FCNR flows to complicate liquidity management, lead RBI to deploy more tools: Economists

The surge in Foreign Currency Non-Resident (Bank) or FCNR(B) deposits has emerged as a significant challenge for the Reserve Bank of India's liquidity management framework, pushing banking system surplus liquidity to a four-year high. To understand this development, we must first revisit the origins of the FCNR(B) scheme. Introduced in 1993 as a replacement for the earlier FCNR(A) scheme, FCNR(B) allows non-resident Indians (NRIs) and Persons of Indian Origin (PIOs) to maintain term deposits in designated foreign currencies — primarily US dollars, British pounds, euros, Canadian dollars, Australian dollars, and Japanese yen — with authorized dealer banks in India. The critical feature is that the exchange rate risk is borne by the bank, not the depositor, with the RBI providing a swap window to hedge this risk. The current spike in FCNR(B) inflows is largely driven by the interest rate differential between India and advanced economies. While the US Federal Reserve maintained rates at 5.25-5.50% until its September 2024 cut, India's policy repo rate has remained at 6.50% since February 2023. However, the forward premium on dollar-rupee swaps has made hedged returns on FCNR(B) deposits highly attractive for NRIs, often yielding 7-8% annualized — significantly higher than domestic rupee deposit rates. This has triggered massive capital inflows, with FCNR(B) deposits rising by over $10 billion in the first half of FY25 alone. When these dollar inflows enter the banking system, banks surrender the foreign currency to the RBI in exchange for rupees, expanding the central bank's balance sheet and injecting rupee liquidity. The RBI then faces a classic 'impossible trinity' dilemma: maintaining exchange rate stability, monetary policy autonomy, and free capital mobility simultaneously. To sterilize this liquidity injection — i.e., prevent it from fuelling inflation or asset bubbles — the RBI must absorb the surplus rupees. Traditionally, this is done through Open Market Operations (OMOs), specifically selling government securities, or via the Liquidity Adjustment Facility (LAF) using variable rate reverse repo (VRRR) auctions. However, with excess liquidity now at a four-year high — averaging over ₹1.5 lakh crore daily in the LAF window — the RBI's conventional tools are stretched. This is where the prospect of incremental Cash Reserve Ratio (CRR) hikes enters the picture. Under Section 42(1) of the RBI Act, 1934, the central bank can mandate banks to maintain a certain percentage of their Net Demand and Time Liabilities (NDTL) as reserves with it. An incremental CRR — applied only on the increase in deposits above a baseline — was last used in August 2023 when the RBI imposed a 10% incremental CRR on the increase in NDTL between May 19 and July 28, 2023, to absorb liquidity from the withdrawal of ₹2000 notes. A repeat of this measure would signal the RBI's discomfort with persistent surplus liquidity. The significance of this situation extends beyond technical central banking. Record forex reserves of $729.3 billion (as of late September 2024) provide a formidable buffer against external shocks, covering over 11 months of imports — a stark contrast to the 1991 crisis when reserves barely covered three weeks of imports. This reserve adequacy enhances India's sovereign credit profile, supports the rupee, and gives the RBI policy space. However, the sterilization cost is substantial: the RBI earns lower returns on its foreign assets (US Treasuries yielding ~4%) while paying higher rates on its rupee liabilities (reverse repo at 3.35%, VRRR at ~6.5%), creating a negative carry that impacts its surplus transfer to the government under Section 47 of the RBI Act. Looking ahead, the RBI's toolkit may expand further. The Standing Deposit Facility (SDF), introduced in April 2022 under Section 17(4A) of the RBI Act, allows banks to park excess liquidity without collateral at the SDF rate (currently 6.25%), serving as the floor of the LAF corridor. Increased VRRR auctions with longer tenors (14-day, 28-day) are likely. The RBI may also consider Open Market Sale of Government Securities (OMO sales) or Special OMOs (Operation Twist) to manage yield curves. Crucially, the Monetary Policy Committee (MPC), constituted under Section 45ZB of the RBI Act, must balance liquidity management with its primary mandate of inflation targeting (4% ± 2%). Persistent surplus liquidity could transmit into excessive credit growth, asset price inflation, or currency appreciation pressures — all of which complicate the inflation-growth trade-off. For competitive exam aspirants, this episode encapsulates key themes: monetary policy transmission, sterilization operations, capital flow management, the impossible trinity, central bank balance sheet dynamics, and the institutional framework governing RBI's operations under the RBI Act, 1934, and the Banking Regulation Act, 1949. It also connects to broader governance questions about central bank independence, fiscal-monetary coordination, and India's integration with global financial markets.
