Indian Capital Markets: BSE, NSE, SEBI Act & Depositories

Capital markets in India mobilize household savings and allocate long-term debt and equity capital to corporations and public authorities. The secondary market began with the Bombay Stock Exchange, founded in 1875 as The Native Share and Stock Brokers' Association, recognized as the oldest stock exchange in Asia. Modernization accelerated following the recommendations of the M.J. Pherwani Committee, leading to the incorporation of the National Stock Exchange of India in 1992, which commenced operations in 1994 using fully automated, electronic screen-based order matching. Price movements across domestic equity markets are monitored through premier benchmark indices: the S&P BSE Sensex, tracking thirty financially sound large-cap companies from a base year of 1978–79, and the Nifty 50, reflecting fifty diversified stocks across major economic sectors from a base year of 1995.

Regulatory governance over securities markets is exercised by the Securities and Exchange Board of India, initially constituted by executive resolution in 1988 and granted statutory authority through the Securities and Exchange Board of India Act, 1992. Section 11 of the Act mandates the board to protect investor interests, regulate stock exchanges and financial intermediaries, and promote market transparency. The regulatory framework enforces strict compliance through the Prohibition of Insider Trading Regulations and measures curbing fraudulent and unfair trade practices. Investor grievances are processed through the centralized online platform SCORES, while appeals against orders issued by the regulatory board are adjudicated by the Securities Appellate Tribunal, established under Section 15K of the Act.

Infrastructure reforms dismantled physical share certificates through the Depositories Act, 1996, creating an electronic dematerialized framework administered by two licensed depositories: National Securities Depository Limited and Central Depository Services (India) Limited. Converting securities into fungible electronic entries eliminated risks associated with stolen certificates, forged transfers, and bad deliveries. Trading efficiency advanced through compressed settlement cycles, moving progressively from historical account periods to rolling settlement cycles, with Indian equity markets completing the nationwide transition to a full T+1 settlement cycle in January 2023. In UPSC CSE and SSC CGL examinations, key evaluative themes encompass SEBI's quasi-judicial and enforcement mandates, depository functions under the 1996 statute, index weighting methodologies, Pherwani Committee contributions, and the operational structure of capital market settlements.

Educator's Insight
Capital markets channel long-term savings into business investments through stocks and bonds. India operates two major exchanges: the Bombay Stock Exchange, established in 1875 as Asia's oldest bourse, and the National Stock Exchange, incorporated in 1992 following the Pherwani Committee recommendations. The market watchdog is the Securities and Exchange Board of India, which received statutory authority through the SEBI Act of 1992. The Depositories Act of 1996 enabled paperless trading by establishing digital depositories, NSDL and CDSL.
For UPSC, SSC, and banking exams, questions focus on market indices, settlement rules, and regulatory structures. Keep in mind that the BSE Sensex tracks thirty blue-chip stocks, whereas the NSE Nifty tracks fifty stocks. A frequent test trap concerns trade settlements: India completed its migration to the T+1 settlement cycle in 2023, speeding up liquidity and reducing counterparty risk. When preparing regulatory topics, remember that appeals against SEBI orders lie before the Securities Appellate Tribunal.
