The following timeline guides faculty through Week 5 — the opening session of Unit 2 — establishing the institutional and historical context for the exchange rate determination theories that follow in Weeks 6–8.

1. What Is an Exchange Rate?

1.1 Definition and Quotation Conventions

An exchange rate is the price of one currency expressed in terms of another currency. It is the most important single price in any open economy — it determines the cost of everything the country buys from abroad and the revenue from everything it sells to the world. For the international financial manager, the exchange rate is simultaneously an input price (what the firm pays for foreign goods, services, and capital), an output price (what the firm receives for exports), and a source of risk (because exchange rates fluctuate, and future rates are uncertain).

Exchange rates can be quoted in two conventions, and confusing them is a persistent source of error:

India, like most countries, uses the direct quotation convention — the exchange rate is expressed as INR per unit of foreign currency. The UK is a notable exception: sterling is quoted indirectly (USD per GBP). The US dollar is quoted indirectly against most currencies (EUR/USD, GBP/USD, AUD/USD) — this is the "American convention" — but directly against a few (USD/JPY, USD/CAD). In this course, we will consistently use the direct quotation convention (INR per USD, INR per EUR, etc.) unless otherwise specified.

1.2 Nominal, Real, and Effective Exchange Rates

The simple bilateral exchange rate (INR/USD) is not the only relevant measure. Financial managers and policymakers use three distinct exchange rate concepts:

• Nominal Exchange Rate (E): The quoted market rate — INR 83 per USD. This is the rate reported in the news and used to settle individual transactions. For the financial manager, the nominal rate determines the INR value of each specific foreign-currency cash flow.
• Real Exchange Rate (RER): The nominal rate adjusted for relative price levels: RER = E × (P* / P), where E is the nominal rate (direct quote), P* is the foreign price level, and P is the domestic price level. The RER measures a country's international competitiveness — it tells you how expensive domestic goods are relative to foreign goods after adjusting for the exchange rate. If India's inflation is 6% and US inflation is 2%, but the INR/USD nominal rate remains unchanged at 83, the real exchange rate has appreciated by approximately 4% — Indian goods have become 4% more expensive relative to US goods, eroding India's export competitiveness. For the financial manager, changes in the real exchange rate signal shifts in the firm's long-term competitive position — this is economic exposure (introduced in Week 1).
• Nominal Effective Exchange Rate (NEER) and Real Effective Exchange Rate (REER): Bilateral rates (INR/USD) miss the fact that India trades with many countries, not just the US. The NEER is a trade-weighted average of the rupee's nominal exchange rates against a basket of trading-partner currencies. The REER is the NEER adjusted for relative inflation differentials. The RBI publishes 6-currency and 40-currency NEER and REER indices (base year: 2015–16 = 100). A REER above 100 indicates the rupee is overvalued relative to its base-year level; below 100 indicates undervaluation.

1.3 Three Functions of the Exchange Rate

The exchange rate serves three distinct functions in the international financial system, and the choice of exchange rate regime determines which function is prioritised:

1. As a Price — The Allocative Function: The exchange rate is the relative price of tradable goods versus non-tradable goods. A depreciation makes tradable goods (exports and import-competing goods) more profitable relative to non-tradables (local services, construction, retail). Resources — labour, capital, entrepreneurial talent — shift toward the tradable sector. The exchange rate thus shapes the structure of the economy. A systematically undervalued exchange rate (as China maintained for much of the 2000s) subsidises the export sector at the expense of domestic consumers of tradable goods. A systematically overvalued rate does the opposite — it subsidises consumption of imports and penalises export-oriented production.
2. As a Transmission Mechanism — The Macroeconomic Function: Exchange rate changes transmit external shocks to the domestic economy. A global commodity price spike (e.g., crude oil) is transmitted to the Indian economy through the exchange rate: the INR depreciates as the import bill surges, which further increases the INR price of oil (a double blow — the USD price has risen, and each USD now costs more INR). The exchange rate regime determines how much of the external shock is absorbed by the exchange rate (depreciation) versus domestic economic activity (recession via import compression). Under a fixed rate, the shock is absorbed by falling output and employment. Under a floating rate, it is absorbed by depreciation. There is no escape from the shock — the regime only determines how it is distributed between price adjustment and quantity adjustment.
3. As a Policy Variable — The Strategic Function: Governments can use the exchange rate as an instrument of economic policy. A competitive (undervalued) exchange rate can promote export-led growth. A strong (overvalued) rate can suppress inflation. Exchange rate policy interacts with monetary policy, fiscal policy, and trade policy — the Impossible Trinity (introduced in Week 4) captures the fundamental constraint: you cannot simultaneously control the exchange rate, control domestic interest rates, and leave capital free to move across borders. The regime choice determines which of these three policy goals you sacrifice.

