Demat account

A demat account (short for dematerialised account) is an electronic repository that holds an investor’s securities – shares, bonds, mutual fund units, government securities, exchange-traded funds, and sovereign gold bonds – in digital form rather than as physical certificates. In India, demat accounts are maintained by two central depositories, CDSL and NSDL , through a network of registered intermediaries called depository participants (DPs). Introduced following the Depositories Act 1996, the demat system eliminated the risks associated with physical share certificates – theft, forgery, loss in transit, and cumbersome transfer procedures – and became the foundation of modern Indian capital markets.

As of early 2024, the combined demat account tally across CDSL and NSDL exceeded 150 million accounts, making India one of the fastest-growing retail investor markets in the world. The account is the entry point for participation in the stock exchanges (BSE and NSE), the primary market , and a growing range of digital financial products.

History and legislative background

Physical-certificate era and its problems

Before the demat system, Indian equity ownership was evidenced by paper share certificates issued by the company registrar. Transferring shares required physical delivery of certificates, a transfer deed signed by the seller, and re-registration by the company. The process took four to six weeks and was riddled with problems: bad deliveries (certificates with signatures that did not match registrar records), theft, loss in transit, forgery, and lengthy correspondence with companies to rectify defective transfers. Market settlement cycles were correspondingly long, settlement risk was high, and the cost and time burden fell disproportionately on retail investors.

The 1992 securities scam orchestrated by Harshad Mehta exposed further weaknesses: brokers routinely used physical certificates as collateral for bank credit, often forging or duplicating them. The resulting loss of investor confidence prompted regulators and the government to undertake a structural overhaul of market infrastructure.

Depositories Act 1996

The Depositories Act 1996 provided the legal framework for holding securities in dematerialised form. The Act created the concept of a depository – a company that holds securities in electronic form on behalf of investors – and defined the roles of depositories, DPs, and beneficial owners. It also established that a DP is an agent of the depository, and that the beneficial owner’s name in the depository records confers legal ownership equivalent to possession of a physical certificate.

The Securities and Exchange Board of India (SEBI) was empowered to regulate depositories and DPs under the Act. SEBI issued the SEBI (Depositories and Participants) Regulations 1996 (subsequently amended and replaced by the SEBI (Depositories and Participants) Regulations 2018), laying down conditions for registration, operational standards, audit requirements, and grievance redressal.

Launch of NSDL and electronic settlement

The National Securities Depository Limited (NSDL) was incorporated in August 1996 and began operations in November 1996, making it India’s first depository. NSE and BSE initially mandated demat settlement for a rolling list of scrips beginning in 1997. By January 2000, SEBI made it compulsory for all scrips traded on stock exchanges to be settled in demat form. Physical shares could still exist, but they could not be transacted on the exchanges.

The Central Depository Services (India) Limited (CDSL) commenced operations in 1999, providing competition and expanding DP coverage, particularly through partnerships with bank-linked brokers.

Milestones in dematerialisation

Components of the demat ecosystem

Depository

A depository is the central record-keeping institution. It holds securities in dematerialised form and maintains the master register of ownership. In India, CDSL and NSDL are the only two SEBI-registered depositories. They do not interact directly with end investors; all investor-facing operations are conducted through DPs.

Depository participant (DP)

A depository participant is an intermediary registered with one or both depositories and authorised by SEBI to offer demat services to investors. DPs may be stockbrokers , banks, non-banking financial companies (NBFCs), or other financial institutions. When an investor opens a demat account, they open it with a DP, not directly with the depository. The DP maintains the investor’s account records and transmits instructions to the depository’s central system.

ISIN

The International Securities Identification Number (ISIN) is a 12-character alphanumeric code that uniquely identifies a specific security. The first two characters are the country code (IN for India), the next nine characters identify the issuer and instrument, and the final character is a check digit. All transactions in a demat account reference the ISIN of the security being transacted.

Beneficial owner (BO) account

The demat account is formally called a beneficial owner account. The term reflects the legal structure: the depository is the registered owner of securities in the sense of the company’s register, while the investor is the beneficial owner – the person entitled to the economic benefits (dividends, voting rights, buyback entitlements). The BO account number, sometimes called the client ID, is a 16-digit number (8 digits for the DP ID and 8 digits for the client ID) under CDSL, or a structured numeric code under NSDL.

