Key concepts

Balance of payments: meaning and structure

NCERT section 6.1

The BoP records all economic transactions of a country's residents with the rest of the world in a year, on the double-entry principle: receipts (inflows of foreign exchange) are credits; payments are debits. In accounting terms the BoP always balances; "surplus" and "deficit" refer to autonomous transactions.

It has two main accounts, current and capital, plus errors and omissions (because recording is never complete) and the change in official reserves. NCERT notes that under the IMF's BPM6 the RBI also uses a three-account format (current, financial, capital), but continues to publish the old two-account format, which is what the book uses.

Worked example

Suppose an Indian company buys a factory in Germany. In which account of India's BoP is this recorded, and is it a credit or debit? [1 mark]

Try it first, then show the solutionSolution

1. Purchase of an asset abroad: capital account.
2. Foreign exchange flows out: debit.

Answer: Capital account, debit.

Current account and balance of trade

NCERT section 6.1.1

The current account records:

• Visible trade: exports and imports of goods. Their difference is the balance of trade (trade balance).
• Invisibles: (a) trade in services (transport, banking, insurance, software, tourism); (b) income: compensation of employees and investment income (interest, profits, dividends); (c) transfers: gifts, remittances, grants (one-way, nothing in return).

Current account balance = balance of trade + net invisibles. A current account deficit means the country spends abroad more than it earns; it must be financed by a capital account surplus or by using reserves.

Balance of trade covers goods only; current account balance covers goods, services, income and transfers.

Worked example

Suppose exports of goods are USD 400 million, imports of goods USD 550 million, net services USD 80 million, net income −USD 20 million and net transfers USD 50 million. Find the trade balance and the current account balance. [3 marks]

Try it first, then show the solutionSolution

1. Trade balance = 400 − 550 = −USD 150 million (deficit).
2. Net invisibles = 80 − 20 + 50 = USD 110 million.
3. Current account balance = −150 + 110 = −USD 40 million (deficit).

Answer: Trade deficit USD 150 million; current account deficit USD 40 million.

Capital account

NCERT section 6.1.2

The capital account records international transactions in assets (money, shares, bonds, land, factories, government debt). Purchase of a foreign asset is a debit (outflow); sale of a domestic asset to foreigners or borrowing from abroad is a credit (inflow).

Items: foreign direct investment (FDI, buying a lasting controlling stake), portfolio investment (buying shares and bonds without control), external commercial borrowings, external assistance, short-term debt, banking capital including non-resident deposits.

Surplus: capital inflows > outflows; deficit: inflows < outflows.

Worked example

Classify as current or capital account: (i) remittances sent home by Indian workers in the Gulf; (ii) a loan taken by an Indian firm from a foreign bank; (iii) software services sold abroad; (iv) a foreign institution buying shares on the Indian stock market. [2 marks]

Try it first, then show the solutionSolution

1. (i) Current (transfers).
2. (ii) Capital (borrowing).
3. (iii) Current (services).
4. (iv) Capital (portfolio investment).

Answer: (i) current; (ii) capital; (iii) current; (iv) capital.

BoP surplus and deficit; autonomous and accommodating items

NCERT section 6.1.3

Autonomous transactions are made for their own sake, such as profit or trade, independent of the BoP position; they are "above the line". Accommodating transactions are made to cover the gap left by autonomous ones; official reserve transactions (the central bank buying or selling foreign exchange) are the main accommodating item, "below the line".

• Overall balance = current account balance + capital account balance + errors and omissions.
• BoP deficit: overall balance < 0; reserves are run down (official reserve sale).
• BoP surplus: overall balance > 0; reserves rise.
• Balanced: overall balance = 0; no reserve change.

Balance of payments of an imaginary country (USD million)

Item	USD million
1. Exports of goods	400
2. Imports of goods	550
3. Trade balance (1 − 2)	(−) 150
4. Net invisibles: services 80, income (−) 20, transfers 50	110
5. Current account balance (3 + 4)	(−) 40
6. Capital account balance: FDI 30, portfolio 15, external commercial borrowing 10, banking capital 5	60
7. Errors and omissions	(−) 5
8. Overall balance (5 + 6 + 7)	15
9. Change in official reserves	Increase of 15

Worked example

Using the table above, find the overall balance and the change in official reserves. Is the BoP in surplus or deficit? [3 marks]

Try it first, then show the solutionSolution

1. Overall balance = −40 + 60 + (−5) = +USD 15 million.
2. Autonomous receipts exceed payments: BoP surplus.
3. Official reserves increase by USD 15 million (an accommodating item).

