Bank 1 received a deposit of SR1 million. Assuming that the banks retain no excess reserves, answer the following questions:
The reserve requirement is 25 percent.
Fill in the blanks in the table below.
What is the deposit multiplier?
Multiple Deposit Creation
Round  | Deposits  | Reserves  | Loans  | 
Bank 1 Bank2 Bank3 Bank 4 Bank5 All other banks Totals  | SR1, 000,000  | SR  | SR  | 
Now the reserve requirement is 5 percent.
Fill in the blanks in the similar table.
What is the deposit multiplier?
Multiple Deposit Creation
Round  | Deposits  | Reserves  | Loans  | 
Bank 1 Bank2 Bank3 Bank 4 Bank5 All other banks Totals  | SR1, 000,000  | SR  | SR  | 
(i) Deposit multiplier is the number of times at which credit is created in the economy.
Deposit multiplier = 1/ (Required reserve ratio)
= 1/25%
= 4 times
| Round | Deposits | Reserves | Loans | 
| Bank 1 | SR 1000000 | 250000 | 750000 | 
| Bank 2 | 750000 | 187500 | 562500 | 
| Bank 3 | 562500 | 140625 | 421875 | 
| Bank 4 | 421875 | 105468.75 | 316406.25 | 
| Bank 5 | 316406 | 79101.56 | 237304.5 | 
| Total | 4,000,000 | 1,000,000 | 3,000,000 | 
(ii) if the reserve requirement is 5%
Multiplier = 1/5%
= 20 times
| Rounds | Deposits | Reserves | Loans | 
| Bank 1 | SR 1,000,000 | SR 50000 | SR 950000 | 
| Bank 2 | 950000 | 47500 | 902500 | 
| Bank 3 | 902500 | 45125 | 857375 | 
| Bank 4 | 857375 | 42868.75 | 814506.25 | 
| Bank 5 | 814507.25 | 40725.31 | 773781 |

 All other bank ( further 16 times) Total  | 
 15475617.75 20,000,000  | 
 773780.94 1000000  | 
 14701837.75 19000000  | 
This the credit creation process.
