More Recession Talk

Articles regarding the signals emanating yield curve appear in Reuters, CNBC, FoxBusiness, Bloomberg, CNN . Here’s a relevant picture:

The 10yr-2yr spread is approaching zero, so that segment of the yield curve would be closing in on inversion, a sometime precursor to recession.

Inspection of the yield curve today, and at several points in time, suggests that today’s inversion does not apply to a wide segment of curve.

Note that as of today, inversion is only showing up at the 10yr-3yr segment (10yr-7yr segment as of yesterday).

The rationale for inversion serving as a precursor to recession is the idea that lower expected future short rates during recessions drive lower longer maturity rates. In principle, a “cleaner” look at how expected future short rates look relative to the current short rate can be obtained by removing the term premium (presumably driven by inflation risk) for the long maturity. In Figure 3, I show the spreads adjusted by DKW estimated inflation risk premia.

When the 10 yr-3 mo spread is purged of the term premium on the 10 year Treasury, then in principle that variable measures the expected short term interest rates over the next 10 years relative to the current 3 month yield. This is what the unadjusted and adjusted 10yr-3mo spread looks like over the past 3 decades.

Note deep inversions of the adjusted series typically precede recessions.

We don’t have a 2 year inflation risk premium estimate so as to be able to adjust the 10yr-2yr spread (the above calculation assumes the 3 month Treasury risk premium is nil). However, what is true is that the 10yr-2yr spread taking off the 10 year inflation risk premium had not yet inverted as of end-February (0.6 ppts adjusted vs. 0.39 ppts unadjusted).
