Basis of International Trade and Balance of Trade (Class 12 Geography, Chapter 8)

Updated 16 October 2026 · Fact-checked

International trade rests on five bases: differences in national resources, population factors, stage of economic development, extent of foreign investment and transport. Balance of trade compares the value of a country's exports and imports: exports above imports give a favourable (positive) balance; imports above exports give an unfavourable (negative) balance.

Compare the two scales: whichever of exports or imports is heavier decides whether the balance of trade is favourable or unfavourable.

Understand Basis of Trade and Balance of Trade

Why this topic matters. The bases of trade come as matching items and 5-mark answers, balance of trade as a definition or a short numerical, and the history of trade as a sequencing MCQ.

1. What trade is. Trade is the voluntary exchange of goods and services; two parties are needed and it is mutually beneficial. International trade is exchange among countries across national boundaries; countries trade for goods they cannot produce or can buy more cheaply elsewhere.

The first form was barter (direct exchange). The Jon Beel Mela at Jagiroad, about 35 km from Guwahati, held every January after harvest, is possibly the only fair in India where barter survives.
Money overcame barter's difficulties. Before coins and notes, rare objects such as cowrie shells, salt, cattle and metals served as money. 'Salary' comes from the Latin salarium, payment by salt.

2. History of international trade (in sequence).

1. Silk Route: about 6,000 km, linking Rome and China; silk, wool and precious metals traded via India, Persia and Central Asia.
2. After the Roman Empire broke up, European commerce grew in the 12th-13th centuries with ocean-going warships; the Americas were discovered.
3. From the 15th century, European colonialism and the slave trade: Portuguese, Dutch, Spaniards and British shipped Africans to the Americas. It lasted over two hundred years, abolished in Denmark (1792), Great Britain (1807), U.S.A. (1808).
4. After the Industrial Revolution, industrial nations imported raw materials and exported finished goods; later in the 19th century they became each other's main customers.
5. In the World Wars, trade taxes and quantitative restrictions came for the first time; after the wars GATT (later the WTO) helped reduce tariffs.

3. Why trade exists. Trade results from specialisation and division of labour. It rests on comparative advantage, complementarity and transferability of goods and services, and should benefit both partners.

4. The five bases of international trade.

Difference in national resources (geology, relief, soil, climate): geological structure sets the mineral base and crop diversity (lowlands farm, mountains draw tourists); minerals are unevenly spread and drive industry; climate decides products (wool in cold regions; bananas, rubber, cocoa in the tropics).
Population factors: cultural crafts are prized (Chinese porcelain and brocades, Iranian carpets, North African leather, Indonesian batik); size: densely populated countries trade more internally than externally; standard of living sets demand for imported goods.
Stage of economic development: agricultural countries exchange farm produce for manufactures; industrial nations export machinery and import food and raw materials.
Extent of foreign investment: capital from industrial nations develops mining, oil drilling, heavy engineering, lumbering and plantations in developing countries, raising trade both ways.
Transport: once only gems, silk and spices travelled far; rail, ocean and air transport plus refrigeration and preservation gave trade spatial expansion.

5. Balance of trade. Records the value of goods and services a country imports and exports.

Exports > imports: positive or favourable balance.
Imports > exports: negative or unfavourable balance; the country spends more than it earns, which can exhaust its financial reserves.
Balance of trade = value of exports - value of imports.

6. Types of trade.

Bilateral: two countries agree to trade specified commodities with each other.
Multilateral: one country trades with many partners and may give some the status of Most Favoured Nation (MFN).

How to answer Basis of Trade and Balance of Trade questions

Expect matching or odd-one-out MCQs on bases, a sequencing MCQ on history, a short balance-of-trade sum, and a 5-mark answer on bases.

1For a balance-of-trade sum, subtract imports from exports, keep the units and sign, and name the balance favourable or unfavourable.
2For a 5-mark 'bases' answer, take the five bases as headings and give one example each (cocoa, batik, MFN is not a base).
3For history, keep the order: Silk Route, European commerce, colonial and slave trade, Industrial Revolution, World Wars and GATT.
4Use comparative advantage, complementarity and transferability when asked why trade exists.
5Explain why a negative balance is harmful: spending exceeds earnings, so reserves run down.

