12. What Is the Difference Between Treasury Bills and Government Bonds?
Treasury Bills (T-Bills) and Government Bonds (also called G-Secs) are two fundamental instruments used by the Government of India to raise funds. While both are government-backed and considered safe investment options, they are vastly different in their structure, tenure, interest payout, and investment objectives.
Understanding these differences is essential for investors, portfolio managers, and institutions seeking to balance short-term liquidity and long-term fixed income in their asset allocations.
Definition and Core Purpose
Treasury Bills (T-Bills)
T-Bills are short-term debt instruments issued by the government to meet its temporary cash flow requirements. They do not pay interest but are issued at a discounted price and redeemed at face value.
Government Bonds (G-Secs)
Government Bonds are long-term borrowing instruments, typically used to fund infrastructure, defence, and fiscal expenses. They pay a fixed or floating rate of interest, known as the coupon, at regular intervals.
Tenure (Maturity Period)
| Instrument | Maturity Duration |
|---|---|
| Treasury Bills | Short-term: 91, 182, and 364 days |
| Government Bonds | Long-term: Ranges from 1 to 40 years |
T-Bills are ideal for short-term investors or for parking idle funds, while G-Secs are preferred by long-term income-seeking investors.
Interest Structure
| Feature | Treasury Bills (T-Bills) | Government Bonds |
|---|---|---|
| Interest Paid? | No | Yes |
| Payment Method | Issued at discount, redeemed at face value | Periodic coupon payments (semi-annual) |
| Example | Buy for ₹97, get ₹100 on maturity | Buy a ₹100 bond with 7% coupon; earn ₹7/year |
T-Bills offer a lump-sum return, while G-Secs provide periodic income.
How Returns Are Structured
T-Bill Example
- A 91-day T-Bill with a face value of ₹100 is issued at ₹97.50.
- On maturity, you receive ₹100.
- Return = ₹100 – ₹97.50 = ₹2.50
- This return is considered interest income and taxed accordingly.
Government Bond Example
- A 10-year bond with a 7.26% coupon and ₹100 face value will pay ₹3.63 every 6 months.
- You will receive ₹100 principal after 10 years.
- Total earning = ₹7.26 per year × 10 = ₹72.60 + ₹100 principal

Tax Implications
