Last Thursday (24 April 2025) saw 27 tranches of EU CLO AA bonds, with a total notional of €61.5 million, traded via BWIC. The table below provides colour on some of the AA bonds with top-tier prints. Based on these covers and a simple extrapolation, the term structure of EU AA bonds would appear as shown in the second table.
The table below presents the annualised (orig) prepayment rates for seasoned EU CLO deals with reinvestment periods (RP) ending in 2022 across the first, second, third, and fourth years post-RP. Typically, deals experience a single-digit prepayment rate in the first year post-RP. The median post-RP prepayment rate increased to 21.3%, although the range of post-RP prepayment rates is wide.
Around 34% of single-B tranches from the 2012–2022 vintages had an MVOC below 100% even before the recent volatility triggered by the Liberation Day tariffs. As of 24 April 2025, that figure has risen to 40%, or 151 deals across 49 managers, as shown in the table below.

Tuesday’s BWIC colour included three distressed bonds originally rated single-B: two were covered at 31h, and one at around 10h. Discount margins were not reported, as it is highly unlikely these bonds will be repaid at par—an IRR-based approach would be more appropriate. Pricing these thin tranches remains particularly challenging, as even a small change in the underlying collateral NAV can significantly affect their value.
Market Value Over-Collateralization (MVOC), for instance, at the BB tranche level, is calculated by dividing the collateral market value (MV) by the sum of CLO liabilities (AAA to BB). MVOC is a crucial point-in-time metric for pricing CLO-rated tranches, closely monitored by primary and secondary market participants.

MVOC is a key point-in-time metric for valuing CLO-rated tranches, widely tracked by participants in both primary and secondary markets.
A total of 317 US BSL CLO deals are now showing a negative equity NAV, including 95 deals from the 2018 vintage. Among single-B tranches, 169 out of 411 deals—or 41%—have an MVOC below par.
