Explain how monetary policy works under an inflation targeting regime

Authors Avatar

Monetary Policy aims to regulate the money supply and the interest rates through the Central Bank. In order to do so, it seeks to control inflation as well as to stabilise the currency. The Bank of England, by being ‘operational independent’, can place targets for inflation and set interest rates at the most appropriate level in achieving those targets. This level is placed every month in Monetary Policy Committee’s meetings. Monetary policy is used for both reflating and deflating the economy. Inflation refers to the sustainable increase in the price level within an economy while deflation is the opposite. Inflation targeting, though, is a successful monetary policy regime designed to keep inflation within a desired range. The purpose of this essay is to explain how monetary policy acts under an inflation targeting regime.

To begin with, inflation targeting (IT) policy offers a wide range of benefits.  For example, in Ball and Sheridan, (2003) it is stated that there are targeting locks in expectations of low inflation and therefore the inflationary impact of macroeconomic shocks is reduced. Then, it is said that it is easier for the public to understand and makes monetary policy more transparent. Inflation targeting was first introduced by New Zeland in 1990 and then many countries used this regime. Central Banks set as their only objective the price stability. It makes explicit the failure of money growth control policies where the target is equal to the objective due to the fact that the link between the intermediate and final objectives is uncertain. Any changes to the interest rate target are made in return to different market indicators in order to forecast economic trends as well as to keep the market on track in achieving the defined inflation target. For instance, one simple method of inflation targeting called the  regulates the interest rates with respect to changes in the inflation rate and the output gap. Mishkin, (1999), mentions that recent researches suggested that inflation targeting countries are experiencing both a reduced inflation rate and inflationary expectation.

While monetary policy decisions have an effect on the economy with a time lag, central banks have power over the future inflation rather than the current inflation. As an outcome of this aim, they develop inflation forecasts regularly and publish them. That is the reason of inflation-targeting regime being also commonly called as “inflation forecast targeting”. Through the same path, forecasts’ consistency, inflation target and finally the risk to deviate from the target are made clear to the public. The inflation target is around 2 per cent at an annual rate for Consumer Price Index.
