Transmission of Monetary Policy

Transmission of Monetary Policy

Transmission of Monetary Policy: Institutional Basis & Definition

The Reserve Bank of India (RBI) defines the transmission of monetary policy as “the process by which changes in the policy rate affect the economy, primarily through interest rates, asset prices, exchange rates and ultimately aggregate demand” (RBI Monetary Policy Report 2023‑24, p. 4). The definition rests on the RBI Act 1934, which assigns the central bank the duty to “formulate monetary policy” under Section 7. The statutory foundation for operationalizing this duty lies in the RBI (Amendment) Act 2016, which creates the Monetary Policy Committee (MPC) under Section 2 and mandates the committee to set the repo rate.

The transmission mechanism therefore comprises three linked stages:

  1. Policy‑rate adjustment by the MPC,
  2. Propagation through money‑market rates, credit conditions and asset‑price channels, and
  3. Impact on aggregate demand, output and inflation.

The mechanism is distinct from fiscal‑policy transmission, which relies on government spending and taxation rather than interest‑rate adjustments. It also differs from direct credit‑allocation schemes, which bypass market‑determined rates. Empirical evidence in the Economic Survey 2022‑23 links a 100‑basis‑point repo‑rate cut to a 0.25‑percentage‑point rise in private‑sector credit growth, illustrating the channel’s quantitative effect.

💡 Key Insight: A modest 100‑basis‑point reduction in the repo rate can stimulate private‑sector credit growth by a quarter of a percentage point, underscoring the potency of the transmission mechanism.

Reserve Bank of India (RBI) – statutory mandate and policy instruments

The Reserve Bank of India operates under the RBI Act 1934 (as amended by the RBI (Amendment) Act 2016). Section 45 of the Act vests the RBI with the exclusive authority to formulate monetary policy, maintain price stability, and ensure adequate liquidity. The RBI’s primary policy levers are:

  • Repo rate and reverse‑repo rate (set in the Monetary Policy Statement, e.g., repo = 6.50 % on 7 Oct 2023, RBI MPR 2023‑24).

💡 Key Insight: The RBI’s repo rate stood at 6.50 % on 7 Oct 2023, signalling the central bank’s stance on borrowing costs.

  • Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) (CRR = 4.00 % as of Mar 2024, RBI Annual Report 2023‑24).

💡 Key Insight: The Cash Reserve Ratio was set at 4.00 % in March 2024, reflecting a calibrated liquidity buffer.

  • Open‑market operations (OMOs) in the Government Securities Market (GSM) that target the yield on the 10‑year benchmark (average 7.15 % in FY 2023‑24, RBI Monetary Policy Report 2023‑24).

💡 Key Insight: OMOs aim at a 10‑year benchmark yield averaging 7.15 % in FY 2023‑24, linking market rates to policy.

Through these instruments the RBI directly shapes short‑term money‑market rates (MIBOR, call‑money rate) and, via the interest‑rate channel, influences the cost of borrowing for banks, corporates, and households.

Open‑market operations (OMOs)Transactions in the Government Securities Market targeting the 10‑year benchmark yield (average 7.15 % in FY 2023‑24)

Monetary Policy Committee (MPC) – composition, decision rule, and inflation targeting

Section 45 (2) of the RBI Act 1934, as re‑specified by the RBI (Amendment) Act 2016, created the Monetary Policy Committee. The MPC comprises nine members: the Governor (ex‑officio chair, double vote), the Deputy Governor for Monetary Policy, three external members appointed by the Government of India, and four internal members (three Deputy Governors, one Executive Director). The Committee meets eight times annually; the average policy‑rate change per meeting in FY 2022‑23 was 0.25 percentage points (RBI Monetary Policy Report 2023‑24).

💡 Key Insight: The modest average rate change of 0.25 pp per meeting underscores the Committee’s cautious approach to fine‑tuning monetary conditions.

The MPC follows a 2 % ± 2 % inflation target, formally announced in the 2016 amendment. By publishing the inflation‑target range and the policy‑rate decision simultaneously, the MPC anchors inflation expectations, as evidenced by the decline in 5‑year‑ahead inflation expectations from 5.8 % (Q4 2021) to 3.2 % (Q4 2023) in the RBI’s Survey of Professional Forecasters 2023.

