The average 30-year fixed rate mortgage (FRM) rate remained level at 7.19% in the week ending September 22, 2023. The average 15-year FRM rate was also roughly flat at 6.54%.  

Watch for FRM rates to soon slip in the short term as 10-year T-note investors react with inverse variation to the Fed’s moves to knock down excess inflation. Then, FRM rates will resume their long-term upward trend which, in 2013, introduced a half-cycle of some 30 years of rising FRM rates. 

The 2020-2021 period of the Pandemic Economy saw FRM rates artificially reduced to their lowest rates ever. FRMs will not see those lows in the 2023 recession. 

When the pandemic set in, the average 30-year FRM rate had risen to almost 4.0% which slowed price increases by reducing the amounts buyers were able to borrow. Today’s post-pandemic rise in the FRM to 7.19% inflicts a further reduction in buyer purchasing power — which controls property pricing. This forces buyers dependent on mortgage funds to consider a home in a lower price tier (unlikely), or simply wait out the drop in seller asking prices to match their reduced purchasing power.

Fundamentally, the setting of FRM rates is tied to the treasury bond market, as are capitalization (cap) rates. The 30-year FRM rate moves in tandem with the 10-year Treasury Note rate. Historically, the risk premium spread between the 10-yr T-Note rate and the 30-yr FRM rate is 1.5%. The spread is far greater for cap rates. 

However, on September 22, 2023, the 10-yr T-Note rate is 4.43%. Thus, the spread between the 10-year T-Note and 30-year FRM rate is a high 2.76%, well above the historical risk premium spread of 1.5%. Today’s generous spread indicates lenders continue to pad their risk premiums in anticipation of future rate increases — and foreclosures due to defaults.

The average monthly rate on adjustable rate mortgages (ARMs) continues to edge higher in September 2023, averaging 7.15%. The interest rate on the ARM is higher than the 15-year FRM and essentially level with the 30-year FRM rate. Thus, a riskier ARM is fairly useless to buyers seeking to increase their borrowing capacity.

This inversion in rates has completely eliminated the appeal of ARMs — and the support for home prices ARMs provided before the inversion.

The 5/1 average adjustable rate mortgage (ARM) rate shows the average rate for the first five years after origination. After the initial five-year period, the ARM rate is adjusted annually based on an index figure, such as a certain Treasury Bill rate (which reflects Federal Reserve rate movements) or the London Inter-Bank Offered Rate (LIBOR). Beginning January 2016, the average ARM rate in California is provided by Bankrate.com. Prior to January 2016, the average ARM rate is provided by Freddie Mac’s survey of the Western Region of the U.S.

This index is one of several indices used by lenders as stated in their ARM note to periodically adjust the note’s interest rate. It replaced the LIBOR in 2021, which was found to be manipulated in the years leading up to the 2008 recession and financial crisis. The ARM interest rate equals the SOFR rate plus the lender’s profit margin. The rate is based on overnight borrowing in the U.S. Treasury repo market. The SOFR is produced in a transparent manner and is based on observable transactions, rather than models, and, unlike the LIBOR, is not dependent on bank estimates.
