Should RBI Defend Rupee or Let It Float?
SHOULD RBI DEFEND RUPEE, OR LET IT FIND ITS OWN LEVEL
Why in the News?
- The Indian rupee has witnessed a sharp depreciation against the US dollar, triggering concerns about the stability of the Indian economy.
- Policymakers are debating whether the Reserve Bank of India should actively defend the rupee or allow market forces to determine its value.
- The rupee’s exchange rate is determined by demand and supply in the foreign exchange (forex) market.
- Higher demand for dollars by Indians — for imports, foreign travel, education, or overseas investments — weakens the rupee when compared to the dollar.
- Conversely, stronger demand for rupees by foreigners through investments and purchases of Indian goods helps support the rupee.
- The recent fall in the rupee reflects underlying weaknesses in the Indian economy, including external sector pressures and rising demand for foreign currency.
How Can the Rupee’s Exchange Rate Be Artificially Improved?
- Indians are not permitted to freely hold and use US dollars within the domestic economy; most dollar inflows ultimately come under the control of the Reserve Bank of India.
- The RBI can intervene in the foreign exchange market by selling dollars from its forex reserves.
- When the RBI sells dollars, the supply of dollars in the market increases, reducing upward pressure on the dollar’s value.
- In exchange for dollars, the RBI buys rupees, thereby increasing the demand for the rupee.
- This process helps strengthen or stabilise the rupee’s exchange rate temporarily.
- Such intervention by the central bank is commonly referred to as “defending the rupee.”
How Does the RBI Decide When to Defend the Rupee?
- The RBI officially maintains that it does not target any fixed exchange rate for the rupee.
- Its primary objective is to ensure orderly movement in the foreign exchange market and prevent excessive volatility.
- The RBI intervenes when it believes the rupee is appreciating or depreciating too rapidly against other currencies, following a precautionary principle to prevent market disruptions.
- Such interventions are aimed at maintaining financial stability in the economy.
- Sharp fluctuations in exchange rates can create uncertainty for consumers, businesses, traders, students studying abroad, and import-export activities.
- Therefore, RBI actions are generally intended to smoothen extreme currency movements rather than permanently fix the rupee’s value.
Does Defending the Rupee Work?
- RBI intervention can be effective in the short term by stabilising sudden volatility in the currency market.
- India has used its foreign exchange reserves over the years to prevent excessive depreciation of the rupee.
- By selling dollars from its reserves, the RBI has managed to moderate sharp currency fluctuations.
- However, continuous intervention raises concerns about the sustainability of depleting forex reserves.
- Despite repeated interventions, the rupee has eventually continued to weaken over time, indicating the limitations of artificial support measures.
- This raises questions about whether prolonged defence of the rupee can succeed against deeper structural economic pressures.
Why Can’t the RBI Defend the Rupee Like Earlier?
Need to Maintain Adequate Import Cover
- Policymakers prefer maintaining sufficient forex reserves to finance essential imports for several months, usually around 10 months of import cover.
- Excessive use of reserves to defend the rupee can reduce this safety buffer and expose the economy to external shocks.
- Therefore, the RBI cannot indefinitely continue selling dollars without risking external sector vulnerability.
Nature and Quality of India’s Forex Reserves
- A significant portion of India’s forex reserves comes from foreign investments rather than export earnings.
- Such foreign capital is volatile and can leave the country quickly if investors lose confidence or find better opportunities elsewhere.
- This makes a large part of India’s forex reserves relatively unstable in comparison to countries with sustained trade surpluses.
- Unlike countries such as China, which accumulate forex through exports, India relies heavily on capital inflows despite running trade deficits.
- As India imports more than it exports, its forex reserves are more vulnerable to sudden capital outflows.
- Consequently, the RBI faces greater constraints in aggressively defending the rupee for prolonged periods.
Why Not Let the Rupee Find Its Own Level?
Economic Argument in Favour of a Freely Falling Rupee
- Many economists argue that the rupee should be allowed to depreciate naturally according to market forces.
- A weaker rupee can make Indian exports cheaper and more competitive in global markets.
- At the same time, imports become more expensive, reducing domestic demand for foreign goods.
- This combination is expected to reduce India’s trade deficit by encouraging exports and discouraging imports.
- Allowing the rupee to adjust freely would also reduce pressure on the Reserve Bank of India to continuously spend foreign exchange reserves defending the currency.
- It could additionally prevent the need for austerity measures or excessive ex post facto policy intervention by the government.
