Monetary Policy

Monetary Policy

Monetary policy is the manipulation of monetary variables such as money supply, interest rate and the exchange rate to influence aggregate demand to achieve macroeconomic objectives such as economic growth, price stability, and full employment.

The Central Bank and Monetary Policy Tools

  • The Monetary Authority of Singapore (MAS) is responsible for formulating and implementing Singapore's monetary policy.

  • The MAS utilizes two primary tools:

    • Exchange Rate Management:

      • Singapore maintains a managed float system, targeting a basket of currencies.

      • MAS intervenes in the foreign exchange market by buying or selling Singapore dollars (SGD) to influence its exchange rate.

    • Interest Rates:

      • MAS influences short-term interest rates through Open Market Operations (OMO).

      • Buying government bonds injects money into the banking system, lowering interest rates.

      • Selling bonds withdraws money, raising interest rates.

Impact of Monetary Policy on Aggregate Demand (AD)

  • Expansionary Monetary Policy:

    • Exchange Rate Depreciation:

      • A weaker SGD makes exports cheaper, encouraging foreign demand and boosting economic activity.

      • However, it can also lead to imported inflation.

    • Lower Interest Rates:

      • Cheaper borrowing encourages businesses to invest and consumers to spend, increasing aggregate demand (AD) and economic growth.

  • Contractionary Monetary Policy:

    • Exchange Rate Appreciation:

      • A stronger SGD makes imports cheaper, potentially lowering inflation.

      • However, it can also make exports more expensive, hindering economic growth.

    • Higher Interest Rates:

      • More expensive borrowing discourages investment and spending, reducing AD and inflationary pressures.

Impact of Monetary Policy on Living Standards

  • Economic Growth: Expansionary policy can promote economic growth, potentially leading to higher incomes and improved living standards. However, excessive inflation can erode purchasing power.

  • Price Stability: Maintaining price stability protects the value of savings and ensures a stable environment for economic activity.

  • External Competitiveness: Exchange rate management plays a crucial role in maintaining Singapore's external competitiveness. A weaker SGD can boost exports but raise import costs. Conversely, a stronger SGD can control inflation but might dampen export competitiveness.

Considerations for Singapore

  • Small Open Economy: Monetary policy needs to be cautious due to Singapore's openness. Changes in interest rates can affect capital flows.

  • Inflation Targeting: The MAS focuses on maintaining price stability through inflation targeting. This ensures a stable environment for long-term economic growth.

  • Policy Coordination: Monetary policy often complements fiscal policy to achieve macroeconomic goals.

Evaluating Monetary Policy

  • Analyze the effectiveness of monetary policy in achieving its objectives. Consider time lags and potential spillover effects on other economies.

  • Evaluate the trade-off between economic growth and price stability in the context of Singapore's monetary policy framework.
