Exchange Rate Regimes — Theory
Fixed Exchange Rate: The government pegs the currency to another currency or gold (Bretton Woods system, 1944-1971). The central bank must buy/sell forex reserves to hold the peg. Advantage: stable trade conditions and anchored inflation expectations. Disadvantage: sacrifices monetary policy independence, needs large reserves, and invites speculative attacks. Floating Exchange Rate: Market demand and supply alone determine the rate with no central bank intervention. Advantage: automatic BoP adjustment, monetary policy independence, no reserve drain. Disadvantage: excessive volatility, speculation, and trade uncertainty. Managed Float (Dirty Float): The market sets the rate, but the central bank steps in to prevent wild swings. India follows this system since 1993. RBI buys or sells dollars in spot and forward markets. The Impossible Trinity (Mundell-Fleming Trilemma) states a country cannot simultaneously maintain a fixed exchange rate, free capital mobility, and independent monetary policy — it can pick only two. India chose independent monetary policy plus partial capital mobility, operating a managed float as a result. UPSC Prelims asks the trilemma trade-offs and India's regime choice.
India's Exchange Rate History
Post-Independence (1947-1971): India pegged the rupee to British Pound Sterling at Rs 4.76 per dollar under the Bretton Woods system. Devaluations occurred in 1949 (following sterling) and 1966 (36.5% — Rs 4.76 to Rs 7.50 under PM Lal Bahadur Shastri, triggered by fiscal deficit, the 1965 war, and drought). Basket Peg (1975-1991): After Bretton Woods collapsed in 1971, India pegged to a trade-weighted currency basket, reducing single-currency dependence. Dual Exchange Rate — LERMS (1992-93): A transitional 40:60 split between official rate (government use) and market rate (private use), bridging the fixed-to-floating shift. Unified Rate (1993-present): Market-determined with RBI intervention. Rupee trajectory: Rs 31.37/$ (1993) to Rs 44 (2000) to Rs 48 (2010) to Rs 74 (2020) to Rs 85 (2025). Long-term depreciation of 3-4% annually reflects India's higher inflation relative to trading partners (PPP adjustment). Notable episodes: 1997-98 Asian crisis (rupee held unlike Southeast Asian collapses), 2008 GFC (Rs 39 to Rs 52), 2013 Taper Tantrum (Rs 54 to Rs 68.85), 2022 Russia-Ukraine war (Rs 74 to Rs 83). SSC tests the 1966 devaluation percentage. UPSC asks about LERMS and the managed float.
RBI's Exchange Rate Management
RBI manages the exchange rate through five instruments. (1) Spot market intervention: RBI buys dollars to prevent excessive rupee appreciation (adds reserves, injects rupee liquidity) or sells dollars to arrest depreciation (depletes reserves, absorbs liquidity). In FY22-23, RBI sold over $100 billion defending the rupee. (2) Forward market: RBI enters contracts to buy/sell dollars at future dates, managing forward premiums and expectations. (3) NDF (Non-Deliverable Forward) market: RBI first intervened in the offshore NDF market (London, Singapore, Dubai) in 2019. In 2020, domestic banks were allowed to participate in the NDF market. (4) Swap arrangements: Dollar-rupee swap auctions for 3-year or 5-year periods. The landmark FCNR(B) swap in 2013 offered concessional rates to banks, attracted $34 billion, and stabilised the rupee during the Taper Tantrum. (5) Interest rate adjustments: Raising policy rates makes rupee assets more attractive to foreign investors, supporting the currency. RBI explicitly states it does not target a particular exchange rate level — it intervenes only to curb excessive volatility. Critics argue RBI leans against appreciation more than against depreciation, protecting export competitiveness. Banking exams ask about RBI's intervention tools and FCNR(B) swap mechanics.
