NISM Series VI Study Notes: Chapter XI – Special Services: Debt Instruments and Government Securities

This comprehensive study guide provides highly structured, exam-focused notes on Chapter XI: Special Services – Debt Instruments & Government Securities under the NISM Series VI Depository Operations Certification. It outlines the electronic management of fixed-income assets, Certificates of Deposit, Commercial Papers, and Government Securities in the Indian depository system.

1. Legal and Operational Framework of Debt Instruments

What is a Debt Security?

A debt security (or debt instrument) is a formal written agreement to repay a loan, usually with interest, within a designated time frame. The specific characteristics associated with a debt instrument differentiate it from other asset classes.

These distinct features include:

• Coupon / Interest Rate: The periodic interest rate paid to the investor.
• Redemption / Maturity Date: The date on which the principal loan amount is scheduled to be repaid.
• Security Status: Whether the instrument is backed by collateral (secured) or not (unsecured).
• Embedded Options: The presence of special terms, such as a put option or a call option, if any are specified in the issue terms.

Classification of Debt Instruments

Based on the issuer type, maturity profile, and underlying payment structures, debt instruments in the financial markets are classified into several major categories:

• Bonds
• Debentures
• Commercial Paper (CP)
• Treasury Bills (T-bills)

Depository Identification: ISIN & Instrument Descriptor

To ensure systematic tracking within the electronic registry, every debt security is assigned a unique identity in the depository database. This tracking relies on two primary components:

1. International Securities Identification Number (ISIN): A unique, separate code assigned to identify each instrument in the depository system.
2. Instrument Descriptor: An electronic tag linked to the ISIN that indicates the key parameters of the underlying security. The instrument descriptor in the depository system specifically displays:
   • The complete name of the Issuer.
   • The Coupon or Interest Rate.
   • The formal security name.
   • The scheduled redemption date.
   • The Face Value of the instrument.

2. Administering Corporate Debt in the Depository

Adding a New Debt Instrument to the Depository

An issuer of bonds or debentures must complete specific operational steps to enable electronic dematerialisation for investors:

1. Submission of Request: The issuer sends a formal request to the depositories detailing the specific type of debt instrument.
2. Letter of Intent (LOI): The request must be accompanied by an official Letter of Intent.
3. Tripartite Agreement: Once the depository accepts the request, a tripartite agreement is formally signed between the depository, the issuer, and the designated Registrar & Transfer Agent (RTA).
4. Admission: Following the execution of this agreement, the depository admits the debt securities and makes them available for dematerialisation by investors.

Accounts and Dematerialisation Rules

• No Dedicated Accounts Required: The depositories impose no regulatory restrictions on using existing demat accounts to hold debt instruments. It is entirely up to the convenience of the investors whether they want to open a separate demat account for fixed-income assets or keep all holdings in a single account.
• Standard Demat Process: The operational workflow for dematerialising corporate debt instruments is identical to the procedure followed for equity shares.

Cash Corporate Actions & Embedded Options

• Interest Distributions: The distribution of interest payments for debt instruments is handled in the same manner as cash corporate benefits for equity shares. The corporate issuer dispatches the interest warrant directly to the eligible electronic holder.
• Put and Call Options: Exercising an embedded call or put option does not alter the fundamental redemption mechanics; it simply prepones (moves forward) the redemption date of the debt instrument.
  • If an issuer decides to exercise a call option, the operational procedure followed is exactly the same as a normal scheduled redemption.
  • Upon completing the prescribed administrative procedures, the issuer distributes the redemption proceeds directly to the investor.

3. Money Market Instruments: Certificates of Deposit (CD)

A Certificate of Deposit (CD) is a short-term, negotiable money market instrument. The depository system handles the issuance, holding, and redemption of CDs electronically.

Key Operational Rules for CDs

• Account Holding Options: Just like corporate debt, investors have the choice of holding their CDs in a separate demat account or consolidating all their financial holdings within a single account.
• Minimum Size Threshold: The minimum investment size required to subscribe or transact in Certificates of Deposit through the depository system is Rs. 1 lakh.

The Dematerialisation Process for CDs

1. The demat procedure for physical CD certificates is identical to the process used for equity shares.
2. The client submits a formal request to their Depository Participant (DP) using the standard Dematerialisation Request Form (DRF), accompanied by the physical CD certificates.
3. Mandatory Endorsement: Prior to submitting the CD to the DP, the client/holder must write an endorsement in the designated space on the reverse of the physical CD certificate, which must be signed by an authorised official of the holding entity.

CD Redemption Workflow at Maturity

Because CDs are high-value, time-sensitive money market instruments, their electronic redemption follows a strict operational timeline:

1. Redemption Account: The issuing bank/corporate must open a dedicated redemption account with a Depository Participant.
2. Submission of DIS: The investor holding the demat CDs must submit a Delivery Instruction Slip (DIS) to their DP to transfer the matured CDs.
3. Strict Transfer Deadline: The transfer of CDs into the Issuer's Redemption Account must execute successfully by 3:00 p.m. at least two working days prior to the scheduled maturity date.

4. Money Market Instruments: Commercial Paper (CP)

A Commercial Paper (CP) is an unsecured, short-term money market instrument issued in the form of a promissory note.

Key Operational Rules for CPs

• Minimum Subscription Size: An investor can subscribe to Commercial Papers in the depository system for a minimum face value of Rs. 5,00,000, or in multiples thereof. The face value of a single electronic CP unit is fixed at Rs. 5,00,000.
• Admission Constraint: An investor can only dematerialise physical CPs if the specific commercial papers have been formally admitted and made available for dematerialisation by the respective issuer.
• Demat Workflow: To convert physical CPs into demat holdings, the client submits the physical paper along with the standard demat request form (available with the DP) to their participant.

