1. An open economy and the balance of payments
An open economy trades with the rest of the world: it exports and imports goods, services and capital. All these transactions are recorded in the balance of payments (BoP) account — a systematic record of a country's economic transactions with the rest of the world in a year.
The BoP has two main accounts. The current account records trade in goods (visible items) and services, income and transfers (invisible items). The capital account records capital flows: foreign investment, loans and banking capital. In accounting terms the BoP always balances, but a country can still run a current account deficit, financed by a capital account surplus.
2. Balance of trade vs balance of payments
Balance of trade (BoT) covers only goods: exports of goods minus imports of goods. It can be favourable (surplus) or unfavourable (deficit). Balance of payments is wider: it includes goods, services, income, transfers and capital flows.
A country can have a trade deficit but a BoP surplus on current account if its service exports (like software) and remittances from workers abroad outweigh the goods deficit — a common situation for India. That is why BoT and BoP must never be confused.
3. Foreign exchange rate and its systems
The foreign exchange rate is the price of one currency in terms of another — for example, Rs 83 per US dollar. If more rupees are needed to buy a dollar, the rupee has depreciated (its value fell); if fewer rupees are needed, it has appreciated.
Under a fixed exchange rate system, the government or central bank fixes the rate. Under a flexible (floating) rate system, the rate is set by demand and supply of foreign exchange in the market. Under managed floating, the market sets the rate but the central bank intervenes — buying or selling foreign currency — to prevent sharp swings. India follows managed floating.
4. How the exchange rate is determined, and why it matters
In a floating system, demand for foreign exchange comes from importers, tourists going abroad and investors buying foreign assets; supply comes from exporters, foreign tourists and foreign investors. If demand for dollars rises, the dollar becomes dearer and the rupee depreciates.
Depreciation makes exports cheaper for foreigners (good for exporters) but imports dearer (fuel and machinery cost more, feeding inflation). Appreciation does the reverse: imports become cheaper, but exporters lose competitiveness. Exchange rate movements therefore affect prices, jobs and the trade balance.

Current account versus capital account, component by component. The current account records flows of goods and services and income: exports and imports of goods (the balance of trade), exports and imports of services (invisibles — software, tourism, transport), income (interest, dividends, wages earned abroad), and transfers (remittances, gifts, foreign aid). The capital account records changes in ownership of assets: borrowings from abroad, foreign investment (FDI and portfolio investment), banking capital and NRI deposits. A current-account deficit means the country spends more abroad than it earns; it must be financed by a capital-account surplus (or by running down official reserves).
Why the balance of payments always balances — and what a "deficit" then means. Every international transaction is recorded twice (once as a credit, once as a debit), so total credits always equal total debits: the BoP balances in the accounting sense by construction. When newspapers report a "BoP deficit", they mean a deficit on autonomous transactions (trade and investment done for their own sake) — which is then covered by accommodating transactions, mainly the central bank selling foreign exchange reserves. A persistent autonomous deficit that drains reserves is the real problem behind the headline.
Fixed, flexible and managed floating — and India's system. Under a fixed system the central bank announces a rate and buys or sells foreign exchange to hold it; a deliberate fall is a devaluation, a rise a revaluation. Under a clean float the rate moves purely with market demand and supply; a fall is depreciation, a rise appreciation. India follows managed floating (a dirty float): the market largely decides the rate, but the RBI intervenes — selling dollars to stop a sharp rupee fall, buying dollars to stop a sharp rise — to prevent excessive volatility without fixing the rate.
Depreciation: who gains, who loses, and the inflation channel. When the rupee depreciates (say Rs 82 to Rs 88 per dollar), Indian exports become cheaper abroad, so exporters gain and export volumes tend to rise; imports become dearer, so importers and consumers of imported goods (notably oil) lose, and the higher import bill can feed domestic inflation. That is why a depreciating rupee is welcomed by exporters but watched anxiously by the central bank — and why the RBI sometimes intervenes even under a floating system.

At a glance — current account vs capital account
| Account | Records | Examples |
|---|---|---|
| Current account | Goods, services, income, transfers | Export of rice; software services; remittances from abroad |
| Capital account | Capital flows | Foreign investment in India; loans from abroad |
| Balance of trade | Goods only | Exports of goods minus imports of goods |
| Balance of payments | All transactions | Current + capital accounts together |
Key Terms / Important Terms
- Balance of payments (BoP) — Systematic record of a country's economic transactions with the rest of the world in a year.
- Current account — BoP account recording trade in goods and services, income and transfers.
- Capital account — BoP account recording capital flows such as investment and loans.
- Balance of trade — Exports of goods minus imports of goods.
- Foreign exchange rate — Price of one currency in terms of another currency.
- Depreciation — Fall in the value of a currency under a floating rate, e.g. more rupees per dollar.
- Appreciation — Rise in the value of a currency under a floating rate, e.g. fewer rupees per dollar.
- Managed floating — A system where the market sets the exchange rate but the central bank intervenes to limit sharp swings.
Remember
- BoP is wider than BoT: BoT = goods only; BoP = goods + services + income + transfers + capital.
- Depreciation: more rupees per dollar. Appreciation: fewer rupees per dollar.
- India follows managed floating.
- A current account deficit can be financed by a capital account surplus.
Exam Tip / Common Mistake
Common mistake: saying the rupee 'depreciates' when fewer rupees buy a dollar. Fewer rupees per dollar means the rupee is STRONGER — that is appreciation. Always ask: does one dollar cost more rupees (depreciation) or fewer rupees (appreciation)?
Practice set — try it yourself
- Exports of goods Rs 400 crore, imports of goods Rs 550 crore. Find balance of trade and say whether it is surplus or deficit. Hint: Hint: 400 − 550. Negative means deficit.
