Fed Inflation Expectations: Pre-Packaged Baloney

 | Jan 28, 2015 11:28PM ET

Ten-year nominal rates continue to drift back towards the 2012 lows; the U.S. 10-Year Treasury yields only about 1.75% now. But 2015 is so very different than 2012 in terms of the cause of those low rates.

Nominal bonds are like the packaged sandwich you pick up at a gas station: no special orders. You get the meats in the proportions they were put on the sandwich; in the case of nominal bonds you get real yields plus inflation expectations and the nominal yield moves the same amount whether the cause is a change in real yields or a change in inflation expectations. If you buy nominal bonds because you think the economy is growing weak, and you’re right but at the same time inflation expectations rise, then you’re out of luck. You get what’s in the package.

If you look beyond the packaging, to what is making up that 10-year yield sandwich, then the difference between 2015 and 2012 is stark. When 10-year nominal yields were at 1.50% back in 2012, 10-year real yields were at -0.90% and 10-year inflation expectations were around 2.40%. The bond market was pricing in egregiously weak real growth for the next decade, coupled with fairly reasonable inflation expectations. TIPS were clearly expensive at the time, although I argued that they were less expensive than nominal bonds. (In fact, I may have said that they were expensive to everything except nominal bonds).

Today, on the other hand, nominal yields are low for a different reason. TIPS yields, while low, are positive (10-year real yields are 0.13% as I write this) but inflation expectations are very low. So, in contrast to the circumstance in 2012, we see TIPS as very cheap, rather than rich.

One way to look at this difference in circumstance is to study how the proportions of meats in the sandwich have changed over time. The chart below (source: Enduring Investments ) shows the percentage of the nominal yield that is made up of real yields. The percentage which is made up of inflation expectations is approximately 100% minus this number, so one chart suffices. Back in “normal times,” real yields tended to make up 40-50% of nominal yields.
