In October, Jamie Dimon offered a warning that rattled corners of Wall Street. "When you see one cockroach, there are probably more," the JPMorgan Chase CEO observed, referring to a sudden string of defaults among companies backed by private credit lenders. A month later, billionaire bond investor Jeffrey Gundlach was more direct: private lenders, he said, were making "garbage loans," and the next financial crisis would likely emerge from their ranks.

The warnings come as private credit—a catch-all term for non-bank lending to companies—has grown into one of the most consequential and least understood corners of the financial system. Assets under management have exploded from approximately $1 trillion a decade ago to more than $2 trillion today, with projections reaching $4 trillion by 2030. The question haunting markets: Is this sustainable growth or a bubble inflating toward disaster?

What Private Credit Actually Is

Private credit emerged to fill a gap left when banks retreated from certain lending activities after the 2008 financial crisis. Stricter regulations made it less attractive for traditional banks to lend to mid-sized companies, private equity buyouts, and other situations deemed too risky or complex. Private credit funds—backed by pension funds, insurance companies, endowments, and increasingly retail investors—stepped in.

The appeal was straightforward: these loans offered higher yields than traditional bonds, typically 8-12% annually compared to 5-7% for investment-grade corporate debt. For institutions struggling to meet return targets in a low-rate environment, private credit became essential.

Key characteristics of the market:

  • Direct lending: Loans made directly to companies without bank intermediation
  • Limited liquidity: Investors typically can't easily sell their positions
  • Opaque pricing: Without public markets, valuations are often estimates
  • Fewer protections: Unlike publicly traded debt, private loans often lack covenants that protect lenders

The Defaults That Spooked Markets

Last fall, a string of American companies backed by private credit collapsed in quick succession, validating the cockroach analogy. The sudden failures shared common threads: aggressive financial engineering, weakening business fundamentals, and loan structures that gave companies excessive flexibility to delay problems rather than address them.

The defaults thrust private credit into an uncomfortable spotlight. For years, proponents had argued that the asset class was fundamentally safer than traditional leveraged lending because private lenders could work more closely with borrowers to avoid defaults. The autumn wave of failures challenged that narrative.

"Looking below the surface of private credit reveals a market vulnerable to economic shocks. We're seeing it tested through a full credit cycle for the first time, and the results aren't reassuring."

— Credit analyst at Moody's Ratings

The Safeguards Are Disappearing

Perhaps more concerning than individual defaults is a broader trend: private credit firms are increasingly dropping the protections that traditionally distinguished their loans from riskier leveraged lending.

Covenants—contractual provisions that restrict borrower behavior and trigger warnings when financial health deteriorates—were once a hallmark of private credit. They gave lenders early warning of trouble and leverage to force corrective action. Increasingly, competitive pressure has led private credit funds to abandon these safeguards.

According to recent industry data:

  • Covenant-lite loans: Now represent over 60% of new private credit issuance, up from under 20% five years ago
  • Payment-in-kind provisions: Arrangements allowing borrowers to defer cash payments are increasingly common
  • Borrower-friendly amendments: Existing loans are being modified to remove protections that were originally negotiated
  • Leverage tolerance: Average debt-to-EBITDA ratios in new deals have climbed above 6x, historically considered aggressive

The erosion reflects brutal competition. With hundreds of billions in capital chasing deals, borrowers can demand—and receive—increasingly favorable terms. Private credit firms face a choice: accept weaker protections or lose deals to competitors who will.

Where the Money Keeps Flowing

Despite the warnings, capital continues pouring into private credit at a remarkable pace. TPG closed more than $6 billion for its third flagship Credit Solutions fund in December. Neuberger Berman recently announced its fifth private debt fund at $7.3 billion. Semi-liquid vehicles targeting wealthy individuals—a relatively new channel—now command nearly a third of the $1 trillion direct lending market.

The persistence of inflows reflects several factors:

  • Yield hunger: With public bond yields compressed, investors still crave higher returns
  • Institutional commitments: Pension funds and insurers have made private credit a "core allocation" and are slow to reverse course
  • Track record (so far): Despite recent defaults, overall loss rates remain manageable
  • Fee structures: Private credit is highly profitable for fund managers, creating incentives to raise ever-larger funds

The Retail Investor Risk

One development particularly concerns regulators: the rapid expansion of private credit access to individual investors. Historically, these markets were limited to institutional investors and the ultra-wealthy. New fund structures have opened the door to anyone with $25,000 or more to invest.

The pitch is seductive: earn 9-11% yields in a diversified portfolio of corporate loans. The risks are less emphasized: limited ability to withdraw capital, opaque valuations that may not reflect true conditions, and exposure to credit losses that could be substantial in a recession.

Retail participation in private credit grew from virtually nothing in 2019 to an estimated $150 billion today. If economic conditions deteriorate and these investors discover they can't access their money when they need it, the consequences could extend beyond financial markets.

The 2026 Test Case

Several factors make 2026 particularly consequential for private credit:

  • Maturity wall: A significant volume of private credit loans originated during the easy-money years of 2020-2022 come due this year and next
  • Refinancing risk: Companies that borrowed at low rates face refinancing at higher costs
  • Economic uncertainty: Trade tensions, potential recession, and policy volatility create headwinds for borrowers
  • Rate environment: With the Fed holding rates elevated, the "extend and pretend" strategy has limits

Industry participants are paying close attention to default rates, which have crept up but remain manageable at approximately 3-4%. Historical comparisons are difficult because private credit at this scale hasn't existed through a full economic cycle. The 2008 crisis predated the market's emergence; the 2020 pandemic was too brief to truly stress loans backed by long-term capital.

What Prudent Investors Should Consider

For individuals with exposure to private credit—whether through direct investments, retirement plans, or funds that include the asset class—several considerations apply:

  • Understand your exposure: Many target-date funds and balanced portfolios now include private credit allocations
  • Assess liquidity needs: Private credit investments typically can't be quickly converted to cash
  • Evaluate manager quality: The difference between top-quartile and bottom-quartile private credit managers is substantial
  • Consider economic scenarios: How would your portfolio perform if private credit losses exceeded expectations?

Private credit may well navigate the current environment without major incident. The industry's defenders note that losses remain contained, defaults are being worked out, and capital structures are generally sound. But the warnings from sophisticated investors like Dimon and Gundlach deserve attention. The cockroaches are visible now. Whether more are hiding in the walls is the multi-trillion-dollar question hanging over Wall Street in 2026.
