Treasury Bills (T-Bills).
India's Safest Place to Park Money for Under a Year.
Published as on 22 July 2026
A Treasury Bill is a short-term IOU from the Government of India — issued through the RBI in 91, 182 or 364-day tenures. You buy it at a discount and receive the full face value at maturity; the difference is your entire return. There is no coupon: a ₹1,00,000 bill bought for ₹98,500 pays back ₹1,00,000 in a year. As the shortest, safest rung of the government securities ladder, T-Bills carry minimal credit risk and almost no price volatility — but they are a capital-preservation tool, not a wealth engine. As of February 2026 the 364-day yields ~5.6%, about 35 bps over the 5.25% repo, and retail investors can buy from ₹10,000 on RBI Retail Direct.

Executive Summary · 6 Findings
A T-Bill is the government's working-capital loan — money it borrows for a few months to bridge the gap between when it spends and when taxes arrive. For an investor it answers one question: where do I keep money I will need within a year, with near-total safety of principal? The catch: "safe" means the principal, not the purchasing power. After tax and inflation, the real return can quietly turn negative.
Covers what a T-Bill is and why the government issues them, where they sit in the money-market layer of a portfolio, the four risks that survive the sovereign guarantee (reinvestment, inflation, secondary-market liquidity, opportunity), slab-rate STCG taxation and the advance-tax obligation, how to buy via RBI Retail Direct, T-Bills versus FDs and liquid funds, the ladder strategy, and seven questions Indian investors ask.
Key Findings
A zero-coupon loan to the government, under a year.
T-Bills are short-term securities issued by the Government of India through the RBI, in 91, 182 and 364-day tenures. They pay no interest — you buy at a discount and collect full face value at maturity. Pay ₹98,500 for a ₹1,00,000 bill, get ₹1,00,000 back; the ₹1,500 gap is your return. Auctioned weekly by the RBI.
The money-market layer — one step above cash.
In the portfolio hierarchy, T-Bills sit above a savings account but below short-term bonds and equity. Their job is the safe parking of funds needed within 12 months — next quarter's tax, a down payment six months out, a business liquidity reserve. Match the instrument's tenure to the goal's timeline.
"Low risk" is not "risk-free."
Credit risk is minimal and, at under a year, interest-rate risk is very low if held to maturity. But three risks survive: reinvestment risk (the next bill may yield less), inflation risk (a 5.6% yield loses to 6% inflation), and secondary-market liquidity risk (small odd-lots can face wide spreads). A sovereign guarantee protects your rupees, not their real value.
Always STCG at slab rate — and no TDS.
Because a T-Bill matures in under a year, its gain is always Short-Term Capital Gains, taxed at your slab rate — it can never qualify for LTCG. There is no TDS, so nothing is auto-deducted: if your total tax liability crosses ₹10,000 you must pay advance tax in quarterly instalments, or face interest under Sections 234B/234C. NRIs face 20% TDS.
Buy directly from ₹10,000 on RBI Retail Direct.
Open a free RBI Retail Direct account, add funds, and place a non-competitive bid — you specify only the amount (₹10,000 minimum) and accept the auction's weighted-average yield, without competing with institutions. Already have a demat account? Brokers like Zerodha Coin or ICICI Direct also offer T-Bills, usually at slightly higher cost.
A preservation tool — compare it to FDs and liquid funds.
Yields are broadly comparable to bank FDs (which currently pay a little more) and liquid funds. The right comparison is never "T-Bill vs equity" — it is T-Bill vs FD vs liquid fund. Direct T-Bills suit lump sums of ₹5 lakh+ held to maturity; liquid funds suit small, flexible amounts needing daily access. A ladder blends yield and liquidity.
