Learning Objectives

  • List and describe the “three players” that influence the money supply.

  • Classify the factors affecting the Federal Reserve’s assets and liabilities.

  • Identify the factors that affect the monetary base and discuss their effects on the Federal Reserve’s balance sheet.

  • Explain and illustrate the deposit creation process using T-accounts.

  • Summarize how the “three players” can influence the money supply.

  • Calculate and interpret changes in the money multiplier.

Three Players in the Money Supply Process

  1. The Central Bank: Federal Reserve System

  2. Banks: Depository institutions; financial intermediaries

  3. Depositors: Individuals and institutions

The Fed’s Balance Sheet

  • Assets

    • Securities: Holdings by the Fed that affect the money supply and earn interest.

    • Loans to Financial Institutions: Provide reserves to banks and earn the discount rate.

  • Liabilities

    • Currency in circulation: Money in the hands of the public.

    • Reserves: Bank deposits at the Fed and vault cash.

Control of the Monetary Base

  • Formula: R = MB = C + R

    • C = currency in circulation

    • R = total reserves in the banking system

Open Market Operations

1. Open Market Purchase from a Bank
  • Bank's Assets and Liabilities:

    • Securities decrease by $100m

    • Reserves increase by $100m

  • Federal Reserve's Balance Sheet:

    • Securities increase by $100m

    • Reserves increase by $100m

  • Result: Reserves increased by $100m, Monetary Base has risen by $100.

2. Open Market Purchase from the Nonbank Public
  • Nonbank Public's Balance Sheet:

    • Assets: Securities decrease by $100m

    • Currency increases by $100m

  • Federal Reserve's Balance Sheet:

    • Securities increase by $100m

    • Reserves increase by $100m

  • Result: Monetary Base has risen by $100 million.

3. Open Market Sale to Nonbank Public
  • Nonbank Public's Balance Sheet:

    • Assets: Securities increase by $100m

    • Currency decreases by $100m

  • Federal Reserve's Balance Sheet:

    • Securities decrease by $100m

    • Currency in circulation decreases by $100m

  • Result: Monetary Base reduced by the amount of the sale; reserves remain unchanged.

Total Reserves

1. Required Reserves
  • Definition: Amount of funds that a bank is required to hold in reserve to meet liabilities.

2. Excess Reserves
  • Definition: Funds held by a bank that exceed the required minimum, which can be used for loans or investments.

Assessment Examples

  1. Problem: Excess Reserves Calculation

    • Given vault cash, deposits at the Fed, and required reserves, calculate excess reserves for First National Bank.

  2. Problem: Required Reserve Ratio Calculation

    • Given vault cash, excess reserves, and demand deposits, calculate amount on deposit with the Federal Reserve.

Summary of Open Market Purchase Effects

  • Open market purchases increase monetary base:

    • Effect depending on whether bond proceeds remain in currency or in deposits.

    • However, universally increases the monetary base by the amount of purchase.--

Other Monetary Base Factors

  • Float: Temporary imbalance in the Federal Reserve’s balance sheet due to check processing delays.

  • Treasury Deposits: Affect the money supply by changing reserves when the Treasury Department holds or releases cash.

  • Foreign Exchange Market Interventions: Buying/selling foreign currency affects the monetary base.

Monetary Base Control by the Fed

  • Components of Monetary Base:

    • MB_n = MB - BR

  • Relationship: Money supply is positively related to non-borrowed monetary base MB_n and borrowed reserves BR .

Multiple Deposit Creation: A Simple Model

Deposit Creation Process
  • T-account structure for banks showing how deposits are impacted by reserve changes. Example:

    1. Bank Assets: Reserves increase by $100m.

    2. Liabilities: Required reserves adjusted accordingly.

    3. Subsequent banks receive part of this in loans and maintain required reserves leading to further deposit creation.

Theory Behind Deposit Creation
  • Initial increase in reserves leads to multiplication through a defined reserve ratio.

    • For example, with a 10% reserve requirement and a $100 increase in reserves, deposits can increase significantly across multiple banks.

Critique of the Simple Model

  1. Cash Holdings: Holding cash stops the deposit expansion process because currency does not contribute to bank reserves.

  2. Excess Reserves Utilization: Banks might not utilize all excess reserves to issue loans.

  3. Behavioral Factors: The decisions of depositors and banks regarding reserves heavily influence money supply.

Factors Determining Money Supply

  1. Changes in Non-borrowed Monetary Base: Directly impacts money supply positively.

  2. Changes in Borrowed Reserves from the Fed: Positive correlation to money supply as institutions borrow more.

  3. Required Reserves Ratio: Higher ratios negatively relate, reducing multiple deposit expansion capabilities.

  4. Currency Holdings Changes: Increased currency holdings negatively impact the money supply.

  5. Excess Reserves Changes: Increased excess reserves result in lower money creation through loans.

Overview of Money Supply Process

Player

Variable

Change in Variable

Money Supply Response

Reason

Federal Reserve System

Nonborrowed monetary base, MBn

More MB for deposit creation

Required reserve ratio, rr

Less multiple deposit expansion

Banks

Borrowed reserves, BR

More MB for deposit creation

Excess reserves

Less loans and deposit creation

Depositors

Currency holdings

Less multiple deposit expansion

M1 Money Multiplier

  • Definition:

    • Money Supply (M1) is defined as the sum of currency and checkable deposits.

  • Formula:

  • M = m imes MB

    • Where m is the money multiplier.

Deriving the M1 Money Multiplier
  1. Currency and Excess Reserves Relationship:

    • Define ratios:

    • Currency Ratio: c = rac{C}{D}

    • Excess Reserves Ratio: e = rac{ER}{D}

  2. Total Reserves Calculation:

    • R = RR + ER

    • Where RR = r imes D (with r being the required reserve ratio).

  3. Monetary Base Formula:

    • MB = C + R = C + (r imes D) + ER

Assessment on Reserve Ratio Effects

  • Change in required reserve ratio leads to effects in the size of the multiplier and thus the calculations of overall money supply variations.

  • Example: If the required reserve ratio is decreased, it leads to a potential increase in money multiplier based on stable currency-to-deposit and excess-reserve ratios.

Quantitative Easing and the Money Supply, 2007–2017

  • Context: Following the 2007 global financial crisis, the Fed initiated various lending and asset-purchase programs aimed at stabilizing the economy.

  • Result: By late 2017, asset purchases led to a quintupling of the Fed's balance sheet and a 350% increase in the monetary base.
