Regulators, Intermediaries, RBI and SEBI (ISC Class 12)

Updated 18 October 2026 · Fact-checked

A regulator is an independent authority created by law to frame rules, license, supervise and penalise businesses in a sector, protecting customers and investors. An intermediary stands between two parties and facilitates transactions, and must follow the regulator's rules. The RBI regulates banks and NBFCs; SEBI regulates stock exchanges, brokers, merchant bankers, depositories, mutual funds and credit rating agencies.

Notice the layers: regulators (RBI, SEBI) make rules for intermediaries, which deal with and protect customers and investors.

Understand Regulators, Intermediaries, RBI and SEBI

1. Regulator. An independent authority created by law to frame rules, grant licences or registration, supervise and inspect the businesses in a sector, and protect the interests of customers, investors and the public. It can impose penalties for violations.

2. Intermediary. An institution or person that stands between two parties and facilitates transactions or services: a bank between depositors and borrowers, a stock broker between investors and the stock exchange, an insurance agent between insurer and policyholder. Intermediaries must be registered with and follow the rules of the relevant regulator.

3. Why regulation is needed. To protect customers and investors; ensure fair practices and stability; maintain standards of quality and safety; and build public trust. Keep the pair straight: RBI is a regulator, the State Bank of India is an intermediary that it regulates.

4. RBI (Reserve Bank of India). India's central bank and the regulator of the banking system.

  • Over Indian and foreign banks operating in India: licensing (no bank can start or open branches without RBI permission); prudential rules such as the cash reserve ratio, statutory liquidity ratio, capital adequacy and limits on lending; inspection and supervision, with power to remove management or impose penalties; protection of depositors and stability of the system; customer-service rules and an ombudsman scheme for complaints.
  • Over NBFCs (non-banking financial companies such as loan, leasing and housing finance companies): registration; rules on deposits, capital and lending; regular returns and inspection; action against defaulters.

5. SEBI (Securities and Exchange Board of India). Regulates the securities (capital) market to protect investors and promote its fair, orderly development.

  • Stock exchanges: recognises them, approves their rules, monitors trading to prevent manipulation.
  • Stock brokers: registration, code of conduct, capital rules, protection of clients' funds and securities.
  • Merchant bankers: registration and rules for managing public issues of shares and debentures.
  • Depositories and their participants: registration and supervision.
  • Mutual funds: registration, rules on investment, disclosure and charges.
  • Credit rating agencies: registration and rules to ensure objective ratings.
  • Also bans insider trading and fraud, requires disclosure by companies, and handles investor complaints.

6. Quick map. RBI: banks, NBFCs. SEBI: the securities market and its intermediaries.
