SLR (Statutory Liquidity Ratio)

The Statutory Liquidity Ratio (SLR) is one of the RBI's core tools for keeping the banking system safe and for managing how much money flows into the economy. It is the minimum percentage of a bank's Net Demand and Time Liabilities (NDTL), essentially its deposits, that the bank must hold in approved liquid assets.

How it works

Those approved assets are mainly government securities (G-Secs and SDLs), cash and gold. The idea is simple: before a bank lends out depositors' money, it must keep a cushion of high-quality, easily sellable assets so it can always meet withdrawal demands.

The RBI sets the rate. The SLR has been held at 18% of NDTL in recent policy, though the RBI is legally empowered to set it anywhere up to 40%. SLR is different from the CRR (Cash Reserve Ratio), which is the slice banks must keep as plain cash with the RBI earning no interest; SLR assets like G-Secs do earn a return.

In India

For decades the SLR ensured a captive demand for government bonds, banks had to buy G-Secs to meet it. That demand helps the Centre and states fund their borrowing, which is why SLR is tied closely to the G-Sec and SDL market that debt mutual funds invest in.

Why it matters for fund investors

Indirectly, the SLR shapes the bond market your debt funds live in. Banks usually hold G-Secs well beyond the mandatory SLR floor, so changes in SLR, or in how SLR holdings are valued, can affect demand for government bonds and therefore their yields and prices.

When the RBI tweaks SLR or its liquidity stance, it influences interest rates across the curve, which feeds straight into the NAVs of gilt funds, dynamic bond funds and target-maturity funds.

The practical takeaway: you will not transact in SLR, but it is part of the plumbing. A stable, well-capitalised banking system and a deep G-Sec market, both supported by the SLR framework, are what make Indian debt funds reasonably safe and liquid.