2. Evolution of the International Monetary System

The contemporary landscape of exchange rate regimes is the product of a century and a half of institutional evolution — of systems designed, operated, strained, and ultimately abandoned. Understanding this history is not an antiquarian exercise. The features of each historical system — its mechanism of adjustment, its source of instability, its distribution of burdens between surplus and deficit countries — recur in contemporary policy debates. The Triffin Dilemma that doomed Bretton Woods reappears in discussions of the dollar's role as the dominant reserve currency. The adjustment asymmetry between surplus and deficit countries that plagued the Gold Standard is reproduced in the eurozone's internal imbalances today.

2.1 The Classical Gold Standard (1870s–1914)

Defining Features: Under the classical Gold Standard, each participating country defined its currency in terms of a fixed weight of gold and stood ready to convert its currency into gold (and gold into its currency) at that fixed price without limit. The exchange rate between any two currencies was determined by the ratio of their gold contents — the mint parity. For example, if £1 was defined as 113 grains of fine gold and USD 1 as 23.22 grains, the mint parity was £1 = USD 4.8665. Exchange rates could deviate from mint parity only within very narrow bounds — the gold points — determined by the cost of shipping and insuring gold between the two countries. Beyond those bounds, it became profitable to arbitrage the difference by physically shipping gold, which brought the exchange rate back within the gold points.

The Adjustment Mechanism — Hume's Price-Specie-Flow: David Hume's price-specie-flow mechanism (1752) described how BOP disequilibrium was self-correcting under the Gold Standard. A country with a trade deficit experienced a gold outflow. The reduction in the domestic money supply (which was directly linked to the gold stock) caused domestic prices to fall. Falling prices made exports cheaper and imports more expensive, which reversed the trade deficit. The surplus country experienced the opposite: gold inflow → increased money supply → rising prices → reduced exports, increased imports → surplus eliminated. The mechanism was automatic (it required no government or central bank action), symmetric (both surplus and deficit countries adjusted), but painful (adjustment occurred through domestic deflation in deficit countries and inflation in surplus countries).

Why the Gold Standard Worked — and Why It Failed: The Gold Standard functioned because of a unique confluence of conditions: (a) capital mobility was limited, so gold flows were the primary mechanism of BOP adjustment; (b) governments accepted the primacy of external stability over domestic objectives — they were willing to tolerate deflation and unemployment to maintain the gold parity; (c) the system had a credible anchor — the Bank of England, which managed the system de facto; and (d) labour markets were relatively flexible (weak unions, limited wage rigidity), so prices could fall without causing prolonged unemployment. World War I destroyed these conditions. Governments financed war expenditure by printing money (breaking the link to gold), imposed capital controls, and after the war, faced political demands — expanded suffrage, rising labour movements — that made domestic deflation politically unacceptable. The attempt to restore the Gold Standard in the 1920s (at pre-war parities that no longer reflected economic realities — most famously, Britain's return to gold in 1925 at the pre-war parity of £1 = USD 4.86, which Keynes called "the mistake of 1925") produced prolonged deflation and unemployment in countries that returned to gold at overvalued rates. The system disintegrated in the Great Depression, as countries abandoned gold to pursue domestic reflation — the "beggar-thy-neighbour" competitive devaluations of the 1930s.

