Capital Market, SEBI and Stock Exchanges in India
Complete notes on the Indian capital market for exams: primary and secondary markets, SEBI and its powers, BSE and NSE, Sensex and Nifty, depositories and key terms.

Every economy needs a place where savings meet investment. In India that place is the financial market, and it has two halves. The money market handles short-term funds, up to one year, through instruments such as treasury bills, commercial paper and certificates of deposit, and the Reserve Bank of India regulates it. The capital market handles long-term funds through shares, debentures and bonds, and the Securities and Exchange Board of India regulates it. This division, and the two regulators attached to it, is the first thing an examiner checks.
The two segments of the capital market
The primary market is where securities are issued for the first time and money moves from investors to the company. A company going to the public for the first time makes an Initial Public Offering; a listed company raising more capital from the public makes a Follow-on Public Offer; an offer restricted to existing shareholders is a rights issue; and an issue to a few selected institutions is a private placement or a qualified institutional placement. The secondary market is where securities already issued change hands between investors, and no money reaches the company; this is the stock exchange. The primary market creates the security, the secondary market gives it liquidity, and a healthy primary market depends on the secondary one.
Securities and Exchange Board of India
SEBI was set up in April 1988 as an administrative body without statutory force. It became a statutory regulator through the Securities and Exchange Board of India Act, 1992, passed in the year of the securities scam that exposed how weak supervision had been. Its headquarters is in Mumbai, at the Bandra Kurla Complex, with regional offices at New Delhi, Kolkata, Chennai and Ahmedabad. The preamble of the Act states three objectives: to protect the interests of investors in securities, to promote the development of the securities market, and to regulate it. The Board consists of a Chairman, two members from the ministries of the Union Government dealing with finance and company law, one member from the Reserve Bank of India, and five members appointed by the Union Government; the Chairman and the members are appointed by the Government.
SEBI is described as a quasi-legislative, quasi-executive and quasi-judicial body, because it frames regulations, investigates and inspects, and passes orders imposing penalties. It registers and regulates stock brokers, merchant bankers, depositories, mutual funds and credit rating agencies, prohibits insider trading and fraudulent or unfair trade practices, and lays down disclosure norms for public issues. An appeal against a SEBI order goes to the Securities Appellate Tribunal, and from the Tribunal to the Supreme Court on a question of law. The regulation of commodity derivatives was brought under SEBI when the Forward Markets Commission was merged into it in 2015.
The stock exchanges and their indices
The Bombay Stock Exchange was founded in 1875 as the Native Share and Stock Brokers' Association and is the oldest stock exchange in Asia; it stands on Dalal Street in Mumbai. Its benchmark index, the Sensex, is made up of thirty of the largest and most actively traded companies, with 1978-79 as its base year and a base value of 100. The National Stock Exchange was incorporated in 1992 on the recommendation of the Pherwani Committee and began trading in 1994; it was the first exchange in India to offer fully screen-based electronic trading, which ended the open outcry system and the regional monopolies of brokers. Its benchmark index is the Nifty 50, with 1995 as its base year and a base value of 1000.
| Feature | BSE | NSE |
|---|---|---|
| Established | 1875 | Incorporated 1992, trading from 1994 |
| Location | Dalal Street, Mumbai | Mumbai |
| Benchmark index | Sensex, 30 companies | Nifty 50, 50 companies |
| Base year of index | 1978-79, base value 100 | 1995, base value 1000 |
| Note | Oldest exchange in Asia | First fully electronic exchange in India |
Depositories, dematerialisation and the law
Shares are no longer held as paper certificates. Under the Depositories Act, 1996 they are held in electronic form in a demat account, and two depositories keep those records: the National Securities Depository Limited, set up in 1996 as the first depository in India, and the Central Depository Services Limited, which followed in 1999. An investor deals with a depository participant, usually a bank or a broker, rather than with the depository directly. Trading itself is governed by the Securities Contracts (Regulation) Act, 1956, which defines securities and provides for the recognition of stock exchanges, while the Companies Act governs the issue of shares by a company.
