Money and Banking

What is Money?

In simple terms, money is anything that is generally accepted by people as a payment for goods and services or for the repayment of debts. It isn't just paper notes; it is a "tool" that solves the problem of trading.

The Evolution of Money

Money evolved as humans found easier ways to trade:

• Barter System: Directly exchanging goods for goods (e.g., 5 kg of wheat for 1 kg of honey).
• Commodity Money: Using items with intrinsic value (e.g., gold, silver, or salt).
• Metallic Money: Standardized coins made of gold or silver.
• Paper Money: Notes issued by the government/central bank (Fiat money).
• Digital/Electronic Money: Credit cards, UPI, Net Banking, and Crypto.

Key Points

• Money removes the need for "Double Coincidence of Wants".
• It acts as a bridge between the producer and the consumer.

Examples

• Ancient: Cowrie shells were used in India as a medium of exchange.
• Modern: Using a QR code to pay for a chai.

A. Primary Functions

• Medium of Exchange: Simplifies trade; you can buy anything using money.
• Measure of Value (Unit of Account): Acts as a measuring tape for value (e.g., "this phone costs $500" instead of "10 bags of rice").

B. Secondary Functions

• Store of Value: Allows saving for future use. You can't store fresh fish for ten years, but you can store the money earned from selling it.
• Standard of Deferred Payments: Facilitates loans and credit; borrowing today and paying in the future.

Examples

• Store of Value: Putting money in a savings account for college.
• Deferred Payment: Taking an EMI for a smartphone.

Money supply refers to the total stock of money circulating in an economy at a particular point in time.

Components of Money Supply

1. Currency held by the Public: Coins and paper notes in wallets and business cash.
2. Net Demand Deposits: Money in bank accounts (Savings/Current) that can be withdrawn instantly.

Key Point: The government and Central Bank monitor money supply to control inflation. Too much money usually leads to rising prices.

Commercial banks use the Credit Creation process to multiply money in the economy.

How it Works

1. A person makes a Primary Deposit (e.g., $1,000).
2. The bank keeps a Legal Reserve Ratio (LRR) and lends the rest.
3. The loan is deposited back into the banking system as a Derivative Deposit.
4. The cycle repeats, multiplying the original amount.

The Formulas

Numerical Illustration

The Central Bank (e.g., RBI, Federal Reserve) is the apex body controlling the banking system.

Key Functions

• Currency Authority: Sole power to issue banknotes.
• Banker to the Government: Manages govt accounts and loans.
• Banker's Bank: Lender of last resort for commercial banks.
• Controller of Credit: Manages inflation and deflation.

Monetary Policy Tools (The "Control Knobs")

• CBDC (Central Bank Digital Currency): Government-backed digital currency (e.g., Digital Rupee). Safer than crypto.
• Neobanks: Digital-only banks with no physical branches (e.g., Chime, NuBank).
• FinTech Algorithms: AI-driven creditworthiness checks that speed up money creation.

Scenario: The country of "Economia" sees prices rise by 15% in six months. The Central Bank applies a "Dear Money Policy" (Contractionary Policy).

The Strategy:

• Step 1: Increase Repo Rate (4% $\rightarrow$ 6%). Commercial borrowing becomes expensive.
• Step 2: Banks increase interest rates for the public.
• Step 3: Increase CRR (3% $\rightarrow$ 5%). Banks lock more cash away.
• Step 4: Increase Reverse Repo Rate. Banks prefer parking money with the Central Bank.

The Result: Borrowing drops $\rightarrow$ Spending drops $\rightarrow$ Demand falls $\rightarrow$ Inflation returns to a manageable 4%.

   Ans: c
3. Money Supply includes:
   a) Only coins | b) Currency with public + Demand Deposits | c) Only fixed deposits | d) Gold reserves
   Ans: b

   a) $LRR \times 1$ | b) $1 / LRR$ | c) $Deposit \times LRR$ | d) $1 + LRR$
   Ans: b
5. If LRR is 20%, the money multiplier will be:
   a) 2 | b) 5 | c) 10 | d) 20
   Ans: b
6. Who has the sole authority to issue currency notes?
   a) Commercial Banks | b) Ministry of Finance | c) Central Bank | d) World Bank
   Ans: c
7. Raising the Repo Rate generally leads to:
   a) More loans | b) Lower interest rates | c) Decrease in inflation | d) Increase in money supply

   a) Themselves | b) The Central Bank | c) The Government | d) The Public
   Ans: b
9. Which rate is used for long-term lending by the Central Bank?
   a) Repo Rate | b) Bank Rate | c) Reverse Repo Rate | d) SLR

    a) Standard Liquidity Ratio | b) Statutory Liquidity Ratio | c) Secure Lending Ratio | d) Systemic Loan Ratio

1. Q: Distinguish between Barter and Money.
   Ans: Barter is the direct exchange of goods for goods, requiring a double coincidence of wants. Money is a medium of exchange accepted by everyone, removing that need.
2. Q: Explain the "Store of Value" function of money.
   Ans: Money allows people to transfer purchasing power from the present to the future without the physical decay associated with perishable goods.
3. Q: How does a commercial bank create credit?
   Ans: Banks keep a fraction of deposits (LRR) and lend the rest. The loan is deposited back into the system as a new deposit, multiplying the money.
4. Q: What is the difference between Repo Rate and Bank Rate?
   Ans: Repo Rate is for short-term lending against securities; Bank Rate is for long-term lending without collateral.
5. Q: How does the Central Bank control inflation using CRR?
   Ans: By increasing CRR, banks must keep more cash with the Central Bank, reducing lendable funds, which lowers spending and prices.
6. Q: Define Demand Deposits. Why are they considered money?
   Ans: Funds in current/savings accounts withdrawable on demand. They are money because they facilitate payments via cheques/digital transfers.
7. Q: What happens when the Reverse Repo Rate is increased?
   Ans: Banks earn more by parking funds with the Central Bank, leading them to lend less to the public, reducing money supply.
8. Q: Explain the concept of "Lender of Last Resort."
   Ans: When commercial banks face a crisis and can't get funds elsewhere, the Central Bank provides liquidity to maintain stability.
9. Q: Why is SLR important for a bank?
   Ans: It ensures banks maintain liquid assets (cash/gold) to protect against sudden large-scale withdrawals.
10. Q: What is the relationship between LRR and the Money Multiplier?
    Ans: Inverse relationship. Higher LRR means a lower Money Multiplier (less lending capacity).

• Functions of Money (M-S-S-M): Medium of exchange, Store of value, Standard of deferred payment, Measure of value.
• Inflation Control (The "UP" Logic): To stop Inflation $\rightarrow$ Push UP the rates (Repo $\uparrow$, CRR $\uparrow$, SLR $\uparrow$). This is "Dear Money Policy".
• CRR vs SLR: CRR = Central Bank; SLR = Self (Bank keeps it).