Trading and Settlement of Debt & CPs

• Negotiated Terms: The buyer and the seller directly negotiate and decide upon the transaction price and quantity of the debt securities or CPs to be traded.
• Electronic Transfer: The selling investor authorizes their DP through written delivery instructions to debit their account and transfer the securities directly into the buyer's demat account.
• Any Depository: The buyer may hold their demat account with the same DP or with a DP registered under another depository.
• Identical Process: For both buying and selling transactions in dematerialised debt instruments, the operational procedures for delivery, receipt, and transfer are exactly the same as those used for equity shares.

5. Government Securities (G-Secs)

Government Security (G-Sec) means a security created and issued by either the Central Government or a State Government for the purpose of raising a public loan.

Classification of G-Secs

Government securities are categorized into two primary types based on their maturity duration:

The Role of the RBI and Public Debt Office

All primary market activities relating to government securities are managed in a centralized manner:

• Centralised Administration: The Reserve Bank of India (RBI), through its Public Debt Office (PDO), handles all key G-Sec activities, including issue management, trade settlement, interest distribution, and final redemptions.

SGL Accounts and Depository Linkages

• SGL Account Maintenance: Depositories in India have been granted explicit regulatory permission to maintain Subsidiary General Ledger (SGL) accounts representing investors' collective holdings through their network of DPs.
• Unified Client Account: Any standard client demat account opened with a registered DP can be utilized for holding and transacting in government securities. Consequently, an investor can manage equity shares, mutual fund units, and G-Secs within a single demat account.
• Dual Formats: Government securities can be held either in physical paper form or as electronic entries in an SGL account.
• R&TA Representation: Within the G-Sec framework, the depository acts as the Registrar and Transfer Agent (R&TA) and discharges all standard RTA functions.

G-Sec Demat Rejections & Communication Loop

If an investor requests the dematerialisation of physical government securities, the request is routed through a specialized G-Sec cell:

1. The Rejection Trigger: The depository’s G-Sec cell will reject a demat request if the Reserve Bank of India (RBI) rejects the underlying transfer. The RBI commonly rejects transfers due to:
   • A signature mismatch on the physical documents.
   • The signing officials/signatories not being registered with the RBI.
2. DP Notification Duty: In the event of a rejection, the DP must immediately intimate the client.
3. Format of Intimation: This communication must be sent via a formal letter or fax, enclosing the official rejection memo generated by the depository's G-Sec cell.

Transfer and Account Maintenance

• Standard Transfers: The administrative procedure for transferring government securities between beneficial owner accounts within the depository is exactly identical to the transfer process used for equity shares.
• Critical Account Updates: DPs must ensure that any critical updates to the beneficial owner's account—such as changes in bank details or registered addresses—are fully updated well in advance of the interest payment or redemption due date.

Distribution of G-Sec Interest Payments

Because G-Secs are issued by the sovereign, the distribution of interest follows a strict sequence to ensure that funds are received from the central bank before being disbursed to individual investors:

1. RBI Funding: The Reserve Bank of India (RBI) credits the aggregate interest amount to the depository's account.
2. Depository Distribution: The depository distributes the respective interest payments to the eligible clients who hold G-Sec balances on which interest is due.
3. Strict Timeline: The depository must complete this distribution before the End of Day (EOD) of the interest payment due date, but only after the RBI has officially made the funds available to the depository.

6. Important Terms Glossary

• Debt Instrument: A written contract outlining the terms of a loan, including the repayment of principal and interest within a specified time frame.
• Instrument Descriptor: An electronic description in the depository system that indicates the issuer, coupon, security name, redemption date, and face value.
• Tripartite Agreement: A contract signed between the issuer, the depository, and the RTA to enable demat services for a specific security.
• Call/Put Option: Embedded terms that allow the issuer (call) or the investor (put) to prepone the scheduled redemption date of an instrument.
• Certificate of Deposit (CD): A negotiable money market instrument with a minimum subscription denomination of Rs. 1 lakh in the depository system.
• Commercial Paper (CP): An unsecured short-term debt instrument with a minimum subscription/face value denomination of Rs. 5,00,000.
• Dated Securities: Long-term Government Securities with a maturity period exceeding one year.
• Treasury Bills (T-Bills): Short-term Government Securities with a maturity period of up to one year.
• Subsidiary General Ledger (SGL): A specialized ledger account maintained with the RBI in which government securities are held in electronic book-entry form.

7. Exam-Focused Key Takeaways

1. Unified Holding Capability: An investor does not need separate accounts for different asset classes; equity, mutual funds, and government securities can all be held in a single demat account.
2. CD Transact Limits: The minimum face value of a CD transaction is Rs. 1 lakh. For a CP transaction, the minimum face value is Rs. 5 lakh.
3. CD Maturity Deadline: Delivery Instruction Slips for CD redemption must be executed to the issuer's redemption account by 3:00 p.m. at least two working days prior to maturity.
4. Option Impacts: Call or put options do not alter the redemption procedure; they only prepone the redemption date.
5. G-Sec Rejection Flow: Rejections of G-Sec demat requests originate from the RBI and are communicated to the investor by the DP via a letter or fax containing the G-Sec cell's rejection memo.
6. Interest Disbursement Timing: Depository interest payments on G-Secs must be credited to client accounts before the EOD of the payment due date, subject to the RBI crediting the depository first.