Forex Reserves — Composition & Management
India's forex reserves (~$640 billion, managed by RBI) comprise four components. Foreign Currency Assets (FCAs) make up ~93%, invested in sovereign bonds, central bank deposits, BIS deposits, and high-quality corporate bonds. The portfolio is predominantly in US dollars (~60%), with diversification into euros, yen, and pounds. Gold accounts for ~8-9% by value (~854 tonnes as of March 2025). RBI has steadily increased holdings, buying 80+ tonnes in 2024 alone to hedge against dollar depreciation and geopolitical risk. SDRs (Special Drawing Rights) come from IMF allocations — India received $17.86 billion in August 2021 (the largest-ever IMF allocation). The Reserve Tranche Position represents India's quota contribution to the IMF. Reserves peaked at ~$705 billion in September 2021 before declining as RBI aggressively sold dollars during 2022-23 (Fed hikes, Russia-Ukraine war). Current reserves provide ~10 months of import cover (3-6 months is comfortable; the Guidotti-Greenspan rule requires reserves to cover short-term external debt). RBI's DEIO manages reserves with safety and liquidity prioritised over returns. The opportunity cost: reserves earn ~4-5% (US Treasury yield) while India borrows domestically at ~7% (G-Sec yield) — this spread is the insurance premium for external stability. Exams test reserve components, the Guidotti-Greenspan rule, and import cover months.
FEMA & Capital Account Convertibility
FEMA 1999 replaced FERA 1973 in a paradigm shift. FERA treated forex violations as criminal offences (arrest, imprisonment) and followed a restrictive philosophy — "everything prohibited unless permitted." FEMA treats violations as civil offences (monetary penalties, ED adjudication) and follows a facilitative philosophy — "everything permitted unless prohibited." FEMA covers current account transactions (Section 5), capital account transactions (Section 6), exports (Section 7), and authorised persons/money changers. The Enforcement Directorate investigates violations; ATFE hears appeals. India achieved current account convertibility in 1994 under IMF Article VIII, allowing free conversion for trade, remittances, travel, education, and medical treatment. The Liberalised Remittance Scheme (LRS) lets residents remit up to $250,000 per financial year for permitted transactions. TCS at 5-20% applies on LRS above Rs 7 lakh. Capital account convertibility remains partial. Tarapore Committee-I (1997) set preconditions: fiscal deficit below 3.5%, inflation 3-5%, NPAs below 5%, CRR reduction. Tarapore Committee-II (2006) revised the roadmap for fuller CAC in three phases. India has liberalised incrementally — FDI is mostly automatic route, FPI limits have risen, ECB norms eased, LRS expanded — but full CAC is not achieved due to concerns about speculative flows. SSC asks FERA vs FEMA differences. UPSC tests Tarapore Committee recommendations and CAC preconditions.
REER, NEER & Currency Competitiveness
NEER (Nominal Effective Exchange Rate) is the weighted average of a currency against a basket of trading partner currencies, not adjusted for inflation. A depreciating NEER makes exports nominally cheaper. REER (Real Effective Exchange Rate) adjusts NEER for relative inflation between India and partners — the true competitiveness measure. When REER exceeds 100 (base year), the currency is overvalued in real terms and exports lose competitiveness because domestic inflation erodes the nominal depreciation advantage. When REER falls below 100, exports gain competitiveness. RBI publishes two REER indices: a 6-currency basket (USD, EUR, GBP, JPY, CNY, HKD) and a 40-currency basket. India's 40-currency REER has stayed above 100 (range 100-108) in recent years, suggesting mild real overvaluation. This partly reflects India's 4-6% inflation versus developed partners' 1-3%. The Balassa-Samuelson effect explains that developing countries with rapid tradable-sector productivity growth tend to see structural REER appreciation as non-tradable wages rise. Key exchange rate drivers: interest rate differentials, inflation differentials, BoP position, capital flows (FDI/FPI), oil prices (85% imported crude), speculation, RBI intervention, and geopolitical risks. UPSC asks REER interpretation. Banking exams test NEER vs REER definitions.
