What is a Demat Account?
A demat account (short for dematerialised account) holds your shares, bonds, ETFs, mutual fund units, and sovereign gold bonds in electronic form. Just like a bank account holds your money, a demat account holds your financial securities. Without one, you cannot buy or sell shares on NSE or BSE.
Before 1996, shares were held as physical certificates — paper documents that could be lost, forged, or damaged. SEBI mandated dematerialisation, and today 100% of trading is electronic.
CDSL vs NSDL — Two Depositories
India has two central depositories that actually hold your securities electronically:
- CDSL (Central Depository Services Limited): Promoted by BSE. Used by Zerodha, Groww, Angel One, and most discount brokers. Listed company — ticker CDSL on NSE.
- NSDL (National Securities Depository Limited): Promoted by NSE. Used by ICICI Direct, HDFC Securities, Kotak Securities, and most bank-backed brokers.
Your broker decides which depository you are on. For most retail investors, the choice is irrelevant — both depositories are equally safe and regulated by SEBI.
What Can a Demat Account Hold?
- Equity shares (NSE/BSE listed companies)
- Preference shares
- Bonds and debentures
- Exchange-Traded Funds (ETFs)
- Sovereign Gold Bonds (SGBs)
- Government securities (G-Secs)
- Mutual fund units (only if held in demat form — optional)
Demat Account Charges
Understanding charges prevents bill shock:
- Account opening fee: ₹0–₹500. Most discount brokers (Zerodha, Groww) offer free opening.
- Annual Maintenance Charge (AMC): ₹0–₹750/year. Many brokers charge ₹300–₹400. Zerodha charges ₹300 after first year.
- DP (Depository Participant) transaction charges: ₹13.5 + GST per debit transaction (sell side). This is charged by CDSL/NSDL regardless of broker.
- Custodian fees: If you hold SGB, G-Secs — typically ₹0 to minimal.
How to Open a Demat Account
Opening takes 10–30 minutes online (Aadhaar-linked, paperless). You need:
- PAN card (mandatory)
- Aadhaar card (for e-KYC via OTP)
- Bank account details (cancelled cheque or bank statement)
- Signature (uploaded photo)
- Webcam or front camera for in-person verification (IPV)
Popular choices: Zerodha (large discount broker, ₹20/trade), Groww (zero AMC first year, beginner-friendly), Angel One (₹20/order), ICICI Direct (full-service, higher cost but bank integration).
One Demat, Multiple Trading Accounts?
Yes. You can have demat accounts with multiple depositories (up to one CDSL + one NSDL) and link different trading accounts to each. Many investors hold a primary demat at one broker and a secondary at another for IPO allotment diversification (applying with different ASBA bank accounts).
