Exchange Rate Regimes — Theory
Fixed Exchange Rate: Currency value pegged to another currency or gold (Bretton Woods system, 1944-1971). Government/central bank must maintain the peg by buying/selling forex reserves. Advantages: Stability for international trade, anchors inflation expectations. Disadvantages: Loss of monetary policy independence, requires large forex reserves, vulnerable to speculative attacks. Floating Exchange Rate: Determined entirely by market forces of demand and supply. No central bank intervention. Advantages: Automatic adjustment to BoP imbalances, monetary policy independence, no need for large reserves. Disadvantages: Excessive volatility, speculative attacks, uncertainty for trade. Managed Float (Dirty Float): Market-determined but central bank intervenes to prevent excessive volatility — India follows this system since 1993. RBI intervenes through buying/selling dollars in the spot and forward markets. The Impossible Trinity (Mundell-Fleming Trilemma): A country cannot simultaneously have: (1) Fixed exchange rate, (2) Free capital mobility, (3) Independent monetary policy. It can choose only two. India chose independent monetary policy + partial capital mobility — hence managed float (not fully fixed).
India's Exchange Rate History
Post-Independence (1947-1971): India adopted the Bretton Woods system — rupee pegged to British Pound Sterling at Rs 4.76 per dollar. Devaluations in 1949 (following sterling devaluation) and 1966 (36.5% — Rs 4.76 to Rs 7.50 per dollar under PM Lal Bahadur Shastri, driven by fiscal deficit, war with Pakistan 1965, and drought). Basket Peg (1975-1991): After Bretton Woods collapsed (1971), India pegged the rupee to a basket of currencies weighted by trade shares — reduced dependence on any single currency. Dual Exchange Rate — LERMS (1992-93): Transitional arrangement. 40% of forex earnings converted at official rate (government use), 60% at market rate (private use). This was the stepping stone from fixed to floating. Unified Rate (1993-present): Market-determined exchange rate with RBI intervention — the managed float regime. Rupee trajectory: Rs 31.37/$ (1993) → Rs 44/$ (2000) → Rs 48/$ (2010) → Rs 62/$ (2015) → Rs 74/$ (2020) → Rs 85/$ (2025). Long-term depreciation trend of about 3-4% annually reflects India's higher inflation relative to trading partners (purchasing power parity adjustment). Notable episodes: 1997-98 Asian Financial Crisis (rupee managed well — limited depreciation unlike Southeast Asian currencies), 2008 Global Financial Crisis (rupee fell from Rs 39 to Rs 52), 2013 Taper Tantrum (Rs 54 to Rs 68.85), 2022 Russia-Ukraine war (Rs 74 to Rs 83).
RBI's Exchange Rate Management
RBI manages the exchange rate through multiple instruments: (1) Spot market intervention: Buying dollars (to prevent excessive rupee appreciation — adds to reserves, increases rupee liquidity) or selling dollars (to arrest depreciation — depletes reserves, absorbs rupee liquidity). In FY22-23, RBI sold over $100 billion in the spot market to defend the rupee. (2) Forward market: RBI enters forward contracts to buy/sell dollars at future dates — affects forward premium/discount and manages expectations. Net forward outstanding position of RBI reported quarterly. (3) NDF (Non-Deliverable Forward) market: RBI intervened in the offshore NDF market (London, Singapore, Dubai) for the first time in 2019 — NDF is a significant source of speculative pressure on the rupee. In 2020, RBI allowed domestic banks to participate in NDF market to improve linkage. (4) Swap arrangements: Dollar-rupee swap auctions — RBI buys/sells dollars for specified periods (3-year, 5-year). FCNR(B) swap in 2013: RBI offered concessional swap rates to banks raising FCNR(B) deposits — attracted $34 billion and stabilised the rupee during Taper Tantrum. (5) Interest rate adjustments: Raising policy rates makes rupee assets more attractive to foreign investors, supporting the currency. RBI has explicitly stated it does not target a particular exchange rate level — it intervenes only to curb excessive volatility and maintain orderly conditions. However, critics argue RBI often leans against appreciation (to protect export competitiveness) more than against depreciation.
