The ratio of liquid assets to demand and time liabilities maintained by banks in India is known as the Statutory Liquidity Ratio (SLR).
Besides Cash Reserve Ratio (CRR), banks are mandated to hold liquid assets such as gold, cash, and approved securities.
A higher SLR forces banks to hold a greater proportion of their resources in liquid assets, thereby reducing their lending capacity. This has an anti-inflationary effect.
It also channels funds away from loans towards government and approved securities, influencing the structure of public sector financing.
During the 1980s, the RBI increased the SLR to regulate liquidity and support public sector investment without creating reserve money.
In October 1981, SLR was increased from 34% to 35% in two phases.
From the fortnight beginning April 25, 1987, SLR was further raised to 37.5% of net demand and time liabilities.
Due to a surge in reserve money and falling food credit in December 1987, SLR was increased again to 38% starting January 2, 1988, to moderate liquidity while maintaining productive credit flow.
On October 16, 1993, the incremental SLR requirement was reduced from 30% to 25% for additional liabilities over the September 17, 1993 base level.
SLR was fixed at 34.75% for liabilities based on April 3, 1992 and September 17, 1993.
Effective October 14, 1995, banks were required to adopt a uniform system for valuing SLR securities for both SLR and balance sheet purposes.
From April 13, 1996, SLR on Non-Resident (External) Account (NRE) liabilities was reduced from 30% to 25% to rationalize overall SLR requirements.
From October 25, 1997, all scheduled commercial banks were mandated to maintain a uniform SLR of 25% on their net demand and time liabilities, the minimum required under Section 24 of the Banking Regulation Act, 1949.
The current SLR rate is 24%.
The key goal of SLR is to control the expansion of bank credit by regulating the proportion of liquid assets banks must maintain.
By adjusting the SLR, the RBI can influence credit creation by commercial banks and control inflation.
SLR helps ensure the solvency of banks by requiring them to hold safer assets such as government bonds.
The policy also compels banks to invest in government securities, aiding public borrowing and fiscal stability.
The RBI may raise SLR to curb excess liquidity and safeguard depositors' funds during inflationary phases.
