Introduction to Government Debt Market

The Government Debt Market is the platform where the Union Government of India raises funds to finance fiscal deficits, infrastructure projects and other public expenditures. It is regulated by the Reserve Bank of India (RBI) and overseen by SEBI for market‑wide transparency. The market is highly liquid, making sovereign securities a cornerstone for both retail and institutional fixed‑income portfolios.

For an investment adviser, knowing the characteristics of government securities helps in constructing risk‑adjusted portfolios, meeting client liquidity needs, and complying with suitability norms under the SEBI (Investment Advisers) Regulations, 2018. The exam frequently asks about the purpose of issuing sovereign debt, the impact of RBI policy rates, and the mechanics of primary‑market auctions.

Key take‑aways for the exam include: the market is primarily a primary‑auction system, the securities are backed by the full faith and credit of the Government, and yields serve as benchmark rates for the entire fixed‑income universe in India.

• Government debt provides a risk‑free benchmark for pricing other assets.
• Advisers must disclose the credit quality and liquidity profile of sovereign securities to clients.

Treasury Bills (T‑Bills) are short‑term discount instruments with maturities of 91 days, 182 days and 364 days. They do not carry a coupon; instead, they are issued at a discount to face value and redeemed at par. T‑Bills are the most liquid government security and are used by the RBI to manage short‑term liquidity.

Government Bonds (G‑Bonds) are medium to long‑term securities, typically ranging from 5 to 30 years, and carry a fixed or floating coupon. They are issued to fund long‑term infrastructure and development projects. The coupon payments provide a steady income stream for investors.

State Development Loans (SDLs) are bonds issued by individual state governments. Their maturities usually span 5 to 10 years, and they carry a coupon that reflects the credit perception of the issuing state. SDLs allow states to raise funds for their own development needs while offering investors diversification across different state credit profiles.

Exam questions often ask you to match the instrument with its maturity range, coupon feature, and typical issuer. Remember that only T‑Bills are zero‑coupon instruments; G‑Bonds and SDLs pay periodic coupons.

All sovereign securities are issued through a competitive bidding auction conducted by the RBI. The auction calendar is published weekly, and participants submit bids indicating the quantity and the yield (or discount rate) they are willing to accept.

Two types of bids exist: competitive and non‑competitive. In a competitive bid, the investor specifies the maximum yield they are willing to accept; allocation is granted only if the bid is at or below the cut‑off yield. In a non‑competitive bid, the investor agrees to accept the cut‑off yield determined by the auction, guaranteeing allocation up to a prescribed limit.

For the exam, remember that non‑competitive bids are limited to ₹25 lakh per auction for retail investors and that the cut‑off yield becomes the benchmark yield for that issue. Mis‑understanding the distinction can lead to loss of marks in scenario‑based questions.

Government securities exhibit an inverse relationship between price and yield: when yields rise, prices fall, and vice‑versa. This relationship is fundamental for advisers when explaining price movements to clients and when calculating the cost of borrowing for the government.

For zero‑coupon instruments like T‑Bills, the price is derived directly from the discount yield. For coupon‑bearing securities, the price reflects the present value of all future cash flows discounted at the market yield.

Exam questions may present a price and ask you to compute the implied yield, or vice‑versa. Knowing the standard approximation formula helps you answer quickly without iterative calculations.

Since Treasury Bills do not pay coupons, their valuation is straightforward. The price is obtained by discounting the face value at the prevailing annual yield for the exact time to maturity. This formula is essential for advisers who need to calculate the exact investment amount for a client’s cash‑management goal.

The discount yield quoted in the auction is an annualised rate based on a 360‑day year. Converting that yield to a price requires the formula shown below. Remember that the yield used must match the bill’s actual days to maturity.

In the exam, you may be given the discount yield and asked to compute the purchase price, or the opposite. Using the correct formula avoids common arithmetic errors.

After issuance, government securities trade on the secondary market through exchanges (e.g., NSE, BSE) and over‑the‑counter platforms. The RBI acts as the central counter‑party, ensuring settlement within T+2 days for bonds and T+1 for T‑Bills.

Liquidity is highest for short‑term T‑Bills and benchmark G‑Bonds, which have deep order books and narrow bid‑ask spreads. SDLs, while liquid, may exhibit slightly wider spreads due to state‑specific credit perception.

Advisers should monitor secondary‑market yields because they reflect current market expectations and affect the valuation of existing holdings. Exam questions may test your understanding of price discovery, settlement cycles, and the impact of liquidity on yields.

The RBI’s repo rate serves as the policy benchmark for short‑term government securities. When the repo rate rises, the discount yields on new T‑Bills increase, pushing their prices down. Conversely, a rate cut lowers yields and raises prices.

Long‑term government bond yields are influenced by expectations of future policy moves, inflation outlook, and fiscal deficit trends. Advisers should relate changes in the policy rate to shifts in the yield curve, as exam scenarios often ask you to predict the direction of yields following a monetary‑policy announcement.

Remember that the Government of India’s borrowing programme is scheduled quarterly; any deviation from the announced schedule may cause temporary yield volatility, a nuance that appears in case‑study questions.