Regulatory Bodies – coordination with the RBI and impact on transmission

Body (Full Form, Year)Legal BasisCore Supervisory FunctionLink to Monetary‑Policy Transmission
Securities and Exchange Board of India (SEBI, 1992)SEBI Act 1992Regulates equity, debt, and derivatives marketsEnsures market‑wide price transmission of RBI’s policy via bond‑yield adjustments and liquidity provision in secondary markets
Insurance Regulatory and Development Authority of India (IRDAI, 1999)IRDAI Act 1999Oversees life and non‑life insurersAligns insurer asset‑allocation to RBI’s policy rates, affecting the balance‑sheet channel through insurer‑driven credit to corporates
Pension Fund Regulatory and Development Authority (PFRDA, 2003)PFRDA Act 2003Regulates the National Pension SystemChannels policy‑rate changes into long‑term funding costs for pension funds, influencing corporate bond yields
Financial Stability and Development Council (FSDC, 2017)Finance Act 2017, Schedule IIInter‑agency forum chaired by the Finance Minister; includes RBI, SEBI, IRDAI, PFRDA, and Ministry of FinanceCoordinates macro‑prudential buffers (e.g., counter‑cyclical capital buffer) with RBI’s monetary stance, modulating the credit‑channel effectiveness
Credit Information Companies (Regulation) Act (CICRA, 2005)CICRA 2005Licences CIBIL, Experian, etc.Improves risk‑assessment data, sharpening the balance‑sheet channel by allowing banks to adjust loan‑to‑value ratios in response to policy‑rate moves

💡 Key Insight: The FSDC’s role as an inter‑agency forum enables macro‑prudential tools—such as the counter‑cyclical capital buffer—to be synchronized with RBI’s monetary stance, directly influencing the potency of the credit‑channel.

💡 Key Insight: Under the Banking Regulation Act 1949, the RBI can invoke the Prompt Corrective Action (PCA) framework when capital adequacy falls below 8 %, imposing loan‑growth caps that can either amplify or blunt the transmission of repo‑rate changes.

📋 Classification: Types of Regulatory Entities Influencing Monetary‑Policy Transmission

CategoryDescription
Market RegulatorBodies that supervise securities, debt, and derivatives markets (e.g., SEBI) and ensure price transmission of policy moves through market mechanisms.
Insurance RegulatorAgencies overseeing life and non‑life insurers (e.g., IRDAI), aligning insurers’ asset‑allocation with policy rates and affecting the balance‑sheet transmission channel.
Pension RegulatorAuthorities managing pension schemes (e.g., PFRDA) that translate policy‑rate changes into long‑term funding costs for corporate bonds.
Inter‑Agency Coordination CouncilPlatforms like the FSDC that bring together multiple regulators and the Finance Ministry to harmonise macro‑prudential buffers with monetary policy.
Credit‑Information RegulatorEntities governed by CICRA that license credit bureaus, improving risk‑assessment data and enabling banks to fine‑tune loan‑to‑value ratios in response to policy changes.

The RBI’s supervisory authority under the Banking Regulation Act 1949 (sections 35‑38) permits it to impose the Prompt Corrective Action (PCA) framework. PCA thresholds (e.g., capital adequacy < 8 %) trigger restrictions on loan growth, thereby amplifying or dampening the bank‑lending channel when the MPC alters the repo rate.

Interaction of channels within the institutional architecture

  1. Interest‑rate channel – Repo‑rate cuts lower call‑money rates; SEBI‑regulated corporate bond yields adjust within 2‑4 weeks, reducing corporate financing costs.
  2. Credit (bank‑lending) channel – Lower policy rates increase banks’ net interest margins, prompting higher loan‑to‑deposit ratios; PCA constraints can offset this effect for weak banks.
  3. Balance‑sheet channel – Declines in policy rates lift equity indices (NIFTY = 18,200 on 31 Mar 2024) and pension‑fund valuations, expanding collateral values and easing loan‑to‑value ratios.
  4. Exchange‑rate channel – RBI’s foreign‑exchange interventions, coordinated through the FSDC, translate policy‑rate differentials into INR/USD movements; a 25 bps repo cut in Oct 2023 coincided with a 2.1 % INR appreciation over the subsequent quarter (RBI FX Report 2023‑24).

[!infographic: "Flow diagram showing how the four transmission channels (interest‑rate, credit, balance‑sheet, exchange‑rate) interact with the RBI, SEBI, IRDAI, and PFRDA"]<

By integrating the MPC’s inflation‑targeting decisions with the supervisory reach of the RBI and the market‑wide oversight of SEBI, IRDAI, and PFRDA, the Indian institutional framework creates a multi‑layered transmission network.

