The Private Credit Illiquidity Premium Is Quietly Disappearing

Private credit's central sales pitch has a quiet problem, and the legal industry noticed before most advisors did. A Dechert analysis published on Mondaq August 17, 2026 documents how business development companies (BDCs are publicly registered vehicles that make private loans to mid-sized companies) have spent the past two years building an increasingly elaborate financing toolkit. The reason that toolkit needed building is the part nobody puts on the pitch deck. Direct-lending deals originated in 2017 and 2018 paid BDCs more than 300 basis points (a basis point is one-hundredth of one percent, so 300 bps equals 3 percentage points) over what the same borrower would have paid in the public leveraged loan market. By the first quarter of 2026, according to PIMCO strategist Lotfi Karoui, that advantage had fallen to less than 100 basis points. I want to walk you through what that number means, why it is happening while $190 billion poured into the asset class in six months, and what questions it should put in your mouth the next time someone pitches you a "safe yield" private credit allocation.

What the illiquidity premium actually is

Here is the plain-English version. When you lend to a public company through the broadly syndicated loan market, you can sell that loan tomorrow. There is a price, a dealer desk, and a secondary market. When you lend through private credit, typically via a BDC or a private debt fund, you are locked in. The manager negotiates a bespoke loan directly with a borrower, holds it to maturity or workout, and reports its value quarterly using an internal model rather than a market price. You give up the ability to exit on demand. In exchange, the theory goes, you get paid more.

That extra pay is the illiquidity premium. Cliffwater LLC, which runs the most widely cited benchmark for this trade (the Cliffwater Direct Lending Index), has calculated the long-run illiquidity premium at roughly 3.5 percentage points over public high-yield markets going back two decades. BlackRock's own research pegs the 10-year average yield premium between private and public credit at 4.2%, and flags that it has been compressing for three straight years.Research from NISA Investment Advisors, published in January 2026, found the gross premium runs 2.6% to 3.7% depending on the measurement window, but after private credit's management fees are deducted, net excess return over the last 20 years falls to about 60 basis points. Only 9% to 32% of the theoretical premium actually reaches the investor's pocket once fees are paid.

I am giving you three different research shops because I want you to see the range: 60 basis points to 420 basis points, depending on whose adjustments you accept and whether you are looking at fees gross or net. Karoui's 2017-2018 vintage number, more than 300 basis points, sits at the generous end of that range. His Q1 2026 number, under 100 basis points, sits below every estimate above except the fee-adjusted NISA figure. That is the compression in one sentence: new deals today are pricing closer to the worst-case historical premium than the best-case one.

The compression data, and it is not just one strategist's opinion

Karoui's spread math, cited in an August 17, 2026 Benzinga report on BDC stock skepticism, is not an outlier. Reuters reported in May 2026 that risky syndicated loans were pricing about 200 basis points cheaper than comparable private direct loans, cheap enough that bankers said borrowers were actively considering switching financing sources. A Federal Reserve staff note published in August 2026 on private credit and leveraged loan substitution found middle-market direct loans pricing around SOFR (Secured Overnight Financing Rate, the base rate most floating-rate loans are quoted against) plus 500 basis points against broadly syndicated loans around SOFR plus 400, a gap that has narrowed sharply from prior cycles as borrowers increasingly shop both markets against each other. Octus data on the large-cap segment showed similar convergence: broadly syndicated spreads near SOFR plus 300 in late 2025, private large-cap direct loans near SOFR plus 480 to 500, a gap that has been grinding tighter for two years.

The Dechert piece adds a structural detail that confirms the same story from a different angle. Middle-market CLOs (collateralized loan obligations, pools of loans packaged and sold in tranches to investors) and the broadly syndicated CLO market, historically two distinct markets with different borrowers and different buyers, are converging as private credit scales. Some middle-market CLO platforms are now originating upper-middle-market loans that overlap directly with syndicated territory. Dechert also notes that BDCs are leaning harder on term CLO financing precisely because bank ABL (asset-based lending) facilities have gotten more expensive and less available. Put together: the assets private credit funds hold are pricing more like public assets, the financing behind those funds is starting to resemble public securitization more than bespoke bank lines, and the equity capital chasing the arbitrage is shifting toward captive, BDC-affiliated sources rather than independent third-party money, because independent equity investors increasingly want a premium that compressed spreads no longer offer.

Why capital is still flooding in anyway

None of this has slowed fundraising. With Intelligence data shows private credit closed $190 billion in H1 2026, up 53% from H1 2025, with direct lending alone accounting for nearly $100 billion of that total. That is not a market pausing to ask questions. That is a market accelerating into a spread that has fallen by roughly two-thirds from its 2017-2018 level.

I think three forces explain the disconnect. First, headline yields still look attractive on an absolute basis. Cliffwater's research shows direct lending yielding around 11% to 12% in the current rate environment, and most allocators anchor on that number rather than on the spread over comparable public credit. An 11% yield feels good regardless of whether 300 basis points or 80 basis points of it represents genuine compensation for illiquidity versus just floating-rate exposure to a still-elevated SOFR. Second, private wealth and retail-adjacent channels, interval funds, non-traded BDCs, wealth management platforms, have only recently gained meaningful access to this asset class, and that access itself is driving inflows independent of pricing. Third, and this is the one advisors rarely say out loud: allocators who committed capital to private credit funds years ago are recycling distributions back into new vintages because that is the mandate, not because the new vintage offers the same economics as the one that matured.

