What is the function of CDSL and NSDL in India?
In India, securities such as stocks, bonds, and mutual fund units are no longer held in physical form. Instead, they are stored electronically in a Demat account, thanks to the country’s two SEBI-regulated depositories: CDSL (Central Depository Services India Ltd) and NSDL (National Securities Depository Ltd).
What do CDSL and NSDL do?
These depositories perform the following key roles:
- Secure Holding: They hold your securities in electronic form, replacing traditional paper certificates.
- Settlement of Trades: They facilitate the electronic settlement of trades executed on stock exchanges.
- Demat Account Support: They work through Depository Participants (DPs)—like FYERS—to enable you to open and manage Demat accounts.
- Corporate Action Processing: They credit bonuses, dividends, rights issues, and splits directly to your Demat account.
- Record-Keeping: They maintain detailed records of your shareholding, including ISIN, quantity, and transaction history.
Why does India have two depositories?
- NSDL was the first depository, launched in 1996 to dematerialize securities.
- CDSL followed in 1999 and is promoted by BSE (Bombay Stock Exchange).
- Both function similarly and are governed by SEBI regulations, but your account is usually linked to either CDSL or NSDL based on your broker.
IPO example
When a company launches an IPO of ₹10 crore or more, SEBI mandates that shares be allotted only in dematerialised (Demat) form. Once the shares are allotted:
- If your Demat is under CDSL, the shares are credited via CDSL.
- If under NSDL, they’re credited via NSDL.
What If...
| Scenario | Explanation |
|---|
| I don’t know which depository my account is linked to | You can check your Demat account number; CDSL accounts typically start with '120' and NSDL with 'IN'. |
| My shares don’t show up after allotment | Check if the right DP ID and client ID were provided. Contact support if needed. |
| I want to change from CDSL to NSDL or vice versa | You need to transfer holdings and open a new Demat with the desired depository via a registered DP. |
Both CDSL and NSDL are secure, efficient, and reliable. You don’t need to maintain separate accounts with both unless you have specific investment preferences or requirements.