The vocabulary of the market
- A bull is an investor who expects prices to rise; a bear expects them to fall. A rising market is a bull market and a falling one a bear market.
- Market capitalisation is the price of a share multiplied by the number of shares issued, and it decides whether a company is called large cap, mid cap or small cap.
- Book building is the process of discovering the issue price from the bids received, instead of fixing it in advance.
- A circuit breaker halts trading when an index moves beyond a set percentage, to stop panic from feeding on itself.
- Insider trading is dealing in a security on the strength of unpublished price-sensitive information, and it is an offence under SEBI regulations.
- Depositary receipts let a company raise money abroad: an American Depositary Receipt is issued in the United States and a Global Depositary Receipt in other foreign markets, while an Indian Depositary Receipt lets a foreign company raise money here.
Examiners also expect the names of the credit rating agencies that assess debt instruments, CRISIL, ICRA and CARE among them, and an awareness that SEBI runs a complaint redress platform for investors and maintains an Investor Protection Fund.
Exam Point of View
Banking and SSC papers ask the founding years first: BSE 1875, SEBI as an administrative body in 1988 and as a statutory body in 1992, NSE 1992 with trading from 1994, NSDL 1996, CDSL 1999 and the FMC merger in 2015. The second favourite is the index pair: Sensex with 30 companies, base 1978-79 and base value 100, against Nifty 50 with base 1995 and base value 1000. Expect questions on which regulator looks after which market, on the appellate route to the Securities Appellate Tribunal, and on the difference between an IPO, an FPO, a rights issue and a private placement. Terms such as bull, bear, book building, circuit breaker, insider trading, ADR and GDR are asked directly.

Practice MCQs on this topic
In which of the following years was the Securities and Exchange Board of India (SEBI) established by the government of India to protect the interests of investors in securities and to promote and regulate the securities market?
- A.1992
- B.1999
- C.1987
- D.1985
Show answer
Correct answer: A. 1992
Explanation
The correct answer is A, 1992. SEBI first appeared in April 1988 as an administrative arrangement with no legal powers, and it became a statutory regulator when the Securities and Exchange Board of India Act was passed in 1992; the words quoted in the question are taken from the preamble of that Act, which speaks of protecting investors, promoting the development of the securities market and regulating it. Because the statutory body dates from the Act, 1992 is the year every examination expects. Option B, 1999, is the year the Central Depository Services Limited was set up, the second depository in India. Option C, 1987, and option D, 1985, come before even the administrative body existed. Keep the sequence in mind: the Securities Contracts (Regulation) Act of 1956, SEBI as an administrative body in 1988, the SEBI Act in 1992 and the Depositories Act in 1996.
Which is the oldest stock exchange in Asia?
- A.National Stock Exchange
- B.Bombay Stock Exchange
- C.Calcutta Stock Exchange
- D.Madras Stock Exchange
Show answer
Correct answer: B. Bombay Stock Exchange
Explanation
The correct answer is B, the Bombay Stock Exchange. It was founded in 1875 as the Native Share and Stock Brokers’ Association, grew out of brokers meeting under a banyan tree in Bombay, and is the oldest stock exchange in Asia; it now stands on Dalal Street and its benchmark index is the Sensex. Option A, the National Stock Exchange, was incorporated only in 1992 and began trading in 1994, though it was the first in India to offer fully screen-based electronic trading. Option C, the Calcutta Stock Exchange, was established in 1908 and is the second oldest in the country, which makes it the most tempting distractor. Option D, the Madras Stock Exchange, came later still and is one of the regional exchanges that lost business once electronic trading made a nationwide market possible.
How many companies make up the BSE Sensex?
