1.1 A bond is a debt instrument in which an investor loans money to an entity (typically corporate or government) which borrows the funds for a defined period of time at a variable or fixed interest rate. Bonds are used by companies, municipalities, states and sovereign governments to raise money to finance a variety of projects and activities. Owners of bonds are debt holders, or creditors, of the issuer.

What is a Government Security (G-Sec)?

1.2 A Government Security (G-Sec) is a tradeable instrument issued by the Central Government or the State Governments. It acknowledges the Government’s debt obligation. Such securities are short term (usually called treasury bills, with original maturities of less than one year) or long term (usually called Government bonds or dated securities with original maturity of one year or more). In India, the Central Government issues both, treasury bills and bonds or dated securities while the State Governments issue only bonds or dated securities, which are called the State Development Loans (SDLs). G-Secs carry practically no risk of default and, hence, are called risk-free gilt-edged instruments.

a. Treasury Bills (T-bills)

1.3 Treasury bills or T-bills, which are money market instruments, are short term debt instruments issued by the Government of India and are presently issued in three tenors, namely, 91 day, 182 day and 364 day. Treasury bills are zero coupon securities and pay no interest. Instead, they are issued at a discount and redeemed at the face value at maturity. For example, a 91 day Treasury bill of ₹100/- (face value) may be issued at say ₹ 98.20, that is, at a discount of say, ₹1.80 and would be redeemed at the face value of ₹100/-. The return to the investors is the difference between the maturity value or the face value (that is ₹100) and the issue price (for calculation of yield on Treasury Bills please see answer to question no. 26).

b. Cash Management Bills (CMBs)

1.4 In 2010, Government of India, in consultation with RBI introduced a new short-term instrument, known as Cash Management Bills (CMBs), to meet the temporary mismatches in the cash flow of the Government of India. The CMBs have the generic character of T-bills but are issued for maturities less than 91 days.

c. Dated G-Secs

1.5 Dated G-Secs are securities which carry a fixed or floating coupon (interest rate) which is paid on the face value, on half-yearly basis. Generally, the tenor of dated securities ranges from 5 years to 40 years.

The Public Debt Office (PDO) of the Reserve Bank of India acts as the registry / depository of G-Secs and deals with the issue, interest payment and repayment of principal at maturity. Most of the dated securities are fixed coupon securities.

The nomenclature of a typical dated fixed coupon G-Sec contains the following features - coupon, name of the issuer, maturity year. For example, - 7.17% GS 2028 would mean:

Coupon	: 7.17% paid on face value
Name of Issuer	: Government of India
Date of Issue	: January 8, 2018
Maturity	: January 8, 2028
Coupon Payment Dates	: Half-yearly (July 08 and January 08) every year
Minimum Amount of issue/ sale	: ₹10,000

In case, there are two securities with the same coupon and are maturing in the same year, then one of the securities will have the month attached as suffix in the nomenclature. eg. 6.05% GS 2019 FEB, would mean that G-Sec having coupon 6.05% that mature in February 2019 along with the other similar security having the same coupon. In this case, there is another paper viz. 6.05%GS2019 which bears same coupon rate and is also maturing in 2019 but in the month of June. Each security is assigned a unique number called ISIN (International Security Identification Number) at the time of issuance itself to avoid any misunderstanding among the traders.

If the coupon payment date falls on a Sunday or any other holiday, the coupon payment is made on the next working day. However, if the maturity date falls on a Sunday or a holiday, the redemption proceeds are paid on the previous working day.

1.6 Instruments:

i) Fixed Rate Bonds – These are bonds on which the coupon rate is fixed for the entire life (i.e. till maturity) of the bond. Most Government bonds in India are issued as fixed rate bonds.

For example – 8.24%GS2018 was issued on April 22, 2008 for a tenor of 10 years maturing on April 22, 2018. Coupon on this security will be paid half-yearly at 4.12% (half yearly payment being half of the annual coupon of 8.24%) of the face value on October 22 and April 22 of each year.

ii) Floating Rate Bonds (FRB) – FRBs are securities which do not have a fixed coupon rate. Instead it has a variable coupon rate which is re-set at pre-announced intervals (say, every six months or one year). FRBs were first issued in September 1995 in India. For example, a FRB was issued on November 07, 2016 for a tenor of 8 years, thus maturing on November 07, 2024. The variable coupon rate for payment of interest on this FRB 2024 was decided to be the average rate rounded off up to two decimal places, of the implicit yields at the cut-off prices of the last three auctions of 182 day T- Bills, held before the date of notification. The coupon rate for payment of interest on subsequent semi-annual periods was announced to be the average rate (rounded off up to two decimal places) of the implicit yields at the cut-off prices of the last three auctions of 182 day T-Bills held up to the commencement of the respective semi-annual coupon periods.

