Investor interest in Collateralized Loan Obligations (CLOs) is climbing sharply, sparking debates on potential risks involved
In the world of structured finance, Collateralized Loan Obligations (CLOs) have been making headlines, with their market value reaching an impressive $1.4 trillion (£1 trillion) in April 2025. This rapid growth, however, has not come without concerns from regulators.
Regulators are warning of familiar risks such as underwriting discipline under pressure, increasing market concentration, and a troubling opacity in systemic oversight. Joanne McEnteggart, the Global Head of Debt, Capital Markets, and Corporate at IQ-EQ, has echoed these sentiments, highlighting the need for increased transparency and oversight to ensure the continued growth of the CLO market remains sustainable.
While CLOs have proven to be more resilient than expected, able to withstand market shocks and deliver consistent returns, the difference between resilience and fragility will come down to transparency and oversight. The resilience of CLOs is due to the diversified nature of their portfolios and the constant assessment of how assets within the portfolio are performing.
Despite the risks, the CLO market has shown increased transparency and oversight is needed. This is particularly important as the majority of CLO structures are in unregulated special purpose vehicles. Strong administration, rigorous reporting, and smarter use of data will be vital to protect investor confidence and ensure growth remains sustainable.
The European private credit market is primed for growth, with private debt managers switching to CLO products due to their liquidity, as stated by Joanne McEnteggart. The CLO market has nearly doubled in size since 2018, making it one of the fastest-growing areas of structured finance.
However, the jury is still out on whether the current boom in the CLO market reflects a market that has genuinely matured or is simply setting the stage for its next major stress test. Refinancing is the only option in the CLO market, leading to a lot of paper coming to the market across diverse sectors. This, coupled with the rapid rise of CLO ETFs, is democratizing participation in the asset class.
Yet, retail investors may not fully understand the risks they are taking on with CLO ETFs. CLOs must comply with securitization rules pertaining to risk retention, even though they are not exposed to the same regulatory scrutiny as an investment fund. CLOs offer many differing levels of tranche access depending on the investor's risk profile and returns appetite.
CLOs have come a long way since their association with the 2008 financial crisis. They have shown resilience and growth, but it is crucial to maintain transparency and oversight to ensure their continued success. The CLO market, once a source of concern, is now a beacon of growth in the structured finance world, but it must navigate its path carefully to avoid the pitfalls of the past.
