4.18 - Interdependence Between Accounts
Interdependence between balance of payments accounts
The balance of payments records all transactions between a country and the rest of the world, with its accounts interconnected to ensure overall balance.
The balancing identity in the balance of payments
Where:
- CA = Current account balance
- FA = Financial account balance
- KA = Capital account balance (also known as the capital and financial account in some contexts)
As the capital account is usually small, the relationship simplifies to:
This shows that a current account deficit is matched by an equal financial account surplus, and vice versa. For example, if a country imports more than it exports (creating a current account deficit), it finances this through inflows in the financial account.
Autonomous and accommodating transactions
Transactions in the balance of payments are classified based on their purpose, distinguishing between those driven by economic motives and those that adjust to maintain balance.
Types of transactions in the balance of payments
- Autonomous transactions - These occur for business or economic reasons and include most items in the current account, capital account, and financial account (excluding changes in official reserves).
- Accommodating transactions - These involve changes in official reserve holdings by the central bank to offset imbalances from autonomous transactions, ensuring the overall balance of payments equals zero.
For the balance of payments to balance, accommodating transactions must equal the sum of autonomous transactions but with the opposite sign.
Balance of payments deficits and surpluses
A balance of payments deficit or surplus is determined by the net position of autonomous transactions, which influences how a country manages its international finances.
Defining deficits and surpluses
- Balance of payments deficit - Occurs when the sum of autonomous transactions is negative, requiring the central bank to use foreign exchange reserves or borrow to finance the shortfall.
- Balance of payments surplus - Occurs when the sum of autonomous transactions is positive, leading to an increase in the central bank's foreign exchange reserves or official lending to other countries.
Official reserves are treated as assets held outside the economy. Countries with limited reserves may need to borrow officially if facing a deficit, while those with ample reserves can lend abroad during surpluses.
Components of the balance of payments accounts
The balance of payments is divided into three main accounts, each capturing different types of international transactions.
The three main accounts and their components
| Account | Main components |
|---|---|
| Current account | Net exports of goods, net exports of services, net income from investments (e.g., interest and dividends), net current transfers (e.g., aid or remittances) |
| Capital account | Net capital transfers (e.g., debt forgiveness), net purchases of non-produced, non-financial assets (e.g., land or patents) |
| Financial account | Net portfolio investments (e.g., buying and selling of stocks and bonds), net foreign direct investment (FDI) (e.g., establishing businesses abroad), net deposits and loans, changes in official holdings of international reserves |
The financial account tracks inflows and outflows related to investments and reserves.
Errors and omissions in the balance of payments
Due to challenges in data collection, the balance of payments may not naturally sum to zero, requiring an adjustment entry.
Role and implications of errors and omissions
The errors and omissions entry is added to force the accounts to balance, with the same magnitude as any discrepancy but the opposite sign.
Large entries can signal issues such as:
- Illicit trade that is not officially recorded
- Underreported income held offshore
- Capital flight, where funds are moved abroad unofficially to avoid regulations or instability