Why This Approach May Not Work Effectively in India
High Dependence on Re-Exports
- A significant share of India’s exports depends on imported inputs and raw materials; some estimates place this at nearly 40%.
- When the rupee weakens, imported components become more expensive for Indian producers.
- Although exports become cheaper for foreign buyers, the higher import cost offsets much of the competitive advantage.
- As a result, depreciation may not significantly improve export earnings or reduce the trade deficit.
India as a Price-Taker in Global Markets
- In several sectors, especially textiles and low-cost manufacturing, India is a price-taker rather than a price-setter.
- Indian exporters face intense competition from countries such as Bangladesh.
- Foreign buyers often demand lower prices when the rupee depreciates, limiting gains for Indian exporters.
- Therefore, a weaker rupee may not substantially increase export profitability, contrary to textbook economic assumptions.
Depreciation Can Trigger Further Depreciation
- Continuous weakening of the rupee can create expectations of further decline in the currency’s value.
- Importers may begin purchasing larger quantities of dollars in anticipation of future depreciation.
- Increased demand for dollars further weakens the rupee, creating a self-reinforcing cycle.
- Thus, currency depreciation can sometimes intensify rather than stabilise exchange rate pressures.
Exporters May Delay Dollar Inflows
- Exporters expecting the rupee to weaken further may postpone converting their dollar earnings into rupees.
- Delayed inflow of dollars reduces dollar supply in the domestic forex market.
- This shortage pushes up the price of the dollar further and accelerates rupee depreciation.
Impact on Foreign Investments
- A rapidly depreciating rupee can discourage foreign investors from investing in India.
- Even if Indian financial markets generate strong returns, currency depreciation reduces actual returns in dollar terms for foreign investors.
- For example, a 10% return in Indian markets combined with a 5% fall in the rupee results in only about 5% effective returns for a foreign investor.
- Expectations of further depreciation may cause investors to delay or withdraw investments from India.
- Reduced capital inflows can widen India’s Balance of Payments deficit and place additional downward pressure on the rupee.
Overall Conclusion
- While allowing the rupee to find its market-determined level appears theoretically efficient, India’s structural economic conditions complicate the outcome.
- Factors such as dependence on imported inputs, speculative behaviour, and vulnerability to capital outflows may reduce the benefits of depreciation and even worsen the rupee’s decline.
Way Forward
Strengthen India’s External Sector
- Reduce excessive dependence on imports, especially in critical sectors such as energy, electronics, and defence.
- Promote export diversification and move towards higher value-added manufacturing.
- Encourage domestic production under initiatives such as Make in India and Production-Linked Incentive (PLI) schemes.
Maintain Adequate Forex Reserves
- The Reserve Bank of India should continue maintaining sufficient foreign exchange reserves to manage sudden external shocks and currency volatility.
- Forex intervention should focus on preventing excessive fluctuations rather than defending any fixed exchange rate.
Improve Export Competitiveness
- Enhance infrastructure, logistics, and ease of doing business to reduce export costs.
- Move from being a “price-taker” to a “value creator” by focusing on technology-intensive and branded exports.
- Support MSMEs and labour-intensive sectors to improve global competitiveness.
Attract Stable Capital Inflows
- Encourage long-term foreign direct investment (FDI) instead of relying excessively on volatile portfolio investments.
- Ensure policy stability, regulatory predictability, and macroeconomic discipline to maintain investor confidence.
Reduce Trade Deficit
- Promote import substitution in strategic sectors while avoiding excessive protectionism.
- Increase domestic energy security through renewable energy expansion and diversification of oil sources.
- Encourage exports of services, digital products, and high-value manufacturing goods.
Ensure Macroeconomic Stability
- Maintain prudent fiscal policy and control inflation to support currency stability.
- Coordinate monetary and fiscal policies to strengthen market confidence in the Indian economy.
- Structural reforms aimed at productivity growth and employment generation can improve long-term rupee stability.
Adopt a Balanced Exchange Rate Approach
- India should avoid both excessive artificial defence of the rupee and uncontrolled depreciation.
- A calibrated, market-linked exchange rate regime with limited RBI intervention is more sustainable in the long run.
- The focus should be on strengthening economic fundamentals rather than merely managing the currency level.
Mains question
“Should the RBI actively defend the rupee against depreciation or allow market forces to determine its value? Discuss the economic implications of both approaches for India’s external sector and macroeconomic stability.”
