The steady loan spread compression since early 2024 has been particularly negative to long-dated CLO equity, especially those issued in 2024 that remain in their non-call period. This feature benefits CLO debt investors, who are able to lock in wider spreads for longer, but comes at the expense of equity holders.
This week saw a list of seasoned EU CLO BBB bonds, all of which received covers well above par, with discount margins in a narrow range of 302–311 bps. This is despite their varying reinvestment end dates. Two bonds have passed their reinvestment period (RP) by over two years, one has just concluded its RP, and two have RPs ending in 2026.
Table 1 below provides the full list of 70 EU CLO managers overseeing a total of €268 billion (US$316 billion) in CLO collateral assets under management (as opposed to CLO liabilities) as of 30 June 2025, along with AUM trends since 31 December 2017. Since 31 December 2020, CVC Credit Partners, Palmer Square Capital Management, and RRAM have seen the most significant increases in collateral AUM notional among EU CLO managers. Only Blackstone and Carlyle have remained in the top five since 2017; the others have dropped out of the top five managers by collateral AUM.
AAA spreads in both the US and EU CLO markets remain wide relative to their year-to-date averages.
Both primary US BSL and EU CLO AAA tranches are currently pricing wide relative to year-to-date averages, which negatively affects new issue equity arbitrage. That said, the market is likely to self-correct over time, and as long as loan market conditions remain strong, there is no reason AAA spreads should not tighten further.
Selected takeaways from yesterday’s CLO panel discussions:
How do emerging CLO managers compare with their peers?
Please refer to the table below for a comprehensive list of CLO managers and their global CLO collateral AUM (in USD billions), rather than CLO liabilities, broken down by US BSL, US MM, and EU CLOs, as of 31 March 2025.

Notably, 33 managers have grown their BSL CLO AUM by more than $1 billion per year since pricing their first deal.

In contrast, there were no EU CLO deals with negative equity NAV as of 7 March, but by 14 April 2025, 22 deals—or 4.3% of the total sample—had moved into negative territory.
A more objective way to evaluate a manager’s capability is by examining the inception-to-date gross annualised collateral return of their deals, measured relative to the relevant loan indices and assessed on an unlevered basis. This provides a clearer measure of true alpha generation.