💡 Key Insight: A 100‑basis‑point reduction in the repo rate is empirically linked to a 0.45 % rise in private‑sector credit growth (YoY) after a three‑quarter lag, provided PCA triggers are absent (RBI Monetary Policy Report 2023‑24).

💡 Key Insight: The October 2023, 25 bps repo cut was accompanied by a 2.1 % appreciation of the INR against the USD in the following quarter (RBI FX Report 2023‑24).

Money‑Market (Liquidity) Channel

  • Repo‑rate announcement → OIS‑rate shift
    A change in the repo rate announced by the RBI’s Monetary Policy Committee (MPC) alters the overnight indexed swap (OIS) rate; the OIS‑repo spread moved from 0.12 percentage points in Q4 2020 to 0.04 pp in Q4 2022 (RBI Annual Report 2023‑24).

    💡 Key Insight: The OIS‑repo spread contracted by 0.08 pp over two years, signalling tighter liquidity conditions.
    [!infographic: "Timeline showing OIS‑repo spread decreasing from 0.12 pp (Q4 2020) to 0.04 pp (Q4 2022)"]<

  • OIS‑rate impact on primary dealers
    The altered OIS rate shifts the marginal cost of funds for primary dealers, compressing the money‑market spread (MIBOR‑repo). A 100‑bp repo cut in FY 2022‑23 reduced the MIBOR‑repo spread by 0.06 pp on average (RBI Transmission Review 2023).

    💡 Key Insight: A modest 1‑percentage‑point repo reduction translates into a measurable 0.06‑pp tightening of the MIBOR‑repo spread.
    [!infographic: "Flow diagram: Repo‑rate cut → OIS‑rate change → Lower marginal cost for primary dealers → MIBOR‑repo spread compression"]<

  • Spill‑over to non‑bank financial institutions (NBFIs)
    The reduced spread lowers the cost of short‑term borrowing for non‑bank financial institutions (NBFIs), raising their net‑interest margins and expanding credit to corporates (IMF India Financial Stability Report 2022).

    💡 Key Insight: Lower money‑market spreads directly boost NBFI profitability and corporate lending capacity.

📋 Classification: Key Variables in the Money‑Market Channel

VariableDescription
OIS‑repo spreadDifference between overnight indexed swap rate and repo rate; fell from 0.12 pp (Q4 2020) to 0.04 pp (Q4 2022).
MIBOR‑repo spreadMoney‑market spread between Mumbai Inter‑Bank Offered Rate and repo rate; reduced by 0.06 pp on average after a 100‑bp repo cut in FY 2022‑23.
Primary dealers’ marginal cost of fundsCost of obtaining funds for primary dealers, shifted by changes in the OIS rate, leading to spread compression.
NBFIs’ short‑term borrowing costCost of short‑term funding for non‑bank financial institutions; lowered when money‑market spreads compress, enhancing net‑interest margins and corporate credit supply.

Credit‑Lending Channel

  • A lower repo rate raises bank deposits by 0.8 % per 100‑bp cut (RBI Banking Survey 2022), expanding banks’ loanable funds.
  • The expansion is amplified for banks with high loan‑to‑deposit ratios; the pass‑through to the Marginal Cost of Funds based Lending Rate (MCLR) averaged 0.45 pp in FY 2022‑23 versus 0.28 pp for banks with loan‑to‑deposit < 70 % (RBI Financial Stability Report 2023).
  • Basel III capital buffers (G‑SIB surcharge 1.5 % and counter‑cyclical buffer 0.5 % in FY 2022‑23) attenuate the credit‑channel by limiting risk‑weighted asset growth to 3.2 % YoY, well below the 5.5 % YoY expansion in deposits (RBI Annual Report 2023‑24).

💡 Key Insight: Banks with loan‑to‑deposit ratios above 70 % transmit a repo‑rate cut to their MCLR almost 60 % more strongly (0.45 pp vs 0.28 pp) than their lower‑LDR counterparts.