Answer: Surplus of USD 15 million; reserves rise by USD 15 million.

Foreign exchange rate; demand and supply of foreign exchange

NCERT section 6.2, 6.2.1

The foreign exchange rate is the price of one currency in terms of another, e.g. ₹80 per US dollar. The foreign exchange market (commercial banks, brokers, authorised dealers, monetary authorities) is worldwide.

Demand for foreign exchange arises to import goods and services, send gifts or remittances abroad, buy foreign assets, and speculate. It slopes downward: a higher rupee price of the dollar makes imports dearer, so less foreign exchange is demanded.

Supply of foreign exchange comes from exports, transfers received and foreigners buying domestic assets (and speculation). It usually slopes upward: a higher rupee price of the dollar makes Indian goods cheaper for foreigners, raising exports and the supply of dollars.

Worked example

Suppose more Indian students go abroad for higher studies. What happens to the demand for foreign exchange and, in a flexible system, to the rupee? [3 marks]

Try it first, then show the solutionSolution

1. Fees and living costs abroad must be paid in foreign currency.
2. Demand for foreign exchange shifts right.
3. The rupee price of foreign currency rises: the rupee depreciates.

Answer: Demand for foreign exchange rises; the rupee depreciates.

Flexible exchange rate: determination, depreciation and appreciation

NCERT section 6.2.2

Under a flexible (floating) system, the exchange rate is set where the demand curve for foreign exchange cuts the supply curve, without central bank intervention.

• An increase in demand for foreign exchange (e.g. more imports, more travel abroad) raises the rate: the domestic currency depreciates (more rupees per dollar).
• An increase in supply (e.g. more exports or foreign investment) lowers the rate: the domestic currency appreciates.

NCERT also notes that speculation can move rates: if people expect a currency to rise, they buy it now, pushing its value up. In the long run, purchasing power parity suggests exchange rates move so that the same goods cost the same in each country.

Worked example

Suppose a shirt costs USD 10 in the USA and ₹600 in India. What exchange rate makes the prices equal? If prices then rise by 10% in India and by 32% in the USA, what is the new rate, and which currency has depreciated? [3 marks]

Try it first, then show the solutionSolution

1. Equal prices: ₹600 = USD 10 → ₹60 per dollar.
2. New prices: ₹660 in India; USD 13.20 in the USA.
3. 660 ÷ 13.20 = ₹50 per dollar: fewer rupees per dollar, so the dollar has depreciated and the rupee appreciated.

Answer: ₹60 per dollar, then ₹50 per dollar; the dollar depreciates.

Fixed exchange rate: devaluation and revaluation

NCERT section 6.2.2 (fixed exchange rates)

Under a fixed system the government fixes the exchange rate. To hold a rate above the market rate, the central bank must buy the excess supply of foreign currency (reserves rise); to hold it below, it must sell foreign currency from reserves to meet excess demand. If reserves run out, a black market may appear.

Devaluation: the government raises the exchange rate (domestic currency made cheaper) in a fixed system. Revaluation: the government lowers it. Depreciation and appreciation are market-driven changes in a flexible system.

Worked example

Suppose the market rate is ₹50 per dollar but the government fixes it at ₹70 to boost exports. What happens in the market and what must the central bank do? [3 marks]

Try it first, then show the solutionSolution

1. At ₹70, Indian goods are cheaper abroad, so supply of dollars exceeds demand.
2. The RBI must buy the excess dollars with rupees to hold the rate.
3. Its foreign exchange reserves keep rising as long as it intervenes.

Answer: Excess supply of dollars; RBI buys dollars and accumulates reserves.

Merits and demerits; managed floating

NCERT section 6.2.3, 6.2.4

Basis	Fixed exchange rate	Flexible exchange rate
Stability	Stable rates encourage trade and investment	Rates can fluctuate, adding uncertainty
Reserves	Needs large reserves to defend the rate	No need for large reserves
BoP adjustment	Deficits must be met from reserves	Rate movements correct surpluses and deficits automatically
Monetary policy	Constrained by the need to defend the rate	Independent monetary policy
Speculation	Open to speculative attacks when reserves look inadequate (as before the collapse of the Bretton Woods system)	Speculation can make rates volatile

Managed floating (dirty floating) mixes the two: the rate is market-determined, but the central bank buys or sells foreign currency to moderate large movements. Official reserve transactions are therefore not zero.