At A Glance
| Metric | Value | Detail |
|---|---|---|
| Issuer | Govt of India | Via the RBI |
| Tenures | 91 / 182 / 364 days | Zero-coupon |
| Credit Risk | Minimal | Sovereign |
| Price Risk | Very low | Short tenure |
| Min Investment | ₹10,000 | RBI Retail Direct |
| 364-Day Yield | ~5.6%* | ~35 bps over repo |
| Tax | Slab STCG | No TDS, advance tax |
| Best Use | Sub-12-month goals | Not wealth creation |
Exhibit 01: After-Tax Reality of a 5.6% T-Bill
| Bracket | After-Tax Yield | Real (vs 5%) |
|---|---|---|
| ≤₹12L (rebate) | 5.6% | +0.6% |
| 15% | 4.76% | −0.24% |
| 20% | 4.48% | −0.52% |
| 30% | 3.92% | −1.08% |
*Indicative, auction-determined, February 2026. Real return assumes 5% inflation. A 30% bracket investor earns a negative real return — proof that T-Bills preserve capital rather than grow it. New-regime rebate makes income up to ₹12 lakh effectively tax-free.

The Opening
A Treasury Bill is the simplest instrument the government issues: a promise to repay a fixed sum on a fixed near date, sold today for less than that sum. There is no interest cheque, no coupon — the entire return is baked into the discount. Buy a 364-day bill of ₹1,00,000 for ₹95,000 and you collect ₹1,00,000 in a year; the ₹5,000 gap is the yield. The government uses these to bridge the timing gap between continuous spending and lumpy tax collection — its version of a working-capital loan.
"A T-Bill guarantees your rupees come back. It guarantees nothing about what those rupees will buy. At a 5.6% yield against 5% inflation and a 30% tax rate, the nominal number looks reassuring while the real return quietly turns negative."
Preservation, Not Growth
The mechanics. T-Bills are zero-coupon securities: return comes purely from buying below face value. Because they mature in under a year, there is little time for rates to move against you if you hold to maturity — interest-rate risk is very low. But sell early and you take the secondary-market price; roll the bill over year after year and your long-run return depends on the whole sequence of reinvestment yields, not just today's.
The February 2026 context. The RBI has cut the repo from 6.50% to 5.25% across the last two years, and the 364-day T-Bill yields ~5.6% — about 35 bps above repo. This late-cycle position matters: with rates likely near the bottom, an investor rolling bills over several years faces genuine reinvestment risk if the next auctions clear lower.

Part I
What a Treasury Bill Is, Why the Government Issues It, and Where It Fits
The zero-coupon mechanics of buying at a discount; how T-Bills solve the government's cash-flow timing problem; and where they belong in the money-market layer of a portfolio — above cash, below bonds, matched to sub-12-month goals.
Part I · Page 4
The Three Tenures
| T-Bill | Tenure | Yield (Feb 2026) |
|---|---|---|
| 91-day | ~3 months | ~5.3% |
| 182-day | ~6 months | ~5.4% |
| 364-day | ~1 year | ~5.6% |
All three are auctioned by the RBI on the government's behalf — 91-day bills weekly, 182 and 364-day bills on alternate Wednesdays. Because they carry no coupon, the return is simply face value minus purchase price, annualised.
Why the Government Issues Them
Solving a Timing Mismatch
Tax collections arrive in lumps (quarterly advance tax); spending is continuous (salaries on the 1st, projects, welfare). Rather than hold idle cash or take long-term loans for temporary needs, the government borrows precisely what it needs for short periods. A T-Bill is the sovereign's working-capital line — efficient, and non-disruptive to the long-term bond market.
Where T-Bills Fit
| Layer | Instrument | Role |
|---|---|---|
| Cash | Savings account | Instant access |
| Money market | T-Bills | Capital stability |
| Short bonds | 1–3 yr | Moderate return |
| Long bonds | G-Secs 5–40 yr | Duration return |
| Equity | Stocks / funds | Long-term growth |
T-Bills occupy the money-market layer: one rung above cash, safe parking for money needed within twelve months. The guiding principle is tenure-matching — a 91-day bill for next quarter's tax, a 364-day bill for a down payment a year out.
