Functions of the Reserve Bank of India: Role, Structure and Tools for RBI Grade B Finance

Last updated: 2026-11-13 · MockMentor

"Functions of Reserve Bank of India" is a separate line in the Financial System unit of the RBI Grade B Phase 2 Finance syllabus, and for an exam conducted by RBI itself it is never skipped. Objective questions test sections of the RBI Act, the names of departments and subsidiaries, and the tools of monetary policy. Descriptive questions ask how RBI balances its many roles, or how a particular function such as supervision or the Retail Direct scheme has changed. This chapter covers RBI's history, structure and every major function.

In one line: RBI is India's central bank: it sets monetary policy to keep inflation near 4%, issues currency, regulates and supervises banks and NBFCs, manages the forex reserves and the government's borrowing, runs the payment systems and protects customers.

Basic concepts

• Central bank: the apex monetary authority of a country, which issues currency, manages money and credit, and acts as the lender of last resort to banks.
• Lender of last resort: the role of the central bank in lending to solvent but illiquid banks during a crisis, to prevent panic from spreading.
• Banker to the government: the central bank keeps the government's accounts, makes and receives its payments and manages its borrowing.
• Banker's bank: banks keep accounts with the central bank, hold their cash reserves there and settle payments with one another through it.
• Prudential regulation: rules on capital, liquidity, exposure and asset quality that keep banks safe.
• Minimum Reserve System: the rule under which RBI must hold at least ₹200 crore of gold and foreign assets, of which at least ₹115 crore must be gold, to back the currency it issues.

Why in News?

1. In October 2026, the six-member Monetary Policy Committee (MPC) raised the repo rate by 25 basis points to 5.50% and shifted to a stance of "calibrated tightening", with CPI inflation projected at 5.2% for 2026-27.
2. RBI issued final directions on the expected credit loss (ECL) framework in July 2026 and on capital for credit risk under the Basel III standardised approach in April 2026; both take effect on 1 April 2027.
3. RBI's Financial Inclusion Index stood at 70.0 for the year ended March 2026.
4. RBI has continued to issue consolidated "Master Directions" for each type of regulated entity, replacing hundreds of older circulars with a smaller set of function-wise rules.

History and evolution

The first Governor was Sir Osborne Smith, and the first Indian Governor was C. D. Deshmukh. Sanjay Malhotra became the 26th Governor in December 2024.

Organisation and governance

Central Board of Directors

RBI is governed by a Central Board of Directors, appointed by the Government of India under Section 8 of the RBI Act. It has:

• Official directors: the Governor and up to four Deputy Governors, appointed for up to five years.
• Non-official directors: ten directors nominated by the government from various fields, four directors from the four Local Boards, and two government officials.

The Board meets at least six times a year. It has committees such as the Committee of the Central Board, the Board for Financial Supervision and the Board for Regulation and Supervision of Payment and Settlement Systems. Four Local Boards (Mumbai, Kolkata, Chennai and New Delhi) advise on regional matters.

Departments and offices

RBI works through central office departments such as Monetary Policy, Regulation, Supervision, Currency Management, Foreign Exchange, Financial Markets Operations, Government and Bank Accounts, Payment and Settlement Systems, Consumer Education and Protection, and Economic and Policy Research. It has regional offices in most state capitals.

Subsidiaries

RBI also funds and supports training institutions such as the College of Agricultural Banking in Pune and the Indira Gandhi Institute of Development Research in Mumbai.

Important provisions of the RBI Act, 1934

Function 1: Monetary authority

RBI's primary objective, as stated in the preamble to the RBI Act after its amendment in 2016, is to maintain price stability while keeping in mind the objective of growth.

Inflation targeting and the MPC

• The government sets the inflation target in consultation with RBI. The current target is 4% inflation measured by the Consumer Price Index (CPI), with a tolerance band of 2% to 6%.
• If inflation stays outside the band for three consecutive quarters, RBI must send a report to the government explaining why and what it will do.
• The MPC has six members: the Governor (chair, with a casting vote), the Deputy Governor in charge of monetary policy, one RBI officer nominated by the Board, and three external members appointed by the government for four years. A quorum is four members, and the committee meets at least four times a year, in practice six.

Instruments of monetary policy

The weighted average call rate is the operating target: RBI uses liquidity tools to keep it close to the repo rate. Qualitative tools, such as margin requirements on loans against particular goods, moral suasion and selective credit controls, are used less often than in the past. The monetary policy chapter in ESI explains transmission and the evolution of policy since 1991.