Basis of Trade and Balance of Trade in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Favourable or unfavourable balance

Suppose a country sells goods worth ₹ 4,20,000 crore abroad in a year and buys goods worth ₹ 5,10,000 crore.

Find its balance of trade and say what it means.

Try it first, then show the solutionSolution

Balance = exports - imports = 4,20,000 - 5,10,000.
= -90,000 crore.
Negative, so unfavourable: the country spends more than it earns from trade.

Answer: Balance of trade = -₹ 90,000 crore, an unfavourable balance; if it continues, the country's financial reserves will be used up.

Memory hook: Exports minus imports: minus is bad news.

Population size and external trade

Suppose two countries grow the same amount of rice, but one has five times as many people.

Which is more likely to export rice?

Try it first, then show the solutionSolution

Densely populated countries consume most of their own farm and factory output.
So they have large internal trade but little external trade.

Answer: The less populated country is more likely to export rice; the crowded one eats most of what it grows.

Memory hook: Many mouths, little export.

Basis of Trade and Balance of Trade: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Balance of trade sum · 1 mark · MCQBoard level

A country's exports are worth US $260 bi l l i o nan d i t s im p or t s U S$ 215 billion. Its balance of trade is:
(A) -45 billion, unfavourable
(B) +45 billion, favourable
(C) +475 billion, favourable
(D) -475 billion, unfavourable

Try it first, then show the solutionSolution

Exports - imports = 260 - 215 = +45 billion; exports exceed imports, so favourable (1 mark).

Answer: (B) +45 billion, favourable

Example 2: Assertion and reason on early long-distance trade · 1 mark · Assertion-reasonHarder board level

Assertion (A): In olden times, only high-value goods such as gems, silk and spices were traded over long distances.
Reason (R): A lack of adequate and efficient means of transport restricted most trade to local areas.
(A) Both (A) and (R) are true and (R) is the correct explanation of (A).
(B) Both (A) and (R) are true but (R) is not the correct explanation of (A).
(C) (A) is true but (R) is false.
(D) (A) is false but (R) is true.

Try it first, then show the solutionSolution

NCERT (transport as a base of trade): poor transport kept trade local, so only goods valuable enough to bear the cost and risk, such as gems, silk and spices, went far; R explains A (1 mark).

Answer: (A) Both (A) and (R) are true and (R) is the correct explanation of (A).

Example 3: A balance that changes sign · 3 marks · Short answerBoard level

Five years ago, country X exported goods worth ₹ 300 crore and imported goods worth ₹ 400 crore. Now its exports are worth ₹ 450 crore, while imports are still ₹ 400 crore. Work out its balance of trade at both dates, name each, and explain what the change means for its financial reserves. (3 marks)

Try it first, then show the solutionSolution

Then: 300 - 400 = -₹ 100 crore, a negative or unfavourable balance (1 mark).
Now: 450 - 400 = +₹ 50 crore, a positive or favourable balance (1 mark).
Earlier it spent more on buying goods than it earned by selling, which over time exhausts reserves; now it earns more than it spends, so the drain on reserves has stopped (1 mark).

Answer: Five years ago the balance was 300 - 400 = -₹ 100 crore, a negative or unfavourable balance of trade. Now it is 450 - 400 = +₹ 50 crore, a positive or favourable balance. Earlier the country was spending more on buying goods than it earned by selling its goods, which would ultimately exhaust its financial reserves; with exports now above imports, it earns more than it spends on trade, so its reserves are no longer being run down.

Example 4: Spotting the bases in a trade pattern · 3 marks · Short answerHarder board level

A cold country exports woollens and imports cocoa; it also buys carpets from Iran. Identify the two bases of international trade at work and explain each. (3 marks)

Try it first, then show the solutionSolution

Climate, under difference in national resources: wool can be produced in cold regions, while cocoa grows only in tropical regions, so each side sells what the other cannot produce (1.5 marks).
Cultural factors, under population factors: distinctive crafts such as Iranian carpets are valued the world over, so they are imported even by countries that make textiles (1.5 marks).

Answer: Woollens for cocoa reflects climate, part of the difference in national resources: climate decides which plants and animals a region can support, so wool comes from cold regions and cocoa from tropical regions, and each country buys what it cannot produce. Iranian carpets reflect cultural factors, part of population factors: distinctive art and craft develops in certain cultures and is valued the world over, so such goods are traded widely.

