Assertion (A) : Devaluation of a currency may promote export. Reason (R) : Price of the country’s products in the international market may fall due to devaluation.

1. Balance of Payments (BoP) Framework (basic)

To understand how a country interacts with the global economy, we look at its Balance of Payments (BoP). Think of the BoP as a comprehensive financial statement or a ledger that records every single economic transaction between the residents of a country (like India) and the rest of the world over a specific period, usually a year. It tells us whether a country is a 'net creditor' or a 'net debtor' to the world. Historically, the BoP is divided into two main 'buckets' or accounts: the Current Account and the Capital Account. The Current Account captures the flow of goods, services, and income. It is essentially about 'earned' or 'spent' money that does not create a future liability. In contrast, the Capital Account records transactions that lead to a change in the assets or liabilities of residents or the government Indian Economy, Vivek Singh (7th ed. 2023-24), Chapter 2, p.107. For instance, if you export tea, it's Current Account; if a foreign company buys a factory in India, it's Capital Account because it changes ownership of assets.

Feature	Current Account	Capital Account
Nature	Flow of goods, services, and transfers.	Change in stock of assets and liabilities.
Components	Trade in goods, services (invisibles), and gifts/remittances.	FDI, FII, external loans, and banking capital.
Impact	Reflects the 'Net Income' of a nation.	Reflects how the nation's 'Wealth' is being financed or invested.

When we look deeper into the Current Account, we find the Balance of Trade (BoT), which specifically refers to the export and import of physical goods (visibles) Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.87. However, a country might have a trade deficit (buying more goods than selling) but still have a healthy BoP if it earns enough from 'invisibles' like software services or remittances from citizens abroad. If the total receipts are less than total payments, the country faces a Current Account Deficit (CAD), which must then be financed by the Capital Account—either by attracting foreign investment or by dipping into foreign exchange reserves Geography of India, Majid Husain (9th ed.), Transport, Communications and Trade, p.52. Modern accounting standards (BPM6) have slightly refined this by introducing a Financial Account specifically for trade in financial assets like bonds and shares, though in many basic discussions, these are still grouped under the broader Capital Account umbrella Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.90.

2. Exchange Rate Systems: Fixed vs. Floating (basic)

At its heart, an exchange rate is simply the price of one currency expressed in terms of another. Just like the price of apples can change based on how many people want them, the 'price' of the Rupee changes. However, how this price is determined depends on the Exchange Rate System a country chooses to follow. There are two primary ends of the spectrum: the Flexible (Floating) system and the Fixed (Pegged) system Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.92.

In a Flexible Exchange Rate System, the value of the currency is determined purely by the market forces of demand and supply. If more foreigners want to buy Indian goods or invest in India, the demand for the Rupee rises, and its value goes up—this is called Appreciation. Conversely, if the Rupee's value falls due to market forces, it is called Depreciation Indian Economy, Nitin Singhania (ed 2nd 2021-22), India’s Foreign Exchange and Foreign Trade, p.494. In contrast, under a Fixed Exchange Rate System, the government or Central Bank sets a specific value for the currency against a base (like Gold or the US Dollar). If the government deliberately decides to lower this official value, it is called Devaluation; if they increase it, it is called Revaluation Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.95.

Why does this matter? A weaker currency (through either depreciation or devaluation) makes a country's exports cheaper for the rest of the world. For instance, if the Rupee moves from ₹70 to ₹80 per $, a foreign buyer can get more Indian goods for the same single dollar. This often leads to a rise in export volumes Indian Economy, Nitin Singhania (ed 2nd 2021-22), India’s Foreign Exchange and Foreign Trade, p.495. Most modern economies, including India, use a Managed Float, which is a hybrid system where the market determines the rate, but the Central Bank intervenes occasionally to prevent extreme volatility.

Feature	Floating (Flexible) System	Fixed (Pegged) System
Determination	Market forces (Demand & Supply)	Government/Central Bank decision
Term for 'Value Down'	Depreciation	Devaluation
Term for 'Value Up'	Appreciation	Revaluation

3. Foreign Exchange Reserves and RBI Intervention (intermediate)

When foreign capital flows into India—through investments or exports—it creates a high demand for the Indian Rupee, causing it to appreciate (get stronger). While this sounds positive, a too-strong Rupee makes Indian exports more expensive and less competitive globally. To prevent this rapid appreciation, the Reserve Bank of India (RBI) intervenes in the foreign exchange market by purchasing excess dollars. This action leads to the accumulation of Foreign Exchange Reserves, which are largely held as Foreign Currency Assets (FCA) and invested in safe avenues like US government bonds Vivek Singh, Money and Banking- Part I, p.76.

