IB DP Economics — Unit 4: The Global Economy | SL | 4.6 Balance of Payments
📋 What You Will Learn
- Define the balance of payments and explain its purpose as a record of international transactions
- Identify and distinguish between the current account, capital account, and financial account
- Explain the components of the current account: trade in goods, trade in services, primary income, and secondary income
- Analyse the causes and consequences of current account deficits and surpluses
- Apply the concept of balance of payments equilibrium and explain why the overall account always balances
- Evaluate policy responses to persistent current account imbalances
🔍 Guiding Question When a country persistently spends more on imports than it earns from exports, what does this reveal about its economy — and does it matter?
🌍 Why This Matters In 2023, the United States recorded a current account deficit of approximately $905 billion — meaning Americans collectively spent nearly a trillion dollars more on foreign goods, services, and income transfers than the rest of the world spent on American ones. Meanwhile, Germany ran a current account surplus of over $250 billion. These imbalances are not accounting curiosities: they shape exchange rates, employment, debt levels, and the entire structure of the global economy.
What Is the Balance of Payments?
Every time a country trades with the rest of the world — buying imports, selling exports, receiving investment income, or attracting foreign capital — those transactions are recorded. The balance of payments is the systematic record of all these flows.
📖 Definition — Balance of Payments (BOP) The balance of payments is a record of all economic transactions between residents of one country and the rest of the world over a given period of time, typically one year. It is divided into the current account, the capital account, and the financial account.
💡 The Fundamental Principle The balance of payments always balances in total. A deficit on one account must be offset by a surplus on another. If a country imports more than it exports (current account deficit), it must be financing that gap through borrowing, selling assets, or attracting foreign investment (financial account surplus). Money flowing out must equal money flowing in — the accounts are two sides of the same coin.
The Current Account
The current account is the most closely watched component of the balance of payments. It records flows of income between a country and the rest of the world — the ongoing, recurring transactions that reflect the productive capacity and spending patterns of the economy.
📖 Definition — Current Account The current account records all transactions in goods, services, primary income, and secondary income between residents of a country and the rest of the world over a given period. A current account surplus means inflows exceed outflows; a deficit means outflows exceed inflows.
1. Trade in Goods (Visible Trade)
- Records exports and imports of physical goods — cars, machinery, food, oil, clothing
- Exports of goods → credit (money flowing in)
- Imports of goods → debit (money flowing out)
- The difference = balance of trade in goods (also called the "visible balance" or "merchandise trade balance")
- A deficit in goods trade is common for advanced service economies (e.g. UK, USA) that import manufactured goods from lower-cost producers
2. Trade in Services (Invisible Trade)
- Records exports and imports of intangible services — tourism, financial services, education, transport, insurance, consulting
