MONETARY AGGREGATES
These are measures of the money supply. We add
together all assets that are liquid enough to be classified
as money

M1The narrow measure of the money supply; includes only the most liquid assets
M1 equals Currency and coin in circulationPlus: Checkable depositsPlus: Travelers’ checks

About 60 percent of Federal Reserve
notes now circulate abroad

HOW BANKS WORKBy bringing together both sides of the money market , banks serve as intermediaries or go-betweens. Banks reduce the transactions costs of channeling saving to creditworthy borrowers.
•Coping with asymmetric information.•Reducing risk through diversification.

STARTING A BANK
To start a bank we must obtain a charter from a state government
or from the Federal Reserve

RESERVE REQUIREMENTSBanks must maintain a reserve account at the regional Federal Reserve bank
•Required reserves: The dollar amount of reserves a bank is required to hold as cash in vault or on account at the Fed.•Required reserve ratio: The ratio of reserves to deposits that banks by regulation are obligated to hold.•Excess reserves: Bank reserves exceeding required reserves
![Page 12: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/12.jpg)
LIQUIDITY VERSUS PROFITABILITY
Banks must be ready for customers’ withdrawals, so
liquid bank assets are desirable. At the same time,
less liquid assets such as commercial and real estate loans are more profitable.
![Page 13: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/13.jpg)
BANKS CREATE MONEY!!
•Banks create money when they make loans and credit the accounts of loan recipients.•Money creation (lending) is limited by banks’ holdings of excess reserves. •Reserve do not earn interest; hence banks seek to minimize reserve holdings
![Page 14: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/14.jpg)
ILLUSTRATING THE EFFECTS OF FED OPEN MARKET OPERATIONS
Suppose the Fed pays $1,000 to a securities dealer for a bond. The
transaction is handled by the dealer’s bank—Home
Bank
![Page 15: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/15.jpg)

Changes in Home Bank’s balance sheet after Fed buys a $1,000 bond from Securities dealer
Assets Liabilities Reserves at Fed +$1,000 Checkable deposits +$1,000
oThe Fed credits home Bank’s reserve account by $1,000.oHome Banks’ liabilities increase by $1,000.
![Page 16: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/16.jpg)
LET’S MAKE A LOAN!Assume the legal reserve ratio is .10 or 10 percent.
The preceding transaction will create a $900 excess reserve for Home Bank. Loans and
deposits can be expanded by that
amount.
![Page 17: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/17.jpg)

Round 2: Changes in Home Bank’s balance sheet after lending $900 to you
Assets Liabilities Loans +$900 Checkable deposits +$900
Thus the money supply initially increases by $900 as a result of this loan.
![Page 18: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/18.jpg)
CHECKING AWAY THE LOAN
1. Suppose you write a $900 check to your university to pay fees.
2. Your university deposits the check into its account at Merchants Trust bank.
3. When the check clears, the Fed debits Home Banks’ reserve account for $900 and credits Merchant Bank’s reserve account for $900.
4. Thus the transaction creates a $810 excess reserve for MerchantsTrust.
![Page 19: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/19.jpg)
MERCHANTS TRUST MAKES A LOANMerchants Trust makes a $810 loan
to an English major starting an online note-taking service called “Note
This.”
![Page 20: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/20.jpg)

Round 3: Changes in Merchants Trust’s balance sheet after lending $810 to English Major
Assets Liabilities Loans +$810 Checkable deposits +$810
Note that as a result of this loan the money supply has increased by $810.
![Page 21: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/21.jpg)
CHECKING AWAY THE LOAN: PART 2
1. The English major writes an $810 check to the college bookstore.
2. The college bookstore deposits the $810 check into its account at Fidelity Bank
3. When the check clears, the Fed debits Merchant Trust’s reserve account for $810 and credits Fidelity Bank’s reserve account for $810.
4. Thus the transaction creates a $729 excess reserve for Fidelity Bank.
![Page 22: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/22.jpg)
Fidelity Bank is now positioned to make loans totaling $729
![Page 23: Banking and the Money supply](https://reader035.fdocuments.in/reader035/viewer/2022062815/5681697c550346895de185f4/html5/thumbnails/23.jpg)

SIMPLE MONEY MULTIPLIER
The multiple by which the money supply changes as a result of a fresh change in fresh reserves of the banking system.
Change in the money supply = change in fresh reserves x 1/r
Where r is the required reserve ratio Simple money multiplier
In our case:
Change in the money supply = $900 x 1/.10 = (4900)(10)= 9,000

FED OPEN MARKET OPERATIONSHAVE POWERFUL EFFECTS
It should be clear now that when Fed buys
government securities in large quantities, there are strong effects in terms of bank excess reserves and
lending capacity.
