Edexcel A Level Economics A:复习笔记4.4.3 Role of Central Banks

• Central Banks play a vital role in maintaining stability in the financial system. Additionally, the policy tools at their disposal help to meet Government economic objectives & create economic growth

Central Banks play four important roles in the economy

1. Implementation of monetary policy:  This was covered more fully in Sub-topic 2.6.2
2. Banker to the government: The Government sets the annual budget but it is the Central Bank that manages the tax receipts & payments. In 2022 there were 5.7 million public sector workers in the UK who had to be paid each month
3. Banker to the banks – lender of last resort: Commercial banks are able to borrow from the Central Bank if they run into short-term liquidity issues. Without this help, they might go bankrupt leading to instability in the financial system - & a potential loss of savings for many households
4. Regulation of the banking industry: the high level of asymmetric information in financial markets requires that commercial banks are regulated in order to protect consumers. One of the key regulatory actions to manage the money supply & promote stability in the financial system is the implementation of required reserve ratios. Raising the ratio decreases the money supply in the economy - and vice versa
