Rupee Breaches 91: Structural Crisis or Temporary Shock?

Introduction: Rupee Crosses a New Threshold

The Indian rupee has weakened past the significant 91-per-dollar mark, a development that reflects more than just short-term market volatility. This depreciation is the result of a convergence of external pressures and domestic structural imbalances. Key drivers include persistent capital outflows, a widening trade deficit, and geopolitical trade tensions, particularly with the United States. The Reserve Bank of India (RBI) has opted to manage the currency's decline by smoothing volatility rather than defending a specific exchange rate, signaling a policy acceptance of a weaker rupee. This situation has shifted the market's focus from whether the rupee will weaken further to how this managed depreciation will unfold.

Asia's Worst Performer in 2025

The rupee's performance in 2025 has been notably poor, making it Asia's worst-performing currency with a year-over-year depreciation of 5.54%. The currency breached the 90-per-dollar level in early December before continuing its slide. What makes this decline particularly concerning is that it has occurred without a significant broad-based rally in the US dollar. The dollar index has remained largely range-bound, indicating that the rupee's weakness is driven primarily by India-specific factors. This divergence from other Asian currencies points to internal economic strains rather than just global financial conditions.

Core Drivers: A Storm of Factors

Several interconnected factors are fueling the rupee's decline. On the external front, the imposition of up to 50% tariffs on Indian exports by the United States has severely hampered export competitiveness. This has been compounded by a risk-averse global environment and higher overseas interest rates, which draw capital away from emerging markets. Domestically, the merchandise trade deficit has ballooned, exceeding $12 billion in October 2025. This is driven by strong import demand for oil and electronics, coupled with slowing exports. Furthermore, foreign portfolio investors (FPIs) have pulled out an estimated $16-18 billion, while importers scramble to cover their dollar exposures and exporters hold back on converting their dollar receipts, creating a one-sided market.

The RBI's Managed Float Strategy

The International Monetary Fund (IMF) classifies India's exchange rate regime as a "crawl-like arrangement." This means the RBI is guiding the rupee along a gradual depreciation path, intervening only to prevent disorderly movements rather than defending a specific level. While this approach provides flexibility, it also has costs. When the RBI sells dollars to support the rupee, it often enters into forward contracts to buy them back later. This can create future demand for dollars, effectively planting the seeds for further depreciation. The central bank's actions suggest a long-term policy of allowing the currency to adjust to underlying economic fundamentals.

Economic Impact Across Five Channels

The persistent weakness of the rupee is expected to impact the Indian economy through five primary channels. First, it creates a significant hit to consumer and business sentiment, raising policy uncertainty. Second, it affects growth dynamics; while costlier imports may contract, any corresponding improvement in exports tends to be modest and delayed. Third, it fuels inflation as the cost of imported goods and raw materials rises. Fourth, it influences external balances, with the trade deficit potentially improving over time but facing near-term headwinds from trade deal uncertainties. Finally, it has fiscal implications, potentially increasing subsidy costs for items like fertilizers and LPG while also boosting the RBI's earnings from foreign exchange reserves, which could lead to a larger dividend for the government.

The Debate: Structural Flaw or Cyclical Pressure?

There are two competing views on the rupee's decline. One perspective argues that this is a structural crisis rooted in fundamental weaknesses. This view highlights India's high import intensity in manufacturing, which means a weaker rupee raises input costs and erodes competitiveness, debunking the myth that depreciation automatically boosts exports. It also points to constraints in the RBI's usable reserves and the risks associated with a global dollar shortage. The opposing view contends that the depreciation is a manageable, cyclical issue driven primarily by external factors like US tariffs. Proponents of this view emphasize India's strong macroeconomic fundamentals, including robust GDP growth and adequate forex reserves, suggesting the currency's weakness is a temporary aberration that will correct once trade tensions ease.

Outlook and Future Scenarios

The future trajectory of the rupee appears heavily dependent on the outcome of trade negotiations between India and the United States. The market consensus points to a binary outcome. A successful trade deal by early 2026, which reduces tariffs, could see the rupee stabilize in the 88-91 range. However, a failure to reach an agreement would likely lead to continued pressure, potentially pushing the currency into the 92-95 range as trade deficits persist. In the long term, the most probable scenario is a managed glide path, with the RBI continuing to smooth out volatility while allowing for a gradual depreciation aligned with economic realities.

Conclusion

The rupee's fall past the 91-per-dollar mark is not a simple market event but a reflection of a complex interplay between external shocks and domestic economic constraints. While India's strong fundamentals, such as substantial forex reserves, provide a cushion against a disorderly collapse, the episode underscores the limitations of relying on currency depreciation as a tool for economic growth. Ultimately, India's long-term economic strength will be determined by its ability to achieve sustainable competitiveness, ensure capital stability, and maintain policy credibility, rather than by the nominal value of its currency.
