A nearly $3 trillion lending market operates almost entirely behind closed doors in the conference rooms of midtown Manhattan and the more subdued offices of private equity firms in Chicago and Dallas. Exchange tickers, quarterly reports that regular investors can access, and analyst commentary that most people can comprehend are all absent.
The market has more than tripled in size over the last ten years due to the large loans made directly by non-bank lenders to businesses in need of capital and willing to pay for discretion, as well as the returns those loans produce for pension funds, insurance companies, and affluent individuals who have invested in private credit funds. The expansion has been astounding. The supervision hasn’t kept up.
After the 2008 financial crisis, bank regulations tightened, creating a void that private credit fills. Middle-market firms, leveraged buyouts, and enterprises that failed to exceed the risk-weighted asset requirements set by regulators were among the corporate lending categories in which banks withdrew. When non-bank lenders intervened, they found that there were few regulatory restrictions, high demand, and appealing yields.
The information required by a public bond offering is not necessary for these private transactions. Lenders evaluate their own portfolios, establish their own terms, and are largely accountable to their own investors rather than to any external standards. During a decade of low interest rates and favorable credit conditions, that arrangement functioned well. It is currently undergoing more rigorous testing.
Payment in kind, or PIK for short, is the technique that has garnered the most attention. Certain loan arrangements permit a borrower in a private credit agreement to issue more debt in lieu of paying interest in cash. The principal is increased by the interest. It is recorded as income by the lender. Although the loan does not technically default, the company’s actual cash position has not improved. The portfolio appears to be in good shape from the outside.
The number of these so-called shadow defaults has been increasing, and regulators are operating with insufficient knowledge regarding the extent of the activity because the data is not publicly available. The underlying credit quality of private loan portfolios may be significantly worse than reported data indicate, according to the IMF and the Financial Stability Board, who have both specifically highlighted this disparity.
Although linked, the liquidity issue is different. Redeemable windows, which allow investors to withdraw money on a quarterly or semi-annual basis, are usually offered by private credit funds. However, these windows may be closed when a fund’s own liquidity becomes more constrained. Both Cliffwater LLC and Morgan Stanley have put in place “gates,” which prevent investors from withdrawing funds during difficult times.
“Gate” sounds like an administrative term. In actuality, it means that a person who made an investment with the hope of being able to withdraw cannot. That would have regulatory repercussions in a public fund. The majority of private credit is found in the contract conditions that investors accepted, frequently without fully comprehending what doing so would entail in a challenging market.
Observing this market from the outside, it seems like the same discussion keeps coming up but never fully settling. The opacity is acknowledged by regulators. Because private loan portfolios are priced by the lenders themselves rather than by any market transaction, analysts observe the valuation staleness, which makes true portfolio health virtually undetectable until a company defaults and the loss must be recorded.

Stress in private credit does not remain contained within the fund structures that hold these loans because Wall Street’s major institutions are intricately linked to this ecosystem. It spreads. It is still really unclear whether the next credit cycle would show that the private lending boom was based on competent underwriting or on the belief that favorable conditions would persist forever. It’s likely that the solution will come out sooner than most participants anticipate and with less notice than a public market would have.
