Are government securities completely risk-free?

They carry effectively no credit risk since they are backed by the sovereign, but they are not free of interest rate risk. If sold before maturity when rates have risen, an investor may realise a lower price than what they paid.

What is the minimum amount needed to invest in a G-Sec through RBI Retail Direct?

₹10,000, and thereafter in multiples of ₹10,000, whether investing in a primary auction or the secondary market through the scheme.

What is the difference between a T-Bill and a dated G-Sec?

A T-Bill is a short-term, zero-coupon instrument with a maximum tenor of 364 days, issued at a discount and redeemed at face value, while a dated G-Sec is a longer-term instrument (5 to 40 years) that pays a fixed or floating coupon semi-annually.

Is interest from government securities tax-free?

Interest income from G-Secs, SDLs, and SGB coupons is fully taxable at the investor’s slab rate. Only the redemption gain on Sovereign Gold Bonds held to maturity by the original subscriber is tax-exempt.

Can I sell a G-Sec before its maturity date?

Yes, listed G-Secs can be sold in the secondary market before maturity, either through the RBI Retail Direct platform’s NDS-OM access or via a stockbroker, though the sale price will reflect prevailing market yields rather than the original face value.

How is TDS applied to G-Sec interest?

TDS under Section 193 is not deducted if interest from a single issuer stays within ₹10,000 in a financial year. Once this threshold is crossed, 10% TDS applies (or 20% if PAN is not furnished), and investors can claim any excess deducted as a refund while filing their return.

What happens if I don’t win a bid in the RBI Retail Direct auction?

Non-competitive bids under the Retail Direct Scheme are allotted at the cut-off yield/price determined by institutional bidders in that auction, so retail investors receive an allotment without needing to compete on price, subject to the auction’s overall allotment rules.

Are State Development Loans as safe as Central Government securities?

SDLs carry sovereign-linked backing similar to Central Government securities, though they are issued by individual states and may trade at a marginally different yield reflecting each state’s specific fiscal position, even though default risk remains extremely low in practice.

Government Securities in India: A Complete Guide

6 min read•Updated on 12th Sept, 2026•by Team Angel One

Government securities are debt instruments issued by governments to raise funds for fiscal requirements and public development projects. For decades, government securities were largely the domain of banks, insurers, and large institutions, out of reach for the everyday retail investor.

That changed with the RBI Retail Direct Scheme, which opened the door for individuals to invest directly in some of the safest instruments available in India’s debt market.

This article explains what government securities are, the different types available, and how you can invest.

Key Takeaways

Government securities are debt instruments issued by the RBI on behalf of the Central or State Government, backed by guarantees and considered virtually risk-free.
The main categories are Treasury Bills, dated G-Secs, State Development Loans, and Sovereign Gold Bonds.
The RBI Retail Direct Scheme allows individuals to invest directly with a minimum of ₹10,000, without needing a broker, in both primary auctions and the secondary market.
G-Sec prices and yields move inversely. When market interest rates rise, existing bond prices fall, and vice versa.
Interest earned on G-Secs is fully taxable at the investor’s applicable income tax slab rate under the ‘Income from Other Sources’ head.

What are Government Securities?

Government securities, commonly called G-Secs, are debt instruments issued by the Reserve Bank of India (RBI) on behalf of the Government of India (or state governments) to raise funds for public expenditure and manage the government’s borrowing programme. Because they are backed by the sovereign, G-Secs carry effectively no credit risk credit risk, though they remain exposed to interest rate risk if sold before maturity.

Types of Government Securities in India

Instrument	Issuer	Tenor	Key Feature
Treasury Bills (T-Bills)	Central Government	91, 182, or 364 days	Zero-coupon instruments, issued at a discount and redeemed at face value. No periodic interest payment
Cash Management Bills (CMBs)	Central Government	Less than 91 days	Used to manage short-term, temporary cash flow mismatches in government finances
Dated Government Securities	Central Government	5 to 40 years	Fixed or floating coupon paid semi-annually on face value. This is one of the most common forms of long-term G-Sec
State Development Loans (SDLs)	State Governments	1 year or more	Structured similarly to dated G-Secs, but issued by individual state governments to fund their borrowing needs
Sovereign Gold Bonds (SGBs)	Central Government (via RBI)	8 years (with early exit from year 5)	Denominated in grams of gold, paying 2.5% annual interest. Redemption value linked to prevailing gold prices. Note: no new SGB tranches have been issued since FY 2023-24. Existing bonds remain tradable in the secondary market
RBI Floating Rate Savings Bond (FRSB)	Central Government	7 years (fixed lock-in)	Interest rate resets every six months, linked to the National Savings Certificate rate plus a spread

How G-Sec Pricing and Yield Work

G-Sec prices and yields move in opposite directions. When a bond is issued, it carries a fixed coupon rate on its face value. Once it starts trading in the secondary market, its price fluctuates based on prevailing interest rates, and the yield (the effective return an investor earns) adjusts accordingly.

