Monetary policy & the MPC: instruments and transmission

The statutory framework

The Reserve Bank of India Act, 1934, as amended by the Finance Act, 2016, made flexible inflation targeting (FIT) the explicit objective of Indian monetary policy. Section 45ZA empowers the Central Government, in consultation with the RBI, to fix the inflation target once every five years. The notification of 5 August 2016 set the Consumer Price Index (CPI, Combined) target at 4 per cent, with a tolerance band of +/- 2 per cent (i.e. 2-6 per cent). This target was retained for the 2021-2026 period by the notification of 31 March 2021. The headline measure is the CPI (Combined) compiled by the National Statistical Office, not the WPI.

The Monetary Policy Committee

Section 45ZB establishes a six-member Monetary Policy Committee (MPC) that determines the policy repo rate required to achieve the target. Its composition is fixed: three RBI members—the Governor (ex officio Chairperson), the Deputy Governor in charge of monetary policy, and one officer nominated by the Central Board—and three external members appointed by the Central Government for a four-year, non-renewable term. The MPC meets at least four times a year; in practice it meets bi-monthly. Each member has one vote, and in the event of a tie the Governor has a casting (second) vote. Decisions are published with minutes after fourteen days, and the resolution and individual votes are recorded—an accountability device that distinguishes the FIT regime from the pre-2016 discretion of the Governor.

The failure clause

Section 45ZN introduces an enforcement mechanism unique among the world's inflation-targeting regimes. If average inflation breaches the upper or lower tolerance band for three consecutive quarters, the RBI is deemed to have failed and must submit a report to the Central Government explaining the reasons, the remedial actions proposed, and the estimated time to return to target. This first occurred in November 2022, when CPI inflation had stayed above 6 per cent through Q1-Q3 of FY23 (the period from January to September 2022), prompting the RBI to send its first such report.

Why this regime replaced the old one

Before 2016 the RBI pursued a 'multiple-indicator approach' with no single anchor, and the Governor decided rates alone. The Urjit Patel Committee Report (January 2014) recommended CPI-based inflation targeting and a committee structure; the Monetary Policy Framework Agreement of 20 February 2015 between the RBI and the Government operationalised it ahead of the 2016 statutory amendment. Candidates should retain this sequence—Patel Committee (2014) → Framework Agreement (2015) → RBI Act amendment and target notification (2016)—because UPSC frequently tests the chronology and the precise legal provisions (Sections 45ZA, 45ZB, 45ZN) rather than vague description.

The instrument toolkit

The MPC sets the policy repo rate; the operating framework then translates that decision into market interest rates. The instruments fall into rate-based and quantity-based categories.

Repo rate is the rate at which the RBI lends to banks against government securities under the Liquidity Adjustment Facility (LAF). It is the single most important signalling rate. Reverse repo rate is the rate at which the RBI absorbs liquidity; since the introduction of the revised liquidity framework in February 2020 and the Standing Deposit Facility (SDF) in April 2022, the SDF rate (repo minus 25 bps) is the floor of the LAF corridor. The Marginal Standing Facility (MSF) rate (repo plus 25 bps) is the ceiling, against which banks can borrow overnight by dipping into the Statutory Liquidity Ratio up to a permitted limit. The corridor width is thus symmetric at 50 bps around the repo rate, with the Bank Rate aligned to the MSF rate.

Reserve requirements

The Cash Reserve Ratio (CRR), mandated under Section 42 of the RBI Act, is the proportion of Net Demand and Time Liabilities (NDTL) that banks must 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 proportion of NDTL that banks must hold in liquid assets—cash, gold, and approved government securities. CRR is a pure monetary instrument; SLR also serves to channel funds to government borrowing and acts as a prudential buffer.

Open Market Operations and newer tools

Open Market Operations (OMOs) are the outright purchase or sale of government securities to inject or absorb durable liquidity. Operation Twist, deployed by the RBI from December 2019, simultaneously bought long-dated and sold short-dated G-secs to flatten the yield curve without changing the system's net liquidity. The Market Stabilisation Scheme (MSS), introduced in 2004, issues special securities to sterilise large capital inflows. During the COVID-19 period the RBI used Targeted Long-Term Repo Operations (TLTROs) and a Variable Rate Reverse Repo (VRRR) to fine-tune liquidity.

High-yield distinctions

UPSC repeatedly tests the direction of effect: raising CRR, SLR, repo, or selling securities in OMOs is contractionary (reduces money supply); lowering them or buying securities is expansionary. Note also that CRR and repo are RBI instruments, whereas SLR's quantum links to fiscal borrowing. Qualitative (selective) credit controls—margin requirements, moral suasion, and credit rationing—target the direction of credit rather than its aggregate volume, and are distinguished from the quantitative instruments above.

How a rate change reaches the economy

Monetary transmission is the chain by which an MPC decision on the repo rate alters output and inflation. Economists identify several channels. The interest-rate channel works through the cost of borrowing: a repo cut lowers banks' marginal cost of funds, reducing lending rates and stimulating consumption and investment. The credit channel operates through the availability of bank credit and the health of bank balance sheets. The exchange-rate channel runs through capital flows: lower domestic rates can weaken the rupee, aiding exports. The asset-price channel affects wealth via equity and bond valuations, and the expectations channel shapes behaviour through the credibility of the inflation target itself.

Why transmission has been sluggish in India

India's transmission has historically been incomplete and lagged. Banks priced loans on the Base Rate (2010) and then the Marginal Cost of Funds based Lending Rate, MCLR (April 2016), both internal benchmarks that banks could adjust slowly and asymmetrically—passing on hikes faster than cuts. Large reliance on fixed-rate small savings instruments (PPF, NSC), whose rates the Government revises administratively, gives banks a sticky, high-cost deposit base. A high stock of stressed assets in 2015-2018 further blunted the credit channel, as capital-constrained banks were reluctant to lend.

The external benchmark fix

To force faster pass-through, the RBI mandated that from 1 October 2019 all new floating-rate personal, retail, and MSME loans be linked to an external benchmark—most banks chose the repo rate—under the External Benchmark Lending Rate (EBLR) system. Because the benchmark resets automatically, transmission to EBLR-linked loans is now near-immediate, though MCLR-linked corporate loans still lag. The RBI's annual reports document markedly improved pass-through on the EBLR book after 2019.

Exam framing for GS-3

A strong Mains answer distinguishes signalling (the MPC's rate decision and stance) from operating (managing the weighted average call rate near the repo through LAF) and from transmission (the actual movement of bank lending and deposit rates). It links sluggish transmission to specific causes—internal benchmarks, small-savings stickiness, banking-sector stress—and to specific remedies (EBLR, the SDF, liquidity management). Retain the dated sequence of lending-rate regimes: Prime Lending Rate → Base Rate (2010) → MCLR (April 2016) → EBLR (October 2019). For Prelims, remember that the call money rate is the overnight interbank rate the RBI steers, and that a 'neutral' stance signals no directional bias on the next move, while 'withdrawal of accommodation' signals a tightening path.
