CRR vs SLR vs Repo Rate: How RBI’s Policy Tools Control Money and Credit — Banking Awareness Notes for SSC, UPSC & Banking Exams

Direct Answer: CRR vs SLR vs Repo Rate in One Paragraph

Quick answer: CRR is the percentage of a bank’s Net Demand and Time Liabilities (NDTL) that must be kept as cash with the RBI (earning no interest); SLR is the percentage of NDTL that banks must hold themselves as cash, gold, and approved securities (earning a return); the repo rate is the rate at which the RBI lends short-term money to banks against government securities. Raising CRR or SLR sucks lendable funds out of banks and tightens money supply; raising the repo rate makes bank borrowing costlier, pushing loan rates and EMIs upward. Together, these three quantitative tools let the RBI control liquidity, credit, and inflation.

Why RBI Needs Policy Tools: The Money Supply Objective

The Reserve Bank of India is the monetary authority of India under the RBI Act, 1934. Its core mandate is price stability while keeping credit flow supportive of growth. Since 2016, the RBI has followed flexible inflation targeting (4% CPI, ±2% band) under the amended RBI Act, with the Monetary Policy Committee (MPC) setting the policy repo rate bi-monthly. To steer money supply and credit, the RBI uses quantitative instruments (CRR, SLR, repo, reverse repo, bank rate, OMOs) and qualitative instruments (margin requirements, credit ceilings, moral suasion).

CRR (Cash Reserve Ratio) Explained

CRR is mandated under Section 42 of the RBI Act, 1934. Every scheduled bank must maintain a certain percentage of its NDTL as cash balances with the RBI. Key exam points:

• Banks earn no interest on CRR balances.
• Maintenance is calculated on a fortnightly average basis.
• When CRR rises, banks park more money with the RBI — lendable funds shrink instantly, tightening money supply.
• CRR is a blunt liquidity tool; it is rarely changed and only for major liquidity management.

SLR (Statutory Liquidity Ratio) Explained

SLR is mandated under Section 24 of the Banking Regulation Act, 1949. Banks must maintain a percentage of NDTL in cash, gold, and approved securities (mainly government bonds) held by the bank itself. Key exam points:

• Unlike CRR, SLR assets earn a return (interest on bonds, appreciation on gold).
• SLR holdings serve as a safety cushion and support government borrowing.
• Raising SLR reduces banks’ lendable resources; cutting SLR frees funds for credit.
• SLR also determines banks’ eligibility to access RBI lending windows.

Repo Rate and Reverse Repo Rate Explained

The repo rate is the rate at which the RBI lends overnight liquidity to banks against government securities under the Liquidity Adjustment Facility (LAF). The reverse repo was the rate at which the RBI absorbed liquidity by borrowing from banks; since April 2022, the Standing Deposit Facility (SDF) — which requires no collateral — is the floor of the liquidity corridor, with the Marginal Standing Facility (MSF) as the ceiling (corridor: repo ±25 basis points). The repo rate is the single policy rate decided by the six-member MPC.

The Transmission Mechanism: How Policy Rates Reach the Common Borrower

1. MPC changes the repo rate — say, raises it by 25 bps to fight inflation.
2. Bank funding costs rise — borrowing from RBI and short-term market borrowing gets costlier.
3. Banks reprice lending rates — computed on MCLR (Marginal Cost of funds based Lending Rate) or external benchmarks like the repo rate for new retail loans.
4. EMIs rise; credit demand falls — borrowers postpone loans, businesses cut expansion, money supply growth slows.
5. Inflation cools over 3–4 quarters as demand moderates — this lag is called the transmission lag.

Answering a common question — how does the repo rate affect loan EMIs? — a repo hike makes loans costlier, raising EMIs on floating-rate loans; a repo cut lowers them.

Quantitative vs Qualitative Tools of Monetary Policy

• Quantitative (general) tools affect total money/credit: CRR, SLR, repo/reverse repo, bank rate, open market operations (OMOs).
• Qualitative (selective) tools direct where credit flows: margin requirements, credit rationing/ceilings, moral suasion, direct action, publicity.

Exam one-liner: CRR, SLR, and repo are quantitative instruments — they control the volume of credit, not its purpose.

Past Exam Questions: SSC, UPSC & Banking PYQs on CRR, SLR, Repo

1. (SSC CGL) CRR is maintained by banks in the form of — cash with RBI. CRR is cash held with RBI, not with the bank.
2. (SSC) SLR is fixed under which Act? — Banking Regulation Act, 1949 (Section 24).
3. (UPSC Prelims 2013) Priority sector lending, SLR, CRR — which are quantitative/selective? SLR and CRR are quantitative; priority sector lending is selective/qualitative.
4. (IBPS PO) Interest paid by RBI on CRR balances? — Nil. Banks earn zero on CRR.
5. (IBPS Clerk) Repo rate is the rate at which — RBI lends to banks against government securities under LAF.
6. (SBI PO) An increase in CRR by RBI will — reduce banks’ lendable resources and contract money supply.
7. (RRB) Which tool is collateral-free for absorbing liquidity? — Standing Deposit Facility (SDF).

Memory Tricks and Common Confusions

• C = Cash, C = RBI’s Counter, C = No Commission (zero interest).
• S = Securities, S = Stored with the bank itself, S = Salary (earns return).
• Direction confusion: repo rate up = loans costlier = money supply down. Never mix the direction — the repo rate moves opposite to money supply.
• CRR works on quantity of funds; repo works on the price of funds.

Quick Revision Points and Expected Exam Questions

• CRR: Section 42, RBI Act 1934; cash with RBI; no interest; fortnightly maintenance; % of NDTL.
• SLR: Section 24, BR Act 1949; cash + gold + approved securities with bank; earns return.
• Repo: MPC-decided policy rate under LAF; corridor bounded by SDF (floor) and MSF (ceiling).
• All three are quantitative tools of monetary policy.

Practice MCQs:

1. If RBI cuts SLR by 1%, banks’ lendable resources will — increase.
2. The rate at which RBI absorbs liquidity without collateral is — SDF.
3. Which one of the following earns a return for banks: CRR / SLR / both? — SLR only.
4. The repo rate in India is decided by — the six-member MPC headed by the RBI Governor.

Frequently Asked Questions

Q: Does RBI pay interest on CRR?

No. Banks earn zero interest on CRR balances maintained with the RBI — that is why CRR directly drains banks’ earning capacity.

Q: Can SLR be maintained in gold and cash?

Yes. SLR includes cash, gold, and approved securities held by the bank itself.

Q: Who decides the repo rate in India?

The six-member Monetary Policy Committee (MPC), headed by the RBI Governor, decides the repo rate by majority vote.

Q: What happens to liquidity when RBI cuts SLR?

Banks free up funds locked in securities, increasing lendable resources and expanding credit in the economy.

Q: Is CRR a quantitative or qualitative tool?

Quantitative — it controls the overall money supply, not the direction or purpose of credit.
