2 Minute Summary
CRR and SLR are two of the RBI's oldest tools for controlling how much money banks can actually lend out, and small changes to either ripple through interest rates across the entire economy.
The Cash Reserve Ratio (CRR) is the percentage of a bank's total deposits that it must keep with the RBI in cash, earning no interest. If CRR is 4%, a bank holding 100 crore in deposits must park 4 crore with the RBI untouched.
The Statutory Liquidity Ratio (SLR) is similar in spirit but different in form - banks must hold a percentage of deposits in approved safe assets like government bonds, not cash. This gives banks a modest return while ensuring they hold a buffer of highly liquid, low-risk securities.
Both ratios shrink the pool of money available for banks to lend out. Raise CRR or SLR, and banks have less to lend, which tightens credit and tends to push interest rates up. Lower them, and banks suddenly have more room to lend, loosening credit conditions.
The RBI uses these levers alongside the repo rate to manage inflation and liquidity in the banking system - CRR and SLR changes are less frequent than repo rate changes but tend to have a broader, more structural effect on how much banks can lend overall.
Why It Matters
CRR and SLR changes quietly shape how easy or hard it is to get a loan, long before that shows up as a headline interest rate change.
Who Benefits
Savers and lenders benefit when RBI raises these ratios, as tighter liquidity often means better deposit rates in the medium term.
Who Is Impacted
Borrowers feel it first - a CRR or SLR hike typically means loans get costlier and harder to get as banks have less lendable money on hand.
Key Takeaways
- ✓CRR is the share of deposits banks must hold as cash with the RBI, earning no interest.
- ✓SLR is the share banks must hold in safe assets like government bonds.
- ✓Raising either ratio tightens how much banks can lend; lowering them loosens it.