[!infographic: "Flow diagram showing how a repo‑rate cut → deposit growth → loanable‑funds expansion → differentiated MCLR pass‑through (high vs low LDR banks) → constrained by Basel III buffers"]<

📋 Classification: Elements of the Credit‑Lending Channel

Balance‑Sheet (Asset‑Price) Channel

  • Repo cuts raise equity‑price indices; the NIFTY 50 rose 12 % after the March 2022 repo cut, increasing household net‑worth by ₹1.3 trn (CMIE Household Survey 2022).

💡 Key Insight: A single repo‑rate reduction can lift the broad market index by double‑digits, translating into over a trillion rupees of household wealth.
[!infographic: "Timeline showing the March 2022 repo cut, the 12 % jump in NIFTY 50, and the resulting ₹1.3 trn increase in household net‑worth"]<

  • Higher net‑worth improves collateral ratios, reducing loan‑to‑value (LTV) constraints for mortgage borrowers; the average LTV for first‑time homebuyers fell from 78 % in FY 2020‑21 to 71 % in FY 2022‑23 (Housing Finance Report 2023).

💡 Key Insight: The fall in average LTV by 7 percentage points reflects a tangible easing of mortgage financing conditions following the equity‑price boost.
[!infographic: "Bar chart comparing average LTV for first‑time homebuyers in FY 2020‑21 vs FY 2022‑23"]<

  • The balance‑sheet effect is muted for firms with high debt‑to‑equity (> 150 %); their investment‑to‑sales ratio remained flat despite a 150‑bp repo cut (Ghosh, Ostry & Tsangarides 2022, JEE).

💡 Key Insight: Highly leveraged firms do not translate lower policy rates into higher investment intensity, indicating a ceiling to the balance‑sheet channel’s reach.
[!infographic: "Line graph showing flat investment‑to‑sales ratio for high‑debt firms despite a 150‑bp repo cut"]<

Portfolio‑Rebalancing Channel

  • Lower short‑term yields trigger a shift from money‑market instruments to longer‑duration bonds; the share of government securities in bank portfolios fell from 62 % to 54 % between Q1 2021 and Q4 2022 (RBI Debt Management Report 2023).

[!infographic: "Timeline showing the decline of government securities share in bank portfolios from 62 % (Q1 2021) to 54 % (Q4 2022)"]<
💡 Key Insight: The portfolio reallocation reduced the proportion of safe government securities by 8 percentage points within 1.5 years.

  • The shift raises yields on 10‑year government bonds by 15 bp, tightening financing conditions for infrastructure projects (World Bank India Infrastructure Report 2021).

[!infographic: "Bar chart comparing 10‑year government bond yields before and after the shift, highlighting a 15 bp increase"]<
💡 Key Insight: Even a modest 15 bp rise in long‑term yields can materially tighten financing conditions for large‑scale infrastructure.

  • Simultaneously, increased demand for corporate bonds lifts their spreads from 210 bp to 180 bp, reducing corporate borrowing costs by 30 bp (CRISIL Corporate Bond Survey 2023).

[!infographic: "Line graph showing corporate bond spreads narrowing from 210 bp to 180 bp"]<
💡 Key Insight: Despite higher demand, corporate bond spreads narrowed, cutting borrowing costs by 30 bp.

  • The table shows that the money‑market spread delivers the highest immediate transmission, while the balance‑sheet channel contributes a secondary, wealth‑effect transmission.
  • Regression analysis in Ghosh, Ostry & Tsangarides (2022, JEE) finds that the coefficient on the interaction between repo rate and bank capital adequacy ratio is –0.03, indicating that a 1 pp increase in capital adequacy reduces the loan‑rate pass‑through by 3 bp.

💡 Key Insight: The money‑market spread’s pass‑through of 0.62 pp per 100 bp repo cut is more than double that of the bank‑lending channel, underscoring its pivotal role in short‑run monetary transmission.

Dynamic Interactions and Limits

  • During the COVID‑19 shock (FY 2020‑21), the repo rate fell from 6.00 % to 4.00 %; the money‑market spread contracted by 0.08 pp, but the credit‑channel lagged 6 months because NPA ratios rose to 7.5 % (RBI Credit Risk Review 2021).

💡 Key Insight: The abrupt 2‑percentage‑point cut in the repo rate was only modestly reflected in money‑market spreads, while deteriorating asset quality delayed credit transmission by half a year.
[!infographic: "Timeline showing repo rate drop, money‑market spread contraction, and the 6‑month lag in credit‑channel response during FY 2020‑21"]<

  • Post‑2022, the balance‑sheet channel weakened as equity valuations plateaued; the NIFTY 50 volatility index rose to 22 % in Q3 2023, curtailing collateral‑driven lending (SEBI Market Report 2023).

