How Indian Capital Markets Work
Indian capital markets function through an interconnected chain of regulators (SEBI, RBI), exchanges (NSE, BSE), depositories (NSDL, CDSL), clearing corporations, and intermediaries (brokers, DPs, custodians), all working together to facilitate issuance, trading, and settlement of securities.
Understanding the plumbing of Indian capital markets helps investors appreciate why trades settle reliably, how prices are discovered, and which institution is responsible when something goes wrong.
REGULATORY LAYER: SEBI (Securities and Exchange Board of India) is the apex regulator for securities markets. Established in 1988 and given statutory powers in 1992, SEBI oversees exchanges, brokers, merchant bankers, registrars, depositories, rating agencies, portfolio managers, and research analysts. The Reserve Bank of India (RBI) regulates the G-Sec market and foreign exchange transactions linked to capital markets.
EXCHANGE LAYER: NSE and BSE are SEBI-recognised stock exchanges. They provide the trading platform (electronic order books), set listing requirements, enforce trading rules, and manage the market surveillance function. NSE dominates equity cash and derivatives volume; BSE has a larger number of listed companies and a strong SME platform.
CLEARING LAYER: After a trade is executed, the clearing corporation steps in as a central counterparty (CCP) — it becomes the buyer to every seller and the seller to every buyer, eliminating bilateral default risk. Clearing corporations calculate net obligations, collect margins, and ensure final settlement.
DEPOSITORY LAYER: NSDL and CDSL hold securities in electronic form and transfer ownership between demat accounts upon settlement instructions from clearing corporations. Each investor accesses the depository through a registered Depository Participant (DP), typically a broker or bank.
INTERMEDIARY LAYER: Stockbrokers (registered with SEBI) provide investors the trading interface — whether online platforms, call-and-trade, or advisory services. They are members of exchanges and carry obligations including margin collection and client fund segregation.
TRADE LIFECYCLE: An investor places an order via a broker's platform → the order reaches the exchange's matching engine → matched against an opposing order → trade confirmation sent back → clearing corporation nets obligations → on T+1, shares and funds exchange hands between demat and bank accounts.
This entire chain, from order placement to settlement, is now largely automated and digital, with SEBI continuously pushing for tighter risk controls, transparency, and investor protection across every layer.
