RBI & Monetary Policy — MPC, Inflation Targeting & Tools

RBI's Monetary Policy Mandate

The Reserve Bank of India (RBI), established under the RBI Act, 1934, is India's central bank. Its core mandate in monetary policy is to:

1. Maintain price stability (control inflation)
2. Support economic growth (not at the cost of price stability)
3. Maintain financial stability

The RBI Act was amended by the Finance Act, 2016 (effective June 2016) to provide a statutory basis for the inflation targeting framework and to establish the Monetary Policy Committee (MPC).

Inflation Targeting Framework

India adopted a flexible inflation targeting (FIT) framework in 2016, formally embedded in the RBI Act.

CPI target: 4% (with a tolerance band of ±2%, i.e., 2% to 6%)

Mandate source: The Central Government sets the target every 5 years in consultation with the RBI. The current mandate (re-notified) retains 4% CPI inflation (±2%) as the target.

What is the mandate for? The MPC is mandated to maintain inflation at the target while giving due regard to the objective of growth.

Accountability: If inflation remains above the upper tolerance band (6%) or below the lower band (2%) for three consecutive quarters, the RBI must explain:

• The reasons for failure
• The remedial actions proposed
• The estimated time within which the target will be achieved

CPI basket used: Consumer Price Index (Combined) — covers both urban and rural areas.

Monetary Policy Committee (MPC)

The MPC was constituted under Section 45ZB of the RBI Act, 1934 (inserted by the Finance Act, 2016).

Composition

The MPC has 6 members:

Voting: Each member has one vote. In case of a tie, the Governor has a casting vote.

Quorum: 4 members.

Meetings: At least 4 times a year. In practice, held 6 times a year (bi-monthly).

Independence: External members cannot be re-appointed; they serve a fixed 4-year term. This ensures independence from both the RBI and the government.

MPC Decision-Making Process

1. RBI staff present the economic assessment
2. Each member may present a statement
3. Each member casts an individual vote — voting is transparent (NOT secret ballot); each member's vote and rationale are publicly disclosed in minutes published within 14 days
4. The resolution of the majority is adopted
5. Minutes (including each member's vote and reasoning) are published within 14 days

Monetary Policy Instruments

Quantitative (General) Tools — Affect Overall Liquidity

1. Repo Rate

• Rate at which RBI lends short-term funds to commercial banks (against government securities)
• Primary policy rate — signals the RBI's monetary stance
• Current repo rate (as of April 2026): 5.25% — held unchanged by Governor Sanjay Malhotra (RBI Governor since 11 December 2024, succeeding Shaktikanta Das) and the MPC; rate cut in December 2025, unchanged at February 2026 and April 2026 meetings. April 2026 hold was unanimous; RBI cited West Asia conflict, crude oil above $100/barrel, and a weakening rupee as key upside inflation risks. FY27 GDP projected at 6.9% and FY27 CPI at 4.6% (revised up from 4.2% in February 2026 due to energy price pressures). Next MPC meeting: June 3–5, 2026

2. Standing Deposit Facility (SDF) Rate

• Rate at which banks can park excess liquidity with RBI without providing collateral
• Introduced in April 2022 as the new floor of the liquidity corridor, replacing the reverse repo rate as the primary liquidity absorption tool
• Set at Repo Rate minus 25 bps (currently 5.00%)

3. Marginal Standing Facility (MSF) Rate

• Emergency overnight borrowing window for banks (above the repo rate)
• Set at Repo Rate plus 25 bps (currently 5.50%)
• Banks can borrow even above their SLR limit (up to 1% of net demand and time liabilities)

4. Bank Rate

• Rate at which RBI buys or rediscounts bills of exchange and commercial papers
• Aligned with MSF rate (currently 5.50%)
• Now largely a signalling rate; the repo rate is the operative policy rate

5. Cash Reserve Ratio (CRR)

• Proportion of a bank's net demand and time liabilities (NDTL) that must be maintained as cash with the RBI
• No interest is paid by RBI on CRR balances
• Current CRR: 3.00% (total cut of 150 bps across two phases: 50 bps in Dec 2024 in two tranches, taking CRR from 4.5% to 4.0%; then 100 bps in 2025 in four tranches, taking CRR from 4.0% to 3.0%)
• Does not earn interest — therefore a cost for banks

