Money, banking & the RBI (monetary policy)

The RBI: mandate and architecture

The Reserve Bank of India was established under the Reserve Bank of India Act, 1934 and commenced operations on 1 April 1935. Originally a privately owned shareholders' bank, it was nationalised on 1 January 1949 under the Reserve Bank (Transfer to Public Ownership) Act, 1948. Its preamble was amended in 2016 to give statutory force to its core objective. The RBI functions as the monetary authority, the issuer of currency (under the minimum reserve system since 1956, requiring gold and foreign securities of not less than Rs 200 crore), the banker to the government and to banks, the regulator of the banking and payment systems, and the manager of foreign exchange under the Foreign Exchange Management Act (FEMA), 1999.

The 2016 inflation-targeting framework

The defining reform is the flexible inflation targeting (FIT) regime. Following the recommendations of the Urjit Patel Committee (2014), the government and RBI signed a Monetary Policy Framework Agreement on 20 February 2015, and Parliament amended the RBI Act in 2016 to insert Section 45ZA onwards. The central government, in consultation with the RBI, notifies the inflation target every five years. The target set on 5 August 2016 and retained on 31 March 2021 (to March 2026) is 4% CPI (Consumer Price Index, Combined) inflation, with a tolerance band of +/- 2% (i.e., 2% to 6%).

A failure to maintain the target is defined as the average CPI inflation breaching the band for three consecutive quarters. On such failure the RBI must submit a report to the central government explaining the reasons, the remedial actions, and the estimated time to return to target. The first such failure report was submitted in November 2022, after inflation stayed above 6% through three quarters of 2022 amid the Ukraine-war commodity shock.

The Monetary Policy Committee

The Monetary Policy Committee (MPC), created under Section 45ZB, has six members: the RBI Governor (chairperson), the Deputy Governor in charge of monetary policy, one RBI officer nominated by the Central Board, and three external members appointed by the central government for a four-year non-renewable term. Decisions are by majority vote; in a tie the Governor has a casting vote. The MPC meets at least four times a year and a quorum is four members. The committee sets the policy repo rate to achieve the inflation target. This statutory, committee-based decision-making replaced the earlier system in which the Governor alone set rates, embedding accountability and reducing discretion.

Quantitative instruments

The RBI steers liquidity and the cost of money through several levers. The repo rate is the rate at which the RBI lends to commercial banks against government securities under the Liquidity Adjustment Facility (LAF); it is the principal policy rate. The reverse repo and, since its operationalisation on 8 April 2022, the Standing Deposit Facility (SDF) absorb liquidity. Since the corridor reform, the SDF forms the floor and the Marginal Standing Facility (MSF) the ceiling, with the repo rate at the centre of the LAF corridor.

The Cash Reserve Ratio (CRR), under Section 42 of the RBI Act, is the share of net demand and time liabilities (NDTL) that banks keep as cash with the RBI; it earns no interest. The Statutory Liquidity Ratio (SLR), under Section 24 of the Banking Regulation Act, 1949, is the share of NDTL held in cash, gold, or approved (mostly government) securities. The RBI also uses Open Market Operations (OMOs)—the outright purchase or sale of government securities—and the Market Stabilisation Scheme (MSS), introduced in 2004, to manage durable liquidity.

Transmission and the external linkage

Monetary transmission—the pass-through of policy rate changes to bank lending rates—was historically weak. The RBI mandated the Marginal Cost of Funds based Lending Rate (MCLR) from 1 April 2016, and from 1 October 2019 required banks to link new floating-rate retail and MSME loans to an external benchmark (typically the repo rate), sharpening transmission.

The qualitative dimension

Beyond rates, the RBI deploys selective credit controls, moral suasion, and margin requirements, and regulates the Priority Sector Lending (PSL) norms (40% of adjusted net bank credit for domestic commercial banks). It is also the regulator of payment systems under the Payment and Settlement Systems Act, 2007, and launched the pilot of the Digital Rupee (e-Rupee / CBDC) in the wholesale segment on 1 November 2022 and retail on 1 December 2022.

Why this matters for the exam

This topic is among the most heavily tested areas of GS-3 and Prelims. In Prelims, UPSC repeatedly probes precise definitions—the 2019 PYQ on what an increase in the bank's repo rate by the RBI does, and the 2017 PYQ on what 'liquidity' the RBI seeks to control. You must distinguish CRR (cash, no interest) from SLR (cash/gold/securities, with returns), and know which instruments inject versus absorb liquidity. In Mains GS-3, expect analytical questions on inflation targeting, monetary-fiscal coordination, transmission, and the trade-off between growth and price stability. Retain the 4% +/- 2% band, the six-member MPC composition, and the three-consecutive-quarter failure rule—these are recurring high-yield facts.
