Why Mortgage Rates Will Fall

I have read and heard several comments suggesting that the increase in the 30-year Fixed Rate Mortgage (FRM) this year has been a direct result of the increase in the Federal Reserve’s Fed Funds rate (FF).
This is not correct.
As I will demonstrate, the FRM is determined by market forces, and in particular by the extra yield – the “spread” – which investors require when buying pools of mortgages (Mortgage Backed Securities or MBS), as compared with the risk-free yield available with the 10-year Treasury Note (10T) which has the nearest duration to the expected life of a pool of mortgages.
In contrast, the FF is the rate that banks use when setting their Prime Rates. When the FF increases, banks increase their Prime Rates and therefore the interest rate on those loans whose rates are based upon Prime Rates – e.g. credit cards and auto loans.
And we will see that the FRM increased this year long before the Fed started to increase the FF rate.

Mortgage-Backed Securities (MBS)
A conventional mortgage or conventional loan is any type of home buyer’s loan that is not offered or secured by a government entity. Instead, conventional mortgages are available through private lenders, such as banks, credit unions, and mortgage companies.
Most conventional mortgages are packaged into mortgage-backed securities and sold to investors. This allows the bank or originator to use its capital to finance more mortgages.

This chart shows how the two have moved in lockstep over the last 30-plus years:

While the “spread” has mostly been in the 1.5-2% range, it has fluctuated, especially during times of financial stress or uncertainty: (more…)
