Banks Still Hold the Most
Commercial banks remain the biggest holders, with 38% of all commercial and multifamily mortgages, or $1.9 trillion, per MBA data cited by Commercial Property Executive. Agency and GSE portfolios and MBS rank second at 23%, or $1.2 trillion.
Life insurers carry $782 billion, a 15% share, and the CMBS, CDO and ABS category holds $651 billion, or 13%. MBA noted that many insurers, banks and GSEs also buy those securities, so the categories overlap, per Commercial Property Executive.
Multifamily Reaches $2.3 Trillion
Agencies and GSEs finance half of all multifamily mortgage debt, according to MBA. That makes them the dominant source of apartment capital.
Every major lender group added exposure during the quarter, including banks and thrifts, agency and GSE holdings, and securitization pools, Commercial Property Executive reported.
Debt Growth Meets a Rate Reset
Commercial Property Executive reported that MBA tied the Q2 growth to stronger borrowing activity and available capital. The expansion sits beside refinancing strain, though: CRE Daily has reported a refinance gap of $6.8 billion for multifamily after the September rate hike.
Why It Matters
Growth across every major capital source means liquidity has not dried up, even as borrowers face higher costs. Commercial Property Executive read the numbers as a finance market steadily widening its capacity for investment and refinancing.
A bigger debt stack also raises the stakes for upcoming maturities. CRE Daily has reported that the maturity wall shrank to $875 billion, even as higher rates make refinancing harder, a point Commercial Property Executive also raised.
What’s Next
MBA updates the series every quarter, so the Q3 report will show whether banks, agencies and CMBS investors keep adding at this pace and whether banks hold their 38% share.
