Most writing about private credit risk is produced by people who manage private credit. That does not make it dishonest, and it does mean the risks tend to appear as considerations to be managed rather than as things that could go substantially wrong.
This page takes the other approach. The strategy has real merits, covered elsewhere in this cluster. What follows is what an investor is actually exposed to.
Credit loss, which is the point
Private credit is lending. The primary risk is that borrowers do not repay.
The mitigations are genuine: most direct lending is senior secured, which improves recovery prospects, and covenants can give lenders earlier intervention rights than a bond indenture would. Recovery on a first-lien secured loan is generally better than on unsecured debt.
The offsetting facts are equally real:
Borrowers are smaller and more levered. Middle market companies have less financial cushion, less diversified revenue, and fewer options in difficulty than large-cap issuers. Higher recovery on a defaulted loan does not help if the default rate is also higher.
Sponsor-backed does not mean supported. Much direct lending is to private-equity-owned companies, and the presence of a sponsor is often cited as a credit positive. A sponsor may inject capital to protect its equity — and will not if the equity is already worthless. The support is conditional on the sponsor still having something to protect.
Documentation has loosened. Covenant protections in parts of the market have weakened over time as capital competed for deals. Whether a given loan has meaningful covenants is a fact about that loan, not about the asset class.
Valuation, which is where problems hide
Loans do not trade. NAV is the output of a fair value process — models, comparables, and judgment — rather than an observed price.
Three consequences follow.
The valuer has an interest. Marks influence reported performance and fees. Independent valuation input, auditor review, and board oversight constrain this, and they do not eliminate the fact that judgment is being exercised by someone who benefits from the outcome.
Marks lag reality. A deteriorating borrower may be held at or near par for some time before the mark moves. This is not necessarily improper — valuation policies require evidence, and evidence accumulates slowly — but it means reported stability can precede recognised problems.
Smooth reporting is a measurement artefact. Private credit reports lower volatility than traded credit. That comparison is between a periodic appraisal-based process and a continuous market, not between two risk profiles. Smoothed series feed into portfolio construction models and mechanically inflate the apparent case for the allocation. See private credit vs. high yield.
The practical signal to watch is non-accrual trend, which is disclosed by BDCs and is harder to manage than a mark.
Leverage at the fund level
The loans are one layer. Many funds borrow against the loan book, which is another.
Fund-level leverage magnifies both returns and losses. A modest impairment in an unlevered book becomes a substantial one in a levered fund. Registered vehicles including BDCs face statutory limits; private funds are bounded only by their documents and their lenders.
The more specific concern is the lender. A credit facility comes with covenants and borrowing base tests. If asset values decline, a facility can require repayment or additional collateral at precisely the moment the fund is least able to provide either — forcing sales into a weak market. This is how a credit problem becomes a liquidity problem, and it is a mechanism that operates independently of how good the underlying underwriting was.
PIK, and income that is not cash
Payment-in-kind interest accrues rather than being paid in cash. It has legitimate uses, particularly for growing borrowers.
It also allows a fund to report income it has not received. A portfolio with rising PIK can show healthy net investment income and pay distributions while cash generation deteriorates. The distributions must then come from somewhere else — borrowings, return of capital, or new subscriptions.
PIK share of total income, and its trend, is one of the more informative disclosures available and one of the less examined.
Liquidity mismatch
Loans mature over years. Many vehicles offering access to private credit — interval funds, perpetual BDCs — offer periodic repurchases.
The mismatch is managed through liquid sleeves, credit facilities, portfolio cash flow, and new subscriptions. In ordinary conditions it works.
The dependence on new subscriptions deserves attention, because it fails in the specific scenario it needs to survive: inflows stop under the same conditions that generate redemptions. A vehicle whose liquidity relies materially on new money is more fragile than its stated repurchase cap implies. See semi-liquid fund repurchase mechanics.
Investors should expect gates and proration to bind under stress. That is the structure working as designed, and it is still an outcome to plan for.
Concentration and correlation
Portfolios can be concentrated by borrower, by sector, and — less visibly — by private equity sponsor. A fund lending to many companies owned by a small number of sponsors has correlated exposure that a borrower-level concentration table will not show.
Sector concentration matters too, particularly where a fund is heavily exposed to businesses whose economics depend on a single variable.
The rate story cuts both ways
Direct lending is predominantly floating rate, which is presented as protection against rising rates. For the lender’s income, it is.
For the borrower it is the opposite: rising rates raise debt service on a levered company that may have been underwritten assuming lower costs. Rising rates improve the coupon and simultaneously worsen the credit paying it. Debt service coverage at current rates rather than at underwriting rates is the number that matters.
The untested cycle
The asset class expanded substantially after 2008, in a period characterised by low rates, abundant capital, and no prolonged severe default cycle in this market at its current scale.
This is a statement about the evidence base, not a prediction. Much of the current market has not operated through a severe downturn in its present size and structure. Track records may be long in years without covering the conditions that matter most.
Several features would only be tested in such a cycle: how marks behave when many borrowers deteriorate at once, whether repurchase mechanisms hold under sustained pressure, how fund-level leverage providers behave, and whether the workout capabilities managers describe exist at scale when many loans need them simultaneously.
What to actually examine
- Non-accrual trend over several periods, not a point reading
- PIK as a share of income, and its direction
- Net investment income versus the distribution — a persistent gap is among the most reliable warning signs available
- Fund leverage and the terms of the facility, including covenants
- Valuation governance — who values, with what independent input
- Concentration by borrower, sector, and sponsor
- Seniority mix — how much is genuinely first-lien
- Covenant profile across the book
- Liquidity sources, and whether repurchases have depended on new subscriptions
- Manager history through 2008 — did these people run credit then, and what happened
The fair conclusion
Private credit is a legitimate strategy with structural features that genuinely favour lenders: seniority, security, covenants, and direct negotiation. Investors are compensated for illiquidity and complexity, and much of that compensation is real.
The risks are also real, and the most important one is not any single item above. It is that the reporting is smooth, the valuations are internal, and the structure is untested at scale — which together mean an investor may not know a problem exists until it is well advanced.
This guide is educational and general; it is not investment advice. Fund terms and portfolio characteristics vary materially; review the specific disclosures and filings.
Frequently Asked Questions
What are the main risks in private credit?
Credit losses on the underlying loans, valuation uncertainty since most holdings do not trade, leverage at the fund level amplifying losses, borrower concentration in smaller companies, payment-in-kind income accruing without cash, liquidity mismatch between fund terms and asset realisability, and the fact that much of the current market has not been tested through a severe default cycle.
Is private credit riskier than high yield bonds?
Different rather than uniformly riskier. Private credit is typically more senior and more secured, which improves recovery prospects, and typically lends to smaller and more leveraged borrowers, which raises default probability. It is also illiquid and valued rather than priced. The comparison depends on which dimension matters to the investor.
Why is valuation a risk in private credit?
Because loans do not trade, values are produced by a fair value process using models and judgment rather than observed prices. Marks are influenced by a party with an interest in them, they respond more slowly than markets, and a portfolio can appear stable while underlying credit quality deteriorates.
What is the concern about PIK income?
Payment-in-kind interest accrues without cash changing hands. It can support reported income and distributions without producing the cash to pay them, and a rising share of PIK across a portfolio can indicate borrowers being accommodated rather than performing.
Has private credit been tested in a downturn?
Parts of it have. The asset class expanded substantially after the 2008 financial crisis, so much of the current market in its present size and form has not experienced a severe, prolonged default cycle. That does not mean it will perform badly; it means the evidence base is thinner than the length of the track records suggests.
