Private Credit Funds Explained: How They Work, What They Invest In and What Investors Should Check

How private credit funds work, what they invest in, and the fee, liquidity and valuation terms that decide your real return.

The label on a private-credit fund says little about your outcome. Fee basis, liquidity terms and valuation governance decide your return, and the last one is what most investors forget to check.

Key takeaways

  • The word “private credit” on a fund tells you little. Your outcome is set by the fee basis, the liquidity terms and how the manager values assets that never trade.
  • Vehicle choice dominates. A closed-end drawdown fund locks you in for years; an evergreen fund offers windows that can gate exactly when you want out, as several did across 2025 and 2026.
  • Valuation governance is the most under-checked risk. Because the loans do not trade, the NAV is the manager’s estimate, and a sudden double-digit write-down means the mark was late.
  • This is general information, not financial advice. What suits any one investor depends on their own circumstances and time horizon.

Private credit has stopped being a niche allocation and become a core holding. Global private debt assets under management crossed $2 trillion in 2025 and are forecast to reach $2.64 trillion by 2029 (Preqin), up from roughly $250 billion in 2008. That is a compound growth rate no other private asset class has matched over the same period. When a market grows that fast, the marketing gets ahead of the mechanics, and the word on the fund label starts doing more work than the fund actually does.

So the focus here is the mechanics. If you already grasp what private credit is at a high level, the useful next question is what you are actually buying when you commit capital to a fund: how the vehicle is structured, what sits inside it, where the return comes from, and the specific terms that decide whether you keep it. Three things run throughout. How the fund is built (a closed-end drawdown vehicle behaves nothing like an evergreen one). Where the return really comes from (the coupon is only one part of it). And where the risk actually sits (which is rarely the place the brochure points you).

Here is the claim the rest of the article defends. The words “private credit” on a fund tell you almost nothing about your outcome. Two funds can carry the same label and hand you completely different results, because what governs your return is the fee basis, the liquidity terms and how the manager values assets that never trade. Most investors read the strategy page hard and skim the terms. It should be the other way round.

What You Are Buying When You Invest In A Private Credit Fund

A private credit fund pools investor capital and lends it to companies through loans that do not trade on public markets. That last part is the whole point and the whole risk. Because the loans do not trade, there is no live market price. The fund tells you what they are worth, on its own schedule, using its own models. Hold that thought, because it comes back at the end and it is the thing most investors under-check.

The label matters far less than the strategy underneath it. Risk, documentation and recovery all shift depending on what the fund actually lends against.

  • Direct lending to mid-sized companies. Usually senior secured loans to businesses owned by private equity sponsors, with covenants and security over assets. This is the bulk of the market and the most conservative end of it.
  • Unitranche. Senior and junior debt blended into one instrument, priced above pure senior debt, usually giving the lender tighter control in return for speed and certainty for the borrower.
  • Asset-backed lending. Loans secured against contracted cashflows or hard collateral such as equipment, receivables or specialist finance. The underwriting question is whether the asset performs, not whether company earnings grow.
  • Special situations and opportunistic credit. Distressed debt, rescue financing and structured deals. Wider range of outcomes, more equity-like risk, and the place where manager skill separates most.

At the fund level, “private credit” can therefore mean cautious first-lien lending or bespoke distressed deals with equity-shaped risk. That gap is why choosing a manager is really choosing a strategy. The Federal Reserve’s own analysis puts direct lending at the centre of the market, which tells you where most of the capital and most of the competition sits.

Why The Market Grew This Fast

Two forces built the market. Banks retreated from parts of corporate lending after the post-2008 capital rules made those loans expensive to hold, and private lenders stepped into the gap with tighter documentation and higher spreads than banks used to earn. That is the supply side. On the demand side, allocators wanted a return stream driven by contracted interest payments rather than equity multiples, which looks attractive when equity outcomes are wide and bond returns swing with interest-rate duration.

Rates changed the product itself. Most middle-market loans are floating-rate, so the coupon resets off a reference rate. For dollar loans that is usually the Secured Overnight Financing Rate published daily by the New York Fed; sterling loans reset off SONIA and euro loans off EURIBOR, but the mechanism is identical wherever the fund lends. When base rates rose after 2022, coupons rose with them, and floating-rate credit went from a modest yield to a headline one. That is also the seed of a risk we come back to: a higher coupon is only good news if the borrower can still pay it.

How Private Credit Funds Work In Practice

What you experience as an investor is set mostly by one choice: the vehicle. A closed-end drawdown fund and an evergreen fund are marketed as the same asset class and behave like different products. The table below lays the two side by side. First, the mechanics.

