Fractional Reserve Lending ..... You would go to jail if you did this ....
How It Works
John Doe decides that he is going to deposit in the bank the sum of $100 dollars. The bank gladly takes the $100 dollars from Mr. Doe, and in return gives him a receipt (passbook) that states that the bank owes him $100 dollars.
If you read the fine print on any deposit agreement you sign with the bank, you will notice that you have actually loaned your money to the bank. In return you get an i.o.u. from the bank (deposit receipt or passbook), which stipulates the principal owed to you, and an amount of interest to be paid to you for the loan of money you just made to the bank. For simplicity, let us say you are paid 1% interest.
The bank has a 10% reserve requirement that means that on the $100 dollars you just loaned to them, they only have to keep on reserve 10% x $100 = $10 dollars. That leaves them $90 dollars to loan out to someone else.
When they loan out the $90 they have to keep on reserve 10% x 90 = $9 on reserve. They then can loan out $82.
Now stop and think about it. You "loaned" the bank $100. In two loan transactions subsequent to your "deposit" the bank has already loaned out $90 + $82 = $172 dollars.
By the use of fractional reserve lending, the bank has already loaned out $172 dollars using your $100.00 dollars.
So where do they get the extra $72 dollars to loan out. They do not get it from anywhere's - they just create it out of thin air as entries on a ledger. The money does not actually exist.
Granny Smith comes into the bank and wants to take out a loan for $90 dollars. No problem says the bank; John Doe just deposited $100 so we have plenty of money to lend you. Granny gets a loan for $90, and a loan agreement that says she owes the bank $90 dollars plus interest of 3% percent.
What this means is that the bank owes John Doe the $100 dollars he deposited with them, yet they only have $10 dollars on reserve, as they have lent the other $90 dollars to Granny Smith. How can the bank possibly meet its obligations?
Solvent Versus Liquid
As long as no more than 10% percent of all total depositors demand their money at any one time the bank remains solvent, as in aggregate they have that amount held in reserve. This is the dark side of fractional reserve lending: the seamy side - the moral hazard that borders on fraud.
If a number of depositors greater than the 10% held in reserve demand their money at the same time, the bank will be in a bit of a bind, as they do not have that amount of money on deposit. They will have to call the Fed as the lender of last resort.
The Fed will have no problem in supplying the money - as long as no more than 10% of the total of ALL DEPOSITORS in the banking system don't want their money at the same time, because if they do - it ain't there. This is a banker's worst nightmare - it's called a run on the banks.
