Today’s forecast for U.S. Treasury yields is based on the April 21, 2010 constant maturity Treasury yields reported by the Board of Governors of the Federal Reserve System in its H15 Statistical Release reported at 4:15 pm April 22, 2010. The “forecast” is the implied future coupon bearing U.S. Treasury yields derived using the maximum smoothness forward rate smoothing approach developed by Adams and van Deventer (*Journal of Fixed Income*, 1994) and corrected in van Deventer and Imai, *Financial Risk Analytics *(1996). For an electronic delivery of this interest rate data in Kamakura Risk Manager table format, please subscribe via info@kamakuraco.com.

The “forecast” for future U.S. dollar interest rate swap rates is derived from the maximum smoothness forward rate approach, but applied to the forward credit spread between the libor-swap curve and U.S. Treasury curve instead of to the absolute level of forward rates for the libor-swap curve.

Today’s forecast shows 1 month Treasury bill rates peaking at 5.325% in February and March 2018 and the 10 year U.S. Treasury yield at 5.585% on March 31, 2020. Both figures are down about 15 basis points from last week’s forecast.

The negative 19 basis point spread between 30 year U.S. dollar interest rate swaps and U.S. Treasury yields reflects the blurring of credit quality between these two yield curves. The U.S. government is no longer seen as risk free, and 4 of the 8 panel banks that determine U.S. dollar libor are receiving massive government assistance and are, in effect, sovereign credits. For more on the panel members, see www.bbalibor.com. The negative 30 year spread results in an implied negative spread between 1 month libor and 1 month U.S. Treasury yields (investment basis) beginning November, 2014.

**Today’s Kamakura U.S. Treasury Yield Forecast**

The Kamakura 10 year monthly forecast of U.S. Treasury yields is based on this data from the Federal Reserve H15 statistical release:

The graph below shows in 3 dimensions the movement of the U.S. Treasury yield curve 120 months into the future at each month end:

These yield curve movements are consistent with the continuous forward rates and zero coupon yields implied by the U.S. Treasury coupon bearing yields above:

In numerical terms, forecasts for the first 60 months of U.S. Treasury yield curves are as follows:

The forecasted yields for months 61 to 120 are given here:
