Why would a country that is good at making everything still choose to import some of it?
International trade theory and balance of payments accounting explain how countries exchange goods, services, and capital across borders. This lesson walks through why trade happens, and how a country tracks everything that crosses its own border.
Must Know · Learn why trade happens
1. Why does a country benefit from trade even if it’s good at everything?
Classical trade theory, built on comparative advantage, explains why countries benefit from international trade.
Even a country good at producing everything still gains from specialising in what it does relatively best, and trading for the rest. This is a genuinely counterintuitive insight.
Example: a skilled doctor who also types faster than anyone else still hires a secretary. Time spent typing is time not spent seeing patients, where the doctor’s advantage is far bigger.
2. What does “Most Favoured Nation” actually require?
The MFN (Most Favoured Nation) principle requires equal trade treatment among trading partners.
A country cannot quietly offer one trading partner a better tariff deal than another, without extending that same treatment more broadly.
Worked example. If Country A cuts its tariff on Country B’s steel to 5%, MFN generally requires Country A to offer that same 5% rate to every other WTO member it trades steel with too, not just to Country B. A free trade agreement is one of the recognised exceptions to this rule.
QUICK CHECK 1 OF 5 · TRUE OR FALSE
The Most Favoured Nation principle allows a country to freely offer one trading partner better terms than another.
MFN requires equal trade treatment among trading partners — a country generally cannot single out one partner for better terms without extending that same treatment more broadly.
3. What does the Balance of Payments actually record?
A country’s Balance of Payments (BoP) records all economic transactions between its residents and the rest of the world.
That includes trade in goods and services, but also capital flows like investment and loans — not just imports and exports.
Worked example. A country’s trade balance alone might show a deficit, exports below imports, and look alarming on its own. But its BoP might also show a large inflow of foreign investment covering that gap comfortably. Trade figures alone would miss that second, reassuring half of the story.

4. What does currency devaluation aim to do, and what backs India’s reserves?
Devaluation aims to make a country’s exports cheaper and imports more expensive, improving the trade balance.
India’s foreign exchange reserves are made up mainly of foreign currency assets, gold, and Special Drawing Rights (SDRs).
QUICK CHECK 2 OF 5 · TRUE OR FALSE
Currency devaluation aims to make a country’s exports cheaper and its imports more expensive.
That is exactly devaluation’s goal — cheaper exports and pricier imports, to help the trade balance.
5. What is SAFTA, and who administers India’s Foreign Trade Policy?
The South Asian Free Trade Area (SAFTA) aims to reduce trade barriers among South Asian countries.
India’s Foreign Trade Policy is administered by the Ministry of Commerce and Industry.
6. How does rupee depreciation affect trade?
A depreciating rupee generally makes India’s exports more competitive, but raises the cost of imports.
Worked example. If the rupee slides from ₹80 to ₹85 per US dollar, an Indian software export earning $100 now converts to ₹8,500 instead of ₹8,000, more competitive abroad in dollar terms. But an oil importer paying in dollars now needs more rupees for the same barrel, so fuel costs rise at home.
7. Is the rupee fully convertible?
India’s rupee is fully convertible on the current account, for trade and travel, but only partly convertible on the capital account.
See IndEco0136 — The Tarapore Committee and Capital Account Convertibility for the full picture.
8. Who actually owes India’s external debt, and in what currencies?
Government entities owe only about a fifth of India’s external debt. Most of it is owed by private-sector borrowers, not the government.
India’s external debt is not all in US dollars. Around 55% is USD-denominated, with the rest split across Indian rupees, Japanese yen, SDRs, and euros.
QUICK CHECK 3 OF 5 · TRUE OR FALSE
Most of India’s external debt is owed by government entities, not the private sector.
It’s the opposite. Government entities owe only about a fifth of India’s external debt — most of it is owed by private-sector borrowers.
9. What lowers India’s currency-crisis risk, and what raises it?
Foreign currency earnings from India’s IT sector and remittances from Indians abroad are steady inflows. They build up reserves and lower the risk of a currency crisis.
Exam trap: higher government expenditure works the other way. It tends to widen the fiscal and current account deficits together, raising currency-crisis risk instead of reducing it.
QUICK CHECK 4 OF 5 · TRUE OR FALSE
Higher government expenditure tends to lower currency-crisis risk by shrinking the current account deficit.
It does the opposite. Higher government expenditure tends to widen the fiscal and current account deficits together, raising currency-crisis risk.

