Exam code: 0455 & 0987
The role and importance of central banks
A central bank is the main financial institution of a country, responsible for managing the nation’s currency, money supply and interest rates
The Central Bank plays a vital role in maintaining stability in the financial system
The policy tools at their disposal help to meet government economic objectives and create economic growth

What do central banks do?
1. Implement monetary policy
Monetary policy is the adjustment of interest rates and the money supply so as to influence total demand and meet the inflation target
2. Banker for the government
The government sets the annual budget but it is the Central Bank that manages the tax receipts and payments
In 2022 there were 5.7 million public sector workers in the UK who had to be paid by the Central Bank each month
3. Banker to the commercial banks – lender of last resort
Commercial banks are able to borrow from the Central Bank when they run into short-term liquidity issues
Without this help, they might go bankrupt leading to instability in the financial system - and a potential loss of savings for many households
4. Regulation of the banking industry
Regulation is when the government sets rules or laws to control the way consumers and producers behave in a market
The high level of asymmetric information in financial markets requires that commercial banks are regulated in order to protect consumers
