Balance of Payments and Exchange Rates for CA Foundation

Updated 1 October 2026 · Fact-checked

The balance of payments (BOP) is a systematic record of all economic transactions between a country's residents and the rest of the world in a year. It has a current account and a capital account. Exchange rates are set by demand and supply of foreign currency. Solve MCQs by classifying each transaction and its direction.

Understand Balance of Payments and Exchange Rates

The balance of payments (BOP) is a record of all economic transactions between residents of a country and the rest of the world over a period, usually a year. It uses double-entry bookkeeping. Every transaction has a credit and a debit side, so the BOP always balances in the accounting sense.

A credit (receipt) is an inflow of foreign exchange: exports, income received from abroad, or foreign investment coming in. A debit (payment) is an outflow: imports, income paid abroad, or investment going out.

The current account records trade in goods (visible items), trade in services and other invisibles, primary income (such as interest, profits and wages earned abroad) and secondary income (such as remittances and gifts). The capital account (together with the financial account in the modern format) records changes in assets and liabilities: foreign direct investment, portfolio investment and external borrowings.

Changes in foreign exchange reserves are not an autonomous capital flow. They are an accommodating or balancing item. Reserves are drawn down or built up to finance any overall surplus or deficit in the other accounts.

Balance of trade (BOT) is narrower. It covers only exports and imports of goods. BOP covers goods, services, income, transfers and capital flows. A country can have a trade deficit and still have a BOP surplus if capital inflows are large.

The exchange rate is the price of one currency in terms of another. In a flexible system it is set where demand for foreign currency equals its supply. Demand comes from imports, foreign travel and investment abroad. Supply comes from exports, remittances and foreign investment inflows. If demand rises, the foreign currency becomes costlier and the rupee depreciates. If supply rises, the rupee appreciates. In a fixed system the government or central bank sets the rate. In a managed float the market sets it, with central bank intervention to limit sharp swings.

A weaker rupee makes exports cheaper for foreigners and imports costlier for Indians. A stronger rupee does the opposite.

Key formulas to remember

Balance of trade: BOT = Value of exports of goods − Value of imports of goods; Only visible items. Positive is surplus, negative is deficit.
Current account balance: CAB = Trade balance (goods) + Net services + Net primary income + Net secondary income; Net means receipts minus payments.
Overall BOP: Overall balance = Current account balance + Capital and financial account balance (before reserve changes); Reserve changes are the accommodating item. An overall deficit is financed by drawing down reserves or by borrowing.
Accounting identity: Total credits = Total debits (including accommodating items such as reserve changes, and errors); BOP always balances in accounting terms once accommodating items are included. Disequilibrium refers to autonomous items.
Equilibrium exchange rate: Demand for foreign currency = Supply of foreign currency; Flexible-rate system.
Rupee depreciation: Rupee depreciates when more rupees are needed per unit of foreign currency (e.g. ₹80 per $ to ₹84 per $); A higher rupee price of the dollar means a weaker rupee.

How to solve Balance of Payments and Exchange Rates questions

Use this method for any MCQ on BOP, trade balance or exchange rates.

1Identify what is asked: balance of trade, current account, capital account, overall BOP, or an exchange rate effect.
2For a transaction, decide if it is goods, services, income, transfer or capital. Goods and services belong to the current account (goods alone to BOT).
3Decide the direction. Money coming in is a credit. Money going out is a debit.
4For calculations, add the credits and subtract the debits within the required account only. Do not mix goods with services unless asked.
5For exchange rate questions, find which side (demand or supply of foreign currency) shifts, and whether the foreign currency becomes costlier or cheaper.
6Translate the result: costlier foreign currency means the rupee depreciates, exports become cheaper abroad and imports costlier at home.
7Check the answer against each option, eliminate those with the wrong sign or wrong account, and pick the one remaining.

Quickest way: Sign-and-account check

When to use it: Use when the question lists items and asks for a balance, or asks the effect of a change in exchange rate.

Underline the account asked for. Strike out every item that belongs to another account.
Write + for receipts and − for payments next to each remaining item, then total them.
Check sign first. If the result is a deficit, drop every positive option at once.
For exchange rates, remember: more demand for foreign currency means a weaker rupee; more supply means a stronger rupee.
If a question needs a definition you are unsure of, skip it and return. A wrong answer costs 0.25 marks.

