The following two charts represent the yield on 10- and 30-year U.S. treasury bonds.
Treasury bonds are used to price mortgage bonds. Thirty-year mortgage rates, around 6.8%, are still below the highs seen in 2023, meaning that the mortgage spread over treasuries has compressed substantially. But the trend in log term treasury and mortgage rates seems to be on the rise.
Today’s 30-year bond auction was somewhat weak, and demonstrated that investors are demanding substantial compensation to take on 30-year duration. The yield on the 30-year bond auction today was 5.216%.