- A.20
- B.30
- C.50
- D.100
Show answer
Correct answer: B. 30
Explanation
The correct answer is B, 30. The Sensex, or Sensitive Index, of the Bombay Stock Exchange is built from thirty large, well established and actively traded companies drawn from the main sectors of the economy, and it is weighted by free-float market capitalisation. Option A, 20, matches no Indian benchmark index. Option C, 50, is the number of companies in the Nifty 50 of the National Stock Exchange, and swapping the two is the standard error in this question. Option D, 100, is the size of broader indices such as the Nifty 100 and the older BSE 100. Two more facts are asked with this one: the base year of the Sensex is 1978-79 with a base value of 100, while the Nifty 50 has 1995 as its base year with a base value of 1000.
The base year of the BSE Sensex is:
- A.1950-51
- B.1978-79
- C.1993-94
- D.2011-12
Show answer
Correct answer: B. 1978-79
Explanation
The correct answer is B, 1978-79. The Sensex was compiled backwards to 1978-79 and that year was given a base value of 100, so the index number states how many times the market value of its thirty constituents has grown since then. Option A, 1950-51, is the base year long used for national income series, not for a share index, and it is a favourite distractor because students remember it from the national income chapter. Option C, 1993-94, and option D, 2011-12, are base years used at different times for the Index of Industrial Production and the wholesale and consumer price series, which is exactly why they appear here. Remember the pair: Sensex 1978-79 with base 100, Nifty 50 with 3 November 1995 as its base date and base value 1000.
The money market in India is regulated by which authority?
- A.SEBI
- B.The Reserve Bank of India
- C.The Ministry of Corporate Affairs
- D.IRDAI
Show answer
Correct answer: B. The Reserve Bank of India
Explanation
The correct answer is B, the Reserve Bank of India. The money market deals in short-term funds of up to one year, through treasury bills, commercial paper, certificates of deposit and call money, and the Reserve Bank regulates it as part of its control over credit and liquidity. Option A, SEBI, regulates the capital market, where long-term funds are raised through shares, debentures and bonds, and the question sets the two against each other on purpose. Option C, the Ministry of Corporate Affairs, administers company law, including the issue of shares by a company, but it is not a market regulator. Option D, the Insurance Regulatory and Development Authority of India, regulates insurers. Where a product straddles both markets, such as a corporate bond, the two regulators work under an agreed division of responsibility.
An appeal against an order passed by SEBI lies to:
- A.The High Court of the state concerned
- B.The Securities Appellate Tribunal
- C.The National Company Law Tribunal
- D.The Reserve Bank of India
Show answer
Correct answer: B. The Securities Appellate Tribunal
Explanation
The correct answer is B, the Securities Appellate Tribunal. A person aggrieved by an order of SEBI may appeal to the Tribunal, which is provided for by the SEBI Act itself, and from the Tribunal a further appeal lies to the Supreme Court on a question of law. This ladder is what makes SEBI a quasi-judicial body: it passes orders that are appealable rather than final. Option A is wrong because a writ petition to a High Court is an extraordinary remedy, not the appeal the Act provides. Option C, the National Company Law Tribunal, hears matters under company law and insolvency, including mergers and oppression cases, not securities market appeals. Option D is wrong because the Reserve Bank is a separate regulator with no appellate authority over SEBI; the two supervise different segments of the financial market.
When a company offers its shares to the public for the first time, the issue is called:
- A.A rights issue
- B.A follow-on public offer
- C.An initial public offering
- D.A private placement
Show answer
Correct answer: C. An initial public offering
Explanation
The correct answer is C, an initial public offering. An IPO is the first sale of shares by a company to the general public, after which the shares are listed and traded on a stock exchange; it belongs to the primary market, because the money raised goes to the company itself. Option A, a rights issue, is an offer of new shares made only to existing shareholders, usually in proportion to their holding and at a stated price. Option B, a follow-on public offer, is a further issue to the public by a company that is already listed, so it cannot be the first one. Option D, a private placement, is an issue to a small number of selected investors, often financial institutions, without a public offer; when the investors are qualified institutional buyers it is called a qualified institutional placement.
The headquarters of SEBI is located in which city?
