Introduction

A market participant is any individual, institution or body that takes part in the creation, trading, clearing, settlement or regulation of securities. In the Indian context, participants range from retail investors buying equity shares to large institutions issuing bonds, and from brokers executing trades to SEBI overseeing market conduct.

The classification of participants matters because each group is subject to distinct regulatory requirements, risk‑management obligations and reporting standards. For example, an issuer must comply with prospectus filing norms, while a broker must maintain a net‑worth requirement and adhere to KYC norms. Knowing these distinctions helps you eliminate wrong answer choices that mix up duties of different players.

Exam questions often present a scenario and ask which participant is responsible for a specific action – such as filing a prospectus, maintaining a depository account, or supervising market integrity. By memorising the core categories and their key functions, you can quickly map the scenario to the correct participant.

The primary participants can be grouped into four broad categories: Investors, Issuers, Intermediaries and Regulators. Investors include retail traders, high‑net‑worth individuals, mutual funds, pension funds and foreign portfolio investors. Their main interest is to buy or sell securities for capital appreciation or income.

Issuers are entities that raise capital by offering securities – corporations issuing equity or debentures, banks issuing bonds, and the government issuing treasury bills. They must comply with disclosure norms, prospectus filing, and post‑issue reporting as prescribed by SEBI and the Companies Act.

Intermediaries bridge the gap between investors and issuers. They encompass stockbrokers, sub‑brokers, depositories (NSDL, CDSL), clearing corporations, and mutual fund distributors. Their responsibilities include order execution, settlement, custodial services and client onboarding. Regulators such as SEBI, the Reserve Bank of India (RBI) and the respective stock exchanges oversee the conduct of these intermediaries.

Broker‑Dealers are the most visible intermediaries. They receive client orders, route them to exchanges, and earn commissions or brokerage fees. Under SEBI (Stock Brokers) Regulations, they must maintain a minimum net‑worth and adhere to strict KYC and AML procedures.

Depositories (NSDL and CDSL) hold securities in electronic form, eliminating physical certificates. They enable smooth dematerialisation, settlement and corporate actions. A depository participant (DP) acts as the link between the investor and the depository, similar to a bank‑account relationship.

Clearing Corporations such as the National Securities Clearing Corporation (NSCCL) guarantee trade settlement, manage default risk and maintain a settlement guarantee fund. They calculate net positions, perform multilateral netting and ensure that cash and securities flow correctly on the settlement day.

The Securities and Exchange Board of India (SEBI) is the primary regulator for securities markets. It frames regulations for issuers, intermediaries and market conduct, and has the power to impose penalties, suspend trading and conduct inspections. SEBI’s key regulations include the SEBI (Prohibition of Insider Trading) Regulations and the SEBI (Stock Brokers) Regulations.

The Reserve Bank of India (RBI) indirectly influences the securities market through its oversight of banks, foreign exchange, and certain mutual fund activities. For instance, RBI guidelines govern the investment limits of banks in corporate bonds and the operation of non‑banking financial companies (NBFCs) that act as market participants.

Stock exchanges like the Bombay Stock Exchange (BSE) and National Stock Exchange (NSE) also function as self‑regulatory organisations (SROs). They enforce listing requirements, monitor trading anomalies and maintain market surveillance systems. Understanding which body governs which activity is a frequent exam focus.

Each participant’s responsibilities tie directly to risk management. Issuers must disclose material information to avoid insider‑trading violations; brokers must maintain adequate capital to absorb market‑risk losses; depositories must ensure the integrity of electronic holdings; and regulators must monitor compliance to safeguard market integrity.

From an operational perspective, knowing who does what helps you answer scenario‑based questions. For example, if a client’s trade fails to settle, the clearing corporation is the first point of investigation, not the broker. Similarly, a breach of prospectus filing norms points to the issuer, not the stock exchange.

Examiners test this knowledge by presenting a chain of events and asking which participant is accountable for a specific control or breach. Memorise the key duty of each participant and link it to the relevant regulatory provision for quick recall.
