Understanding the $28 Billion Inflow
Between early June and late July 2026, Foreign Currency Non-Resident (Bank) or FCNR(B) deposits in the Indian banking system skyrocketed. The total balance jumped from approximately $32.5 billion to over $60.5 billion, marking an astonishing increase
of nearly $28 billion in under 60 days. This surge was a direct response to a special policy window opened by the Reserve Bank of India (RBI) designed to attract stable foreign currency inflows, strengthen the country's balance of payments, and ease pressure on the rupee. The data, shared by the Minister of State for Finance in Parliament, highlighted the scale of the success, with banks aggressively mobilising funds from Non-Resident Indians (NRIs).
What Are FCNR(B) Deposits?
Before diving into the 'why', it's important to understand what FCNR(B) accounts are. Essentially, they are fixed deposit accounts that NRIs, Persons of Indian Origin (PIOs), and Overseas Citizens of India (OCIs) can hold with Indian banks. The key feature is that these deposits are maintained in a foreign currency, such as US Dollars, British Pounds, or Euros, among others. This means the depositor is protected from fluctuations in the Indian rupee's exchange rate. The principal amount and the interest earned are fully repatriable, and the interest is tax-exempt in India, making it an attractive savings tool for the Indian diaspora.
The RBI's Game-Changing Move: Swaps and Tenure Rules
The catalyst for the $28 billion surge was a special concessional swap facility introduced by the RBI on June 8, 2026. In simple terms, the RBI offered to bear the currency hedging costs for banks on fresh FCNR(B) deposits with tenures of three to five years. Normally, banks have to hedge against the risk of currency fluctuations when accepting foreign currency deposits, which adds to their costs. By removing this cost for a specific tenure range (3-5 years) until September 30, 2026, the RBI gave banks a powerful incentive. Furthermore, on June 17, the RBI temporarily removed the interest rate ceiling on these specific deposits, allowing banks to offer much more competitive, higher interest rates to attract NRI funds.
How Tenure Rules Drove the Surge
The focus on the three-to-five-year tenure was a crucial part of the strategy. The RBI's measures were specifically applicable to these longer-term deposits, encouraging banks to lock in stable, long-term foreign currency. Shorter-term deposits were not eligible for the same benefits. As part of the special scheme, the RBI also introduced a mandatory one-year lock-in period, preventing premature withdrawals within the first year to ensure the stability of these new inflows. Banks responded swiftly, with major players like HDFC Bank and ICICI Bank hiking their interest rates for these specific tenures to as high as 6.25% on USD deposits, a very attractive proposition for NRIs.
Implications for the Indian Economy and NRIs
This massive inflow of foreign currency serves multiple purposes for the Indian economy. It bolsters the country's foreign exchange reserves, provides a buffer against external economic shocks, and helps stabilize the rupee. For the banking sector, it provided a much-needed boost to deposit growth, helping to ease liquidity pressures. For NRIs, the scheme presented a limited-time opportunity to earn high, tax-free returns on their foreign currency savings without taking on currency risk. The response was overwhelming, with private sector banks mobilizing the largest share of the inflows, followed by public sector and foreign banks.
