Exchange rate questions turn on a small set of definitions that candidates routinely mix up — depreciation against devaluation, appreciation against revaluation, and which system India actually follows. Add the composition of the foreign exchange reserves and the terms around convertibility, and the topic is complete. This post sorts out each pair, covers the reserves, and ends with 15 previous year questions.
Key Points (Quick Revision)
- India follows a managed floating exchange rate system
- Depreciation is market-driven; devaluation is a deliberate government decision
- Forex reserves have four parts — foreign currency assets, gold, SDRs and the IMF reserve position
- Foreign currency assets form the largest share of the reserves
- The rupee is fully convertible on the current account but only partially on the capital account
1. Exchange rate systems
| System | How the rate is set |
|---|---|
| Fixed | The government or central bank fixes the rate and defends it |
| Floating or flexible | Demand and supply in the market decide the rate, with no intervention |
| Managed floating | The market decides, but the central bank intervenes to smooth sharp swings. This is India's system |
India follows a managed float, sometimes described as a dirty float. The RBI does not fix a target rate, but it buys and sells dollars to curb excessive volatility. A question asking which system India follows expects "managed floating", not "floating" and not "fixed".
2. The four terms candidates mix up
| Term | What happens | Under which system |
|---|---|---|
| Depreciation | The rupee loses value against a foreign currency | Market-driven, under a floating or managed float |
| Appreciation | The rupee gains value | Market-driven |
| Devaluation | The rupee's value is deliberately reduced by the authorities | A policy decision, under a fixed system |
| Revaluation | The value is deliberately raised by the authorities | A policy decision |
The distinction is who caused it. If the market moved the rate, it is depreciation or appreciation. If the government or central bank announced a change, it is devaluation or revaluation. India's rupee was devalued in 1949, 1966 and 1991; what happens to it now on an ordinary day is depreciation or appreciation.
The effects are asked too. A weaker rupee makes exports cheaper for foreign buyers and imports costlier, which helps exporters and raises the import bill, particularly for crude oil. A stronger rupee does the reverse.
A related pair worth keeping straight: the nominal exchange rate is the rate you see quoted, while the real effective exchange rate adjusts for inflation and trade weights against a basket of currencies.
3. What the foreign exchange reserves are made of
India's forex reserves, held and managed by the RBI, have four components, and the list is asked as a set.
| Component | What it is |
|---|---|
| Foreign Currency Assets | Holdings in foreign currencies, mainly government securities and deposits abroad. The largest share by far |
| Gold | Gold held by the RBI as part of the reserves |
| Special Drawing Rights (SDRs) | A reserve asset created by the IMF, based on a basket of major currencies |
| Reserve Tranche Position | India's reserve position with the IMF, which can be drawn without conditions |
Foreign Currency Assets form the largest component, which is the fact asked most often. SDRs are created by the IMF, not by the RBI, and are sometimes called paper gold — another regularly asked description.
Reserves matter because they let the RBI intervene to steady the rupee, cover imports, and meet external obligations. The measure usually quoted is the import cover — how many months of imports the reserves could pay for.
The total size of the reserves and the share of each component change every week, since the RBI publishes updated figures regularly. Learn the four components and which is largest; look up any actual number only shortly before your examination.
4. Convertibility and related terms
| Term | What it means |
|---|---|
| Current account convertibility | Freedom to convert rupees for trade, travel, education and remittances. India allows this fully |
| Capital account convertibility | Freedom to convert for investment and asset purchases abroad. India allows this only partially |
| Hard currency | A widely accepted, stable currency such as the US dollar |
| Soft currency | A currency not widely accepted for international settlement |
| Hot money | Short-term foreign capital that can leave quickly |
| LERMS | The Liberalised Exchange Rate Management System introduced in the early 1990s, a step towards the present arrangement |
| Tarapore Committee | Examined the move towards capital account convertibility |
Full on the current account, partial on the capital account is the exact form the convertibility question takes. The reasoning behind the caution on the capital side is that free movement of short-term capital can destabilise a currency quickly, which is what hot money describes.
The Tarapore Committee is the name attached to capital account convertibility in exam material, and it is asked as a committee-to-subject pairing rather than for its recommendations.

6. How to revise this topic
Fix the four terms first, because they carry most of the questions and candidates mix them up more than anything else here. The test is simply who caused the change — the market gives depreciation and appreciation, the authorities give devaluation and revaluation.
Then learn the four reserve components as a set, and remember which is largest. SDRs belong to the IMF, not the RBI, and the phrase paper gold attaches to them.
Keep every number out of your notes. Reserve totals change weekly and the rupee moves daily, so learn the definitions and the direction of each effect, and look up a current figure only shortly before the examination.
7. Frequently Asked Questions
Which exchange rate system does India follow?
A managed floating system, sometimes called a dirty float. The market sets the rate, but the RBI intervenes by buying and selling foreign currency to smooth sharp swings rather than to defend a fixed level.
What is the difference between depreciation and devaluation?
Depreciation is a fall in the currency's value caused by market forces under a floating system. Devaluation is a deliberate reduction announced by the government or central bank under a fixed system. The test is who caused it.
What are the four components of India's forex reserves?
Foreign Currency Assets, gold, Special Drawing Rights and the Reserve Tranche Position with the IMF. Foreign Currency Assets form by far the largest share.
What are Special Drawing Rights?
A reserve asset created by the IMF, based on a basket of major currencies, allotted to member countries. They are sometimes described as paper gold, which is how questions often refer to them.
Is the Indian rupee fully convertible?
On the current account yes, covering trade, travel, education and remittances. On the capital account only partially, because free movement of short-term capital can destabilise a currency quickly.