Drawdown (Closed-End) Funds

The classic institutional vehicle is a closed-end drawdown fund. You commit an amount, say £5m, and the manager calls that capital over roughly 12 to 36 months as it originates deals. Your money is not earning until it is deployed, and you typically pay management fees on your committed amount during the investment period, not just on the portion actually working.

Three consequences follow. You carry pacing risk, because you are exposed to how fast and how well the manager deploys in that vintage. You get a J-curve, where early returns look soft because fees are running against partially invested capital. And you cannot redeem. Your capital is locked for the fund’s life, often eight to ten years, and your only early exit is selling your stake on the secondary market, usually at a discount when buyers are scarce.

Evergreen, Interval Funds And Listed Vehicles

Evergreen funds, including the semi-liquid interval funds that have pulled in most of the recent retail money, aim to stay continuously invested and offer periodic liquidity windows. Those windows come with hard limits, and the limits are where the trouble lives.

A non-traded business development company (BDC) typically caps redemptions at 5% of net asset value per quarter. An interval fund usually allows around 1% of NAV monthly and up to 5% per quarter. There is a real structural difference between the two that the “semi-liquid” label hides. An interval fund is legally required to honour its repurchase offer up to the cap. A non-traded BDC or tender-offer fund can gate redemptions entirely if its board approves, and boards do exactly that when requests spike.

They spiked in 2025 and 2026, which is why this stopped being theoretical. Non-listed BDC redemptions as a share of quarter-opening NAV almost tripled to 4.71% in one quarter. In February 2026, Blue Owl closed quarterly redemptions on its OBDC II vehicle and switched to returning capital gradually instead. Cliffwater’s Corporate Lending Fund took redemption requests on 14% of shares in one quarter against a 7% cap, so investors who wanted out got roughly half of what they asked for and had to queue for the rest. The “liquid” part of semi-liquid is only there until everyone wants it at once.

Listed BDCs solve the exit problem and create another one. You can sell on a public exchange any day, but the share price trades on sentiment, and it can sit at a discount or premium to the underlying loans. The loans might be perfectly stable while your holding drops with the wider equity market. You have swapped capital calls and lock-ups for daily price volatility.

The BDC and interval-fund names are American, because the wrappers are. The same mechanics reach investors elsewhere under different labels, and the label is the first thing to check wherever you are resident. In the UK the equivalent evergreen wrapper is the Long-Term Asset Fund (LTAF), a regulated open-ended vehicle for illiquid assets that becomes eligible for stocks-and-shares ISAs in 2026. In the EU it is the ELTIF 2.0 regime, which added evergreen open-ended structures and cut the minimum illiquid-asset floor from 70% to 55%, driving a wave of retail-accessible private-credit ELTIFs; AXA IM Alts, for instance, launched an evergreen direct-lending ELTIF with periodic liquidity windows in 2025. Some managers also run private credit inside a UCITS-style wrapper, which buys daily dealing at the cost of holding only the more liquid, traded slices of the market rather than the illiquid direct loans. And the listed route is not US-only: the London Stock Exchange hosts closed-ended debt trusts such as the FTSE 250 constituent Sequoia Economic Infrastructure Income Fund (LSE: SEQI), launched in 2015 to lend into infrastructure projects, which trade daily and can sit at a discount or premium to NAV exactly as a listed BDC does. Australia, Canada and Asia each have their own listed and unlisted equivalents. The wrapper changes; the four questions that follow do not.

Origination: Where The Manager’s Edge Actually Sits

One more mechanic decides quality: how the fund sources deals. Managers with repeat sponsor relationships, sector focus and in-house underwriting tend to see better terms and get first look at the good deals. When a deal is broadly shopped to every lender in the market, the borrower is optimising for the cheapest, most lender-friendly money, and the manager’s edge has to come from credit selection rather than documentation. If you want the full foundation first, our private credit guide covers the ground beneath this, and our direct lending deep dive goes deeper on the engine room of the market.

Where The Returns Actually Come From

Most investors start and stop with headline yield. The return breaks into four drivers, and only some of them repeat.

Contracted income: base rate plus spread. The core of it. Your coupon is a reference rate such as SOFR, SONIA or EURIBOR plus a negotiated spread. It rises when base rates rise and falls when they fall, unless the loan carries a floor. This driver is repeatable, but only if the borrower’s cashflow can absorb the coupon without its credit metrics deteriorating.

Fees the borrower pays you. Private lending carries fee layers public bond investors rarely see. Upfront arrangement fees and original issue discount lift the effective yield above the stated coupon. Amendment and consent fees arrive when borrowers need covenant resets or maturity extensions, which means they show up most in stressed periods, exactly when you want a cushion.

