A new breed of ETF promises to unlock the private credit market for everyone. But does this liquid solution for an illiquid asset create more problems than it solves?
For years, the $1.7 trillion private credit market has been the exclusive playground of institutional investors and the ultra-wealthy. Lured by high yields and diversification away from public markets, they poured money into funds making direct loans to companies. Now, a new wave of exchange-traded funds (ETFs) is trying to bring this asset class to the masses. But the controversial launch of the first actively managed private credit ETFs has ignited a debate about whether you can truly package an illiquid asset into a daily-traded product without breaking something.
The Great Liquidity Mismatch
The central controversy surrounding private credit ETFs is the liquidity mismatch. Private credit loans are, by their nature, illiquid. They are privately negotiated, don’t trade on an exchange, and can take months or even years to sell. ETFs, on the other hand, offer daily liquidity, allowing investors to buy and sell shares on demand. Liquidity is also one reason the private credit secondaries market has attracted more attention — as investors have sought ways to manage or exit illiquid positions before a fund’s natural end of life, secondaries have emerged as a practical, if still developing, solution to the same mismatch that makes private credit ETFs so structurally complex.
Regulators, specifically the U.S. Securities and Exchange Commission (SEC), have long been wary of this mismatch. Under SEC Rule 22e-4, ETFs are prohibited from holding more than 15% of their assets in illiquid investments. This rule is designed to ensure that funds can meet redemption requests from investors, even during times of market stress. The challenge for private credit ETFs is how to provide exposure to the asset class while staying within this 15% limit.
A Controversial Debut and the SEC’s Evolving Stance
The issue came to a head with the 2025 launch of the SPDR SSGA Apollo IG Public & Private Credit ETF (PRIV). For context, it helps to compare private credit with public credit and listed bond markets — the core tension with vehicles like PRIV is that private credit assets are illiquid by nature, while ETFs are built on the assumption of daily liquidity, and reconciling those two structures is what regulators are scrutinising. The fund, a partnership between State Street Global Advisors and private credit giant Apollo, aimed to provide significant exposure to private credit. However, shortly after its debut, the SEC raised concerns, pointing out “significant remaining outstanding issues” with the fund’s structure. The controversy centered on the fact that the fund was targeting a 10% to 35% exposure to private credit, which seemed to clash with the 15% illiquidity cap.
In response to the SEC’s inquiry, State Street agreed to rename the fund and affirmed it would adhere to the 15% cap on illiquid assets. This episode highlights the regulatory tightrope that private credit ETFs must walk and the SEC’s cautious approach to this new product category.
How Private Credit ETFs Work (and How They Differ)
Given the 15% illiquidity limit, private credit ETFs use a mix of strategies to provide exposure to the asset class. They typically hold a majority of their assets in liquid, publicly traded debt, such as corporate bonds, and then allocate a smaller portion to private credit. Some ETFs may also use other vehicles like Business Development Companies (BDCs) or Collateralized Loan Obligations (CLOs) as a proxy for private credit exposure.
This is where it’s crucial for investors to understand the differences between the various ways to access private credit:
| Feature | Private Credit ETFs | Business Development Companies (BDCs) | Interval Funds |
|---|---|---|---|
| Liquidity | Daily (traded on an exchange) | Daily (publicly traded BDCs) | Periodic (quarterly or semi-annual tender offers) |
| Structure | Open-end fund (ETF) | Closed-end fund, regulated under the Investment Company Act of 1940 | Closed-end fund |
| Leverage | Limited by fund’s strategy | Up to 2:1 debt-to-equity | Limited to 0.5:1 debt-to-equity |
| Direct Exposure | Limited (typically <15% direct private credit) | High (must invest at least 70% in private companies) | High |
| Transparency | High (daily holdings disclosure) | High (quarterly filings) | Lower (periodic reporting) |
| Fees | Generally lower than BDCs and interval funds | Can be high, with management and performance fees | Often have high fees and sales charges |
Democratization or New Dangers?
Proponents of private credit ETFs argue that they democratize access to a previously inaccessible asset class, offering diversification and potentially higher yields to retail investors. They provide a liquid, low-cost way to get a taste of private credit without the high minimum investments and long lock-up periods of traditional private credit funds. Private credit ETFs should also be compared with traditional private credit funds directly — while the ETF wrapper lowers the barrier to entry, it also changes the exposure in ways that matter: the liquidity premium, covenant protections, and deal access that define traditional fund returns may not fully translate into a listed vehicle.
However, critics warn that these new products could be creating new risks. The liquidity mismatch remains a key concern. In a market downturn, if many investors rush to sell their private credit ETF shares, the fund could be forced to sell its more liquid assets to meet redemptions, leaving it with a concentrated portfolio of illiquid, hard-to-value loans. This could lead to a
downward spiral in the ETF’s price, detached from the actual value of its underlying assets.
Furthermore, the use of proxies like BDCs and CLOs means that investors in private credit ETFs may not be getting the pure-play exposure they think they are. They are also exposed to the risks of these other investment vehicles, which have their own complexities and potential pitfalls.
The Bottom Line
Private credit ETFs represent an innovative attempt to bridge the gap between the public and private markets. For sophisticated investors who understand the risks, they can offer a convenient and low-cost way to add a slice of private credit to a diversified portfolio. However, the notion that they provide true, liquid access to an illiquid asset class is a simplification. The liquidity mismatch is a real and present danger, and investors need to be aware that in a crisis, the liquidity they count on from the ETF wrapper may not be there.
Ultimately, private credit ETFs are not a free lunch. They are a compromise, offering a taste of private credit’s potential returns in exchange for a new set of risks. Before jumping in, investors should do their homework, understand how the specific ETF they are considering is constructed, and be prepared for the possibility that this liquid solution could spring a leak.