Yield to Maturity (approximate) = (Annual Coupon + ((Face Value − Purchase Price) ÷ Years to Maturity)) ÷ ((Face Value + Purchase Price) ÷ 2)

Example: A ₹100 face value G-Sec carries a 7% coupon (₹7 annually) and is trading at ₹96.54 in the secondary market with 14 years remaining to maturity.

Approximate Yield = (7 + ((100 − 96.54) ÷ 14)) ÷ ((100 + 96.54) ÷ 2) = (7 + 0.25) ÷ 98.27 ≈ 7.38%

This illustrates why a bond’s traded price below face value results in a yield higher than its stated coupon, and vice versa when trading above face value.

Interest Rate Risk: A Quick Reference

Market Interest Rate Movement	Impact on Existing G-Sec Prices	Impact on Yields
Rates rise	Prices fall	Yields rise
Rates fall	Prices rise	Yields fall

Longer-tenor G-Secs are sensitive to interest rate changes than shorter-tenor ones, a concept known as duration risk. Investors who hold a G-Sec to maturity are insulated from this price volatility and receive the full face value regardless of interim price swings.

How to Invest in Government Securities

Investment Route	Accessible Instrument Types
RBI Retail Direct	Central Government Securities (G-Secs), Treasury Bills (T-Bills), State Development Loans (SDLs), Sovereign Gold Bonds (SGBs)
NDS-OM	Institutional access for G-Secs, T-Bills, and SDLs
Stockbroker / Demat Account	G-Secs, T-Bills, SDLs, and SGBs via secondary market segments
Bond Ledger Account (BLA)	RBI Floating Rate Savings Bonds (FRSBs) available through designated agency banks (such as SBI and other authorised public/private sector banks) or SHCIL, rather than the three digital retail routes above.

Under the RBI Retail Direct Scheme, individuals can place a non-competitive bid, meaning they receive the same cut-off price/yield determined by larger institutional bidders in that auction, rather than setting the price themselves.

SEBI, RBI, and the Regulatory Framework for G-Sec

Government securities occupy a slightly different regulatory space compared to equities and corporate bonds:

RBI as debt manager: The Reserve Bank of India manages the public debt of both the Central Government and state governments, and directly issues G-Secs, T-Bills, SDLs, and SGBs through periodic auctions.

SEBI’s role in secondary trading: When G-Secs are listed and traded on stock exchanges like the NSE and BSE, SEBI’s regulatory framework governing exchange trading, broker conduct, and settlement applies to those transactions, even though the securities themselves are issued by RBI, not registered under SEBI’s ICDR framework.

NDS-OM: The Negotiated Dealing System-Order Matching platform, RBI’s screen-based system for secondary market G-Sec trading, was historically open only to institutions but is now accessible to retail investors through the Retail Direct Scheme.

Tax Treatment of Government Securities

Aspect	Tax Treatment
Interest income (coupon)	Fully taxable as “Income from Other Sources” at the investor’s applicable slab rate
TDS on interest	Exempt from TDS if interest from a single issuer does not exceed ₹10,000 in a financial year under Section 193. TDS at 10% applies once this threshold is crossed (20% without valid PAN)
Capital gains: Sold within 12 months (listed G-Sec)	Short-term capital gains taxed at the investor’s slab rate
Capital gains: Sold after 12 months (listed G-Sec)	Long-term capital gains taxed at 12.5%, without indexation, under the post-July 2024 rules
Sovereign Gold Bonds: Held to maturity	Redemption gains are tax-exempt for the original individual subscriber, a benefit unique to SGBs among government securities
Sovereign Gold Bond: Sold before maturity	Capital gains tax applies based on holding period, like other listed G-Secs, though the SGB’s periodic 2.5% interest remains taxable at slab rate regardless
TDS relief	Eligible investors can submit Form 15G (below 60 years) or Form 15H (senior citizens) to avoid TDS deduction if their total income is below the taxable threshold

Note: T-Bills, since they are zero-coupon instruments issued at a discount, generate their entire return as the difference between purchase and redemption price. This is treated as short-term capital gains (given the sub-364-day tenor) taxed at the slab rate, rather than as periodic “interest” income subject to TDS under Section 193.

Conclusion

Government securities offer something increasingly rare in a portfolio: a virtually risk-free way to earn a predictable return, now made directly accessible to retail investors through the RBI Retail Direct Scheme. Whether it’s a short-term T-Bill for parking surplus cash, a long-dated G-Sec for retirement-horizon income, or a Sovereign Gold Bond for a tax-efficient gold allocation, understanding how pricing, yield, and taxation work across these instruments helps investors use them effectively rather than treating them as a black box reserved for institutions.
