1.2 Structure of Indian Securities Markets & Participants

Key Takeaways

  • The Indian securities market is structurally divided into the Primary Market (where issuers mobilize fresh capital) and the Secondary Market (where outstanding securities trade among investors).

  • Primary market capital issuance mechanisms include Initial Public Offerings (IPOs), Follow-on Public Offerings (FPOs), Rights Issues, Private Placements, and Qualified Institutions Placements (QIPs).

  • Key financial asset classes in India comprise Equities, Fixed Income/Debt instruments (G-Secs, SDLs, T-Bills, and Corporate Bonds), and exchange-traded Derivatives (Futures and Options).

  • Market Infrastructure Institutions (MIIs) provide critical structural integrity: Stock Exchanges match orders, Clearing Corporations guarantee settlement through novation, and Depositories (NSDL and CDSL) maintain dematerialized ownership.

1.2 Structure of Indian Securities Markets & Participants

Quick Answer: The Indian capital market consists of the Primary Market (where corporate entities and governments raise capital by issuing new securities) and the Secondary Market (where previously issued securities are traded among investors on exchanges like NSE and BSE). Core asset classes include equities, fixed income debt (G-Secs, T-Bills, corporate bonds), and derivatives. Market integrity is upheld by specialized institutions: clearing corporations act as central counterparties, depositories safeguard electronic records, and SEBI regulates all intermediaries.


The Dual Market Architecture: Primary vs. Secondary Markets

The securities market in India performs two indispensable macroeconomic functions: mobilizing domestic and global savings into productive economic enterprises, and providing continuous liquidity to investors. This dual architecture is split into primary and secondary markets:

The Primary Market (New Issues Market)

The Primary Market is the venue where securities are created and offered to the investing public for the very first time. In a primary issuance, transactions take place directly between the issuer (a corporation or government) and investors. The primary economic hallmark of this market is that proceeds flow directly to the issuing entity (except in an Offer for Sale, where proceeds flow to exiting promoters or private equity investors) to fund business expansion, debt reduction, infrastructure projects, or working capital.

The Secondary Market (Stock Exchanges)

Once securities are allotted in the primary market and formally listed, they transition to the Secondary Market. The secondary market consists of recognized nationwide stock exchanges where investors buy and sell existing securities amongst themselves. Crucially, the issuing corporate entity receives zero financial proceeds from secondary market transactions. Instead, the secondary market provides liquidity, continuous price discovery, and exit avenues for investors, which in turn gives investors the confidence to supply fresh capital in primary issuances.


Primary Market Capital Raising Mechanisms

Indian corporate law and SEBI regulations provide distinct capital-raising routes tailored to the issuer's maturity, capital requirements, and target investor base:

  1. Initial Public Offering (IPO): An unlisted company's first public offering of securities to institutional and retail investors, leading to a listing on stock exchanges. An IPO can consist of a Fresh Issue (issuing new shares to raise fresh equity) or an Offer for Sale (OFS) (existing promoters or venture capital funds selling their existing shares to the public without adding new capital to the company's balance sheet).
  2. Follow-on Public Offering (FPO): A public issuance of additional shares by an already listed company to raise further equity capital.
  3. Rights Issue: An offer of new equity shares to the company's existing shareholders in proportion to their existing shareholding (governed by Section 62 of the Companies Act, 2013). Shareholders receive rights entitlements (REs) that can be exercised or renounced and traded on the stock exchange.
  4. Preferential Allotment: An issue of shares or convertible securities to a selected group of persons (not through a public offer or rights issue) under Section 62(1)(c) read with Section 42 of the Companies Act, 2013 and, for listed companies, the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (ICDR Regulations).
  5. Qualified Institutions Placement (QIP): A private placement mechanism allowing listed Indian companies to issue equity shares or convertible debentures exclusively to Qualified Institutional Buyers (QIBs) without preparing a lengthy, time-consuming public prospectus.
  6. Bonus Issue: Capitalization of free reserves or securities premium accounts into fully paid-up equity shares distributed to existing shareholders at zero cash cost in a specified ratio (e.g., 1:1 or 2:1), leaving enterprise value and proportional ownership unchanged.

Key Financial Asset Classes in the Indian Ecosystem

Securities research entities analyze and publish reports across multiple distinct asset classes, each characterized by distinct risk-return profiles:

1. Equities

Equity shares represent fractional residual ownership in a corporate enterprise. Equity investors are entitled to voting rights at shareholder meetings and may receive dividends declared by the board of directors. Equities bear residual risk: in the event of liquidation, equity shareholders are paid only after all secured and unsecured creditors, debenture holders, and preference shareholders are settled in full. Some companies also issue shares with Differential Voting Rights (DVRs), which carry different voting rights (and sometimes different dividend rights) from ordinary equity shares.