Part II
The Four Risks the Sovereign Guarantee Does Not Remove, and How You're Taxed
Why "government-backed" silences credit risk but not reinvestment, inflation, liquidity and opportunity risk; and why every rupee of T-Bill gain is Short-Term Capital Gains at your slab rate, with no TDS and a self-managed advance-tax duty.
Part II · Page 6
The Risks That Survive
Credit & Rate Risk — Low
Sovereign backing makes default minimal in rupee terms. And at under a year, held to maturity, rate moves barely touch you — your return is locked at purchase.
Reinvestment Risk — The Overlooked One
Invest ₹10 lakh in a 364-day bill at 5.6%. When it matures, if the RBI has cut, the next bill may yield 4.8%. Rolling bills over years, your effective return is the whole sequence of yields — not today's rate. Real, and sharpest late in a cutting cycle.
Inflation & Liquidity Risk
A 5.6% yield against 6% inflation is a negative real return — T-Bills preserve, not protect against inflation. And small odd-lot sales (under ₹1 lakh) on the retail secondary market can face wide bid-ask spreads; ₹5 lakh+ trades more smoothly.
Taxation (FY 2025-26)
Always STCG, Always Slab Rate
The gain (face value − purchase price) is Short-Term Capital Gains taxed at your slab rate — whether you hold two days or the full 364. A T-Bill can never be LTCG. Buy at ₹95,000, redeem at ₹1,00,000: the ₹5,000 gain is taxed at your bracket.
No TDS → Advance Tax Duty
Unlike FDs, T-Bills deduct no TDS — you receive the full amount. If your total annual tax liability exceeds ₹10,000, you must pay advance tax in four instalments (15 Jun / 15 Sep / 15 Dec / 15 Mar). Miss them and interest accrues under Sections 234B and 234C. NRIs face 20% TDS (or the lower DTAA rate).
T-Bill vs FD: Where Each Wins
| Aspect | T-Bill | Bank FD |
|---|---|---|
| Issuer | Sovereign | Bank + DICGC ₹5L |
| Yield (1yr) | ~5.6% | 6.25–7.0% |
| Rate lock | At auction | Full tenure |
| Tax admin | Advance tax | TDS auto |
Indicative Feb 2026. Both taxed at slab rate — T-Bills carry no structural tax advantage. FDs currently yield a little more; T-Bills win on sovereign safety beyond ₹5 lakh and on penalty-free (if spread-exposed) secondary liquidity.
Part III
How to Buy, T-Bills versus Liquid Funds, and the Ladder Strategy
The RBI Retail Direct route and non-competitive bidding; when a liquid fund's daily access beats a direct bill's zero expense ratio; and how a maturity ladder turns a lumpy instrument into a rolling source of yield and liquidity.
Part III · Page 8
Two Ways to Buy
| Route | Cost | Best For |
|---|---|---|
| RBI Retail Direct | Free (₹5–10 gateway) | Most investors |
| Demat / Broker | AMC ₹300–750/yr | Existing demat users |
Non-Competitive Bidding — Made Simple
On rbiretaildirect.org.in, open a free account (PAN, Aadhaar, video KYC, linked bank), add funds, and on auction day specify only the amount — ₹10,000 minimum, up to ₹2 crore per security. You accept the auction's weighted-average yield; no need to guess rates or compete with institutions. Settlement follows on Friday. Brokers like Zerodha Coin, ICICI Direct and HDFC Securities also list T-Bills, usually at slightly higher cost.
Direct T-Bill vs Liquid Fund
| Feature | Direct | Liquid Fund |
|---|---|---|
| Expense | Zero | 0.15–0.35% |
| Liquidity | To maturity | Daily |
| Min amount | ₹10,000 | ₹500 SIP |
| Reinvest | Manual | Automatic |
The T-Bill Ladder
Spread ₹10 Lakh Across Maturities
Rather than one 364-day bill, split it: ₹2.5L in a 91-day, ₹2.5L in a 182-day, ₹2.5L in a 364-day, and ₹2.5L in a liquid/overnight fund. As each bill matures, roll it into a new 364-day bill. Something is always coming due soon.
