The RBI and How Monetary Policy Works

The Reserve Bank of India is the central bank. It manages the currency, the banking system, and the cost of money in the economy. For Prelims, focus on what it does and the tools it uses, not on memorising whatever the current repo rate happens to be, that number changes with every MPC meeting.

Where the RBI gets its income

The RBI earns mainly from:

• Returns on its holdings of government securities.
• Returns on its foreign currency assets held abroad.

It does not lend directly to private companies. Its lending is to banks and the government. This is a common exam trap.

The RBI's roles beyond monetary policy

Monetary policy is only one of the RBI's functions. The others are just as testable:

• Banker to the Government: manages the Government's accounts and public debt.
• Banker's bank: holds banks' reserves and acts as the settlement authority between them.
• Lender of last resort: provides emergency liquidity to banks facing a crisis, when no one else will.
• Sole note-issuing authority: the RBI has the sole right to issue currency notes in India, with one specific exception.

The one-rupee-note trap

The one-rupee note and coins are issued by the Government of India (via the Ministry of Finance), not the RBI, and carry the signature of the Finance Secretary, not the RBI Governor. All other denominations of currency notes are issued by the RBI and carry the Governor's signature. This one exception is UPSC's favourite way to test whether "the RBI issues all currency" is stated as an absolute (wrong) or a near-absolute with the correct carve-out.

How the RBI came to be

The RBI was not born as a government department. It was constituted under the Reserve Bank of India Act, 1934, on the recommendation of the Hilton Young Commission (the Royal Commission on Indian Currency and Finance, 1926), and it commenced operations on 1 April 1935 as a shareholders' bank, its capital held by private shareholders, not the state. That changed after independence: the Reserve Bank of India (Transfer to Public Ownership) Act, 1948 nationalised it with effect from 1 January 1949, ending private ownership and bringing the RBI fully under Government of India control. Keep that date distinct from a much later, unrelated event UPSC likes to pair it with: the nationalisation of 14 major commercial banks came two decades afterward, in 1969 (a further 6 followed in 1980), a different set of institutions nationalised for a different reason. The RBI's own 1949 nationalisation is not the same event, and predates it by twenty years.

The Central Board: who actually sits on it

Governance sits with the Central Board of Directors, whose composition is fixed by Section 8 of the RBI Act, 1934, worth knowing precisely because UPSC has tested its exact make-up:

• The Governor and up to four Deputy Governors, appointed by the Central Government, the RBI's own full-time executive.
• Four directors, one nominated by the Central Government from each of the RBI's four Local Boards (at Mumbai, Kolkata, Chennai and New Delhi, representing the western, eastern, southern and northern regions respectively), which themselves advise the Central Board on regional and cooperative/indigenous banking matters.
• Ten directors nominated by the Central Government from various fields, trade, industry and agriculture among them, each serving a four-year term, renewable once (a maximum of two terms, eight years).
• One government official, nominated by the Central Government, typically from the Ministry of Finance.

The Governor chairs the Board and is the RBI's chief executive. Deputy Governors and the nominated government official may attend Board meetings and take part in discussion but do not ordinarily vote, a detail that trips up a statement question assuming every Board member votes on equal footing.

Quantitative tools

These affect the overall volume of money and credit in the system:

• Repo rate: the rate at which banks borrow from the RBI. Raising it makes borrowing costlier and cools inflation.
• Reverse repo rate: the rate at which the RBI borrows from banks.
• Cash Reserve Ratio (CRR): the share of deposits banks must keep with the RBI.
• Statutory Liquidity Ratio (SLR): the share banks must hold in safe assets like government securities.
• Open Market Operations (OMO): buying or selling government securities to manage liquidity.

Qualitative (selective) tools

These target where credit flows rather than its total volume:

• Margin requirements: raising the minimum margin on loans against specific collateral (e.g. shares) to curb speculative lending in that sector without touching credit everywhere else.
• Moral suasion: the RBI persuading banks informally, through meetings and letters, to follow a certain lending direction, with no legal compulsion.
• Direct action: formal penalties or restrictions the RBI can impose on a bank that does not comply with its directions.

The quantitative-vs-qualitative split itself is a testable distinction: CRR, SLR, repo, and OMO change the total pool of credit; margin requirements and moral suasion change which sectors get it.

