Every cross-border transaction a country makes, every export, import, dividend, loan and investment, is recorded in the balance of payments (BoP), a double-entry ledger. Because it is double-entry, the BoP always balances by construction: every rupee that leaves must be accounted for by a rupee that comes in somewhere. Learn its two great halves and the identity that binds them. It is the accounting spine of the entire external sector, and M7.07's dashboard is built on it.
The current account (CA): the flow of goods, services, and income. The current account records the country's trade and its income from the rest of the world. Three components:
- The trade balance. Goods exports minus goods imports (the "merchandise" balance) plus the services balance. India runs a large goods deficit (it imports oil, gold, electronics, machinery) but a large services surplus (IT/software exports and business services, the Infosys/TCS story of M5.06), which offsets a big chunk of the goods gap. The US runs a large goods deficit and a services surplus too, but nets to a persistent overall deficit.
- Primary income. Net investment income: interest, dividends, and profits earned on foreign assets minus those paid to foreigners on their assets here. A country that has borrowed heavily from abroad pays out more than it earns (a drag); a creditor nation like Japan earns a large net income surplus.
- Secondary income (transfers). Chiefly remittances. This is huge for India: workers abroad send home the world's largest remittance inflow (~$100bn+/yr), a stable, non-debt-creating credit that materially shrinks India's current-account deficit.
Net them and you get the current-account balance: a surplus (China, Germany, Japan, oil exporters) means the country sells more to the world than it buys and is a net lender to the world; a deficit (US, India, most fast-growing importers of capital) means it buys more than it sells and must be a net borrower from the world. India typically runs a modest CA deficit of ~1–2% of GDP, importing capital to fund investment beyond its own savings.

What is the capital and financial account?
The capital and financial account (KA/FA): the flow of assets and claims. This records cross-border purchases of assets: who is buying whose factories, bonds, shares, and bank deposits. Its subcomponents are where the analyst's judgment lives:
- Foreign direct investment (FDI). A foreigner building or buying a controlling, operating stake (a factory, a subsidiary, a >10% equity position). FDI is sticky: you cannot pull a factory out of a country overnight, so FDI is patient, long-horizon capital that stays through turbulence.
- Portfolio investment (FPI/FII). Foreigners buying tradable securities: listed equities and bonds, without control. This is "hot money": it can be sold and repatriated in days at the click of a mouse, and it is precisely the capital that floods in when conditions are benign and stampedes out when they turn (see capital flows). India's stock and bond markets are heavily influenced by FPI flows day to day.
- Other investment. Cross-border bank loans, trade credit, external commercial borrowings (dollar debt taken by Indian firms), and currency/deposits.
- Reserve assets. The change in the central bank's FX reserves, which is the balancing item: if private flows don't cover the current account, the central bank's reserves move to close the gap.
Why does the balance of payments sum to zero?
Why the two halves must sum to (near) zero. Here is the identity that unlocks everything:
Current account + Capital/Financial account + Errors & omissions = 0
Equivalently, Current account balance = − Capital/Financial account balance (before the small errors term). This is not a coincidence or a policy goal. It is an accounting identity, true by construction. The intuition: if India buys $50bn more goods from the world than it sells (a $50bn current-account deficit), it must pay for that excess with $50bn, and the only ways to pay are to sell $50bn of assets to foreigners (FDI + FPI + borrowing inflows, a capital-account surplus) or to run down $50bn of reserves. A current-account deficit is, definitionally, financed by a capital-account surplus (net capital inflow) or by drawing down reserves. Turn it around and it is even more illuminating: a country running a CA deficit is a country importing capital. It is not inherently "living beyond its means" in a bad sense; the US and India both run CA deficits precisely because the world wants to invest in them. The deficit is the flip side of being an attractive destination for capital.
How is the balance of payments split in the sixth edition?
The three accounts under the sixth edition, and the two transactions the older split misfiles. The presentation above, a current account facing one merged capital-and-financial account, is the fifth-edition framing. It is still the vocabulary of most commentary and it is how the phrase "capital account convertibility" entered Indian policy debate. The current manual, the IMF's sixth edition of the Balance of Payments and International Investment Position Manual, splits that second half in two, and the split moves two specific transactions.
- The current account is unchanged: goods, services, primary income, secondary income.
- The capital account is small and specific. It holds capital transfers, of which debt forgiveness is the standard case, and the acquisition or disposal of non-produced, non-financial assets, of which an outright sale of a patent, a trademark or a marketing right is the standard case.
- The financial account holds everything that is a claim: direct investment, portfolio investment, financial derivatives, other investment, and reserve assets.
The identity then carries three terms and one sign convention that catches people:
Financial account (net lending, +) = Current account + Capital account + Net errors and omissions
The financial account is measured as net lending to the world, meaning net acquisition of foreign assets minus net incurrence of liabilities to foreigners. A country running a current-account deficit is a net borrower, so its financial-account balance is negative. Take a stylised year with a current-account deficit of $47bn, a capital-account surplus of $1bn and errors and omissions of $2bn: the financial account is −47 + 1 + 2 = −$44bn of net lending, which is $44bn of net borrowing from the rest of the world.
Two consequences for your own classification work. Debt forgiveness and an outright patent sale belong in the capital account, and calling the whole second half "the capital account" misfiles them every time. And reserve assets sit inside the financial account, as an asset the central bank acquires, which is why a reserve build raises net lending rather than sitting outside the identity. India's balance-of-payments statements follow the sixth edition; older tables and a great deal of commentary do not, so verify against the RBI's current balance-of-payments release before you quote a block heading. Practice items P4 and P19 drill the split.
Why does the quality of financing matter?
The danger is never the deficit level alone. It is the quality of the financing.
FDI-financed versus hot-money-financed: the same deficit, opposite safety. Two countries each run a 3%-of-GDP current-account deficit. Country A finances it with FDI and long-term inflows; Country B finances it with short-term portfolio "hot money." A is safe, because its financing cannot flee. B is a sudden-stop candidate: the day global risk appetite turns (a Fed hike, a VIX spike), the hot money reverses, and B faces a currency collapse and a funding crisis even though its deficit was identical to A's (capital flows is this mechanism in full). This is the single most important lens on the external accounts. Do not ask only "how big is the deficit?" Ask "what is financing it, and can that financing run?" India's post-2013 buffer-building (see capital flows) is substantially a shift toward safer financing (more FDI, larger reserves, remittance stability) and away from hot-money reliance.
What are the twin deficits?
The twin deficits: the bridge from the budget to the border. One more identity, and it connects all this to fiscal policy (M7.04). From the national accounts, the current-account balance equals national saving minus national investment, which can be split into a private piece and a government piece:
Current account = (Private saving − Investment) + (Tax revenue − Government spending)
The second bracket is the government's budget balance. Hold private saving-investment roughly constant, and the identity says that a wider fiscal deficit (G > T) tends to widen the current-account deficit, hence "twin deficits." The US is the archetype: chronic budget deficits and chronic current-account deficits, twinned. The mechanism in words: when the government dis-saves (borrows), and the private sector doesn't fully offset it by saving more, the nation as a whole saves too little to fund its investment, so it imports the shortfall of savings from abroad, which is a current-account deficit financed by capital inflow. Present the caveat fairly. It is an identity-driven tendency, not an iron law, and the link can be muted if private saving rises to offset government borrowing (partial "Ricardian equivalence") or if investment adjusts. But as a first-order reasoning tool, "a country that suddenly runs much larger budget deficits will, all else equal, tend to run larger external deficits and face more currency pressure," the twin-deficits lens is one an analyst uses constantly.
