Components of the Balance of Payments Accounts: (Cambridge International A-Level Economics)
Components of the balance of payments accounts
-
The balance of payments is a record of all financial transactions between a country and the rest of the world over a given time period - it must always balance as an accounting identity
-
The balance of payments has three main accounts:
- the current account,
- the financial account and,
- the capital account

The structure of the Balance of Payments
The current account
-
The current account was covered in detail in the AS Section, Components of the Current Account
- It records trade in goods, trade in services, primary income and secondary income
- A current account deficit means debits exceed credits - the country is a net payer of funds to the rest of the world
- A current account surplus means credits exceed debits - the country is a net receiver of funds
The financial account
- The financial account records flows of financial assets and liabilities between a country and the rest of the world - it finances imbalances on the current account
- It has four main components:
| Component | What it records | Example |
|---|---|---|
| Foreign direct investment (FDI) | - Long-term investment in productive capacity abroad or by foreigners domestically | - A US firm building a factory in Vietnam |
| Portfolio investment | - Purchase and sale of foreign financial assets - shares, bonds, securities | - A UK pension fund buying Japanese government bonds |
| Other investment | - Bank loans, trade credit, currency deposits | - A German bank lending to a Brazilian firm |
| Reserve assets | - Changes in a central bank's holdings of foreign exchange reserves and gold | - The central bank selling dollars to support the domestic currency |
- A current account deficit must be financed by a surplus on the financial account - either through attracting foreign investment, borrowing abroad or running down reserve assets
- A current account surplus must be offset by a deficit on the financial account - the country is exporting capital, building up foreign asset holdings
The capital account
-
The capital account is the smallest of the three accounts - it records non-financial, non-produced asset transfers and capital transfers between countries
- Examples include: debt forgiveness between governments, transfer of assets by migrants moving country, purchases and sales of intellectual property rights (patents, trademarks)
-
The capital account is typically very small relative to the current and financial accounts
How does the balance of payments balance?
The accounting identity
Current account + financial account + capital account = 0
- In practice, measurement errors mean a balancing item (errors and omissions) is included to ensure the accounts balance
- A current account deficit does not mean the overall balance of payments is in deficit - it means the financial and capital accounts must show a corresponding surplus to finance it
Worked Example Which components are included in the current account and financial account of the balance of payments?
Current account Financial account A Trade in goods Official reserve assets B Primary income and secondary income Trade in goods C Trade in goods and trade in services Secondary income D Trade in services and secondary income Portfolio investment and official reserve assets Final answer: Answer: D
Option D is correct - trade in services and secondary income are both current account items; portfolio investment and official reserve assets are both financial account items
Worked solution
- Option A is incorrect - official reserve assets belong to the financial account, not the current account; trade in goods alone does not represent the full current account
- Option B is the trap - primary income and secondary income are correctly identified as current account components, but trade in goods is a current account component, not a financial account component; students who confuse the two accounts may select this
- Option C is incorrect - secondary income is a current account component, not a financial account component
Exam Hint The balance of payments always balances as an accounting identity - a current account deficit must be matched by a surplus on the financial and capital accounts combined.
A common error is confusing which components belong to which account:
- trade in goods and services, primary income and secondary income belong to the current account;
- FDI, portfolio investment and reserve assets belong to the financial account;
- capital transfers belong to the capital account.
In calculations, always identify the account before assigning credits or debits - money flowing in is a credit, money flowing out is a debit.
