Money Supply Measures: From Pocket Money to the Whole Economy
Think about the money you actually use. You have some cash in your wallet, maybe a few coins for the bus. You might have a ₹500 note tucked away. But you also have money in your bank account — the kind you can swipe on a card or transfer through UPI. That's money too, even though you never see it as paper.
Now imagine the entire country. Every person, every shop, every company, every government office — all the money they hold in cash and in their bank accounts. That total is what economists call the money supply. It's not just the currency printed by the RBI. It's the total stock of money available in the economy at a given point in time.
Why does this matter?
The money supply affects everything: how much prices rise (inflation), how easily you can get a loan, how much the government can spend, and even the value of the rupee. The RBI controls the money supply to keep the economy stable. But to control it, you first need to measure it — and that's where the confusion begins.
The problem: Not all money is the same
A ₹100 note in your pocket is clearly money. But what about the ₹10,000 sitting in your savings account? You can't hand that to a shopkeeper as a physical note, but you can withdraw it anytime or pay via UPI. So it's almost as good as cash.
What about a fixed deposit of ₹1 lakh? You can't use it to buy lunch today — you'd have to break the deposit, which takes time and may cost you interest. So it's less "money-like" than cash, but it's still a form of stored purchasing power.
The RBI solves this by defining four measures of money supply, each broader than the last. They are called M1, M2, M3, and M4. Think of them as concentric circles: M1 is the narrowest (most liquid), M4 is the broadest (includes less liquid forms).
The four measures (as per NCERT Class 12)
M1=CU+DD
M2=M1+Savings deposits with Post Office Savings Banks
M3=M1+Net time deposits with the banking system
M4=M3+Total deposits with Post Office Savings Banks (excluding NSC)
Where:
- CU = Currency held by the public (notes + coins, excluding cash held by banks)
- DD = Net demand deposits of banks (the money in your current and savings accounts that you can withdraw on demand)
- Net time deposits = Fixed deposits, recurring deposits, etc. — money you cannot withdraw immediately without penalty
What each measure captures
M1 is the money you can spend right now — cash in hand plus money in your bank account that you can withdraw or transfer instantly. This is called narrow money. It's the most liquid.
M2 adds post office savings deposits. In India, post offices also accept savings deposits, and these are quite liquid (you can withdraw them on demand). But they're not part of the commercial banking system, so they're added separately.
M3 is the most commonly used measure for policy. It adds all time deposits (fixed deposits, etc.) to M1. This is called broad money. Why include fixed deposits? Because they can be converted into cash quickly (though with some loss of interest). They represent purchasing power that is just a step away from being spendable.
M4 adds post office deposits (excluding National Savings Certificates, which are less liquid) to M3. This is the broadest measure.
Which one do economists actually use?
In India, the RBI primarily tracks M3 for monetary policy. You'll see it in news headlines: "Money supply (M3) grew by 10% this year." M1 is also tracked for short-term liquidity analysis.
The RBI publishes these numbers every week. As of recent data (you don't need to memorise exact figures), M3 is roughly ₹200+ lakh crore — a number so large it's hard to imagine. But the growth rate is what matters for policy. …
Bank rate is a tool of monetary policy. It is the rate of interest at which the central bank (RBI) lends long-term funds to commercial banks. …
Bank rate = the interest rate at which the RBI lends to commercial banks, used to control credit and money supply.
The bank rate is the rate of interest charged by the central bank (the Reserve Bank of India) on long-term loans and advances it gives to commercial banks. It is an important quantitative instrument of monetary policy: when the RBI raises the bank rate, borrowing by commercial banks becomes costlier, they raise their own lending rates, credit contracts and money supply falls; a cut …