Registrar and transfer agent (RTA)

The registrar and transfer agent (RTA) is appointed by each listed company to maintain its shareholder records. The RTA liaises with the depositories when new shares are allotted (as in IPOs or bonus issues) or when corporate actions such as dividends, rights, and mergers are processed. Investors do not interact with the RTA directly in most routine operations; the depository and DP handle the interface.

The two Indian depositories

NSDL

National Securities Depository Limited was promoted by the National Stock Exchange (NSE), the Industrial Development Bank of India (IDBI), and the Unit Trust of India (UTI). It began operations in November 1996. NSDL historically commanded a larger share of the institutional and high-net-worth segment. Its technological infrastructure, built with assistance from the Depository Trust Company (DTC) of the United States, was designed to handle the settlement requirements of NSE’s high-volume electronic trading system.

Key figures (as of 2024): NSDL had approximately 40 million active demat accounts, holding assets under custody exceeding Rs 300 lakh crore. It connected to over 275 registered DPs and over 56,000 DP service centres across India.

CDSL

Central Depository Services (India) Limited was promoted by the Bombay Stock Exchange (BSE) along with leading banks including State Bank of India, Bank of India, Bank of Baroda, and HDFC Bank. It began operations in 1999. CDSL initially focused on retail investor expansion through bank-linked DPs. Over time, it overtook NSDL in total account count, driven partly by its association with Zerodha (which uses CDSL) and Groww, both of which saw explosive retail growth post-2020.

CDSL became a publicly listed company in 2017, the first and so far only depository in the world to list on a stock exchange. Its shares trade on BSE and NSE under the ticker CDSL. As of early 2024, CDSL had approximately 110 million active demat accounts, making it the larger of the two depositories by account count.

Comparison

Functionally, a securities investor can hold accounts with both depositories (through different DPs), though most investors maintain only one. Securities credited after an NSE trade typically settle into an NSDL or CDSL account depending on the DP’s affiliation; both depositories settle trades across both exchanges.

Eligibility and account types

Resident individuals

Any resident Indian individual who is 18 years of age or older can open a demat account. Minors can hold demat accounts operated by a guardian; the account converts to a regular account upon the minor attaining majority.

Non-resident Indians (NRIs)

NRIs can hold demat accounts in India, but the type of account depends on the nature of investments:

• NRE (Non-Resident External) demat account: Linked to an NRE bank account. Holds securities purchased on a repatriation basis – proceeds of sale can be remitted abroad. Used for Portfolio Investment Scheme (PIS) investments, where the RBI-authorised bank monitors the NRI’s stock market purchases under the Foreign Exchange Management Act (FEMA).
• NRO (Non-Resident Ordinary) demat account: Linked to an NRO bank account. Holds securities purchased on a non-repatriation basis. FEMA restrictions apply to remitting sale proceeds abroad beyond prescribed limits.
• PIS route: NRIs wishing to invest in listed Indian equities on the secondary market must obtain PIS permission from an RBI-authorised bank. The bank monitors that the NRI does not breach the permissible investment limits per scrip (5% for general NRI holding, with a portfolio cap). Mutual fund investments by NRIs do not require PIS permission.

Hindu Undivided Family (HUF)

A HUF can open a demat account in the name of the Karta (the senior-most male member of the family). The PAN card of the HUF is used for KYC. The account can hold securities in the HUF’s name and receive dividends in the HUF’s bank account.

Corporate entities

Companies, limited liability partnerships (LLPs), and other bodies corporate can open demat accounts. The account is in the corporate entity’s name, with authorised signatories designated for instruction purposes. The KYC process requires the entity’s PAN, certificate of incorporation, board resolution authorising the account opening and the authorised signatories, and identity/address proof of the signatories.

Trusts and societies

Registered trusts and societies can hold demat accounts for their investment portfolios, subject to the trust deed or governing document permitting securities investments. The trust’s registration documents, PAN, and trustee details are required for KYC.

Joint accounts

Demat accounts can be held jointly by up to three individuals. The first holder is the primary account holder, and all tax-related matters (dividend income, capital gains) flow through the first holder’s PAN. In the event of the first holder’s death, the account may be transmitted to the surviving joint holders or to the nominee.

How to open a demat account

The account-opening process was substantially digitised following SEBI’s eKYC and Aadhaar-based verification frameworks. As of 2022, most brokers complete the process entirely online within 15 to 30 minutes for a resident individual.

