Q.What is meant by credit creation? Explain the role of the Cash Reserve Ratio in the process.

Banks can lend out more money in total than any single deposit they receive, because only a fraction of each deposit must be kept in reserve.

Credit creation is the process by which commercial banks, taken together as a system, expand the total volume of money supply well beyond the cash originally deposited with them. It rests on the fractional reserve system: a bank is required to keep only a fraction of every deposit — the Cash Reserve Ratio (CRR) — as reserve with the RBI, and is free to lend out the rest. When a borrower spends a loan and the recipient redeposits it, the receiving bank again keeps only the CRR fraction as reserve and lends the remainder, and this cycle repeats in progressively smaller rounds.

The CRR directly determines how large the resulting expansion is, through the credit multiplier:

$\text{Total Credit Creation} = \text{Initial Deposit} \times \frac{1}{\text{CRR}}$ …

Describing credit creation as something a SINGLE bank does on its own — the multiple expansion happens across the banking SYSTEM as a whole, as money is repeatedly redeposi …
