Direct Answer: What Repo Rate, CRR and SLR Do
RBI Repo Rate, CRR and SLR Explained for Bank Exams
Quick Answer: The repo rate is the rate at which the RBI lends short-term money to banks against government securities — a repo hike makes credit costlier and shrinks money supply. The CRR is the share of deposits banks must park as cash with the RBI (earning no interest), while the SLR is the share held as cash, gold or approved securities — raising either locks up funds and reduces lendable money.

RBI’s Policy Toolkit: Qualitative vs Quantitative Tools
RBI’s monetary policy instruments divide into two families. Quantitative (general) tools affect the total volume of credit; qualitative (selective) tools direct credit to particular sectors or borrowers.
| Quantitative Tools | Qualitative Tools |
|---|---|
| Repo rate, Reverse repo / SDF rate, MSF (under the LAF) | Margin requirements |
| CRR and SLR | Moral suasion |
| Open Market Operations (OMOs), Market Stabilisation Scheme | Selective credit control, credit rationing, direct action |
| Bank Rate, policy corridor width | Publicity and guidelines |
The repo rate, SDF rate and MSF together form the Liquidity Adjustment Facility (LAF), the operational heart of the Monetary Policy Framework run by the six-member MPC (Monetary Policy Committee). For official definitions, see the RBI’s Monetary Policy Report and the RBI website.
Repo Rate Explained with the Transmission Chain
The exam-ready transmission chain you must memorise:
Repo hike → banks’ borrowing from RBI becomes costlier → banks raise lending rates (MCLR/EBLR linked) → loans become expensive → credit demand falls → money supply contracts.
- Repo cut does the opposite: cheaper credit, higher money supply, boost to demand.
- The repo rate is the single policy rate since 2019; the reverse repo rate is no longer separately announced.
- The MPC meets roughly every two months (six bi-monthly meetings a year) and announces its stance — recently a neutral/ accommodative-to-neutral stance with a focus on withdrawal of accommodation shifting toward supporting growth. Always verify the latest repo rate and stance on rbi.org.in before your exam, as rates change with each policy review.
CRR Explained: Cash Reserve Ratio and Lendable Funds
CRR is the percentage of a bank’s Net Demand and Time Liabilities (NDTL) that must be maintained as cash balances with the RBI. Key exam points:
- CRR is held with the RBI and earns no interest — a favourite SSC CGL trap.
- It is maintained fortnightly, on average.
- Raising CRR sucks liquidity out; cutting it releases funds for lending.
Mini numerical: Deposits = ₹1,000 crore, CRR = 4% → ₹40 crore locked with RBI → ₹960 crore lendable. If CRR rises to 5%, ₹50 crore is locked → lendable funds fall to ₹950 crore.
SLR Explained: Statutory Liquidity Ratio and Government Securities
SLR is the percentage of NDTL that banks must maintain with themselves — as cash, gold, or approved securities (mainly G-Secs).
- SLR is set under Section 24 of the Banking Regulation Act, 1949.
- Unlike CRR, SLR assets earn returns — G-Secs pay interest; this is the standard CRR-vs-SLR differentiator.
- SLR creates steady bank demand for government bonds; a higher SLR means more captive demand for G-Secs but less lendable funds.
- Banks must also maintain SLR to access RBI’s LAF window.
Money Multiplier: How a CRR/SLR Change Ripples Through Money Supply
Money multiplier = 1 ÷ reserve ratio. With a reserve ratio of 10%, the multiplier is 10 — every ₹100 of fresh deposits can support up to ₹1,000 of total credit creation.
Worked example: CRR = 10%, initial deposit = ₹1,000.
| Round | Deposit Received | Reserve (10%) | Credit Created |
|---|---|---|---|
| 1 | ₹1,000 | ₹100 | ₹900 |
| 2 | ₹900 | ₹90 | ₹810 |
| 3 | ₹810 | ₹81 | ₹729 |
| … | … | … | … |
| Total | ₹10,000 | ₹1,000 | ₹9,000 |
So the money supply expands tenfold; a CRR hike to 20% would halve the multiplier to 5.
Reverse Repo, MSF and the Corridor — Quick Exam Notes
- SDF (Standing Deposit Facility): the rate at which banks park surplus funds with the RBI without collateral; it replaced the fixed reverse repo as the corridor floor in April 2022.
- MSF (Marginal Standing Facility): banks borrow overnight from RBI against SLR securities (dipping up to 2% below SLR); it is the corridor ceiling.
- The policy corridor is the band between the SDF rate and MSF rate, bracketing the repo rate and keeping overnight call money rates within it.
