The new abnormal is still with is, and that means that the recent fall in inflation expectations could be signaling trouble ahead… again. Implied inflation, based on the yield spread between the nominal and inflation-indexed 10-year Treasuries, remains tightly linked with the ebb and flow of the stock market and, by implication, the broader economy. That’s an unusual relationship in the grand scheme of financial and economic history, but it’s a relationship that rolls on in the wake of the Great Recession. It’s also a relationship that in recent weeks seems to be anticipating a new round of problems for the economy. (For the theory behind this empirical fact, see David Glasner’s research paper on the so-called Fisher effect.)
