RBI's liquidity test may set future course

The Reserve Bank of India (RBI) finds itself at a critical juncture in liquidity management, navigating a significant surplus primarily fueled by robust inflows under the Foreign Currency Non-Resident (Bank) or FCNR(B) scheme. This development is not merely a technical adjustment in monetary operations but a reflection of deeper structural shifts in India's external sector and capital flows. To understand the gravity of the current situation, we must first appreciate the historical context. The FCNR(B) scheme, reintroduced in September 2013 during the 'taper tantrum' crisis when the rupee depreciated sharply, was a strategic masterstroke by then-Governor Raghuram Rajan. It allowed Non-Resident Indians (NRIs) to deposit foreign currency (primarily USD) in Indian banks with the exchange rate risk borne by the RBI through a swap window. This effectively insulated banks from currency volatility and mobilized over $34 billion in 2013 alone, stabilizing the rupee and shoring up reserves. Fast forward to 2024, the scheme is witnessing a resurgence. With the US Federal Reserve maintaining higher interest rates for longer, the interest rate differential between USD deposits and domestic rupee deposits has widened, making FCNR(B) deposits highly attractive for NRIs. Furthermore, the inclusion of Indian government bonds in the JPMorgan Government Bond Index-Emerging Markets (GBI-EM) starting June 2024 has triggered passive foreign portfolio inflows. Coupled with strong FDI and remittance flows, the banking system is awash with liquidity. As of late May 2024, the banking system liquidity surplus averaged over Rs 1.5 lakh crore, prompting the RBI to act. The key stakeholders here are the RBI, commercial banks, NRIs, and the Government of India. The RBI, under the RBI Act, 1934 (specifically Section 17 governing its business operations and Section 45W for credit control), is mandated to maintain price stability while keeping in mind the objective of growth. The current surplus, if unmanaged, risks pushing the weighted average call rate (WACR) below the policy repo rate (currently 6.5%), distorting the monetary policy transmission mechanism. Commercial banks, flush with funds, face compressed net interest margins (NIMs) as they struggle to deploy funds at viable yields. NRIs benefit from a risk-free, high-yield avenue backed by a sovereign swap guarantee. The Government, meanwhile, benefits from lower borrowing costs but must coordinate with the RBI on fiscal-monetary alignment. The RBI's tool of choice — the Variable Rate Reverse Repo (VRRR) auction — is a fine-tuning instrument under the Liquidity Adjustment Facility (LAF). Unlike fixed-rate reverse repos, VRRR allows the RBI to discover the market-clearing rate for absorbing liquidity, signaling its comfort level with short-term rates. The recent 14-day VRRR auction (conducted in late May 2024) saw robust participation, with cut-off rates hovering near the repo rate, indicating that the RBI is successfully anchoring the operating target. However, VRRR is a temporary measure; it only parks funds for a fortnight. For durable liquidity absorption, the RBI may resort to Open Market Operations (OMO) — outright sale of government securities under Section 17(8) of the RBI Act — or dollar-rupee sell/buy swaps. The latter is particularly elegant: it sucks out rupee liquidity while simultaneously building forex reserves, killing two birds with one stone. The significance for India is multifold. First, effective liquidity management ensures that the monetary policy stance — currently 'withdrawal of accommodation' — transmits effectively to bank lending rates, curbing inflationary pressures. Second, managing FCNR(B) inflows prevents excessive rupee appreciation, protecting export competitiveness — a key concern for the 'Make in India' and 'Atmanirbhar Bharat' visions. Third, the RBI's ability to provide swap cover on FCNR(B) deposits showcases the strength of India's forex reserves (over $645 billion as of May 2024), enhancing macroeconomic credibility. Constitutionally, while the RBI operates autonomously in monetary policy under the RBI Act (amended in 2016 to establish the Monetary Policy Framework Agreement with the Government), its actions have direct implications for fiscal management under Article 112 (Annual Financial Statement) and Article 280 (Finance Commission recommendations on resource distribution). Looking ahead, the trajectory of US Fed rate cuts, the pace of index-related bond inflows, and the sustainability of FCNR(B) deposits will dictate the RBI's playbook. If the Fed cuts rates in late 2024, the interest arbitrage may narrow, slowing FCNR(B) inflows. The RBI may then shift from absorption to injection mode. Aspirants must track the Monetary Policy Committee (MPC) minutes, RBI's monthly bulletin, and the Quarterly Report on Management of Foreign Exchange Reserves.