- Bank Rate is aligned to the MSF rate and applies to long-term RBI lending and penalty pricing.
PYQ Pattern 1: Definition-Matching Questions
Example: “Match the following: (A) Repo rate, (B) CRR, (C) MSF — (1) % of NDTL as cash with RBI, (2) RBI’s lending rate against securities, (3) overnight borrowing against SLR securities.” Answer: A-2, B-1, C-3.
Solving tip: anchor on two anchors first — anything with “cash with RBI, no interest” is CRR; anything with “bank lends to RBI / parks funds” is reverse repo or SDF. Solve anchors first, eliminate the rest.
PYQ Pattern 2: Rise/Fall Effect on Money Supply
Example (SSC CGL / IBPS style): “If the repo rate increases, money supply will ___.” Options: increase / decrease / remain constant / first increase then decrease. Answer: decrease.
Fixed logic to memorise: Repo ↑, CRR ↑, SLR ↑, Bank Rate ↑, OMO sale of securities → money supply ↓ (tight policy). Repo ↓, CRR ↓, SLR ↓, OMO purchase → money supply ↑ (easy policy). Never overthink; this inverse rule holds in every PYQ.
PYQ Pattern 3: Numerical Problems on CRR, SLR and Multiplier
Sample: A bank receives a deposit of ₹2,00,000 and the CRR is 5%. What is the maximum total credit the banking system can create?
- Multiplier = 1/0.05 = 20
- Total credit creation = (2,00,000 × 20) − 2,00,000 = ₹38,00,000 (total money supply ₹40,00,000)
- Shortcut: max credit = deposit × (1 − r)/r; check: 2,00,000 × 0.95/0.05 = ₹38,00,000 ✓
If SLR is also given, some questions add CRR + SLR to get the effective reserve ratio — read the wording carefully.
PYQ Pattern 4: Which Is Not a Quantitative Tool?
Example: “Which of the following is NOT a quantitative instrument of monetary policy? (a) Repo rate (b) Margin requirements (c) CRR (d) Open market operations.” Answer: (b) Margin requirements — a qualitative/selective tool.
Common distractors: moral suasion, selective credit control, margin requirements, direct action, credit rationing — all qualitative. Repo, reverse repo, CRR, SLR, bank rate, OMOs, MSS — all quantitative.
PYQ Pattern 5: Statement-Based UPSC/CLAT Questions
Example (UPSC/CLAT style): Consider the statements: (1) RBI pays interest on CRR balances. (2) SLR can include gold and approved securities. (3) The MPC has six members including the RBI Governor. Which are correct?
Answer: 2 and 3 only. Statement 1 is false — CRR earns no interest.
Elimination strategy: kill any statement containing “RBI pays interest on CRR” or “CRR earns market returns” first; then check SLR asset lists (cash, gold, approved securities — never equities) and MPC facts (6 members, Governor is chair, casting vote, External MEMbers appointed for 4 years, quorum 4). One certainty usually eliminates two options.
Revision Table

| SLR | % of NDTL in cash, gold, approved securities | Bank itself | Yes (securities/gold) | Lendable funds ↓ |
| SDF | Banks park funds with RBI (no collateral) | RBI | SDF rate | Corridor floor |
| MSF | Overnight borrowing against SLR securities | — | MSF rate | Corridor ceiling |
Frequently Asked Questions
Q: What is the repo rate in simple words?
It is the interest rate at which the RBI lends short-term funds to banks against government securities. When RBI raises the repo rate, borrowing becomes costlier for banks, who pass it on as costlier loans, reducing money supply.
Q: What is the difference between CRR and SLR?
CRR is cash maintained with the RBI and earns no interest. SLR is maintained by the bank itself as cash, gold or approved securities, and those securities do earn returns. Both are percentages of NDTL.
Q: How does the repo rate affect the common man?
Through the transmission chain: a repo hike raises banks’ lending rates, so home, car and personal loan EMIs rise, while deposit rates also edge up. A repo cut lowers EMIs and makes loans cheaper.
Q: What are the current CRR and SLR requirements?
SLR is currently 18% of NDTL. CRR has historically stood at 4%, though the RBI has adjusted it in recent policy reviews — including phased changes announced in 2025. Because these figures change, always confirm the latest notification on rbi.org.in just before your exam.
Q:Which exams ask the most questions on RBI policy tools?
Banking exams (IBPS PO/Clerk, SBI PO/Clerk) and RBI Grade B ask these every year, especially transmission-chain and numerical questions. SSC CGL favours definition-matching and “not a quantitative tool” questions, while UPSC Prelims Economy and CLAT GK prefer statement-based formats.
