The 30-year mortgage rate fell 6 basis points to 4.1 percent. Since the beginning of the year, the 10-year Treasury yield has covered a 22 basis point range. The range of movement for the 30-year has been half that, just 11 basis points.

In a short week following Presidents Day, the 10-year Treasury yield fell about 8 basis points. However, the 30-year mortgage rate rose 1 basis point to 4.16 percent. This week’s survey once again displays the disconnect between mortgage rates and Treasury yields, a result of continued uncertainty.

For the last 46 years, the 30-year mortgage rate has been almost perfectly correlated with the yield on the 10-year Treasury, but not this year. From Dec. 29, 2016, through today, the 30-year mortgage rate fell 17 basis points to this week’s reading of 4.15 percent. In contrast, the 10-year Treasury yield began and ended the same period at 2.49 percent. A year ago at this time, the 30-year FRM averaged 3.65 percent.
