How SEBI regulates Indian capital markets
The Securities and Exchange Board of India is the statutory regulator for the Indian capital markets, established under the SEBI Act 1992 following the Harshad Mehta securities scam of 1992. SEBI’s mandate is “to protect the interests of investors in securities, to promote the development of, and to regulate the securities market and matters connected therewith”. The organisation operates from its headquarters in Mumbai with regional offices across India, employing approximately 1,000 staff across legal, market-policy, investigation, and enforcement functions. Its budget is funded through fees levied on registered intermediaries (stockbrokers, mutual funds, investment advisers) and on transaction-level levies that flow from the exchanges.
The SEBI regulatory framework covers every participant in the Indian primary and secondary securities markets: issuers (companies raising capital through IPOs, FPOs, rights issues), intermediaries (stockbrokers, depository participants, registrars, merchant bankers, mutual funds, investment advisers, research analysts, portfolio managers), market infrastructure institutions (stock exchanges, clearing corporations, depositories), and investors (retail, institutional, foreign portfolio investors). Each category is governed by a dedicated set of regulations issued by SEBI under the powers conferred by the SEBI Act 1992 and the Securities Contracts (Regulation) Act 1956 .
This article serves as an editorial hub on the SEBI regulatory framework, organised by the structural questions a serious participant in Indian capital markets needs answered: how SEBI is constituted, what regulations cover which market segment, how enforcement works, what reforms have shaped the recent landscape, and how investors can seek redressal. Per-regulation details, per-intermediary requirements, and event-specific reform narratives live on the linked spoke articles.
Legal foundation and organisational architecture
The SEBI Act 1992
The SEBI Act 1992 is the statutory foundation of the regulator. The Act was enacted after the 1992 Harshad Mehta scam exposed the inadequacy of the prior regulatory architecture under the Controller of Capital Issues. The Act confers SEBI with the power to register and regulate intermediaries, prohibit fraudulent and unfair trade practices, regulate insider trading, conduct investigations, levy penalties, and issue regulations under Section 30.
SEBI’s powers were further strengthened by amendments in 2002 (Section 11AA broadening the definition of collective investment schemes), 2014 (Section 12A on insider trading), and subsequent updates. The Securities Laws (Amendment) Act 2014 gave SEBI enhanced search-and-seizure powers and the ability to attach property pending investigation.
The board structure
SEBI is governed by a board consisting of a Chairperson, two members from the central government, one member from the Reserve Bank of India, and five additional members. The Chairperson and full-time members are appointed by the central government and hold office for terms specified at appointment. The board’s composition is designed to balance regulatory independence with executive oversight.
The operational structure under the board is organised by market segment. Major departments include:
- SEBI Investment Management Department handling mutual funds, alternative investment funds, portfolio managers, and venture capital funds.
- Department of Listing and Compliance Functions (handling SEBI (LODR) Regulations 2015 compliance by listed issuers).
- Department of Market Regulation overseeing stock exchanges, clearing corporations, and stockbrokers.
- Investigation Department conducting market-misconduct investigations.
- Enforcement Department handling adjudication and penalty proceedings.
- Office of Investor Assistance and Education running the SEBI SCORES portal and SEBI SMART ODR arbitration framework.

Recent reforms shaping the 2020s landscape
The 2020s have seen the most extensive SEBI reforms since 1992, driven by the post-Karvy push for client-asset segregation, the COVID-era growth of retail derivatives participation, and the SEBI study finding 93 per cent of retail F&O traders lose money over FY22-FY24.
Client-asset protection
- The SEBI margin pledge rules of September 2020 replaced the Power of Attorney regime with depository-level pledge plus TPIN authorisation. The rules followed the Karvy Stock Broking pledge-misuse case of 2019 which exposed how the PoA mechanism could be abused by brokers.
- The DDPI framework introduced in 2022 further narrowed the broker’s authorisation to specifically enumerated purposes.
Margin and risk
- The peak margin penalty regime operative from November 2020 required upfront collection of the highest intraday SPAN-plus-exposure-plus-ELM margin, ending the next-day-funding model.
- Phased rollout to full 100 per cent peak margin from September 2021.
Mutual fund reforms
- The SEBI October 2017 scheme categorisation circular standardised 36 fund categories across AMCs.
