The Real Exchange Rate: What Your Rupee Actually Buys
Think about this. You walk into a shop in Delhi and see a pair of sneakers for ₹4,000. Your cousin in New York sends you a photo of the same sneakers — they cost $80 there. Which is cheaper? You can't just compare ₹4,000 and $80. You need to convert one into the other using the exchange rate.
If 1 US dollar = ₹83, then $80 = ₹6,640. So the sneakers in Delhi (₹4,000) are cheaper. That's the nominal comparison — just using the market exchange rate.
But what if you're not comparing sneakers? What if you're comparing an entire haircut in India (₹200) versus a haircut in the US ($30)? At ₹83 per dollar, that $30 haircut equals ₹2,490. The Indian haircut is far cheaper. But does that mean everything in India is cheaper? Not exactly. Some things — like imported electronics or petrol — might cost more in India than abroad.
This is where the real exchange rate comes in. It answers a deeper question: After adjusting for the general price level in each country, how many Indian goods can you get for the price of one foreign good?
The Precise Meaning
The real exchange rate (RER) compares the purchasing power of two currencies within their own economies. It tells you the rate at which you can trade the goods and services of one country for those of another.
Real Exchange Rate=Pde×Pf
Where:
- e = Nominal exchange rate (units of domestic currency per unit of foreign currency — e.g., ₹83 per $1)
- Pf = Foreign price level (the general price of goods abroad, measured by a price index)
- Pd = Domestic price level (the general price of goods at home, measured by a price index)
Let's break this down with a concrete example.
Suppose India is the domestic country and the US is foreign. Let:
- e=83 (₹83 per $1)
- Pf=100 (a basket of US goods costs $100)
- Pd=100 (the same basket of Indian goods costs ₹100)
Then:
RER=10083×100=83 …
The foreign exchange rate is the price of one currency expressed in terms of another currency. It tells us how many units of the domestic currency must be given up to obtain one unit of a foreign currency, or equivalently, how many units of foreign currency can be purchased with one unit of domestic currency.
For instance, if the exchange rate between the Indian rupee and the US dollar is ₹75 per dollar, it means one US dollar costs ₹75, or one rupee buys 751 of a dollar. This rate is determined in the foreign exchange market through the interaction of demand for and supply of foreign currency. …
The foreign exchange rate is the price of one currency expressed in terms of another — it tells you how many units of your domestic currency you must give up to obtain one unit of a foreign currency, or vice versa.
The foreign exchange rate is fundamentally a price — but instead of pricing apples or steel, it prices money itself. When you travel abroad or when countries trade goods and services, they need a way to convert one currency into another. The exchange rate is the mechanism that makes this conversion possible.
Think of it this way: if you're an Indian importer buying machinery from the United States, the American seller wants payment in dollars, not rupees. You need to know how many rupees you must surrender to acquire each dollar. That ratio — rupees per dollar — is the exchange rate. It bridges two monetary systems and allows international transactions to happen.
More formally, the foreign exchange rate is the rate at which one country's currency can be exchanged for another country's currency. It can be quoted in two equivalent ways:
- Direct quotation (price quotation): the domestic currency price of one unit of foreign currency. For instance, ₹83 per US dollar means you pay ₹83 to get 1 US dollar.
- Indirect quotation (volume quotation): the foreign currency price of one unit of domestic currency. For example, 0.012 US dollars per rupee means one rupee buys you 0.012 US dollars.
Both convey the same information; they are reciprocals of each other. …

Statement 1 incorrectly defines the exchange rate as the bank rate. Statement 2 correctly describes the inverse relationship between the exchange rate and the quantity demanded of foreign exchange.
Let's break down each statement to understand the underlying economic concepts.
Understanding Statement 1: The price of a given currency in terms of another is known as bank rate.
The "price of a given currency in terms of another" refers to how much one currency is worth when exchanged for another. This fundamental concept in international economics is known as the exchange rate. For instance, if one US dollar can be exchanged for ₹83, then ₹83 is the exchange rate for one US dollar in Indian rupees. It tells us how many units of the domestic currency are needed to buy one unit of a foreign currency, or vice versa.
Exchange Rate: The price of one currency expressed in terms of another currency.
On the other hand, the bank rate is a monetary policy tool used by the central bank of a country (like the Reserve Bank of India). It is the interest rate at which the central bank lends money to commercial banks without demanding any collateral. It influences the overall interest rate structure in the economy and is distinct from the exchange rate.
Since the statement incorrectly equates the exchange rate with the bank rate, Statement 1 is false.
Understanding Statement 2: Demand curve for foreign exchange is a downward sloping curve.
The demand for foreign exchange arises from various international transactions. For example, when residents of a country want to:
- Import goods and services from abroad.
- Travel to foreign countries (tourism).
- Invest in foreign assets (e.g., buying foreign stocks or bonds).
- Send remittances to relatives living abroad.
All these activities require converting domestic currency into foreign currency, thus creating a demand for foreign exchange.
Now, let's consider the relationship between the exchange rate and the quantity demanded of foreign exchange. Suppose the exchange rate is expressed as the price of foreign currency in terms of domestic currency (e.g., rupees per US dollar).
- If the exchange rate falls (i.e., foreign currency becomes cheaper in terms of domestic currency), then:
- Imports become cheaper for domestic consumers, leading to an increase in import demand.
- Foreign travel becomes cheaper, encouraging more tourism abroad. …

