6. Depositories – NSDL and CDSL
Your grandfather may have kept share certificates in a steel trunk – fancy paper certificates with the company’s name and his name printed on them. Those days are gone. Today, shares live in electronic form in a depository.
Many Indian families have a story like this. Mohan kaka bought shares in the 1980s. Some certificates were damaged by water, some were lost when the family shifted houses, and one had a signature that did not match. Getting those shares back took his son almost two years of letters, affidavits and visits.
This was common. Paper certificates got lost, stolen, forged or stuck in the post. Selling a share could take weeks.
6.1 What is a depository?
A depository is like a giant digital bank – but for securities instead of money. It holds shares, bonds, mutual fund units and more in electronic form, in the name of each investor.
India has two depositories:
- NSDL – National Securities Depository Limited, started in 1996.
- CDSL – Central Depository Services (India) Limited, started in 1999.
Both are regulated by SEBI. Your demat account is opened with one of them, through your broker (who acts as a Depository Participant, or DP).
| Bank for money | Depository for shares |
|---|---|
| Bank | NSDL / CDSL |
| Branch | Depository Participant (your broker) |
| Savings account | Demat account |
| Passbook | Demat statement / CAS |
6.2 Why this matters to you
- Your shares are held in your name, at the depository – not just in the broker’s books. Even if your broker shuts down, your shares stay in your demat account and can be moved to another broker.
- No paper, no loss. No forgery, no lost certificates.
- Fast transfers. Shares move between accounts electronically.
The process of converting old paper certificates into electronic form is called dematerialisation – that is where the word "demat" comes from.
6.3 How to check your shares are really yours
You do not have to trust only your broker’s app. Every month you get a Consolidated Account Statement (CAS) by email from NSDL or CDSL. It shows all your shares and mutual funds across all demat accounts, linked by your PAN.
You can also log in directly to CDSL’s or NSDL’s investor websites to see your holdings.
Once a month, open your CAS and match it with your broker app. It takes two minutes. If something does not match, ask your broker immediately. This habit protects you from errors and fraud.
I am a CA, so I love statements. But this habit is not for CAs. Apna paisa, apni zimmedari – your money, your responsibility. The CAS is the one document that shows the truth from the depository itself.
Shares are held at NSDL/CDSL in your name. The broker is only a participant. You can transfer them to a new broker.
The CAS comes from NSDL or CDSL and covers all holdings linked to your PAN.
- A depository holds securities in electronic form. India has two: NSDL and CDSL.
- Your broker is a Depository Participant – the branch, not the bank.
- Shares sit in your name at the depository, so they are safe even if your broker fails.
- Check your monthly CAS against your broker app.
- Ek line mein: Aapke shares broker ke paas nahi, depository mein aapke naam pe hain – har mahine CAS zaroor check karo.
