The spectre of continued weak inflation haunts central bankers. In a recent speech, Governor Stephen Poloz of the Bank of Canada suggests that the absence of inflation has led “some to question whether central banks can still target inflation effectively.” Poloz adopts a very defensive posture and argues that Bank of Canada does understand the “inflation process and retains the ability to guide inflation to our targets over time.”[1]
Here are some of the factors that the Governor says has kept the inflation rate well below target:
Ironically, with the exception of fluctuations in the exchange rate, monetary policy has no real impact on any of these factors cited by the Governor. Each in its own way works through the economy and is essentially immune to changes in interest rates or liquidity in the banking system.
Yet, the Governor Poloz defends inflation targeting arguing that:
In the absence of shocks coming from external factors, we can expect the trend of inflation to be sustainably around the midpoint of the target range when the economy is operating at full capacity and inflation expectations are well anchored on the target. That is why I have said that “home” for the economy is at the intersection of full capacity and 2 per cent inflation.