Downside protection through covenants and security. Many private loans are senior secured and carry more covenants than the broadly syndicated loans that trade publicly. Covenants do not stop losses, but they change the timing. They let a small, coordinated lender group intervene early when a borrower slips, and earlier intervention usually improves recoveries. Fitch’s 2025 data showed six of eight resolved defaults in one monitored portfolio paying first-lien lenders back in full, with the other two recovering between 70% and 90%, which is the covenant-and-security mechanism working.

Selective equity-linked upside. Some strategies add warrants, success fees or payment-in-kind toggles. This is not free return and it is not universal, but it explains why certain managers clear a simple coupon profile.

Watch the payment-in-kind line closely, because it is where reported return and cash return quietly separate. Payment-in-kind means the borrower pays interest by adding to the loan balance rather than sending cash. Structured in at origination it is normal. Deferred mid-loan because a borrower is short of cash, it is a warning. By Q4 2025, 6.4% of private credit loans carried “bad PIK” of that stressed kind, close to triple the 2021 level. A fund can report a healthy yield while a growing slice of it is paper interest it has not actually collected.

Fees And Terms: What “Expensive” Actually Means

Ask the wrong fee question and the number misleads you. The question is not “is it 1% or 1.5%?” It is what the fee is charged on, and when.

Two things matter most. The management fee basis, committed versus invested capital, decides how much slow deployment costs you, because a fee on committed capital charges you for money that is not yet working. And the incentive fee, usually a share of profits above a hurdle rate, decides how much of the upside the manager keeps. The traditional structure was 2% management and 20% of profits, but the market has spread out. The Spring 2025 BDC Monitor put average management fees across BDCs between 1.27% and 2.33%, incentive fees around 18% to 20%, and hurdle rates between roughly 6.8% and 7.5%.

Here is why the hurdle number matters more than most investors realise. Take a fund earning a 10% gross return, charging a 1.25% management fee and a 12.5% incentive fee above a 7.5% hurdle. Strip the management fee and you are at 8.75%. The manager then takes 12.5% of the 1.25% above the hurdle, roughly 0.16%, leaving you near 8.6% net. Now run the same fund at a 20% incentive fee and no hurdle at all: the manager takes 20% of the full return above the fee, and your net drops toward 7% on the same gross performance. Same 10% gross, and the terms alone move your net by more than a percentage point and a half. The headline fee rate did not tell you that. The basis and the hurdle did.

The honest fee question for any private credit fund is what net return is realistic after fees, credit losses and cash drag across a full cycle, not what the top-line management fee looks like in the brochure.

The Structure Comparison Most Fact Sheets Do Not Give You

Here is the side-by-side, assembled from current fund terms and 2025 market data. Figures are typical ranges as at July 2026, not any single fund, and terms vary by manager. The three structures are the shapes, not the labels: the “non-traded / interval evergreen” column is the US BDC and interval fund, the UK LTAF, and the EU ELTIF 2.0 evergreen alike, and the “listed” column covers a listed BDC on a US exchange and a listed debt trust such as SEQI in London equally. Read the column that matches the structure, whatever it is called where you are resident.

Feature Closed-end drawdown Non-traded / interval evergreen Listed BDC
Access Capital called over 12 to 36 months Subscribe at NAV, ongoing Buy shares on an exchange
Liquidity Locked ~8 to 10 years; secondary sale at a discount Periodic windows, ~5% NAV per quarter, board can gate Daily, on-market
Typical fees ~1.5% to 2% management + ~15% to 20% carry over a hurdle ~1.25% management + ~12.5% incentive over a ~7.5% hurdle ~1% to 1.5% management + incentive fee
Fee basis catch Often charged on committed capital during investment period Ongoing servicing and admin layers Fee on gross assets magnifies with leverage
Fund-level leverage Common, adds return and risk Common, regulatory limits apply Regulated up to 2:1 debt-to-equity
Pricing Manager NAV, updated periodically Manager NAV, monthly or quarterly Live share price, can trade below NAV
The catch J-curve, no exit, deployment pacing Gates activate exactly when you want out Share price swings with equity sentiment

Where The Risk Actually Sits

Private credit risk is not just defaults. It is a stack of exposures that surface at different times, and the one that gets read first is rarely the one that bites.

Credit risk shows up late. Private loans can look stable right up until they are not, because valuations are model-based and updated periodically rather than marked to a live market. Reported default rates in 2025 ranged widely by methodology, from the Cliffwater Direct Lending Index trailing rate near 1.45% to a Fitch middle-market portfolio at 9.2%, which tells you the number depends heavily on what is being measured. A calm headline default rate can hide stress building underneath.

