Historical Background
Before NSDL’s inception, the Indian capital market faced issues like bad deliveries and delayed transfers due to the reliance on paper-based settlements. The enactment of the Depositories Act in August 1996 paved the way for NSDL’s establishment, aiming to address these inefficiencies by introducing a dematerialized system for securities transactions.
Services and Operations
NSDL offers a range of services to various market participants, including investors, stock brokers, custodians, and issuer companies, through its network of Depository Participants (DPs). Key services include:
Dematerialization (Demat): Conversion of physical certificates into electronic form.
Rematerialization (Remat): Reconversion of electronic securities back into physical certificates.
Settlement of Trades: Facilitating the transfer of securities ownership through electronic means.
Pledging and Unpledging of Securities: Enabling investors to pledge securities for loans and release them upon repayment.
Corporate Actions Processing: Handling actions like dividends, bonuses, and rights issues electronically.
Structure and Subsidiaries
NSDL operates alongside Central Depository Services Limited (CDSL), another central securities depository in India. While both serve similar functions, NSDL is notable for its pioneering role and substantial market presence.
Security Measures
To ensure the safety and integrity of the securities held, NSDL has implemented robust security protocols, including
Data Encryption: Protecting data during transmission to prevent unauthorized access.
Firewalls and Intrusion Detection Systems: Monitoring and safeguarding the network from potential threats.
Regular Audits and Compliance Checks: Ensuring adherence to regulatory standards and identifying vulnerabilities.
