RBI special windows seen big enough to bring in $100B
The Reserve Bank of India's (RBI) special foreign exchange inflow facilities, introduced to support the balance of payments, have already mobilised over USD 40 billion.
Market experts assess that the combined size of these windows could eventually draw in inflows approaching USD 100 billion, well above initial official estimates.
The primary channel driving these inflows is a concessional swap facility on fresh Foreign Currency Non-Resident (Bank) — FCNR(B) — deposits, under which the RBI absorbs part of the hedging cost that banks would otherwise bear when converting foreign currency deposits into rupees.
The stated objectives are to stabilise the rupee's exchange rate, shore up foreign exchange reserves, and contain imported inflation by easing pressure on the currency.
FCNR(B) Deposits and the Concessional Swap Window
FCNR(B) (Foreign Currency Non-Resident Bank) deposits allow Non-Resident Indians (NRIs) to hold fixed deposits in foreign currency with Indian banks, insulating depositors from rupee exchange-rate risk. To incentivise banks to raise more such deposits during periods of currency pressure, the RBI can open a concessional swap window, under which it absorbs a significant part of the hedging cost that banks would normally pay to convert the dollar inflows into rupees for domestic deployment.
Key Details
- The mechanism was first used prominently in September 2013, during the "taper tantrum" period, when the RBI ran a swap window at a concessional rate on 3-year-plus FCNR(B) deposits; that episode mobilised roughly USD 34 billion and is widely credited with stabilising the rupee at the time.
- The current window in use runs from mid-2026, with fresh 3-to-5-year FCNR(B) deposits eligible, and the RBI absorbing a substantial share of the annual hedging cost per dollar mobilised.
- FCNR(B) deposits form part of the capital account of India's Balance of Payments, distinct from current account flows like trade and remittances.
The scale being discussed — approaching USD 100 billion — would make the current episode significantly larger than the 2013 precedent, reflecting a proportionately larger effort to defend the rupee and rebuild reserves.
Balance of Payments (BoP) Framework
The Balance of Payments is a systematic statement of all economic transactions between a country's residents and the rest of the world over a given period, published quarterly by the RBI. It comprises the current account (trade in goods and services, income, and transfers) and the capital account (investments, loans, and deposits such as FCNR(B)); by accounting convention, the BoP always balances, with gaps financed through reserve changes or capital inflows.
Key Details
- A current account deficit (import bill exceeding export earnings) is typically financed through capital account inflows such as FDI, FPI, external borrowings, or NRI deposits.
- Special deposit/swap windows are a capital-account tool specifically used to attract inflows quickly during periods of rupee depreciation or reserve depletion.
- The RBI, under powers rooted in the RBI Act, 1934 (including Section 17 provisions on its business operations), manages and deploys India's foreign exchange reserves.
The special windows are a direct capital-account intervention to offset current-account and portfolio-outflow pressures on the rupee, illustrating how BoP components interact and how policy can selectively boost one component to stabilise the overall external position.
Foreign Exchange Reserves and Import Cover
Foreign exchange reserves — comprising foreign currency assets, gold, Special Drawing Rights (SDRs), and India's reserve position with the IMF — are held by the RBI to manage exchange rate volatility and meet external payment obligations. "Import cover" (reserves expressed as months of import expenditure they can finance) is a standard adequacy metric watched by policymakers and rating agencies.
Key Details
- Reserves support market intervention operations, allowing the RBI to sell dollars to smooth excessive rupee volatility without directly printing money domestically.
- Larger reserves also improve investor confidence and reduce the risk premium on India's external borrowings.
By channeling additional dollar inflows through FCNR(B)-linked swap windows, the RBI directly augments its reserve buffer, improving import cover and its capacity to intervene in the forex market if the rupee comes under renewed pressure.
- Special forex windows had mobilised over USD 40 billion as of the report; some estimates see the total effort scaling toward USD 100 billion.
- The 2013 FCNR(B) concessional swap window precedent mobilised approximately USD 34 billion.
- The current concessional swap facility on FCNR(B) deposits has been running since mid-2026, targeting 3-to-5-year deposits.
- India's forex reserve import cover was around 11 months of imports in mid-2024, the benchmark reference period commonly used for adequacy assessment.
