Chapter 6: Depository — Complete Study Notes & Exam Guide
6.1 Understanding Depositories and Their Analogy to Banks
What is a Depository?
A depository is a financial institution that holds securities such as shares, debentures, bonds, Government securities, and mutual fund units in electronic form on behalf of investors. It functions similarly to a bank, but instead of holding and transferring cash, it holds and transfers financial securities electronically.
Analogy Between a Bank and a Depository
The operational mechanism of a depository directly mirrors that of a commercial bank.
| Feature / Function | Commercial Bank | Depository |
|---|---|---|
| Account Holdings | Holds financial funds in a bank account. | Holds securities in an electronic demat account. |
| Transfer Mechanism | Transfers funds between accounts based on the instruction of the account holder. | Transfers securities between accounts based on the instruction of the account holder. |
| Handling Method | Facilitates monetary transfers without physical cash handling. | Facilitates ownership transfers of securities without physical handling of share certificates. |
| Safekeeping Objective | Ensures the safekeeping of deposited money. | Ensures the safekeeping of deposited shares and securities. |
6.2 Depositories, Participants, and Operations in India
6.2.1 Depositories Operating in India
In India, dematerialisation services and electronic security custody are provided by two primary depositories:
- National Securities Depository Limited (NSDL).
- Central Depository Services (India) Limited (CDSL).
6.2.2 Benefits of Participating in a Depository System
Holding securities in electronic demat form through a depository offers numerous operational and financial advantages over physical share handling:
- Immediate Transfer of Securities: Securities are transferred instantly upon transaction settlement without postal delays.
- Exemption from Stamp Duty: No stamp duty is levied on the transfer of dematerialised securities.
- Elimination of Physical Risks: Risks inherent to physical share certificates—such as bad delivery, fake or forged securities, theft, mutilation, or loss in transit—are completely eliminated.
- Cost & Paperwork Reduction: Paperwork involved in processing transfers is drastically reduced, lowering overall transaction costs.
- Nomination Facility: Investors enjoy streamlined nomination features for their security holdings.
- Single Window Address Update: A change of address registered with the Depository Participant automatically updates records across all companies where the investor holds shares, eliminating separate correspondence.
- Direct Transmission: Transmission of securities upon death or legal succession is handled directly by the DP without requiring individual company filings.
- Consolidation of Folios: Multiple accounts and folios can be conveniently consolidated into a single electronic holding.
- Multi-Asset Consolidated Holding: Equities, debt instruments, and Government securities can all be held together within one single demat account.
- Automatic Credit of Corporate Actions: Corporate benefits such as bonus shares, stock splits, consolidations, or mergers are automatically credited directly to the investor's demat account.
6.2.3 Depository Participant (DP) & Account Rules
Who is a Depository Participant?
A Depository Participant (DP) acts as an authorized agent of the depository, serving as the bridge between the depository and individual investors. DPs are appointed by the depository subject to mandatory approval from the Securities and Exchange Board of India (SEBI).
According to SEBI regulations, three categories of entities are eligible to become DPs:
- Banks.
- Financial Institutions.
- SEBI-registered Trading Members (Stockbrokers).
Most brokers and financial institutions offer DP services alongside trading accounts to provide complete single-window financial services.
Minimum Balance Requirement
- Depositories do not prescribe any minimum balance of securities.
- Investors are legally permitted to maintain a zero balance in their demat account without penalty.
6.2.4 International Securities Identification Number (ISIN)
An ISIN (International Securities Identification Number) is a standardized, unique global identification code assigned to a specific security. Every listed stock, bond, or instrument has a unique ISIN to ensure precise tracking during electronic transfers.
6.2.5 Role and Core Functions of a Custodian
A Custodian is an organization that registers and safeguards the financial securities of its institutional or retail clients. Beyond basic physical and electronic custody, a custodian manages corporate actions and administrative tracking on behalf of investors.
Primary Functions of a Custodian:
- Account Maintenance: Maintaining detailed records of the client’s securities accounts.
- Benefit Collection: Collecting dividends, interest, rights, and corporate benefits accruing to the client's holdings.
- Corporate Action Information: Keeping clients continuously informed about issuer actions, voting rights, and corporate announcements affecting their holdings.
6.2.6 Dematerialisation (Demat) Process & DRF
What is Dematerialisation?
Dematerialisation is the conversion process through which physical paper share certificates of an investor are destroyed and converted into an equivalent number of electronic securities credited to their depository account.
| STEP | PROCESS | KEY DETAIL |
|---|---|---|
| 1 | 📄 Submit DRF + Certificates | Investor submits the Dematerialisation Request Form (DRF) and physical security certificates to the DP |
| 2 | 🔍 Verification | DP forwards the dematerialisation request to the issuer/RTA and depository for processing and verification |
| 3 | ✂️ Cancellation of Physical Certificates | Upon successful dematerialisation, the physical certificates are cancelled and rendered invalid as evidence of holding |
| 4 | 💻 Electronic Credit | The corresponding securities are credited electronically to the investor's Demat account through the depository |
Steps to Dematerialise Physical Shares:
- The investor obtains a Demat Request Form (DRF) from their Depository Participant.
- The investor fills out the DRF and submits it to the DP along with the physical share certificates.
- A separate DRF must be filled out for each unique ISIN.
- Upon processing, the physical certificates are canceled/destroyed, and equivalent electronic units are credited to the investor's beneficiary account with the DP.
Odd Lot Share Dematerialisation
- Physical shares held in odd lots (non-standard marketable units) can be fully dematerialised without any restriction.
6.2.7 Fungibility and Distinctive Numbers
- No Distinctive Numbers: Unlike physical certificates which bear unique certificate and folio numbers, dematerialised shares do not have distinctive numbers.
- Fungibility: Dematerialised securities are fully fungible, meaning all units of a particular security are completely identical, uniform, and interchangeable with one another.
6.2.8 Rematerialisation (Remat) Process & RRF
What is Rematerialisation?
Rematerialisation is the exact reverse of dematerialisation. It is the process by which electronic security balances in a demat account are converted back into physical paper certificates.
Steps for Rematerialisation:
- The investor submits a Remat Request Form (RRF) to their Depository Participant.
- The DP forwards the request to the depository and issuer company.
- The electronic balance is debited, and fresh physical share certificates are printed and issued to the investor.
6.2.9 Multi-Asset Dematerialisation Capability
Demat accounts are not restricted to equity shares alone. Investors can hold a wide variety of financial assets in a single demat account, including:
- Equity Shares.
- Debt Instruments & Corporate Bonds.
- Mutual Fund Units.
- Government Securities (G-Secs) and T-Bills.
