Anatomy of the Surge
The massive inflow wasn't a random event but a direct result of a strategic move by the Reserve Bank of India (RBI). In mid-2026, the central bank introduced a special concessional swap facility for banks mobilizing fresh FCNR(B) deposits. This measure,
active until September 30, 2026, effectively reduced hedging costs for banks, allowing them to offer much more attractive interest rates to Non-Resident Indians (NRIs). Banks aggressively took advantage of this window, leading to a sharp rise in deposits from about $32.6 billion to over $60.5 billion in under two months.
FCNR Deposits: A Refresher
A Foreign Currency Non-Resident, or FCNR(B), account is a fixed deposit that NRIs, Persons of Indian Origin (PIOs), and Overseas Citizens of India (OCIs) can open with Indian banks. Its primary feature is that the deposit is held in a foreign currency, such as US Dollars, British Pounds, or Euros, among others. This shields the depositor from the risk of currency fluctuations between the Indian Rupee and their home currency. Unlike NRE or NRO accounts, FCNR accounts are exclusively term deposits, typically for tenures ranging from one to five years.
The All-Important Interest Rates
The key driver behind the recent surge is interest rates. Thanks to the RBI's measures, banks have been offering competitive rates, with some reaching as high as 6.6% on certain US Dollar deposits. These rates are not uniform; they vary significantly based on the bank, the currency, the deposit amount, and the tenure. For instance, a deposit over $4 million might fetch a higher rate than a smaller one at the same bank. This underscores the headline's core message: it is essential for prospective depositors to compare offerings from various banks to secure the best possible return.
Navigating Key Rules and Restrictions
While the returns are attractive, FCNR deposits come with a clear set of rules. The tenure is fixed, typically between one and five years. A critical point to note is that no interest is paid if the deposit is withdrawn before one year. The special deposits mobilized under the current RBI scheme even have a mandatory one-year lock-in period. Funds for these deposits must be remitted from overseas or transferred from an existing NRE account. Both the principal amount and the interest earned are fully repatriable, meaning they can be transferred back abroad without restrictions.
The Tax Advantage
One of the most significant advantages of an FCNR deposit is its tax treatment in India. The interest earned on these deposits is completely exempt from income tax in India for eligible NRIs. This makes it a highly tax-efficient way to grow foreign currency savings. Because of this tax-free status and protection from currency risk, FCNR accounts are a popular choice for NRIs looking for safe, predictable returns on their overseas earnings.