Forex Reserves — Composition & Management
India's foreign exchange reserves (managed by RBI) comprise: Foreign Currency Assets (FCAs) — ~93% of total, invested in sovereign bonds, deposits with central banks and the BIS, and high-quality corporate bonds. Predominantly in US dollars (~60%), with diversification into euros, yen, pounds, and other currencies. Gold — ~8-9% by value (~854 tonnes as of March 2025). RBI has been steadily increasing gold holdings — bought 80+ tonnes in 2024 alone. Gold serves as hedge against dollar depreciation and geopolitical risk. SDRs (Special Drawing Rights) — allocated by IMF. India received $17.86 billion in SDR allocation in August 2021 (largest-ever IMF allocation). Reserve Tranche Position — India's quota contribution to the IMF. India's reserves: ~$640 billion (early 2025) — peaked at ~$705 billion in September 2021 before declining due to RBI's aggressive dollar sales to defend the rupee during 2022-23 (Fed rate hikes, Russia-Ukraine war). Reserves provide ~10 months of import cover (comfortable level: 3-6 months, Guidotti-Greenspan rule: reserves should cover short-term external debt). Reserve management: RBI's Department of External Investments and Operations (DEIO) manages reserves. Investment guidelines prioritise safety and liquidity over returns. Reserves are invested in sovereign bonds of AAA-rated countries, BIS deposits, and gold. Opportunity cost of reserves: Reserves earn low returns (US Treasury yield ~4-5%) while India borrows domestically at higher rates (G-Sec yield ~7%) — this spread represents the cost of maintaining reserves.
FEMA & Capital Account Convertibility
FEMA 1999 (Foreign Exchange Management Act): Replaced FERA 1973. Key shift — from "conservation" (restrictive) to "management" (facilitative) of foreign exchange. FERA violations were criminal offences (arrest, imprisonment); FEMA violations are civil offences (monetary penalties, adjudication by ED). FEMA has 49 sections covering: current account transactions (Section 5), capital account transactions (Section 6), export of goods and services (Section 7), and authorised persons/money changers. Enforcement: Enforcement Directorate (ED) investigates FEMA violations. Appellate Tribunal for Foreign Exchange (ATFE) hears appeals. Current Account Convertibility: Freedom to convert domestic currency for current account transactions (trade, remittances, travel, education, medical treatment abroad) — India achieved this in 1994 under Article VIII of IMF. Liberalised Remittance Scheme (LRS): Resident individuals can remit up to $250,000 per financial year for any permitted current or capital account transaction — education, travel, medical, gifts, investment in equity/property abroad. TCS (Tax Collected at Source) at 5-20% on LRS remittances above Rs 7 lakh. Capital Account Convertibility: Freedom to convert for capital transactions (investment, borrowing) — India has partial capital account convertibility. Tarapore Committee-I (1997): Recommended full CAC with preconditions — fiscal deficit <3.5% of GDP, inflation 3-5%, NPA <5%, CRR reduction. Tarapore Committee-II (2006): Revised roadmap — recommended fuller CAC in three phases (2006-2011). India has progressively liberalised — FDI is mostly automatic route, FPI limits raised, ECB norms eased, LRS for individuals — but full CAC not achieved due to concerns about speculative capital flows and financial stability.
