Former Indian central bank official: India may need $1 trillion in foreign exchange reserves

India’s foreign exchange buffer may face higher thresholds, as former Reserve Bank of India Vice President Michael Patra stated that reserves may need to reach at least $1 trillion to maintain credible intervention capability. In an article on BasisPoint Insight, Patra viewed this figure as both a financial safeguard and a deterrent against speculative pressure, noting that such a level could make it more difficult for speculative market positions to challenge the central bank. He broke down this estimate into approximately $350 billion for covering one-year external debt and about $650 billion for buffering potential outflows of foreign portfolio capital, in contrast to India’s record reserve level of $728.5 billion reported in February.

Patra’s perspective comes amid a shifting macro backdrop. Before leaving the Reserve Bank of India in early 2025, he led and experienced a strong period of reserve accumulation, during which the central bank absorbed global capital inflows, subsequently using these reserves to smooth currency fluctuations and making the rupee one of the least volatile currencies. However, following the recent depreciation of the rupee to a record low, the Reserve Bank of India has intensified its intervention efforts, as rising crude oil prices related to the Iran war pose risks to India’s oil-import-dependent economy.

Even in the face of these pressures, Patra suggested that the Reserve Bank of India’s approach may continue to lean toward gradual adjustments rather than aggressively defending specific levels. He noted that an annual depreciation of the rupee of around 4% to 5% might roughly align with India’s underlying investment-saving dynamics and added that the central bank has historically sought a more controlled decline rather than sudden shifts. For investors, the conclusion may be that while accumulating reserves remains a strategic priority, policy execution may still tend to favor stability through managed exchange rate movements rather than drastic interventions.