Internationalisation of the Rupee
India actively pushes rupee internationalisation. RBI's framework for rupee trade settlement (July 2022) allows invoicing, payment, and settlement in INR through Special Rupee Vostro Accounts (SRVAs). The mechanism: a partner-country bank opens an SRVA with an Indian authorised dealer; the importer deposits rupees; the exporter receives rupees. Surplus rupees can be invested in Indian G-Secs or used for bilateral trade. Over 20 banks from Russia, Sri Lanka, and others have opened SRVAs. The scheme gained urgency after Western sanctions on Russia forced India-Russia crude oil trade to seek non-dollar settlement. Masala Bonds are rupee-denominated bonds issued offshore — exchange rate risk falls on the investor, not the issuer. IFC issued the first Masala Bond in 2014. HDFC, NTPC, NHAI, and IRFC followed. The Indian rupee is not yet in the SDR basket (currently USD 43.38%, EUR 29.31%, CNY 12.28%, JPY 7.59%, GBP 7.44%). Inclusion would require fuller CAC and deeper forex markets. India has bilateral currency swap arrangements: India-Japan ($75 billion — the world's largest bilateral swap), SAARC ($2 billion), and BRICS CRA ($100 billion, India's share $18 billion). The Asian Clearing Union settles regional trade in ACU dollars. Benefits of internationalisation: reduced exchange rate risk, lower transaction costs, de-dollarisation, and seigniorage gains. Challenges: capital account restrictions, shallow forex market compared to USD/EUR, and rupee's long-term depreciation trend. UPSC tests Masala Bonds and the SRVA mechanism.
Currency Derivatives & Hedging
Currency derivatives let businesses and investors hedge exchange rate risk. Four instruments operate in India. (1) Currency futures: Standardised exchange-traded contracts on NSE, BSE, MCX-SX. Pairs: USD-INR, EUR-INR, GBP-INR, JPY-INR. Contract size: $1,000 for USD-INR. Cash-settled in rupees, accessible to residents and FPIs. (2) Currency options: Right (not obligation) to buy/sell at a specified rate. Available exchange-traded on NSE/BSE and OTC through authorised dealer banks for larger exposures. (3) Forward contracts: OTC contracts between banks and corporates, customised by amount, date, and rate. The most commonly used hedging tool for exporters and importers. Cancellation and rebooking allowed with conditions. (4) Currency swaps: Exchange of principal and/or interest across currencies. Cross-currency swaps hedge long-term exposures like ECBs. 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 — preventing a cascade of defaults if the rupee depreciates sharply against unhedged dollar borrowings. Banking exams test forward contract mechanics and UFCE norms.
Exchange Rate & Monetary Policy Nexus
Exchange rate and monetary policy are tightly linked through the "impossible trinity." India chose independent monetary policy and a managed float, with partial capital mobility as the adjustment variable. When RBI raises the repo rate, rupee assets become more attractive, attracting FPI inflows and supporting the rupee — but growth may slow. When RBI cuts rates, capital flows out seeking higher returns abroad, weakening the rupee — but domestic growth gets a boost. This creates policy dilemmas during stagflation or capital flight episodes. Sterilisation is critical: when RBI buys dollars to prevent rupee appreciation from capital inflows, it injects rupee liquidity that could stoke inflation. RBI sterilises by selling G-Secs through OMOs to absorb the excess rupees. The fiscal cost is significant — RBI earns low returns on dollar reserves but pays higher interest on sterilisation securities. The Market Stabilisation Scheme (MSS), introduced in 2004, issues bonds specifically for sterilisation. The cost falls on the government, not RBI, separating monetary policy (LAF) from exchange rate management (MSS). Dollar index (DXY) correlation matters: when the US dollar strengthens globally, most EM currencies including the rupee weaken regardless of India's fundamentals. UPSC Mains tests the sterilisation mechanism and MSS rationale.
