Week 4: Supply of Money

I. Concept of Money Supply

  • Definition: The total quantity of money available in an economy at a particular point in time1.

  • Nature: It is a Stock Concept (measured at a specific time, not over a period)2.

  • Components: Includes physical currency (notes/coins) and liquid assets like bank deposits3.

  • Sources of Generation:

    1. Central Bank (RBI): Issues High-Powered Money (M0) and manages supply via policy tools (interest rates, reserves)4.

    2. Commercial Banks: Create money through lending (creating deposits in borrower accounts)5.


II. Measures of Money Supply (The "M"s)

  • M0 (High-Powered Money / Monetary Base):

    • Most liquid form; foundation for all other money6.

    • Formula: \(H = C + R\) (Currency in Circulation + Commercial Bank Reserves)7.

    • Includes excess reserves held by banks8.

  • M1 (Narrow Money):

    • Most liquid forms of money9.

    • Includes: Currency in Circulation + Demand Deposits + Other Deposits with Central Bank 10.

  • M2 (Broad Money):

    • Includes M1 + Savings Deposits + Time Deposits + Small Denomination Time Deposits + Money Market Mutual Funds (MMMFs) 11.
  • M3 (Even Broader Money):

    • Includes M2 + Large Time Deposits + Repurchase Agreements (RPs) + Institutional MMMFs 12.
  • M4 (Extended Money Supply):

    • Includes M3 + Post Office Savings13.

III. Determinants of Money Supply

  • Money Multiplier Effect:

    • Explains how banks expand money supply via fractional reserve banking14.

    • Formula: \(\text{Money Multiplier} = 1 / r\) (where \(r\) is the Required Reserve Ratio)15.

    • Inverse Relationship: A lower reserve ratio leads to a higher money multiplier (more money creation)16.

    • Example: If Reserve Ratio is 10% (0.10), the Multiplier is 1017.

  • Determinant Factors:

    • Public Preference: Higher preference for Bank Deposits (over cash) increases money supply; holding cash reduces it18.

    • Economic Activity: Booms expand supply (more borrowing); Recessions contract it19.

    • Balance of Payments: A Trade Surplus (Exports > Imports) increases supply via foreign exchange inflows20.


IV. Financial Intermediaries

  • Definition: Entities that mediate between savers (excess cash) and borrowers (need cash)21212121.

  • Key Functions:

    • Asset Storage: Safe storage of cash/metals; insured by bodies like FDIC22222222.

    • Risk Distribution: Spreads lending risk across multiple borrowers to minimize default impact23.

    • Economies of Scale: Lower transaction costs via bulk handling24.

    • Economies of Scope: Offering specialized services to different customer types25.

  • Specific Types:

    • Venture Capital: Financing for startups with long-term growth potential26.

    • Microfinance (MFIs): Small loans for under-served markets27.

    • Lease-Financing: Lessor (owner) grants use to Lessee (user) for rent; asset returns to owner at end 28.