Common mistakes in Balance of Payments and Exchange Rates

Treating balance of trade and balance of payments as the same thing.
Both words sound alike and both involve exports and imports.
Fix: BOT is goods only. BOP covers goods, services, income, transfers and capital flows.
Including services in balance of trade.
Students think trade means every export and import.
Fix: In the BOT, count only visible goods. Services are invisibles and sit in the current account.
Placing remittances or gifts in the capital account.
Money flows in, so it feels like a capital flow.
Fix: Remittances are one-way transfers without a repayment obligation. They go in the current account as secondary income.
Reversing depreciation and appreciation.
A bigger number like ₹84 per $ looks like a gain.
Fix: If more rupees are needed to buy one dollar, the rupee is weaker, so it has depreciated.
Saying BOP can never be in deficit because it always balances.
Mixing the accounting identity with economic disequilibrium.
Fix: The BOP always balances in the accounting sense once accommodating items (reserve drawdown or borrowing) are included. A deficit means autonomous receipts fall short of autonomous payments.
Treating foreign investment inflow as an import or export.
Inflows are confused with trade flows.
Fix: Investment inflows are capital account credits. Trade means goods and services only.

Worked examples

Example 1

In a year a country's exports of goods were ₹5,00,000 crore and imports of goods were ₹7,20,000 crore. Net services receipts were ₹2,10,000 crore, and net primary and secondary income was a net receipt of ₹60,000 crore. What is the current account balance?
(A) Deficit of ₹50,000 crore
(B) Deficit of ₹1,50,000 crore
(C) Surplus of ₹50,000 crore
(D) Deficit of ₹2,20,000 crore

Show the solution

Trade balance = 5,00,000 − 7,20,000 = −2,20,000 (deficit).
Add net services: −2,20,000 + 2,10,000 = −10,000.
Add net income and transfers: −10,000 + 60,000 = +50,000.
The current account is a surplus of ₹50,000 crore.

Answer: (C) Surplus of ₹50,000 crore

Example 2

The rupee moves from ₹80 per US dollar to ₹85 per US dollar. Which statement is correct?
(A) The rupee has appreciated and imports become cheaper
(B) The rupee has depreciated and Indian exports become cheaper for foreign buyers
(C) The rupee has depreciated and imports become cheaper
(D) The rupee has appreciated and Indian exports become cheaper for foreign buyers

Show the solution

Earlier, $1 cost ₹80. Now $1 costs ₹85. More rupees are needed per dollar.
So the rupee has depreciated. This rules out A and D.
A dollar buyer now pays fewer dollars for the same rupee-priced Indian goods. Exports become cheaper abroad.
Imports priced in dollars cost more rupees, so C is wrong.

Answer: (B) The rupee has depreciated and Indian exports become cheaper for foreign buyers

Example 3

Which of the following is recorded in the current account of India's balance of payments?
(A) Foreign direct investment into India
(B) Remittances sent by Indians working abroad to their families in India
(C) Loans taken by India from the World Bank
(D) Purchase of Indian shares by foreign portfolio investors

Show the solution

FDI, external loans and portfolio investment all change assets or liabilities, so they are capital or financial account items. This rules out A, C and D.
Remittances are one-way transfers with no repayment. They are secondary income in the current account.

Answer: (B) Remittances sent by Indians working abroad to their families in India

Exam tips

Questions often ask for the classification of one transaction. Learn the five buckets: goods, services, income, transfers, capital.
Expect the contrast between balance of trade and balance of payments. Remember goods only versus everything.
For exchange rate questions, check the direction of the rate quote before choosing depreciation or appreciation.
Know the broad corrections for a deficit: export promotion, import curbs, exchange rate adjustment and attracting capital inflows.
Do not guess on close options. Each wrong answer costs 0.25 marks.

Practice questions from International Trade

Balance of Payments and Exchange Rates: frequently asked questions

What is the difference between balance of trade and balance of payments?

Balance of trade records only exports and imports of goods. Balance of payments records all economic transactions with the rest of the world, including services, income, transfers and capital flows.

What is the difference between the current account and the capital account?

The current account records trade in goods and services, income and transfers. The capital account records flows that change a country's assets and liabilities, such as investment and borrowing. Current account items are about income and spending. Capital items are about financial claims.

How is the exchange rate determined in a flexible system?

It is set where demand for foreign currency equals its supply. Imports and investment abroad raise demand. Exports, remittances and foreign investment inflows raise supply. A shift in either changes the rate.

What causes BOP disequilibrium and how is it corrected?

Causes include high imports, weak exports, falling capital inflows, inflation at home and sudden global shocks. Corrections include export promotion, import controls, adjusting the exchange rate, controlling domestic inflation and attracting foreign capital.
