Explain how an increase in Bank Rate may lead to a reduction in the rate of inflation

AQA AS-Level Paper 2 June 2024 Insert

Extract B (lines 11–12) states: ‘In response, as inflation rose above the target rate, the Bank of England's Monetary Policy Committee acted by increasing Bank Rate.’ Explain how an increase in Bank Rate may lead to a reduction in the rate of inflation. (10 marks)

The bank rate is the base interest rate set by the Bank of England. This should directly affect high street interest rates, which is the cost of borrowing and reward for saving. Inflation is the rate at which the average price level increases. When the Bank of England increases the bank rate, high street interest rates should also increase. This leads to changes in many components of aggregate demand through the monetary policy transmission mechanism. As there is an increase in the cost of borrowing and an increase in the reward for saving, consumers and businesses are incentivised to save more and borrow less. Consumers reduce spending as saving is now more rewarding. Businesses reduce investment as borrowing money becomes costly but also because they may anticipate lower demand for their goods and services from consumers. Additionally, as interest rates are higher, there is likely to be a movement of hot money into the economy, which leads to an appreciation of the pound. This causes imports to be cheaper and exports to be more expensive, which can lead to the current account deficit worsening. Overall, consumer spending, business investment, and net exports are likely to fall, which causes aggregate demand to fall, causing a fall in the rate of inflation.