REER, NEER & Currency Competitiveness
Nominal Effective Exchange Rate (NEER): The weighted average of a country's currency against a basket of trading partners' currencies — not adjusted for inflation. Shows nominal changes in the exchange rate. If NEER depreciates, the country's goods become cheaper for trading partners (in nominal terms). Real Effective Exchange Rate (REER): NEER adjusted for relative inflation between India and its trading partners. REER is the key measure of competitiveness. If REER > 100 (base year), the currency is overvalued in real terms — India's exports become less competitive because even though the nominal rate may have depreciated, domestic inflation has eroded that advantage. If REER < 100, the currency is undervalued — exports more competitive. RBI publishes two REER indices: 6-currency basket (USD, EUR, GBP, JPY, CNY, HKD) and 40-currency basket (major trading partners). India's 40-currency REER has generally been above 100 (range 100-108) in recent years, suggesting mild overvaluation in real terms. This is partly because India's inflation (4-6%) has been higher than developed country partners (1-3%). Balassa-Samuelson effect: In developing countries with rapid productivity growth in tradable sectors, the REER tends to appreciate as non-tradable sector wages rise — this is structural and doesn't necessarily indicate loss of competitiveness. Factors affecting exchange rate: Interest rate differentials (higher Indian rates attract capital, support rupee), inflation differentials (higher inflation weakens currency), BoP position (CAD puts depreciation pressure), capital flows (FDI/FPI inflows support rupee), oil prices (rising crude weakens rupee — India imports 85% of crude), speculation, RBI intervention, and geopolitical risks.
Internationalisation of the Rupee
India has been taking steps towards rupee internationalisation — making the rupee acceptable for international transactions beyond India's borders. RBI's framework for rupee settlement of international trade (July 2022): Allows invoicing, payment, and settlement of exports and imports in INR through Special Rupee Vostro Accounts (SRVAs). Mechanism: A bank in the partner country opens a SRVA with an authorised dealer bank in India. Importer deposits rupees in this account, exporter receives rupees from it. Surplus rupees can be invested in Indian government securities or used for bilateral trade. Over 20 banks from Russia, Sri Lanka, and other countries opened SRVAs. This mechanism gained urgency after Western sanctions on Russia (2022) — India-Russia trade (especially crude oil imports) needed non-dollar settlement. Rupee-denominated bonds (Masala Bonds): Indian entities raise capital abroad in rupees. Exchange rate risk borne by the investor, not the issuer. Named "Masala" by IFC (like Dim Sum bonds for CNY, Samurai for JPY). HDFC (2014 — first Masala Bond), NTPC, NHAI, IRFC issued Masala Bonds. INR in SDR basket: Not yet included. SDR basket currently has USD (43.38%), EUR (29.31%), CNY (12.28%), JPY (7.59%), GBP (7.44%). India's inclusion would require fuller capital account convertibility and deeper forex markets. Bilateral currency swap arrangements: India-Japan ($75 billion — largest bilateral swap globally), SAARC framework ($2 billion), BRICS Contingent Reserve Arrangement ($100 billion, India's commitment: $18 billion). Asian Clearing Union (ACU): India settles trade with ACU members (Bangladesh, Iran, Myanmar, Nepal, Pakistan, Sri Lanka, Bhutan, Maldives) in ACU dollar — reduces dollar usage in regional trade. Benefits of internationalisation: Reduced exchange rate risk for Indian businesses, lower transaction costs, reduced dependence on US dollar (de-dollarisation), enhanced global standing of rupee, seigniorage benefits. Challenges: India's capital account restrictions limit rupee's appeal, shallow forex market compared to USD/EUR, rupee's long-term depreciation trend discourages foreigners from holding rupee assets.
Currency Derivatives & Hedging
Currency derivatives allow businesses and investors to hedge against exchange rate risk. Types available in India: (1) Currency futures: Standardised contracts traded on recognised exchanges (NSE, BSE, MCX-SX). USD-INR, EUR-INR, GBP-INR, JPY-INR pairs available. Contract size: $1,000 for USD-INR. Settlement: Cash-settled in rupees. Accessible to resident Indians and FPIs. (2) Currency options: Right (not obligation) to buy/sell a currency at a specified rate. Exchange-traded options available on NSE/BSE. OTC (Over-the-Counter) options available through authorised dealer banks for larger exposures. (3) Forward contracts: OTC contracts between banks and corporate clients. Customised in terms of amount, date, and rate. Most commonly used hedging instrument for exporters and importers. Cancellation and rebooking allowed with conditions. (4) Currency swaps: Exchange of principal and/or interest in different currencies. Cross-currency swaps used for long-term hedging (e.g., ECB borrowers converting dollar liability to rupee). RBI permits various swaps for hedging underlying exposures. RBI's hedging requirements: Infrastructure companies with ECBs must hedge 70% of foreign currency exposure (reduced from 100% in 2019). Banks must assess Unhedged Foreign Currency Exposure (UFCE) of borrowers and maintain additional provisioning and capital for large UFCE. This is to prevent systemic risk — if many companies have unhedged dollar borrowings and the rupee depreciates sharply, it could trigger a cascade of defaults.
