1. Basics of Foreign Exchange Market (FOREX) (basic)

Foreign Exchange (FOREX) is the global network where one currency is traded for another. It isn't a single physical location like a stock exchange; rather, it is a 24-hour electronic market where commercial banks, brokers, and central banks interact across the world Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.91. In its simplest form, the exchange rate is the price of one currency in terms of another. For example, if 1 USD = ₹83, the 'price' of one dollar is 83 rupees. These rates essentially link national economies, allowing us to trade goods and services internationally India and the Contemporary World – II. History-Class X. NCERT(Revised ed 2025), The Making of a Global World, p.77.

The price of a currency is primarily determined by the market forces of demand and supply. This is known as a Flexible or Floating Exchange Rate system. If the global demand for Indian goods (like software or tea) increases, foreigners must buy Rupees to pay for them, which increases the demand for the Rupee and raises its value. Conversely, if Indians travel abroad more frequently, they 'supply' Rupees to the market to buy foreign currency, which can put downward pressure on the Rupee's value Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.92.

In India, our approach to foreign exchange has evolved significantly. Initially, because foreign currency was scarce, it was strictly regulated under FERA (1973). However, as our economy opened up after 1991, we moved toward a more liberalized management system under FEMA (1999). This shift reflected India's transition from 'controlling' a scarce commodity to 'managing' a vital tool of international trade Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking- Part I, p.67.

System Type	Mechanism	Government Role
Fixed Rate	Set by the government/central bank.	High intervention to maintain the peg.
Floating Rate	Determined by market demand and supply.	Minimal to no direct intervention.

2. Exchange Rate Systems: Fixed, Floating, and Managed (intermediate)

At its heart, an exchange rate is simply the price of one currency expressed in terms of another. It serves as the bridge that connects different national economies, allowing us to trade goods and services globally India and the Contemporary World – II, Chapter 3: The Making of a Global World, p.77. How this price is determined depends on the specific 'regime' or system a country chooses to follow. Historically, the world has oscillated between rigid control and market freedom.

There are three primary systems you must understand for the UPSC: Fixed, Floating, and Managed. In a Fixed Exchange Rate System, the government or central bank sets the currency's value against a major currency (like the US Dollar) or gold. While this provides great certainty for investors and helps control inflation, it requires the central bank to maintain massive foreign exchange reserves to defend that price whenever it's under pressure Indian Economy by Nitin Singhania, India’s Foreign Exchange and Foreign Trade, p.494. Conversely, in a Floating (or Flexible) Exchange Rate System, the price is left entirely to the market forces of demand and supply. If the world wants more Indian exports, the demand for Rupees goes up, and its value rises—without the government lifting a finger India and the Contemporary World – II, Chapter 3: The Making of a Global World, p.77.

Feature	Fixed Exchange Rate	Floating Exchange Rate
Determination	Set by Government/Central Bank	Market forces (Demand & Supply)
Forex Reserves	High requirement to maintain the 'peg'	Lower requirement; reserves not used for pricing
External Shocks	Economy is highly exposed to shocks	Acts as a cushion/insulation against shocks
Investment	High certainty encourages FDI	Volatility may discourage some investors

Today, most modern economies—including India—don't use a pure version of either. Instead, we use a Managed Floating System (often colloquially called 'Dirty Floating'). In this hybrid model, the exchange rate is generally determined by the market, but the Central Bank (like the RBI) intervenes to buy or sell foreign currency if the fluctuations become too volatile or 'disorderly' Macroeconomics NCERT Class XII, Open Economy Macroeconomics, p.95. This allows the country to enjoy the flexibility of the market while keeping a safety net to prevent sudden economic crashes Indian Economy by Nitin Singhania, India’s Foreign Exchange and Foreign Trade, p.493.

