This detailed analysis covers the transition from the Bretton Woods era to Capital Account Convertibility, highlighting the pivotal reforms and acts that shaped the Indian Rupee's global standing.

🎯 In this chapter, you will understand:

  • The journey of India's exchange rate policy from fixed ties to flexible market mechanisms.
  • How the breakdown of the Bretton Woods System led to the currency basket framework in .
  • The role of LERMS and MLERMS in establishing full current account convertibility.

💡 Why this topic matters: Understanding how India managed its currency over the decades explains how the Reserve Bank of India maintains national financial stability and balances trade in a shifting global economy.

🧠 Core Idea: India transformed its exchange rate strategy from a rigid tie with foreign currencies into a dynamic, market-driven floating system to protect and grow its economy.

Evolution of Indian Exchange Rate Policy: A Historical Journey from 1947 to Modern Era

The historical narrative of India's currency management reflects a shift from rigid colonial ties to a market-driven global integration. The story begins with the Indian Rupee tethered firmly to the British Pound Sterling, navigating through the collapse of international systems and domestic economic crises to emerge as a managed floating currency.

  • (i) The early years were defined by the Par Value System under the IMF guidelines.
  • (ii) Systematic transitions occurred from pegged regimes to a basket of currencies approach.
  • (iii) Modern policy emphasizes Real Effective Exchange Rate (REER) monitoring and forex reserve adequacy.

📌 Points to remember: India transitioned step-by-step from a pound-pegged currency to a managed float monitored through currency baskets and real effective exchange rates.

The Era of Fixed Regimes: Exchange Rate Under Bretton Woods System

Following Independence, India adhered to the global financial architecture established by the Bretton Woods Agreement, anchoring its currency landscape to international protocols.

  • The Sterling Connection and IMF Compliance

    Historically, the Indian rupee was pegged to the pound sterling until the late 1960s, maintaining a stable but dependent relationship with the UK economy.

    • Gold Par Value and RBI Intervention

      As a member of the International Monetary Fund (IMF), India declared a par value of the rupee in terms of gold. The Reserve Bank of India (RBI) maintained this value within a strict ±1% band, using the pound sterling as the primary intervention currency for all market operations.

    • The 1966 Devaluation Milestone

      In June 1966, a significant shift occurred when the rupee was devalued to address economic pressures. The new par value was set at 0.118489 grams of gold per rupee, which fixed the rupee-sterling rate at GBP 1 = Rs. 18.

📌 Points to remember: Under Bretton Woods, India defined its rupee value using gold and used the British pound for market adjustments until economic strain forced the devaluation.

Navigating Uncertainty: Transition After the Collapse of Bretton Woods

The global breakdown of fixed exchange rates in forced India to seek a more flexible framework for the Indian Rupee amidst mounting international volatility.

  • From Dollar Pegging to the Currency Basket System

    Between and , India experimented with various anchors to protect the rupee's value from international volatility.

    • (i) In August 1971, the rupee was briefly pegged to the US dollar at US$1 = Rs. 7.50, though the RBI still used sterling for interventions.
    • (ii) Following the Smithsonian Agreement in , the rupee was re-pegged to the pound sterling with a wider ±2.25% band.
    • (iii) By , the floating of the pound caused the rupee to fluctuate uncontrollably, leading to domestic instability.
    • (iv) By September 1975, Britain's weak economy led to a 20% depreciation of the pound, causing an automatic and harmful depreciation of the rupee and fueling inflation in India.
    • The Secret Basket of 1975

      On September 25, 1975, India finally delinked from sterling and moved to a basket of currencies. The specific weights of this basket were strictly confidential to prevent market speculation, allowing the RBI the discretion to adjust weights based on India's trade patterns without external interference.

📌 Points to remember: Uncontrolled inflation and the pound's drop forced India to cut its direct link to sterling in and adopt a confidential multi-currency basket.

The Reform Era: Liberalised Exchange Rate Management System (LERMS)

The forex crisis of 1990–91 acted as a catalyst for sweeping economic liberalisation in the Indian financial sector, resetting structural mechanisms entirely.

  • Introduction of the Dual Exchange Rate System

    On March 1, 1992, the RBI introduced LERMS, a transitional path toward a market-determined exchange rate.

    • Key Mechanisms of LERMS

      It introduced Rupee convertibility for all approved external transactions based on a dual pricing mandate. Under The 60:40 Rule, exporters could sell 60% of receipts at market-determined rates, while 40% had to be surrendered to the RBI at the official exchange rate. This dual system allowed the government to subsidize essential imports while encouraging exports.

📌 Points to remember: Introduced in , LERMS created a dual exchange system where 60% of foreign earnings were traded at market rates and 40% at official RBI rates.

Full Current Account Convertibility: Modified LERMS (1993)

Building on the success of , India moved toward a unified exchange rate to further integrate with the global economy and strip away dual rate distortions.

  • The Birth of MLERMS and Market Determination

    The Reserve Bank of India (RBI) made the Indian rupee fully floating on the current accounteffective March 1, 1993.

    • (i) Under the Modified Liberalised Exchange Rate Management System (MLERMS), the dual rate was abolished in favor of a unified market rate.
    • (ii) All transactions were routed through Authorised Dealers (ADs) at prevailing market prices.
    • (iii) While trade restrictions eased, foreign exchange payments remained under the Exchange Control Regulations to ensure stability.
  • The Sodhani Committee Recommendations (1994–95)

    To deepen the forex market, Mr. O.P. Sodhani chaired an expert group that submitted 33 recommendations in .

    • Banking and Corporate Empowerment

      Banks were granted autonomy to set net overnight positions and gap limits. Permission was granted to invest up to 15% of Tier 1 capital overseas and set FCNR deposit rates. Corporates gained the ability to hedge genuine exposures, though margin trading via EEFCAs was restricted after the Asian Financial Crisis. Meanwhile, RBI intervention was advised to be selective and strategic rather than frequent.

📌 Points to remember: MLERMS unified the exchange rate in , ending dual rates and opening the path for full current account convertibility.

The Final Frontier: Capital Account Convertibility in India

By the late , the focus shifted from simple trade balances to the free movement of capital, led by the analytical framework of the Tarapore Committee.

  • The Tarapore Committee and CAC Framework

    On , the RBI established a committee to chart the path for Capital Account Convertibility (CAC).

    • Defining Convertibility and Liberalisation

      CAC was defined as the freedom to convert local assets into foreign assets (and vice-versa) at market rates. The framework recommended the liberalisation of FDI and the facilitation of portfolio investments while increasing the EEFC entitlement to 50% to support Indian exporters.

    • Exchange Rate and Reserve Adequacy

      The committee proposed a monitoring band of ±15% around the Real Effective Exchange Rate (REER). It established strict benchmarks stating that Forex reserves should cover at least six months of imports, and integrated risk management through Interest Rate Swaps (IRS) and Forward Rate Agreements (FRAs).

📌 Points to remember: The Tarapore Committee set the baseline rules for capital convertibility, recommending a 15% REER band and a minimum 6-month import reserve cover.
