Banks Are Piling Back Into Everything From Mortgage Debt to CLOs

US banks are starting to ramp up purchases of everything from mortgage-backed securities to collateralized loan obligations after nearly two years of cutting back, adding fuel to a multi-month rally across credit markets.

Citigroup Inc., JPMorgan Chase & Co. and Bank of America Corp. have been boosting purchases of top-rated CLOs. Commercial bank holdings of mortgage bonds are also on the upswing, climbing 12 of the last 15 weeks, according to Federal Reserve data. It comes as Wall Street buyers added $41 billion of securities to their portfolios in the three months through December, according to data compiled by Citigroup, ending a streak that saw them shed more than $800 billion since March 2022, separate Fed data show.

Amid an upturn in deposits, banks are searching for ways to put this new cash to work. The traditional option — boosting lending — is hard to do right now, though, after two years of interest-rate increases that curbed loan demand and pushed up defaults. That’s left banks to park more money in high-quality securities that they believe will boost returns without heaping on too much credit risk.

The renewed demand, while thus far modest, is already helping propel gains across credit, market watchers say. Spreads on new CLOs have tightened to the narrowest in more than a year-and-a-half in recent weeks, while MBS have rebounded from historically cheap levels. Further signs that banks are adding to their CLO and MBS holdings will only bode well for those markets, according to John Kerschner, head of US securitized products at Janus Henderson.

“The credit rally has multiple drivers, but an important piece of it is bank demand and we’re expecting only to see more of that,” Kerschner said.
