Unit 5: Foreign Exchange Market

1. Introduction to the Foreign Exchange Market

The Foreign Exchange Market (Forex or FX market) is an over-the-counter (OTC) global marketplace that determines the exchange rate for currencies around the world. It is the mechanism through which the currency of one country is exchanged for the currency of another, facilitating international trade and financial investments.

Key Characteristics of the Forex Market

• High Liquidity: It is the largest and most liquid financial market in the world, with daily trading volumes exceeding trillions of dollars.
• Over-The-Counter (OTC) Market: Unlike stock markets, the Forex market does not have a central physical location or clearinghouse. Trades are conducted electronically over-the-counter through a global network of banks and financial institutions.
• 24-Hour Operation: The market operates 24 hours a day, five days a week, moving across major financial centers (Sydney, Tokyo, London, New York).
• High Volatility: Exchange rates fluctuate rapidly in response to geopolitical events, economic data, and changes in monetary policy.

Functions of the Foreign Exchange Market

1. Transfer Function: It facilitates the transfer of purchasing power between countries (e.g., converting Indian Rupees into US Dollars to pay for imports).
2. Credit Function: It provides short-term credit to finance international trade. Instruments like bills of exchange and letters of credit are widely used.
3. Hedging Function: It provides mechanisms for individuals and businesses to protect themselves against adverse movements in exchange rates (forward contracts, options, futures).

Major Participants

• Central Banks (e.g., RBI in India): Intervene in the market to stabilize the domestic currency and manage foreign exchange reserves.
• Commercial Banks: Act as market makers, executing trades for their clients and trading on their own accounts.
• Multinational Corporations (MNCs): Participate in the market to facilitate international trade, pay for imports, and repatriate profits.
• Forex Brokers: Act as intermediaries connecting buyers and sellers.
• Speculators and Arbitrageurs: Trade with the motive of making a profit from currency price fluctuations or price discrepancies across different markets.

2. Types of Exchange Rates

An exchange rate is the price of one country's currency in terms of another. Depending on how this price is determined, exchange rate systems are classified into various types.

By Determination Mechanism

1. Fixed (Pegged) Exchange Rate System:

   • The value of a country's currency is fixed or pegged to a major currency (like the US Dollar) or a basket of currencies by the country's Central Bank or government.
   • Mechanism: The Central Bank buys and sells its own currency in the open market to maintain the fixed rate.
   • Advantage: Provides certainty for international trade and investments.

2. Floating (Flexible) Exchange Rate System:

   • The exchange rate is determined entirely by market forces of demand and supply for the currency, without any government intervention.
   • Advantage: Automatically adjusts to economic shocks and balances of payments deficits/surpluses.

3. Managed Float Exchange Rate System (Dirty Float):

   • A hybrid system where the exchange rate is generally determined by market forces, but the Central Bank intervenes occasionally to prevent extreme volatility.
   • Indian Context: India follows a Managed Float system. The Reserve Bank of India (RBI) does not target a specific exchange rate but intervenes to curb excessive speculation and volatility in the Rupee's value.

By Measurement and Scope

1. Nominal Exchange Rate (NER): The current market price at which one currency can be exchanged for another (e.g., 1 USD = 83 INR).
2. Real Exchange Rate (RER): The nominal exchange rate adjusted for inflation differentials between two countries. It measures the true purchasing power of a currency.
   • Formula: RER = Nominal Exchange Rate × (Domestic Price Level / Foreign Price Level)
3. Nominal Effective Exchange Rate (NEER): An unadjusted weighted average value of a country's currency relative to a basket of major trading partners' currencies.
4. Real Effective Exchange Rate (REER): The NEER adjusted for inflation. It is a key indicator of a country’s international competitiveness. If a country's REER is increasing, its exports are becoming more expensive and less competitive.

3. Currency Convertibility

Currency convertibility refers to the freedom to convert the domestic currency into foreign currencies and vice versa for various transactions without government restrictions. It bridges the gap between the domestic and global economy.

Convertibility is categorized based on the Balance of Payments (BoP) accounts:

1. Current Account Convertibility

• Meaning: The freedom to convert domestic currency into foreign currency for transactions related to trade in goods and services, remittances, and interest/dividend payments.
• Indian Context: India achieved Full Current Account Convertibility in August 1994, accepting the obligations under Article VIII of the IMF. This means Indians can freely buy foreign exchange for importing goods, traveling abroad, education, and medical treatment.

2. Capital Account Convertibility (CAC)

• Meaning: The freedom to convert local currency into foreign currency for acquiring capital assets abroad (e.g., buying real estate, investing in foreign stocks) and vice versa.
• Indian Context: India has Partial Capital Account Convertibility. While foreign investors have relatively easy access to Indian markets (FDI and FPI), resident Indians face limits on how much they can invest abroad (e.g., the Liberalised Remittance Scheme (LRS) limits outflows to $250,000 per financial year per resident individual).
• Tarapore Committee: The RBI set up the S.S. Tarapore Committee (1997 and 2006) to lay out a roadmap for full CAC. The committee recommended macroeconomic preconditions (low inflation, low fiscal deficit, strong banking system) before moving to full convertibility.

Advantages of Full Convertibility

• Encourages foreign capital inflows (FDI and FPI).
• Integrates the domestic financial system with global markets.
• Lowers the cost of capital for domestic businesses.

Disadvantages of Full Convertibility

• Makes the economy highly vulnerable to global financial shocks.
• Risk of sudden capital flight during economic crises (as seen in the 1997 Asian Financial Crisis).
• High exchange rate volatility.

4. Devaluation and Depreciation

While both terms refer to a decline in the value of a domestic currency relative to foreign currencies, they occur under different exchange rate regimes and have different underlying causes.

Depreciation

• Definition: A fall in the value of a currency in a floating exchange rate system due to market forces (demand and supply).
• Cause: Economic factors such as high domestic inflation, current account deficits, lower interest rates, or political instability lead to higher demand for foreign currency and lower demand for domestic currency.
• Nature: It is a continuous, market-driven process occurring daily.
• Example: If the USD to INR rate moves from 1 USD = 80 INR to 1 USD = 83 INR purely due to market dynamics, the Rupee has depreciated.

Devaluation

• Definition: A deliberate, official downward adjustment of the value of a country's currency relative to another currency in a fixed exchange rate system.
• Cause: It is a policy decision made by a country's government or Central Bank, usually to correct a severe balance of payments deficit.
• Nature: It is an intentional, discrete, and sudden event.
• Example: Before adopting a market-determined system, the Indian government officially devalued the Rupee in 1949, 1966, and 1991 to boost exports and manage severe economic crises.

Key Differences: Devaluation vs. Depreciation

Economic Impact of Devaluation/Depreciation

Regardless of whether a currency is devalued or depreciates, the macroeconomic impacts are largely similar:

1. Boost to Exports: Domestic goods become cheaper for foreign buyers, potentially increasing export volumes.
2. Costlier Imports: Foreign goods become more expensive in domestic currency, which can help reduce a trade deficit but may harm import-dependent industries.
3. Imported Inflation: Increased costs of essential imports (like crude oil in India) lead to higher inflation in the domestic economy.
4. Increased Debt Burden: The cost of servicing foreign-denominated debt (loans taken in USD) increases significantly for domestic corporations and the government.
