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

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.

Overview of January Fixed Income ETF Flows
As you might expect, ETFs carried the bulk of the momentum. Across all peer groups, ETFs amassed $37.5 billion in net new assets, with Loan Participation, Short U.S. Treasury, and General U.S. Treasury ETFs accounting for nearly half of all fixed income ETF flows (48.1%).

The appeal of active management within the fixed income space persisted in January, with active fixed income ETFs capturing $16.7 billion in net new assets. Despite only making up over 15% of total assets, active inflows represented 44.6% of all fixed income ETF flows for the month.

The distribution of flows within active products was particularly concentrated, with Loan Participation, Ultra-Short Obligations, and Multi-Sector Income ETFs comprising nearly 60% (58.6%) of all active fixed income ETF flows. Notably, Loan Participation strategies alone accounted for over a third of these flows.

Below, we explore the most popular active fixed income ETFs in January, examining their allocation across fixed income sectors, credit quality, and geography.
Fastest Growing Active Fixed Income ETFs in January 2025
The Janus Henderson AAA CLO ETF (JAAA) led the pack by attracting $3.2 billion in net new assets in January, more than doubling the inflows of the second fastest-growing active fixed income strategy, the SPDR Blackstone Senior Loan ETF (SRLN), which secured $1.2 billion.
The JPMorgan Ultra-Short Income ETF (JPST) rounded out the top three, bringing in $738 million in inflows.

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.

The final comp table could be further customized to show exposure to Bank Loans, Asset Backed Securities (ABS), Commercial Mortgage Backed Securities (CMBS), and more.
