What Is Private Credit?

A plain definition

Private credit is lending done outside the public bond market and outside the regulated banking system. Instead of a borrower issuing a bond that trades on an exchange, or drawing a loan from a commercial bank, the borrower negotiates directly with a non-bank lender — usually an investment fund — that holds the loan to maturity. The terms are private, the loan is illiquid, and the lender earns a yield premium for accepting that illiquidity and for doing the credit work in-house.

The borrowers are mostly mid-sized companies: businesses too large for a regional bank line, too small or too leveraged for the investment-grade bond market, and often owned by a private-equity sponsor that wants flexible, bespoke financing for an acquisition or refinancing. The lenders are asset managers — names such as Ares, Blackstone, Apollo, KKR, Sixth Street, HPS, Golub, and Owl Rock — who pool capital from pension plans, insurance companies, endowments, sovereign wealth funds, and, increasingly, individual investors through interval funds and business development companies (BDCs).

Why it has grown so quickly

The asset class barely existed in its current form before the global financial crisis. It is now estimated by the IMF and BIS to be a roughly $2 trillion market — comparable in size to the US high-yield bond market and the US leveraged loan market. Three forces explain the growth.

Bank retreat. Post-2008 regulation — Basel III capital rules, the Volcker Rule, and the leveraged-lending guidance issued by US regulators in 2013 — made it more expensive for banks to hold middle-market and leveraged loans on their balance sheets. Capital that banks pulled back was filled in by funds that face no equivalent capital charge, because their investors accept lock-ups and direct loss exposure.

Investor demand for yield. A decade of near-zero policy rates pushed institutional allocators to look for income wherever they could find it. Private credit offered floating-rate coupons, senior positions in the capital structure, and yields several hundred basis points above comparable public debt. As rates rose in 2022–2024, those floating-rate coupons repriced upward, making the asset class more attractive still.

Private-equity plumbing. Buyout sponsors prefer to negotiate one loan with one or two lenders rather than syndicate a deal through a bank. Private credit funds can move faster, hold the entire loan, and quietly restructure terms when a portfolio company hits a rough patch. As the PE industry has scaled, the lending market that finances it has scaled with it.

How it differs from a bank loan or a bond

A bank loan sits on a regulated balance sheet funded by deposits; a bond trades publicly and is priced minute to minute. A private credit loan sits inside a closed-end fund, is marked to model rather than to market, and may never trade after origination. That structural difference shapes everything else — the yield, the covenants, the workout dynamics, and the systemic risk profile.

The covenants are typically tighter than those in the broadly syndicated loan market, because the lender keeps the paper. The documentation is bespoke. Recovery in default tends to be higher than in public high-yield, partly because the lender group is small and aligned. And because the loans are illiquid, end-investors cannot redeem on demand — most private credit vehicles use multi-year lock-ups or quarterly redemption gates.

Common fund types

Private credit is an umbrella term covering several distinct strategies. The main ones an allocator will encounter:

• Direct lending. Senior secured loans to middle-market companies, usually first-lien, floating-rate, and held to maturity. This is the largest and most plain-vanilla slice of the market, and the one most BDCs concentrate on.
• Mezzanine and junior debt. Subordinated loans, second-lien debt, and preferred equity that sit below the senior lender in the capital structure. Higher yield, higher loss-given-default, often used to bridge an equity gap in a buyout.
• Distressed and special-situations debt. Buying the debt of stressed or defaulted companies at a discount, with the goal of restructuring the business or controlling the workout. Closer to private equity in workload and return profile.
• Asset-based lending. Loans secured by specific collateral — receivables, inventory, equipment, aircraft, royalties, or consumer loan pools. Increasingly the growth frontier of the asset class as direct lending crowds.
• Venture debt. Loans to venture-backed companies, typically alongside or shortly after an equity round. Smaller market, higher correlation with the venture cycle.
• Real estate and infrastructure debt. Loans secured by commercial property or infrastructure assets. Treated as a separate allocation by many institutions but mechanically part of the same private-credit universe.

What to watch

The asset class has never been tested through a full default cycle at its current scale. Regulators — the Fed, the Bank of England, the ECB, and the IMF — have all flagged questions about valuation discipline, leverage at the fund level, interconnections with the banking system through warehouse lines, and the rapid growth of retail-facing vehicles. None of those concerns are reasons to dismiss the asset class; all of them are reasons to read the next downturn carefully.

For the working investor or the curious reader, the useful takeaway is that private credit is no longer a niche. It is now a structural part of how mid-sized companies are financed in the United States and Europe, and a growing share of how pension and insurance balance sheets are invested. Following it has become part of following finance.
