The Balance of Payments

The balance of payments is a systematic record of all economic transactions between residents of one country and the rest of the world over a given period. It is a crucial indicator of a country's external economic position and is closely linked to exchange rates, trade policy, and macroeconomic stability.

Structure of the Balance of Payments

The balance of payments has three main accounts:

1. The Current Account

Key Definition: The current account records transactions relating to trade in goods and services, primary income (investment income and compensation of employees), and secondary income (transfers).

Component	What It Includes	UK Example (2023 estimates)
Trade in goods	Exports and imports of physical products (cars, oil, machinery, food)	Deficit of approximately £150 billion
Trade in services	Exports and imports of services (financial services, insurance, consultancy, tourism, education)	Surplus of approximately £80 billion
Primary income	Net investment income (dividends, interest, profits from overseas assets), net compensation of employees	Small surplus or deficit (varies year to year)
Secondary income	Net current transfers (e.g., UK contributions to EU budget, overseas aid, remittances)	Deficit (UK is a net contributor)
Current account balance	Sum of all four components	Deficit of approximately 3–4% of GDP

Exam Tip: The UK has run a persistent current account deficit since the early 1980s, primarily driven by the deficit on trade in goods. However, the UK runs a significant surplus on trade in services (especially financial services from the City of London). Always mention both when discussing the UK current account.

2. The Capital Account

The capital account records:

• Capital transfers (e.g., debt forgiveness, migrants' transfers of assets)
• Transactions in non-produced, non-financial assets (e.g., purchases of patents, copyrights, land by embassies)

The capital account is typically very small relative to the current and financial accounts.

3. The Financial Account

Key Definition: The financial account records transactions involving the purchase and sale of financial assets (shares, bonds, property, direct investment) between residents and non-residents.

Category	Description	Example
Foreign Direct Investment (FDI)	Investment in productive capacity — buying or establishing businesses in another country (10%+ ownership stake)	Nissan's factory in Sunderland; Tata's ownership of Jaguar Land Rover
Portfolio investment	Purchase of financial assets (shares, bonds) without significant management control	Foreign investors buying UK government gilts
Other investment	Bank loans, trade credit, currency deposits	A UK bank lending to a foreign company
Reserve assets	Changes in the central bank's holdings of foreign currency and gold	Bank of England intervening in foreign exchange markets (rare)

The Balance of Payments Must Balance

Current account + Capital account + Financial account + Net errors and omissions = 0

This is an accounting identity. If the UK runs a current account deficit (importing more than it exports), it must be financed by a surplus on the financial account — meaning net capital inflows. In other words, foreigners must be investing more in the UK than the UK is investing abroad.

Exam Tip: Students often state that the balance of payments is "in deficit" or "in surplus." The overall balance of payments always balances by definition. What can be in deficit or surplus is a particular account — most commonly the current account.

Causes of a Current Account Deficit

The UK's persistent current account deficit has several underlying causes:

Structural Factors

1. Deindustrialisation — the long-term decline of UK manufacturing since the 1970s has reduced the country's capacity to produce goods for export, while demand for imported manufactured goods has remained strong.
2. Comparative advantage in services — the UK has a strong comparative advantage in financial services, education, and creative industries, but these have not fully offset the goods deficit.
3. Exchange rate — a relatively strong pound makes UK exports more expensive and imports cheaper, widening the trade deficit.
4. Income elasticity of demand — if UK consumers have a high income elasticity of demand for imports (i.e., as incomes rise, import spending rises more than proportionally), a growing economy will tend to widen the current account deficit.

Cyclical Factors

5. Domestic economic growth — rapid growth increases demand for imports (consumer goods, raw materials, capital equipment), worsening the trade balance.
6. Relative inflation rates — if UK inflation exceeds that of trading partners, UK goods become less competitive.
7. Global economic conditions — a recession in major export markets (e.g., the Eurozone) reduces demand for UK exports.

Financial Factors

8. Primary income flows — the balance of investment income depends on the relative returns on UK assets held abroad versus foreign-owned assets in the UK.
9. Secondary income — the UK is typically a net contributor to international transfers.

Causes of a Current Account Surplus

Some countries (e.g., Germany, China, Japan, Norway) run persistent surpluses. Possible causes include:
