ECON3520 Chap.1 Balance of Payments and International Accounts
Balance of Payments and International Accounts
International accounts turn every cross border transaction into a signed pair. The current account records trade in goods and services, income and unilateral transfers. The financial account records changes in asset ownership.
This chapter shows why the two balances offset, how to classify services, transfers and asset purchases, and how the current account moves the net international investment position separately from valuation changes.
The central discipline is to classify the economic object before following its payment.
A service export, an income receipt and a resident purchase of a foreign asset belong in different rows even if each arrives through the same bank. Double entry then supplies an offsetting record, while the NIIP bridge explains how transaction flows and valuation changes carry an opening external position to its closing value.
The worked material keeps the country perspective explicit, separates stocks from flows and uses a reconciliation check after every calculation.

Worked example · free
Reconcile a current account flow with closing NIIP
- 1Start from the stock flow identity: closing NIIP equals opening NIIP plus current account plus valuation change.
- 1Substitute minus 240 plus 18 minus 12, which gives closing NIIP of minus 234.
- 1Interpret the movement: transactions improve the position by 18, valuation worsens it by 12, and the net improvement is 6.
Key terms
- Balance of Payments
- The Balance of Payments is the signed record of a country's transactions with the rest of the world.
- Service Balance
- The Service Balance is exports of services minus imports of services.
- Net Investment Income
- Net Investment Income is returns received on foreign assets minus returns paid on domestic liabilities held abroad.
- Unilateral Transfer
- A Unilateral Transfer is a one way cross border flow without a good, service or asset received in exchange.
- Double Entry
- Double Entry records two offsetting sides of each international transaction.
Balance of Payments and International Accounts FAQ
Why must the current and financial accounts offset?
A cross border exchange has a real or income side and a financing side. An import, for example, is a negative current account entry, while the foreign seller's acquisition of a domestic claim is a positive financial account entry. Recording both sides makes the balances sum to zero.
Can a transaction create two financial account entries?
Yes. A resident can acquire a foreign asset while the foreign seller acquires domestic currency. One entry is negative and the other positive in the financial account, with no current account flow. The rule is two offsetting entries, not necessarily one entry in each account.
How can NIIP change without a current account transaction?
Foreign asset prices, domestic liability prices or exchange rates can change the value of an existing portfolio. Those valuation effects move NIIP even when no asset is bought or sold. Closing NIIP therefore includes both the current account flow and a separate valuation change.
Exam move
Classify before calculating. For every transaction, name the country perspective, identify the good, service, income, transfer or asset, assign its sign, then find the offsetting entry. Build current account totals from their components rather than memorising a single sign. For NIIP questions, draw an opening stock, a current account arrow, a valuation arrow and a closing stock.
Redo the practice cards until CA plus FA equals zero automatically and you can explain why a negative NIIP is a stock position rather than a current period deficit. Use three separate drill sets. In the first, classify one transaction at a time and say aloud why it is a good, service, income, transfer or asset flow. In the second, pair each signed entry with its offset without computing an aggregate.
In the third, combine several entries into the current and financial accounts and reconcile the totals. Keep an error log that distinguishes a category mistake from a sign mistake. For stock-flow questions, write the NIIP equation before inserting numbers, and circle valuation effects so they cannot be mistaken for transactions.
A final check should answer four questions: whose perspective is used, what crossed the border, which account records it, and what entry completes double entry. If the arithmetic balances for the wrong classification, redo the economic description rather than accepting the zero mechanically.