Step 1: Choose a depository participant

The investor selects a DP, which may be a broker (Zerodha, Groww, Upstox, Angel One, etc.), a bank (ICICI Bank, HDFC Bank, Kotak Bank, Axis Bank, etc.), or another registered entity. The choice of DP determines the depository (CDSL or NSDL), the fee structure, and the ancillary services (trading platform, research, margin facilities). A comparison of major brokers is covered in the companion article Indian retail brokers comparison .

Step 2: Complete KYC

KYC (Know Your Customer) requirements under SEBI and the Prevention of Money Laundering Act (PMLA) require:

• PAN card: Mandatory for all demat account holders.
• Aadhaar card: Used for address proof and, where the investor consents, for Aadhaar-based e-verification (eKYC).
• Bank account proof: A cancelled cheque or bank statement, used to link the savings or current account for fund transfers related to trading.
• Photograph: A recent passport-size photograph.
• Income proof (for F&O and currency derivatives segments): Pay slips, ITR, or bank statements showing financial capacity.

Step 3: eKYC and in-person verification

Since 2020, SEBI has permitted fully digital KYC using Aadhaar-based OTP authentication (for accounts linked to Aadhaar-registered mobile numbers) and video-based in-person verification (IPV). The investor:

1. Enters personal details, PAN, and Aadhaar number on the DP’s platform.
2. Completes OTP-based Aadhaar authentication through the UIDAI portal.
3. Completes a brief video IPV session in which the applicant holds their PAN card to the camera and answers verification questions posed by a DP representative (or automated system).

Alternatively, for bank-linked DPs, Aadhaar-based net banking verification can serve as IPV.

Step 4: Segment activation

The default demat account is activated for the equity cash segment. Additional segments – futures and options (F&O), currency derivatives, commodity derivatives, and debt securities – require separate activation, often with additional income proof declarations.

Step 5: Receive BO account details

Once the account is opened, the investor receives:

• The BO account number (client ID) and DP ID from CDSL or NSDL.
• Login credentials for the DP’s trading and demat platform.
• A welcome kit (physical or digital) containing account terms, tariff schedule, and rights and obligations document.

Role of the depository participant

The DP acts as the interface between the investor and the central depository. Its core functions include:

• Account maintenance: Maintaining the investor’s demat account, processing credits (purchases, IPO allotments, bonus shares, rights) and debits (sales, pledges).
• Instruction processing: Executing delivery instructions submitted by the investor to transfer securities to another demat account.
• Corporate action processing: Crediting bonus shares, rights entitlements, stock dividends, and mutual fund dividend re-investment units to the investor’s account following directions from the depository.
• Pledge and hypothecation: Facilitating the pledge of securities as collateral for margin trading or loans against securities (LAS).
• Transmission: Processing the transfer of securities following the death of a holder, based on the nominee or succession documents.
• Grievance redressal: Acting as the first point of contact for investor complaints; bound by SEBI’s SCORES (Securities and Exchange Board of India Complaints Redress System) framework.

The DP must be registered separately with SEBI as a stock broker (if offering trading) and with the relevant exchanges. SEBI inspection of DPs is conducted periodically; DPs found to be deficient can be fined, suspended, or deregistered.

Fee structure

Demat account fees are not standardised; DPs set their own tariff schedules within SEBI-prescribed outer limits. The principal fee heads are:

Account-opening charge

Many discount brokers (Zerodha, Groww, Upstox, Dhan) waive the account-opening charge entirely for online applications or charge a nominal one-time fee of Rs 200 to Rs 300. Full-service bank DPs (ICICI Bank, HDFC Bank, Kotak) may charge Rs 500 to Rs 750. The fee covers the cost of KYC processing and initial account setup.

Annual maintenance charge (AMC)

The AMC is the annual subscription fee for maintaining the demat account. Typical ranges:

• Discount brokers: Rs 0 to Rs 400 per year (some brokers waive AMC for the first year).
• Bank DPs: Rs 300 to Rs 900 per year.
• SEBI has proposed a cap on AMC to make demat accounts more accessible to small investors; as of 2024, no mandatory cap was in force, but competitive pressure had already driven AMC down among discount brokers.