iii) The Floating Rate Bond can also carry the coupon, which will have a base rate plus a fixed spread, to be decided by way of auction mechanism. The spread will be fixed throughout the tenure of the bond. For example, FRB 2031 (auctioned on May 4, 2018) carry the coupon with base rate equivalent to Weighted Average Yield (WAY) of last 3 auctions (from the rate fixing day) of 182 Day T-Bills plus a fixed spread decided by way of auction. Zero Coupon Bonds – Zero coupon bonds are bonds with no coupon payments. However, like T- Bills, they are issued at a discount and redeemed at face value. The Government of India had issued such securities in 1996. It has not issued zero coupon bonds after that.

iv) Capital Indexed Bonds – These are bonds, the principal of which is linked to an accepted index of inflation with a view to protecting the Principal amount of the investors from inflation. A 5 year Capital Indexed Bond, was first issued in December 1997 which matured in 2002.

v) Inflation Indexed Bonds (IIBs) - IIBs are bonds wherein both coupon flows and Principal amounts are protected against inflation. The inflation index used in IIBs may be Whole Sale Price Index (WPI) or Consumer Price Index (CPI). Globally, IIBs were first issued in 1981 in UK. In India, Government of India through RBI issued IIBs (linked to WPI) in June 2013. Since then, they were issued on monthly basis (on last Tuesday of each month) till December 2013. Based on the success of these IIBs, Government of India in consultation with RBI issued the IIBs (CPI based) exclusively for the retail customers in December 2013. Further details on IIBs are available on RBI website under FAQs.

vi) Bonds with Call/ Put Options – Bonds can also be issued with features of optionality wherein the issuer can have the option to buy-back (call option) or the investor can have the option to sell the bond (put option) to the issuer during the currency of the bond. It may be noted that such bond may have put only or call only or both options. The first G-Sec with both call and put option viz. 6.72% GS 2012 was issued on July 18, 2002 for a maturity of 10 years maturing on July 18, 2012. The optionality on the bond could be exercised after completion of five years tenure from the date of issuance on any coupon date falling thereafter. The Government has the right to buy-back the bond (call option) at par value (equal to the face value) while the investor had the right to sell the bond (put option) to the Government at par value on any of the half-yearly coupon dates starting from July 18, 2007.

vii) Special Securities - Under the market borrowing program, the Government of India also issues, from time to time, special securities to entities like Oil Marketing Companies, Fertilizer Companies, the Food Corporation of India, etc. (popularly called oil bonds, fertiliser bonds and food bonds respectively) as compensation to these companies in lieu of cash subsidies These securities are usually long dated securities and carry a marginally higher coupon over the yield of the dated securities of comparable maturity. These securities are, however, not eligible as SLR securities but are eligible as collateral for market repo transactions. The beneficiary entities may divest these securities in the secondary market to banks, insurance companies / Primary Dealers, etc., for raising funds.

Government of India has also issued Bank Recapitalisation Bonds to specific Public Sector Banks in 2018. These securities are named as Special GoI security and are non-transferable and are not eligible investment in pursuance of any statutory provisions or directions applicable to investing banks. These securities can be held under HTM portfolio without any limit.

