Under the Hood of January’s Active Fixed Income ETF Explosion

Table of the top 10 active fixed income ETFs by inflows for January 2025, highlighting ETF symbols, names, share class assets under management (AUM), January 2025 inflows, and flows as a percentage of AUM. The Janus Henderson AAA CLO ETF leads with $3,154.35 million in inflows, constituting 15.86% of its AUM. Other notable ETFs include the SPDR Blackstone Senior Loan ETF with $1,246.57 million in inflows (13.48% of AUM) and the JPMorgan Ultra-Short Income ETF with $738.40 million (2.56% of AUM). The table also displays trailing 12-month flow percentages relative to AUM for each ETF.

To say that the first month of 2025 was a big one for fixed income hardly does it justice. 

US-domiciled bond-based mutual funds and ETFs drew an impressive $41.4 billion in net new assets, surpassing money market funds by over $30 billion.

All ten strategies on this list have crossed the billion-dollar AUM milestone, with each experiencing at least 10% of their end-of-January AUM from inflows over the past year. Impressively, nine of these have seen more than a third of their assets accumulate in the last 12 months alone, highlighting the rapid growth of the active ETF market.

A critical aspect for all investment strategies, especially active ones, is how their underlying holdings set them apart from competitors or benchmarks. Using Quickflows in YCharts enables distribution teams to easily demonstrate their unique value with just a few clicks.
