Government Securities & Treasury Bills: Benefits & Risks

What it is

A Retail Direct Gilt (RDG) account is a gilt account maintained with RBI that gives an eligible retail investor access to government-securities primary auctions and secondary-market transactions through the RBI Retail Direct portal. The platform's listed instruments include Government of India Treasury Bills (T-Bills), Government of India dated securities, State Development Loans and Sovereign Gold Bonds. This page focuses on T-Bills and ordinary government securities rather than treating every instrument or issue as interchangeable.

RBI describes a T-Bill as a short-term debt instrument with no periodic coupon: it is issued below its face value and redeemed at face value on maturity, so the difference between purchase price and maturity value is the return before applicable costs and taxes. Dated government securities can instead pay a fixed or floating coupon on scheduled dates and return principal at maturity. These are sovereign obligations in domestic currency, not bank deposits and not a promise that an investor will always earn a positive market return if the holding is sold early.

Availability and return mechanism

Availability

Government securities are accessible through RBI Retail Direct under RBI's framework. RBI's official calendar dated 25 September 2026 schedules Treasury Bill auctions for the October–December 2026 quarter, including an auction date of 28 October 2026, but the calendar is expressly subject to change. A scheduled auction does not mean that a particular T-Bill, dated security or other offer is currently available to you through Retail Direct.

Confirm the current RBI auction notice and the Retail Direct portal's current issue terms, bid window, settlement details and availability; do not assume that all listed schemes or offers are open at once.

How a return arises

For a T-Bill, there is no periodic interest coupon. The security is issued at a discount and the government redeems it at face value at maturity; the gross return is the difference between the maturity value and the purchase price, subject to the issue and settlement terms. For a dated government security, the return can comprise scheduled coupon payments plus principal repayment, with the price paid and the time held affecting the realised yield.

In the secondary market, price and yield move inversely: a rise in market yields can reduce the market price of an existing fixed-coupon security, while a fall can increase it. Therefore, holding to maturity and receiving the scheduled sovereign payment is a different outcome from marking the security to market or selling it before maturity. Holding to maturity can avoid crystallising that market-price loss, but it does not remove inflation, reinvestment, liquidity or other risks and does not make every investment return guaranteed in all senses.

Benefits and trade-offs

These are product characteristics to understand, not reasons you should buy this investment.

Potential benefits

Direct RBI access can combine primary-auction participation with secondary-market buying and selling, without requiring a separate securities intermediary for the RDG account itself.
In the domestic-currency sovereign-payment context, RBI describes Government securities as carrying practically no credit/default risk; this is a credit-quality benefit, not protection from market-price losses.
T-Bills have a simple maturity mechanism—discounted purchase followed by face-value redemption—while dated securities can provide scheduled coupon cash flows and principal repayment under their issue terms.
The RDG account is free to open and maintain, and government securities can add a sovereign-debt component to a diversified portfolio; applicable funding and other transaction costs still need checking.

Constraints & disadvantages

A sale before maturity can realise a mark-to-market loss when interest rates rise or the security's market price moves against the holder, even though the sovereign payment at maturity remains a separate contractual outcome.
Secondary-market access does not guarantee liquidity, a buyer, a chosen price or low spreads; an urgent sale can occur at an adverse price.
Retail Direct primary participation is non-competitive: an individual does not enter a chosen bid price, and allotment pricing is based on the weighted average price from the auction. The amount initially funded can include a refundable markup to cover price uncertainty.
T-Bills do not pay periodic coupons, so cash flow arrives at maturity and proceeds may have to be reinvested at an unknown future yield. Payment-gateway charges, KYC effort and tax obligations can also reduce the effective outcome.

Eligibility and access

RBI's Retail Direct FAQ says the account is for retail investors who are individuals (natural persons). The stated onboarding requirements are a rupee savings bank account maintained in India, a PAN issued by the Income Tax Department, an officially valid KYC document, a valid email address and a registered mobile number. Non-resident retail investors who are eligible to invest in Government Securities under FEMA may also be eligible.

The account may be opened singly or jointly with another retail investor meeting the eligibility criteria. KYC and portal terms can change, so the current RBI requirements should be checked before registration.

Liquidity and time commitment

RBI's Retail Direct framework does not state a general lock-in: a holder can place a sell order in the secondary-market portal, but must already hold the security. Retail Direct provides access to NDS-OM secondary-market trading, including the odd-lot/RFQ routes described by RBI. That access is not a promise of an instant sale, a buyer at a chosen price or a narrow spread for every security.

RBI's primer defines liquidity risk as difficulty finding buyers or having to sell at a distressed price, and notes that a security can become less liquid as its remaining tenor shortens or trading activity/reissuance declines. A person who may need the money before maturity should not treat the maturity date as a practical liquidity guarantee.

Risks to understand

Market and mark-to-market risk: changes in interest rates can move bond prices; selling or valuing before maturity can show a loss even when the security is ultimately redeemed at its scheduled value.
Liquidity risk: a particular issue may have limited trading activity or wider spreads, and a forced sale may be at a distressed price or may take time.
Reinvestment risk: coupon or maturity proceeds may not be reinvestable at the yield available when the original security was bought; for a T-Bill this matters when the maturity proceeds are rolled into another instrument.
Inflation and purchasing-power risk: a nominal sovereign payment can buy less if prices rise faster than the investment's realised return; RBI's credit-risk description does not remove this risk.
Primary-auction pricing and allocation risk: non-competitive bidders cannot choose the price, allotment may be partial, and the initial funding amount can differ from the final allotment amount with a later refund of excess markup under the stated process.
Operational and settlement risk: bids need to be funded through the linked bank/payment route within the applicable window, and securities and sale proceeds are credited according to settlement timelines and portal terms.
Residual legal, sovereign and policy risk should not be described as literally zero merely because RBI calls domestic-currency G-Secs credit-risk-free or practically default-free; the statement addresses credit/default risk and does not guarantee market value, liquidity, inflation-adjusted returns or uninterrupted access.

Costs and tax considerations

RBI says opening and maintaining the RDG account is free, and no fee is charged by RBI or the aggregator for submitting a primary-auction bid. Applicable payment-gateway charges for funding purchases are borne by the investor. RBI also notes that rebalancing or selling can involve transaction and other costs; current portal and settlement terms should be checked for any applicable charge.

RBI's Retail Direct FAQ and primer do not provide a current income-tax rate or complete tax guidance for T-Bill discount income, coupon income, capital gains or secondary-market sales. Tax treatment can depend on the instrument, transaction, holding period and the law applicable at the time, so readers should consult the current Income-tax rules or a qualified tax professional rather than assume tax-free or fixed-rate treatment.

Tax treatment depends on current law, the instrument and the investor’s circumstances. This is not tax advice and does not assume that a tax benefit applies to every reader.

Before relying on it

Read the latest official scheme or issue document. A general framework is not proof that a specific offer is open.
Confirm the eligibility, payment mechanism, charges, lock-in and early-exit conditions for the exact product and channel.
Separate a stated coupon or notified interest rate from total return, after-tax outcome and inflation-adjusted purchasing power.
Verify the issuer and intermediary, preserve records, and use current official tax guidance where it applies.
Consider when the money may be needed and what a loss would mean. This explanation does not assess your personal suitability.