viii) STRIPS – Separate Trading of Registered Interest and Principal of Securities. - STRIPS are the securities created by way of separating the cash flows associated with a regular G-Sec i.e. each semi-annual coupon payment and the final principal payment to be received from the issuer, into separate securities. They are essentially Zero Coupon Bonds (ZCBs). However, they are created out of existing securities only and unlike other securities, are not issued through auctions. Stripped securities represent future cash flows (periodic interest and principal repayment) of an underlying coupon bearing bond. Being G-Secs, STRIPS are eligible for SLR. All fixed coupon securities issued by Government of India, irrespective of the year of maturity, are eligible for Stripping/Reconstitution, provided that the securities are reckoned as eligible investment for the purpose of Statutory Liquidity Ratio (SLR) and the securities are transferable. The detailed guidelines of stripping/reconstitution of government securities is available in RBI notification IDMD.GBD.2783/08.08.016/2018-19 dated May 3, 2018. For example, when ₹100 of the 8.60% GS 2028 is stripped, each cash flow of coupon (₹ 4.30 each half year) will become a coupon STRIP and the principal payment (₹100 at maturity) will become a principal STRIP. These cash flows are traded separately as independent securities in the secondary market. STRIPS in G-Secs ensure availability of sovereign zero coupon bonds, which facilitate the development of a market determined zero coupon yield curve (ZCYC). STRIPS also provide institutional investors with an additional instrument for their asset liability management (ALM). Further, as STRIPS have zero reinvestment risk, being zero coupon bonds, they can be attractive to retail/non-institutional investors. Market participants, having an SGL account with RBI can place requests directly in e-kuber for stripping/reconstitution of eligible securities (not special securities). Requests for stripping/reconstitution by Gilt Account Holders (GAH) shall be placed with the respective Custodian maintaining the CSGL account, who in turn, will place the requests on behalf of its constituents in e-kuber.

ix) Sovereign Gold Bond (SGB): SGBs are unique instruments, prices of which are linked to commodity price viz Gold. SGBs are also budgeted in lieu of market borrowing. The calendar of issuance is published indicating tranche description, date of subscription and date of issuance. The Bonds shall be denominated in units of one gram of gold and multiples thereof. Minimum investment in the Bonds shall be one gram with a maximum limit of subscription per fiscal year of 4 kg for individuals, 4 kg for Hindu Undivided Family (HUF) and 20 kg for trusts and similar entities notified by the Government from time to time, provided that (a) in case of joint holding, the above limits shall be applicable to the first applicant only; (b) annual ceiling will include bonds subscribed under different tranches during initial issuance by Government and those purchased from the secondary market; and (c) the ceiling on investment will not include the holdings as collateral by banks and other Financial Institutions. The Bonds shall be repayable on the expiration of eight years from the date of issue of the Bonds. Pre-mature redemption of the Bond is permitted after fifth year of the date of issue of the Bonds and such repayments shall be made on the next interest payment date. The bonds under SGB Scheme may be held by a person resident in India, being an individual, in his capacity as an individual, or on behalf of minor child, or jointly with any other individual. The bonds may also be held by a Trust, HUFs, Charitable Institution and University. Nominal Value of the bonds shall be fixed in Indian Rupees on the basis of simple average of closing price of gold of 999 purity published by the India Bullion and Jewelers Association Limited for the last three business days of the week preceding the subscription period. The issue price of the Gold Bonds will be ₹ 50 per gram less than the nominal value to those investors applying online and the payment against the application is made through digital mode. The Bonds shall bear interest at the rate of 2.50 percent (fixed rate) per annum on the nominal value. Interest shall be paid in half-yearly rests and the last interest shall be payable on maturity along with the principal. The redemption price shall be fixed in Indian Rupees and the redemption price shall be based on simple average of closing price of gold of 999 purity of previous 3 business days from the date of repayment, published by the India Bullion and Jewelers Association Limited. SGBs acquired by the banks through the process of invoking lien/hypothecation/pledge alone shall be counted towards Statutory Liquidity Ratio. The above subscription limits, interest rate discount etc. are as per the current scheme and are liable to change going forward.

x) 7.75% Savings (Taxable) Bonds, 2018: Government of India has decided to issue 7.75% Savings (Taxable) Bonds, 2018 with effect from January 10, 2018 in terms of GoI notification F.No.4(28) - W&M/2017 dated January 03, 2018 and RBI issued notification vide IDMD.CDD.No.1671/13.01.299/2017-18 dated January 3, 2018.

SDLs are dated securities issued through normal auction similar to the auctions conducted for dated securities issued by the Central Government (please see question 3). Interest is serviced at half-yearly intervals and the principal is repaid on the maturity date. Like dated securities issued by the Central Government, SDLs issued by the State Governments also qualify for SLR. They are also eligible as collaterals for borrowing through market repo as well as borrowing by eligible entities from the RBI under the Liquidity Adjustment Facility (LAF) and special repo conducted under market repo by CCIL. State Governments have also issued special securities under “Ujjwal Discom Assurance Yojna (UDAY) Scheme for Operational and Financial Turnaround of Power Distribution Companies (DISCOMs)” notified by Ministry of Power vide Office Memorandum (No 06/02/2015-NEF/FRP) dated November 20, 2015.
