For the past five years, private credit has been the most celebrated asset class on Wall Street. It promised higher yields than public bonds, lower volatility than equities, and the kind of steady, predictable returns that pension funds, endowments, and insurance companies had been starving for in a world of compressed credit spreads. The money poured in. By late 2025, private credit represented approximately $1.2 trillion in committed capital across global markets. It now funds 80% of all leveraged buyouts, up from less than 30% a decade ago. And the industry's headline default rate, sitting stubbornly below 2% for several years, seemed to validate every optimistic assumption.
Then the cockroaches started appearing.
The Headline Rate Versus the Real Rate
The most important number in private credit is also the most misleading. The sub-2% headline default rate that fund managers cite in their marketing materials counts only outright payment defaults, borrowers that miss a scheduled interest or principal payment. It does not count the growing universe of "selective defaults" and "liability management exercises" that have become the industry's preferred method of dealing with troubled borrowers.
A selective default occurs when a borrower renegotiates terms with its lender in ways that technically avoid a formal default but result in economic losses for the lender. These exercises can include extending maturities, converting cash interest payments to payment-in-kind (PIK) interest that accrues but is not actually paid, reducing loan balances in exchange for equity stakes, or creating new priority tranches that subordinate existing lenders.
When these selective defaults and liability management exercises are included in the calculation, the "true" default rate in private credit approaches 5%. That is a meaningfully different picture than the one being presented to investors who allocated capital based on the headline figure.
The Cockroach Analogy
JPMorgan CEO Jamie Dimon has been among the most prominent voices raising alarms. His metaphor has become the shorthand for the industry's vulnerability: "When you find one cockroach, more are likely nearby." Dimon was referencing a series of high-profile bankruptcies in late 2025, including Tricolor and First Brands, that exposed the fragility of certain private credit structures. In each case, the deterioration had been visible in the company's financials for quarters before the formal default, but the flexible reporting requirements of private credit meant that investors had limited visibility into the unraveling.
DoubleLine Capital's Jeffrey Gundlach has gone further, calling private credit the "top candidate to start the next financial crisis." His argument centers not on the absolute level of defaults but on the interaction between private credit and the broader financial system. Private credit vehicles often rely on bank credit facilities for leverage and liquidity. In a stressed environment, those vehicles may draw on their bank lines at precisely the moment that banks are tightening credit elsewhere, creating a procyclical dynamic that amplifies rather than absorbs financial shocks.
The Structural Vulnerabilities
Private credit's rapid growth has introduced several structural risks that did not exist when the market was a fraction of its current size.
The first is valuation opacity. Unlike publicly traded bonds, which are marked to market daily, private credit loans are valued using models and estimates that are updated quarterly, if at all. Fund managers have significant discretion in determining the fair value of their holdings, and the incentives run in one direction: higher valuations mean higher reported returns, which attract more capital, which generates more management fees. Multiple studies have found that private credit funds tend to report smoother, less volatile returns than their underlying loan portfolios would suggest, a pattern that looks reassuringly stable until it suddenly does not.
The second vulnerability is liquidity mismatch. Many private credit funds, particularly those marketed to high-net-worth individuals through semi-liquid structures, offer quarterly or monthly redemption features. But the underlying loans are illiquid by nature, with maturities of five to seven years and no active secondary market. If enough investors request redemptions simultaneously, funds face a choice between selling assets at fire-sale prices or suspending redemptions entirely, options that tend to accelerate rather than contain panic.
The third risk is concentration. Private credit has become so large that it now dominates certain segments of the lending market. In the leveraged buyout space, private credit funds are not just the marginal lender but frequently the only lender. When a single fund or a small group of funds holds the entire capital structure of a borrower, the traditional diversification benefits of credit investing disappear. A single large default can have an outsized impact on fund-level returns.
The Late-Cycle Signal
Corporate credit is beginning to display the telltale signs of late-cycle behavior. Lending standards have loosened progressively over the past three years, with borrowers securing lower spreads, weaker covenants, and higher leverage multiples than would have been available in a tighter market. The average debt-to-EBITDA ratio for private credit-funded buyouts has crept above 6.5 times, a level that historically correlates with elevated default rates two to three years later.
The macroeconomic backdrop is not helping. GDP growth printed at just 1.4% in the fourth quarter, well below expectations. The Federal Reserve has paused its rate-cutting cycle with the fed funds rate at 3.5-3.75%, and several officials have indicated that rate hikes could return to the table if inflation does not continue declining. For leveraged borrowers with floating-rate debt, the interest rate environment remains challenging even after the cuts delivered in late 2025.
Why It Matters for Ordinary Investors
Private credit may sound like a niche corner of institutional finance, but its tentacles now reach into virtually every corner of the investment landscape. Pension funds that manage the retirement savings of teachers, firefighters, and public employees have allocated aggressively to private credit in search of yield. Insurance companies have shifted billions from public bonds into private loans. And a growing number of wealth management platforms now offer private credit funds to individual investors with minimums as low as $25,000.
The appeal is obvious. In a world where the 10-year Treasury yields roughly 4.1% and investment-grade corporate bonds offer only modestly more, private credit's promise of 8-12% returns looks irresistible. But those returns come with risks that are genuinely difficult to assess: illiquidity, valuation uncertainty, concentrated exposure, and the possibility that the smooth return profile that attracted investors in the first place was an artifact of favorable market conditions rather than a permanent feature of the asset class.
None of this means that private credit is destined for a crisis. The industry's largest players, firms like Apollo, Ares, Blackstone, and Blue Owl, have deep experience, sophisticated risk management capabilities, and the scale to absorb losses without existential consequences. But the industry has never been tested at its current size, and the economic conditions that allowed it to grow so rapidly, including low defaults, abundant liquidity, and a steadily expanding economy, are giving way to something more challenging.
Jamie Dimon's cockroach warning was not a prediction of catastrophe. It was a reminder that in credit markets, the first sign of trouble is almost never the last. For investors with private credit exposure, the prudent response is not to panic but to demand transparency: ask for true default rates rather than headline figures, understand the liquidity terms of your fund, and make sure the yield you are earning compensates for the risks you are taking. In private credit, as in pest control, the time to act is before the infestation spreads.
