Another opinion said that the notion of monetary policy is the government’s efforts made through the Central Bank to control the macro economy so that conditions are better by regulating the amount of money in circulation and improving people’s welfare.

In Indonesia, this monetary policy is carried out through Bank Indonesia as a monetary authority to direct the national economy. In its implementation, monetary policy has a relatively shorter time lag compared to fiscal policy because Bank Indonesia does not need permission from the Parliament and cabinet in implementing monetary policy.

Monetary Policy Types and Indicators

Monetary policy that applies in Indonesia can be divided into two types, the following explanation;

  1. Contractive Policy, which is a policy that limits the amount of money in circulation due to high inflation.
  2. Expansive policy, which is a policy that increases the money supply in which the aim is to increase people’s purchasing power when the economy is declining.

To determine the success rate of monetary policy, the Central Bank uses 3 indicators, namely;

  1. Money SupplyMonetary Targeting )
  2. Targeting ExchangeExchange Rate Targeting )
  3. Target InflationInflation Targeting )

The following explanation is in the table:

Indicator Definition Advantages Deficiency
Money Supply ( Monetary Targeting ) Establish growth in the amount of money circulating in the community as an intermediate target It is possible to implement an independent monetary policy so that the central bank can focus on controlling inflation > Its application depends on the stability of the relationship between the monetary amount and the final target (inflation).

> Difficult to understand by ordinary people.

Targeting Exchange ( Exchange Rate Targeting ) Establish and adjust the value of the domestic currency against the currencies of large countries that have low inflation rates. > Can reduce inflation.

> Simple and easy for people to understand.

> Exchange rate targeting is determined by rules that discipline monetary policy

> Prone to speculators.

> Turmoil in a country can directly impact the domestic economy

Target Inflation ( Inflation Targeting ) Determination of the medium-term inflation target and commitment to achieve price stability as a long-term goal. > Simple and very clear achievement targets.

> Does not depend on the stability of the relationship between monetary quantities and the final target (inflation).

> Improve central bank accountability

> Monetary policy can be focused on achieving stability in the domestic economy

Signals to achieving targets are not as fast as previous approaches

Example of  Monetary Policy

The following are some examples of monetary policies that have been carried out in Indonesia:

  1. Bank Indonesia (BI) auctioned its certificates, or it could be by buying securities on the capital market
  2. BI can reduce interest rates when economic conditions are in line with expectations. And conversely, BI can raise interest rates when it wants to limit economic activity so that money circulation is reduced.
  3. When the economy goes into a recession, the circulation of money will be increased so that economic activity increases. One example is buying securities.
  4. When inflation occurs, BI can reduce the circulation of money in society by selling securities, thereby reducing excessive economic activity.
