Total outstanding commercial and multifamily mortgage debt reached $5.02 trillion at the end of the first quarter, rising 0.5% or $26.3 billion during the first three months of 2026, the Mortgage Bankers Association (MBA) reported Thursday.
Multifamily mortgage debt accounted for $23 billion of that increase, climbing 1% during the quarter.
Reggie Booker, associate vice president of commercial research at the MBA, said the $5 trillion milestone “speaks to the resiliency and depth of commercial markets.”
“Multifamily continued to drive growth, with debt outstanding rising to $2.32 trillion as agencies, GSEs [government-sponsored enterprises] and banks steadily expanded their holdings,” Booker stated in a press release.
Despite what Booker called a “modest pullback” in the commercial mortgage-backed securities (CMBS) segment, he sees an overall market that “continues to move forward.”
