What the Balance of Payments is

The balance of payments records every transaction between Australia and the rest of the world over a period, usually a quarter or a year.

Worth knowing before you start: NESA's 2025 examiners reported that weaker responses on the Section III balance of payments question showed limited understanding of the complete structure of the accounts. Learn the whole architecture, not just the current account, because that is where the marks were lost.

Structure

Two main accounts, plus a balancing item.

The Current Account

This records goods, services and income, meaning flows that do not create any future obligation. Three components.

Balance on goods and services. Goods exports minus goods imports, plus services exports minus services imports. Education and tourism are Australia's largest service exports.

Net primary income. Income earned on the factors of production, so interest and dividends. Interest paid on foreign debt and profits sent home by foreign owners of Australian assets are debits. Income Australians earn on assets held overseas is a credit.

Net secondary income. Transfers where nothing comes back the other way: foreign aid, pensions paid overseas, workers' remittances. Small for Australia.

On credits and debits, the rule is simply direction. A credit is money flowing in, whether an export or income received. A debit is money flowing out. The balance is credits minus debits, so a negative figure is a deficit.

The Capital and Financial Account

This records assets and liabilities, meaning flows that do create or extinguish a future obligation.

The capital account is small: capital transfers such as migrants' assets moving in or out, plus the purchase and sale of non-produced, non-financial assets like patents and trademarks.

The financial account is the large one and the one that matters. It covers direct investment, meaning a lasting interest with control, conventionally 10% or more of a business; portfolio investment in shares and debt securities without control; financial derivatives; reserve assets, being the RBA's foreign currency and gold; and other investment, which picks up loans, deposits and trade credit.

Links between key Balance of Payments categories

This is the dot point most often examined and most often fumbled.

The accounts must sum to zero

Current account + Capital and financial account + Net errors and omissions = 0

Under a floating exchange rate the accounts offset each other automatically. Do not write the identity as "CA + KAFA = 0". That omits net errors and omissions, the statistical discrepancy that exists because the data comes from different collection sources.

Why they offset

A current account deficit means Australia is spending more on goods, services and income than it earns from them. That spending has to be financed somehow, and it is financed by selling assets to foreigners or borrowing from them, which registers as a credit on the financial account.

Put it the other way and the logic is clearer. To consume more than we produce, we must sell claims on our future income. A current account deficit is the mirror image of a financial account surplus by construction, not by coincidence.

The savings and investment gap

That is the accounting. This is the explanation, and it is the one that earns marks:

Domestic investment > domestic savings → the shortfall is financed from overseas → net capital inflow → financial account surplus → matching current account deficit

Australia's deficit is therefore structural. It is not a symptom of exporters who cannot compete. It reflects an economy with more investment opportunities than it has domestic savings to fund.

The loop that keeps the deficit going

Each year's financial account surplus adds to the stock of foreign liabilities. Servicing a larger stock produces a bigger net primary income deficit the following year, which widens the current account deficit, which needs more financing again. Naming that self-reinforcing loop is a strong analytical move and very few candidates make it.

Trends in the size and composition of Australia's Balance of Payments

The recent sequence

Australia ran current account deficits for decades, averaging roughly 4% of GDP. Then from 2019 the account moved into surplus, which was a historic reversal, driven by surging commodity prices. The surplus peaked at a record $20.5 billion in the June quarter 2021, with the goods and services surplus peaking separately at $41.3 billion in the June quarter 2022.

As commodity prices normalised the surplus eroded and the account returned to deficit. By the March quarter 2026 the current account deficit stood at $27.1 billion, and the goods and services balance had tipped into a $2.4 billion deficit, its first since the December quarter 2017.

The composition of the March 2026 deficit

Component	March quarter 2026
Balance on goods and services	−$2.4 billion
Net primary income	−$23.7 billion
Net secondary income	−$1.0 billion
Current account	−$27.1 billion

Read the second row rather than the last one. Net primary income accounts for roughly 87% of the deficit. That single proportion is the most useful piece of evidence in Topic 2, because it demonstrates that the deficit comes from the cost of servicing accumulated foreign liabilities rather than from any inability to sell exports.

It also gives you the distinction examiners were looking for in 2025. The goods and services balance is cyclical: it swings with commodity prices and the terms of trade, which is how it travelled from a $41.3 billion surplus in 2022 to a $2.4 billion deficit in 2026. The net primary income deficit is structural: it reflects the savings and investment gap and sits there regardless of where the commodity cycle happens to be.

The factors the syllabus names

International competitiveness comes from relative costs, productivity and the exchange rate, and improving it improves the goods and services balance.

The terms of trade is the ratio of export prices to import prices. When it rises, a given volume of exports buys more imports, which improves the trade balance and lifts national income. It rose 1.1% in the March quarter 2026 to an index of 96.4, still well below the record levels of the early 2020s.

International borrowing adds to net foreign debt, which stood at $1,452.6 billion at March 2026, and to the interest servicing that shows up in net primary income.

Foreign investment adds to net foreign equity, and the profits repatriated on it are also a net primary income debit.

Effects of these trends

A persistent deficit accumulates net foreign liabilities and raises the servicing burden that comes with them. It creates some vulnerability to a loss of international confidence, which could push up borrowing costs or force a sharp depreciation. Servicing obligations also take income that would otherwise be available for domestic consumption and investment.

Working against all of that, the floating exchange rate provides partial self-correction. A widening deficit tends to depreciate the currency, which improves competitiveness without anyone deciding anything.

Have the Pitchford thesis ready as the counter-argument. Where a deficit arises from private borrowing and lending between consenting parties, and funds productive investment, it is not necessarily a policy problem at all: the borrowers carry the risk and expect a return. Australia's foreign debt is predominantly private and largely either hedged or denominated in Australian dollars. That is the standard evaluative reply to alarm about the deficit, and it is worth being able to make it.

What the exam does with this

The balance of payments is among the most heavily examined areas in the course. It carried the Section III stimulus response in 2020, 2022, 2023 and 2025, and appeared in Section IV in 2018.

Five things separate a top-band answer.

Know the full structure, including the capital and financial account. The examiners said so in as many words.

Write the identity correctly, with net errors and omissions included.

Separate cyclical from structural drivers. This is the highest-value analytical move available anywhere in the topic.

Quote the composition rather than the headline. "A $27.1 billion deficit" is a fact. "A $27.1 billion deficit, of which $23.7 billion is net primary income" is an argument.

Use the savings and investment gap to explain why the deficit exists, rather than describing that it does.