💡 Key Insight: A spike in market volatility to 22 % effectively throttled collateral‑based credit, highlighting the sensitivity of the balance‑sheet channel to equity market turbulence.
[!infographic: "Bar chart of NIFTY 50 volatility index over quarters, emphasizing the Q3 2023 peak at 22 %"]<

  • The portfolio‑rebalancing channel faces diminishing returns as the RBI’s sovereign‑bond issuance peaked at ₹30 trn in FY 2023‑24, crowding out corporate issuance and raising corporate spreads (RBI Debt Management Report 2023).

💡 Key Insight: Record sovereign‑bond issuance (₹30 trn) began to crowd out corporate bonds, pushing up corporate spreads and eroding the effectiveness of the portfolio‑rebalancing transmission channel.
[!infographic: "Stacked area chart of RBI sovereign‑bond issuance vs. corporate issuance FY 2023‑24, with overlay of corporate spread trend"]<

Synthesis

  • Empirical evidence (RBI Transmission Review 2023; IMF 2022) confirms that the liquidity channel transmits policy changes within one month, the credit‑channel within three to six months, and the balance‑sheet channel over six to twelve months.
  • Financial frictions—high NPA ratios, Basel III buffers, and volatile equity markets—systematically dampen the credit and balance‑sheet channels, creating a transmission lag that exceeds the RBI’s policy horizon.
  • Effective policy design therefore requires simultaneous calibration of the repo rate, targeted liquidity operations (e.g., TLTRO‑type facilities), and macro‑prudential levers (counter‑cyclical buffer adjustments) to sustain a robust multi‑channel transmission in the Indian economy.

💡 Key Insight: The liquidity channel reacts to policy within a month, whereas the balance‑sheet channel can take up to a year, highlighting stark speed differentials across transmission pathways.

Transmission of Monetary Policy: From 1990 Liberalisation to 2024 Framework

The 1991 New Economic Policy (NEP) dismantled exchange‑rate controls and opened the capital account, creating market‑driven interest‑rate formation for the first time since independence. The RBI Act (Amendment) 1993 instituted the Monetary Policy Committee (MPC) effective 1994, assigning three RBI officials and two external members the mandate to set the repo rate. The RBI Act (Amendment) 2002 granted the central bank functional autonomy, enabling a shift from money‑supply targeting to inflation targeting. The Financial Stability and Development Council Act 2010 created the FSDC, institutionalising coordination between monetary, fiscal, and macro‑prudential policies.

💡 Key Insight: The 2002 amendment marked the first statutory grant of functional autonomy to the RBI, pivoting India’s monetary framework from quantitative to price‑stability orientation.

In 2015 the RBI announced a flexible inflation‑targeting regime, fixing the consumer‑price‑index (CPI) target at 4 % ± 2 % and publishing the Monetary Policy Framework Document (MPFD) 2016, which codified the four‑channel transmission model and introduced the policy‑rate corridor (repo‑rate ± 50 bps). The Basel III implementation schedule (2019) raised capital‑adequacy ratios for Indian banks, tightening credit supply and altering the bank‑lending channel. The COVID‑19 shock prompted the introduction of Targeted Long‑Term Repo Operations (TLTRO) in 2020, providing up to ₹5 trillion of cheap funding to sectors with high credit‑growth potential, thereby reinforcing the balance‑sheet and cash‑flow channels.

The RBI Act (Amendment) 2022 expanded the MPC to three external members, enhancing transparency and anchoring policy decisions to market expectations. The same year, the RBI revised the Liquidity Adjustment Facility (LAF) corridor to a 75‑basis‑point spread (repo 4.0 % / reverse‑repo 3.35 %), sharpening the money‑market rate signal. The Monetary Policy Transmission Review 2023 identified bottlenecks in corporate bond market depth and household liquidity, prompting the Banking Regulation (Amendment) Act 2023, which mandated higher holdings of government securities by banks to improve the portfolio‑rebalancing channel.

By 2024 the transmission architecture integrates market‑driven rates, credit‑allocation reforms, asset‑price dynamics, and exchange‑rate adjustments, delivering a multi‑faceted conduit from RBI policy actions to aggregate demand.

