**Money** is the commonly accepted medium of exchange in an economy. It becomes essential whenever multiple economic agents engage in market transactions. Without money, exchanges would rely on **barter** — direct exchange of goods and services — which involves the problem of **double coincidence of wants** (both parties must have what the other needs).
Money solves the double coincidence of wants problem. Instead of searching for someone who has exactly what you want and wants exactly what you have, individuals can:
**Example:** A farmer with surplus rice need not find a cloth merchant with surplus cloth. Instead, the farmer sells rice for money and uses money to buy cloth from anyone.
**Unit of Account**
**Store of Value**
**Standard of Deferred Payment**
**Cashless society** — financial transactions occur through digital transfer of information rather than physical currency notes or coins.

**Demand for money** refers to the quantity of money people desire to hold at different levels of income and interest rates.
**Factors determining money demand:**
1. **Income Level** — The larger the volume of transactions to be conducted, the greater the money needed
2. **Interest Rate** — When interest rates rise, holding money (which earns no interest) becomes costlier
**Relationship:** Money demand is **positively related to income** and **negatively related to interest rate**
In modern economies, **money supply** comprises:
Money supply is created by two institutions:
1. **Central Bank** — issues currency
2. **Commercial banking system** — creates deposits through lending
---
**Central Bank** is the apex financial institution responsible for monetary management. India's central bank is the **Reserve Bank of India (RBI)**, established in 1935.
1. **Currency Authority** — Sole institution authorized to issue currency notes and coins
2. **Money Supply Control** — Regulates total money in the economy through:
3. **Banker to Government**
4. **Custodian of Foreign Exchange Reserves** — Manages country's foreign currency reserves
5. **Banker's Bank (Lender of Last Resort)**
---
**Commercial banks** are financial institutions that:
The chapter uses the goldsmith Lala's story to explain credit creation:
---
A **balance sheet** records assets (left side) and liabilities (right side); both must equal.
**Assets** = what bank owns or claims on others:
**Liabilities** = what bank owes:
**Accounting Rule:** Assets = Liabilities + Net Worth
Where: **Net Worth** = Assets − Liabilities
**Scenario:** Ms Fernandes deposits Rs 100 in a new bank; bank deposits Rs 100 with RBI as reserves.
| Assets | Liabilities |
|--------|-------------|
| Reserves: Rs 100 | Deposits: Rs 100 |
| | **Net Worth: Rs 0** |
| **Total: Rs 100** | **Total: Rs 100** |
**Money Supply (M1)** = Currency + Deposits = 0 + 100 = **Rs 100**
**Cash Reserve Ratio (CRR)** — Percentage of total deposits that a bank must maintain as cash reserves with the RBI; set by RBI as legal requirement.
**Example with CRR = 20%:**
**SLR** — Minimum percentage of deposits banks must keep in liquid form (short-term financial instruments) for short-term liquidity management.
---
**Initial conditions:**
**Round 1:**
**Round 2:**
**Process continues** until all original reserves (Rs 100) exactly equal required reserves.
**Final equilibrium:**
| Final Balance Sheet Assets | Final Balance Sheet Liabilities |
|-----------------------------|--------------------------------|
| Reserves: Rs 100 | Deposits: Rs 500 |
| Loans: Rs 400 | **Total: Rs 500** |
| **Total: Rs 500** | |
**Final Money Supply:** M1 = 0 + 500 = **Rs 500**
**Money Multiplier (k)** = 1 / CRR
**Credit Creation Formula:** Total Deposits = Initial Reserves × Money Multiplier
**Example calculation:** Rs 100 × 5 = **Rs 500 total deposits**

RBI uses **quantitative tools** (control money supply volume) and **qualitative tools** (encourage/discourage lending).
**1. Cash Reserve Ratio (CRR)**
**2. Bank Rate (Discount Rate)**
**3. Open Market Operations (OMO)**
**4. Repo Rate and Reverse Repo Rate** (Modern additions)
---
RBI stands ready to provide funds to commercial banks facing liquidity crises, ensuring:
This role is crucial during financial stress or bank runs.
---
1. **Money functions:** Medium of exchange, unit of account, store of value, standard of deferred payment
2. **Demand for money** increases with income, decreases with interest rate
3. **CRR** is legal minimum reserve percentage; acts as binding constraint on lending
4. **Money multiplier = 1/CRR** — shows how much total deposits one rupee of reserves creates
5. **Credit creation process:** Each round of lending deposits funds in bank, creating new lending capacity
6. **RBI policy tools:** CRR, Bank Rate, OMO are quantitative tools; most direct control via CRR changes
7. **OMO mechanism:** Buying bonds injects liquidity; selling bonds withdraws liquidity
8. **SLR** requires short-term liquid asset holdings beyond CRR
Q1. In a barter system, why does the 'double coincidence of wants' problem become more severe as the economy grows larger?
Answer: B — As economy size increases, the probability of finding someone with exactly what you want and who wants exactly what you have decreases dramatically, raising search costs.
Q2. If the general price level in an economy increases by 20%, what happens to the purchasing power of money?