6. Statutory Liquidity Ratio (SLR)

• Proportion of NDTL that banks must maintain in approved liquid assets (government securities, cash, gold)
• Current SLR: 18.00%
• Banks can use SLR securities for liquidity through repos

Rate Summary (as of April 2026)

Qualitative (Selective) Tools — Targeted Credit Control

Liquidity Adjustment Facility (LAF)

The LAF is the primary mechanism for day-to-day liquidity management. It consists of:

Liquidity corridor: Bounded by SDF rate (floor) and MSF rate (ceiling), with repo rate as the operating target.

Standing Deposit Facility (SDF) — introduced April 1, 2022: The SDF replaced the fixed rate reverse repo as the floor of the rate corridor. Unlike the reverse repo, the SDF does not require the RBI to provide collateral when absorbing excess liquidity from banks. This gives the RBI more flexibility in liquidity management.

Open Market Operations (OMO)

The RBI buys or sells Government Securities (G-Secs) in the open market to regulate liquidity:

OMOs are a powerful tool — a single OMO can inject/absorb thousands of crores. They also impact government bond yields and therefore the cost of government borrowing.

Operation Twist: A variant where the RBI simultaneously buys long-term bonds and sells short-term bonds to flatten the yield curve (used in 2019-20).

Monetary Policy Transmission

Monetary policy transmission refers to the process by which changes in the RBI's policy rates affect the broader economy (growth and inflation).

The Transmission Chain

Policy rate change → Short-term market rates → Bank lending/deposit rates → Investment and consumption → Output and prices

Channels of Transmission

Limitations of Monetary Policy Transmission in India

1. Administered interest rates: Small savings schemes and PPF rates set by the government; banks compete with these for deposits
2. High government borrowing: Fiscal dominance crowds out private investment; RBI must support G-Sec markets
3. Structural inflation: India's inflation is often driven by food supply shocks — not responsive to monetary tools
4. Credit market segmentation: Large informal credit market bypasses formal banking channels
5. Weak bank balance sheets: NPA problems limit banks' ability/willingness to pass on rate cuts
6. External shocks: Global commodity prices (especially crude oil) drive domestic inflation regardless of policy rates

Recent MPC Decisions — Rate Cycle 2022–2026

Rate Hike Cycle (May 2022 – February 2023)

The RBI raised rates aggressively to combat post-COVID inflation surge (driven by the Russia-Ukraine war, supply disruptions, and fiscal stimulus):

Pause (April 2023 – December 2024)

Inflation moderated; repo rate held at 6.50% throughout 2023 and most of 2024. The MPC shifted to a "withdrawal of accommodation" stance, then to "neutral" in October 2024.

Rate Cut Cycle (February 2025 onwards)

With inflation sustainably approaching the 4% target and growth moderating, the MPC began cutting rates:

Monetary Policy Stances

The MPC also signals its future intentions through its stated stance:

Forward Guidance and Communication

Modern central banking relies heavily on communication strategy:

• MPC resolution: Published immediately after each meeting
• Minutes: Published within 14 days with each member's vote and rationale
• Monetary Policy Report: Published twice a year with forecasts for growth and inflation
• Governor's press conference: After every MPC meeting
• Annual Report and currency management reports

This transparency reduces market uncertainty and strengthens transmission.

Recent Developments (2024–2026)

RBI's 2025 Rate-Cutting Cycle — Policy Pivot Analysis

The complete rate trajectory (6.50% → 5.25% in four steps during 2025) is in the Rate Cut Cycle table above. The analytical dimension worth unpacking for Mains is the policy pivot mechanics:

The 10-month pause (October 2024: stance changed from "withdrawal of accommodation" to "neutral") before actual cuts began in February 2025 is not indecision — it is sequential credibility signalling. The MPC needed markets to believe the 4% inflation target was durably met, not just a transient dip. If cuts came too early, investors would read them as premature easing, pushing long-term bond yields up and potentially re-accelerating inflation expectations. The neutral stance change was the "we're considering cuts" signal; the February 2025 cut was the confirmation.

