Monetary Authority of Singapore (MAS): Exchange Rate Management

Overview

The Monetary Authority of Singapore (MAS) is the central bank of Singapore. It is responsible for managing the exchange rate of the Singapore dollar (SGD). The MAS uses a managed float system, which means that it intervenes in the foreign exchange market to keep the SGD within a tightly defined band against a basket of currencies.

Objectives of Exchange Rate Management

The MAS's objectives for exchange rate management are to:

• Promote price stability: By stabilizing the exchange rate, the MAS helps to moderate imported inflation and supports the overall stability of the economy.
• Support economic growth: A stable exchange rate provides a favorable environment for businesses and investors, as it reduces uncertainty and facilitates trade.
• Maintain external competitiveness: The SGD's exchange rate against its major trading partners helps to ensure that Singapore's exports remain competitive in international markets.

Exchange Rate Band

The MAS manages the SGD within an undisclosed band that is narrower than ±2% against a basket of currencies. The composition of the basket is kept confidential, but it is believed to include the US dollar, euro, Japanese yen, and other currencies of Singapore's major trading partners.

Intervention Mechanisms

The MAS uses various intervention mechanisms to manage the exchange rate within the prescribed band:

• Foreign exchange market intervention: The MAS buys and sells SGD in the foreign exchange market to influence its value.
• Open market operations: The MAS buys and sells government bonds in the domestic money market to adjust the supply of SGD and affect its exchange rate.
• Verbal intervention: The MAS issues public statements or gives interviews to influence market sentiment and guide the exchange rate.

Data and Sources

The MAS publishes various data and reports on its website, including:

• Daily exchange rates: https://www.mas.gov.sg/statistics/money-and-banking/daily-exchange-rates

Stories and Lessons Learned

Story 1:

In 2020, during the COVID-19 pandemic, the SGD experienced significant volatility against the US dollar. The MAS intervened heavily to stabilize the exchange rate and prevent a sharp depreciation of the SGD.

Lesson Learned: Exchange rate management can help to mitigate external shocks and support macroeconomic stability.

Story 2:

In 2021, the SGD appreciated rapidly against the US dollar, fueled by strong capital inflows into Singapore. The MAS allowed the SGD to appreciate within the upper bound of its band to prevent excessive appreciation and harm to exports.

Lesson Learned: Exchange rate flexibility can be beneficial in times of strong economic growth to support both domestic demand and external competitiveness.

Story 3:

In 2022, the SGD weakened against the US dollar due to rising global interest rates and geopolitical uncertainties. The MAS intervened cautiously to limit the depreciation and prevent a sharp outflow of capital from Singapore.

Lesson Learned: Exchange rate management should balance the need for stability with flexibility to respond to changing market conditions.

Effective Strategies for Exchange Rate Management

• Maintain a strong fiscal and monetary policy framework: This helps to create a favorable economic environment and reduce vulnerability to external shocks.
• Avoid excessive intervention: Excessive intervention can distort the market and reduce the effectiveness of exchange rate management.
• Communicate regularly with the market: Clear and timely communication can help to manage expectations and reduce uncertainty.
• Coordinate with other central banks: Cooperation with other central banks can enhance the effectiveness of exchange rate management.

Common Mistakes to Avoid

• Fixed exchange rates: Fixing the exchange rate against a single currency can lead to loss of monetary policy flexibility and create unsustainable imbalances.
• Undervalued currencies: Undervaluing the exchange rate to boost exports can lead to inflation and loss of external competitiveness in the long run.
• Overvalued currencies: Overvaluing the exchange rate to stabilize prices can hurt exports and economic growth.
• Excessive discretion: Exchange rate management should be based on clear objectives and rules to avoid arbitrary interventions.