Answer: C — Purchasing power is inversely related to price level; if prices rise 20%, money buys 1/1.2 = 0.833 of what it did before, a loss of 16.67% of purchasing power.
Q3. Which of the following is NOT a function of money in a modern economy?
Answer: C — Money does not determine production technology; this is decided by firms based on input availability and costs, while money only facilitates exchange and stores value.
Q4. Why is money superior to gold jewellery as a store of value for daily use?
Answer: B — Money is non-perishable, has low storage costs, and is universally accepted, whereas gold requires authentication, melting, and purity verification for transactions.
Q5. The Reserve Bank of India issues currency called high-powered money. This is also known as:
Answer: B — High-powered money (reserve money) issued by RBI serves as the basis or foundation upon which commercial banks create credit through the money multiplier process.
Q6. When interest rates in the economy increase from 5% to 8%, how does this affect the demand for money?
Answer: B — Higher interest rates increase the opportunity cost of holding non-interest-bearing money, so people shift to interest-earning bank deposits, reducing money demand.
Q7. An individual's income rises from Rs 40,000 to Rs 50,000 per month. Based on the demand for money theory, what would be the expected change?
Answer: C — As income increases, the volume of transactions increases, necessitating a larger quantity of money to conduct these expanded economic activities.
Q8. Which statement correctly describes the relationship between commercial banks and the money supply system? (Both statements below)
Answer: B — In modern economies, both institutions participate in money creation: RBI issues high-powered money, and commercial banks create credit by lending deposits, expanding money supply.
Q9. Assertion: Money serves as a unit of account. Reason: This allows all commodity values to be expressed in a common metric, making price comparisons easy. Which is correct?
Answer: C — Money's unit of account function means all values are measured in monetary units (rupees), which directly enables easy price comparisons like pen = 5 pencils.
Q10. HOTS: If the RBI decides to increase the quantity of high-powered money in circulation, and the reserve requirement ratio is 10%, by how much would the total money supply potentially increase if all created credit is fully utilized?
Answer: C — Money multiplier = 1/CRR = 1/0.10 = 10; therefore, if high-powered money increases by X, total money supply increases by 10X, assuming full credit utilization.
What is the primary function of money in an economy?
Money acts as a medium of exchange, allowing people to avoid the inefficiencies of barter by providing a universally acceptable means of transaction.
Define the double coincidence of wants problem.
In barter, both parties must want exactly what the other has to offer at the same time, which becomes increasingly difficult and costly in a large economy.
How does money function as a unit of account?
Money provides a common standard for expressing the value of all goods and services, allowing relative prices to be calculated easily (e.g., one pen = 5 pencils).
What is the relationship between price level and purchasing power of money?
When general price levels rise, the purchasing power of money deteriorates because each unit of money can buy fewer goods and services.
Why is money superior to rice as a store of value?
Money is non-perishable, has low storage costs, and is universally acceptable at any time, whereas rice spoils, requires space, and has limited acceptability.
What is 'high-powered money' issued by the central bank?
High-powered money (reserve money) is currency issued by the central bank that serves as the basis for credit creation by commercial banks.
What are the two main institutions that create money in a modern economy?
The central bank (RBI in India) issues currency, and commercial banks create credit through accepting deposits and lending.
How do interest rates affect the demand for money?
When interest rates rise, the opportunity cost of holding money increases, so people prefer to keep savings in interest-earning deposits rather than hold cash.
Why does income influence the demand for money?
Higher income leads to more transactions, so people need larger quantities of money to conduct their increased economic activity.
What is a cashless economy and which government initiative supports it in India?
A cashless economy relies on digital transactions instead of physical cash; initiatives like Jan Dhan, Aadhaar-enabled payments, and e-wallets promote this in India.
Define money and explain why the barter system becomes inefficient in a large economy. Give one reason. [2 marks]
Define money as universally accepted medium of exchange. Explain double coincidence of wants and rising search costs as economy grows. One reason is sufficient (e.g., difficulty finding matching trading partners).
Explain the four functions of money with one example for each function. Which function makes money superior to commodities like rice or gold as a store of value? [5 marks]
List four functions: (1) Medium of exchange — transactions, (2) Unit of account — price comparison, (3) Store of value — preserve wealth, (4) Standard of deferred payment — future payments. For each give one concrete example (e.g., buying groceries, comparing pen and pencil prices, saving for future, paying loan next month). For superiority: money is non-perishable, low storage cost, universally accepted compared to rice (perishable, space-consuming) or gold (needs authentication, melting costs).
Analyse how income and interest rates jointly determine the demand for money in an economy. Use a numerical example to show the combined effect of these two factors on money demand. [6 marks]
Demand for money depends on: (1) Income — higher income means more transactions, more money needed; (2) Interest rate — higher rates increase opportunity cost of holding non-interest-bearing money, so demand falls. Example: If monthly income Rs 50,000 (demands more money for Rs 5,000 in transactions) but interest rates rise from 5% to 10%, person shifts savings to deposits, reducing money holdings. Show both factors moving in opposite directions and their net effect on quantity of money an individual would want to hold.