The June 2025 double cut (50 bps) is the analytically interesting outlier. Single MPC cuts are conventional; 50 bps signals urgency. The trigger: Q1 FY26 GDP data (released late May 2025) showed a growth deceleration to 6.0%, below consensus. The MPC's "due regard to growth" mandate — secondary to price stability in law but increasingly operative in practice — justified the larger step. This is the inflation-growth trade-off in action.

Governor transition dynamics: Shaktikanta Das (served 2018-December 2024) had resisted rate cuts through 2024 despite moderation, prioritising inflation credibility. Sanjay Malhotra (from December 2024) moved faster on cuts — reinforcing the institutional observation that RBI Governors have measurable "dovish/hawkish" tendencies that influence transmission beyond the mechanical rate decision.

UPSC angle: The pause-then-cut sequencing (credibility signalling), the June 2025 50-bps rationale (growth deceleration), and the inflation-growth mandate dual objective are strong Mains GS3 analytical frameworks beyond the rate trajectory numbers.

New MPC Composition — Three External Members Appointed (2024)

The Union Government appointed three new external members to the MPC in October 2024: Ram Singh (Director, Delhi School of Economics), Saugata Bhattacharya (former Chief Economist, Axis Bank), and Nagesh Kumar (Director, ISID). They replaced the outgoing members (Ashima Goyal, Jayanth Varma, Shashanka Bhide) whose terms ended. The three RBI-side members are the Governor, Deputy Governor (Monetary Policy), and the Executive Director (Monetary Policy).

The MPC's legal mandate was reaffirmed by the government's five-year review of the FIT framework: the Government of India formally notified (gazette notification dated 25 March 2026) the retention of the 4% CPI target and ±2% tolerance band for the period 1 April 2026 to 31 March 2031 — the second such extension since 2016, under Section 45-ZA of the RBI Act. This provides institutional stability for monetary policy planning and removes uncertainty about whether the target would be changed.

UPSC angle: MPC member appointment process (Centre appoints 3 external members after consultation with RBI), the October 2024 new member names, and the FIT framework five-year review outcome are UPSC-relevant current affairs.

RBI Forex Reserves — All-Time High $728.49 Billion (February 2026)

India's foreign exchange reserves touched an all-time high of $728.49 billion in February 2026, before declining to approximately $688.9 billion (week ending 15 May 2026, Business Standard / RBI data) amid dollar outflows linked to the West Asia conflict and crude oil price pressures. The reserve accumulation reflects strong service exports, remittances, and capital inflows. The reserves continue to cover approximately 10–11 months of merchandise imports — well above the standard international adequacy benchmark of 3 months.

The RBI intervened actively in the forex market in 2024-25 to prevent excessive INR volatility, using its reserves buffer. The INR depreciated from approximately Rs. 83/USD (April 2024) to Rs. 87/USD (January 2026) — a managed depreciation that the RBI allowed while limiting sharp swings. India's forex reserve adequacy has been cited by credit rating agencies as a key strength supporting the investment-grade rating.

UPSC angle: Forex reserves all-time high ($728.49 billion, Feb 2026), current level ~$688.9 billion (May 2026), import cover metric, RBI's dual role (inflation targeting + exchange rate management), and the IMF's Special Data Dissemination Standard (which India follows for reporting forex reserves) are exam-relevant.

Monetary Policy Transmission — Challenges and Progress

Despite four rate cuts totalling 125 bps in 2025, monetary policy transmission remains a challenge. Commercial bank lending rates on new loans fell by approximately 60-70 bps (less than the full 125 bps repo cut), reflecting banks' cost of deposits (which remain sticky) and asset quality concerns. The Economic Survey 2024-25 highlighted the need for deeper bond markets, better liquidity management, and structural reforms to improve transmission.