However, this intervention creates a secondary challenge: liquidity management. When the RBI buys dollars from banks, it pays for them by injecting fresh Indian Rupees into the economy. This surge in the money supply can lead to inflationary pressure. To neutralize this "side effect," the RBI uses a technique called Sterilization. In a typical sterilization operation, the RBI offsets the Rupee injection by selling Government Securities (G-Secs) through Open Market Operations (OMO) Vivek Singh, Money and Banking- Part I, p.64. This "mops up" the excess Rupees from the banking system, keeping the domestic money supply stable while still having achieved the goal of preventing the Rupee from becoming too expensive Nitin Singhania, India’s Foreign Exchange and Foreign Trade, p.498.

Step	Action by RBI	Goal/Effect
Intervention	Buys Dollars / Sells Rupees	Prevents Rupee appreciation; builds Forex reserves.
Sterilization	Sells G-Secs (Bonds)	Sucks out excess Rupee liquidity to prevent inflation.

Sometimes, the RBI uses more complex tools like Forex Swaps, where it buys dollars today and agrees to sell them back at a future date at a specific premium Vivek Singh, Money and Banking- Part I, p.102. These tools allow the RBI to act as a "shock absorber" for the economy, ensuring that sudden global capital shifts don't cause chaotic swings in the value of our currency or the prices in our markets.

4. NEER and REER: Measuring Competitiveness (intermediate)

When we look at the exchange rate, we usually focus on the Rupee vs. the US Dollar. However, India trades with dozens of countries—from the Eurozone to China and the UAE. To understand how the Rupee is performing against the world at large, we use the Nominal Effective Exchange Rate (NEER). Think of NEER as a "weighted average" of the Rupee's value against a basket of currencies of our major trading partners. If India trades more with China than with the UK, the Yuan gets a higher "weight" in this index Vivek Singh, Fundamentals of Macro Economy, p.27. An increase in NEER signifies that the Rupee is appreciating against the basket, making it stronger in nominal terms.

While NEER tells us about currency strength, it doesn't tell us the full story of trade competitiveness because it ignores price levels (inflation). This is where the Real Effective Exchange Rate (REER) comes in. REER is simply the NEER adjusted for the inflation differences between India and its trading partners Nitin Singhania, Chapter 17, p.496. For example, if the Rupee's value stays the same (stable NEER) but inflation in India is much higher than in the US, Indian goods (like a burger) will become more expensive and less attractive to foreign buyers Vivek Singh, Fundamentals of Macro Economy, p.25. Therefore, an increase in REER indicates a loss of trade competitiveness, as domestic goods are becoming relatively pricier than foreign goods.

Feature	NEER (Nominal)	REER (Real)
What it measures	Weighted average of exchange rates.	NEER adjusted for relative inflation.
Focus	External value of the currency.	International trade competitiveness.
Effect of Increase	Currency Appreciation.	Loss of competitiveness (exports become costlier).

A crucial takeaway for policy is the divergence between these two. If India’s domestic inflation is consistently higher than that of its trading partners, the REER will tend to rise faster than the NEER. This tells the government that even if the exchange rate looks stable, our exporters are actually struggling because their costs are rising faster than their competitors' Vivek Singh, Fundamentals of Macro Economy, p.35.

5. The J-Curve Effect and Marshall-Lerner Condition (exam-level)

When a country faces a persistent trade deficit, it may allow its currency to depreciate (under a floating rate) or choose to devalue it (under a fixed rate). The primary goal is to make exports cheaper for foreign buyers and imports more expensive for domestic consumers, thereby narrowing the trade gap. As we see in Indian history, the government devalued the rupee by 18-19% in July 1991 to tackle a severe Balance of Payments (BOP) crisis Indian Economy, Nitin Singhania, Chapter 17, p.495. However, devaluation is not a magic wand; its success depends on a specific rule known as the Marshall-Lerner Condition.

