All rights reserved Introduction Smart cards permit people to use digital cash, which consists of funds contained in software programs called digital algorithms. By the time you finish this chapter, you will understand how the use of digital cash may affect the quantity of money in circulation.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Did You Know That… Through actions initiated by a central bank such as the Federal Reserve, depository institutions together create money? In this chapter, we shall examine the money multiplier process, which explains how an injection of new money into the banking system leads to an eventual multiple expansion in the total money supply.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Links Between Changes in the Money Supply and Other Economic Variables There are links between changes in the money supply and changes in GDP. There are links between changes in the money supply and the rate of inflation.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Links Between Changes in the Money Supply and Other Economic Variables (cont'd) Fractional Reserve Banking  A system in which depository institutions hold reserves that are less than the amount of deposits  Originated when goldsmiths issued notes that exceeded the value of gold and silver on hand

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves What do you think?  Can banks pay off all of their depositors?  How is it possible that they can pay them off eventually but not pay them off simultaneously?

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) In a fractional reserve banking system, banks do not keep sufficient reserves on hand to cover 100% of their depositors' accounts. There are three distinguishable types of reserves: legal, required and excess.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Reserves  In the U.S. Federal Reserve System, deposits held by Federal Reserve district banks for depository institutions, plus depository institutions’ vault cash

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Legal Reserves  Anything that the law permits banks to claim as reserves—for example, deposits held at Federal Reserve district banks and vault cash

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Required Reserves  The value of reserves that a depository institution must hold in the form of vault cash or deposits with the Fed

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Question  Do banks set their own reserve rate? Answer  No, the Federal Reserve sets the reserve requirement  Currently it is 10% on most transactions deposits

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Required Reserve Ratio  The percentage of total transactions deposits that the Fed requires depository institutions to hold in the form of vault cash or deposits with the Fed Required reserves = Transactions deposits  Required reserve ratio

Copyright © 2008 Pearson Addison Wesley. All rights reserved Depository Institution Reserves (cont'd) Excess Reserves  The difference between legal reserves and required reserves Excess reserves = Legal reserves – Required reserves

Copyright © 2008 Pearson Addison Wesley. All rights reserved The Relationship Between Legal Reserves and Total Deposits (cont'd) We assume 1. Reserve ratio is 10% 2. Transactions deposits are the bank’s only liabilities and loans are the bank’s assets 3. An individual bank can lend as much as legally allowed 4. Every time a loan is made, the proceeds are put into a deposit account (nothing withdrawn) 5. Zero excess reserves are kept 6. Banks have zero net worth

Copyright © 2008 Pearson Addison Wesley. All rights reserved The Relationship Between Legal Reserves and Total Deposits (cont'd) Net Worth  The difference between assets and liabilities

All rights reserved The Relationship Between Legal Reserves and Total Deposits (cont'd) Effect on the money supply  New reserves for the banking system as a whole are not created when debit-card or check payments are transferred from one bank and deposited in another bank.  The Federal Reserve System can however, create new reserves—the subject of our next section.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Money Expansion by the Banking System Consider the entire banking system; for practical purposes, we can look at all depository institutions taken as a whole. To understand how money is created, we must understand how depository institutions respond to Fed actions that increase reserves in the entire system.

Copyright © 2008 Pearson Addison Wesley. All rights reserved Money Expansion by the Banking System (cont'd) Only when additional new reserves and deposits are created by the Federal Reserve System does the money supply increase.

Copyright © 2008 Pearson Addison Wesley. All rights reserved The Money Multiplier (cont'd) Actual change in the money supply = Actual money multiplier Change in total reserves  Potential money multiplier = 1 Required reserve ratio

Copyright © 2008 Pearson Addison Wesley. All rights reserved The Money Multiplier (cont'd) Example  Fed buys $100,000 of government securities  Reserve ratio = 10% Potential change in the money supply = $100,000 = $1,000,000 x 1.10

All rights reserved Sweep Accounts and the Decreased Relevance of Reserve Requirements (cont'd) Sweep Account  A depository institution account that entails regular shifts of funds from transactions deposits that are subject to reserve requirements to savings deposits that are exempt from reserve requirements

Copyright © 2008 Pearson Addison Wesley. All rights reserved Sweep Accounts and the Decreased Relevance of Reserve Requirements (cont'd) Banks use sweep accounts to shift funds from checking accounts into savings accounts until they are needed to settle check payments. Consequently, more of money supply growth has been shifted to M2, and M1 is considered a less reliable indicator of total liquidity.
