5. 5 What Gives Money its Value? Our money has value because the government “says” it has value. Our money has value because the government “says” it has value. We accept paper dollars because we know that other people will accept dollars later when we try to spend them.

10. What’s with All the Currency?  $775.4 billion of currency in circulation. That’s $2,570 in cash for every man, woman, and child in the United States. How many people do you know who carry $2,570 in their wallets? Not many. So where is all that cash? Part of the answer is that it isn’t in individuals’ wallets: it’s in cash registers.  Economists also believe that cash plays an important role in transactions that people want to keep hidden. Small businesses and the self-employed sometimes prefer to be paid in cash so they can avoid paying taxes by hiding income from the Internal Revenue Service.  The most important reason for those huge currency holdings, however, is foreign use of dollars. The Federal Reserve estimates that 60% of U.S. currency is actually held outside the United States.

11. The Banking System There was a wave of bank runs in the early 1930s. To bring the panic to an end Franklin Delano Roosevelt declared a national “bank holiday,” closing all banks for a week to give bank regulators time to close unhealthy banks and certify healthy ones.

Since then, regulation has protected the United States and other wealthy countries against most bank runs. Since then, regulation has protected the United States and other wealthy countries against most bank runs. There are some limits on deposit insurance; in particular, currently only the first $250,000 of any bank account is insured. As a result, there can still be a rush out of a bank perceived as troubled.

13. 13 Balance Sheet for a Commercial Bank Reserves are assets that are not lent out. Reserves are assets that are not lent out. Required reserves are the fraction of banks’ deposits they are legally required to hold in their vaults or as deposits at the Fed. Required reserves are the fraction of banks’ deposits they are legally required to hold in their vaults or as deposits at the Fed. Excess reserves are any additional reserves that a bank chooses to hold beyond what is required. Excess reserves are any additional reserves that a bank chooses to hold beyond what is required. Excess + Required Reserves = Total Reserves Excess + Required Reserves = Total Reserves When a customer makes a cash deposit, the bank’s reserves increase. Since the currency held by the public decreases but checking deposits increase, the money supply remains unchanged. When a customer makes a cash deposit, the bank’s reserves increase. Since the currency held by the public decreases but checking deposits increase, the money supply remains unchanged.

14. 14 How Banks Create Money ? Let’s assume that banks are required to keep 10% of their deposits as required reserves. The required reserved ratio is the ratio of reserves a bank must retain based upon its deposits. After a customer makes a $1,000 deposit, the bank’s balance sheet changes as follows, assuming they loan out their new excess reserves.: Let’s assume that banks are required to keep 10% of their deposits as required reserves.

After a customer makes a $1,000 deposit, the bank’s balance sheet changes as follows, assuming they loan out their new excess reserves.:

15. 15 The Process of Money Creation First Bank of Hollywood makes a $900 loan which is used to open a checking account in the Second Bank of Burbank, with a balance of $900. First Bank of Hollywood makes a $900 loan which is used to open a checking account in the Second Bank of Burbank, with a balance of $900. The Second bank of Burbank makes loans in the amount of $810, which are deposited in the Third Bank of Venice, and so on. The Second bank of Burbank makes loans in the amount of $810, which are deposited in the Third Bank of Venice, and so on.

16. 16 The Process of Money Creation —next slide The increase in the money supply, M1, resulting from the increase in the $1,000 deposit equals $10,000 - $1,000 = $9,000.—next slide

17. 17 How the Money Multiplier Works The original $1,000 cash deposit has created checking account balances equal to: The original $1,000 cash deposit has created checking account balances equal to: $1,000 + $900 + $810 + $729 + $656.10 +.…= $10,000 The general formula for deposit creation is: The general formula for deposit creation is: The increase in the money supply, M1, resulting from the increase in the $1,000 deposit equals $10,000 - $1,000 = $9,000. Increase in checking account balances = 1/0.1 x 1000 = 10 x 1000 = $10,000

18. 18 How the Money Multiplier Works The money multiplier shows the total increase in checking account deposits for any initial cash deposit. The formula for the multiplier is: The money multiplier shows the total increase in checking account deposits for any initial cash deposit. The formula for the multiplier is: The initial cash deposit triggers additional rounds of deposits and lending by banks, which leads to a multiple expansion of deposits. The initial cash deposit triggers additional rounds of deposits and lending by banks, which leads to a multiple expansion of deposits.

19. 19 How the Money Multiplier Works Assumptions: All monies were deposited in bank checking accounts. All monies were deposited in bank checking accounts. Every bank lent all its excess reserves, leaving every bank with zero excess reserves. Every bank lent all its excess reserves, leaving every bank with zero excess reserves. Because we assumed no cash leakages and zero excess reserves, the change in checkable deposits (increase in money supply) is the maximum possible change. Because we assumed no cash leakages and zero excess reserves, the change in checkable deposits (increase in money supply) is the maximum possible change.

20. 20 How the Money Multiplier Works in Reverse The money multiplier also works in reverse. Assuming a reserve ratio of 10%, a withdrawal of $1,000 reduces reserves by $100, and results in $900 less the bank will have to lend out. The money multiplier also works in reverse. Assuming a reserve ratio of 10%, a withdrawal of $1,000 reduces reserves by $100, and results in $900 less the bank will have to lend out. It is important to note that when one individual writes a check to another, and the other deposits the check in the bank, the money supply will not change. Instead, the expansion in one bank’s reserves will offset the contraction in the reserves of the other. It is important to note that when one individual writes a check to another, and the other deposits the check in the bank, the money supply will not change. Instead, the expansion in one bank’s reserves will offset the contraction in the reserves of the other. Likewise if cash is deposited into a checking account, the money supply (M1) will not change. Likewise if cash is deposited into a checking account, the money supply (M1) will not change.

26. 26 Interest Rates and Bond Prices Bonds are promises to pay money in the future. Bonds are loans. The price of a bond one year from now is the promised payment divided by 1 plus the interest rate. Bonds are promises to pay money in the future. Bonds are loans. The price of a bond one year from now is the promised payment divided by 1 plus the interest rate. For example, a bond that promises to pay $106 a year, with an interest rate is 6% per year, would cost today: For example, a bond that promises to pay $106 a year, with an interest rate is 6% per year, would cost today: In other words, if you can invest at 6% per year, you would be willing to pay $100 today for a promised payment of $106 next year.

27. 27 Bond prices change in the opposite direction of interest rates When the interest rate falls from 6% to 4%, you have to pay $101.92 today to have $106 next year. And if the interest rate rose to 8%, for example, you would pay only $98.15.When the interest rate falls from 6% to 4%, you have to pay $101.92 today to have $106 next year.

28. 28 How Bond Prices Affect Money Supply If money supply decreases; interest rates increase; people sell bonds to get money; # of bonds increase; cost of bonds decrease and the lower cost creates a higher yield If money supply decreases; interest rates increase; people sell bonds to get money; # of bonds increase; cost of bonds decrease and the lower cost creates a higher yield Banks increase interest rates to compete with bonds; higher interest rates leads to higher deposits/savings Banks increase interest rates to compete with bonds; higher interest rates leads to higher deposits/savings This process is reversed if money supply increases This process is reversed if money supply increases
