Bond yields affect mortgage interest rates because mortgages are an investment alternative to bonds. Mortgages are somewhat riskier than bonds, making mortgage rates equal to a bond yield plus a premium reflecting mortgages additional risk.
Every time bonds yield increase, mortgage rates go up. Every time bond yields go down, mortgage rates go down, but at a slower pace if compared to pace when rates going up.
An example: In October 2018 a 5-year bond was 2.42%, and the best 5-year fixed mortgage rate was 3.89%. In March 2019 a 5-year bond is 1.55%, and the best 5-year fixed rate is 3.49%. While bond yield dropped 0.85%, mortgage rates dropped only 0.40%. These are the regular best rates, excluding various promotions. This means that fixed-rate mortgages have room to go further down, which is reflected by various unique promotions with rates at 3.20% rangeIf you choose a fixed rate mortgage today, three to six months down the line, you might find that rates are lower.
