Syndicated bank loans, once considered a niche asset class, have grown in popularity and scope, according to new insights from Morningstar Indexes based on the Morningstar LSTA US Leveraged Loan Index.
In fact, according to Dan Lefkovitz in his recent Morningstar.com article on fixed-income market flows and investor preferences, Morningstar’s bank loan category for funds is one of the fastest growing in Morningstar’s database, and the US syndicated bank loan market is now larger in value than the market for high-yield bonds.
Lefkovitz goes on to cite some reasons investors may be attracted to syndicated bank loans. Unlike high-yield bonds, bank loans have floating-rate coupons, so their yields rise along with interest rates. The Morningstar LSTA US Leveraged Loan Index yielded nearly 9% as of March 7, 2025. And while bank loans’ credit risk profile does increase their correlation with equities, they have held their own, as have other fixed-income asset classes, amid the US equity market selloff of 2025’s first quarter.

The long-term growth story of bank loans is also linked to the convergence of public and private markets, as explained by Elizabeth Templeton of Morningstar Indexes.

“Credit investors are increasingly viewing leveraged loans as an attractive asset class. The Morningstar LSTA US Leveraged Loan Index is often used as a proxy for private credit. Not only are many loan issuers backed by private equity investors, but collateralized loan obligations are big buyers of loans.”