- The SEBI multi-cap reclassification circular of September 2020 forced multi-cap funds to allocate 25 per cent each in large, mid and small caps.
- The April 2023 debt mutual fund taxation reform removed indexation benefit on debt MF gains.
- The Franklin Templeton debt-fund winding-up of April 2020 prompted the broader debt-fund liquidity and side-pocketing reforms.
F&O regime tightening
- The SEBI F&O entry barrier rules of October 2024 raised contract sizes, restricted weekly expiries, introduced upfront option premium collection, removed expiry-day calendar spread benefit, added intra-day position-limit monitoring, and added 2 per cent ELM on expiry-day short options.
- The weekly expiry contraction of November 2024 collapsed five weekly expiries per week to two.
- The STT hike on F&O of October 2024 raised options-selling STT from 0.0625 per cent to 0.1 per cent and futures-selling STT from 0.0125 per cent to 0.02 per cent.
- The SEBI true-to-label charges framework of October 2024 ended broker volume rebates on exchange transaction charges.
Settlement cycle compression
- T+1 settlement on Indian equity operative from January 2023, completing the transition from T+2.
- T+0 settlement rollout on a voluntary basis from March 2024 for an initial set of 25 stocks, expanding through 2024-25.
Enforcement and grievance redressal
SEBI enforcement powers
SEBI’s enforcement powers include:
- Issuing show-cause notices to suspected violators of regulations.
- Adjudication proceedings with penalties up to Rs 25 crore or three times the unfair gain, whichever is higher.
- Disgorgement of unlawful gains.
- Debarment from securities markets for specified periods.
- Attachment of property pending investigation, under the Securities Laws (Amendment) Act 2014.
- Prosecution for serious offences carrying criminal liability.
Recent high-profile enforcement actions include the proceedings against Quant Mutual Fund on alleged front-running, the historical Karvy Stock Broking order, and ongoing matters in the FPO and IPO compliance space.
Investor grievance redressal
The SEBI SCORES portal is the public-facing investor complaints management system. Investors can file complaints against any SEBI-registered intermediary or listed entity through SCORES, with the system tracking each complaint through stages from filing to resolution. SEBI publishes quarterly data on complaint volumes and resolution rates by intermediary.
SEBI SMART ODR (Online Dispute Resolution) provides a structured arbitration mechanism for unresolved complaints, replacing the older offline arbitration that ran through stock exchanges. SMART ODR was operationalised from late 2023 and covers stockbroker, mutual fund, and depository participant disputes.
The SEBI Investor Protection Fund provides compensation in specific cases of intermediary default, funded by levies on intermediaries.
Public consultation and reform pathway
Major SEBI regulations follow a documented public-consultation pathway:
- Discussion paper published on sebi.gov.in for public comment, typically open for 30-90 days.
- Industry consultation through advisory committees and stakeholder meetings.
- Board approval by the SEBI board following review of comments.
- Regulation publication in the Official Gazette with an effective date.
- FAQs and clarifications issued through subsequent circulars.
The discussion paper-to-regulation cycle typically runs 6 to 18 months for material reforms. For urgent matters, SEBI can issue interim directives under Section 11(4) of the SEBI Act 1992 with retrospective effect.
SEBI’s relationship with adjacent regulators
The Indian capital markets regulatory architecture also involves:
- Reserve Bank of India (RBI): regulator for banks, payment systems, and foreign exchange. SEBI coordinates with RBI on bank-sponsored mutual fund AMCs, depository participant operations of banks, and foreign portfolio investor flows.
- Insurance Regulatory and Development Authority (IRDAI): regulator for insurance, including ULIPs (mutual fund vs ULIP and ELSS vs ULIP ) and insurance-savings products that compete with mutual funds.
- Pension Fund Regulatory and Development Authority (PFRDA): regulator for the National Pension System (NPS), where mutual fund vs NPS Tier 2 and ELSS vs NPS comparisons surface.
- Income Tax Department (CBDT): administers capital gains tax under Section 111A and Section 112A , and the Annual Information Statement infrastructure.
- Ministry of Corporate Affairs (MCA): company law and corporate governance enforcement under the Companies Act 2013, complementary to SEBI LODR.
The High-Level Coordination Committee on Financial and Capital Markets (chaired by the RBI Governor) and the Financial Stability and Development Council (chaired by the Finance Minister) are the formal inter-regulatory coordination forums.