Function 2: Issuer of currency

• RBI has the sole right to issue bank notes under Section 22. The government issues coins and the one rupee note, which RBI puts into circulation.
• RBI decides, with the government, how many notes of each denomination are needed, and has them printed at four presses: two owned by the government's Security Printing and Minting Corporation of India (Nashik and Dewas) and two by BRBNMPL (Mysuru and Salboni).
• Currency chests, run mainly by banks, store notes and coins for distribution.
• The Clean Note Policy aims to keep good-quality notes in circulation and withdraw soiled ones.
• Since 1957, RBI follows the Minimum Reserve System for backing currency.
• RBI withdrew the ₹2,000 note from circulation in May 2023, though it remains legal tender.
• The digital rupee, or e-rupee, is a Central Bank Digital Currency (CBDC). Pilots began in the wholesale segment in November 2022 and in the retail segment in December 2022.

Function 3: Banker to the government

• RBI keeps the accounts of the central government and, by agreement, of state governments, and receives and pays money on their behalf through agency banks.
• Ways and Means Advances (WMA) are short-term loans to cover temporary gaps between receipts and payments. If the government draws beyond the limit, it is an overdraft and carries a higher rate.
• RBI cannot buy government bonds directly at auction (primary market) except in special cases, after the agreement of 1997 ended automatic monetisation through ad hoc treasury bills and the FRBM Act of 2003 barred it.

Public debt management

RBI manages the market borrowing of the central government and the states. It:

• Announces the borrowing calendar in consultation with the government.
• Conducts auctions of dated securities, treasury bills and State Development Loans (SDLs) on its E-Kuber platform.
• Uses the Primary Dealer system to ensure that auctions are fully subscribed.
• Opened the government securities market to individuals through RBI Retail Direct in November 2021, which lets a person open a Retail Direct Gilt account and invest online.

An independent Public Debt Management Agency has long been proposed but has not been set up.

Function 4: Banker to banks

• Banks keep current accounts with RBI to hold their CRR balances and settle payments with one another.
• RBI is the lender of last resort, and it has used special liquidity windows during crises such as 2008 and 2020.
• It runs the settlement of interbank payments through RTGS and the clearing of government securities through the Negotiated Dealing System-Order Matching (NDS-OM).

Function 5: Regulator of the banking and financial system

RBI regulates commercial banks, small finance banks, payments banks, regional rural banks, cooperative banks, NBFCs, housing finance companies, all-India financial institutions, credit information companies and asset reconstruction companies.

Main areas of regulation

1. Licensing: new banks and branches, entry of foreign banks, and the "fit and proper" status of promoters.
2. Capital adequacy: Basel III capital rules, with a minimum total capital of 9% of risk-weighted assets plus a capital conservation buffer of 2.5%.
3. Asset classification and provisioning: a loan becomes a non-performing asset (NPA) if interest or principal is overdue for more than 90 days; the ECL framework will replace incurred-loss provisioning from April 2027.
4. Liquidity: Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR).
5. Exposure norms: limits on lending to a single borrower or group under the Large Exposures Framework.
6. Priority sector lending: 40% of adjusted net bank credit for domestic commercial banks, with sub-targets for agriculture, micro enterprises and weaker sections.
7. Corporate governance: tenure of chief executives, board composition and compensation.
8. Customer service and fair practice codes.

Regulation of NBFCs and cooperative banks

NBFCs are regulated under a scale-based framework introduced in 2021, which places them in four layers (base, middle, upper and top) with stricter rules for larger and more interconnected firms. Urban cooperative banks are placed in four tiers by deposit size. After the 2020 amendment, RBI has powers over the management and audit of cooperative banks, which ended much of the old "dual control" with state Registrars of Cooperative Societies.

Function 6: Supervisor

Supervision checks that the rules are followed and that banks are sound. The Board for Financial Supervision, set up in 1994 and chaired by the Governor, oversees this work.

• On-site inspection: RBI moved from the CAMELS approach (Capital, Asset quality, Management, Earnings, Liquidity, Systems) to Risk-Based Supervision (RBS) through the SPARC model (Supervisory Program for Assessment of Risk and Capital) from 2013 onwards.
• Off-site monitoring: banks send regular returns, analysed through early warning systems.
• Prompt Corrective Action (PCA): banks that breach thresholds for capital, asset quality or leverage face restrictions on lending, dividends and expansion until they recover. Similar frameworks exist for NBFCs and urban cooperative banks.
• Unified supervision: in 2019 RBI merged the separate supervision departments for banks, cooperative banks and NBFCs into one Department of Supervision.
• Enforcement: RBI imposes monetary penalties, restrictions on business and, in serious cases, supersedes the board of a bank or places it under moratorium.

