Statutory Liquidity Ratio (SLR) is defined as the proportion of a bank's total demand and time liabilities that must be held as liquid assets. These liquid assets include cash, gold, or authorized government securities (bonds).
The SLR mandates banks to hold sufficient liquid assets to address unexpected depositor withdrawals and to control credit expansion.
Before disbursing credit to clients, banks must retain this mandated proportion, rather than lending it out.
In contrast, the Cash Reserve Ratio (CRR) is a reserve held entirely in cash with the RBI, unlike the SLR which involves securities such as bonds.
Repo Rate and Reverse Repo Rate are interest rates governing borrowing and lending between banks and the RBI, and are not reserve ratios.
Consequently, option (D) SLR Rate is accurate because it specifically designates the mandatory securities reserve requirement prior to lending operations.
