How should investors assess the equilibrium real rate of interest?
Later this month it seems likely that the Fed will raise rates once more, continuing its progress towards the normalization of interest rates. But what is “normal”? As the economy itself normalizes, the question of what is the “normal” rate of interest becomes more pressing. Pictet Wealth Management is warning that markets may be too complacent - in which case a "serious adjustment" could be forthcoming.
Economists use a number of different terms to describe the concept of "normal" interest rates: “equilibrium real rates”, the “natural rate” of interest, the “Wicksellian rate” or R-star. Janet Yellen describes this “neutral rate” as the value of the Fed Funds rate that would be neither expansionary nor contractionary. In previous times the equilibrium real rate was thought of as a constant – “normalization” would reflect a reversion to the long-run average (around 2%). Today, the concept of R-star as a constant is in doubt.