Example 6: HOTS: bases at work · 5 marks · Long answerHOTS / competency

"A tropical, densely populated, agricultural country and a cold, industrialised, capital-rich country will trade with each other." Use the bases of international trade to explain what each would export and why. (5 marks)

Try it first, then show the solutionSolution

Resources and climate: tropical country exports bananas, rubber, cocoa; cold country exports wool, minerals or machinery (1 mark).
Population: the crowded country consumes much at home; low standard of living limits costly imports (1 mark).
Stage of development: agro products exchanged for manufactured goods and machinery (1 mark).
Foreign investment: capital-rich country invests in plantations or mining, ensuring imports and markets (1 mark).
Transport: refrigeration and ocean transport let perishables move; conclusion on complementarity (1 mark).

Answer: The two countries are complementary.

Resources: climate decides products, so the tropical country can export bananas, rubber and cocoa, while the cold country can export goods such as wool and the manufactures its minerals support.

Population: the tropical country is densely populated, so much of its output is consumed at home; with a lower standard of living, only some can afford costly imports.

Stage of development: an agricultural country exchanges farm produce for manufactured goods, while the industrial nation exports machinery and finished products and imports food and raw materials.

Foreign investment: the capital-rich country may invest in plantations or mining in the tropical country, which secures its supply of food and minerals and creates a market for its finished goods, raising trade both ways.

Transport: modern ocean transport with refrigeration lets even perishable tropical produce travel far.

So specialisation based on these factors makes trade mutually beneficial, as the principle of comparative advantage predicts.

Q5 · 3 marks · Short answerHOTS / competency
Suppose a developing country with rich iron ore but little capital wants to raise its exports. Which base of trade can help it, and how? (3 marks)
Hint
Capital from abroad.
Answer
Extent of foreign investment. Developing countries lack the capital for mining and heavy engineering, so investment from industrial nations can develop the iron ore mines. The investors secure a supply of minerals, and the country earns from exports and becomes a market for their finished goods; this cycle raises the volume of trade.
Q6 · 3 marks · Short answerHarder board level
How has transport changed the nature of international trade over time? (3 marks)
Hint
Then high-value only; now everything.
Answer
In earlier times inadequate transport kept trade local, and only high-value goods such as gems, silk and spices travelled long distances, as on the Silk Route. The spread of rail, ocean and air transport and better refrigeration and preservation have expanded trade spatially, so bulky and perishable goods now move worldwide.
Q7 · 5 marks · Long answerHOTS / competency
"The history of international trade is also a history of inequality." Examine the statement. (5 marks)
Hint
Slave trade, colonial pattern, raw materials vs finished goods.
Answer
Long-distance trade began with luxuries on the 6,000 km Silk Route between Rome and China, when only the rich bought costly goods. From the 15th century, European colonialism brought the slave trade: Portuguese, Dutch, Spanish and British traders forcibly shipped Africans to work American plantations, a lucrative business for over two hundred years until abolition in Denmark (1792), Great Britain (1807) and the U.S.A. (1808). After the Industrial Revolution, industrial nations imported raw materials and exported value-added finished goods back to non-industrial nations, while the value of primary goods fell relative to manufactures. In the World Wars, trade taxes and restrictions appeared; only after the wars did GATT begin cutting tariffs. So trade did spread goods and wealth, but for long periods the gains went mainly to the powerful, which supports the statement.

Basis of Trade and Balance of Trade: frequently asked questions

Under which base of international trade does climate fall?

Difference in national resources, together with geological structure and mineral resources. NCERT gives five bases in all: national resources, population factors, stage of economic development, extent of foreign investment and transport.

Does a zero balance of trade mean a country does not trade?

No. It only means the value of exports equals the value of imports; the country may still trade heavily in both directions.

Is Most Favoured Nation status a base of international trade?

No. MFN is a status a country may grant some partners in multilateral trade; it is not one of the five bases.

Is international trade meant to benefit only the exporting country?

No. NCERT says trade based on specialisation, comparative advantage, complementarity and transferability should, in principle, be mutually beneficial to the trading partners.
