Balance of payments
This topic covers the interaction of markets, focusing on how demand and supply interact to determine market equilibrium and disequilibrium, the role of ceteris paribus, and the impact of changes in one market on related markets.
Quick Revision Summary (Key Takeaway)
The balance of payments is a record of all financial transactions between a country and the rest of the world, comprising the current account, capital account, and financial account. It must always balance overall, but imbalances in the current account (e.g., deficits or surpluses) have significant macroeconomic implications, influencing exchange rates, employment, and economic growth.
Topic Overview
The balance of payments is a crucial macroeconomic record that tracks all economic transactions between residents of a country and the rest of the world over a period. It is divided into three main accounts: the current account (trade in goods and services, primary income, and secondary income), the capital account (transfers of capital and acquisition/disposal of non-produced, non-financial assets), and the financial account (transactions in financial assets and liabilities, such as FDI, portfolio investment, and reserves). The overall balance of payments must always balance, but individual accounts can be in surplus or deficit.
For the UK, the current account has often been in deficit, meaning the value of imports and income outflows exceeds exports and income inflows. This is financed by surpluses on the financial account, as foreign investors buy UK assets. Understanding the balance of payments is essential for analysing exchange rate movements, international competitiveness, and the sustainability of external debt. It also links to other macroeconomic objectives, such as economic growth and inflation.
In OCR A-Level Economics, you need to be able to interpret data, calculate balances, and evaluate policies to correct imbalances, such as expenditure-switching policies (e.g., devaluation) and expenditure-reducing policies (e.g., deflationary fiscal policy). You should also understand the implications of deficits and surpluses for different stakeholders, including consumers, firms, and the government.
Key Concepts
Core ideas you must understand for this topic
- →Current account: records trade in goods, services, primary income (e.g., profits, interest), and secondary income (e.g., transfers).
- →Financial account: records flows of foreign direct investment, portfolio investment, and other financial flows, including changes in reserves.
- →Capital account: records transfers of capital, such as debt forgiveness and migrant transfers.
- →Balance of payments identity: current account + capital account + financial account = 0 (overall balance).
- →Causes of current account deficits: uncompetitive exports, high domestic demand for imports, exchange rate overvaluation, structural factors.

Marking Points
Key points examiners look for in your answers
- Ability to explain the interaction of demand and supply
- Ability to explain market equilibrium and disequilibrium
- Ability to construct and label diagrams showing market equilibrium and disequilibrium
- Ability to evaluate the impact of changes in demand and/or supply in one market on related markets

Examiner Tips
Expert advice for maximising your marks
- 💡Ensure diagrams are correctly labeled with price and quantity axes
- 💡Clearly distinguish between movements along curves and shifts of curves when evaluating market changes
- 💡Use the ceteris paribus assumption when explaining the impact of a single variable change
- 💡Always use the correct terminology: 'current account deficit' not 'balance of payments deficit'.
- 💡When analysing data, show your calculations clearly and use the correct units (£bn or % of GDP).
- 💡For evaluation, consider the sustainability of deficits, the nature of capital inflows (e.g., hot money vs FDI), and the impact on future generations.
Common Mistakes
Pitfalls to avoid in your exam answers
- Misconception: A current account deficit is always bad. Correction: It may indicate strong domestic demand and inward investment, and can be financed by sustainable capital inflows.
- Misconception: The balance of payments must always be in equilibrium. Correction: The overall balance always balances, but individual accounts can be imbalanced.
- Misconception: A depreciation of the exchange rate will always improve the current account. Correction: The Marshall-Lerner condition must hold (sum of price elasticities of demand for exports and imports > 1), and the J-curve effect may cause short-term worsening.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: Using the following data (in £bn), calculate the balance of trade in goods, the current account balance, and the overall balance of payments. Exports of goods: 300; Imports of goods: 350; Exports of services: 120; Imports of services: 90; Primary income (net): -20; Secondary income (net): -10; Financial account (net): +50; Capital account (net): 0.
- 1.Step 1: Calculate the balance of trade in goods: Exports of goods - Imports of goods = 300 - 350 = -50 (£bn).
- 2.Step 2: Calculate the balance of trade in services: Exports of services - Imports of services = 120 - 90 = +30 (£bn).
- 3.Step 3: Calculate the current account balance: (Balance of trade in goods + Balance of trade in services) + Primary income + Secondary income = (-50 + 30) + (-20) + (-10) = -50 (£bn).
- 4.Step 4: Calculate the overall balance of payments: Current account + Financial account + Capital account = -50 + 50 + 0 = 0 (£bn).
Question: Explain two likely macroeconomic consequences of a persistent current account deficit for the UK economy. (6 marks)
- 1.Step 1: Identify one consequence, e.g., depreciation of the exchange rate. Explain: A deficit means demand for foreign currency exceeds supply, causing the pound to depreciate.
- 2.Step 2: Identify a second consequence, e.g., potential negative impact on economic growth. Explain: If the deficit is due to high import spending, this may reduce aggregate demand and GDP, though exports may become more competitive.
- 3.Step 3: Use economic terminology such as 'exchange rate', 'aggregate demand', 'competitiveness'.