2.2 The Interwar Period (1919–1939): Chaos and Competitive Devaluation

The interwar period is a cautionary tale of what happens without a functioning international monetary system. Countries devalued competitively to boost exports at each other's expense — a negative-sum game that reduced trade, fuelled protectionism (the US Smoot-Hawley Tariff of 1930), and deepened the Great Depression. The architects of the post-World War II system — Harry Dexter White (US) and John Maynard Keynes (UK) — were determined not to repeat this experience. The Bretton Woods system was designed explicitly to combine the stability of fixed exchange rates (to facilitate trade) with the policy flexibility that the Gold Standard had denied (to allow governments to pursue full employment).

2.3 The Bretton Woods System (1944–1971)

The Architecture: At the Bretton Woods Conference in New Hampshire (July 1944), 44 Allied nations agreed on a new international monetary order:

• The Dollar-Gold Peg: The US dollar was pegged to gold at USD 35 per ounce. The US stood ready to convert dollars held by foreign central banks into gold at that price.
• Pegged-but-Adjustable Rates: Other countries pegged their currencies to the US dollar (and therefore indirectly to gold) within a band of ±1% around the declared parity. Countries could change their parity ("devalue" or "revalue") in the event of a "fundamental disequilibrium" in their BOP — but only with IMF approval. This was the "adjustable peg."
• Capital Controls Permitted: Unlike the Gold Standard (where capital moved relatively freely in peacetime), Bretton Woods explicitly permitted (indeed encouraged) capital controls. The objective was to prevent speculative capital flows from forcing exchange rate changes and to give countries the policy autonomy to pursue domestic full employment without interest rates being dictated by the need to defend the exchange rate. Keynes's vision was of a system where "speculators" were kept in check so that trade — not financial flows — would determine exchange rates.
• The IMF as Lender of Last Resort: The International Monetary Fund was created to provide temporary financing to countries facing BOP difficulties, allowing them to adjust without resorting to deflationary policies or competitive devaluation.

The System in Practice — The Triffin Dilemma: The Bretton Woods system contained an internal contradiction identified by the Belgian-American economist Robert Triffin in 1960. For the world economy to grow, the supply of international reserves (primarily US dollars) had to grow. But dollars entered the international system through US BOP deficits — the US had to run persistent deficits, spending more abroad (through imports, foreign aid, military expenditure, and outward FDI) than it earned, so that the rest of the world could accumulate dollar reserves. Over time, as foreign dollar holdings grew relative to the US gold stock, confidence in the dollar's convertibility into gold at USD 35 per ounce eroded. "If all foreign central banks simultaneously demanded gold for their dollars, the US could not honour the commitment." This was the Triffin Dilemma: the system required US deficits to supply the world with reserves, but persistent US deficits undermined confidence in the dollar's gold backing. The system was inherently unstable.

Throughout the 1960s, the US ran increasingly large BOP deficits — driven by the Vietnam War, the Great Society domestic programmes, and the erosion of US trade competitiveness as Europe and Japan rebuilt. Foreign central banks (particularly France, under de Gaulle's directive) began converting their dollar holdings into gold. The US gold stock fell from over 20,000 tonnes in the late 1940s to approximately 8,000 tonnes by 1971. On 15 August 1971, President Richard Nixon "closed the gold window" — the US would no longer convert dollars into gold for foreign central banks. The core of the Bretton Woods system was severed. Nixon imposed a 10% import surcharge and a 90-day wage-price freeze. The dollar was devalued — the gold price was raised to USD 38 per ounce in December 1971 (the Smithsonian Agreement) and then to USD 42.22 per ounce in February 1973. But these were stopgap measures. By March 1973, the major currencies were floating against each other. The Bretton Woods system was dead.

Why Bretton Woods Matters for IFM Today: The collapse of Bretton Woods created the environment in which modern IFM operates. Before 1971, exchange rates were fixed (or adjusted only occasionally and with IMF approval). Currency risk, while not absent (devaluations did occur), was an episodic rather than a continuous concern. After 1973, exchange rates became volatile — they moved daily, sometimes dramatically, driven by capital flows that dwarfed trade flows. The entire apparatus of modern foreign exchange risk management — forwards, futures, options, swaps — was developed in response to the post-Bretton Woods world of floating (or managed-floating) rates. IFM as a distinct discipline did not exist before 1971 in anything like its modern form precisely because the financial management problems created by floating exchange rates did not exist.