SEBI mandates that basic services demat accounts (BSDAs) – accounts with holdings below Rs 2 lakh in value – shall be exempt from AMC. The BSDA facility, introduced in 2012, is designed for small investors and requires the DP to waive AMC when the holding value remains below the prescribed threshold.

Transaction charges

Transaction charges apply to each debit instruction from the demat account (i.e., each sale or delivery transaction). Credits (purchases, allotments) are typically free. Debit charges range from Rs 10 to Rs 25 per instruction among discount brokers. Some DPs charge a flat rate; others charge a percentage of the transaction value, subject to a minimum and maximum.

Custody charges (fees for holding securities, common in some international markets) were abolished by SEBI and the depositories for retail demat accounts.

Off-market transfer charges

Transferring securities between demat accounts outside the exchange settlement mechanism (for example, gifting shares) attracts an off-market transfer charge, typically Rs 25 to Rs 100 per ISIN per transaction.

Pledge and unpledge charges

Creating or releasing a pledge on securities (used for margin trading or loans against shares) attracts fees, typically Rs 20 to Rs 50 per pledge instruction.

Consolidated account statement (CAS)

CDSL and NSDL jointly provide the Consolidated Account Statement, which covers all demat holdings and mutual fund folios linked to a PAN. The CAS is sent by email and post monthly if there have been transactions, or at least bi-annually. The CAS is free of charge.

Services available through a demat account

Viewing holdings

The investor can view their current holdings – equity shares, bonds, ETFs, sovereign gold bonds, and mutual fund units – through the DP’s app or web platform, or directly through CDSL’s myEASI portal or NSDL’s Speed-e and IDeAS portals.

Transaction history

All credits and debits are recorded with date, ISIN, quantity, and nature of the transaction (purchase, sale, IPO allotment, bonus, pledge, off-market transfer). The transaction history is available through the DP’s platform and through the CAS.

Pledge for margin

Securities held in demat can be pledged as margin for trading in the equity derivatives, currency derivatives, or commodity derivatives segments. The SEBI margin pledge mechanism , introduced in September 2020, requires the investor’s consent (via a separate OTP or two-factor authentication) to create a pledge; the broker cannot unilaterally move the securities. Pledged securities remain in the investor’s account (marked as pledged) and continue to attract dividends and corporate action entitlements for the investor.

Loans against securities

Banks and NBFCs offer loans against securities (LAS) in which the investor pledges demat-held shares or bonds as collateral. The loan amount is a percentage (typically 50% to 80%) of the market value of the pledged securities. LAS is tax-neutral (the pledge does not constitute a transfer for capital gains purposes).

Transmission

Upon the death of the account holder, securities can be transmitted to:

• A jointly held co-applicant (if the account is jointly held).
• The registered nominee.
• The legal heir (if no nominee was registered), through the succession process requiring a legal heir certificate or probated will.

The transmission process has been simplified by SEBI; for holdings below Rs 15 lakh in value per issuer, an indemnity bond suffices in lieu of succession certificate.

Nomination

Every demat account holder is encouraged to register a nominee. Following SEBI’s 2021 directive, all existing account holders were required to either register a nominee or opt out of nomination by a stated deadline. Non-compliance could result in account freezing. Nomination can be updated at any time online through the DP.

Corporate actions

Dividends on equity shares held in demat are credited directly to the investor’s linked bank account via NACH (National Automated Clearing House). Bonus shares and rights entitlements are credited automatically to the demat account. Stock splits (and reverse splits) are processed at the ISIN level; the quantity adjusts automatically in the investor’s account.

Recent reforms and milestones

Pledge mechanism reform (September 2020)

Before September 2020, brokers routinely required investors to sign a power of attorney (PoA) in favour of the broker, which gave the broker authority to move securities out of the investor’s demat account – for purposes of collateral, pay-in obligations, or otherwise – without requiring the investor’s transaction-by-transaction consent. This practice was exploited in a number of broker failures (Karvy Stock Broking, 2019, being the most prominent), where client securities were pledged or transferred without authorisation.

SEBI’s circular of August 2020 (effective September 2020) introduced the margin pledge mechanism, under which:

• Securities remain in the investor’s demat account, pledged in favour of the broker.
• Each pledge or unpledge instruction requires the investor’s OTP authentication.
• The broker cannot transfer securities out of the investor’s account without the investor’s explicit, transaction-level consent.
• The PoA route was substantially curtailed; the only PoA permitted was a limited one for pay-in of sold securities (debit instructions during settlement).