The asymmetry this creates

Here is the setup that should worry you more than any single data point. You are being asked to give up daily liquidity, accept quarterly model-based valuations instead of market prices, and often lock up capital for years, all in exchange for a premium that has fallen from over 300 basis points to under 100. At the same time, Fitch Ratings reported that the U.S. private credit default rate hit a record 6.0% for the twelve months ended Q2 2026, up from 5.7% the prior quarter, driven by stress in healthcare and industrials. And per Karoui's PIMCO research cited in Benzinga, BDC bonds have recovered most of their recent underperformance while BDC equities have not, a valuation divergence that reflects growing doubt about whether reported net asset values actually reflect what the underlying loans are worth. Equity holders sit below bondholders in the capital structure and are the ones absorbing losses first if those NAVs get marked down, and Karoui pointed to the 2022 private real estate cycle, where private valuations initially resisted a public market decline before eventually converging with it, as a plausible precedent.

Stack those three facts. Compensation for illiquidity is falling. Default risk is rising to record levels. And the instrument used to value your locked-up position is showing signs of lagging reality rather than reflecting it in real time. None of that means a crash is coming, and I am not predicting one. What it means is that the same allocation that looked like "extra yield for a liquidity haircut" in 2018 increasingly resembles "public-market credit risk, illiquid wrapper, smaller haircut discount" in 2026. You are taking on more risk of the kind public markets already price efficiently, while giving up more optionality, for a shrinking reward. That is the asymmetry. It does not require anything to break. It just requires the math to keep drifting the direction it has been drifting since 2018.

Questions to ask before you allocate

Before you commit new capital to any private credit fund, direct lending BDC, or interval fund, ask the manager these questions directly and expect specific numbers back, not a general pitch about the asset class's history.

What vintage is this fund actually deploying into right now. A fund that raised capital in 2021 and is showing you a blended 10-year track record is not the same thing as a fund putting new dollars to work in the current spread environment. Ask what spread the manager's most recent five deals priced at, not the fund's since-inception average.

What is the actual spread over comparable public credit, measured today, for the specific loans this fund is originating. If the manager cannot give you a SOFR-plus number and compare it to where a similarly rated broadly syndicated loan or CLO tranche is pricing this quarter, that is itself informative. The Federal Reserve, Octus, and Fitch data cited above exist precisely so you can sanity-check the answer.

What is the redemption gate structure, and has it ever been triggered. Interval funds and non-traded BDCs typically offer periodic redemption windows capped at a percentage of net assets, often 5% per quarter. Ask what percentage of redemption requests were actually honored in the fund's most stressed recent quarter, and what happens to your money if requests exceed the gate.

How is the loan portfolio marked, and by whom. Internal marks reviewed only by the manager's own valuation committee deserve more skepticism than marks validated by an independent third party using observable market comparables, especially given Karoui's point that BDC portfolios have shown limited evidence of markdowns despite two-plus quarters of redemption pressure and rising defaults elsewhere in the market.

What is the fee load, all-in, net of which the illiquidity premium has to clear before you see a dollar of it. Per NISA's research, fees have historically consumed 68% to 91% of the gross premium. A manager quoting you gross spread numbers without discussing net-of-fee economics is not giving you the number that matters.

Frequently Asked Questions

Is the illiquidity premium gone entirely?

No. Karoui's data shows it compressed from over 300 basis points on 2017-2018 vintage deals to under 100 basis points by Q1 2026, and other research shops put the historical range anywhere from roughly 60 basis points net of fees to over 400 basis points gross, depending on methodology and period. The premium still exists. It is thinner than the number most sales pitches quote, and thinner than it has been in years.

Does this mean private credit is a bad investment now?

Not necessarily, but it means the reward for illiquidity has shrunk while default rates and valuation uncertainty have both increased. Whether an allocation still makes sense depends on your liquidity needs, the specific manager's underwriting discipline, and the actual spread on the vintage you would be buying into, not on the asset class's historical average.

Why are BDC bonds performing better than BDC equities right now?

Bondholders have a senior claim on the underlying loan portfolio, so they are less exposed to questions about whether reported net asset values are accurate. Equity holders absorb losses first, and per Karoui's PIMCO analysis, equity investors are increasingly skeptical that current NAV marks reflect what the loans are actually worth, especially given the record 6.0% default rate Fitch reported for Q2 2026.

What is driving the convergence between private credit and public leveraged loan pricing?

Scale. As documented in the Dechert analysis, private credit has grown large enough that middle-market CLOs and broadly syndicated CLOs are increasingly financing overlapping borrowers, and BDCs are turning to term CLO financing rather than relying solely on bank credit lines. Reuters and Federal Reserve research both show borrowers actively comparing pricing across the two markets and switching when the gap gets wide enough to matter, which itself pushes the two markets' pricing closer together over time.
