Definition
The Statutory Liquidity Ratio (SLR) is the minimum percentage of a bank's Net Demand and Time Liabilities (NDTL) that must be maintained in specified liquid assets — principally Government of India dated securities (G-Secs), State Development Loans (SDLs), and Treasury Bills. SLR is mandated under Section 24 of the Banking Regulation Act, 1949, which empowers RBI to prescribe the ratio. Unlike CRR (held as cash with RBI earning zero), SLR securities are interest-bearing sovereign assets held in banks' own Held-to-Maturity (HTM) or Available-for-Sale (AFS) portfolios. The current SLR is 18% of NDTL. SLR has been on a long secular decline from a peak of 38.5% in 1991, as financial liberalisation reduced the government's captive financing requirement.
How It Operates
SLR compliance is measured on a daily basis (unlike CRR's fortnight average). Banks must hold approved securities equal to at least 18% of NDTL at close of business each day. Eligible assets include: (a) Cash (in excess of CRR), (b) Gold valued at current market price, and (c) Approved securities — primarily G-Secs, SDLs, and T-Bills. In practice, virtually all SLR compliance is met via G-Sec holdings; gold is minimal. The Marginal Standing Facility (MSF) allows banks to temporarily draw down SLR holdings up to 3% of NDTL for overnight borrowing from RBI at repo + 25 bps — effectively a liquidity buffer within SLR. Penalty for shortfall: 3% per annum above bank rate on the shortfall amount.
Why It Matters for Investors
- G-Sec demand anchor: Bank SLR mandates create a captive, price-insensitive buyer base for government securities, supporting G-Sec prices and keeping sovereign borrowing costs lower than pure market rates would imply.
- Credit-deposit ratio: Every percentage point of SLR means ~₹1.4 lakh crore locked in G-Secs rather than deployed as loans. SLR reductions historically accompany periods of credit growth and rising loan-to-deposit ratios.
- HTM buffer: Banks classify SLR holdings largely as HTM, shielding P&L from mark-to-market losses when rates rise — this reduces bank earnings volatility but creates hidden balance sheet risk.
- Gilt funds: When SLR is reduced, banks sell some G-Secs — increasing supply and pressuring yields. Gilt fund investors should monitor SLR policy during fiscal consolidation periods.
Current Value + Recent History
SLR has been at 18.00% since January 2020, when RBI reduced it from 18.25%. Before that, a series of 25 bps quarterly cuts had brought it down from 20.5% (mid-2017). The trajectory has been one of deliberate, gradual reduction — reflecting both fiscal consolidation (lower borrowing need as a captive demand) and a desire to free up bank credit for the private sector. As of early 2024, the aggregate SLR holdings of scheduled commercial banks are estimated at approximately ₹52–54 lakh crore — well above the minimum required, as many banks hold "excess SLR" as a safe, sovereign yield instrument in the absence of viable private credit demand.
Worked Example
Understanding the SLR-credit nexus through a hypothetical bank:
- Bank NDTL = ₹10,000 crore. CRR at 4.5% → ₹450 crore locked at RBI. SLR at 18% → ₹1,800 crore in G-Secs. Total locked: ₹2,250 crore (22.5% of NDTL).
- Available for lending: ₹10,000 – ₹2,250 = ₹7,750 crore (plus capital, minus regulatory buffers).
- If SLR cut 100 bps (to 17%): Frees up ₹100 crore per ₹10,000 crore NDTL. Across the system (NDTL ~₹200 lakh crore), a 100 bps SLR cut releases approximately ₹2 lakh crore of deployable funds — equivalent to ~4 months of incremental bank credit growth at current pace.
- G-Sec impact: If banks sell some of the freed SLR portfolio, 10Y G-Sec yield could widen 10–20 bps depending on RBI's OMO absorption.
