NSDL & CDSL — Role, Functions & Differences

Topic 28 — India's Two Depositories: Comparison, Market Share, Functions & Governance | SEBI Law Officer

India has two depositories — the National Securities Depository Limited (NSDL) and the Central Depository Services Limited (CDSL). Both are regulated by SEBI under the Depositories Act, 1996. While they provide essentially the same services (electronic holding and transfer of securities), they differ in promoter structure, market share characteristics, listing status, and some operational features. SEBI Law Officer and Judiciary aspirants must understand both depositories — their structure, functions, and the comparison between them.

1. NSDL — National Securities Depository Limited

1.1 Background & Structure

1.2 NSDL — Functions & Services

• Dematerialisation: Converts physical certificates into electronic records in demat accounts maintained with NSDL-registered DPs.
• Rematerialisation: Converts electronic holdings back into physical certificates on investor request.
• Settlement of trades: Interfaces with NSE Clearing Limited (NSCCL) to settle exchange-traded transactions — debiting seller's account and crediting buyer's account.
• Pledge creation: Enables investors to pledge dematerialised securities as collateral for loans.
• Corporate actions: Processes dividends, bonus shares, rights issues, and stock splits — crediting benefits directly to beneficial owners' accounts.
• e-Voting: NSDL provides the e-voting platform (NSDL e-Services) used by listed companies for shareholder voting — mandatory under LODR Regulations.
• PAN verification: NSDL hosts the PAN database on behalf of the Income Tax Department — widely used for KYC.

2. CDSL — Central Depository Services Limited

2.1 Background & Structure

2.2 CDSL — Functions & Services

• Dematerialisation & Rematerialisation: Same core functions as NSDL.
• Settlement: Interfaces with Indian Clearing Corporation Limited (ICCL — BSE's clearing corporation) for settlement of BSE trades.
• CDSL Ventures Limited (CVL): CDSL's wholly-owned subsidiary provides KYC services under SEBI's KYC Registration Agency (KRA) framework.
• e-Voting: CDSL provides the EVOTING platform for listed companies — competes with NSDL's e-voting services.
• Insurance Repository: CDSL's subsidiary (CIRL) operates as an Insurance Repository — holds insurance policies in electronic form.
• Commodity Repository: CDSL Commodity Repository Limited — holds commodity warehouse receipts in demat form.

3. NSDL vs CDSL — Comprehensive Comparison

4. Interoperability between NSDL and CDSL

Securities can be transferred between accounts held with NSDL and CDSL DPs — this is called inter-depository transfer. Key features:

• An investor holding securities in an NSDL demat account can transfer them to a CDSL demat account (or vice versa) using the Delivery Instruction Slip (DIS).
• SEBI has mandated that both depositories maintain interoperability — investors are not locked into one depository.
• Inter-depository transfers facilitate portability — investors can switch DPs across depositories.
• Settlement of exchange trades: buyers on NSE get delivery through NSDL; buyers on BSE through CDSL — but inter-depository settlement is seamless.

5. Governance & Regulation of Depositories

Both NSDL and CDSL are regulated by SEBI under:

• Depositories Act, 1996.
• SEBI (Depositories and Participants) Regulations, 2018.
• SEBI Circulars and Master Circulars on depositories.
• SEBI's Market Infrastructure Institution (MII) governance framework — applying to all stock exchanges, clearing corporations, and depositories.

Under the MII governance framework, depositories must:

• Have a governing board with minimum independent directors.
• Separate their regulatory (oversight of DPs) and commercial (revenue-generating) functions.
• Maintain a Settlement Guarantee Fund.
• Publish annual reports and undergo SEBI inspection annually.

6. Nominee Depository — Concept for Pledging

In the pledge mechanism, the pledgee's account is maintained at a 'nominee depository' — the depository holds the pledged securities on behalf of the pledgee. Key distinction:

• Normal demat account: beneficial owner has full rights to securities.
• Pledged securities account: securities are blocked — the pledgee (lender) has a charge over them. If the pledgor defaults, the pledgee can invoke the pledge and become the beneficial owner.
• Pledge creation and invocation are entirely electronic — no physical movement of certificates.
