One of the safest short-term investment options in India is Treasury Bills or T-Bills. These are issued by the Government of India through the Reserve Bank of India (RBI) to meet the short-term borrowing requirements of the government and provide investors a safe avenue to invest their surplus funds.
RBI T-Bills are different from other fixed income instruments as they do not pay periodic interest. Instead, they are sold at a discount and redeemed at par at maturity, the difference being the profit to the investor.
If you are wondering how to buy Treasury Bills in India, this guide explains the available investment routes, the eligibility criteria and the steps involved in investing.
Government-backed securities, such as the Treasury Bills, are now within the reach of retail investors, who can buy them through a variety of investment routes in India. You can invest in T-Bills investments either directly with the RBI or through market intermediaries, whichever is convenient to you.
Overview of available investment routes
As a retail investor, you can invest in Treasury Bills through several routes:
Each route provides access to government securities India, although the investment process may differ slightly.
Eligibility for retail investors
Treasury Bills are not limited to banks and financial institutions. Individual retail investors are also fully eligible to invest in them. They can do it by participating in RBI auctions through the non-competitive bidding facility or by purchasing them in the secondary market. The eligibility criteria for the same is:
A. Individuals (natural persons), i.e. retail investors. To open an account, you will need to:
B. Non-Resident retail investors eligible to invest in Government Securities under Foreign Exchange Management Act, 1999.
Minimum investment requirements
Minimum investment amount in Government of India Treasury Bills (T-Bills) is INR 10,000 (as on Nov 12, 2021). Thereafter, the investment is made in multiples. However, investors should always check the details of the relevant issue before submitting their bids, as the terms could be different.
There are different methods to complete a treasury bill purchase, depending on how you wish to invest.
1. RBI Retail Direct
RBI Retail Direct enables individual investors to purchase Treasury Bills directly by participating in RBI non-competitive primary auctions through an online platform. All you have to do is open a free RBI Retail Direct account, complete KYC, bid in Treasury Bill auctions and receive maturity proceeds directly in your linked bank account.
2. Secondary market
Treasury Bills can also be purchased from the secondary market through registered brokers and recognised stock exchanges. This allows investors to buy securities that have already been issued instead of waiting for a fresh auction.
3. Grip Invest
Investors may also use platforms such as Grip that provide access to fixed-income investment opportunities. Before investing through any platform, it is important to understand the investment process, applicable charges and the products being offered.
The requirement depends on how you invest.
When investing through RBI Retail Direct, Treasury Bills are held in the Retail Direct Gilt (RDG) account maintained by RBI, so a separate Demat account is generally not required.
However, investors purchasing Treasury Bills through stock exchanges may need a Demat and trading account, depending on the broker and investment platform they use.
Before investing, investors should verify the account requirements applicable to their chosen route.
Opening an account under RBI Retail Direct allows eligible retail investors to participate directly in Treasury Bill auctions.
1. Open an RBI Retail Direct account
Start by signing up for an RBI Retail Direct account through the online registration process. This account is the entry point to buy Treasury Bills India directly in the RBI.
2. Complete KYC
Once the account is created, the Know Your Customer (KYC) formalities have to be completed as required during the registration process. The account will be activated after successful verification.
3. Participate in auctions
When your account is activated, you may use it to apply for Treasury Bill auctions by choosing the issue you want to bid on, and then submitting your application using the non-competitive bid process available to retail investors.
4. Receive allotment
After the auction ends, successful bidders will have the Treasury Bills they won credited to their Retail Direct account according to the auction results.
5. Hold till maturity or sell
After allotment, investors can either hold the Treasury Bills until maturity and receive the face value or sell them in the secondary market before maturity if they require liquidity.

Apart from participating in primary auctions, investors can also purchase Treasury Bills after they have been issued. The secondary market enables investors to buy existing Treasury Bills through recognised stock exchanges and brokers.
Current holders often sell their holdings before maturity. However, as these transactions occur after the original issuance, the market price may not be the same as the face value. This provides investors with flexibility if they miss an auction or don't want to wait for a new issue.
Investors can purchase Treasury Bills either during RBI auctions or after issuance.
| Primary Market | Secondary Market |
| Purchase directly during RBI auction | Purchase existing Treasury Bills from other investors |
| Price determined through auction | Price depends on market demand and supply |
| Available only on auction dates | Available whenever market liquidity exists |
| Suitable for planned investments | Suitable when immediate investment is preferred |
Both methods provide access to Government securities, but investors should understand the pricing differences before investing.
Retail investors can choose different methods to buy Treasury Bills depending on their investment preferences.
| Investment Route | Suitable For | Key Features | Minimum Investment |
| RBI Retail Direct | Investors who want to buy directly from RBI without intermediaries | Direct participation in primary auctions, no intermediary fees, holds securities in Retail Direct account | INR 10,000 (in multiples) |
| Stock Exchange / Broker | Investors who already have a trading account and prefer secondary market purchases | Buy existing T-Bills, flexible maturity options, requires demat and trading account | Market-dependent (typically INR 10,000+) |
