suppose we have a banking system in which the public chooses to make all of its purchases by using checking deposits. in addition, banks desire to maximize the reserve ratio is 20% and the FED purchases $1,000,000 in treasury bills from bank 1. explain what happens to this bank (Bank 1) and two additional steps in the deposit expansion process based on the 20% reserve requirement. Put differently, what will be the change in deposits for the first bank (Bank1) the second bank (Bank 2) and the third bank (Bank 3)
Bank1:
Increase in reserve = $1000000
Decrease in treasury bills = $1000000
Change in deposits = No change
Change in total assets = No change
Change in total liability = No change
Now $1000000 will be issued as loans.
Bank 2:
Increase in Deposit = $1000000
Increase in required reserve = 1000000*20% = $200000
Increase in Excess Reserve = 1000000*(1-20%) = $800000
Now, $800000 will be issued as loans.
Bank 3:
Increase in Deposit = $800000
Increase in required reserve = 800000*20% = $160000
Increase in excess reserve = 800000*(1-20%) = $640000
Now, $640000 will be issued as loans.
