OCR A Level Economics: Financial institutions, markets and borrowing (H460)

This guide covers part of the role of the financial sector in the real economy, as set out in the OCR A Level Economics (H460) specification, Version 3.0 (June 2026), for first assessment in 2021. This is Component 02 macroeconomics, and no part of it carries a separate stage label. All figures are invented and illustrative: Country A and the currency unit (cu) are fictional.

Money creation, interest rate determination, development finance, central banks and regulation are separate topics. This guide covers institutions, markets, borrowing and interest rate differences only.

Pair it with the revision notes and the practice questions. See also the OCR Economics hub, the checklist and the free diagnostics.

1. Retail, commercial and investment banks

The financial sector links savers, who have spare funds, with borrowers, who want to spend more than their income. Banks do this as intermediaries.

• Retail banks serve households and small firms: current accounts, savings, mortgages, overdrafts, cards.
• Commercial banks lend to businesses and take their deposits. Many institutions combine retail and commercial activity.
• Investment banks deal with large firms, governments and investors. They help issue shares and bonds, advise on takeovers and trade securities.

Macroeconomic impact. Retail and commercial lending finances consumption (C) and investment (I), two components of aggregate demand (AD). When lending expands, AD rises. When banks tighten lending, AD falls even if interest rates have not changed. Investment banks raise long-term funds for firms, which supports capital formation and so long-run aggregate supply (LRAS). Their trading also moves asset prices, which affects wealth and confidence.

Banks also borrow short (deposits withdrawable on demand) and lend long (a 25-year mortgage). This makes credit available, but leaves them exposed if depositors withdraw at once.

2. Pension, hedge and insurance funds

These are non-bank institutions that collect money and invest it.

Pension funds collect contributions now and invest them to pay retirement income later. Because liabilities are decades away, they hold long-term bonds and shares, which makes them large buyers in those markets. Suppose a fund holds 2,000m cu and earns 5% a year. Its income is 2,000 × 0.05 = 100m cu. This channels saving into firms’ investment. A fall in asset values can leave a fund unable to meet promised pensions, which would cut the future spending of retired households.

Insurance funds pool the risk of many people. Worked example (invented): an insurer has 1,000 policies. Each has a 2% chance of a claim of 10,000 cu.

Expected claims per policy = 0.02 × 10,000 = 200 cu
Expected claims in total   = 1,000 × 200   = 200,000 cu
Premium charged            = 230 cu
Premium income            = 1,000 × 230    = 230,000 cu
Expected margin           = 230,000 − 200,000 = 30,000 cu

Pooling works because the average claim is predictable even though any one claim is not. Firms can undertake risky activity, such as exporting, because losses are covered. The risk is a correlated event, such as a storm hitting every policy, which breaks the pooling assumption.

Hedge funds raise money from wealthy or institutional investors and pursue high returns, often using borrowed money (leverage) and complex positions. Worked example: a fund has capital of 100 and borrows 400 to hold assets worth 500.

Change in asset values	Change in value	Return on capital
+4%	+20	+20%
−4%	−20	−20%
−20%	−100	−100% (capital wiped out)

Leverage amplifies gains and losses. Hedge funds can help prices adjust, but forced selling by leveraged funds can push prices down further and pass losses to the banks that lent to them.

3. The stock, bond and foreign exchange markets

Stock market. Firms issue shares to raise equity, and shareholders can sell them on the market. A well-functioning market lowers the cost of raising funds, because investors know they can sell later. Macro effects come through the wealth effect and confidence. Suppose households hold shares worth 400m cu and prices fall 20%. Wealth falls by 400 × 0.2 = 80m cu. If consumption falls by 4 cu for each 100 cu of lost wealth (an assumed figure), it falls by 80 × 0.04 = 3.2m cu. Falling prices also make it harder for firms to raise equity, which can hit investment.

Bond market. Governments and firms borrow by selling bonds that pay a fixed coupon and repay a face value at maturity. Bonds can be resold, so the price changes while the coupon stays fixed. The current yield is coupon ÷ price.

Bond: face value 100, coupon 4 per year
Price 100 → yield 4/100 = 4.0%
Price  80 → yield 4/80  = 5.0%
Price 125 → yield 4/125 = 3.2%

Price and yield move in opposite directions. If new bonds pay 5%, buyers will pay only 4 ÷ 0.05 = 80 for the old bond, a fall of 20%. So rising market interest rates cut the value of bonds already held, which hurts pension funds and banks that hold them. Government bond yields also set the cost of public borrowing.

Foreign exchange market. Currencies are traded here, and the price is the exchange rate. It matters for trade and for flows of financial capital. Worked example: a good costs 40 cu in Country A. At 1 cu = 0.80 foreign currency units (fu), it costs 40 × 0.80 = 32 fu abroad. If the cu depreciates to 0.72 fu, the price abroad is 40 × 0.72 = 28.8 fu, a fall of 10%. Exports become cheaper abroad; imports become dearer at home. The effect on the current account depends on elasticities. Large capital inflows can push up the exchange rate; sudden outflows can cause a sharp depreciation.