Liquidity risk is structural, not accidental. The gates covered above are not a malfunction. They are the design working as intended, and they trigger precisely when many investors want out together. If you might need the money inside the fund’s stated window, the window’s cap is a real constraint, not a formality.

Refinancing risk sits with the borrower. Most of these loans are bullets that need refinancing at maturity. If credit markets are tight when that maturity arrives, a borrower who was servicing the debt fine can still fail to refinance, and an amendment fee to extend the loan is not the same as being repaid.

Valuation governance is the risk almost nobody checks. This is where the piece started and where it ends. Because the loans do not trade, the NAV you see is the manager’s estimate, and the manager charges its fee off that same NAV. In Q4 2025 BlackRock’s TCP Capital wrote down its NAV by 19% in a single quarter, which is not how a portfolio behaves if its interim marks were tracking reality. The mark was catching up to something the model had been smoothing over. The question to ask a private credit fund is not only “what do you own?” but “who values it, how often, and who checks their marks?” Most investors never ask the second one.

The Due-Diligence Checklist That Actually Separates Funds

Built from the named fund terms above. It applies wherever the fund is domiciled and wherever you are resident, because the six questions test the mechanics of the structure, not the rules of any one country. Work top to bottom and the fund that looks like every other one on the strategy page starts to differentiate. One point that does turn on jurisdiction is tax: a fund’s home-country treatment, such as withholding on distributions at source, is a property of the wrapper and treaty-dependent, while how the income is taxed in your hands depends on where you are resident. That is the question to put to an adviser, not to guess from the fact sheet.

  1. Fee basis, not fee rate. Is the management fee on committed or invested capital? Is there a hurdle before the incentive fee, and what is it? A fund with a 7.5% hurdle keeps far less of your upside than a no-hurdle fund at the same headline rate. 2. Redemption mechanics, in writing. What is the cap, how often does the window open, and can the board gate? For anything you might need back, treat the cap as the real liquidity, not the marketing word. 3. Fund-level leverage. Does the fund borrow to boost returns, and how much? Leverage lifts the good years and deepens the bad ones, and a fee on gross assets grows with it. 4. Valuation governance. Who marks the loans, how often, and is there an independent third-party valuation? Ask about the largest single-name write-down in the last two years and how long the mark took to catch up. 5. Payment-in-kind exposure. What share of income is paid in kind rather than cash, and how much of it was structured at origination versus deferred later? Rising deferred PIK is reported yield you have not been paid. 6. Origination model. Does the manager source proprietary deals or buy broadly shopped ones? Repeat sponsor relationships usually mean better terms and earlier looks.

Most investors run the first item and the strategy page hard, then skim the rest. The funds that survive a full cycle are usually the ones that pass items two, four and five, and those are the three most people never check.

FAQs

What is the difference between a private credit fund and a bond fund?

A bond fund holds securities that trade on public markets, so it has a live daily price. A private credit fund holds loans that do not trade, so its value is the manager’s periodic estimate, and getting your money out depends on the fund’s redemption terms rather than a market.

Are private credit funds liquid?

Mostly not. Closed-end drawdown funds lock capital for the fund’s life. Evergreen wrappers, whether a US interval fund or non-traded BDC, a UK LTAF or an EU ELTIF 2.0, offer periodic windows, typically capped near 5% of net asset value per quarter, and those caps can be gated by the board when redemption requests spike, as happened across 2025 and 2026. Listed vehicles, a US-listed BDC or a London-listed debt trust alike, trade daily but at a share price that can drift from NAV.

Do private credit funds exist outside the US?

Yes. The market is global and only the wrappers differ. The US uses BDCs and interval funds; the UK has the Long-Term Asset Fund; the EU has the ELTIF 2.0 evergreen regime; listed closed-ended debt trusts trade in London and elsewhere; and some managers run the more liquid slices inside a UCITS wrapper. The strategy, fee and valuation questions here apply to all of them, whatever the fund is called where you live.

What fees do private credit funds charge?

Usually a management fee plus an incentive fee on profits above a hurdle. Across BDCs in 2025, management fees ranged from about 1.27% to 2.33% and incentive fees sat around 18% to 20%. What matters more than the rate is the basis (committed versus invested capital) and whether there is a hurdle.

What is the biggest risk in a private credit fund?

The one investors check least: valuation governance. Because the loans do not trade, the reported NAV is a model estimate, and a sudden large write-down usually means the mark was lagging reality rather than the portfolio changing overnight.