Exchange Rate & Monetary Policy Nexus
The exchange rate and monetary policy are deeply interconnected through the "impossible trinity" — India chose independent monetary policy and a managed float, with partial capital mobility as the adjustment variable. Interest rate-exchange rate linkage: When RBI raises the repo rate, it makes rupee-denominated assets more attractive relative to foreign assets — attracts capital inflows (FPI into debt), supports the rupee, but may slow economic growth. When RBI cuts rates, capital flows out seeking higher returns abroad, weakening the rupee, but stimulating domestic growth. This creates a policy dilemma during situations like: (a) Inflation is high (needs rate hike) but growth is slowing (needs rate cut) — stagflation scenario. (b) Rupee is depreciating due to capital outflows (needs rate hike) but economy needs support (needs rate cut). Sterilisation: When RBI buys dollars in the forex market (to prevent rupee appreciation from capital inflows), it injects rupee liquidity into the banking system. This could be inflationary. RBI "sterilises" by selling government securities through open market operations (OMOs) — absorbing the rupee liquidity. The fiscal cost of sterilisation is significant — RBI earns low returns on dollar reserves but pays higher interest on securities sold for sterilisation. Market Stabilisation Scheme (MSS): Introduced in 2004 specifically for sterilisation — RBI issues MSS bonds and T-Bills to absorb excess liquidity from forex intervention. The cost is borne by the government (not RBI). This separates monetary policy operations (LAF) from exchange rate management (MSS). Dollar index (DXY) correlation: When the US dollar strengthens globally (DXY rises), most emerging market currencies including the rupee tend to weaken — this is independent of India's fundamentals and makes exchange rate management challenging.
Major Exchange Rate Crises in India
India has faced several episodes of severe exchange rate stress: (1) 1966 Devaluation: Rupee devalued by 36.5% under PM Lal Bahadur Shastri/Indira Gandhi. Triggers: fiscal deficit, 1965 India-Pakistan war, drought (1965-66), aid cut by USA. This was a traumatic national experience — devaluation was seen as a sign of economic weakness and dependence on foreign powers. Created lasting political aversion to devaluation. (2) 1991 Crisis: Balance of Payments crisis. Forex reserves fell to $1.2 billion (2 weeks of imports). Rupee devalued by ~20% in two steps (July 1 and 3). India pledged 67 tonnes of gold. IMF loan of $2.2 billion with conditionality. This crisis catalysed the LPG reforms. (3) 1997-98 Asian Financial Crisis: While India escaped the worst (unlike Thailand, Indonesia, South Korea which saw 40-80% currency collapses), the rupee depreciated from Rs 35 to Rs 43. India's capital controls and low short-term external debt provided insulation. This crisis vindicated India's cautious approach to capital account liberalisation. (4) 2008 Global Financial Crisis: Rupee fell from Rs 39 to Rs 52. FPI outflows of $15 billion. RBI used reserves aggressively. India recovered relatively quickly — GDP growth fell to 3.1% (Q4 FY09) but rebounded to 8%+ by FY10. (5) 2013 "Taper Tantrum": When US Fed Chair Ben Bernanke signalled tapering of QE (quantitative easing), capital fled emerging markets. India was among the "Fragile Five" (with Brazil, Indonesia, South Africa, Turkey) — high CAD (4.8% of GDP in FY13), dependence on short-term flows. Rupee fell from Rs 54 to Rs 68.85 (26%). RBI Governor Raghuram Rajan's measures: FCNR(B) swap scheme ($34 billion attracted), raised short-term interest rates, tightened gold imports, issued sovereign bonds to NRIs. (6) 2022 Crisis: Russia-Ukraine war, US Fed aggressive rate hikes (525 bps in 18 months), oil price spike to $130/barrel. Rupee fell from Rs 74 to Rs 83. RBI spent $100+ billion in reserves defending the rupee — reserves fell from $642 billion to $525 billion before recovering.