2. Fixed Income & Debt Instruments

Fixed income instruments represent contractual loan obligations where the borrower agrees to pay specified periodic coupon interest and return principal upon maturity:

  • Central Government Securities (G-Secs): Sovereign debt instruments issued by the Reserve Bank of India (RBI) on behalf of the Government of India. With maturities extending up to 50 years (the government first issued a 50-year bond in 2023), G-Secs carry practically zero credit default risk (sovereign guarantee).
  • State Development Loans (SDLs): Debt securities issued by state governments to fund infrastructure and budgetary expenditure, priced at a small spread over Central G-Secs.
  • Treasury Bills (T-Bills): Short-term sovereign money market instruments issued by the RBI for tenors of 91 days, 182 days, and 364 days. T-Bills pay no periodic coupon; they are issued at a discount to nominal face value and redeemed at par (₹100), with the discount reflecting the investor's yield.
  • Corporate Bonds & Debentures: Debt instruments issued by private and public corporations. They may be secured by fixed corporate charges or unsecured. Rated by credit rating agencies from AAA (highest safety) down to D (in default).
  • Commercial Paper (CP): Short-term unsecured promissory notes issued by highly rated corporations to fund seasonal or working capital requirements, with maturities ranging from 7 days up to 1 year.

3. Derivatives Contracts

Derivatives are financial instruments whose contract value is derived from an underlying asset, such as an equity stock, an equity index, a commodity, or a currency:

  • Futures Contracts: Legally binding, standardized exchange-traded agreements to buy or sell a specified quantity of the underlying asset at an agreed price on a future expiration date. Futures require initial and maintenance margin deposits and are subject to daily Mark-to-Market (MTM) cash settlement.
  • Options Contracts: Contracts that grant the buyer the right, but not the obligation, to buy (Call Option) or sell (Put Option) an underlying asset at an agreed strike price on or before expiration. In India, equity index options (such as NIFTY 50 and BSE SENSEX options) are traded as European style contracts (exercisable only on expiration day) and are settled entirely in cash.

Indian Securities Market Architecture & Trade Lifecycle

Core Market Intermediaries & Infrastructure Institutions

The seamless functioning of the Indian capital market relies on specialized institutional participants operating under SEBI's regulatory oversight:

1. Stock Exchanges

Recognized stock exchanges—chiefly the National Stock Exchange of India (NSE) and BSE Limited (BSE)—provide the automated, screen-based order matching infrastructure. Exchanges are demutualized entities, meaning their ownership, management, and trading privileges are legally separated to eliminate structural conflicts of interest.

2. Clearing Corporations

NSE Clearing Limited (formerly NSCCL) and Indian Clearing Corporation Limited (ICCL) are specialized Market Infrastructure Institutions (MIIs) that manage post-trade operations. The clearing corporation acts as a Central Counterparty (CCP) through the legal doctrine of novation: it interposes itself between the buyer and seller, becoming the legal seller to every buyer and the buyer to every seller. By guaranteeing financial settlement, clearing corporations eliminate bilateral counterparty default risk.

3. Depositories & Depository Participants

Physical share certificates have been replaced by electronic records maintained by two national depositories:

  • National Securities Depository Limited (NSDL) (promoted by IDBI, UTI, and NSE);
  • Central Depository Services (India) Limited (CDSL) (promoted by BSE and leading banks).

Depositories hold securities in fungible dematerialized (demat) accounts. Investors interface with depositories through registered Depository Participants (DPs), such as banks and stockbrokers, who act as retail branch agents.

4. Stockbrokers & Clearing Members

Stockbrokers are registered trading members of an exchange who facilitate order routing and trade execution for clients. Clearing members take on the financial responsibility of settling trades with the clearing corporation.

5. Merchant Bankers (Investment Bankers)

Merchant bankers registered under SEBI regulations manage public offerings. They perform due diligence on corporate issuers, draft draft red herring prospectuses (DRHP), structure pricing, coordinate underwriting syndicates, and oversee listing formalities.

6. Custodians

Custodians are financial institutions responsible for the safekeeping of securities and settlement of transactions for institutional clients (such as FPIs, mutual funds, and pension funds). They track corporate actions, dividend credits, and tax withholdings.


Categorization of Market Investors

SEBI classifies market participants into three primary categories to calibrate regulatory protections, allocation quotas in public offerings, and disclosure standards:

Investor CategoryDefinition & EligibilityPublic Offer Allocation Quota (Typical)
Retail Individual Investors (RIIs)Individuals, including HUFs and NRIs, who apply for securities valued at ₹2,00,000 or less in a public issue.Minimum 35% in standard profitability-route IPOs
Non-Institutional Investors (NIIs / HNIs)High-net-worth individuals, family trusts, and corporate treasuries applying for amounts exceeding ₹2,00,000.Minimum 15% in standard IPOs (sub-divided into small and big HNI buckets)
Qualified Institutional Buyers (QIBs)Professional institutional entities recognized by SEBI: Mutual Funds, Insurance Companies, Banks, Pension Funds, AIFs, and registered FPIs.Maximum 50% in standard IPOs (with up to 60% of QIB portion allocable to Anchor Investors)

Institutional investors are further classified by origin:

  • Domestic Institutional Investors (DIIs): Indian mutual funds, insurance corporations (e.g., LIC), national pension funds, and domestic Alternative Investment Funds (AIFs Category I, II, and III).
  • Foreign Portfolio Investors (FPIs): Entities incorporated outside India (sovereign wealth funds, foreign mutual funds, endowment funds) registered under the SEBI (Foreign Portfolio Investors) Regulations to trade in Indian securities.
