When it rises (₹80 → ₹85 per $), each dollar costs more rupees: the rupee has depreciated . When it falls, the rupee has appreciated .
Demand for dollars (payments abroad) Supply of dollars (receipts from abroad) Imports of goods and services Exports of goods and services Indians travelling or studying abroad Foreign tourists in India Indians investing abroad Foreign investment in India Repaying foreign loans, sending gifts abroad Remittances to India, borrowing from abroad Speculators expecting the dollar to rise
The demand curve slopes down : a cheaper dollar makes imports cheaper, so more dollars are wanted. The supply curve slopes up : a dearer dollar makes Indian goods cheaper for foreigners, so exports and dollar earnings rise.
Under a flexible (floating) rate, the market sets the rate where the dollars demanded equal the dollars supplied.
A rise in the demand for dollars, such as a costlier oil import bill, depreciates the rupee from ₹80 to ₹90. A rise in the supply of dollars, such as a surge of foreign investment, appreciates the rupee from ₹80 to ₹70. Depreciation makes exports cheaper abroad and imports dearer at home, which helps close a BoP deficit on its own. A floating rate needs no reserves to defend a level, but it can swing and make trade uncertain.
Example 1 · Who gains from depreciation
An exporter sells software worth 10 lakh dollars. Before payment, the rupee moves from ₹80 to ₹84 per dollar.
At ₹80: 10 lakh × 80 = ₹8 crore. At ₹84: 10 lakh × 84 = ₹8.4 crore.
The dollar's price rose by 4 ÷ 80 = 5%.
Answer The exporter earns ₹40 lakh more
Under a fixed rate, the government or central bank sets the rate and holds it by buying or selling foreign currency. Lowering the fixed value is devaluation ; raising it is revaluation . Under the gold standard each currency had a gold value; under Bretton Woods (1944–1971) currencies were pegged to the dollar, which was convertible into gold.
At the fixed ₹70, the central bank must sell $20 billion from reserves to meet the shortage AB. A fixed rate gives traders certainty but needs large reserves; if they run out, the country must devalue towards the market rate.
Floating rate Fixed rate Depreciation, appreciation Devaluation, revaluation Set by the market Set by the authority
The market sets the rate, but the central bank buys or sells dollars to stop sharp swings: sell dollars to support a falling rupee, buy them when inflows push the rupee up too fast. India moved to a market-determined rate in March 1993 and follows managed floating, with the RBI intervening to curb excessive volatility.
Higher ₹ per $ = rupee depreciation.
Payments abroad = demand for forex; receipts = supply.
Market moves: depreciation/appreciation. Government moves: devaluation/revaluation.
Rupee falling too fast: the RBI sells dollars.
Reading a higher number as a stronger rupee.
Calling foreign investment into India a demand for dollars.
Using "devaluation" for a market fall.
Thinking managed floating needs no reserves.

Demand for $: imports, travel, investment abroad
Supply of $: exports, tourists, investment into India

Systems
Flexible: market sets it
Fixed: authority sets it; devalue or revalue
Managed floating: market with intervention (India since 1993)

NTA's Economics syllabus is three courses: Introductory Microeconomics, Introductory Macroeconomics and Indian Economic Development, each split into units with a list of topics. It prints no chapters and no split of the 50 questions across the courses. So the areas here are NTA's three courses, and the chapters inside them are ours: a unit that covers several ideas, such as consumer behaviour and demand, is split into a chapter for each, so that a chapter can be practised in one sitting. All three courses are here.