- A.New Delhi
- B.Mumbai
- C.Kolkata
- D.Chennai
Show answer
Correct answer: B. Mumbai
Explanation
The correct answer is B, Mumbai. SEBI has its head office in Mumbai, at the Bandra Kurla Complex, which places the regulator in the same city as the Bombay Stock Exchange, the National Stock Exchange and the Reserve Bank of India, making Mumbai the financial capital of the country. Options A, C and D are wrong as the head office, but each is a regional office of SEBI: New Delhi for the northern region, Kolkata for the eastern region and Chennai for the southern region, with Ahmedabad serving the west. Questions sometimes ask which of the four is not a regional office, so learn all four together. Note also that the Board has a Chairman, two members from Union ministries dealing with finance and company law, one member from the Reserve Bank and five members appointed by the Union Government.
Which Act provides for the recognition and regulation of stock exchanges in India?
- A.The Securities Contracts (Regulation) Act, 1956
- B.The Banking Regulation Act, 1949
- C.The Depositories Act, 1996
- D.The FEMA, 1999
Show answer
Correct answer: A. The Securities Contracts (Regulation) Act, 1956
Explanation
The correct answer is A, the Securities Contracts (Regulation) Act, 1956. It defines what a security is, provides for the recognition of stock exchanges by the Government, and lays down the framework within which contracts in securities may be made; it is the oldest of the statutes governing this market and still the basic one. Option B, the Banking Regulation Act of 1949, governs banking companies and the powers of the Reserve Bank over them. Option C, the Depositories Act of 1996, allows securities to be held and transferred in electronic form and provides for depositories such as NSDL and CDSL, but not for the recognition of exchanges. Option D, the Foreign Exchange Management Act of 1999, governs dealings in foreign exchange and replaced the earlier and far stricter FERA of 1973.
Which was the first depository established in India?
- A.CDSL
- B.NSDL
- C.NSCCL
- D.CCIL
Show answer
Correct answer: B. NSDL
Explanation
The correct answer is B, NSDL. The National Securities Depository Limited was set up in 1996, the year the Depositories Act was passed, and was the first depository in India; it holds securities in electronic form so that shares need not change hands as paper certificates, a process called dematerialisation. Option A, the Central Depository Services Limited, was established in 1999 and is the second depository, so it is the closest distractor. Option C, the National Securities Clearing Corporation Limited, is a clearing corporation: it settles trades and guarantees their completion rather than holding securities. Option D, the Clearing Corporation of India Limited, clears and settles transactions in government securities, money market instruments and foreign exchange. An investor reaches a depository through a depository participant, usually a bank or a broker.
Frequently Asked Questions
What is the difference between the primary and the secondary market?
In the primary market a security is issued for the first time and the money raised goes to the company, as in an IPO. In the secondary market, that is the stock exchange, investors trade securities already issued among themselves, and the company receives nothing; the secondary market supplies the liquidity that makes a primary issue attractive.
Why was SEBI given statutory powers in 1992?
The securities scam of that year showed that an administrative body without legal teeth could not police brokers, banks and issuers. The SEBI Act, 1992 gave the Board power to make regulations, register and inspect intermediaries, investigate, and impose penalties, turning a supervisory office into a regulator with enforceable orders.
What is dematerialisation?
Dematerialisation is the conversion of physical share certificates into electronic records held in a demat account with a depository. It was made possible by the Depositories Act, 1996, removed the risks of forged, torn or lost certificates, and cut settlement time sharply. NSDL and CDSL are the two depositories, reached through a depository participant.
What is the difference between the Sensex and the Nifty?
The Sensex is the benchmark index of the Bombay Stock Exchange, made of thirty companies, with 1978-79 as base year and base value 100. The Nifty 50 is the benchmark of the National Stock Exchange, made of fifty companies, with 1995 as base year and base value 1000. Both are weighted by free-float market capitalisation.
What are ADRs and GDRs?
They are depositary receipts that let an Indian company raise money abroad without listing its shares there directly. An American Depositary Receipt is issued in the United States and a Global Depositary Receipt in other foreign markets, each representing shares held by a depository bank. An Indian Depositary Receipt does the reverse for a foreign company raising funds in India.
