    RBI draft norms on Capital Market Exposure (CME)

    Why in the News?

    The Reserve Bank of India released draft “Capital Market Exposure Directions, 2025” to overhaul rules on banks’ exposure to capital markets.

    What is Capital Market Exposure (CME)?

    It simply means how much a bank is involved in the stock market and related financial activities.

    When banks deal with the capital market, they can do this in two main ways:

    1. Direct Exposure: When the bank itself invests in shares, bonds, or mutual funds, just like an investor would. Example: if a bank buys shares of a company or invests in government bonds, that’s direct exposure.
    2. Indirect Exposure: When the bank gives loans linked to the stock market, for example, lending money to stockbrokers, mutual funds, or investors who want to buy shares.

    Because the stock market goes up and down, these activities are riskier than normal banking (like giving home or business loans). So, the Reserve Bank of India (RBI) keeps a close watch and sets limits on how much banks can invest or lend in the capital market.

    About Draft Norms on Capital Market Exposure, 2025:

    • Objective: To modernise, unify, and simplify rules on banks’ capital-market lending and investment exposures.
    • Expanded Scope: Permits acquisition-finance lending for corporates and higher credit limits for individuals participating in Initial Public Offerings (IPOs), Follow-on Public Offerings (FPOs), and Employee Stock Option Plans (ESOPs).

    Key Features of the Draft CME Norms:

    • Exposure Limits:
      • Direct exposure (investments + acquisition finance) capped at 20 percent of Tier-1 capital on solo and consolidated bases.
      • Aggregate exposure (direct + indirect) capped at 40 percent of consolidated Tier-1 capital.
    • Acquisition Finance:
      • Banks may finance up to 70 percent of acquisition cost, with borrowers contributing 30 percent equity from own funds.
      • Permitted only for listed companies with sound financials and independent valuations compliant with Securities and Exchange Board of India (SEBI) norms.
      • Aggregate acquisition-finance exposure limited to 10 percent of Tier-1 capital; not allowed for Non-Banking Financial Companies (NBFCs), Alternative Investment Funds (AIFs), or related parties.
    • Individual Market-Participation Loans:
      • Maximum loan per individual increased to ₹ 25 lakh; up to 75 percent of subscription value may be financed with a 25 percent margin.
      • Shares allotted under IPOs, FPOs, or ESOPs must be pledged and lien-marked to the lending bank.
    • Loans Against Securities:
      • Capped at ₹ 1 crore per individual for eligible securities (government securities, mutual-fund units, listed shares, or high-rated corporate debt).
      • Banks must maintain prudent LTV ratios and adopt internal risk-control systems for valuation and monitoring.

    Need for Such Norms:

    • Modernisation: Replaces fragmented rules with a unified prudential framework.
    • Corporate Expansion: Enables M&A financing, supporting Indian firms’ global competitiveness.
    • Retail Participation: Encourages individual investment and deepens equity-market access.
    • Risk Containment: Exposure caps and buffers ensure stability and discipline in bank lending.
    • Global Alignment: Harmonises with Basel III and international acquisition-finance standards.
    • Economic Impact: Enhances financial depth, liquidity, and investment-led growth in capital markets.

    Kerala will be officially declared free from extreme poverty on November 1st, marking a national first in poverty eradication.

    To assess this, Kerala relied on NITI Aayog’s assessment of Kerala using its Multidimensional Poverty Index (MPI).

    What is Extreme Poverty?

    • Overview: According to the World Bank, extreme poverty is defined as living on less than $2.15 per day (2017 Purchasing Power Parity), representing absolute deprivation.
    • Revised Thresholds: In 2025, the World Bank updated the extreme poverty benchmark to $3/day (PPP 2021) for low-income countries, reflecting inflation and rising living costs.
    • Measurement Basis: It uses Purchasing Power Parity (PPP) to compare cost of living across countries and Household Consumption Expenditure Survey (HCES) data as a proxy for income.
    • Nature: Extreme poverty signifies absolute poverty, unlike relative poverty, which measures inequality within societies.
    • Indicators: It encompasses lack of access to essentials such as food security, safe housing, healthcare, education, clean water, and sanitation.

    Extreme Poverty in India:

    • Overview: India has achieved major success in reducing extreme poverty through inclusive growth and welfare-based redistribution over the past decade.
    • Global Benchmark: As per the World Bank (2025), India’s extreme poverty rate declined from 27.1% (2011–12) to 5.3% (2022–23), among the fastest reductions globally.
    • Population Impact: Nearly 270 million people were lifted out of extreme poverty; those living below the $3/day threshold fell from 344 million to 75 million.
    • Rural Transformation: The decline was steeper in rural India, supported by flagship programmes like MGNREGA, PM Awas Yojana, National Food Security Act (NFSA), and Ayushman Bharat.
    • Social Protection Role: Expansion of direct benefit transfers (DBT), PDS coverage, and rural employment improved income security and consumption stability.

    What has Kerala achieved?

    • Milestone: Kerala has been officially declared free from extreme poverty as of November 1, 2025, becoming the first Indian state to achieve this feat.
    • Programme Launch: The Extreme Poverty Eradication Programme began in 2021, following one of the first Cabinet decisions of the Left Democratic Front (LDF) government.
    • Scale: Out of 64,006 families identified as extremely poor, 59,277 families have been uplifted after targeted interventions across housing, health, and livelihoods.
    • Interventions:
      • Houses built for 3,913 families and land allotted to 1,338 families.
      • Repairs up to ₹2 lakh provided for 5,651 homes.
      • Essential documents like ration and Aadhaar cards issued to 21,263 individuals.
    • Methodology: Each family was covered through a micro plan, integrating state welfare schemes and social audits with geo-tagged verification.
    • Outcome: Kerala now has 0% extreme poverty, aligning with UN Sustainable Development Goal (SDG 1) to eradicate poverty by 2030.
    • Significance: The achievement demonstrates Kerala’s model of inclusive governance, where local bodies, irrespective of political control, collaborated to ensure last-mile welfare delivery.
