Role of Money, Commercial vs Central Banks & Interest Rate Transmission

1

Barter vs The 4 Functions of Money

Barter (swapping goods directly without money) fails in modern economies because it requires a 'double coincidence of wants' (finding someone who has what you want and wants what you have). Money solves this by fulfilling four functions: 1. Medium of exchange. 2. Measure of value (unit of account). 3. Store of value. 4. Method of deferred payment (enabling credit and loans). Note: Credit/debit cards and cheques are not money themselves; they are payment mechanisms that transfer money held in bank deposits.

Characteristics of Good Money

To function effectively, money must be: 1. Acceptable (everyone trusts and accepts it as payment). 2. Durable (notes/coins do not wear out quickly). 3. Portable (easy to carry or transfer electronically). 4. Divisible (can be split into smaller units like pence to give exact change). 5. Scarce / Limited in supply (maintained by the Central Bank so it holds its value) and Difficult to counterfeit.

Role of Commercial Banks & Building Societies

Financial intermediaries that channel funds from savers (who have surplus money) to borrowers (who need funds). Functions: 1. Accepting deposits safely. 2. Lending money to households (mortgages, personal loans, overdrafts, credit cards) and firms (business loans, commercial mortgages). 3. Handling payments (BACS, contactless cards, direct debits, foreign currency exchange). Commercial banks are owned by shareholders and aim to maximise profit; Building Societies (e.g., Nationwide) are 'mutual' institutions owned by their customer members.

Role of the Central Bank (The Bank of England)

The UK's central bank has four primary responsibilities: 1. Implementing Monetary Policy: its Monetary Policy Committee (MPC) sets the official Bank Rate (base interest rate) every 6 weeks to achieve the government's inflation target of 2% CPI. 2. Banker to the government (managing national debt and government accounts). 3. Banker to the commercial banks and 'Lender of Last Resort' (stepping in with emergency liquidity if a commercial bank risks collapsing, preventing a bank run and maintaining financial stability). 4. Issuing legal tender banknotes and regulating the financial system.

Interest Rate Transmission to Consumers (Saving & Borrowing)

When the Central Bank increases interest rates: 1. The reward for saving increases, so households save a higher proportion of their income and consume less today. 2. Cost of borrowing increases -> consumers take out fewer loans for cars, furniture, and holidays. 3. Variable-rate mortgage repayments rise -> homeowners have less discretionary disposable income left after paying their mortgage, reducing consumer spending. (The exact opposite happens when interest rates are cut).

Interest Rate Transmission to Business Investment

Investment is spending by firms on capital goods (new machinery, technology, factories, and vehicles) to increase future productive capacity and productivity. Most investment is funded either by borrowing from banks or using retained profit. When interest rates rise, the cost of repaying business loans increases (reducing the expected net return on investment) and keeping retained profits in a bank account earns higher interest, so business investment falls.

1. Q1

   Explain why money is essential for specialisation and trade in a modern economy, referring to the four functions of money. [4 marks]

   Check Mark Scheme

   Click “Check Mark Scheme” to compare your answer, 1. Medium of exchange: Without money, workers who specialise in one narrow job (like teaching or making car parts) would have to barter, which requires a slow and difficult 'double coincidence of wants'; money is universally accepted so workers can exchange their wages for any good or service [1 mark]. 2. Measure of value (unit of account): Money provides a common unit (£) to express the price of every product and the value of different labour skills, allowing consumers and firms to compare costs easily [1 mark]. 3. Store of value: Money does not rot like agricultural goods, allowing workers and firms to save their earnings safely in a bank to spend or invest in the future [1 mark]. 4. Method of deferred payment: Money allows businesses and households to sign contracts, buy raw materials on trade credit, and take out mortgages/loans today with a clear agreement on how much will be repaid in the future [1 mark].

2. Q2

   Compare the main functions and objectives of a Commercial Bank (such as Barclays or Santander) with those of a Central Bank (the Bank of England). [4 marks]

Objectives: A commercial bank is a private-sector PLC owned by shareholders whose primary objective is profit maximisation, whereas the Bank of England is a state-owned public institution whose primary objective is macroeconomic and financial stability (keeping CPI inflation at 2%) [1 mark]. 2. Customers: Commercial banks serve individual households and private businesses on the high street/online, whereas the Central Bank serves as the banker to the UK Government and to the commercial banks themselves [1 mark]. 3. Day-to-day functions: Commercial banks accept savings deposits from the public, process card/cheque payments, and grant mortgages and business loans [1 mark]. 4. Monetary policy & regulation: The Bank of England sets the national Base Interest Rate, issues legal tender banknotes, regulates commercial banks' risk-taking, and acts as the 'lender of last resort' to prevent bank collapses [1 mark].

3. Q3

   Suppose the Bank of England increases the Base Interest Rate from 2.0% to 5.25% to control high inflation. Evaluate the impact of this interest rate increase on UK households and businesses. [6 marks]

Negative impact on borrowers & mortgage holders: Commercial banks pass the higher base rate on to borrowers; households with variable-rate mortgages (or whose fixed-rate deals expire) face hundreds of pounds in extra monthly mortgage interest payments, reducing their disposable income and living standards [1 mark]. 2. Reduced consumer spending on durables: Higher interest rates on car loans and credit cards make borrowing much more expensive, causing households to delay buying houses, cars, and furniture [1 mark]. 3. Positive impact on savers: Households with large cash savings in bank accounts (often older, wealthier retirees with no mortgage) benefit from a higher interest reward on their deposits, increasing their interest income [1 mark]. 4. Negative impact on businesses (Falling demand & Higher costs): Businesses selling income-sensitive or credit-funded goods (like housebuilders, car dealerships, and restaurants) suffer a fall in sales revenue, while firms with existing bank overdrafts and loans face higher fixed interest costs [1 mark]. 5. Reduced business investment: Higher borrowing costs reduce the profitability of capital investment projects, causing firms to cancel plans to buy new machinery or open new stores (slowing long-run economic growth and potentially increasing unemployment) [1 mark]. 6. Evaluation (Time lags & Fixed rates): However, the impact is uneven and delayed: over 80% of UK mortgage holders are on 2-to-5-year fixed-rate mortgages (so they are shielded until their fix ends), and businesses that fund investment from retained profits rather than bank loans are less directly affected by loan rates [1 mark].

4. Q4

   Explain why the Financial Conduct Authority (FCA) and the Bank of England regulate commercial banks, and explain what could happen to the wider economy if a major commercial bank were allowed to fail. [4 marks]

Commercial banks hold the life savings of millions of households and process daily payments for businesses; without regulation, banks might take excessive risks by lending to borrowers who cannot repay (as happened in the 2008 global financial crisis) [1 mark]. 2. If a major bank collapsed and savers lost their money, panic would spread and cause a 'bank run' on other healthy banks as millions of customers rushed to withdraw their cash simultaneously [1 mark]. 3. Bank failures would freeze the credit market ('credit crunch'): businesses would be unable to get loans or overdrafts to pay staff and suppliers, and homebuyers could not get mortgages [1 mark]. 4. This collapse in consumer and business confidence, spending, and investment would trigger a severe economic recession and mass unemployment, which is why the Bank of England acts as 'lender of last resort' and guarantees deposits up to £85,000 [1 mark].
