Lacy Hunt and Van Hoisington write,
Presently the inflation picture is most favorable to bond yields. The year-over-year change in the core personal consumption expenditures deflator, an indicator to which the Fed pays close attention, stands at a record low for the entire five plus decades of the series
True.
Over the past year, the Treasury bond yield rose as the nominal growth in GDP slowed. The difference between the Treasury bond yield and the nominal GDP growth rate (Chart 4) is important in two respects. First, when the bond yield rises more rapidly than the GDP growth rate, monetary conditions are a restraint on economic growth. This condition occurred prior to all the recessions since the 1950s, as indicated in the chart. This condition also signaled the growth recessions in 1962 and 1966-67. Second, the nominal GDP growth rate represents the yield on the total economy
True.
But then I downloaded from the Fred database the 10-year Treasury rate and the level of nominal GDP. I took the three-year average of nominal GDP growth rate, and I subtracted it from the 10-year rate, to get a rough measure of the differential between the 10-year rate and the growth rate of nominal GDP. From 1963 to present, this differential averages -.18. A super-simplistic model is that the nominal interest rate should revert to this average differential. So, if nominal GDP growth is 6.25 percent and the average differential applies, the nominal interest rate should be 6.07 percent.
For the latest three years, ending in Q1 of this year, nominal GDP growth has averaged 3.85 percent. Using the super-simplistic model of the nominal rate, it should now be 3.67 percent. In fact, it is now 2.52 percent.
Hunt and Hoisington are betting that the nominal interest rate is going to fall, but when I look at the same GDP data they do, I think it ought to be higher than it is now.
