CRR and SLR explained: the RBI's banking liquidity levers

What CRR and SLR require

Every bank holds deposits from the public, and it lends most of that money out, which is how banking works and how money multiplies through the economy. But it cannot lend all of it, because the RBI requires a cushion. The Cash Reserve Ratio is the slice of a bank's deposits it must keep with the RBI as plain cash, earning no interest. As of mid-2026 the CRR is 3.00%, so for every 100 rupees of deposits, 3 rupees sit idle at the central bank and cannot be lent. CRR is purely about safety and liquidity control, not about earning anything.

The Statutory Liquidity Ratio is a second, larger requirement. It is the slice of deposits a bank must hold in safe, liquid assets, predominantly government securities, but also gold and cash. As of mid-2026 the SLR is 18.00%. Unlike CRR, SLR assets do earn a return, since government bonds pay interest, but the bank still cannot use that portion for ordinary lending. SLR has a statutory ceiling of 40% under the Banking Regulation Act, well above where it actually sits, and it doubles as a way to ensure banks hold a buffer of government paper.

Why the RBI moves them

CRR and SLR are the quantity tools of monetary policy, sitting beside the repo rate, which is the price tool. When the RBI wants to tighten, to drain money from the system and cool inflation or credit, it can raise the CRR, which locks up more of every deposit at the central bank and leaves banks with less to lend. When it wants to ease, to free up money and support growth, it can cut the CRR, releasing cash into the banking system that banks can now lend out. A CRR change has a powerful, immediate effect on liquidity precisely because it is a blunt, system-wide lock.

These ratios are moved far less often than the repo rate, which is why a CRR or SLR change is a bigger event when it happens. The repo rate is the routine, bi-monthly dial; the reserve ratios are the heavier switches pulled when the RBI wants to shift the actual quantity of lendable money, not just its price. As of mid-2026 both were held steady, with CRR at 3.00% and SLR at 18.00% unchanged at the June review, which signals the RBI was managing the economy through the rate and liquidity operations rather than the reserve ratios.

How they reach bank stocks and the economy

For the wider economy, CRR and SLR set the ceiling on credit creation. The lower the reserve requirements, the more of each deposit a bank can lend, the faster credit can grow, and the more fuel there is for businesses to borrow and expand. The higher the requirements, the tighter the leash. So these ratios sit upstream of credit growth, which is one of the engines of GDP, which is why their moves ripple far beyond the banking sector.

For bank stocks specifically, the ratios touch profitability directly. CRR is the most punishing, because cash parked at the RBI earns nothing, so a high CRR is a drag on a bank's earnings, money it must hold but cannot put to work. A CRR cut is generally welcomed by bank shares because it frees idle cash to be deployed into interest-earning loans. SLR is gentler since those assets at least earn bond interest. An investor in banking and financial stocks watches the reserve ratios as closely as the repo rate, because together they decide both how much a bank can lend and how much of its deposit base is trapped earning little or nothing.
