CLO Research

Below are tables presenting the MVOC (BB–B) and equity NAV of US BSL and EU CLO deals by vintage, based on asset prices as of 26 June 2026.

This model tracks reported WAS and WARF trends across 129 US BSL CLO managers, with monthly data dating back to April 2013. Select up to five manager-vintage combinations from the dropdown menus, and the chart will instantly compare their WAS and/or WARF levels.

Over the past year, more than 2,000 BWIC line items for rated EU CLO bonds have been observed. Among them, 261 line items across the AAA to single-B rating spectrum were called at par. Of these, 218 had a cover price at or above par, while 43 had a cover price below par.

The table below shows the average annualised prepayment rates for each seasoned manager in the first, second, third, fourth and fifth years of the post-reinvestment period (post-RP). The sample includes seasoned deals that had exited their reinvestment periods by 31 December 2024. Eight EU CLO managers have maintained single-digit annualised prepayment rates during either the first and second years or the second and third years of the post-RP period across their seasoned deals.

Over the past month, trading colour was available for more than 470 data points (source: SCI). The table below presents the average DMs and DMs to first call based on cover bids, grouped by WAL cohort.

A sample of 1,654 US BSL CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 55% are excluded.

The technically strong loan market, with around half or more loans trading above par, has resulted in a relatively active month-to-date secondary market for EU CLO single-B tranches. A total of 27 single-B tranches have traded on BWIC with trading colour available (source: Structured Credit Investor). For deals with reinvestment periods ending between late 2028 and 2030, discount margins (DMs) based on cover prices span a wide range, from 830 bps to 1,340 bps. As shown in the table in this article, DMs can rise sharply once MVOC falls into the 102.0%–102.5% range, with levels approaching 1,000 bps. Beyond this point, DMs tend to widen disproportionately with each incremental decline in MVOC, highlighting the increasingly asymmetric risk profile of investing in single-B tranches...

A sample of 577 EU CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 60% are excluded.

The table below presents benchmark BB tranche discount margins (DMs) for US CLOs with reinvestment periods ending in 2029-2031, across different MVOC bands and manager tiers. The benchmark levels are derived from average DM prints by MVOC band and manager tier, based on trading colour (source: SCI) observed since mid-April.

A sample of 579 EU CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 60% are excluded.

Below are tables presenting the MVOC (BB–B) and equity NAV of US BSL and EU CLO deals by vintage, based on asset prices as of 12 June 2026.

Arbitrage in the first half of 2025 was healthy, supported by wider asset spreads and tighter liability prints. In the second half of 2025, however, it generally ranged between 144 and 156 bps. When volatility spiked in February 2026, arbitrage improved to levels seen in early 2025, although it subsequently narrowed again, with the latest readings in the range of 150–160 bps.

A sample of 333 deals from the 1Q 2024 to 4Q 2024 vintages is used, excluding static deals and those with a collateral factor below 0.75. Each deal’s underlying collateral weighted average spread (WAS) is adjusted to reflect its weighted average price (WAP) as of June 5, 2026.
