$100 bn in sight: India is rolling in dollars but what about the rupee?
Banks have mobilised over $40 billion in the two months since the Reserve Bank of India (RBI) launched special measures to attract foreign currency deposits, led by FCNR(B) inflows.
Economists project total inflows under the scheme could reach $100 billion.
The stated objective is to strengthen India's external sector buffers and ensure dollar liquidity during global volatility, not to directly boost the rupee's value.
The rupee has remained largely unchanged against the dollar despite the scale of inflows.
FCNR(B) Deposits and the RBI Swap Window
FCNR(B) (Foreign Currency Non-Resident Bank) deposits allow Non-Resident Indians (NRIs) to hold fixed deposits in foreign currency (commonly USD) with Indian banks, insulating depositors from rupee depreciation risk since both principal and interest are denominated in the foreign currency. To make these deposits attractive to banks, the RBI can open a special dollar-rupee swap window that absorbs the banks' currency-hedging cost.
Key Details
- Under the swap mechanism, a bank accepts USD from an NRI as an FCNR(B) deposit, sells the dollars to the RBI, and receives rupees in exchange at the FBIL (Financial Benchmarks India Limited) reference rate; the RBI bears the forward hedging cost rather than the bank.
- The current window (opened roughly June 2026) targets deposits of 3-5 year tenure and was designed after NRI deposit inflows had collapsed to under $1 billion in FY26, down sharply from about $7 billion in FY25.
- A similar RBI swap window was used in 2013 during the "taper tantrum" episode to arrest a sharp rupee slide, mobilising roughly $34 billion at the time — the current scheme is explicitly modelled on that precedent, though analysts note it is unlikely to match the exact 2013 quantum given a narrower interest rate differential today.
- FCNR(B) deposits form part of India's NRI deposit basket, alongside NRE (Non-Resident External, rupee-denominated) and NRO (Non-Resident Ordinary) accounts.
The $40 billion-plus mobilised so far, and the $100 billion projection, are the direct output of this FCNR(B) swap window — a targeted instrument to shore up reserves and forex liquidity rather than a rupee-support measure per se.
Foreign Exchange Reserves Management and RBI's Mandate
The RBI manages India's foreign exchange reserves under the Reserve Bank of India Act, 1934 and intervenes in the currency market to smooth excessive volatility rather than to defend a fixed exchange rate, consistent with India's managed-float exchange rate regime.
Key Details
- India's forex reserves stood at roughly $688.9 billion as of early August 2026, having fallen from a peak of over $700 billion, partly reflecting the RBI's spot-market intervention to defend the rupee.
- Reserve adequacy is typically assessed using import-cover (months of imports the reserves can finance) and the reserves-to-short-term-external-debt ratio, both used by agencies such as the IMF for early-warning assessments.
- The RBI's exchange rate policy objective, as repeatedly stated, is to curb volatility rather than target a specific rupee level — consistent with the "no fixed target" stance described in this episode.
- Complementary tools available to the RBI for external sector management include the forward/swap market, interest rate differentials, and administrative measures on external commercial borrowings (ECBs).
The FCNR(B) scheme functions as a reserve-replenishment and liquidity-buffer tool; the RBI's own framing that this is "not about the rupee" reflects the broader principle that reserves management and exchange-rate-level targeting are distinct policy objectives.
Balance of Payments and Capital Account Flows
The Balance of Payments (BoP) records all economic transactions between residents of a country and the rest of the world, split into the Current Account (trade, services, remittances) and the Capital/Financial Account (investment and deposit flows). NRI deposits are recorded as capital account inflows and are one of the few capital flow categories the RBI can influence directly through interest rate and swap-cost incentives.
Key Details
- Other capital account components include Foreign Direct Investment (FDI), Foreign Portfolio Investment (FPI), and External Commercial Borrowings (ECBs) — all more market-driven and harder for the RBI to directly steer than bank deposit schemes.
- A widening Current Account Deficit (CAD) increases India's need for capital account inflows (like NRI deposits) to maintain overall BoP balance and reserve stability.
- India's remittance inflows (a current account item, distinct from NRI deposits) remain among the highest in the world, providing a separate cushion for the external account.
The FCNR(B)-driven dollar mobilisation is best understood as a capital-account lever the RBI can pull quickly and directly, in contrast to FDI/FPI flows that respond to broader sentiment and cannot be engineered through a single scheme.
- Dollar mobilisation so far under the current scheme: over $40 billion in two months.
- Projected total inflows: up to $100 billion.
- FY26 NRI deposit collapse before the scheme: under $1 billion, down from about $7 billion in FY25.
- India's forex reserves: approximately $688.9 billion as of August 1, 2026, down from a peak above $700 billion.
- Precedent: the 2013 FCNR(B) swap window mobilised roughly $34 billion during the taper tantrum.
- Current scheme tenure targeted: FCNR(B) deposits of 3-5 years.
