Global central bankers, who shared the limelight for skirting a pandemic-driven depression with quick action two years ago, are now stumbling through the aftermath as they try to quell an inflation surge none predicted or have been able to forestall.

If their response to the economic crisis triggered by the pandemic seemed bold and forward-looking, with its laundry list of new programs and massive monetary stimulus, the last few months have been an erratic, even awkward phase of failed forecasts, embarrassing mea culpas, increased political scrutiny and some evidence of lost trust.

Managing inflation is core to a central bank's mission, and from major players like the U.S. Federal Reserve and the Bank of Japan to regional institutions like the Bank of Canada and the Reserve Bank of Australia, recent events have dealt a blow to their credibility as they play catch up with policy and, in the process, raise the likelihood of recession.