3. The Spectrum of Exchange Rate Regimes

The post-Bretton Woods world did not converge on a single exchange rate regime. Instead, countries chose from a menu of regimes spanning a continuum from the most rigidly fixed to the most freely floating — and many countries' de facto regime (what they actually do) differs from their de jure regime (what they officially declare). The regime choice is one of the most consequential economic policy decisions a country makes, because it determines how the economy adjusts to external shocks, how much monetary policy autonomy the central bank retains, and what currency risks the private sector must manage.

3.1 Hard Pegs

Dollarisation / Euroisation: The most extreme form of a fixed exchange rate — a country abandons its national currency entirely and adopts a foreign currency (typically the US dollar or the euro) as its sole legal tender. The country's central bank ceases to exist as a monetary authority; there is no domestic monetary policy. The exchange rate is irrevocably fixed — because there is no domestic currency to fluctuate. Examples: Ecuador (dollarised in 2000 after a banking and currency crisis), El Salvador (dollarised in 2001), Panama (has used the US dollar alongside the Panamanian balboa since 1904), Montenegro and Kosovo (use the euro unilaterally — without being EU members or having ECB approval).

Advantages: Complete elimination of currency risk (encouraging trade and investment with the anchor-currency area); imported monetary credibility (the country "borrows" the anchor country's central bank credibility, eliminating the inflationary bias of a poorly managed domestic central bank); no speculative attacks on the domestic currency (because there is no domestic currency to attack).

Disadvantages: Complete loss of monetary policy autonomy (domestic interest rates are determined by the anchor country's central bank — the Federal Reserve or the ECB — regardless of domestic economic conditions); loss of seigniorage (the profit a government earns from issuing currency — the anchor country earns it instead); no lender-of-last-resort function in domestic currency (the central bank cannot print money to bail out domestic banks — it must hold sufficient reserves of the foreign currency to act as lender of last resort, which is costly and limited).

Currency Board: A slightly less extreme form of hard peg. The domestic currency exists, but it is backed 100% (or more) by reserves of the anchor foreign currency. The central bank commits to exchange domestic currency for the anchor currency at a fixed rate, on demand, without limit. The domestic monetary base (currency in circulation plus bank reserves) cannot exceed the central bank's foreign exchange reserves — the central bank cannot "print money" beyond what is backed by reserves. Examples: Hong Kong (HKD pegged to USD at 7.75–7.85 since 1983), Bulgaria (BGN pegged to EUR via a currency board since 1997), and historically, Argentina (1991–2001, pegged to USD at 1:1 — its catastrophic collapse is a cautionary tale).

The currency board is the institutional embodiment of the Impossible Trinity: the country chooses fixed exchange rate + free capital mobility, and sacrifices monetary policy autonomy completely. Hong Kong's interest rates are, in effect, set by the Federal Reserve — if the Fed raises rates, Hong Kong must follow (or risk capital outflows that would drain reserves and break the peg).

3.2 Soft Pegs

Conventional Fixed Peg: The country pegs its currency to a single foreign currency or a basket of currencies within a narrow band (±1%). Unlike a currency board, the peg is not backed by a 100% reserve requirement, and the central bank retains some (limited) monetary policy discretion. The peg is maintained through foreign exchange intervention — the central bank buys and sells the anchor currency to keep the market rate within the band — and, when necessary, through interest rate adjustments. The peg is "soft" because it can be changed — devalued or revalued — if economic fundamentals demand it (though such changes are politically costly and often delayed until a crisis forces them). Examples: Saudi Arabia (SAR pegged to USD at 3.75 since 1986), Nepal (NPR pegged to INR at 1.6 — reflecting the deep economic integration between the two economies).

Crawling Peg: The exchange rate is adjusted periodically (daily, weekly, or monthly) in small, pre-announced increments according to a formula — typically linked to the inflation differential between the home country and the anchor currency. The "crawl" is designed to prevent the real exchange rate from appreciating (which would erode competitiveness) while maintaining the predictability of a peg. A variant is the "crawling band" — the rate is allowed to fluctuate within a band, and the band itself crawls according to a formula. China maintained a crawling peg against the USD from 1994 to 2005. Several Latin American countries used crawling pegs in the 1980s–1990s as part of inflation-stabilisation programmes.