Why the Ladder Works
| Benefit | How |
|---|---|
| Liquidity | A bill matures every few months |
| Reinvest risk | Only a slice re-prices at once |
| Yield | Roll shorts into higher-yield 364s |
| Timing | Averages yields over the cycle |
Part IV
The Verdict
Safety of principal. Not safety of purchasing power.
Part IV: The Verdict · Page 10
30-Second Summary
A Treasury Bill is a zero-coupon loan to the Government of India for 91, 182 or 364 days — bought at a discount, redeemed at face value, with minimal credit risk and almost no price volatility if held to maturity. As of February 2026 the 364-day yields ~5.6%, about 35 bps over the 5.25% repo. It is the money-market layer of a portfolio: safe parking for money needed within a year, not a wealth engine.
Every gain is Short-Term Capital Gains taxed at your slab rate — a T-Bill can never be LTCG — and with no TDS you must manage advance tax yourself. Buy from ₹10,000 on RBI Retail Direct via simple non-competitive bidding. Use T-Bills for sub-12-month goals with lump sums, ideally laddered; compare them to FDs and liquid funds, never to equity. Above all, remember the after-tax, after-inflation math: for a 30% bracket investor a 5.6% yield can mean a negative real return.
"The sovereign guarantee answers one question — will my rupees come back? Yes. It says nothing about the other — what will they buy? A T-Bill is the safest way to hold money you cannot afford to lose and will soon spend. It is one of the worst ways to try to grow money you have time to invest. Confusing the two is the only real mistake."

✓ Parking for a 3–12 month goal
✓ Sovereign safety beyond ₹5L/bank
✓ A laddered short-term reserve

Three Misconceptions
What Investors Get Wrong
(1) "Government guarantee means no risk." Credit risk is minimal, but reinvestment, inflation and opportunity risks remain. (2) "5.6% is what I earn." After 30% tax it is 3.92%; after 5% inflation, negative. (3) "I can always sell instantly at fair value." Small retail odd-lots can face wide secondary-market spreads.
vs Government Bonds
Short & Flat vs Long & Volatile
T-Bills: under a year, zero-coupon, barely move in price — for parking. G-Secs: 5–40 years, semi-annual coupon, swing with rates — for income and duration positioning. Different tools for different jobs.

Key Terms & Definitions
Treasury Bill (T-Bill)
A short-term debt instrument issued by the Government of India through the RBI, in 91, 182 or 364-day tenures. It pays no coupon: you buy at a discount to face value and receive full face value at maturity, the difference being your return. The safest sub-one-year rupee instrument.
Zero-Coupon Security
A security that pays no periodic interest. The entire return comes from buying below face value and being repaid the full face value at maturity. T-Bills are the classic example — there is no coupon cheque, only the built-in discount.
Discount Yield
The annualised return implied by the gap between purchase price and face value. Pay ₹98,500 for a ₹1,00,000 bill maturing in a year and the ~₹1,500 gain represents roughly a 1.5% return over the period, annualised to the quoted yield.
Reinvestment Risk
The risk that, when a T-Bill matures, the next one you buy yields less because market rates have fallen. For investors rolling bills over multiple years, the long-run return depends on the whole sequence of reinvestment yields — most acute late in a rate-cutting cycle.
Non-Competitive Bidding
The simplified retail auction route on RBI Retail Direct: you specify only the amount you want to invest and accept the weighted-average yield the auction produces, without quoting a rate or competing with institutional bidders.
Advance Tax
Because T-Bills deduct no TDS, an investor whose total annual tax liability exceeds ₹10,000 must pay tax in four quarterly instalments (15 Jun / 15 Sep / 15 Dec / 15 Mar). Missing these triggers interest under Sections 234B and 234C.
