Moody’s, loans to private credit providers have surged to nearly $300 billion—almost triple what they were a decade ago. This growth is not necessarily bad, but it brings opacity and interconnectedness that regulators are struggling to monitor. The problem is that most of this market operates outside the traditional banking system, where transparency and capital requirements are much stricter.
CLOs built on private credit loans may also hide more risk than investors realize. Although default rates have declined from 5.6 % in 2024 to around 2.6 % in 2025, according to Deutsche Bank Research, the market remains vulnerable to shifts in refinancing conditions. Many companies in these portfolios are non-investment grade borrowers, often owned by private equity firms. Their balance sheets are highly leveraged, and if growth slows or interest coverage weakens, a wave of restructurings could follow.

Interestingly, the private credit default rate—currently around 1.84 % per the Proskauer Private Credit Index—remains relatively low, but stress is building beneath the surface. More companies are using “payment-in-kind” facilities, which allow them to pay interest by issuing more debt rather than using cash. It’s a clever accounting trick that delays defaults but doesn’t solve solvency problems. Traders familiar with structured credit know this dynamic well—it’s the calm before the storm.
The refinancing wave expected in 2026–2027 could be the true test. Many private loans were issued during ultra-low-rate years and will soon mature. If base rates remain elevated or spreads widen, refinancing will become expensive or even impossible for weaker issuers. CLO managers might rotate portfolios aggressively to maintain yield, but liquidity could vanish quickly in a downturn. As MarketWatch noted, this lightly regulated, opaque corner of Wall Street could be where the next systemic shock originates.
Even though Blackstone and Carlyle appear financially robust - each holding over \$40 billion in total assets—the health of the borrowers behind their CLOs matters far more than the sponsors’ size. If defaults creep higher, junior CLO tranches could be wiped out quickly, potentially triggering cross-market contagion. Jamie Dimon of JPMorgan recently warned that the sheer scale of the private credit industry, now exceeding $2 trillion, could amplify financial stress during a downturn. (Investopedia)
For traders and investors, the implications are clear. The risk-reward balance in private credit is still attractive, but complacency is dangerous. Structured credit vehicles like CLOs can deliver stable income in calm markets but behave unpredictably when liquidity dries up. The current environment may feel “just right,” but the combination of weaker covenants, opaque valuations, and growing leverage could turn a Goldilocks bull market into a Minsky-style unwind.
As the Financial News London put it, regulators should be wary: “the danger is not in what we see—it’s in what we don’t.”
In short, private credit has reshaped modern finance, offering yield and flexibility where traditional channels faltered. Yet, traders should remember: markets that look too calm are often the ones most vulnerable to shocks. The Goldilocks narrative may still hold for now—but under the surface, the porridge is quietly getting hotter.
