Chapter 4: Market Infrastructure Institutions (MIIs) and Market Intermediaries in the Securities Market
Informational Overview: Institutional Backbone of the Securities Market
The Indian securities market relies on a robust structural framework composed of two primary pillars: Market Infrastructure Institutions (MIIs) and Market Intermediaries. Together, these entities provide the technological platform, clearing mechanism, custodial services, and operational support necessary to facilitate primary market fundraising and secondary market trading in a fair, transparent, and efficient manner.
Market Infrastructure Institutions (MIIs)
What are Market Infrastructure Institutions?
Market Infrastructure Institutions (MIIs) provide the core infrastructure required to facilitate end-to-end transactions—including the issuance, purchase, and sale of financial securities—in the securities market. They function as the underlying operational backbone for the entire financial system.
The Three Pillars of MIIs
MIIs are categorized into three major institutional entities:
- Stock Exchanges: Provide a nationwide, computerized, screen-based trading platform that enables investors to buy and sell securities through registered stockbrokers at market-determined prices in a fair and orderly manner.
- Clearing Corporations: Facilitate the clearing and settlement of trades executed on stock exchange platforms, ensuring counterparty guarantee and risk management.
- Depositories: Hold securities in electronic/demat format and enable smooth transfer of ownership upon trade settlement.
Major Nation-wide Stock Exchanges in India
The major recognized nation-wide stock exchanges operating in India include:
- BSE Limited (BSE)
- National Stock Exchange of India Limited (NSE)
- Metropolitan Stock Exchange of India Limited (MSEI)
Market Intermediaries in the Securities Market
Role and Mandatory Regulatory Oversight
Market Intermediaries play a vital role in ensuring the efficient functioning of both the primary market (where new securities are issued) and the secondary market (where existing securities are traded). They execute buy and sell orders, undertake securities transactions, and supply critical market information supporting investment activity.
- Mandatory SEBI Registration: All securities market intermediaries must be registered with the Securities and Exchange Board of India (SEBI).
- Regulatory Compliance: Intermediaries are legally obligated to comply with SEBI-prescribed regulations designed specifically to safeguard investor interests and maintain market integrity.
Key Intermediaries & Their Core Functions
1. Stockbroker
- Definition: A stockbroker is an entity registered with SEBI and a trading member of a recognized stock exchange permitted to execute trades on stock exchange platforms.
- Remuneration: Stockbrokers charge a fee or brokerage commission for executing buy or sell orders on behalf of investors.
- Functions: Facilitates order placement, client onboarding, trade execution, margin collection, and contract note issuance.
2. Authorized Person (AP)
- Definition: An Authorized Person is not a member of a stock exchange, but an agent appointed by a stockbroker (including trading members) to provide investors access to the exchange trading platform.
- Eligible Structures: An Authorized Person can be an individual, partnership firm, Limited Liability Partnership (LLP), or body corporate.
3. Depository Participant (DP)
- Definition: A Depository Participant (DP) acts as an agent of the depository (such as NSDL or CDSL) and serves as the direct interface between the depository and the investor.
- Functions: Opens and maintains Demat accounts, holds securities electronically, facilitates dematerialization, and executes share transfers/pledges.
4. Registrar and Transfer Agent (RTA)
- Definition: Registrars and Transfer Agents (RTAs) are service entities that maintain detailed records of investor transactions and security ownership details.
- Clients Served: RTAs perform these record-keeping duties on behalf of companies issuing shares/bonds and fund houses (mutual funds).
5. Other Key Intermediaries Mentioned in the Framework
- Merchant Bankers: Facilitate primary market capital raising and issue management for public offers.
- Share Transfer Agents: Manage security transfer details for corporate issuers.

Commercial & Transactional Workflow
When an investor buys or sells securities in the market, MIIs and Intermediaries work in tandem across the transaction lifecycle:

- Order Initiation: The investor places a buy or sell order through a SEBI-registered Stockbroker or Authorized Person.
- Order Execution: The stockbroker routes the trade to the Stock Exchange (MII), where automated screen-based matching takes place at market-determined prices.
- Clearing & Settlement: The Clearing Corporation (MII) handles net settlement of funds and securities.
- Securities Transfer: The Depository Participant (DP) credits or debits securities in the investor's electronic Demat account maintained with the Depository (MII).
- Record Maintenance: The RTA updates ownership records on behalf of the issuer company or fund house.
Formula Rules Representation
For brokerage and fee calculation on trades (expressed in simple linear line format as required):
- Total Transaction Cost = Trade Execution Value + Brokerage Fee + Applicable Taxes and Statutory Levies
- Net Payable per Buy Trade = Trade Price per Share * Number of Shares + Brokerage Charges + Applicable Taxes
- Net Receivable per Sell Trade = Trade Price per Share * Number of Shares - Brokerage Charges - Applicable Taxes
