A depository is an organisation that holds your shares and other securities in electronic form. In India, there are two depositories: NSDL (National Securities Depository Limited) and CDSL (Central Depository Services India Limited). A Depository Participant (DP) is an intermediary, typically a broker or bank, that connects you to the depository and provides access to your demat account.
What is a depository?
NSDL and CDSL function as digital warehouses for all of India's shares. When you own shares of a company, there is no physical certificate with your name on it. Instead, an electronic record in either NSDL or CDSL states that you own those shares.
Depositories maintain the master database of share ownership across the country. Every transaction, dividend payment, bonus issue, and stock split is recorded here.
The Registrar and Transfer Agent (RTA) acts as an intermediary between the issuing company and the depositories, passing on corporate action information to ensure all changes are properly reflected in the master database.
This electronic system has eliminated the risks associated with physical certificates, theft, damage, and forgery.
What is a Depository Participant (DP)?
NSDL and CDSL do not deal with individual investors directly. You access the depository system through a Depository Participant (DP), similar to how you access the Reserve Bank of India's banking system through a local bank branch, rather than the RBI itself.
DPs are SEBI-registered entities, usually brokers, banks, or financial institutions, authorised to offer demat services. When you open a demat account with a broker like Zerodha, Zerodha acts as your DP (registered with CDSL) and gives you access to your portion of CDSL's records.
Here is how each component fits together:
- Depository (NSDL or CDSL): Maintains the official electronic records of share ownership for the entire country.
- Depository Participant (DP): Provides access to your demat account and handles account opening, maintenance, and transactions.
- Broker: Routes your buy and sell orders to the stock exchange and handles trade execution.
In many cases, your broker and your DP are the same entity. For example, Zerodha is both a broker and a DP registered with CDSL.
Services offered by a DP
Beyond providing access to your holdings, DPs offer several services:
- Stock transfers: DPs process the transfer of shares between accounts, for example, gifting shares to a family member or moving holdings between your own accounts.
- Pledging and loan services: If you want to pledge shares for margin trading or a loan against securities, your DP coordinates with lenders and marks the shares as pledged in the depository system.
- Corporate actions: Dividends, bonus shares, stock splits, and rights issues are automatically processed and credited to your demat account or linked bank account.
- Regulatory compliance: DPs ensure all transactions comply with SEBI regulations and handle the required regulatory reporting on your behalf.
- Account statements: Your DP provides detailed statements, transaction confirmations, and reports that go beyond what a broker's trading app typically displays.
How share settlement works
When you buy shares, the following process takes place:
- You place a buy order through your broker's platform.
- The broker sends the order to NSE or BSE, where it is matched with a seller.
- The clearing corporation, NSE Clearing Limited (NCL) for NSE trades, or Indian Clearing Corporation Limited (ICCL) for BSE trades, guarantees the trade and confirms it to both parties.
- On settlement day, shares are debited from the seller's demat account and credited to yours.
India follows a T+1 settlement cycle, introduced in January 2023. This means if you buy shares on Monday (T day), they appear in your demat account by Tuesday evening (T+1). Until settlement is complete, your broker's app may show these as "T1 holdings."
What happens if your DP shuts down?
If a DP faces regulatory issues or loses its licence, your shares remain safe. Your ownership is recorded with NSDL or CDSL, not with the DP. SEBI ensures that in such situations, you can transfer your holdings to another DP without any loss.
Things to keep in mind
- Never share your login credentials. Sharing your demat login, trading password, or OTPs, even with family members, can expose you to fraud. Scammers can access your account, transfer your shares, or pledge them without your knowledge.
- Keep your contact details updated. If your DP cannot reach you, you may miss fraud alerts, corporate action notifications, or important account updates. Always keep your mobile number, email address, and mailing address current with your DP.
- Add and update nominations. Without a nominee, your legal heirs may need to obtain succession certificates or go through court procedures to claim your shares, a process that can take months or years. Review your nominations at least once a year and after major life events such as marriage, divorce, or the birth of a child.
- Review your account statements. Monthly statements help you spot unauthorised transactions, track corporate actions, and maintain accurate records for tax purposes.
- Don't neglect old demat accounts. Inactive accounts can get frozen due to KYC lapses. Either reactivate them with fresh KYC or close them properly if they are no longer needed.