The RBI's shift from MCLR (Marginal Cost of Funds-based Lending Rate) to EBLR (External Benchmark Lending Rate — linked to repo rate) for retail and MSME loans since October 2019 has improved rate transmission, but corporate loans still use MCLR, creating a dual-track transmission system.

UPSC angle: The monetary policy transmission gap (why rate cuts don't fully pass through to borrowers), MCLR vs EBLR distinction, and the RBI Financial Stability Report's systemic risk assessments are standard Mains GS3 monetary policy topics.

RBI February 2026 MPC — MSME Collateral-Free Loan Limit Doubled to Rs. 20 Lakh

At the February 2026 MPC meeting, Governor Sanjay Malhotra announced that the collateral-free loan limit for Micro and Small Enterprises (MSEs) is doubled from Rs. 10 lakh to Rs. 20 lakh, effective from 1 April 2026. The rationale given was "indexing for inflation" — the earlier Rs. 10 lakh threshold had been set over a decade ago and had eroded in real terms. The change applies to all loans sanctioned or renewed on or after 1 April 2026 under the Priority Sector Lending framework.

This measure directly addresses the MSME credit gap — micro and small enterprises lacking assets to pledge as collateral are the most financially excluded segment. By doubling the threshold, the RBI enables a larger pool of MSME borrowers to access institutional credit without collateral, complementing the Budget 2025-26 measures (CGTMSE limit raised to Rs. 5 crore; Udyam credit card at Rs. 5 lakh). Additionally, the amended RBI directions (notified 9 February 2026, effective 1 April 2026) permit banks to extend up to Rs. 25 lakh to MSEs with a strong track record and sound financials, as per each bank's internal policy. The February 2026 MPC also held the repo rate unchanged at 5.25% (first hold after the December 2025 cut; April 2026 was the second consecutive hold).

UPSC angle: The collateral-free loan limit doubling (Rs. 10 lakh → Rs. 20 lakh, effective 1 April 2026) is a significant Priority Sector Lending reform directly from an MPC meeting — a rare intersection of monetary policy and MSME finance that UPSC may test. The Priority Sector Lending norms (40% of ANBC for domestic banks, 18% for agriculture) remain standard Prelims content.

April 2026 MPC — Pause, FY27 Projections, and the Road Ahead

The April 8, 2026 MPC meeting (first of FY27) held the repo rate at 5.25% in a unanimous decision, retaining the neutral stance for the second consecutive meeting (after the February 2026 hold). The key analytical addition was a significantly revised macro outlook:

The downgrade to GDP (7.4% → 6.9%) and upgrade to inflation (4.2% → 4.6%) reflect the combined impact of the West Asia conflict — crude oil above $100/barrel, supply chain disruptions, and a weakening rupee. The Q3 FY27 CPI projection of 5.2% is within the tolerance band but signals the MPC has limited room to cut rates in FY27 without risking overshooting the upper band.

The next MPC meeting is June 3–5, 2026 (outcome announced June 5, 2026). A Business Standard poll (May 24, 2026) shows consensus for a pause at 5.25%; Standard Chartered is an outlier expecting a rate hike cycle to begin (cumulative 50 bps of hikes in FY27). The June 2026 decision will incorporate two additional months of CPI data and a clearer read on crude trajectories — making it the first genuine FY27 policy inflection point.

UPSC angle (Prelims 2027): April 2026 MPC outcome (unanimous hold, neutral stance), FY27 GDP 6.9% and CPI 4.6% projections, and the June 3–5, 2026 upcoming meeting are live current affairs. The growth-inflation trade-off caused by a geopolitical supply shock (West Asia conflict → crude → domestic inflation) is a textbook Mains GS3 analytical scenario.

CPI Inflation Data — April 2026 Actual (3.48%)

India's Consumer Price Index (CPI) inflation for April 2026 was 3.48% year-on-year (provisional; MoSPI, May 2026) — well below the RBI's 4% target and below market expectations of ~3.8%. This represents the headline CPI (All India Combined). Key breakdown:

The April 2026 figure means India's CPI inflation has remained within the 2-6% tolerance band for a sustained period. For the full year FY 2025-26, the average CPI was approximately 2.1% — one of the lowest in recent years (reflecting the base effect, good monsoon, and moderation in vegetable prices). The MPC's April 2026 meeting (8 April 2026) incorporated Q4 FY26 CPI data; the upward revision of FY27 CPI projections to 4.6% reflects the West Asia conflict's expected impact rather than current trends.