The Marshall-Lerner Condition states that for a currency devaluation to improve the trade balance, the sum of the price elasticities of demand for exports and imports must be greater than 1. In simpler terms, consumers (both domestic and foreign) must be sufficiently sensitive to price changes. If demand is "inelastic" (meaning people keep buying the same amount regardless of price, perhaps because the goods are essential like oil or life-saving drugs), then devaluation might actually make the trade deficit worse because the country ends up paying more for the same volume of imports Indian Economy, Nitin Singhania, Chapter 17, p.493.

Even if the Marshall-Lerner condition holds true in the long run, we often observe the J-Curve Effect in the short run. This phenomenon describes a situation where a country’s trade balance initially worsens immediately after a devaluation before it starts to improve. This happens because:

• Fixed Contracts: International trade involves pre-signed contracts. For a few months, the country must pay the new, higher prices for imports it already committed to buy.
• Consumer Lag: It takes time for foreign consumers to notice that our goods are cheaper and for domestic consumers to find local substitutes for expensive imports.

Graphically, the trade balance dips (like the hook of a 'J') and then rises steadily as volumes adjust, eventually leading to the intended surplus or equilibrium.

6. Mechanism of Devaluation on Trade Prices (exam-level)

To understand how devaluation affects an economy, we must first distinguish it from depreciation. While depreciation happens due to market forces in a flexible system, devaluation is a deliberate policy action taken by a government or central bank under a fixed exchange rate system to officially lower the value of the domestic currency Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.94. This is often a strategic tool used to correct an adverse Balance of Payments (BoP) crisis, as seen during India’s economic reforms in July 1991 Indian Economy, Nitin Singhania (ed 2nd 2021-22), India’s Foreign Exchange and Foreign Trade, p.495.

The core mechanism of devaluation works through relative price changes. When a currency is devalued, it takes more units of the domestic currency to buy one unit of foreign currency (e.g., changing from $1 = ₹70 to $1 = ₹80). This has two simultaneous effects:

• Exports become cheaper for foreigners: A foreign buyer can now purchase more Indian goods with the same amount of dollars. This increased price competitiveness typically boosts export volumes Indian Economy, Nitin Singhania (ed 2nd 2021-22), Balance of Payments, p.484.
• Imports become costlier for residents: Domestic consumers now need more rupees to buy the same foreign product, which discourages the consumption of imported goods and reduces the outflow of foreign exchange Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking- Part I, p.40.

The success of this move depends on elasticity—how sensitive foreign and domestic buyers are to these price changes. If the demand for a country’s exports is high and the domestic need for imports (like oil) can be reduced, devaluation effectively narrows the trade deficit.

Action	Mechanism	Intended Result
Devaluation	Official increase in exchange rate (Currency becomes cheaper)	Boosts Exports; Restricts Imports
Revaluation	Official decrease in exchange rate (Currency becomes costlier)	Curbs Inflation; Makes Imports cheaper

7. Solving the Original PYQ (exam-level)

This question perfectly synthesizes the concepts of Exchange Rate Dynamics and International Trade Competitiveness. As you have learned in Indian Economy, Nitin Singhania, devaluation is a deliberate downward adjustment of the value of a country's currency against another. The logic follows a clear chain: when the Rupee is devalued, a foreign buyer needs fewer Dollars to buy the same amount of Rupees. Consequently, while the price of the product remains the same in domestic terms, its relative price in the international market falls. This makes the country's goods cheaper and more attractive to global consumers, which is the foundational mechanism for boosting export volumes.

To arrive at the correct answer, (A) Both A and R are true, and R is the correct explanation of A, you must evaluate the causal link. The Reason (R) identifies the drop in international prices as the specific driver. Because the price falls, the demand (exports) is likely to rise, assuming the goods have some degree of price elasticity. As noted in Indian Economy, Vivek Singh, the term "may" in the Assertion (A) is a vital qualifier; it acknowledges that while devaluation provides a price advantage, the actual growth in exports also depends on global economic conditions and the quality of the goods being sold.

UPSC often sets traps using Option (B), where both statements are factually correct but lack a causal connection. However, in this case, the price drop mentioned in R is the direct cause of the export promotion mentioned in A. Another common pitfall is confusing Devaluation with Appreciation; if the Reason had suggested that the currency value increased, the price would rise, making the Assertion false. Always remember: devaluation makes exports cheaper and imports costlier. This fundamental rule ensures you can navigate these assertion-reasoning questions by identifying the mathematical relationship between currency value and market price.
