Q.1 Calculate the value money multiplier and the total deposit created if initial deposit is of Rs. 500 crores and LRR is 10%.
Ans: Money multiplier = 1 / LRR = 1 / 0.10 = 10.
Initial deposit = Rs. 500 crores.
Total deposits created = Initial deposit × Money multiplier.
= 500 × 10 = Rs. 5,000 crores.
This means, with a 10% reserve ratio, every rupee of the original deposit can support up to ten rupees of total bank deposits.
Q.2 If total deposits created by commercial banks are Rs.12000, LRR is 25% calculate initial deposit.
Ans: Money multiplier = 1 / LRR = 1 / 0.25 = 4.
Initial deposit = Total deposits / Money multiplier = 12,000 / 4 = Rs. 3,000 crores.
This shows that with a 25% reserve requirement, the total deposits are four times the primary (initial) deposit.
Q.3 Calculate LRR, if initial deposit of Rs. 200 crores leads to creation of total deposits of Rs. 1600 crores.
Ans: Money multiplier = Total deposits / Initial deposit = 1,600 / 200 = 8.
Money multiplier = 1 / LRR ⇒ 8 = 1 / LRR ⇒ LRR = 1 / 8 = 0.125 = 12.5%.