4. Inter-bank lending

Banks hold reserves and must settle payments with each other every day. Some end the day with surplus funds, others with a shortage. Inter-bank lending lets surplus banks lend, usually short-term (often overnight), to those short.

Worked example: Bank X lends 30m cu overnight to Bank Y at 3.2% a year.

Interest = 30,000,000 × 0.032 × (1/365) = 2,630.14 cu for one night

Roles in the modern economy:

• It spreads liquidity from banks with surplus to banks with a gap, so a temporary shortage does not force a bank to call in loans.
• The inter-bank rate is a benchmark for other interest rates, and it follows the central bank’s policy rate.

The weakness is trust. If banks doubt each other’s solvency, they stop lending or demand a much higher rate. Short-term funding then dries up, and banks cut lending to households and firms. Because banks are connected, one bank’s failure can spread losses to others (contagion).

5. Forms of borrowing

Form	Features	Typical cost and risk
Mortgage	Secured on property, long term	Lower rate; borrower can lose the home
Unsecured loan	Fixed sum, fixed term, no collateral	Higher rate than secured
Overdraft	Borrowing through a current account up to a limit	Flexible; costly if used long
Credit card	Revolving credit up to a limit	High rate on unpaid balances
Pay day lending	Small, very short-term loans	Very high cost when annualised

Mortgage. House 200,000 cu, deposit 20,000 cu, so the loan is 180,000 cu. The loan-to-value (LTV) ratio is 180,000 ÷ 200,000 = 90%. At 4.8% interest-only, monthly interest is 180,000 × 0.048 ÷ 12 = 720 cu. A repayment mortgage over 25 years at 4.8% costs about 1,031 cu a month, total 309,418 cu, of which 129,418 cu is interest. If prices fall 15%, the home is worth 170,000 cu, which is less than the loan. Equity is −10,000 cu (negative equity). If the rate rises to 6.8% on an interest-only loan, payments rise to 1,020 cu, an extra 300 cu a month. Households with large mortgages cut other spending when rates rise.

Unsecured loan. 5,000 cu at 9% over 36 months, reducing balance, costs 159.00 cu a month. Total repaid is 5,723.95 cu, so interest is 723.95 cu.

Overdraft. Borrowing 500 cu for 30 days at 24% a year costs 500 × 0.24 × 30 ÷ 365 = 9.86 cu. It is cheap for a few days and costly if it becomes permanent.

Credit card. A balance of 2,000 cu at 2% a month costs 40 cu in interest. The nominal annual rate is 24%, but compounding gives (1.02)¹² − 1 = 26.8%. With a minimum payment of 60 cu, only 20 cu reduces the debt.

Pay day lending. Borrow 300 cu for 30 days and repay 345 cu. The cost is 45 ÷ 300 = 15% for one month. Annualised simply, this is 15 × 365 ÷ 30 = 182.5%. Compounded, it is about 448%. Lenders point to high default rates and admin costs on small loans. The risk is rolled-over debt.

6. Why interest rates differ: risk and security

There is no single rate of interest. Rates differ across money markets because lenders require compensation for risk (the chance of not being repaid) and for the lack of security (collateral they can seize and sell).

Worked example. A lender wants an expected return of 5% and thinks 4% of borrowers will default.

No security (nothing recovered):
(1 − 0.04)(1 + r) = 1.05  →  1 + r = 1.05/0.96  →  r = 9.375%

Secured (70% of the loan recovered on default):
0.96(1 + r) + 0.04 × 0.70 = 1.05  →  1 + r = 1.022/0.96  →  r = 6.46%

Security cuts the rate needed by about 2.9 percentage points. A longer term, a small loan size and a poor credit history also raise the rate. This explains the pattern in the table of forms above: mortgages are cheaper than unsecured loans, which are cheaper than cards and pay day loans. Government bonds are generally treated as low-risk, so their yield is a low benchmark.

7. Evaluating the financial sector in the real economy

The real economy is the production of goods and services and the jobs and incomes that go with it.

In favour. The sector turns saving into investment, spreads risk, allows consumption smoothing, and helps price capital and currency. Firms that cannot fund projects from profits can grow, which raises potential output.

Against. Credit booms can inflate asset prices, followed by busts that cut AD and employment. Institutions that are big and linked can spread failure. Pay day and card debt can leave households poorer, and funds can go into trading rather than productive investment.

Judgement. The answer depends on whether the sector is channelling funds into productive investment or into asset speculation, on how much leverage there is, and on how much trust holds between institutions. A fair conclusion is that the sector is necessary for growth, but its benefits depend on stable lending and sensible pricing of risk.

Common errors

• Treating all banks as the same. Say what each type does before giving its effect.
• Saying a bond’s price rises when interest rates rise.
• Calling an exchange rate fall a fall in the price of exports at home. Exports are cheaper abroad.
• Giving a one-month pay day cost without annualising it when comparing rates.
• Explaining why rates differ with risk only, and leaving out security.
• Listing effects without a chain of reasoning to AD, AS or employment.