Cryptocurrency & CBDC — Digital Rupee
The rise of cryptocurrencies (Bitcoin, Ethereum) posed challenges for exchange rate management and monetary sovereignty. India's approach: RBI initially banned banks from dealing with crypto entities (2018 circular — struck down by Supreme Court in 2020). Government considered a crypto ban bill (2021) but instead imposed a regulatory framework: 30% tax on crypto gains (no set-off of losses), 1% TDS on crypto transactions above Rs 10,000 per year (Budget 2022). This did not ban crypto but significantly reduced trading volumes. Central Bank Digital Currency (CBDC) — Digital Rupee: RBI launched the e-Rupee pilot in two phases: Wholesale CBDC (e₹-W): Launched November 2022 for settlement of G-Sec transactions. Participants: 9 banks. Reduces settlement risk and improves efficiency. Retail CBDC (e₹-R): Launched December 2022 for person-to-person and person-to-merchant transactions. Participants: 5 million+ users, 16 banks (by 2025). Available on mobile apps of participating banks. Works offline for small-value transactions. Zero transaction cost — unlike UPI which now charges merchants for some transactions. CBDC is legal tender (like physical rupee) — this distinguishes it from private cryptocurrencies. Implications for exchange rate: If e₹ gains international acceptance, it could facilitate rupee internationalisation. However, if foreign CBDCs (especially China's e-CNY) gain traction in global trade, it could challenge the dollar's dominance and alter exchange rate dynamics. Cross-border CBDC projects: RBI participates in mBridge (BIS project with China, UAE, Thailand central banks) for cross-border CBDC payments — could reduce dependence on SWIFT and dollar-based correspondent banking.
Purchasing Power Parity & Exchange Rate Misalignment
Purchasing Power Parity (PPP): Theory that exchange rates should adjust so that identical goods cost the same across countries when expressed in a common currency. Absolute PPP: Exchange rate = Price level in country A / Price level in country B. Relative PPP: Change in exchange rate = Difference in inflation rates between two countries. India's PPP vs Market Exchange Rate: India's GDP at market exchange rate (2024): $3.7 trillion (5th largest). India's GDP at PPP: $14.6 trillion (3rd largest, after USA and China). PPP conversion factor for India: about Rs 22-23 per dollar (2024) — versus market rate of Rs 85. This means prices of non-tradable goods (rent, services, haircuts) are much cheaper in India than in the US. The gap reflects India's lower wage level for non-tradable services. Big Mac Index (The Economist): Informal PPP measure. In 2024, a Big Mac costs about Rs 200 ($2.35) in India vs $5.69 in the US — implying the rupee is 59% undervalued against the dollar by the Big Mac PPP measure. This is typical for developing countries with low service-sector wages. Penn Effect: Developing countries with lower per-capita income tend to have currencies that are undervalued relative to PPP — because non-tradable services are cheaper. As incomes rise, the real exchange rate tends to appreciate (Balassa-Samuelson effect). Implications for policy: PPP-based comparisons are more appropriate for comparing living standards across countries. Market exchange rate comparisons are more appropriate for trade competitiveness and financial market analysis. India's per-capita GDP at market rate ($2,700) puts it in the lower-middle-income category, but at PPP ($9,200) it is closer to the upper-middle-income threshold.
Relevant Exams
Exchange rates and forex reserves are high-priority topics. UPSC tests REER, capital account convertibility, and FEMA provisions. Banking exams ask about forex reserve components, managed float regime, and Masala Bonds. SSC exams test factual questions on FERA vs FEMA, devaluation history, and current forex reserve levels.