The foreign exchange market is where currencies are bought and sold against each other, determining the exchange rate.
In the RBSE/CBSE Class-12 open-economy chapter, the foreign exchange market is the market in which one country's currency is exchanged for another's (for example, rupees for dollars). It brings together the demand for and supply of foreign currencies arising from international trade, investment and other transactions.

›Reveal solutionSolution
A currency needs STABLE purchasing power to be generally accepted internationally.
For a currency to function as an internationally accepted medium of exchange (or reserve currency), other countries, central banks, and traders must be confident that it will retain a broadly stable value over time — a currency with unstable (rapidly eroding or fluctuating) purchasing power would quickly lose the trust needed for others to hold or accept it in international dealings, since its real value could change sharply before it is used or converted. 'Only gold' and 'only barter' describe older or theoretical …

Foreign exchange = all foreign currencies (and claims on them) used for cross-border payments.
Foreign exchange refers to currencies of other countries (and near-money claims denominated in those currencies, such as foreign bank balances, bills of exchange and drafts) that a country's residents need in order to make payments to residents of other countries — for example, to pay for imports, to repay foreign loans, or to invest abroad. It is managed/held by a country's central bank (in India, the RBI) as foreign exchange reserves, and its market price in terms of the domestic currency is the exchange rate.

›Reveal solutionSolution
Interest rate differential is the gap between domestic and foreign interest rates; it drives capital inflows or outflows.
The interest rate differential is the difference between the rate of interest prevailing in the home country and the rate of interest abroad. If the domestic interest rate is higher than the foreign rate, the differential is positive and tends to attract foreign capital (inflows); if it is lower, capital flows out. This differential is therefore a key determinant of capital movements and of the excha …

- CBSE 2020Set 58/3/11 markQ.If the exchange rate of the home currency rises, the value of exports of the economy is likely to ________ . (Fill in the blank with correct answer)
›Reveal solutionSolution
When the home currency's exchange rate rises (appreciates), foreign buyers find domestic goods more expensive, leading to a likely decrease in the value of exports.
The question asks about the impact of a rising home currency exchange rate on the value of exports. To understand this, we first need to clarify what "exchange rate of the home currency rises" means and then trace its effects on international trade.
In economics, when the "exchange rate of the home currency rises," it means the home currency has appreciated. This implies that one unit of the home currency can now buy more units of foreign currency, or, conversely, one unit of foreign currency buys fewer units of the home currency. This change in relative value directly impacts the prices of goods traded internationally.
Let's break down the process:
-
Understanding "Exchange Rate of the Home Currency Rises"
- An exchange rate expresses the value of one currency in terms of another. For example, if the exchange rate is 1 USD=80 INR, it means 1 US Dollar can be exchanged for 80 Indian Rupees.
- When the "exchange rate of the home currency rises," it means the home currency appreciates. This implies that the home currency becomes stronger relative to foreign currencies.
- Consider India as the home country. If the exchange rate of the Indian Rupee (INR) rises, it means the INR can now buy more foreign currency. For instance, if the rate changes from 1 USD=80 INR to 1 USD=75 INR, this signifies an appreciation of the INR. Why? Because now you need fewer Rupees to buy one Dollar, meaning each Rupee is worth more Dollars than before (1 INR=1/80 USD initially, now 1 INR=1/75 USD).
-
Impact on the Price of Exports for Foreign Buyers
- Exports are goods and services produced domestically and sold to foreign countries. These goods are typically priced in the home currency by the domestic producers.
- When the home currency appreciates, foreign buyers need to spend more of their own currency to acquire the same amount of the home currency.
- Let's use our example: An Indian exporter sells a product for 8,000 INR.
- Initially, at 1 USD=80 INR, a US buyer would pay 8,000 INR/80 INR/USD=100 USD.
- After the INR appreciates to 1 USD=75 INR, the same product still costs 8,000 INR to the Indian producer. However, the US buyer now has to pay 8,000 INR/75 INR/USD≈106.67 USD.
- This shows that the price of Indian exports, when converted into foreign currency, has increased for foreign buyers. …