3.3 Intermediate Regimes

Managed Float (Dirty Float): The exchange rate is officially "floating" — determined by market forces — but the central bank intervenes actively (and often) to influence its level and/or reduce its volatility. Unlike a peg, there is no publicly announced target rate or band. The central bank's intervention is discretionary and its objectives may be multiple: smoothing excessive short-term volatility (acting as a "market maker of last resort"), preventing the rate from "overshooting" its equilibrium level, maintaining export competitiveness, or accumulating reserves as an insurance buffer. This is the regime India operates de facto and is the most common regime among emerging economies. We examine India's managed float in detail in Section 5.

Target Zone: The exchange rate is allowed to fluctuate within a publicly announced band around a central parity. The central bank intervenes only when the rate approaches the edges of the band. Within the band, market forces determine the rate. The European Monetary System (EMS) Exchange Rate Mechanism (ERM) — the precursor to the euro — was a target zone arrangement. The band width can be narrow (as in the original ERM, ±2.25%) or wide. A wide band (e.g., ±15%) gives the central bank substantial room to tolerate exchange rate movements without intervention while retaining the option to intervene if the rate moves too far from the central parity.

3.4 Free Float

Free (Independent) Float: The exchange rate is determined entirely by market forces — supply and demand in the foreign exchange market — without central bank intervention. The central bank does not target any particular exchange rate level or path. Monetary policy is directed entirely at domestic objectives (inflation, growth, employment). The exchange rate is a residual — it adjusts to whatever level equilibrates the foreign exchange market given the interest rate the central bank has set to achieve its domestic objectives. Examples: the United States, the Eurozone (euro floats against non-euro currencies), Japan, the United Kingdom, Australia, Canada. Note: even "free-floating" central banks occasionally intervene — the Bank of Japan has intervened periodically to weaken the yen; the ECB has intervened rarely but retains the capacity. A truly pure float with zero intervention is rare.

3.5 The "Fear of Floating" and the Persistence of Intermediate Regimes

In an influential 2002 paper, Guillermo Calvo and Carmen Reinhart documented a phenomenon they termed "fear of floating." Many countries that officially declare their exchange rate to be floating (de jure floaters) actually intervene heavily to stabilise the rate (de facto peggers or managed floaters). Why? Because for emerging economies, a free float is more costly than for developed economies:

• Liability Dollarisation: In emerging economies, a significant share of government debt, corporate debt, and household debt is denominated in foreign currency (primarily USD). A sharp depreciation increases the domestic-currency value of these debts, potentially causing widespread insolvencies — a "balance-sheet" channel of exchange rate transmission that is mostly absent in developed economies (which borrow primarily in their own currency). This is "original sin" in international finance — the inability of emerging economies to borrow abroad in their own currency.
• Exchange Rate Pass-Through to Inflation: In emerging economies, exchange rate changes pass through to domestic prices more quickly and more completely than in developed economies. A 10% depreciation might add 2–4 percentage points to inflation in an emerging economy versus 0.5–1 percentage points in a developed economy. Central banks with inflation targets cannot be indifferent to large exchange rate movements.
• Thin and Volatile FX Markets: Emerging-economy FX markets are less deep and less liquid than those of major currencies. A relatively small order flow can move the exchange rate significantly, creating excessive volatility unrelated to fundamentals. The central bank intervenes to act as a stabilising market maker.

The "fear of floating" explains why intermediate regimes — particularly managed floats — have persisted despite predictions (the "hollowing-out hypothesis" of the 1990s) that countries would converge toward corner solutions (hard pegs or free floats) and abandon intermediate regimes as unsustainable. Intermediate regimes have proved remarkably durable because they offer emerging economies a pragmatic middle ground — the benefits of some exchange rate flexibility (partial shock absorption) without the full costs of a free float (excessive volatility, loss of competitiveness, balance-sheet stress).

4. IMF Classification of Exchange Rate Arrangements

The IMF's Annual Report on Exchange Arrangements and Exchange Restrictions (AREAER) classifies member countries' exchange rate regimes using a detailed taxonomy. Critically, the IMF distinguishes between a country's de jure classification (what the country officially declares its regime to be) and its de facto classification (what the country's observed behaviour — the volatility of its exchange rate, the frequency and scale of its FX intervention — reveals its regime to actually be). The de facto classification frequently differs from the de jure, and it is the de facto regime that matters for economic outcomes and for IFM.

