In summary
Government Securities are tradable debt instruments through which the Central or State Governments borrow money. The Reserve Bank of India manages auctions and related operations for Central Government securities and State Development Loans.
- G-Secs represent government borrowing from investors
- Treasury Bills are short-term government securities
- Dated G-Secs usually pay periodic coupons
- States issue State Development Loans
- Current ten-year yield is around 7.22%
- Market prices can rise or fall
- G-Sec income is generally taxable
India's benchmark 6.94% Government Security 2036 was yielding about 7.2213% on October 2026. Bond yields change with market conditions, so this figure should always be read with its date and time.
What are government securities?
Government Securities, commonly called G-Secs, are tradable instruments issued by the Central Government or State Governments to borrow money.
The RBI defines a G-Sec as an instrument that acknowledges a government's debt obligation. The Central Government issues both short-term Treasury Bills and longer-term dated securities. State Governments issue dated securities known as State Development Loans or SDLs.
When you buy a G-Sec, you lend money to the government.
Depending on the security, you may earn periodic interest or earn a return from the difference between its purchase and maturity value.
Why does the government issue G-Secs?
The government issues G-Secs to meet its borrowing and funding requirements.
Common purposes include:
- Budget funding: Helps finance government expenditure
- Infrastructure spending: Supports public development projects
- Fiscal management: Helps meet government borrowing needs
- Cash management: Covers temporary funding mismatches
- Debt management: Helps refinance existing government borrowing
Government bond yields also form an important reference point for other interest rates in the financial system.
What are the main types of government securities?
Government Securities differ by maturity, issuer, and payment structure. Here are the details:
| Type | Issuer | Main feature |
| Treasury Bills | Central Government | Short-term and zero coupon |
| Dated G-Secs | Central Government | Longer maturity and usually coupon-paying |
| State Development Loans | State Governments | Dated state borrowing |
| Cash Management Bills | Central Government | Usually below 91 days |
How do government securities work?
G-Secs work by allowing investors to lend money to the government for a defined period.
Consider a simple example.
Suppose you buy Rs. 1 lakh face value of a dated G-Sec carrying a 7% annual coupon.
If the coupon is paid half-yearly, you would receive:
- Rs. 3,500 after six months
- Rs. 3,500 after another six months
- Rs. 7,000 total annual coupon
You would receive the face value according to the security's repayment terms at maturity.
However, this does not mean your investment return will always be exactly 7%.
If you buy or sell the security in the market at a price different from its face value, your actual yield can differ from its coupon.
What is the difference between coupon rate and yield?
The coupon rate is the stated interest rate on a bond's face value, while yield reflects the return based on its market price.
Suppose a bond has:
- Face value of Rs. 100
- Annual coupon of Rs. 7
- Coupon rate of 7%
If the bond's market price falls below Rs. 100, its yield to a new buyer generally rises.
If its price rises above Rs. 100, its yield generally falls.
This is why bond prices and yields normally move in opposite directions.
Are Government Securities risk-free?
G-Secs carry very low default risk, but they are not free from every investment risk.
The RBI describes Government Securities as having practically no default risk in domestic currency. However, investors can still face price losses when they sell before maturity. Important risks include:
- Interest-rate risk: Bond prices can fall when rates rise
- Market risk: Selling before maturity may cause loss
- Inflation risk: Inflation can reduce real returns
- Reinvestment risk: Future cash flows may earn lower rates
- Liquidity risk: Some G-Secs may trade less frequently
Your risk profile should therefore still be considered before investing.
How can retail investors buy Government Securities?
Retail investors can buy Government Securities directly or gain indirect exposure through investment products.
The main routes include:
- RBI retail direct: Investors can open a Retail Direct Gilt account and participate in primary auctions or the secondary market
- Registered intermediaries: Certain brokers and other authorised intermediaries facilitate G-Sec transactions
- Stock exchange routes: Eligible securities may be available through exchange-based mechanisms
- Mutual funds: Gilt and debt mutual funds can provide indirect exposure
RBI Retail Direct currently allows access to Government of India T-Bills, dated securities, and SDLs. The RBI states that the minimum investment through the platform is generally Rs. 10,000 for T-Bills, dated G-Secs, and SDLs. A gilt mutual fund is different from holding a G-Sec directly. A fund's NAV changes as the value of its underlying securities changes.
What is the current 10-year government bond yield in India?
India's benchmark 10-year Government bond yield was about 7.22% 6 October 2026.
The benchmark 6.94% GS 2036 was yielding 7.2213% at 10:10 AM IST, compared with 7.2108% at the previous close. This yield is not a fixed savings rate.
It can move throughout the trading day due to factors such as:
- RBI policy expectations
- Inflation outlook
- Government borrowing supply
- Banking system liquidity
- Global bond yields
- Crude oil prices
- Investor demand
Always check the latest quote when comparing G-Sec yields.
What is the difference between Government bonds and Government Securities?
Government Securities is the wider category. A Government bond is generally a longer-term Government Security, while G-Secs also include shorter-term instruments such as Treasury Bills.
| Feature | Government securities | Government bonds |
| Scope | Broad category | Type of G-sec |
| T-bills included | Yes | No |
| Maturity | Short or long term | Usually longer term |
| Regular coupon | Depends on instrument | Usually applicable |
Therefore, all Government bonds are Government Securities, but not all Government Securities are bonds.
Conclusion
Government Securities allow investors to lend money to the Central or State Governments through instruments such as Treasury Bills, dated G-Secs, and SDLs. Their government backing gives them very low credit risk, but their market prices can still change when interest rates and bond yields move.
Investors should understand the difference between coupon and yield, check the maturity period, consider tax implications, and assess whether they plan to hold the security until maturity. Direct G-Secs and gilt mutual funds also work differently, so the right choice depends on liquidity needs and investment goals.
