According to Federal Reserve Governor Christopher Waller on July 6, excessively rigid forward guidance can actually impede the effectiveness of monetary policy rather than enhance it. Waller cited the FOMC's September 2020 forward guidance pledge, which stated rate hikes would occur when inflation rose to 2% and was on track to moderately exceed that level, as a cautionary example. The Fed maintained this guidance unchanged throughout 2021 despite inflation accelerating above 2% and unemployment falling sharply, creating public confusion about the meaning of "for some time."
Economist Mohamed El-Erian, commenting on Waller's remarks, stated that central banks are beginning to reassess their traditionally unwavering commitment to forward guidance. El-Erian attributed this shift in part to incoming Fed Chair Kevin Warsh's intellectual curiosity and reform-oriented approach.