Function 7: Manager of foreign exchange

• RBI administers the Foreign Exchange Management Act (FEMA), 1999, which treats foreign exchange violations as civil offences.
• It licenses Authorised Dealers (mostly banks) and money changers.
• It holds and manages India's foreign exchange reserves, which were around US$ 720 billion in late October 2026. Reserves consist of foreign currency assets, gold, Special Drawing Rights (SDRs) and the reserve position in the International Monetary Fund (IMF).
• It intervenes in the forex market to smooth sharp swings in the rupee. RBI does not target any particular exchange rate.
• It sets limits for schemes such as the Liberalised Remittance Scheme (LRS), under which a resident individual can send up to US$ 250,000 abroad each financial year.

Function 8: Regulator of payment and settlement systems

Under the Payment and Settlement Systems Act, 2007, RBI authorises and oversees payment systems. It owns and runs RTGS and NEFT, which are available 24 hours a day on all days. It has promoted the National Payments Corporation of India (NPCI), which runs UPI, IMPS, RuPay, the National Automated Clearing House (NACH) and other retail systems. The Board for Regulation and Supervision of Payment and Settlement Systems (BPSS) oversees this area. RBI's Payments Vision documents set out goals for safety, efficiency and inclusion.

Function 9: Developmental role

RBI has always done more than a typical central bank. It helped build institutions for agricultural, industrial, export and housing finance, and it continues to:

• Set priority sector targets and promote financial inclusion through the business correspondent model and the National Strategy for Financial Inclusion.
• Run financial literacy programmes such as Financial Literacy Week and Centres for Financial Literacy.
• Promote innovation through the Regulatory Sandbox and the Reserve Bank Innovation Hub.
• Develop financial markets: the money market, government securities market, interest rate and foreign exchange derivatives, and the rupee interest rate benchmarks.

Function 10: Consumer protection

• The Reserve Bank Integrated Ombudsman Scheme, 2021 brought the earlier separate schemes for banks, NBFCs and digital transactions under one scheme with a "one nation, one ombudsman" approach. Complaints are filed through the Complaint Management System portal.
• The Charter of Customer Rights (2014) sets out five rights: fair treatment, transparency, suitability, privacy and grievance redress.
• RBI limits customer liability in unauthorised electronic transactions if the customer reports them quickly.
• The "RBI Kehta Hai" campaign spreads awareness of safe banking.

Function 11: Financial stability

RBI watches the system for risks that could spread across institutions. It:

• Publishes the Financial Stability Report twice a year, with stress tests of banks and NBFCs.
• Identifies Domestic Systemically Important Banks (D-SIBs), currently SBI, HDFC Bank and ICICI Bank, which must hold additional capital.
• Uses macroprudential tools such as higher risk weights for particular sectors, as it did for unsecured consumer credit in November 2023.
• Works with other regulators through the FSDC sub-committee, which the Governor chairs.

Function 12: Research, statistics and publications

RBI collects data and publishes research that guides policy and public debate.

RBI also runs surveys such as the Consumer Confidence Survey, the Inflation Expectations Survey of Households, the Industrial Outlook Survey and the Survey of Professional Forecasters.

RBI's income and surplus transfer

RBI earns income mainly from interest on its holdings of government securities and foreign assets, gains on foreign exchange sales and its liquidity operations. After meeting expenses and setting aside money for its Contingency Risk Buffer (CRB), it transfers the surplus to the government under Section 47. The Bimal Jalan Committee (2019) set the Economic Capital Framework, which RBI reviewed in 2025 and under which the CRB is kept between 4.5% and 7.5% of the balance sheet. RBI's accounting year was changed to April to March from 2020-21, matching the government's.

RBI's balance sheet

RBI's balance sheet shows how its functions fit together. Its main items are:

When RBI buys dollars, foreign assets rise on one side and bank reserves or currency rise on the other. When it buys government bonds through OMOs, its rupee securities rise and so does liquidity. The revaluation accounts absorb gains and losses from changes in exchange rates and gold prices, which are not counted as income until realised.

