Role of Central Banks

Key Functions of a Central Bank

Central banks such as the Bank of England are responsible for maintaining monetary and financial stability.

Implementation of Monetary Policy

Central banks are responsible for setting interest rates and quantitative easing in order to meet the government's inflation target and support economic growth.

In the UK, the Bank of England's Monetary Policy Committee (MPC) sets interest rates to meet the government's inflation target of 2% CPI.

• If inflation is above target, the central bank may raise interest rates to reduce spending and borrowing, which can help bring inflation down.
• If inflation is below target, the central bank may lower interest rates to encourage spending and investment, which can help increase inflation.
• If inflation is below target, and the interest rate is already at the zero lower bound, the central bank may use quantitative easing to stimulate the economy.

Banker to the Government

Central banks act as the government's banker, managing the government's accounts and issuing government debt.

This includes issuing government bonds, managing the national debt, and providing advice on fiscal policy and economic conditions.

Banker to the Banks - Lender of Last Resort

Central banks act as a lender of last resort to commercial banks and other financial institutions in times of financial stress.

This means that if a bank is facing a liquidity crisis and cannot borrow from other banks, the central bank can provide emergency funding to prevent the bank from failing and causing wider financial instability.

Regulation of the Banking System

Central banks are responsible for regulating the banking system to ensure that banks operate safely and soundly.

The Bank of England has two regulatory roles:

• Prudential Regulation Authority (PRA) - setting rules and standards for banks to ensure they have sufficient capital and liquidity to withstand shocks. For example, the PRA sets minimum capital requirements and conducts stress tests to assess banks' resilience to adverse economic conditions.
• Financial Policy Committee (FPC) - monitoring the financial system as a whole to identify and mitigate risks that could threaten financial stability. For example, the FPC may recommend macroprudential measures such as loan-to-value limits to prevent excessive credit growth and asset bubbles.