UPSC angle (Prelims 2027): April 2026 headline CPI = 3.48% (rural 3.74%, urban 3.16%, food 4.20%). Full-year FY 2025-26 CPI average ≈ 2.1%. These are below the 4% target — relevant for understanding why the RBI cut rates through 2025. The distinction between headline CPI (3.48%) and urban CPI (3.16%) is sometimes tested.

Exam Strategy

Key Prelims facts:

• MPC = 6 members (3 RBI + 3 Government nominees); Governor has casting vote
• Inflation target = 4% CPI ±2% (2% to 6%); mandated under RBI Act as amended in 2016; renewed 25 March 2026 for 1 April 2026 – 31 March 2031
• SDF introduced April 2022 — new floor of corridor, replaced reverse repo rate
• CRR = 3.00%; SLR = 18.00%; Repo = 5.25% (unchanged since December 2025 cut; April 2026 MPC: unanimous hold, neutral stance)
• FY27 GDP projected at 6.9%; FY27 CPI at 4.6% (April 2026 MPC projections, revised for West Asia conflict impact)
• If inflation misses target for 3 consecutive quarters → RBI must submit written explanation to the Government (NOT to Parliament)

Key Mains points:

• Harmonise monetary and fiscal policy — fiscal consolidation supports monetary policy
• Structural vs demand-driven inflation in India — monetary policy tools are less effective against supply-side food inflation
• MCLR (Marginal Cost of Funds based Lending Rate) system ensures better transmission vs the old base rate system
• External factors: global crude oil, USD strength, capital flows affect domestic monetary conditions

Do not confuse:

• Repo rate (RBI lends to banks) vs SDF (banks park funds with RBI)
• CRR (cash with RBI, no interest) vs SLR (liquid assets including g-secs, earns yield)
• OMO purchase (liquidity injection, expansionary) vs OMO sale (liquidity absorption, contractionary)
• MSF rate = Bank rate = Repo + 25 bps; SDF rate = Repo - 25 bps

Key Terms

Repo vs Reverse Repo

• Definition: The repo rate is the interest rate at which the RBI lends short-term funds to commercial banks against government securities, while the reverse repo rate is the rate at which the RBI borrows from (i.e., absorbs surplus liquidity of) banks; the former injects liquidity, the latter drains it.
• Context: Both are part of the RBI's Liquidity Adjustment Facility (LAF) and are decided by the six-member Monetary Policy Committee (MPC) under the flexible inflation-targeting framework. The repo rate is the RBI's principal policy rate and the benchmark to which most floating-rate retail loans are externally linked. Since the Standing Deposit Facility (SDF) was introduced on 8 April 2022, the fixed-rate reverse repo has been retained in the toolkit but is no longer the operational floor of the LAF corridor.
• UPSC Relevance: This is a foundational GS3 (Indian Economy — monetary policy) concept that underpins questions on inflation control, the LAF corridor, and monetary transmission. Prelims commonly tests the direction of liquidity flow (repo = RBI lends; reverse repo = RBI borrows) and which rate is higher, while Mains links it to inflation-growth trade-offs and the effectiveness of monetary transmission. Aspirants must distinguish it from the SDF, MSF and Bank Rate within the policy corridor — a frequently confused cluster. No direct standalone PYQ is cited here; treat it as a foundation concept supporting the broader monetary-policy question family.

