Balance of Payments: Current Account and Capital Account Explained

The balance of payments is one period's record of everything that crossed a country's border, sorted into what the country earned and spent and what it lent, borrowed or invested. The two sides balance every time, not because the world is tidy, but because whatever was not paid for out of earnings had to be paid for with a claim handed over instead.

Underneath that sits a single accounting habit. Every cross border transaction has two ends, and the balance of payments insists on writing down both. A shipment of machinery arriving in a country is one end; whatever left the country to pay for it, whether that was export earnings already banked or a promise to repay later, is the other. Once that rule is accepted, the two accounts stop being two lists and become two halves of the same sentence.

Why does the current account here differ from the one under the trade balance?

There are two current account figures for the same country. The earlier treatment of the trade balance worked the Republic of Sankhya, an invented country used throughout this material, and reported a current account of plus Rs 150 crore. The account assembled here works the same invented country and reports minus Rs 14,000 crore. Neither figure is a mistake, and the reason is worth the two minutes it takes.

The earlier treatment said on its face what it was doing. The trade balance measured one product pair, a single good going out against a single good coming in, and set cross border income and transfers to nil so the contrast it wanted to draw would stay clean. Goods came to minus Rs 250 crore, services to plus Rs 400 crore, and the two summed to plus Rs 150 crore. Nothing else was in the frame. The two treatments describe the same country at two different widths of measurement. The figures differ by construction rather than by contradiction. This guide opens the frame to the whole economy and switches income and transfers back on, and both of those lines are large.

The lesson is worth a habit rather than a one time explanation. When two credible sources give two different figures for the same quantity in the same country, the first question is never which one is wrong, but what each one was measuring. A household that says it spent Rs 40,000/- last month and Rs 12,000/- last month is not lying twice; one figure is everything and the other is groceries. Width first, then arithmetic.

What does the current account record?

The current account records what a country earned and what it spent across its border in the period. Four kinds of thing sit inside it. Goods, meaning physical items shipped in and out. Services, meaning work done across a border without anything physical moving, such as software written for a buyer abroad or a foreign visitor paying for a hotel room. Income earned on what a country holds abroad, and paid out on what foreigners hold inside it. The accounts call that line primary income. And remittancesMoney sent home by people working abroad, with nothing sent back the other way in exchange. Treated in its own right and covered separately., which are transfers sent with nothing coming back in exchange.

Every line in the current account is a fact about a period that has closed: something was shipped, worked, earned or sent, and that event is over. That single property is what separates this account from the other one, and it is the thing to hold on to before any of the arithmetic. Think of a household ledger for one month. Salary in, rent out, a gift sent to a cousin in another city. When the month ends, those entries are settled. Nobody owes anybody anything on account of them.

Worked on the Republic of Sankhya, the four lines run as follows. Goods exports of Rs 2,75,000 crore against goods imports of Rs 3,85,000 crore leave a goods balance of minus Rs 1,10,000 crore. Services come in at plus Rs 64,000 crore. Sankhya pays out more on what foreigners hold inside it than it collects on what it holds abroad, so primary income runs at minus Rs 26,000 crore. Remittances add plus Rs 58,000 crore. The four sum to minus Rs 14,000 crore, or 0.80 per cent of Sankhya's output measureThe total value of what a country produces in a period. Built up separately; used here only as the denominator that turns a rupee figure into a share. of Rs 17,47,200 crore.

What does the capital account record?

The capital account records claims rather than earnings. Money put into a business abroad so as to run part of it is a claim. Money put into tradable stakes is a claim. Money lent across a border, and money borrowed across it, are claims in opposite directions. Nothing in this account is a payment for something used up in the period. Every entry creates or extinguishes a relationship that outlives the period the account covers.

A current account entry is a fact about a period that has closed. A capital account entry is a promise about a future that has not happened yet. Mixing the two is the commonest confusion in this subject. The confusion is easy to fall into because both are measured in rupees and both appear in the same table. The household test applies again. A salary landing is a current account style entry: it happened. A home loan taken to buy a flat is a capital account style entry: the money arrived, and so did an obligation that will still be there in fifteen years.

On the Sankhya account the capital side carries three lines. Direct investmentMoney put into a business abroad by someone who intends to run or control part of it, rather than to hold a stake they can sell on a market. Compared with the other kind separately. comes in at plus Rs 22,000 crore. Portfolio investmentMoney put into stakes that trade on a market and can be sold on quickly, held for the return rather than for control of the business. runs at minus Rs 6,000 crore, meaning more of that kind of money left Sankhya than arrived. Net external borrowingBorrowing from lenders outside the country, netted against repayments made to them in the same period. adds plus Rs 3,000 crore. The three sum to plus Rs 19,000 crore. The total hides the important part: the capital account is in surplus while one whole kind of foreign money is walking out of the door. A single net figure can be positive while an important component of it is negative, and that is true of every net figure anywhere.

Why does the balance of payments always balance?

Because it was built to. The identity is where the wrong conclusion is most often drawn, so the shape of the argument is worth naming before the numbers arrive. The balancing is an identity: it holds by construction, it cannot fail, and therefore it can never confirm that any figure in the account is right.

Here is the construction. Sankhya's current account is minus Rs 14,000 crore and its capital account is plus Rs 19,000 crore. Adding them gives plus Rs 5,000 crore, exactly the change in Sankhya's foreign exchange reservesThe stock of foreign currency and similar assets a central bank holds. What it is for, and how its size is read, are covered separately.. The match is not a coincidence and not a test that was passed. A country pays for whatever its earnings did not cover by handing over a claim. Whatever is left after those two are set against each other is the movement in reserves, and any part of the total that the recording missed is written into a residual line called errors and omissions. There is no fourth place for a number to go.