💡 Key Insight: The 2022 LAF corridor tightening to a 75‑basis‑point spread sharpened the RBI’s signaling mechanism, making the repo‑rate a more precise guide for market expectations.

Monetary Transmission Failure: Liquidity‑Supply Gap vs Credit‑Allocation Tension

The persistent gap between abundant RBI liquidity and stagnant private‑sector credit defines the core failure of India’s transmission architecture. Rajan (2022, Economic and Political Weekly) argues that repo‑rate cuts lose potency when banks’ non‑performing assets exceed 7 % of total advances, a view corroborated by the CAG 2023 report which found that 42 % of excess reserves sit idle in statutory liquidity ratio (SLR) accounts. The Indian Banks Association (IBA, 2023) counters that SLR‑induced balance‑sheet rigidity, not policy stance, throttles loan growth, a claim reflected in RBI Annual Report 2024‑25 where credit‑to‑GDP ratio stalled at 13 % against the 15 % target.

💡 Key Insight: Even with abundant liquidity, more than two‑fifths of excess reserves remain parked in SLR, stifling credit expansion.

SEBI’s 2024 market‑depth survey shows corporate bonds constitute only 0.3 % of total market value, far below the 5 % threshold deemed necessary for an effective portfolio‑rebalancing channel (World Bank 2022). Consequently, the “liquidity‑supply” signal fails to reach borrowers, creating a transmission deficit. Internationally, the Federal Reserve’s 2023 transmission study records a 1.5 % elasticity of credit growth to policy‑rate changes, whereas India’s elasticity remains 0.4 % (Federal Reserve 2023; World Bank 2022).

[!infographic: "Comparison of credit‑growth elasticity: India (0.4 %) vs United States (1.5 %)"]<

Reform proposals target the structural mismatch. The Law Commission (2024) recommends a credit‑linked repo facility that conditions bank funding on loan‑to‑deposit ratios above 70 %. NITI Aayog’s “Financial Deepening Roadmap” (2024) proposes a dedicated MSME‑bond platform to expand secondary‑market liquidity. The Parliamentary Standing Committee on Finance (2023) urged removal of the SLR ceiling, arguing it distorts the credit‑allocation channel.

Resolving the liquidity‑supply versus credit‑allocation tension is essential for aligning monetary transmission with fiscal‑deficit management, exchange‑rate stability, and the broader financial‑inclusion agenda embodied in PM‑Kisan and PM‑GKY schemes.

📋 Classification: Transmission‑Failure Drivers

CategoryDescription
Liquidity‑Supply GapExcess RBI reserves, with 42 % idle in SLR accounts, do not translate into loan growth.
Credit‑Allocation TensionHigh non‑performing assets (>7 % of advances) blunt the impact of repo‑rate cuts.
Market‑Depth DeficiencyCorporate bonds represent only 0.3 % of market value, far below the 5 % benchmark for effective portfolio rebalancing.
Policy‑Induced RigiditySLR‑driven balance‑sheet constraints limit banks’ ability to expand credit, as highlighted by the IBA.

📊 Quick Reference: Transmission of Monetary Policy

AspectDetail
Definition (RBI)Process by which changes in the policy rate affect the economy via interest rates, asset prices, exchange rates, and aggregate demand (RBI Monetary Policy Report 2023‑24).
Statutory DutyRBI Act 1934, Section 7 assigns the duty to formulate monetary policy.
MPC CreationRBI (Amendment) Act 2016, Section 2 establishes the Monetary Policy Committee.
MPC MandateThe MPC is tasked with setting the repo (policy) rate.
Transmission Stages1) Policy‑rate adjustment by the MPC; 2) Propagation through money‑market rates, credit conditions, and asset‑price channels; 3) Impact on aggregate demand, output, and inflation.
Distinction from Fiscal PolicyFiscal‑policy transmission relies on government spending and taxation, not interest‑rate adjustments.
Distinction from Direct Credit AllocationDirect credit‑allocation schemes bypass market‑determined rates, unlike monetary‑policy transmission.
Empirical Link (2022‑23)A 100‑basis‑point repo‑rate cut is associated with a 0.25‑percentage‑point rise in private‑sector credit growth (Economic Survey 2022‑23).
Key InsightA modest 100‑basis‑point reduction in the repo rate can stimulate private‑sector credit growth by a quarter of a percentage point.
Channels IdentifiedInterest‑rate, asset‑price, exchange‑rate, and credit‑condition channels.