Liquidity Trap

• Definition: A liquidity trap is a situation in which expansionary monetary policy becomes ineffective because nominal interest rates are at or near zero, so people prefer to hold cash rather than bonds, and any increase in the money supply fails to lower interest rates or boost aggregate demand.
• Context: The term was coined by John Maynard Keynes in his 1936 work, The General Theory of Employment, Interest and Money, as part of his liquidity preference theory of interest. Keynes argued that once interest rates fall to a very low level, liquidity preference becomes "virtually absolute" — almost everyone prefers cash to debt instruments yielding negligible returns, leaving the central bank without effective control over interest rates. The concept was revived by economist Paul Krugman to explain Japan's prolonged stagnation and was widely discussed during the 2008 Global Financial Crisis and the COVID-19 downturn, when major central banks pushed policy rates close to the zero lower bound.
• UPSC Relevance: This is a foundational macroeconomics concept that underpins UPSC questions on the limits of monetary policy, the monetary-versus-fiscal policy debate, and the transmission mechanism — recurring themes in GS3 (Indian Economy: monetary policy, RBI, inflation, growth). In Prelims, it can appear as a conceptual/match-the-following item alongside terms like zero lower bound, quantitative easing and liquidity preference. In Mains GS3, examiners typically frame it within a broader question on why rate cuts may fail to revive demand and why fiscal stimulus becomes necessary in a slowdown, so aspirants should be able to explain the mechanism and the escape routes rather than just define it.

Velocity of Money

• Definition: Velocity of money is the average number of times a single unit of currency changes hands to finance transactions of goods and services in an economy over a given period; it measures how fast money circulates rather than how much money exists.
• Context: The concept is central to the Quantity Theory of Money, formalised by economist Irving Fisher in his "equation of exchange" (MV = PT), where M is money supply, V is velocity, P is the price level and T is the volume of transactions. Velocity is not directly observed but is derived residually — typically as nominal GDP divided by a chosen money-supply measure (M1 or broad money M3). In India, the Reserve Bank of India historically used the projected growth of broad money (M3), adjusted for expected changes in velocity, as an intermediate target of monetary policy before the 2016 shift to flexible inflation targeting.
• UPSC Relevance: This is a foundational concept that underpins UPSC questions on monetary policy, money supply, inflation and the Quantity Theory of Money in GS3 (Indian Economy). Prelims commonly tests the equation of exchange (MV = PT) and the distinction between income velocity and transactions velocity, while Mains can frame it around why monetary aggregates became unreliable intermediate targets, pushing the RBI towards inflation targeting. No direct PYQ is cited for this exact term; it remains a building block for the broader money-and-banking topic family.

Marginal Standing Facility

• Definition: The Marginal Standing Facility (MSF) is an overnight liquidity window of the Reserve Bank of India under which scheduled commercial banks can borrow emergency funds against government securities by dipping into their Statutory Liquidity Ratio (SLR) holdings, at a penal rate set 25 basis points above the policy repo rate. It marks the upper bound (ceiling) of the RBI's interest-rate corridor under the Liquidity Adjustment Facility (LAF).
• Context: The MSF was introduced by the RBI in its 2011-12 Monetary Policy (effective 9 May 2011) to give banks an assured last-resort borrowing window and to curb sharp spikes in the overnight call money rate. Banks tap MSF only after exhausting their normal LAF (repo) limits, and the facility is deliberately priced above the repo rate to discourage routine use. Crucially, MSF lets banks borrow against securities they hold to meet the SLR, providing a safety valve during liquidity stress. As of the June 2026 MPC, the MSF rate stands at 5.50% (repo rate 5.25% + 25 bps).
• UPSC Relevance: This is a foundational concept that underpins UPSC questions on monetary policy instruments, the LAF corridor, and RBI's liquidity management. For Prelims, aspirants must distinguish MSF (ceiling, repo + 25 bps, allows dipping into SLR) from the repo rate and the Standing Deposit Facility (SDF, the floor, repo - 25 bps) — a classic source of confusion. For Mains GS3, MSF features in answers on monetary policy transmission, interest-rate corridor design, and how the RBI stabilises short-term rates. No verified PYQ targets this exact term, but it is a recurring building block in the monetary-policy topic family.

