The Hook: The ₹500 Note in Your Pocket

Connect

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

TypeFunctionMeaning
PrimaryMedium of exchangeAccepted in payment for goods and services
PrimaryMeasure of value (unit of account)Prices of all goods are expressed in one unit, the rupee
SecondaryStore of valuePurchasing power can be kept for future use (inflation weakens this)
SecondaryStandard of deferred paymentLoans and future contracts are written in money terms
ContingentBasis of credit, distribution of income, liquidityDerived 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.

MeasureDefinitionNickname
M0 (Reserve money)Currency in circulation + bankers’ deposits with the RBI + “other” deposits with the RBIHigh-powered money
M1Currency with the public + demand deposits with banks + “other” deposits with the RBINarrow money
M2M1 + savings deposits with post office savings banks
M3M1 + net time deposits with banksBroad money (aggregate monetary resources)
M4M3 + 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.

Functions of the RBI

Payment systemsRegulates payment and settlement systems (RTGS, NEFT; UPI through NPCI)Payment and Settlement Systems Act, 2007
Developmental rolePriority sector lending, financial inclusion, financial literacyVarious

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.
Autonomy of the RBI: a Mains theme
Section 7 of the RBI Act lets the Central Government give directions to the RBI “in the public interest” after consulting the Governor. Debates about the RBI’s surplus transfer to the Government, its capital reserves (the Bimal Jalan Committee, 2019, on the economic capital framework) and the 2016 inflation-targeting law all turn on one question: how far should an unelected central bank be independent of an elected government? A balanced answer accepts the RBI’s accountability to Parliament and the Government while protecting its operational independence in setting interest rates.

Memory Tricks

M-ladder: '1 Demand, 3 Time'
M1 = Cash + Demand deposits (+ other RBI deposits). M3 adds Time deposits with banks. M2 and M4 simply add Post Office deposits to M1 and M3. So: odd numbers (1, 3) are about banks; even numbers (2, 4) add the post office.
RBI dates: 26-34-35-37-49
Commission ‘26 → Act ‘34 → Start ‘35 → Bombay ‘37 → Nationalised ‘49. Read it as a cricket score: 26, 34, 35, 37, 49 not out.

Don’t Confuse

Common Mistakes

MCQ traps
  • “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.

Practice

All questions below are original practice questions written in CGPSC style. They are not previous-year questions.

Level 1: Foundation

  1. The lack of a ______ of wants is the main defect of barter.
  2. Broad money in India is denoted by ______.
  3. The first Indian Governor of the RBI was ______.
Answers
  1. Double coincidence.
  2. M3 (M1 + net time deposits with banks).
  3. Sir C.D. Deshmukh (1943–49).

Level 2: Prelims MCQs

Q1. Consider the following statements about the Reserve Bank of India:

  1. It began operations on 1 April 1935 with its central office in Calcutta.
  2. It was established as a wholly Government-owned bank.
  3. Its central office moved permanently to Bombay in 1937.

Which of the statements given above is/are correct?

  • (a) 1 only
  • (b) 1 and 3 only
  • (c) 2 and 3 only
  • (d) 1, 2 and 3
Answer and explanation
(b) 1 and 3 only. The RBI began as a shareholders’ bank (privately owned) and became Government-owned only on 1 January 1949, so statement 2 is wrong. It started in Calcutta on 1 April 1935 and moved to Bombay in 1937.

Q2. Which of the following is not a component of M1 in India?

  • (a) Currency with the public
  • (b) Demand deposits with banks
  • (c) Net time deposits with banks
  • (d) Other deposits with the RBI
Answer and explanation
(c) Net time deposits with banks. Time deposits are added to M1 to get M3 (broad money). M1 consists of currency with the public, demand deposits with banks and other deposits with the RBI.

Q3. Match List I (Item) with List II (Issuing or signing authority):

List IList II
A. ₹1 currency note1. Governor, RBI
B. ₹100 currency note2. Finance Secretary, Government of India
C. Coins3. Minted by the Government of India
D. Digital rupee (e₹)4. Issued by the RBI as CBDC
  • (a) A-1, B-2, C-3, D-4
  • (b) A-2, B-1, C-4, D-3
  • (c) A-2, B-1, C-3, D-4
  • (d) A-3, B-1, C-2, D-4
Answer and explanation
(c) A-2, B-1, C-3, D-4. The ₹1 note is a Government of India note signed by the Finance Secretary. All other notes are RBI notes signed by the Governor. Coins are minted by the Government. The e₹ is the RBI’s central bank digital currency.

Q4. If the cash reserve ratio is raised, other things remaining the same, the money multiplier will:

  • (a) rise
  • (b) fall
  • (c) remain unchanged
  • (d) first rise, then fall
Answer and explanation
(b) fall. A higher reserve ratio means banks can lend out a smaller share of each deposit, so each rupee of reserve money creates fewer rupees of deposits. In the simple case the multiplier is \( \frac{1}{r} \), which falls as \(r\) rises.

Q5. Arrange the following monetary aggregates in decreasing order of liquidity:

  1. M4
  2. M1
  3. M3
  4. M2
  • (a) 2, 4, 3, 1
  • (b) 1, 3, 4, 2
  • (c) 2, 3, 4, 1
  • (d) 4, 2, 1, 3
Answer and explanation
(a) 2, 4, 3, 1, that is M1 > M2 > M3 > M4. Liquidity falls as less liquid items (post office savings, then time deposits, then all post office deposits) are added.

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:
    1. Issuer of currency (Section 22), under the Minimum Reserve System of 1957.
    2. Banker to Government: Centre by statute, States by agreement; manages public debt.
    3. Banker’s bank and lender of last resort; holds CRR balances.
    4. Regulator and supervisor of banks and NBFCs (Banking Regulation Act, 1949).
    5. Forex manager (FEMA, 1999) and payment systems regulator (PSS Act, 2007).
    6. 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.
