Periods when inflation is low and few people are paying attention to central banking are happy times.

In Canada, these are not happy times. Inflation is high and the Bank of Canada is under scrutiny. Unhappiness will increase as the bank increases its policy interest rate to get inflation back to its 2-per-cent target, because tighter monetary policy will pinch consumers and businesses before it reduces inflation.

That poses risks – notably that politics will interfere with monetary policy. Since politicians don’t like monetary-policy pinches, interference could result in inflation staying higher for longer. Odd as it may seem when the Bank of Canada has already let inflation get so far above target, continuing to protect the institution’s independence is the most promising route back to low inflation.

Criticism of the bank’s policies over the past 18 months or so is fair. After all, the year-over-year increase in the consumer price index was 6.7 per cent in March – more than twice the top of the 1-to-3-per-cent band around the bank’s target. This outcome is a result of the bank’s reaction to the pandemic, however well calibrated to the initial emergency, staying too strong for too long.

The bank lowered the overnight rate quickly when the pandemic started, and started buying financial assets, including longer-term Government of Canada bonds – the program known as quantitative easing (QE) – to ensure that liquidity was cheap and readily available when the economy looked likely to seize up entirely. Such moves prevented the damage COVID-19 was inevitably going to do to the economy from multiplying.

However, the Bank of Canada, like many other central banks, misjudged the extent to which further stimulus was needed once the worst of the crisis was over.

They took their cue from the period after the 2008-2009 financial crisis and recession, when central banks kept their policy interest rates extremely low for more than a year, and many pursued QE programs to the point where their balance sheets were many times bigger than before the crisis. Despite this monetary stimulus, inflation remained low.

A key difference this time around is that, in addition to continued monetary stimulus, governments in Canada have continued to run huge deficits focused on consumption long after the crisis period was over. That boosted demand in a world where supply cannot keep pace because of snarled supply chains, Russia’s invasion of Ukraine and damage to productive capacity from two years of lockdowns.

Staying too strong for too long was a mistake, especially while massive fiscal stimulus continued – but the Bank of Canada was not alone in making it. The U.S. Federal Reserve, the Bank of England, the European Central Bank and many others did likewise, and their currencies are also declining in value.

Prior to this pandemic episode, the Bank of Canada had a superb record of controlling inflation. Between December, 1995, and December, 2019, inflation averaged 1.9 per cent and was inside the 1-to-3-per-cent target band almost 80 per cent of the time. That record not only reflects adept monetary policy, but also the advantages of the Bank of Canada being independent from the government: the ability to adjust policy in response to inflation rather than following other imperatives, such as keeping interest rates low in advance of elections or buying government debt when other lenders will not.

The need for monetary-policy independence will be stronger than ever in the months and years ahead. To tame inflation, the bank recently raised the overnight rate by 50 basis points – the first hike greater than 25 basis points in over two decades. It is also reversing QE by allowing the bonds it owns to mature and not buying new ones, even while the federal government continues to issue new debt. Higher interest rates will pinch and put pressure on the federal budget. The bank must be free to continue to raise its policy rate and manage its balance sheet without political interference.

Looking further ahead, digital currencies of various kinds may become serious competitors to currencies issued by central banks, including the Bank of Canada. While there are potential benefits to these competitors, there are also dangers to the bank’s ability to conduct its monetary policy. A central-bank digital currency linked to the loonie is one way in which the bank can encourage Canadians to use our own dollar rather than, for example, a cryptocurrency linked to a foreign currency.

But if threats to the bank’s independence hurt confidence in the Canadian dollar, either its current or a future digital form, the bank’s ability to provide a currency with a predictable purchasing power could erode – further undermining inflation control.

The Bank of Canada has some heavy lifting to do. In the near term, it must get inflation back to target. In the longer term, it needs to keep the Canadian dollar attractive against existing and emerging rivals. Independence will help the bank provide Canadians with the reliable currency they want.