Major Exchange Rate Crises in India
India has faced six major exchange rate stress episodes. (1) 1966 Devaluation: 36.5% devaluation under PM Shastri/Indira Gandhi. Triggers: fiscal deficit, 1965 India-Pakistan war, drought, US aid cuts. Nationally traumatic, it created lasting political aversion to devaluation. (2) 1991 Crisis: Forex reserves fell to $1.2 billion (2 weeks of imports). Rupee devalued ~20% in two steps. India pledged 67 tonnes of gold. IMF loan of $2.2 billion with conditionality. This crisis catalysed LPG reforms. (3) 1997-98 Asian Financial Crisis: India escaped the worst — rupee depreciated from Rs 35 to Rs 43 while Thailand, Indonesia, and South Korea saw 40-80% currency collapses. India's capital controls and low short-term external debt provided insulation, vindicating cautious CAC policy. (4) 2008 GFC: Rupee fell from Rs 39 to Rs 52. FPI outflows hit $15 billion. RBI deployed reserves aggressively. GDP growth dropped to 3.1% (Q4 FY09) but rebounded to 8%+ by FY10. (5) 2013 Taper Tantrum: Fed Chair Bernanke signalled QE tapering, triggering EM capital flight. India was a "Fragile Five" member with 4.8% CAD. Rupee crashed from Rs 54 to Rs 68.85 (26%). RBI Governor Rajan responded with the FCNR(B) swap ($34 billion attracted), raised short-term rates, tightened gold imports, and issued NRI bonds. (6) 2022 Crisis: Russia-Ukraine war, aggressive Fed hikes (525 bps), oil at $130/barrel. Rupee fell from Rs 74 to Rs 83. RBI spent $100+ billion defending the rupee. Exams frequently ask about the Fragile Five, 1966 percentage, and Rajan's 2013 measures.
Cryptocurrency & CBDC — Digital Rupee
India has taken a regulatory rather than prohibitory approach to crypto. RBI initially banned banks from dealing with crypto entities (2018 circular), but the Supreme Court struck this down in 2020. The government imposed a 30% tax on crypto gains (no loss set-off) and 1% TDS on transactions above Rs 10,000/year (Budget 2022). Trading volumes dropped sharply. RBI launched the e-Rupee (CBDC) in two phases. Wholesale CBDC (e-W) started November 2022 for G-Sec settlement with 9 participating banks. Retail CBDC (e-R) started December 2022 for person-to-person and merchant transactions — 5 million+ users across 16 banks by 2025. It works offline for small transactions at zero transaction cost. CBDC is legal tender, unlike private cryptocurrencies. For exchange rate implications: if the e-Rupee gains international acceptance, it could accelerate rupee internationalisation. However, if foreign CBDCs (especially China's e-CNY) dominate global trade, dollar dominance could erode and alter exchange rate dynamics. RBI participates in mBridge (BIS project with China, UAE, Thailand central banks) for cross-border CBDC payments — potentially reducing SWIFT and dollar-based correspondent banking dependence. SSC asks CBDC launch dates. UPSC tests implications for monetary sovereignty.
Purchasing Power Parity & Exchange Rate Misalignment
Purchasing Power Parity (PPP) theory says exchange rates should adjust so identical goods cost the same across countries in a common currency. Absolute PPP: Exchange rate = Price level A / Price level B. Relative PPP: Change in exchange rate = Inflation differential between two countries. India's GDP at market rate (2024): $3.7 trillion (5th largest). India's GDP at PPP: $14.6 trillion (3rd largest, after USA and China). The PPP conversion factor is about Rs 22-23 per dollar (2024) versus a market rate of Rs 85. This gap means non-tradable goods (rent, services, haircuts) are far cheaper in India. The Big Mac Index (The Economist's informal PPP gauge) shows a Big Mac costs about Rs 200 ($2.35) in India versus $5.69 in the US — implying the rupee is 59% undervalued by Big Mac PPP. The Penn Effect explains that developing countries with lower per-capita income tend to have PPP-undervalued currencies. As incomes rise, the real exchange rate appreciates (Balassa-Samuelson effect). Policy implication: PPP comparisons suit living standards while market rate comparisons suit trade competitiveness and financial analysis. India's per-capita GDP at market rate ($2,700) puts it in lower-middle-income, but at PPP ($9,200) it approaches upper-middle-income. UPSC Prelims tests PPP vs market GDP rankings. Banking exams ask Big Mac Index basics.
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.