The monetary transmission mechanism

A change in the repo rate reaches the economy through several channels.

Transmission is faster for loans linked to external benchmarks and to money market and bond rates, and slower for deposits and MCLR-linked loans. Small savings rates set by the government, the share of fixed-rate deposits and competition for deposits also affect transmission.

Review of the inflation targeting framework

The inflation target is set for five years at a time. The first two periods ran from 2016 to 2021 and from April 2021 to March 2026. Before the second period ended, RBI released a discussion paper in 2025 on questions such as whether to target headline or core inflation, whether 4% is still the right number, and whether the 2% to 6% band should change. In March 2026, the government notified that the target stays at 4%, with the band of 2% to 6%, for April 2026 to March 2031. Supporters of the framework point to lower and more stable inflation since 2016, apart from the supply shocks of 2020 to 2022.

Important committees on RBI and monetary policy

RBI's role in cooperative banks

Cooperative banks have long been the weakest part of Indian banking because of "dual control": RBI regulated banking functions, while state Registrars of Cooperative Societies controlled management, elections and audit. After several failures, including PMC Bank in 2019, the Banking Regulation (Amendment) Act, 2020 gave RBI powers to:

• Supersede the board of a cooperative bank.
• Approve the appointment of chief executives and set qualifications for directors.
• Order audits and require prior approval for some capital raising.
• Prepare schemes of reconstruction or amalgamation without first placing a moratorium.

RBI also introduced a four-tier regulatory framework for urban cooperative banks by deposit size in 2022, an umbrella organisation (the National Urban Cooperative Finance and Development Corporation) for the sector, and the Prompt Corrective Action style Supervisory Action Framework for weak UCBs.

Monetary aggregates

RBI publishes measures of money supply, which show how much money is available in the economy.

M0 is also called high-powered money, because banks can create a multiple of it as credit. The money multiplier is M3 ÷ M0. M3 is the main measure of money supply used in analysis.

RBI's international role

• RBI represents India at the Bank for International Settlements, the Financial Stability Board and the Basel Committee.
• It manages India's relationship with the IMF on the operational side, including the reserve tranche and SDR holdings.
• It has currency swap arrangements with other central banks, such as the bilateral swap line with Japan and the SAARC currency swap framework, under which RBI can lend to central banks of neighbouring countries.
• It works on cross-border payment links and rupee internationalisation.

Autonomy and accountability

RBI's independence is a frequent descriptive and interview topic. Its autonomy rests on the fixed tenure of the Governor, the statutory MPC and its control over its own balance sheet. At the same time, Section 7 lets the government issue directions, and the government appoints the Governor, Deputy Governors and most directors. Disagreements over surplus transfers, liquidity for NBFCs and the PCA framework in 2018 showed the tension. Most experts favour operational independence for RBI with clear accountability through the inflation target, published minutes and reports to Parliament.

Challenges

• Balancing price stability against growth and financial stability, especially when global shocks push up food and fuel prices.
• Weak transmission of policy rates to loan and deposit rates in some periods.
• Conflict between its role as debt manager for the government, which wants low yields, and its role as monetary authority.
• Supervising a growing number of NBFCs, fintech firms and digital lenders, along with cooperative banks with weak governance.
• Cyber security, digital fraud and the spread of crypto assets and stablecoins.
• Managing volatile capital flows and the rupee without losing reserves.

Way forward

1. Keep inflation expectations anchored through clear communication and a credible target.
2. Strengthen supervision with data analytics and supervisory technology (SupTech), and bring forward risk-based supervision for NBFCs and cooperative banks.
3. Move debt management to a separate agency in time, to remove conflicts of interest.
4. Implement ECL provisioning and the revised Basel III rules smoothly from April 2027.
5. Expand the e-rupee carefully while protecting privacy and bank deposits.
6. Build skills and cooperation with other regulators to handle climate risk and cross-border payments.

Possible exam and interview questions

1. Discuss the functions of the Reserve Bank of India. How has its role changed since the adoption of flexible inflation targeting in 2016? (620 words)
2. Explain how RBI supervises banks. What is the role of Risk-Based Supervision and Prompt Corrective Action? (420 words)
3. Distinguish between the Standing Deposit Facility and the Marginal Standing Facility. Why did RBI introduce the SDF in 2022?
4. "RBI's role as debt manager conflicts with its role as monetary authority." Do you agree?
5. Interview: How independent should a central bank be from the government?