Open Market Operations

• Definition: Open Market Operations (OMOs) are the outright purchase or sale of government securities (G-secs and treasury bills) by the Reserve Bank of India in the open market to inject or absorb durable (long-term) liquidity in the banking system as part of monetary policy.
• Context: Open Market Operations are the RBI's purchase or sale of government securities in the open market to manage durable liquidity in the banking system.
• UPSC Relevance: OMO is a foundational concept in the Indian Economy section of GS3 (monetary policy, money supply, RBI instruments) and is frequently tested in Prelims through distinctions between quantitative instruments (OMO, CRR, SLR, repo rate, MSS, bank rate). A common Prelims trap is confusing OMO (outright, durable liquidity) with LAF repo/reverse repo (temporary), and with the Market Stabilisation Scheme (sterilisation, proceeds parked separately and not used for government spending). In Mains GS3, OMOs feature in answers on monetary transmission, liquidity management, and the inflation-growth trade-off. Foundational concept — underpins questions on the monetary policy framework, money supply and central banking.

Cash Reserve Ratio (CRR)

• Definition: The Cash Reserve Ratio (CRR) is the minimum percentage of a bank's Net Demand and Time Liabilities (NDTL) that every scheduled bank must maintain as a cash reserve with the Reserve Bank of India, on which the RBI pays no interest. It is mandated under Section 42(1) of the Reserve Bank of India Act, 1934.
• Context: CRR is one of the RBI's principal quantitative tools of monetary policy, used alongside the Statutory Liquidity Ratio (SLR) and policy rates to manage liquidity in the banking system. By raising or lowering the proportion of deposits banks must park with the central bank, the RBI directly controls how much money banks can lend, thereby influencing money supply, credit growth and inflation. Banks earn no interest on these balances, so CRR also acts as a cost on the banking system. The required reserve is maintained on a fortnightly average basis, with banks holding a minimum of 90% of the requirement on each day and 100% on average over the reporting fortnight.
• UPSC Relevance: CRR is a foundational concept for GS3 (Indian Economy — monetary policy, money supply, banking) and a recurring Prelims favourite. Prelims questions typically test whether students can distinguish CRR from SLR, identify the legal basis (Section 42 of the RBI Act, 1934, versus SLR under the Banking Regulation Act, 1949), and reason about how a CRR change affects liquidity, lending capacity and the money multiplier — for instance, that a CRR cut releases funds and is expansionary. This is a foundational concept that underpins questions on monetary policy transmission, instruments of credit control, and the RBI's inflation-targeting framework. Mains relevance lies in analysing the trade-off between liquidity, growth and price stability rather than rote recall.

Repo Rate

• Definition: The repo (repurchase) rate is the policy interest rate at which the Reserve Bank of India (RBI) lends short-term funds to commercial banks against government securities under the Liquidity Adjustment Facility (LAF), with the banks agreeing to repurchase those securities at a future date. It is the RBI's principal tool for signalling its monetary policy stance and steering the cost of credit in the economy.
• Context: The repo rate sits at the centre of the RBI's LAF corridor, which is bounded by the Standing Deposit Facility (SDF) rate as the floor and the Marginal Standing Facility (MSF) rate as the ceiling. It is fixed by the six-member Monetary Policy Committee (MPC), chaired by the RBI Governor (Sanjay Malhotra, as of June 2026), which meets bi-monthly to anchor inflation around the statutory target of 4% (within a +/- 2% band). When the RBI cuts the repo rate, borrowing becomes cheaper, encouraging credit and growth; when it raises the rate, it tightens liquidity to curb inflation.
• UPSC Relevance: Repo rate is a foundational concept that underpins recurring UPSC questions on monetary policy, inflation targeting, and the LAF framework. In Prelims it is tested factually — distinguishing repo from reverse repo/SDF/MSF, identifying the policy corridor, and knowing who sets the rate (the MPC, not the RBI Governor alone). In Mains GS3 it appears in the context of monetary-fiscal coordination, inflation control versus growth trade-offs, and transmission of policy rates to bank lending rates. Aspirants should not confuse the repo rate (RBI lends to banks) with the reverse repo/SDF rate (banks park funds with RBI) or the bank rate (longer-term, penal lending).