10. Why is BoP accounting more revealing than trade figures alone?
BoP accounting reveals far more about an economy’s external health than trade figures alone. It captures capital flows and services too, not just goods.
11. What are the real trade-offs of currency devaluation?
Currency devaluation carries real trade-offs. It boosts exports, but also raises domestic prices for imported goods and inputs.
A country cannot devalue its way to a stronger economy for free — someone inside that economy pays more for anything imported.
12. What is “import cover,” and what isn’t it?
Import cover is the number of months of imports that a country’s foreign exchange reserves can pay for.
It signals how well a country can keep paying for imports if a shock cuts off other sources of foreign exchange.
Exam trap: import cover is not the ratio of imports to GDP, and not the ratio of exports to imports. It measures reserves against monthly import spending.
Example: India’s import cover stood at 9.8 months in September 2015. Crashing crude oil prices pushed projected import cover toward roughly 10.8 months by the end of 2015, since oil made up roughly a third of India’s total imports at the time. Cheaper oil sharply cut the import bill and lifted the cover ratio.
QUICK CHECK 5 OF 5 · TRUE OR FALSE
Import cover measures the ratio of a country’s exports to its imports.
It does not. Import cover measures a country’s foreign exchange reserves against its monthly import spending — how many months of imports those reserves could pay for.

13. Current Affairs: India’s Q4 FY26 current account surplus
Development On 8 June 2026, the RBI reported a current account surplus of $7.1 billion for Q4 FY 2025-26, equal to 0.7% of GDP. (Source: Business Standard)
Comparison This was down from a $13.7 billion surplus in Q4 FY 2024-25, a year earlier. (Source: Forbes India)
Full year For the full year FY26, the current account deficit widened to $25.2 billion. FY25’s full-year deficit had been $22.9 billion. (Source: Business Standard)
Services and remittances Net services receipts rose to $60.4 billion in Q4 FY26, up from $53.3 billion a year earlier. Remittances rose to $43.5 billion, up from $33.9 billion. (Source: Forbes India)

14. Exam Practice: NEER, REER, and trade competitiveness
Question UPSC (CSP) 2022 asked whether an increase in NEER indicates rupee appreciation, whether an increase in REER indicates improved trade competitiveness, and whether rising domestic inflation causes NEER and REER to diverge.
The correct answer is the first and third statements only. A rising REER actually signals worsening, not improving, trade competitiveness, since domestic goods grow relatively more expensive abroad.

15. Exam Practice: what devaluation necessarily does
Question UPSC (CSP) 2021 asked whether devaluation necessarily improves export competitiveness, increases the foreign value of the domestic currency, and improves the trade balance.
The correct answer is the first statement only. Devaluation necessarily cuts, not raises, the domestic currency’s foreign value, and need not improve the trade balance.

16. Exam Practice: a question UPSC dropped
Question UPSC (CSP) 2020 asked about the state of India’s international trade at the time. UPSC officially dropped this question from its answer key.
India’s current account briefly swung to a surplus just before the exam, likely making one statement debatable. The site’s own 2026 current account update, CA0019, shows the same pattern repeating.

19. Can you explain it without looking back?
Pause before opening each answer. Aim to explain the idea in your own words.
Think it through. Why does a country good at everything still gain from trading?
Show the explanation
Because specialising in what it does relatively best, and trading for the rest, still uses its time and resources more efficiently than trying to make everything itself.
Think it through. What does ‘import cover’ actually measure?
Show the explanation
How many months of imports a country’s foreign exchange reserves could pay for — not a ratio of imports to GDP or exports to imports.
Think it through. Name one thing that lowers India’s currency-crisis risk, and one that raises it.
Show the explanation
IT-sector foreign earnings and remittances lower it, by building reserves. Higher government expenditure raises it, by widening the fiscal and current account deficits together.
