1. Macroeconomic Context and the Rupee Paradox
India’s recent rupee depreciation presents a paradox against the backdrop of strong macroeconomic fundamentals. The economy is projected to grow at 7.4%, reflecting robust domestic demand and investment momentum. Inflation has remained subdued, with CPI inflation at 1.33% at end-2025, below the RBI’s lower tolerance band for the fourth consecutive month, indicating price stability.
The external sector indicators also appear manageable. The current account deficit (CAD) in the first half of 2025–26 stood at 0.76% of GDP, significantly lower than 1.35% in the previous year. Such figures would typically support currency stability rather than depreciation.
Despite these positives, the rupee has depreciated by about 6% since April 2025. This divergence raises questions about the limits of macroeconomic fundamentals in explaining exchange rate movements, especially in an increasingly globalised and geopolitically sensitive financial system.
The core governance insight is that exchange rates are influenced not only by growth and inflation but also by expectations and cross-border capital behaviour. Ignoring this disconnect risks misdiagnosing policy responses and underestimating non-economic drivers of financial stability.
2. Capital Outflows as the Primary Driver
The principal factor behind the rupee’s fall is sustained capital outflows rather than trade imbalances. While India’s combined merchandise and services trade deficit widened to 88.43 billion a year earlier, it remains insufficient to explain the sharp currency movement.
In contrast, capital flows show a clear reversal. Net capital inflows of 3,900 million in the same period of 2025. Such outflows exert immediate pressure on the exchange rate through foreign exchange market transactions.
Capital movements are often more volatile and sentiment-driven than trade flows. When portfolio investors exit equity and debt markets, the resulting demand for foreign currency accelerates depreciation and can trigger self-reinforcing cycles of outflows.
Key capital flow data:
- Net capital inflows (Apr–Dec 2024): $10.6 billion
- Net capital outflows (Apr–Dec 2025): $3.9 billion
- Rupee depreciation since April 2025: ~6%
From a policy perspective, unchecked capital outflows can destabilise both currency and equity markets. If ignored, they raise the cost of capital, weaken investor confidence, and complicate macroeconomic management.
3. Geopolitical and Diplomatic Factors Behind Capital Flight
Unlike earlier episodes of rupee depreciation driven by monetary tightening in advanced economies, the current episode is shaped by geopolitical pressures. The U.S. has imposed a cumulative 50% tariff on Indian exports—initially 25% on a “reciprocal” basis and an additional 25% linked to India’s crude oil imports from Russia.
Further uncertainty stems from U.S. threats to impose another 25% tariff on countries trading with Iran, a category that technically includes India, even though trade with Iran accounts for only 0.15% of India’s total trade. These actions have heightened investor uncertainty rather than altering India’s economic fundamentals.
The prolonged stalemate in India–U.S. trade negotiations has amplified perceptions of policy risk. As a result, capital outflows are driven more by fears of hostile trade relations than by domestic macroeconomic weakness.
The developmental logic is that in a world where tariffs are weaponised, diplomacy becomes a macroeconomic stabiliser. Failure to address such non-economic pressures can prolong currency stress despite sound fundamentals.
4. RBI’s Exchange Rate Regime and Intervention Strategy
India shifted to a market-determined exchange rate regime in 1993, allowing the rupee’s value to be set by demand and supply. However, this framework explicitly permits RBI intervention to manage excessive volatility rather than to fix or peg the exchange rate.
Over time, RBI practice suggests that “reducing volatility” includes moderating sharp depreciations to prevent disruptive shocks. Sudden currency movements impose costs on importers, borrowers with foreign currency exposure, and overall financial stability.
The current episode introduces a new dimension: depreciation driven by non-economic and geopolitical factors. While intervention cannot reverse underlying capital outflows, it can smoothen the pace of adjustment and prevent panic-driven overshooting.
RBI’s intervention logic:
- Not to prevent depreciation permanently
- To reduce abrupt fluctuations
- To allow a gradual, orderly adjustment
Institutionally, clarity on the scope of “volatility management” enhances policy credibility. If such intervention logic remains ambiguous, market expectations may become misaligned, increasing instability.
5. Limits of Devaluation as a Policy Response
Currency depreciation is sometimes viewed as a tool to boost exports, but its effectiveness in India’s case is limited. The import content of exports has increased, diluting the competitiveness gains from a weaker rupee. Consequently, export stimulus from devaluation is moderated.
On the import side, India’s basket is dominated by essential goods. Crude oil alone constitutes about 25% of total merchandise imports. A weaker rupee directly raises import costs, which can feed into domestic inflation despite currently low CPI levels.
Moreover, devaluation is typically justified when domestic inflation significantly exceeds that of trading partners. At present, India’s inflation is not higher than that of many developed economies, making a case for devaluation weak when assessed through the Real Effective Exchange Rate (REER) framework.
The governance lesson is that devaluation without structural export gains or inflation differentials risks higher prices without competitiveness benefits. Ignoring this can undermine price stability and real incomes.
6. Financial Markets, Expectations, and Spillover Effects
Capital outflows triggered by equity sales directly affect stock markets and wealth perceptions. Each episode of rupee depreciation raises the expected rupee returns required by foreign investors, further discouraging inflows and accelerating exits.
This feedback loop can magnify volatility across asset classes. While the full impact of U.S. tariffs is expected in 2026–27, anticipatory behaviour by investors is already influencing currency and capital markets.
Consequently, macroeconomic management must account for expectations and signalling effects, not merely contemporaneous data. Exchange rate stability thus becomes intertwined with financial market confidence.
If expectation-driven dynamics are overlooked, policy responses may lag market reactions, deepening volatility and increasing the eventual adjustment cost.
7. Way Forward: Diplomacy and Monetary Management
The immediate trigger for the rupee’s weakness lies outside conventional economic levers. An early diplomatic understanding between India and the U.S. is crucial to restoring investor confidence and reversing capital outflows.
Meanwhile, the RBI’s role is necessarily limited to smoothing volatility rather than targeting a specific exchange rate level. Clear communication on intervention objectives can anchor expectations until external uncertainties ease.
Policy priorities:
- Early resolution of trade and tariff disputes through diplomacy
- Continued RBI intervention to smooth excessive volatility
- Monitoring capital flow dynamics alongside trade indicators
Strategically, aligning foreign policy engagement with macroeconomic stability tools is essential. Ignoring either dimension risks prolonged currency stress and higher adjustment costs.
Conclusion
The recent depreciation of the rupee underscores the growing influence of geopolitics and capital flows over exchange rate dynamics, even amid strong domestic fundamentals. Sustainable currency stability will depend not only on sound macroeconomic management but also on effective diplomacy and credible institutional responses. Over the long term, integrating external economic relations with financial stability objectives will be critical for India’s development trajectory.
