Fed Seeking to Find Where ‘Phantom Menace’ Neutral Rate Sits

Federal Reserve Chair Jerome Powell and his colleagues are on the march to return ultra-loose monetary policy and accommodative financial conditions to more normal levels. The trouble is, their destination is uncertain and the terrain may be shifting as they forge forward with higher interest rates.

Policy makers differ on what the neutral rate -- the rate that neither restricts nor spurs economic growth -- is and couch it in terms that don’t take account of the current high inflation environment. And they’re unsure what effect their removal of monetary largess will have on fickle financial markets and an economy that have grown accustomed to ultra-low rates.

“I doubt that anyone can say with confidence where neutral is,” said Allianz SE chief economic adviser Mohamed El-Erian.

That increases the risk that the Fed will make a policy mistake, either by raising rates too high and pushing the U.S. into recession or by not increasing them enough and allowing elevated inflation to become endemic.
