India's foreign exchange reserves have climbed to an unprecedented $729.33 billion as of August 21, 2026, marking a new all-time high. This significant surge is primarily attributed to a substantial inflow of Foreign Currency Non-Resident (Bank), or FCNR(B), deposits, facilitated by a concessional swap facility introduced by the Reserve Bank of India (RBI).
FCNR(B) Deposits Drive Record Growth
Between June 8 and August 21, FCNR(B) deposits recorded an impressive accretion of nearly $65.4 billion. This rapid build-up pushed the total reserves past the previous peak of $728.49 billion, recorded earlier in February. The RBI's special FCNR(B) swap window played a crucial role, enabling banks to attract foreign currency deposits from non-resident Indians (NRIs) by offering attractive interest rates, reportedly up to 7.4%.
This initiative not only bolstered the nation's dollar liquidity within the banking system but also helped mitigate immediate exchange-rate risks for participating financial institutions. The enhanced reserve levels significantly strengthen the RBI's capacity to intervene in the currency market, thereby curbing abrupt and disorderly movements of the Indian rupee.
Economists Caution on External Liabilities
While the record accumulation provides a stronger buffer against external shocks, economists like Manoranjan Sharma, Chief Economist at Infomerics Ratings, caution that these deposit-led inflows represent an "exceptional inflow episode" rather than a fundamental improvement in India's trade balance. Sharma highlighted that these inflows, while beneficial for near-term stability, simultaneously create external liabilities that could reverse when incentives expire or global yields shift.
"The record stock improves near-term stability, but should not mean that structural current-account vulnerabilities, especially oil dependence, have disappeared—no way!" Sharma emphasized, pointing to ongoing structural risks despite the robust reserve levels.
Context of Rupee Pressure
The RBI's measures come amidst persistent pressure on the Indian rupee. Foreign portfolio investors withdrew approximately $19 billion from Indian markets in 2025, followed by another $24 billion during the first five months of 2026. The rupee had neared ₹97 against the US dollar in mid-May and remains about 8.1% weaker compared to a year prior.
Beyond FCNR(B) deposits, the concessional swap facility also enabled banks and public sector undertakings to raise an additional $4.86 billion through overseas foreign-currency borrowings and $2.59 billion via external commercial borrowings, further contributing to the inflow of foreign currency.
