Private Credit Is Not Outside the Financial System
This series examines private credit as a connected financing channel: how private funds and business development companies lend to firms, how banks and investors connect to those loans, and how risks can travel through the wider nonbank financial system. The practical question is not whether private credit is simply good or bad. It is who receives the financing, who supplies and funds it, who absorbs losses, and which links can transmit stress. By the end of this series, readers should be able to distinguish those relationships rather than treating every nonbank lender as an isolated substitute for a bank.
A large market built around direct relationships
Private credit is credit originated by nonbanks and negotiated bilaterally between a borrower and a lender. That definition describes a financing relationship, not one legal entity or one investment product. A private-debt fund, a business development company (BDC), and a bank can all participate in a deal, but they do not become the same kind of institution by doing so. Likewise, “private credit” is a broader market category than “direct lending,” one of its most important strategies.
The market is now too large to understand as a niche for specialist investors. The Federal Reserve estimated that, in the second half of 2025, private-credit loans accounted for about $1.4 trillion, or 10 percent, of the debt of U.S. nonfinancial corporations. They represented about one-third of below-investment-grade corporate debt when bank loans were excluded. These are estimates assembled from several commercial and official data sources, not a single audited balance-sheet total, but the scale is still consequential: a financing channel serving riskier companies can influence investment, refinancing, and the supply of credit beyond the funds that originate the loans.
Direct lending grew particularly quickly within that market. Specialized funds negotiate directly with mostly small and mid-sized companies, often offering floating-rate loans with detailed covenants and terms tailored to the borrower. The appeal is partly speed and flexibility. A company may value a lender that can structure a bespoke deal, respond to changing circumstances, or renegotiate within an ongoing relationship. Such borrowers can also be less transparent or more leveraged than the firms best served by conventional bank lending or public bond markets. The lender is therefore being paid to take meaningful credit risk, not merely to provide a cheaper version of a standardized loan.
The structure also differs from syndicated public-market credit. A private lender generally keeps a direct loan on its balance sheet until maturity rather than arranging a large group of lenders and relying on an active secondary market. That can support closer monitoring and reduce the pressure to sell into a volatile market. It can also make the asset harder to value or liquidate when conditions change. A relationship that is valuable in ordinary times can become a constraint when many investors, lenders, or borrowers need to adjust at once.
The network behind a “nonbank” loan
The word nonbank can create the wrong mental picture. It suggests that a loan has moved from a bank into a separate compartment. In practice, private credit is connected to several layers of finance. Investors provide capital to funds or BDCs. Those vehicles lend to companies. Banks may provide a revolving credit line, join a club deal, or extend credit to the private-credit vehicle itself. Other nonbank financial institutions may share assets, provide funding, or hold related exposures. Public credit markets remain an alternative for some borrowers. The boundaries are institutional, but the cash flows and risks can cross them.
A BDC makes this network easier to observe. BDCs are U.S. private-credit intermediaries that typically lend to small and mid-sized firms. Unlike much of the private-credit universe, they disclose their holdings loan by loan each quarter. That does not make them representative of every fund in every respect, but it gives researchers a visible window into exposures that are otherwise difficult to map. The distinction matters: an observable slice can reveal a mechanism without proving that the entire market has the same portfolio, leverage, or funding structure.
Banks can also be inside a private-credit transaction without being the main term lender. The supplied loan-level evidence finds that club deals involving multiple lenders had risen to about 40 percent of secured and unsecured deals by late 2024. Revolvers—credit lines that a borrower can draw and repay—were more common when a deal was a club deal, especially when at least one bank participated. The researchers infer that banks may increasingly provide credit lines while private lenders supply term financing, although the data do not directly establish the causal role of each participant. This is cooperation and interdependence at the same time.
The bank connection is larger than individual deals. The Federal Reserve reported $2.6 trillion in bank credit commitments to other financial entities in the fourth quarter of 2025. Private equity, BDCs, and other private-credit vehicles formed the largest category in its classification of bank lending to nonbank financial institutions. The figure is not a measure of private-credit losses: commitments are not the same as drawn loans, and drawn loans are not the same as realized losses. It does show why a fund’s balance sheet cannot be the only place analysts look for exposure.
The measured map can change as well. After incorporating information from additional data vendors, the Federal Reserve revised estimated commitments to private equity, BDCs, and private credit upward by $261 billion for the fourth quarter of 2025. The revision did not mean that a new set of contracts had suddenly been signed. It meant that some funds previously placed in other categories were recognized differently. In financial stability work, classification is not a cosmetic detail: it affects what appears connected and how large a connection seems.
The diagram is deliberately a map of possible links, not a claim that every deal contains every actor. Its point is that “private” describes how a loan is negotiated and held, while the financing network around that loan may include institutions with different funding promises and regulatory constraints.
The real question is where risk goes
Private credit can solve real financing problems. A flexible lender may fund a company that lacks the scale, transparency, or collateral to access a public market. A fund that holds a loan to maturity may have more reason to monitor the borrower than a trader who expects to sell it quickly. Covenants, seniority, and collateral can give lenders information, control, or recovery rights. These are economic functions, not marketing claims, and they help explain why borrowers and investors have supported the market’s growth.
But each advantage shifts a different risk rather than erasing risk. A bespoke loan may be harder for outsiders to compare. A held-to-maturity asset may be illiquid. A covenant can give a lender an early response without preventing a business model from deteriorating. Collateral can improve recovery while making credit supply more sensitive to property prices. A bank revolver can make a borrower’s financing more resilient while giving the bank a contingent exposure. A BDC can broaden access to private-credit investments while creating a promise that investors may try to redeem against loans that cannot be sold quickly.
That last trade-off has become more important as private credit has reached individual investors. Traditional private-debt funds commonly lock capital for seven to ten years. Newer semi-liquid vehicles offer periodic redemption rights. In the Federal Reserve’s estimates, perpetual-life BDCs and interval funds together held $425 billion in gross assets and $241 billion in net assets in 2025, about one-fifth of private-credit vehicles’ net assets. Their liquidity tools—new inflows, loan repayments, bank lines, and holdings of more-liquid assets—can absorb ordinary requests. They do not turn the underlying loans into daily-liquidity assets.
The same distinction applies to performance data. A portfolio can show low delinquencies and stable valuations while still carrying a concentrated future exposure. A borrower can owe several lenders at once. A sector can look attractive because its historical cash flows were strong while its future economics are being changed by technology. A fund can have low leverage while remaining linked to banks through commitments or to other funds through common borrowers. And the least visible part of the market may be the part for which concentration and counterparty data are weakest.
The broader nonbank system makes the stakes clearer, but it must be used carefully. Research on sovereigns, banks, and NBFIs describes how leverage, collateral, short-term funding, margin calls, and fire sales can create feedback loops. That work is not a direct study of U.S. private-credit funds or BDCs. Its value here is narrower: it shows why moving an activity into a nonbank institution does not automatically contain its consequences. The mechanism depends on the actual links—who funds whom, who holds the same asset, who must meet a redemption or margin call, and who can reduce lending when conditions worsen.
So the central question for this series is not whether private credit is replacing banks. It is how the financial system is being rewired around private loans. The next step is to look closely at the loan and funding structures themselves: who supplies the capital, how a direct loan persists through time, and what happens when investors are offered access to an asset that may be difficult to sell.
