Has the equilibrium level of real interest rates actually risen?
Core argument: The equilibrium interest rate cannot be observed and must be estimated, with the NY Fed's estimate indicating underlying rates remain very low while the Richmond Fed's indicates they have been rising; the author judges the NY Fed estimate more robust for now.
The underlying level of interest rates cannot be observed but must be estimated. There are two well-known estimates. One, from the NY Fed, suggests that underlying interest rates are still very low, while the other, from the Richmond Fed, suggests that they have been rising recently. My reading of this is that the estimate from the NY Fed – at least for now – appears more robust. Low equilibrium interest rates have important implications. Let me conclude by mentioning at least two of them. If underlying equilibrium real interest rates had risen, monetary policy would not be tight right now and would explain why we have not yet experienced a recession. On the other hand, if r* has not risen, monetary policy is tight. I’m leaning towards the latter. I think the economy has been amazingly resilient because people saved a lot coming out of the pandemic, coupled with a very expansionary fiscal policy that is also supporting growth, not that monetary policy is not tight. Second, if underlying real interest rates are low, interest rates should fall when inflation is under control and monetary policy rates are lowered. Perhaps interest rates will not become quite as low as before the pandemic (e.g. negative interest rates in Europe), but should be significantly lower than today.