DDPI (Demat Debit and Pledge Instruction) – 2022

The Demat Debit and Pledge Instruction (DDPI) was introduced by SEBI in 2022 as a replacement for the PoA for the limited purpose of authorising the broker to debit the investor’s demat account for:

• Pay-in obligations arising from sale transactions on the exchanges.
• Creating pledges for margin.

The DDPI is a pre-signed, standing instruction that eliminates the need for an investor to manually approve every sale debit. It is narrower in scope than the old PoA: it cannot be used by the broker to transfer securities for reasons other than settlement or pledge creation. Signing the DDPI is optional; investors can alternatively approve each debit transaction individually via the broker’s app.

T+1 settlement (2023)

India transitioned to a T+1 rolling settlement cycle for all exchange-listed scrips by the end of January 2023, making it one of the first major markets globally to implement T+1 as the default. Under T+1:

• Securities sold on trade day (T) are debited from the seller’s demat account and credited to the buyer’s demat account on T+1 (the following business day).
• Funds flow reciprocally: the buyer’s account is debited and the seller’s account is credited on T+1.

The transition reduced settlement risk, freed up capital (funds and securities are blocked for a shorter period), and reduced the opportunity for failed trades arising from delays.

T+0 pilot (2024)

In March 2024, SEBI launched an optional T+0 (same-day) settlement pilot for a select set of 25 frequently traded scrips on BSE and NSE. Under T+0, investors who opt in receive funds and securities on the same trading day, reducing settlement risk further. The pilot is voluntary; investors can choose T+0 or T+1 for each trade. The programme is under review for broader rollout.

SEBI SCORES and ODR

SEBI’s online grievance platform SCORES (sebi.gov.in/sebiweb/other/OtherActivity.do?doRecognisedFpo=yes) allows investors to lodge complaints against DPs, brokers, and RTAs. SEBI has also introduced an Online Dispute Resolution (ODR) portal (smartodr.in) as a pre-litigation arbitration mechanism for securities market disputes.

International equivalents

The concept of centralised dematerialised securities holding is not unique to India; most developed and several emerging markets operate similar systems:

The Indian model most closely resembles the US DTC model in its two-tier structure (central depository + intermediary DPs) and its separation of the settlement function (handled by the clearing corporations NSCCL and ICCL) from the custody function (handled by NSDL and CDSL).

Common operational issues

Mismatch in name across documents

A common source of account-opening rejection is a mismatch between the name on the PAN card and the name on the Aadhaar card (for example, initials expanded in one document, or a father’s name included in one but not the other). The investor must resolve the discrepancy at the relevant authority (UIDAI for Aadhaar, the Income Tax Department for PAN) before the account can be opened.

Demat account freeze

SEBI has mandated that demat accounts be frozen if:

• The investor fails to update their nomination status by the prescribed deadline.
• The investor has not completed the KYC re-verification process under SEBI’s periodic KYC norms.
• Suspicious transactions are flagged under PMLA.

A frozen demat account can receive credits (securities can be deposited into it) but debits (selling securities) are blocked until the freeze is lifted.

DP transfer on broker failure

If a broker/DP becomes insolvent or is deregistered, the investor’s securities remain safe in the demat account maintained by the depository. The investor can transfer the account to another DP by submitting a demat account transfer request (using form TRF). The account transfer is free under SEBI rules (DPs cannot charge for inter-depository or intra-depository transfers initiated by the investor).

Corporate action credits not received

If a bonus or rights credit does not appear in the demat account within the expected timeline (usually five to seven business days after the record date), the investor should first check whether the ISIN is visible in the account with a quantity of zero (which may indicate a processing delay) and then contact the DP or the company’s RTA.

Dividend not credited

Dividends are paid directly to the investor’s bank account linked to the demat account. Common causes of dividend non-receipt include an incorrect or outdated bank account linked to the demat, NACH mandate failure, or a name mismatch between the demat account and the bank account. The investor should verify the bank mandate through the DP’s portal and contact the RTA if the issue persists.

Securities appearing in demat but not tradeable

Securities suspended from trading, companies undergoing delisting proceedings, or scrips placed on the Exchange’s trade-for-trade or surveillance framework may appear in the demat account as holdings but cannot be traded freely. The quantity is still recorded, and corporate actions still apply.
