To determine the size of ABC Bank's actual reserves, we can use the following formula:
\[ \text{Actual Reserves} = \text{Required Reserves} + \text{Excess Reserves} \]
First, we need to calculate the required reserves:
- The reserve requirement is 25% of the outstanding cheque deposits.
Given that the outstanding cheque deposits are R80,000:
\[ \text{Required Reserves} = \text{Reserve Requirement} \times \text{Outstanding Cheque Deposits} \] \[ \text{Required Reserves} = 0.25 \times R80,000 = R20,000 \]
Now we can find the actual reserves:
Using the earlier formula:
- Excess Reserves = R4,000
So, we can substitute:
\[ \text{Actual Reserves} = R20,000 + R4,000 = R24,000 \]
Therefore, the size of the bank's actual reserves is R24,000.