- CBSE 2026Set 58/1/11 markMCQQ.‘In an economy, the currency held by the public, Net Demand Deposits with Commercial Banks and Net Time Deposits with Commercial Banks stand at ₹ 1,42,000 crore, ₹ 22,000 crore and ₹ 86,000 crore respectively. The value of Money Supply (M₁) would be ₹ __________ crore. (Choose the correct option to fill in the blank) Options : (A) 2,50,000 (B) 86,000 (C) 1,64,000 (D) 1,42,000
›Reveal solutionSolution
M₁ is the narrowest measure of money supply, defined as currency with the public plus net demand deposits with banks. Using the given data, M₁ = ₹1,42,000 + ₹22,000 = ₹1,64,000 crore.
Money supply measures are classified by liquidity — how quickly an asset can be used for transactions. The narrowest and most commonly used measure in India is M₁, which includes only the most liquid forms of money: currency held by the public (notes and coins outside the banking system) and net demand deposits with commercial banks (savings and current accounts that can be withdrawn on demand). Time deposits, like fixed deposits, are less liquid and are not part of M₁ — they belong to broader measures like M₃.
The formula for M₁ is straightforward:
M1=Currency with the public+Net demand deposits with commercial banks
Given:
- Currency held by the public = ₹1,42,000 crore
- Net demand deposits = ₹22,000 crore …
- CBSE 2026Set 58/2/11 markMCQQ.Sumit deposited ₹ 10 lakh in his savings account. The deposits made by him is a part of ________ in the M₁ measure of money supply. (Choose the correct option to fill in the blank) Options : (A) Currency held by public (B) Interbank deposits (C) Demand deposits with commercial banks (D) Term deposits with Reserve Bank of India (RBI)
›Reveal solutionSolution
The key idea is that M₁ money supply includes only the most liquid forms of money. Sumit’s ₹10 lakh in a savings account is a demand deposit with a commercial bank, so it falls under option (C).
To understand why, we need to recall how the Reserve Bank of India (RBI) defines the money supply. The narrowest measure, M₁, is designed to capture money that can be used immediately for transactions — the most liquid assets in the economy. It consists of:
- Currency held by the public (notes and coins in people’s hands, not in bank vaults)
- Demand deposits with commercial banks (deposits that can be withdrawn on demand, like savings and current accounts)
- Other deposits with the RBI (a small category, mainly deposits of financial institutions)
Now, when Sumit deposits ₹10 lakh into his savings account, that money is no longer currency in his pocket. It becomes a deposit with his commercial bank. And crucially, a savings account is a demand deposit — he can withdraw it at any time without prior notice. That’s the defining feature: demand deposits are payable on demand, unlike term deposits (fixed deposits) which have a maturity period.
Watch outA common mistake is to think that savings account deposits are “term deposits” because they earn interest. But in India, savings accounts are legally demand deposits — you can write cheques or use a debit card against them. Term deposits (fixed deposits) are a separate category and belong to M₃, not M₁.
Let’s check the options:
- (A) Currency held by public — No. Once deposited, the currency is no longer “held by the public”; it’s with the bank. …

›Reveal solutionSolution
Aggregate monetary resources is the popular name for M3, so the correct option is (b) M3.
The RBI publishes four measures of money supply. M1 (narrow money) = currency with public + demand deposits + other deposits with RBI. M3 = M1 + net time deposits of commercial banks. M3 is the most widely used measure and is popularly called 'aggregate monetary resources' of the economy.

Currency is issued by the Central Bank, so the answer is C.
The central bank of a country (in India, the RBI) is the apex monetary institution and the only body legally empowered to issue currency notes, which keeps note issue uniform and under a single controlling authority. One-rupee notes and coins are technically issued by the Government of India, but the institution 'responsible for currency issue' as a whole is the central b …
- CBSE 2026Set ANNUAL1 markQ.What do you understand by money?
›Reveal solutionSolution
Money is anything generally accepted as a medium of exchange that also acts as a measure and store of value.
Money is any object or instrument that is widely accepted in exchange for goods and services and in the settlement of debts. It overcomes the problems of the barter system (such as the lack of double coincidence of wants) by acting as: a medium of exchange, a common measure/unit of value, a store of value, and a standard for deferred (future) payments. Currency notes, coins and bank deposits are the main forms of money in a modern economy. This is a co …
- CBSE 2026Set ANNUAL1 markQ.What do you mean by digital transactions?
›Reveal solutionSolution
Digital transactions are electronic, cashless payments made through channels like UPI, cards and net banking.
A digital transaction is the transfer of money carried out electronically, without the physical exchange of currency notes or coins. The payment is made and received through digital means — for example UPI, debit and credit cards, internet/net banking, NEFT/RTGS and mobile wallets — and the funds move directly between bank accounts. Such transactions make payments faster, more convenient and more transparent and are central to a 'less-cash' economy, a topic emphasised in the Cla …

- CBSE 2026Set ANNUAL1 markMCQQ.Money Multiplier is :(a) 1/CRR(b) Cash × 1/CRR(c) Cash × CRR(d) None of these(a) 1/CRR(b) Cash × 1/CRR(c) Cash × CRR(d) None of these
›Reveal solutionSolution
Money Multiplier = 1/CRR (not 'Cash × 1/CRR', which would instead give total money supply, not the multiplier itself).
In the simplest fractional-reserve banking model, if the Cash Reserve Ratio (CRR) is the fraction of deposits banks must keep as reserves, each rupee of initial (high-powered) money deposited gets lent out and re-deposited repeatedly, creating a geometric series of total deposits: Initial Deposit × (1 + (1−CRR) + (1−CRR)² + ...) = Initial Deposit × [1/CRR]. The term 1/CRR IS the Money Multiplier itself — the factor by which the initial cash/reserve base gets multiplied into the t …