Beyond repo and CRR: the RBI's newer liquidity tools

The repo, reverse repo, CRR, SLR and OMO toolkit above is the classical list, but the RBI's actual day-to-day liquidity corridor has moved on since, and this is exactly the kind of update an older note misses.

Since 8 April 2022, the floor of the RBI's Liquidity Adjustment Facility (LAF) corridor is no longer the fixed reverse repo rate, it is the Standing Deposit Facility (SDF). Under the SDF, banks park surplus funds with the RBI overnight without pledging any government securities as collateral, unlike a reverse repo, which needs collateral to move. The SDF rate sits 25 basis points below the repo rate. At the ceiling sits the Marginal Standing Facility (MSF), in place since 9 May 2011, an emergency overnight window letting scheduled banks borrow against government securities, including by dipping into their SLR holdings, once they have exhausted other funding routes; its rate sits 25 basis points above the repo rate. Together, SDF and MSF form a symmetric corridor 50 basis points wide, with the repo rate at its centre. Note precisely what changed and what didn't: reverse repo as an instrument still exists exactly as described above, but it is the SDF, not a fixed reverse repo rate, that now defines the corridor's floor, the single most commonly outdated fact in older monetary policy material.

Two further tools address a specific transmission problem: a repo rate cut taking too long to reach the interest rate an actual borrower pays. Long Term Repo Operations (LTRO), introduced in February 2020, lend banks funds for one to three years at the prevailing repo rate against government securities, considerably longer money than an ordinary overnight repo, meant to encourage banks to lend at similarly durable, similarly low rates rather than just parking cheap short-term funds. Targeted Long Term Repo Operations (TLTRO), launched the following month, went a step further: banks drawing TLTRO funds must deploy them, within a set window, into specific instruments such as investment-grade corporate bonds, commercial paper and debentures, aiming the liquidity straight at market segments under stress instead of leaving banks free to simply hold it. A later round, TLTRO 2.0, earmarked funds specifically for small and mid-sized NBFCs and microfinance institutions, entities that don't borrow in the bond market directly and were among the most credit-starved once the pandemic hit.

Operation Twist, run from December 2019, is a variant of Open Market Operations rather than a separate instrument: the RBI simultaneously buys long-tenure government securities and sells short-tenure ones of a roughly matching amount. Because the purchase and sale are broadly liquidity-neutral, the operation does not flood the system with fresh money the way a plain OMO purchase would; instead it "twists" the yield curve, pulling long-term yields down (cheapening long-term borrowing to encourage investment) while short-term rates stay comparatively steady.

The MPC

The Monetary Policy Committee sets the repo rate to keep retail inflation within a target band. It has six members, three from the RBI (including the Governor, who chairs it) and three external members appointed by the Government, and meets at least four times a year. Decisions are by majority vote; the Governor holds a casting vote in case of a tie.

The inflation target

Under the flexible inflation targeting framework (in force since 2016), the RBI's mandate is to keep CPI (Consumer Price Index) inflation at 4%, with a tolerance band of +/-2%, so anywhere from 2% to 6% is considered "on target." If inflation stays outside this band for three consecutive quarters, the RBI must explain why to the Government and set out a plan to bring it back, a built-in accountability mechanism, not just a target on paper.

The RBI and India's foreign exchange law

Foreign exchange in India was originally governed by the Foreign Exchange Regulation Act (FERA), 1973, a control-era law under which a violation was a criminal offence. Liberalisation needed a different instrument: the Foreign Exchange Management Act (FEMA), 1999 replaced FERA with effect from 1 June 2000, reframing violations as civil offences carrying monetary penalties, in keeping with an economy opening up rather than one being policed shut. FEMA gives the RBI the lead regulatory role: it issues the regulations and directions that give FEMA practical effect, and it licenses specific banks and institutions as Authorised Dealers (Category I, II and III, graded by how wide a range of foreign exchange transactions each may handle) through whom foreign exchange transactions must legally flow. The RBI can also compound most FEMA contraventions, letting a party that has breached the Act settle the matter directly with the RBI on payment of a sum rather than face prosecution, though this route is explicitly closed for the Act's most serious category of violation (Section 3(a), broadly, illegal dealing in or transfer of foreign exchange) and for any contravention with a suspected money-laundering or national security angle. That carve-out is precisely where administration stops and enforcement begins: the RBI administers FEMA day to day, but prosecuting a serious or laundering-linked FEMA violation is the Enforcement Directorate's job, a separate agency under the Department of Revenue, Ministry of Finance, not the RBI. This site's External Sector chapter covers the RBI's actual exchange rate management and reserve numbers in depth; this section is about who writes and enforces the rules that govern them, deliberately kept apart from that reserves-and-numbers ground.