Why De Jure and De Facto Diverge: Countries have incentives to misrepresent their regime. A country that claims to float but actually pegs ("fear of floating") may do so to signal commitment to market-oriented policies (pleasing the IMF, rating agencies, and foreign investors) while quietly intervening to stabilise the rate (pleasing domestic exporters and borrowers with foreign-currency debt). Conversely, a country that claims to peg but frequently adjusts the peg may be trying to import the credibility of a fixed regime while retaining the flexibility to devalue when domestic political pressure demands it. The IMF's de facto classification uses statistical analysis of exchange rate volatility, reserve changes, and interest rate behaviour to infer the true regime.

The IMF's De Facto Classification (10 Categories, Condensed):

The IMF classifies India's de facto regime as "Floating" (Category 8) — a market-determined rate with RBI intervention limited to smoothing excessive volatility rather than targeting a specific rate level. Some external analysts argue India's extensive reserve accumulation (buying USD to prevent rupee appreciation) pushes the de facto regime closer to a "Stabilised arrangement" (Category 4) or a "Crawl-like arrangement" (Category 6). The debate illustrates the inherently ambiguous nature of managed floats — the line between "smoothing volatility" and "targeting a level" is blurry and subjective.

5. India's Exchange Rate Regime — From LERMS to the Present

5.1 The Pre-1991 Regime: Fixed but Adjustable

From Independence (1947) until the early 1990s, India maintained a fixed-but-adjustable exchange rate regime. The rupee was pegged first to sterling (reflecting colonial-era trade patterns), then (from 1975) to a basket of currencies of India's major trading partners (with the currency weights kept confidential — a persistent source of opaqueness). The peg was adjusted periodically — typically downward — as India's persistent inflation differential with trading partners eroded the rupee's real exchange rate. Devaluations were infrequent, politically traumatic, and — because they were resisted until a crisis forced them — large when they occurred. The most significant devaluation before 1991 was in 1966 (the rupee was devalued from INR 4.76 to INR 7.50 per USD — a 36.5% devaluation — under pressure from the World Bank and the US, in a politically controversial decision that contributed to the Congress Party's electoral losses in 1967).

5.2 The 1991 Crisis and Devaluation

The 1991 BOP crisis (discussed in Week 4) forced a fundamental break with the fixed-but-adjustable regime. In July 1991, the RBI devalued the rupee in two steps: first by approximately 9% (from INR 21.2 to INR 23.0 per USD) on 1 July, and then by a further approximately 11% on 3 July (to INR 25.95 per USD). The cumulative devaluation was approximately 18%. The devaluation was a condition of the IMF's emergency lending programme and was designed to restore India's export competitiveness and to close the gap between the official exchange rate and the parallel (hawala) market rate.

5.3 The Liberalised Exchange Rate Management System (LERMS, 1992)

In March 1992, the government introduced the Liberalised Exchange Rate Management System (LERMS), a transitional dual exchange rate system:

• Official Rate: For specified government transactions, essential imports (crude oil, fertilisers, defence equipment), and debt-service payments — the rate was administered by the RBI.
• Market Rate: For all other transactions (exports, non-essential imports, remittances, capital flows) — the rate was determined by market forces in the interbank FX market.

Exporters were required to surrender 40% of their foreign exchange earnings at the official rate and could sell the remaining 60% at the market rate — an implicit tax on exports (because the official rate was more appreciated than the market rate). This was a classic transitional arrangement: it maintained some control over essential imports and debt payments while allowing the market to discover the rupee's true value for most transactions.

5.4 Unification and the Move to a Market-Determined Rate (1993)

In March 1993, the dual-rate system was unified. The rupee became fully convertible on the Current Account (meaning exporters could retain and sell their foreign exchange earnings at market rates, and importers could purchase foreign exchange at market rates for all Current Account transactions without RBI approval). The rupee remained (and remains) not fully convertible on the Capital Account — Foreign Direct Investment and Foreign Portfolio Investment are permitted subject to sectoral caps and regulatory approvals, but Indian residents cannot freely convert INR into foreign currency for capital account transactions (overseas portfolio investment, outward bank deposits, real estate purchases abroad) beyond specified limits (such as the Liberalised Remittance Scheme, currently USD 250,000 per resident individual per year).

