-->What Is a Demat Account, and Who Holds It?
Zerodha, Groww, Upstox, whichever you use: your broker opens your account, gives you the app and sends your orders to the exchange. But the shares you own don’t sit with your broker. They are held electronically at a depository, CDSL or NSDL, in an account in your name: your demat account.
A demat (dematerialised) account holds shares in electronic form, the way a bank account holds money. India has two depositories, CDSL and NSDL. They do the same job: which one holds your account depends on your broker, and as an investor you won’t notice a difference.
Your broker is usually also your depository participant, the counter through which that demat account is opened and operated. The account itself, and the record that the shares are yours, lives at the depository.
Your broker is the shop window. The depository is the locker. And the locker is in your name.
What Happens to Your Shares If Your Broker Shuts Down?
Because the shares are recorded at the depository in your name, a broker shutting down doesn’t make them disappear. Fully paid shares in your demat account stay yours, and can be moved to an account with another depository participant.
Two things are different, and worth knowing:
- Shares bought on margin (for example, margin trading facility) are pledged to the broker until you pay in full, so the broker has a claim on them.
- Money sitting in your trading account is held by the broker, not the depository. That’s a separate question from your shares.
How to Check Your Shares: the CAS Statement
You don’t have to take your broker’s app at its word. The depository keeps its own record and tells you about it directly: you get a Consolidated Account Statement (CAS) from CDSL or NSDL, and alerts when shares leave your account. If the app and the depository statement ever disagree, the depository is the record that counts.
Why It’s Built This Way
This is a deliberate piece of system design. The company that takes your orders is kept apart from the company that holds your assets. A broker can have an outage, a bad quarter or close down entirely, and the record of what you own sits somewhere else, untouched.
Engineers will recognise the pattern: keep the system of record separate from the systems that act on it, so a failure in one can’t corrupt the other. Markets learned it the hard way, and it’s just as good a rule for payment platforms and ledgers as it is for shares.
The US does this differently: there, shares are usually held in your broker’s name. See Who Holds Your Shares: India vs the US.
