In the CLO market, AUM growth is a fundamental aspect of the business model, with scale playing a crucial role...
Given the significantly smaller base of US MM CLO AUM, it is unsurprising that annual growth has continued to remain in double figures. In contrast, US BSL CLO AUM recorded growth rates of just 3.3% and 4.3% in 2024 and 2023, respectively, both of which were lower than the 9.2% growth rate recorded in 2020.
Kindly consult the table below, which illustrates the trends in 2.0 MM CLO AUM for each US MM CLO manager since 2012. The year-end notional AUM (in billions of dollars) for each period is determined based on the pricing dates of CLO transactions and the notional value of the underlying collateral.
