Balance of Payments: Policies and Calculations Revision Notes | GCSE AQA Economics

1. What Is the Balance of Payments?

Every day, the UK buys goods and services from other countries (imports) and sells goods and services to other countries (exports). British consumers buy German cars, Chinese electronics, and American streaming subscriptions. Meanwhile, other countries buy British financial services, pharmaceutical products, and education. The balance of payments is the record that tracks all of these international transactions.

Think of it like a household budget for the entire country. If the UK earns more from selling goods and services abroad than it spends buying from abroad, it has a surplus -- like having money left over at the end of the month. If it spends more than it earns, it has a deficit -- like relying on a credit card. The key question is: is the UK paying its way in the world?

2. The Current Account

The current account is the part of the balance of payments that matters most at GCSE level. It has four main components:

The UK has traditionally had a deficit on trade in goods -- we import more physical products than we export. However, the UK usually has a surplus on trade in services, thanks to the strength of sectors like financial services, insurance, legal services, and education (international students paying tuition fees). Despite this services surplus, the overall current account has been in deficit for decades because the goods deficit is larger.

3. Surplus, Deficit, and Balance

A balanced current account means that inflows exactly equal outflows -- money earned from abroad exactly matches money spent abroad. In practice, this almost never happens. Most countries run either a surplus or a deficit. Germany and China tend to run large surpluses (they export far more than they import), while the UK and USA tend to run persistent deficits.

4. Calculating the Current Account Balance

In the exam, you may be given data and asked to calculate the current account balance. The formula is straightforward:

Current Account Balance = (Export of Goods + Export of Services + Income Inflows + Transfer Inflows) - (Import of Goods + Import of Services + Income Outflows + Transfer Outflows)

If the result is positive, there is a surplus. If negative, there is a deficit.

Worked example: Calculating the Current Account Balance

Use the following data to calculate the current account balance for Country Y. State whether this is a surplus or deficit. Exports of goods: £120 billion Imports of goods: £180 billion Exports of services: £95 billion Imports of services: £60 billion Net income flows: +£10 billion Net transfers: -£5 billion

Method: Calculate each component and sum to find the overall balance.

1. Goods balance = £120bn - £180bn = -£60 billion (deficit) — The country imports more goods than it exports, creating a goods deficit.
2. Services balance = £95bn - £60bn = +£35 billion (surplus) — The country exports more services than it imports, creating a services surplus.
3. Net income = +£10 billion; Net transfers = -£5 billion — Net income is positive (more income earned from abroad than paid out). Net transfers are negative (more paid in transfers than received).
4. Current account = -£60bn + £35bn + £10bn + (-£5bn) = -£20 billion — Sum all components to find the overall position.

Answer: The current account balance is -£20 billion, which is a current account deficit of £20 billion. The country is spending £20 billion more abroad than it is earning from abroad.

5. Reasons for a Current Account Deficit

There are several reasons why a country like the UK might run a persistent current account deficit:

High consumer spending on imports: UK consumers have a strong appetite for imported goods -- electronics from Asia, cars from Germany, food from around the world. When incomes rise, import spending tends to increase faster than export earnings.

Uncompetitive exports: If UK goods and services are more expensive or lower quality than foreign alternatives, other countries will buy less from the UK. High costs of production, a strong pound, or lack of investment in technology can all reduce export competitiveness.

Strong exchange rate: A strong pound makes UK exports more expensive for foreign buyers and makes imports cheaper for UK consumers. This widens the trade deficit. For example, if £1 buys $1.40 instead of $1.20, UK exports become more expensive in dollar terms.

Deindustrialisation: The UK's shift from manufacturing to services over recent decades means fewer physical goods are produced domestically. Many manufactured goods that the UK once produced are now imported.

6. Reasons for a Current Account Surplus

Countries like Germany run current account surpluses for opposite reasons:

Strong export industries: Countries with globally competitive manufacturing sectors export high-value products. Germany's car industry (BMW, Mercedes, Volkswagen) and engineering sector generate massive export earnings.

Weak exchange rate: A relatively weak currency makes exports cheaper for foreign buyers and imports more expensive for domestic consumers, encouraging a surplus.

Low consumer spending on imports: Countries with high savings rates tend to import less, contributing to a surplus.

Competitive labour costs: Lower wages relative to productivity make goods cheaper to produce, giving exporters a price advantage in global markets.

7. Significance of the Balance of Payments

Why does it matter if the UK runs a current account deficit? The significance depends on the size and duration of the deficit, and how it is financed.

Short-term deficits are generally not a major concern. Countries naturally run deficits in some years and surpluses in others, depending on economic conditions.

Persistent, large deficits can be more worrying because they must be financed. If the UK spends more abroad than it earns, the difference must be covered somehow -- usually by selling UK assets to foreign investors (companies, property, government bonds) or by borrowing from abroad. Over time, this means an increasing share of UK assets and businesses becomes foreign-owned, and interest payments on borrowing flow out of the country.

The UK has run a current account deficit almost continuously since the early 1980s. In recent years, the deficit has typically been between 2% and 5% of GDP. The trade deficit in goods is large (the UK imports far more manufactured goods than it exports), but this is partially offset by a strong surplus in services, particularly financial services from the City of London.

Following the 2016 EU referendum, the fall in the value of the pound initially made UK exports cheaper and imports more expensive, which theoretically should have narrowed the trade deficit. However, the effect was limited because UK firms often import raw materials and components priced in foreign currencies, so production costs also rose. The UK's departure from the EU also introduced new trade barriers (customs checks, paperwork, regulatory divergence) that have affected both imports and exports, adding complexity to the UK's trade relationships.

8. Exam Success Strategy

For balance of payments questions, always show your working clearly in calculations -- method marks are available even if the final answer is wrong. When discussing the significance of a deficit, present both sides: explain why it could be a problem (foreign debt, loss of assets) but also why it might not be as concerning (self-correcting, reflects strong consumer demand). Use UK data where possible: reference the UK's persistent goods deficit, the services surplus, or the effects of exchange rate changes. For longer questions, build chains of reasoning: 'A strong pound makes UK exports more expensive, reducing demand from foreign buyers, which widens the trade deficit, which worsens the current account position.'