The RBI's forgotten role: building India's development banks

Before it settled into being purely a regulator and monetary authority, the RBI spent decades directly building the specialised institutions India's ordinary banking system wasn't reaching, then, deliberately, let go of them once each stood on its own. Two examples cover most of what UPSC actually tests here.

The Industrial Development Bank of India (IDBI) was set up on 1 July 1964 under its own Act of Parliament, originally as a wholly owned subsidiary of the RBI, to extend long-term finance to industry. It was delinked from the RBI in 1976 and transferred to direct Government of India ownership, well before its later conversion into a commercial bank in the 2000s.

The National Bank for Agriculture and Rural Development (NABARD) came into being on 12 July 1982, on the recommendation of the Committee to Review Arrangements for Institutional Credit for Agriculture and Rural Development (CRAFICARD), chaired by B. Sivaraman. NABARD was created precisely by transferring the RBI's own agricultural credit functions to it, along with the refinance functions of the erstwhile Agricultural Refinance and Development Corporation (ARDC), and the RBI held a substantial equity stake in NABARD for years afterward before divesting it to the Government of India. The pattern across both institutions is the one worth remembering: the RBI incubated a specialised lender out of its own functions, then handed over ownership once that lender could stand alone, keeping its own role focused on regulation and monetary policy rather than direct development lending.

Repo vs reverse repo: the direction that trips people up

A quick way to keep these straight: think of the RBI as a bank for banks. Repo rate is what banks pay the RBI to borrow, so a higher repo rate makes loans (and therefore spending) more expensive across the whole economy, cooling inflation. Reverse repo is what the RBI pays banks to park surplus money with it, used to absorb excess liquidity from the system.

Quick revision points

• RBI lends to banks and the government, never directly to private companies.
• RBI issues all currency except the one-rupee note and coins, which the Government of India issues.
• Quantitative tools (repo, CRR, SLR, OMO) change the total credit pool; qualitative tools (margin requirements, moral suasion) target specific sectors.
• MPC: 6 members (3 RBI + 3 external), meets at least 4 times a year, Governor has the casting vote.
• Inflation target: CPI at 4%, band of 2 to 6%, in force since 2016.
• RBI: constituted under the RBI Act, 1934, began operations 1 April 1935 as a shareholders' bank, nationalised 1 January 1949, separate from and 20 years before the 1969/1980 commercial bank nationalisations.
• Central Board: Governor + up to 4 Deputy Governors, 4 directors (one per Local Board), 10 other nominated directors, 1 government official; Deputy Governors and the government official attend but don't vote.
• LAF corridor: SDF (since 8 April 2022, 25 bps below repo, uncollateralised) is now the floor, replacing the fixed reverse repo rate; MSF (since 2011, 25 bps above repo, collateralised) is the ceiling; corridor width 50 bps.
• LTRO (Feb 2020): 1 to 3-year funds at the repo rate. TLTRO (Mar 2020): must be deployed into corporate bonds/CPs; TLTRO 2.0 targeted small/mid NBFCs and MFIs. Operation Twist (Dec 2019): simultaneous buy-long/sell-short OMO to pull down long-term yields.
• FEMA, 1999 (in force from 1 June 2000) replaced FERA, 1973, turning violations from criminal to civil offences; RBI administers it via Authorised Dealers and can compound most contraventions, but not Section 3(a) or money-laundering-linked ones, which go to the Enforcement Directorate.
• RBI built and then let go of development institutions: IDBI (1964, delinked 1976) and NABARD (1982, via CRAFICARD, taking over RBI's own agricultural credit functions).

Once the tools and roles are clear, practise the statement-based questions UPSC builds around them.
