Money and the Reserve Bank of India
Functions of money, money supply measures M0 to M4, money multiplier, and the RBI's history, governors and functions for CGPSC Prelims and Mains.
Prerequisites
- Basic Concepts of the Economy: nominal vs real values, GDP and the sectors of the economy
- Money, Banking and Inflation: chapter overview: how the four topics fit together
The Hook: The ₹500 Note in Your Pocket
A paddy farmer from Mahasamund sells his crop at the procurement centre and the money reaches his bank account. He withdraws a few ₹500 notes at the Chhattisgarh Gramin Bank branch and spends them at the Saturday haat. Look closely at one note. It says “I promise to pay the bearer the sum of five hundred rupees” and is signed by the Governor of the Reserve Bank of India. A ₹1 note, though, is signed by the Finance Secretary.
Why does a piece of paper carry a “promise”? Who decides how many such notes exist, and how much “money” is there in India once bank deposits are counted? This page answers these questions.
Why it matters: Prelims regularly tests the components of M1 and M3, the RBI’s year of establishment and nationalisation, and who issues which currency. Mains uses this base for questions on central bank autonomy and the RBI’s role.
Money (मुद्रा): Functions and Forms
Why money replaced barter
Under barter (वस्तु विनिमय), goods are exchanged directly for goods. It fails because of the lack of a double coincidence of wants, the lack of a common measure of value, indivisibility of goods, and the difficulty of storing value and making deferred payments. Money solves all four problems.
Functions of money
| Type | Function | Meaning |
|---|---|---|
| Primary | Medium of exchange | Accepted in payment for goods and services |
| Primary | Measure of value (unit of account) | Prices of all goods are expressed in one unit, the rupee |
| Secondary | Store of value | Purchasing power can be kept for future use (inflation weakens this) |
| Secondary | Standard of deferred payment | Loans and future contracts are written in money terms |
| Contingent | Basis of credit, distribution of income, liquidity | Derived from the above |
Forms of money
- Commodity money: has value as a good (grain, cattle, gold coins).
- Fiat money (आदेश मुद्रा): paper notes and coins with no intrinsic value; accepted because the State declares them legal tender. Indian currency today is fiat money.
- Legal tender (वैध मुद्रा): must be accepted in settlement of debt. RBI notes are unlimited legal tender. Coins are limited legal tender under the Coinage Act, 2011.
- Bank money (credit money): demand deposits that can be transferred by cheque, card, UPI and similar instruments. Accepting it is optional, so it is not legal tender, but it is the largest part of money supply.
- Digital rupee (e₹): the RBI’s Central Bank Digital Currency (CBDC). It is a legal tender issued by the RBI in digital form. Pilots began for the wholesale segment on 1 November 2022 and for the retail segment on 1 December 2022. Unlike UPI, which moves bank deposits, e₹ is a direct claim on the RBI.
Measures of Money Supply (मुद्रा पूर्ति)
Money supply is the stock of money held by the public (households, firms and others, excluding the Government and the banking system) at a point in time. It is a stock, not a flow.
| Measure | Definition | Nickname |
|---|---|---|
| M0 (Reserve money) | Currency in circulation + bankers’ deposits with the RBI + “other” deposits with the RBI | High-powered money |
| M1 | Currency with the public + demand deposits with banks + “other” deposits with the RBI | Narrow money |
| M2 | M1 + savings deposits with post office savings banks | |
| M3 | M1 + net time deposits with banks | Broad money (aggregate monetary resources) |
| M4 | M3 + total deposits with the post office savings organisation (excluding National Savings Certificates) |
- Liquidity: M1 is the most liquid and M4 the least liquid.
- “Other deposits with the RBI” are deposits of quasi-government bodies, foreign central banks and international bodies such as the IMF and World Bank. They exclude the deposits of the Government and of banks.
- The RBI’s Second Working Group on Money Supply (chaired by Y.V. Reddy, 1998) introduced new monetary aggregates (NM0–NM3) and liquidity aggregates (L1–L3). M3 remains the measure most quoted in exam questions.
Money multiplier (मुद्रा गुणक)
Banks keep only a fraction of deposits as reserves and lend the rest. Each loan becomes a deposit somewhere else, so a rupee of reserve money supports several rupees of broad money.
$$\text{Money multiplier} = \frac{M3}{M0}$$In the simplest textbook case, with a reserve ratio \(r\) and no cash leakage, the deposit multiplier is \( \frac{1}{r} \). For example, if \(r = 10\%\) the multiplier is 10. A higher CRR lowers the multiplier. A lower CRR raises it. This is why CRR is a monetary policy tool (see Monetary Policy).

