Regulators Say Rising Rates Could Ding Life Insurers' Mortgage Investments

Life insurers have about $1 trillion invested in mortgages and mortgage-backed securities.

Higher interest rates should improve yields on new mortgages and mortgage-backed securities, but they could hurt the value of mortgages and mortgage-backed securities already in life insurers’ investment portfolios.

Jennifer Johnson and Michele Wong, analysts at the National Association of Insurance Commissioners’ Capital Markets Bureau, gave that assessment in a new analysis of the impact of rising interest rates on insurers’ investments.

What It Means

The new, higher rates could have different effects on some life insurers than on others, depending exactly on how the insurers invest in mortgages and mortgage-backed securities.

That could increase the gap between the most attractive life and annuity products and the least attractive products and make the advice of a financial professional who can tell the difference more important.

Corporate Bond Rates

The typical rate on an investment-grade corporate bond was 5%. last month.

That was down from 5.5% in December 2022, and down from 7.9% in January 2000. But it was up from a typical rate of less than 3% from January 2010 through January 2022, according to Federal Reserve Bank of St. Louis data cited by Johnson and Wong.

Life Insurers’ Mortgage-Related Holdings

Life insurers ended 2021 with a total of about $5.2 trillion in cash and investments.

They held $640 billion in mortgage investments and $420 billion in commercial and residential mortgage-backed securities.

Negative Effects

One way rising rates could hurt life insurers and other mortgage investors is by making taking out mortgages to buy property less attractive, which reduces mortgage loan volume, the analysts say.

“In turn,” the analysts add, “home and commercial property purchases could begin to decline.”

Higher rates could also hurt the market values of the real estate backing the mortgage loans.

That could affect life insurers’ lenders’ appeal to investors by increasing “loan to value” ratios, the analysts add.
