Backdrop

A mortgages is ” “a loan used either by purchasers of real property to raise funds to buy real estate, or alternatively by existing property owners to raise funds for any purpose while putting a lien on the property being mortgaged” (Wikipedia).

About 90% of all homebuyers choose 30-year fixed-rate loans, i.e. a mortgage whereby the interest rate is locked in for 30 years. Other popular choices are 15-year fixed-rate loans, or loans with adjustable rates, whereby rates can change once every 5 years (also known as “5/1 ARM”).

Why It Matters

Roughly 60% of homes purchased in the US are financed through conventional mortgages. The importance of the mortgage market becomes apparent when realizing that total mortgage debt outstanding in the United States in early 2021 was just under 17 trillion US dollar, or roughly 80% of US GDP (about 21 trillion US dollar).

Over the coming months, mortgage rates can be expected to rise, as central banks normalize their monetary policy stance. Very rapid rate increases could be disruptive to the housing market, and may hurt affordability.
