Answer:
Required Reserves
Step-by-step explanation:
Fractional banking is a banking system where a portion of customer's deposits is kept as reserves while remaining portion is lent out. The amount kept as reserves is determined by the required reserve ratio set by the Central bank.
Reserves is the total amount of a bank's deposit that is not given out as loans
Reserves = Deposits - outstanding loans
$100,000 - $70,000 = $30,000
there are 2 types of reserves
1. Required reserves is the percentage of deposits required of banks to keep as reserves by the central bank
Required reserves = reserve requirement x deposits
0.2 x $100,000 = $20,000
2. Excess reserves is the difference between reserves and required reserves
$30,000 - $20,000 = $10,000