›Reveal solutionSolution
M1 = Currency with the public + Net demand deposits with banks + Other deposits with RBI. Time deposits are excluded from M1.
The Reserve Bank of India classifies money supply into four measures (M1, M2, M3, M4) based on liquidity. M1, the most liquid measure, is defined as:
M1 = Currency with the public (C) + Net demand deposits with banks (DD) + Other deposits with RBI (OD)
Here, "other deposits with RBI" is not given (treated as zero), so:
M1 = Rs. 570 crore (currency with public) + Rs. 250 crore (net demand deposits) = Rs. 820 crore

- CBSE 2025Set 58/6/11 markMCQQ.Central Bank can decrease the money supply in the economy by __________. (Choose the correct option to fill in the blank) (A) lowering the cash reserve (B) increasing the bank rate (C) lowering the bank rate (D) purchase of G-Secs (Government Securities)
›Reveal solutionSolution
The Central Bank decreases the money supply by making it costlier or harder for commercial banks to lend. Increasing the bank rate does exactly that, so option (B) is correct.
To understand why, you first need to see how money supply works in a modern economy. Money isn't just the currency in your pocket — most of it is bank deposits created when banks lend. When a bank gives a loan, it credits the borrower's account, creating new deposit money. So the total money supply expands when banks lend more, and contracts when they lend less.
The Central Bank (RBI in India) controls this process through several tools. Each tool either encourages banks to lend more (increasing money supply) or discourages them from lending (decreasing money supply).
Let's examine each option:
Option (A): Lowering the cash reserve ratio (CRR)
CRR is the fraction of deposits banks must keep with the Central Bank as cash. If the RBI lowers CRR, banks have more free reserves to lend. More lending means more deposit creation — money supply increases, not decreases. So this is wrong.
Option (B): Increasing the bank rate
The bank rate is the interest rate at which the Central Bank lends to commercial banks (usually against long-term securities). When the bank rate rises, borrowing from the RBI becomes more expensive. Banks respond by borrowing less, which shrinks their reserves. With fewer reserves, they cut back on lending. Less lending means less deposit creation — money supply decreases. This is the correct answer.
Watch outA common mistake is confusing "bank rate" with "repo rate". Both are policy rates, but the bank rate is typically higher and used for longer-term borrowing. The logic, however, is the same: raising either rate makes funds costlier for banks, reducing their ability to create money.
Option (C): Lowering the bank rate …
- CBSE 2025Set ANNUAL1 markMCQQ.Read the following statements and choose the correct answer among the given alternatives: Statement 1: Stock of money held by the government is part of money supply. Statement 2: Demand deposits are not for a specific period of time.(a) Both the statements are true(b) Both the statements are false(c) Statement 1 is true and Statement 2 is false(d) Statement 1 is false and Statement 2 is true
›Reveal solutionSolution
Statement 1 is false, Statement 2 is true — answer (d).
Money supply is officially defined as the total stock of money held by the public (households and firms) at a point in time. "Public" deliberately excludes the government and the banking system itself — cash balances held by the government with the RBI are not counted as part of money supply, because the government is the issuer/regulator of money, not a holder of it in the economic sense. So Statement 1 ("Stock of money held by the government is part of money supply") is false.

- CBSE 2025Set ANNUAL1 markMCQQ.Miss Savita has deposited sum of ₹ 5 lakh with commercial bank for 5 years, which she cannot withdraw before stipulated time period is called ______ .(a) Demand deposits(b) Chequable deposits(c) Saving deposits(d) Non-chequable deposits
›Reveal solutionSolution
A fixed deposit locked for a stipulated period, not withdrawable on demand or by cheque, is classified as a non-chequable (time) deposit.
Bank deposits are broadly classified by how freely they can be withdrawn:
- Demand deposits: can be withdrawn by the depositor AT ANY TIME, on demand, usually operated through cheques (e.g., current account/savings account balances) — not applicable here since the question specifies the sum CANNOT be withdrawn before the stipulated period.
- Chequable deposits: deposits that can be operated/withdrawn by writing a cheque — again, not applicable since a locked fixed deposit is NOT cheque-operable. …