Worked example

Suppose the rupee falls sharply in a week because of panic selling, and the RBI sells dollars from its reserves to steady it. Which system is this, and why does the RBI intervene? [3 marks]

Try it first, then show the solutionSolution

1. The rate is market-set but the central bank intervenes: managed floating.
2. Selling dollars increases their supply and limits the rupee's fall.
3. It reduces volatility that would hurt trade and inflation.

Answer: Managed floating; the RBI intervenes to moderate excessive volatility.

Where students lose marks in Open Economy Macroeconomics

The slips examiners see most often, and what to write instead.

• ✗Mistake: Treating balance of trade and current account balance as the same

  Both concern trade.

  ✓Do this: BoT is goods only; CAB adds services, income and transfers.

  Usually costs: 1 mark.

• ✗Mistake: Calling a market-driven fall of the rupee "devaluation"

  Loose newspaper usage.

  ✓Do this: Devaluation is a government act in a fixed system; market falls are depreciation.

  Usually costs: 1 mark.

• ✗Mistake: Putting remittances in the capital account

  Money moves across borders.

  ✓Do this: Remittances are unilateral transfers: current account.

  Usually costs: 1 mark.

• ✗Mistake: Reading a higher ₹/USD figure as rupee appreciation

  Bigger number seems stronger.

  ✓Do this: More rupees per dollar means the rupee is weaker (depreciated).

  Usually costs: 1-2 marks.

• ✗Mistake: Writing about Box 6.2 international experience

  It is in older books.

  ✓Do this: Box 6.2 was dropped by NCERT and is not in the syllabus.

  Usually costs: Time lost.

   Answer

   (b)

3. Q3 · 3 marks · Short answerBoard level

   Distinguish between autonomous and accommodating transactions.

   Hint

   Purpose and position.

   Answer

   Autonomous: made for their own sake (trade, profit), independent of the BoP, "above the line". Accommodating: made to cover the BoP gap, mainly official reserve transactions, "below the line".

4. Q4 · 3 marks · Short answerBoard level

   State three sources of demand for and three sources of supply of foreign exchange.

   Hint

   Imports vs exports.

   Answer

   Demand: imports, remittances or gifts sent abroad, purchase of foreign assets (also speculation). Supply: exports, transfers received, foreigners buying domestic assets (also speculation).

5. Q5 · 3 marks · Short answerHarder board level

   Suppose exports of goods are USD 300 million, imports USD 380 million, net invisibles USD 50 million, and the capital account surplus is USD 45 million, with errors and omissions zero. Find the current account balance and overall balance.

   Hint

   Trade balance first.

   Answer

   Trade −80; CAB = −80 + 50 = −30; overall = −30 + 45 = +USD 15 million (surplus; reserves rise).

6. Q6 · 4 marks · Short answerHarder board level

   Explain how the exchange rate is determined under a flexible system, and what happens when imports increase.

   Hint

   Diagram in words.

   Answer

   The rate is where demand for foreign exchange equals supply. More imports raise demand for dollars, shifting DD right; at the old rate there is excess demand, so the rate rises (rupee depreciates) to a new equilibrium.

7. Q7 · 3 marks · Short answerHarder board level

   Suppose the government fixes the rate below the market rate. What problem arises and how is it handled?

   Hint

   Excess demand.

   Answer

   At a lower ₹/USD rate, demand for dollars exceeds supply. The central bank must sell dollars from reserves; if reserves run short, a black market for dollars may develop.

8. Q8 · 1 mark · Assertion-reasonHOTS / competency

   Assertion (A): Under a flexible exchange rate system, official reserve transactions are zero.
   Reason (R): The central bank does not intervene in the foreign exchange market.
   (a) Both true and R explains A (b) Both true, R does not explain A (c) A true, R false (d) A false, R true

   Hint

   Pure float.

   Answer

   (a)

9. Q9 · 4 marks · Short answerHOTS / competency

   Suppose remittances from Indians abroad rise sharply. Trace the effect on India's current account, the supply of dollars and the rupee under managed floating.

   Hint

   Transfers are current account credits.

   Answer

   Remittances are current-account transfers (credit), improving the current account. They raise the supply of dollars, so the rupee tends to appreciate; under managed floating the RBI may buy dollars to limit the rise, adding to reserves.

10. Q10 · 3 marks · Short answerHarder board level

    Explain two merits of a flexible exchange rate system.

    Hint

    Reserves and adjustment.

    Answer

    No need for large foreign exchange reserves; automatic correction of BoP surpluses and deficits through rate movements (also independent monetary policy).