- The Governor and Deputy Governors are appointed by the Central Government for a term of up to five years, and are eligible for reappointment.
- The RBI’s accounting year was changed from July–June to April–March, starting from 2020-21, to match the Government’s financial year.
- The RBI has a regional office at Raipur for Chhattisgarh.

Currency management
- Minimum Reserve System (1957): the RBI must hold reserves worth at least ₹200 crore, of which at least ₹115 crore must be gold. Note issue is not tied to a fixed proportion of gold, so it is a fiat system.
- Note presses: Nashik and Dewas (owned by the Government through SPMCIL); Mysuru and Salboni (owned by the RBI through BRBNMPL).
- Mints (Government): Mumbai, Hyderabad, Kolkata, Noida.
- Demonetisation: On 8 November 2016, the ₹500 and ₹1,000 notes of the then series ceased to be legal tender. On 19 May 2023, the RBI announced the withdrawal of ₹2,000 notes from circulation, though they remain legal tender.
Memory Tricks
Don’t Confuse
| This | vs | That |
|---|---|---|
| M0: reserve money, includes bankers’ deposits with the RBI | vs | M1: money with the public, includes demand deposits with banks |
| M1: narrow money, most liquid | vs | M3: broad money, adds time deposits |
| ₹1 note: Government of India, signed by the Finance Secretary | vs | ₹2 and above: RBI, signed by the Governor |
| e₹ (CBDC): a liability of the RBI | vs | UPI payment: transfers a bank deposit, a liability of a commercial bank |
| RBI Act, 1934: establishes the RBI | vs | Banking Regulation Act, 1949: regulates banks |
Common Mistakes
- “The RBI was set up in 1949.” Wrong. It was set up in 1935 and nationalised in 1949.
- “The RBI was established on the recommendation of the Hilton Young Commission in 1935.” The Commission reported in 1926. The Act was passed in 1934.
- “M3 is narrow money.” M3 is broad money. M1 is narrow money.
- “Government deposits with the RBI are part of ‘other deposits’.” No. Government deposits are excluded from money supply.
- “The RBI mints coins.” Coins are minted by the Government of India. The RBI only distributes them.
- “Digital rupee is just another name for UPI.” No. e₹ is central bank money. UPI is a payment system for bank money.

Level 3: Mains Answer Writing
Q1. (60 words) Distinguish between narrow money and broad money.
Model answer outline
- Narrow money (M1): currency with the public + demand deposits with banks + other deposits with the RBI. Most liquid; used for transactions.
- Broad money (M3): M1 + net time deposits with banks. Includes savings held for longer periods; the RBI’s main measure of monetary resources.
- Conclusion: M3 grows faster than M1 as banking spreads, so the gap between them reflects financial deepening.
Q2. (150–200 words) Describe the functions of the Reserve Bank of India. How has its role changed since 2016?
Model answer outline
- Intro: The RBI, set up in 1935 under the RBI Act, 1934, and nationalised in 1949, is India’s central bank.
- Body:
- Issuer of currency (Section 22), under the Minimum Reserve System of 1957.
- Banker to Government: Centre by statute, States by agreement; manages public debt.
- Banker’s bank and lender of last resort; holds CRR balances.
- Regulator and supervisor of banks and NBFCs (Banking Regulation Act, 1949).
- Forex manager (FEMA, 1999) and payment systems regulator (PSS Act, 2007).
- Developmental role: priority sector lending and financial inclusion.
- Change since 2016: The amended RBI Act made price stability the primary objective, with a 4% CPI target and a six-member MPC that sets the repo rate by vote. Decisions are now rule-based and transparent.
- Chhattisgarh angle: The RBI’s developmental functions (lead bank scheme, financial literacy, oversight of Chhattisgarh Gramin Bank through NABARD) matter for the state’s tribal and rural districts.
- Conclusion: The RBI has moved from a multi-objective central bank to an inflation-targeting one, while keeping wide regulatory and developmental duties.
