Former Reserve Bank of India Governor D. Subbarao has warned that efforts to correct the rupee against underlying economic fundamentals are "ultimately futile," arguing that policymakers should resist the temptation to rely on expensive short-term fixes when the real problem lies in structural weaknesses.
Speaking on the broader debate around the currency's recent movements, Subbarao said the rupee should be allowed to discover its own level in line with market forces and the economy's external balance. He noted that while the currency has recently recovered after the RBI stepped in to curb dollar demand, such moves do not resolve the deeper causes of pressure on the rupee. In his view, intervention may smooth volatility, but it cannot permanently offset persistent capital outflows or restore investor confidence on its own.
Market Forces Matter
Subbarao's comments come at a time when the rupee has been under close scrutiny amid global dollar strength, shifting capital flows and concerns over India's external financing conditions. The central bank has used a range of tools to reduce demand for dollars and manage disorderly moves in the currency market, helping the rupee regain some ground in recent sessions. But the former governor's message was clear: stabilisation is not the same as correction.
He argued that when a currency is under pressure because of fundamentals, defending it through repeated intervention can become costly and counterproductive. Such measures may buy time, but they do not change the underlying arithmetic of trade, investment flows and domestic policy credibility. For a large emerging economy like India, he suggested, the more durable answer lies in strengthening the conditions that attract long-term foreign capital rather than trying to engineer a stronger exchange rate in isolation.
Subbarao's remarks are particularly relevant for sectors such as automotive, electric vehicles and mobility, which are deeply exposed to currency swings through imported components, battery technology, semiconductors and energy costs. A weaker rupee can raise input costs for manufacturers and squeeze margins, even as it may benefit exporters. For EV makers and auto suppliers, exchange-rate volatility adds another layer of uncertainty to investment planning, pricing and localisation strategies.
Tax Reform As Signal
Beyond currency management, Subbarao pointed to tax reform as a critical lever for improving India's investment climate. He said reforms that make the system more predictable, efficient and investor-friendly would do more to attract foreign investment than short-lived attempts to support the rupee. The implication is that capital flows respond not just to interest-rate differentials or market interventions, but also to the broader credibility of the policy environment.
His comments align with a long-standing view among economists that exchange-rate stability is best achieved through stronger fundamentals: higher productivity, a competitive export base, stable inflation, and a policy regime that encourages durable inflows. In that framework, the rupee's value is not a target to be defended at all costs, but an outcome of economic performance.
For India, the challenge is balancing near-term market management with long-term reform. The RBI's interventions can reduce volatility and prevent speculative overshooting, but they cannot substitute for measures that improve the current account, deepen domestic manufacturing, and sustain foreign direct investment. That is especially important for capital-intensive industries such as automotive and EVs, where global investors look closely at policy consistency, tax treatment and supply-chain resilience before committing large sums.
Subbarao's intervention adds weight to the argument that India's currency debate should not be framed as a choice between intervention and inaction. Rather, it is a question of whether policymakers are willing to accept market-driven adjustment while focusing on the reforms that make the economy more resilient over time. In his telling, trying to force the rupee away from fundamentals may offer temporary comfort, but it is no substitute for the harder work of fixing the structural drivers of capital flight and weak investor sentiment.