One test separates a real check from a restatement: could this ever come out differently? If the answer is no, the relationship describes how the account was assembled, not whether the entries are true. A cash book that computes closing balance as opening balance plus receipts less payments will always balance, no matter how wrong the receipts are. The identity shows one thing only, and it is the central sentence: a deficit is not a shortfall of money but a claim handed over instead.

What does it mean to say a deficit was funded?

Sankhya spent Rs 14,000 crore more across its border than it earned across it, and that gap is the current account deficit. Against it, Rs 19,000 crore of claims came in: foreigners put money into Sankhya businesses, bought stakes, and lent to Sankhya borrowers. Rs 14,000 crore of those claims paid for the gap. The remaining Rs 5,000 crore had nowhere else to go and added to reserves.

Nothing ran out and nothing was rescued: Sankhya exchanged a claim on its own future output for goods and services it took delivery of now. That is a trade, not an emergency. A young household does exactly this when it borrows to buy a flat. In the year of the purchase it consumed far more housing than it earned, and it funded the difference by handing the lender a claim on fifteen years of future salary. Whether that was a good decision depends entirely on what was bought and on what the future salary looks like. The ledger for the year settles neither question. The ledger records only that the exchange happened.

The same limit applies here, and it is a real limit rather than modesty. Whether Sankhya's deficit was worth running depends on what the imports were for. Machinery that raises what the country can produce later is a different matter from consumption that leaves nothing behind, and the balance of payments does not distinguish between them. The account records the rupee amount and the claim, and stops.

Why is errors and omissions a real line rather than an embarrassment?

Every cross border transaction has two ends, and the two ends are recorded by different people, at different moments, through different channelsThe route by which a figure reaches the office that compiles the statistics: a bank return, a customs declaration, a survey response, a filing. Different routes carry different lags and coverage.. A customs declaration is not the same document as a bank return, and neither is a survey of businesses. The two ends therefore never quite meet, and the amount by which they fail to meet has to be written somewhere or the account would not close.

Errors and omissions is a measurement residual rather than a mistake, and a large one is information about how well the counting is going rather than an admission of incompetence. When it is small, the two sides of the recording are broadly agreeing with each other. When it swells, something is being recorded on one side and not the other, and that on its own is worth asking about. Compilers publish it openly for exactly that reason.

The trap sits in the other direction. Because the residual is worked out from the other lines rather than counted, it will absorb any error anywhere on the account without complaint. If one import figure is overstated, the residual quietly grows by the same amount, and the account still closes. The panel below is built to show that property, and it is the reason the closing is not a check.

What does the balance of payments leave out?

The balance of payments does not say whether a deficit can go on. SustainabilityWhether a pattern can continue without something being forced to change. A judgement about the future, not a figure any single period's record contains. is a judgement about years ahead, and the balance of payments is a record of one period that has already closed. A country can run the same deficit for a decade without difficulty and another can find the same number unmanageable, and nothing inside the account separates the two cases.

The account does not say who the claims are owed to, on what terms, or what happens if the holders want out at the same time. The capital account gives a net figure per kind of money. A net figure does not give the maturity of the borrowing, the identity of the lenders, or how quickly any of it can turn around. The balance of payments is a record of a period, not a forecast, and treating it as a forecast is how a perfectly accurate table gets read as a warning or an all clear it never issued. What the reserves it settles into can and cannot cover is covered separately.

What does an analyst look at first?

Not the headline. Two deficits of identical size can be entirely different events, so an analyst reading an external account for the first time goes straight to which line moved. Suppose Sankhya's current account widens from minus Rs 14,000 crore to minus Rs 30,000 crore. If goods imports did the widening, the country bought more from abroad, and the next question is what it bought. If primary income did the widening, the country is paying out more on claims foreigners already hold. The bill is for capital that arrived in earlier periods, and it is much harder to switch off.

The same discipline applies on the capital side. A capital account that holds steady in total while its composition shifts from direct investment towards short dated borrowing has changed character without changing its number. The total is the one figure on the account that cannot say what happened, so an analyst reads the composition before the total. A lender assessing a country, an investor sizing currency exposure and an economist writing a review all run the same first step, and all of them treat the closing arithmetic as bookkeeping rather than as evidence.

What does the whole Sankhya external account look like assembled?

Here is the full account in the order the teaching needs it. Every figure belongs to the Republic of Sankhya and is stated in Rs crore. Negative amounts are written as words in the tables so a stray minus sign cannot be misread.

The arithmetic is the least interesting part of the last table, so read it in words instead. Sankhya took delivery of Rs 14,000 crore more than it earned abroad. Foreigners handed it Rs 19,000 crore of money in exchange for claims on Sankhya. Rs 14,000 crore of that paid for the gap and Rs 5,000 crore was left over, so reserves rose. No money was found and none ran short. A claim was written instead, and the account recorded it.

Move the slider far in either direction and the account still closes. The closing is the whole lesson of the panel, and it is easier to feel than to be told. Change any single line by a given amount and the residual takes up exactly that amount, in the opposite direction to the effect on the account the line sits in. The closing arithmetic would have worked just as neatly on a figure that was nonsense. The picture below freezes two of those settings side by side.