3. Balance of Payments (BoP): Current and Capital Accounts (intermediate)

Think of the Balance of Payments (BoP) as a country’s comprehensive financial diary. It records every single transaction between the residents of a country and the rest of the world over a year Nitin Singhania, Balance of Payments, p.487. The BoP is divided into two primary 'books': the Current Account and the Capital Account. To understand exchange rates, we must first understand how money flows through these accounts, as these flows create the supply and demand for a currency.
The Current Account tracks the 'here and now'—transactions involving goods, services, and income. It has two main parts: the Balance of Trade (export and import of physical goods) and Invisibles (services like software, tourism, and transfers like remittances) Macroeconomics (NCERT Class XII), Open Economy Macroeconomics, p.87. When a country exports more than it imports, it has a Current Account Surplus, meaning it is effectively a lender to the world. Conversely, a Current Account Deficit (CAD) means the nation is spending more foreign exchange than it is earning from trade, requiring it to borrow or attract investment to fill the gap.
This brings us to the Capital Account. This account deals with changes in the ownership of assets and liabilities. It doesn't track what we 'consume,' but rather how we 'fund' things or where we 'invest' Nitin Singhania, Balance of Payments, p.469. It includes Foreign Direct Investment (FDI), where a foreign company sets up a factory (Greenfield) or buys an existing one (Brownfield), and External Commercial Borrowings (ECB). While a Current Account deficit sounds negative, it is often balanced by a Capital Account surplus—meaning foreign investors are bringing money in, which keeps the overall BoP in balance Macroeconomics (NCERT Class XII), Open Economy Macroeconomics, p.89.

Feature	Current Account	Capital Account
Nature	Income and expenditure (Flow)	Assets and liabilities (Stock-impacting)
Components	Goods (Trade), Services, Remittances, Gifts	FDI, FPI, Loans (ECB), Banking Capital
Impact	Reflects a nation's competitiveness in trade	Reflects a nation's attractiveness for investment

4. Foreign Investment: FDI, FPI, and Capital Flows (intermediate)

In the realm of international finance, capital doesn't just sit still; it moves across borders seeking either safety or better returns. These movements, known as Capital Flows, are the lifeblood of the global economy and a primary driver of exchange rate volatility. We generally classify these flows into two main categories based on the investor's intent and the level of control they seek: Foreign Direct Investment (FDI) and Foreign Portfolio Investment (FPI). FDI is often called 'stable' or 'long-term' capital. It occurs when a foreign entity invests in the productive capacity of a country—think of a mobile company building a manufacturing plant or a tech giant setting up a massive data center. Because it involves physical assets and active management (like appointing a Board of Directors), it cannot be easily pulled out overnight Vivek Singh, Money and Banking- Part I, p.99. In contrast, FPI involves buying financial assets like stocks or bonds. These investors are usually looking for short-term capital gains or dividends and do not seek management control. In India, a thumb rule is often applied: if a foreign investor holds less than 10% of a listed company's shares, it is treated as FPI; 10% or more is classified as FDI Nitin Singhania, Balance of Payments, p.477.

Feature	Foreign Direct Investment (FDI)	Foreign Portfolio Investment (FPI)
Nature	Long-term and stable	Short-term and volatile
Market	Usually through the Primary Market (new capital)	Usually through the Secondary Market (ownership change)
Control	Active management & decision making	Passive investment; no management say
Target	Company's long-term profit	Changes in share prices/interest rates

A critical sub-concept here is Hot Money. This refers to FPI capital that moves rapidly between countries to chase higher short-term interest rates or quick profits Vivek Singh, Terminology, p.456. When global interest rates change, this 'hot money' can exit a country in a flash, causing a sudden spike in the supply of the local currency and a sharp depreciation of the exchange rate. This is why economists keep a much closer watch on FPI flows than FDI when predicting immediate currency movements.

5. RBI's Role and External Indicators (NEER/REER) (exam-level)

While the market determines the daily value of the Rupee, the Reserve Bank of India (RBI) acts as a watchful guardian to ensure stability. However, looking at just one exchange rate (like USD/INR) is like looking at one tree instead of the whole forest. To understand India's overall trade health, we use two critical indices: NEER and REER.

NEER (Nominal Effective Exchange Rate) is a weighted average of the Rupee against a basket of currencies of India's major trading partners. If the NEER increases, the Rupee is effectively appreciating against the basket. However, NEER doesn't account for inflation. This is where REER (Real Effective Exchange Rate) comes in. REER adjusts the NEER for inflation differentials between India and its partners Indian Economy, Vivek Singh (7th ed. 2023-24), Fundamentals of Macro Economy, p.27. It is the gold standard for measuring export competitiveness: an increasing REER suggests that Indian goods are becoming more expensive relative to foreign goods, potentially hurting exports Indian Economy, Vivek Singh (7th ed. 2023-24), Fundamentals of Macro Economy, p.26.