- The exchange rate moves from Rs 80 to Rs 85 per dollar. Has the rupee depreciated or appreciated? Why? Hint: Hint: A dollar now costs more rupees — the rupee is weaker.
- Distinguish between balance of trade and balance of payments. Hint: Hint: BoT = goods only; BoP = everything, including services, income, transfers and capital.
- Why might a country with a trade deficit still be comfortable? Give one reason. Hint: Hint: Service exports and remittances can outweigh the goods deficit.
- Depreciation of the rupee: who gains, exporters or importers? Why? Hint: Hint: Exporters gain — their goods become cheaper abroad; importers pay more.
Questions with Answers
- What is the balance of payments? Name its two main accounts and what each records. Answer: The systematic record of a country's transactions with the rest of the world in a year. Current account: goods, services, income and transfers. Capital account: capital flows like investment and loans.
- Distinguish between balance of trade and balance of payments. Answer: Balance of trade covers goods only (exports minus imports of goods). Balance of payments covers all transactions — goods, services, income, transfers and capital flows.
- What is a foreign exchange rate? Explain depreciation and appreciation with numbers. Answer: The price of one currency in terms of another. If the rate moves from Rs 80 to Rs 85 per dollar, the rupee has depreciated (a dollar costs more rupees). If it moves to Rs 75, the rupee has appreciated.
- Distinguish between fixed and flexible exchange rate systems. Which does India follow? Answer: Fixed: the government/central bank fixes the rate. Flexible: demand and supply in the market fix it. India follows managed floating — market-determined with central bank intervention against sharp swings.
- How does a rise in demand for foreign exchange affect the exchange rate? Answer: Higher demand for dollars (more imports, more foreign investment abroad) makes dollars dearer: the rupee depreciates until demand and supply balance again.
Extension Questions with Answers
Board-style extension practice, written by Educational Galaxy. These are practice questions, not real past-year questions.
- Classify each as current or capital account, with a reason: (a) an Indian company borrows from a foreign bank, (b) an Indian tourist spends abroad, (c) an NRI sends money home to family, (d) a foreign firm buys shares in an Indian company. Answer: (a) Capital — borrowing changes asset ownership/liabilities. (b) Current — payment for a service (tourism). (c) Current — a transfer with no return. (d) Capital — foreign investment in assets.
- Distinguish devaluation from depreciation, and state which system each belongs to. Answer: Devaluation is a deliberate fall in the exchange rate fixed by the central bank under a fixed exchange rate system. Depreciation is a market-driven fall under a flexible (or managed floating) system.
- Autonomous transactions show a deficit of Rs 50,000 crore. How is it covered, and what happens to official reserves? Answer: It is covered by accommodating transactions — mainly the central bank selling foreign exchange reserves (or the country borrowing abroad). Official reserves fall by Rs 50,000 crore.
- The rupee appreciates from Rs 85 to Rs 80 per dollar. Explain one gain and one loss for the Indian economy. Answer: Gain: imports become cheaper — oil and machinery cost less, easing inflation. Loss: exports become dearer abroad, so exporters sell less and export earnings may fall.
- Why does the RBI intervene under managed floating? Give one example each of intervention against a sharp fall and a sharp rise of the rupee. Answer: To prevent excessive volatility that disrupts trade and investment, without fixing the rate. Against a sharp fall: the RBI sells dollars from reserves, increasing dollar supply. Against a sharp rise: the RBI buys dollars, increasing rupee supply and holding the rupee down.
Board Exam Questions — board-pattern practice
These questions are written by Educational Galaxy in board-exam style for practice. They are not claimed to be real past-year questions.
- Exports of goods Rs 300 crore, imports of goods Rs 420 crore, net services +Rs 150 crore, net transfers +Rs 40 crore. Find balance of trade and current account balance. Answer: Balance of trade = 300 − 420 = −Rs 120 crore (deficit). Current account = −120 + 150 + 40 = +Rs 70 crore (surplus). The goods deficit is outweighed by services and transfers.
- The rupee depreciates from Rs 82 to Rs 88 per dollar. Explain two effects on the Indian economy. Answer: Exports become cheaper for foreign buyers, helping exporters and jobs in export industries. Imports become dearer, raising costs of fuel and machinery and pushing up domestic prices (imported inflation).
- Distinguish between current account and capital account with two examples of each. Answer: Current account: export of textiles (goods), remittances from workers abroad (transfers). Capital account: a foreign company investing in an Indian factory, an Indian company borrowing abroad.
- Why does the central bank intervene under managed floating? Give one example. Answer: To prevent sharp, disruptive swings. If the rupee falls very fast, the RBI sells dollars from its reserves, increasing dollar supply and supporting the rupee.
- 'A balance of payments deficit is impossible in accounting terms, yet newspapers report BoP deficits.' Explain. Answer: In double-entry accounting every transaction has two sides, so the overall BoP always balances. Newspapers mean a deficit on the current account (or on current + capital excluding official reserves) — financed by running down reserves or by capital inflows.
Recap — the chapter in five lines
- BoP = current account (goods, services, income, transfers) + capital account (borrowings, investment, banking capital).
- BoT is goods only; BoP covers everything. BoP balances by double-entry; a "deficit" means an autonomous-transactions deficit.
- Fixed system: devaluation/revaluation by the central bank. Flexible system: depreciation/appreciation by the market.
- Flexible rate: demand for foreign exchange (imports, investment abroad) meets supply (exports, investment inflows).
- India: managed floating — market decides, RBI intervenes against sharp swings. Depreciation helps exporters, hurts importers, risks inflation.