5.5 The De Facto Managed Float (1993–Present)

Since unification in 1993, India's de jure regime has been a "market-determined exchange rate." The de facto regime is a managed float with the following characteristics:

• No publicly announced target or band: The RBI does not declare a target exchange rate or a preferred range. However, the market infers RBI tolerance levels from its intervention patterns — the "RBI put," as market participants informally refer to it (the perception that the RBI will intervene to support the rupee if it depreciates too sharply).
• Asymmetric intervention: The RBI's intervention is asymmetric — it intervenes much more aggressively to prevent appreciation (buying USD, accumulating reserves) than to prevent depreciation (selling USD, drawing down reserves). This asymmetry reflects India's structural BOP position (a persistent CAD means the natural tendency is toward depreciation) and the RBI's preference for a competitive exchange rate to support exports and growth. The asymmetry has produced India's massive reserve accumulation — from approximately USD 5 billion in 1991 to over USD 600 billion in 2024.
• Volatility smoothing, not level targeting: The RBI's stated policy is to "smooth excessive volatility" rather than to target a specific exchange rate level. The RBI intervenes to prevent disorderly market conditions — sharp, self-reinforcing movements driven by herding and panic rather than fundamentals — but does not resist sustained, fundamentals-driven movements. The distinction is subtle: the RBI would intervene if the rupee fell from 83 to 86 in a single week driven by FPI outflows (a disorderly move), but might tolerate the same 3-rupee depreciation spread over six months if it reflected a widening CAD (a fundamentals-driven move). In practice, the line between "volatility" and "level" is blurry, and the RBI's tolerance for depreciation has varied over time with the inflation environment and political pressure.
• Capital account management as a complementary tool: India's managed float is supported by an actively managed capital account. The RBI periodically tightens or loosens capital controls on both inflows and outflows to manage exchange rate pressure without exhausting reserves. During the 2013 Taper Tantrum, the RBI tightened outflows (reducing the LRS limit, imposing restrictions on gold imports). During periods of excessive capital inflows (2007–08, 2017, 2021), the RBI has tightened inflows (reducing FPI debt limits, imposing macroprudential measures on bank foreign borrowing). Capital controls are the third tool — alongside interest rates and FX intervention — that give India's managed float its durability.

5.6 The IFM Implications of India's Managed Float

For the Indian financial manager, the managed float creates a distinctive risk environment:

• The "RBI Put" reduces tail risk: The market's perception that the RBI will intervene to prevent catastrophic rupee depreciation reduces the extreme-left-tail risk for Indian firms with unhedged USD liabilities. This perception is not costless — it may encourage firms to under-hedge, creating vulnerability if the RBI's tolerance for depreciation shifts (as it did in 2013 and 2018). The financial manager who relies on the "RBI put" is effectively betting that the RBI's intervention capacity (USD 600+ billion in reserves) and willingness exceed the market pressure — a bet that is usually right but, when wrong, is catastrophic.
• The managed float does not eliminate currency risk — it changes its character: Under a free float, the rupee would be more volatile day-to-day but would adjust continuously to fundamentals — there would be fewer large, discontinuous jumps. Under India's managed float, the RBI absorbs volatility in normal times (compressing daily movements), but the accumulation of suppressed pressure can lead to large, discontinuous adjustments when the RBI's tolerance is breached — the "dam breaking" dynamic. The financial manager faces less day-to-day noise but greater tail risk of large moves.
• The regime shapes which firms survive: A persistently undervalued real exchange rate (which the RBI's asymmetric intervention tends to produce) subsidises exporters and penalises importers. Indian IT services firms (natural beneficiaries of a weak rupee) have thrived; firms dependent on imported inputs without pricing power (portions of the manufacturing sector) have struggled. The exchange rate regime is not neutral — it shapes the industrial structure. The financial manager must understand not just the current exchange rate but the regime that produces it, because the regime determines the distribution of risks and returns across sectors.