Indicator	What it measures	Key Focus
NEER	Weighted average of nominal exchange rates.	External value of currency.
REER	NEER adjusted for price level (inflation) differences.	Trade competitiveness.

When these indicators show excessive volatility, the RBI intervenes. A primary tool is Sterilization. If there is a massive surge in foreign capital (Dollars), the Rupee might appreciate too quickly, hurting exporters. To prevent this, the RBI buys those Dollars. However, paying for Dollars injects new Rupees into the system, which can cause inflation. To "mop up" this excess Rupee liquidity, the RBI then sells Government Securities (G-Secs) to the banks Indian Economy, Nitin Singhania (ed 2nd 2021-22), India’s Foreign Exchange and Foreign Trade, p.498. Another sophisticated tool is the Forex Swap, where the RBI exchanges Dollars for Rupees with banks for a fixed period to manage liquidity and exchange rate expectations simultaneously Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking- Part I, p.102.

6. Economic Determinants of Currency Price (exam-level)

Concept: Economic Determinants of Currency Price

7. Non-Economic Determinants: Political and Global Factors (exam-level)

While exchange rates are fundamentally driven by the laws of demand and supply, these market forces do not operate in a vacuum. Beyond trade balances and interest rates, the political and global environment of a nation acts as the bedrock of "trust" that determines the value of its currency. In a floating exchange rate system, where the government does not fix the price, the market constantly evaluates a country’s political health to decide if its currency is a safe place to store wealth NCERT Class X, The Making of a Global World, p.77.

Political stability is perhaps the most significant non-economic determinant. Capital is highly sensitive to risk; therefore, stable governments with predictable policy frameworks attract foreign investment. This influx of capital increases the demand for the domestic currency, causing it to appreciate. Conversely, political unrest, frequent changes in leadership, or civil instability often lead to capital flight, where investors sell off local assets, causing the currency to become a soft currency—one that is unstable, fluctuates erratically, and depreciates rapidly Indian Economy, Nitin Singhania, p.501.

On the global stage, the role of international institutions is often misunderstood. It is important to note that the World Bank does not decide currency prices; its primary focus is on long-term developmental lending. However, the International Monetary Fund (IMF) plays a role in signaling currency strength through its Special Drawing Rights (SDR) basket. For a currency to be included in this elite group, the country must be a major global exporter and its currency must be "freely usable." The continued dominance of the US Dollar as a global reserve currency is reinforced by political factors, such as the United States holding the maximum voting rights (17.46%) in the IMF Indian Economy, Nitin Singhania, p.515.

Factor	Hard Currency (e.g., USD, Yen)	Soft Currency (e.g., Bolivar)
Political Climate	High stability and rule of law.	High risk of instability or policy shifts.
Global Demand	Used as a "safe haven" store of value.	Low liquidity; avoided by international markets.
Reliability	Trusted for long-term trade and debt.	Frequent and unpredictable depreciation.

8. Solving the Original PYQ (exam-level)

This question brings together your understanding of the Floating Exchange Rate system and market forces. When you studied the Balance of Payments and International Trade, you learned that a currency's value is essentially its "price" relative to others, driven primarily by supply and demand in the forex market. This specific PYQ tests your ability to distinguish between direct market determinants—factors that cause immediate shifts in currency desirability—and institutional roles or abstract indicators that do not directly set prices.

To arrive at the correct answer, we must use the Elimination Method. Statement 1 is a classic "authority trap"; the World Bank is an international development institution, not a global regulator that fixes currency prices. Eliminating it immediately removes options (A) and (D). Moving to the core logic: if global demand for a country’s goods and services (Statement 2) increases, foreigners must buy that country's currency to pay for them, driving the price up. Similarly, political stability (Statement 3) acts as a magnet for foreign investment; a stable government reduces the risk of sudden policy shifts, making the currency a "safe haven." Statement 4, "Economic potential," is a distractor because while it influences long-term sentiment, it is not a direct trigger for daily market pricing compared to actual trade flows and stability.

Therefore, the most accurate factors are 2 and 3, leading us to (B) 2 and 3 only. As emphasized in India and the Contemporary World – II. History-Class X . NCERT(Revised ed 2025), the shift away from fixed rates meant that a currency’s value became subject to the volatile fluctuations of international demand and the perceived strength of the issuing nation. Always look for immediate market drivers over long-term structural concepts when the question asks how prices are "decided" in the market.
