India's Forex Reserves Drop $11.68B, Ex-RBI Chief Urges $1T Buffer

Introduction

Former Reserve Bank of India (RBI) Deputy Governor Michael Patra has called for India to build a foreign exchange reserve buffer of at least $1 trillion to safeguard the economy against global shocks. His recommendation comes as the country's reserves experienced their steepest weekly decline in over a year, falling by $11.68 billion to $116.81 billion in the week ending March 6, 2026. This sharp drop highlights the increasing pressure on India's external balances and the central bank's active role in managing currency stability.

The Rationale for a $1 Trillion Buffer

According to Patra, the $1 trillion target is not an arbitrary figure but is based on two critical components designed to ensure financial stability. The first requirement is to hold enough reserves to cover all of India's external debt obligations maturing within one year. This buffer is estimated to be between $100 billion and $150 billion. The second, and larger, component is a cushion against sudden and sustained outflows of foreign portfolio investment (FPI). Patra suggests that reserves should cover at least 60-65% of the total stock of FPI, which would require an additional $100 billion to $150 billion. Together, these buffers push the necessary reserve level to the $1 trillion mark, a level Patra believes would be substantial enough to deter opportunistic speculators from betting against the rupee.

Recent Pressures and RBI Intervention

The recent $11.68 billion fall in reserves, from a record $128.49 billion the previous week, was primarily driven by the RBI's aggressive sale of US dollars. The central bank intervened in the currency markets to support the Indian rupee, which has been under significant strain. Key pressures include geopolitical tensions stemming from the Iran war, a resulting surge in global oil prices, and a strengthening US dollar backed by higher bond yields. This intervention underscores the RBI's strategy of using its reserves to absorb external shocks and prevent disorderly movements in the rupee's value.

A Strategic Approach to Currency Management

The RBI's actions are consistent with its long-standing policy of managing volatility rather than targeting a specific exchange rate. Officials, including Patra, have emphasized that the goal is to ensure an orderly market and provide a glide path for the currency. Patra noted that a gradual annual depreciation of 4-5% for the rupee is in line with the country's economic fundamentals, such as its moderate saving-investment gap. The central bank's track record shows it enables this gradual movement rather than allowing abrupt plunges, a strategy made possible by a strong reserve position.

Historical Context of Reserve Accumulation

During his tenure at the RBI, which ended in early 2025, Michael Patra oversaw a significant phase of reserve accumulation. The central bank actively absorbed large global capital inflows, bolstering its financial defenses. In the latter part of his term, these accumulated reserves were strategically deployed to contain currency volatility amid intensifying external shocks. This proactive management helped make the rupee one of the least volatile currencies globally, reinforcing the importance of maintaining a substantial reserve buffer.

A Roadmap to Building Stronger Reserves

Patra has suggested that building the reserves to the desired $1 trillion level could be achieved over a three-year period. This timeline is based on the long-term trend in reserve money expansion, which has averaged between $10 billion and $15 billion annually over the past two decades to meet domestic liquidity requirements. As the RBI accumulates more foreign currency, it will also need to manage the resulting liquidity in the domestic banking system to align with its monetary policy stance.

Managing Liquidity and Economic Stability

To counteract the inflationary impact of adding liquidity to the system through reserve accumulation, Patra proposed the use of sterilization tools. He estimated that sterilizing around $15 billion annually would be necessary to maintain price stability. The uncollateralised standing deposit facility (SDF) is a key instrument for this, providing the RBI with a technically unlimited capacity to absorb excess liquidity from the banking system without needing government securities as collateral. This ensures that the process of building reserves does not disrupt domestic financial conditions.

Key Data on Forex Reserve Fluctuations

India's foreign exchange reserves have shown significant movement over the past year, reflecting the dynamic global economic environment and the RBI's active management. The recent sharp decline follows a period of record highs.

Analysis and Future Outlook

The call for a $1 trillion reserve buffer comes at a critical time. While India's current reserves provide a comfortable import cover of around 11 months, well above the standard benchmark for emerging economies, the global landscape is increasingly uncertain. Geopolitical tensions, volatile commodity prices, and shifting capital flows pose persistent risks. The RBI's ability to navigate these challenges depends heavily on maintaining a credible and substantial reserve position. The recent drawdown demonstrates a shift from a phase of accumulation to active deployment of reserves to defend economic stability.

Conclusion

In conclusion, Michael Patra's proposal for a $1 trillion forex reserve highlights the need for a more robust financial shield in an unpredictable world. The recent decline in reserves serves as a practical reminder of the pressures facing the Indian economy. As the RBI continues to manage currency volatility, the debate over the optimal level of reserves will remain central to India's economic policy. Achieving this ambitious target would significantly enhance the central bank's firepower and reinforce India's resilience against future external shocks.
