Government Securities: T-Bills, G-Secs and RBI Retail Direct

Investing in India — Layer 1

When the Government of India needs to borrow, it issues securities through RBI auctions. Buy one and you become the government’s lender — the same sovereign promise behind PPF and post office schemes, but in direct, tradeable form. Default risk on a rupee-denominated G-sec is as close to zero as Indian finance offers — the government controls the currency its debt is issued in. There is no DICGC ceiling to manage because no insurance is needed. This is the true “risk-free rate” against which everything else in this pillar is priced.

The Instruments

What you’re actually buying

The G-sec family has four main members:

• Treasury Bills (T-bills): short-term — 91, 182, and 364 days. No interest payments; issued at a discount and redeemed at face value (buy at ₹98.6, receive ₹100 — the gap is your return).
• Dated G-secs: long-term bonds, from 1 year out to 40+ years. Pay a fixed coupon every six months, return face value at maturity.
• State Development Loans (SDLs): the same structure issued by state governments — a whisker more yield for a whisker less pristine (though still effectively sovereign-backstopped) credit.
• Floating Rate Bonds and Sovereign Green Bonds also exist; beginners can safely ignore them for now.

How Yields Work

The seesaw everyone must understand before buying

Where the current numbers sit: short T-bills yield a little above the RBI’s 5.25% repo rate, while the benchmark 10-year G-sec trades around 6.7% as of early July 2026. Between those two points runs the yield curve — the line connecting yields across maturities. It usually slopes upward because lenders demand more for locking money away longer. That extra ~1.4% for going from 3 months to 10 years is the market’s price for a decade of uncertainty about inflation and rates.

The seesaw everyone must understand: bond prices and yields move opposite each other. If you buy a 10-year bond at 6.7% and market yields later rise to 7.5%, your bond’s market price falls — nobody pays full price for the lower coupon. Yields fall instead, and your bond’s price rises. Two consequences:

• Held to maturity, none of this matters — you get every coupon and the face value regardless of the journey. This is the retail investor’s superpower: institutions must mark to market; you don’t.
• Sold early, it matters entirely — and the longer the bond, the bigger the price swings. A 30-year G-sec is a genuinely volatile instrument in the interim, sovereign or not.

So the honest framing: G-secs are risk-free at maturity, price-risky in between. Match the maturity to your goal date and the risk largely dissolves.

How To Buy

RBI Retail Direct — free, direct, and almost unknown

Since 2021 the RBI runs a free platform for individuals — RBI Retail Direct (rbiretaildirect.org.in, plus a mobile app since 2024). The process:

1. Open a Retail Direct Gilt (RDG) account online — PAN, a bank account, email, mobile. No fees to open or maintain, no brokerage.
2. Bid in primary auctions — T-bills weekly, dated G-secs and SDLs on their calendars — as a non-competitive bidder: you accept the auction-determined yield, minimum ₹10,000, and small bids are essentially always allotted.
3. Or buy/sell in the secondary market through the NDS-OM screen the platform gives you access to.
4. Coupons and redemptions land automatically in your linked bank account.

Alternative routes: most large brokers now offer G-sec access via demat, and there are apps built on top of the same plumbing. Fine too — Retail Direct’s advantage is being free and first-party.

The catch nobody hides but nobody advertises: retail secondary-market liquidity is thin. The benchmark 10-year trades actively; an off-the-run bond may see sparse quotes, so selling mid-way can mean accepting a haircut. The platform is excellent for buy-and-hold-to-maturity; treat early exit as possible but not free.

Taxation

Where G-secs shine and where they don’t

Coupons and T-bill discounts are taxed at your slab rate as interest income — no concessional treatment, and the coupons arrive as cash whether or not you need them (no compounding option, unlike a cumulative FD). Capital gains if sold before maturity: listed G-secs held over 12 months qualify as long-term, taxed at 12.5% without indexation; shorter, at slab. No TDS on government securities for residents — but the income must still be declared.

The slab taxation is the biggest practical drawback versus PPF/SSY (tax-free) and matters most in the 30% bracket, where a 6.7% G-sec nets ~4.6%. In the 0–10% brackets, G-secs get much more interesting.

Where They Fit

The right and wrong uses for G-secs

Use case	Verdict	Why
Dated goal beyond FD territory (5–15 yrs)	✅ Strong fit	Lock today’s ~6.7–7.1% to a specific maturity date with sovereign safety
Large safe corpus above ₹5L per bank	✅ Strong fit	No DICGC ceiling to juggle; semi-annual coupons mimic a pension
T-bill ladder as emergency-fund tier	✅ Works well	Yield ≈ liquid funds, safety better; slightly more effort
High-bracket investor with PPF/VPF headroom	⚠️ PPF/VPF first	Those beat G-secs post-tax; use G-secs after the tax-free buckets are full
Betting on rate cuts via long bonds	❌ Wrong tool	That’s trading, not saving — belongs in the risk-money layer if anywhere

The mutual fund route: gilt funds and target-maturity funds hold the same securities with professional management and easy liquidity. The trade-offs: expense ratios, and for regular gilt funds, the manager’s duration bets replace your control. Target-maturity funds — which hold to a fixed year like your own ladder would — are the closest packaged substitute. Post-2023, both routes are slab-taxed for fresh money, so the choice is mostly about convenience versus control, not tax.

Frequently Asked Questions

Your questions answered

Are G-secs safer than bank FDs?

Strictly, yes. FDs depend on the bank, insured to ₹5 lakh per bank; G-secs depend on the Government of India directly, with no ceiling. For amounts within the DICGC limit the practical difference is negligible — beyond it, the G-sec is the more conservative instrument. See our FD and RD guide for the full deposit picture.

What’s the minimum investment and are there any charges?

₹10,000 (face value) in primary auctions via RBI Retail Direct, in multiples of ₹10,000. The platform charges nothing — no account fee, no brokerage. Broker platforms may charge their usual fees.

Can I lose money in a G-sec?

Not by default, and not if held to maturity in nominal terms. You can realise a loss by selling before maturity after yields have risen — the longer the bond, the larger the possible swing. Inflation eroding real value is the other, quieter risk shared by every fixed-rate instrument.

G-sec or gilt fund — which should a beginner pick?

If the plan is hold-to-maturity for a dated goal: the direct G-sec or a target-maturity fund, since both remove the interim price risk from the outcome. If the plan involves flexible amounts and easy exits: a fund. Direct ownership costs nothing annually; funds charge a TER but handle everything. Our Mutual Funds guide covers debt fund categories in detail.

Why does everyone quote the “10-year yield” on business news?

It’s the economy’s reference interest rate — the benchmark off which corporate bonds, and indirectly home loans and valuations, are priced. When the 10-year moves, the cost of money in India has moved. Watching it is how bond investors read the market’s inflation and rate expectations in one number.
