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.

"They had horse blinders on. They didn't want to entertain any talk of stable or upside risk to inflation in response to massive stimulus around the world, government and monetary," said Derek Holt, head of capital markets economics at Scotiabank in Toronto. "I think they had that evidence even as 2020 unfolded," yet held onto emergency programs for another year, and discounted an initial rise in inflation as transitory.

The result: Over little more than a week the Fed has whipsawed financial markets with a 75-basis-point interest rate increase, its first hike of that size since 1994; the European Central Bank scrambled towards new emergency plans to control government bond spreads; the Swiss National Bank approved an unexpected rate hike; Bank of England forecasts hinted at a developing stagflation; and Bank of Japan Governor Haruhiko Kuroda was forced to apologize after stinging criticism of remarks that households had become "accepting" of higher prices.

Kuroda's predicament was emblematic.

Inflation in Japan crept just over 2 per cent on an annual basis in April, low compared to the more than 8 per cent increases in consumer prices seen recently in the United States, for example, and effectively meeting the BOJ's 2 per cent target after decades of concern about the opposite problem of deflation.

Yet the notion of households accepting higher prices proved taboo, something that central bankers and elected officials across the world are fast relearning after a generation when prices were held down by a variety of forces, including globalization, that the pandemic may have eroded.

"Every one of these central banks is operating in some kind of risk management framework and really since the (2007-2009) financial crisis ... the race was who was going to outease the other" in order to sustain growth and jobs in a low and even falling price environment, said Ed Al-Hussainy, a senior rates analyst with Columbia Threadneedle. "Now that is going in reverse ... The risk of error has shifted to the other side of the street," in the form of inflation that threatens to stay higher and take public wage and price expectations with it.

BLINDSIDED

Critics say the central banks themselves are to blame for keeping interest rates too low for too long, and printing too much money for the economy to absorb - particularly an economy in which the supply of goods and services suffered its own setbacks.

Central bankers argue that much of the current price shock is beyond their control, with inflation made more intense and persistent by events such as the Ukraine war or the still uncertain return of China to its place in the global goods supply chain.

Whatever the causes, the impact has been felt acutely by households. Blindsided by rising food and energy prices they were told would be temporary, faith has begun to erode that central banks will hit their typical 2 per cent inflation targets any time soon - a worrisome development that's begun shaping central banks' own reactions.

After the Fed unveiled its large rate hike on Wednesday, Chair Jerome Powell was blunt in tying the historical action to fears the Fed was losing the battle in shaping public expectations about inflation.

Some economists downplay such expectations, measured in surveys of households, as being overly sensitive to things like gas and food prices that are excluded from the "core" inflation trends typically given importance in setting monetary policy.

But "headline inflation is what people experience," Powell said in a news conference after the policy decision. "They don't know what 'core' is. Why would they? They have no reason to. So expectations are very much at risk" the longer headline inflation stays elevated.

"Central banks have persuaded themselves that longer-term inflation expectations were the whole story," and took comfort from surveys showing households expect inflation to fall years into the future, said Karen Dynan, a nonresident senior fellow at the Peterson Institute of International Economics and a professor at Harvard University. But "people look backwards too, and there is inertia. They think about what changes in wages and prices help them keep up," and begin demanding them in ways that can drive prices and wages higher.

If households are getting less trustful, politicians are taking note as well.

Bank of Canada Governor Tiff Macklem has faced calls for his removal, and the central bank has promised a public vetting this summer of its mistaken inflation forecasts. Australia is planning a review of central bank operations after the Reserve Bank of Australia's misread of inflation led it to start rate increases in May after saying until late last year that rises in borrowing costs were unlikely until 2024.

Powell next week will testify twice before lawmakers in the U.S. Congress as part of his regular biannual monetary policy updates. The sessions will likely focus on the threat of high inflation and what's become the central question as interest rates spike and key markets start to slow: How bad will it get?

Maintaining central bank independence "was easier when central banks were making progress - not when a situation is deteriorating," said Vincent Reinhart, a former Fed official who is now the chief economist at Dreyfus and Mellon. He noted that the collective missteps have occurred during "the relatively easier part of the tightening spell," when rates are rising from near zero and the price to be paid in terms of slower economic growth and higher unemployment is not yet apparent.
