Monetary Policy & The Role of Central Banks

Introduction

Central banks play a critical role in shaping a country’s economy through their management of monetary policy. Let’s explore what central banks do, why their role matters, and how they influence economic stability.

What Is Monetary Policy?

Monetary policy refers to the actions taken by a central bank to regulate the money supply, interest rates, and credit availability. Its primary goals are to maintain price stability (low and stable inflation) and promote sustainable economic growth.

Key Functions of Central Banks:

• Interest Rate Management:
  • Central banks adjust short-term interest rates to influence borrowing costs for businesses and consumers.
  • Lower rates encourage spending and investment, while higher rates curb inflation.
• Open Market Operations (OMOs):
  • Central banks buy or sell government securities in the open market.
  • Purchases inject money into the economy, while sales absorb excess liquidity.
• Reserve Requirements:
  • Central banks set minimum reserve ratios for commercial banks.
  • Higher reserves reduce lending capacity, affecting money supply.
• Lender of Last Resort:
  • Central banks provide emergency liquidity to banks during financial crises.
  • This prevents bank runs and systemic collapse.

Recent Trends and Challenges:

• Unconventional Policies:
  • After the 2008 global financial crisis, central banks used unconventional tools like quantitative easing (QE) and negative interest rates.
  • QE involved purchasing long-term bonds to lower long-term rates.
• AI and Monetary Policy:
  • Central banks are exploring the use of artificial intelligence (AI) to enhance policy decisions.
  • Singapore’s Monetary Authority has raised caution about AI’s role in shaping monetary policy¹.
