The Bank of England is holding a “Festival of Mistakes” this week, celebrating lessons learnt from financial disasters of the distant past. Some would argue that they, and their counterparts at other central banks, should focus on more recent errors.
Advanced economies are experiencing the most acute — and most enduring — outbreak of inflation for a generation. Yet almost all rate-setters failed to spot the degree to which price pressures would ratchet up — and stick around, despite record amounts of monetary and fiscal stimulus.
Most of the Federal Reserve’s rate-setters failed to foresee that inflation would ever rise, and then overestimated the speed of its decline. Economists at the BoE and the European Central Bank underestimated the scale and persistence of inflation. Across the world, poor forecasts have contributed to central bankers failing to do their main job: maintaining price stability.
