Summary
The treasury bill is a security that earns returns from the difference between the purchase price and face value based on the spread between the cost of buying and the value at maturity, which is paid at the end of the period. Such securities have a key role in financing government spending and maintaining liquidity.
Introduction
Treasury bills sit at the intersection of two needs: the government’s requirement to bridge short-term funding gaps and investors’ need for a risk-free place to park surplus cash. Issued by the Reserve Bank of India on behalf of the government, T-bills carry no credit risk, have no periodic interest payments, and involve no lock-in penalty. The return is simply the difference between the purchase price and the amount received at maturity.
This article explains how that mechanism works, the three tenors available, how to participate in auctions, and what to watch out for before investing.
Key Takeaways
- These securities are sold at a discount, and when redeemed, they pay the face value.
- There are three maturities of T-bills that include 91 days, 182 days, and 364 days.
- The creditworthiness of these securities is assured by the government, and therefore, there is no default risk for investors.
- Individuals can purchase T-bills without intermediaries by using the RBI Retail Direct portal.
What Are Treasury Bills?
The definition of treasury bills is that they refer to a type of debt security issued by the central government used in meeting its immediate funding requirements. Treasury bills do not earn any form of interest. The securities are sold at a discounted price and repaid at face value once maturity occurs. The important characteristics of treasury bills include their being backed by the sovereign government, having no interest, being short-term, and being highly liquid.
For example, a 91-day T-bill with a face value of ₹100,000 purchased at ₹98,200 returns ₹100,000 at maturity. ₹1,800 is the gain – there are no coupon payments or complications.
Treasury Bill Tenors in India
Treasury bills in India are issued in three primary tenures: 91 days, 182 days, and 364 days. A 14-day T-bill also exists and was introduced in 1997, but it is issued infrequently and is not available to retail investors. As a result, retail participation is effectively limited to these three standard tenures set by the Reserve Bank of India.
- 91-day T-bills: The most liquid variety that is commonly used for short-term cash management.
- 182-day T-bills: Provide slightly higher returns than the above variety but require a longer period.
- 364-day T-bills: Provide the maximum returns since funds will be tied up for an entire year.
The 91-day T-bill is auctioned every week. The 182-day and 364-day T-bills are typically auctioned biweekly, though the Reserve Bank of India publishes a quarterly auction calendar that can adjust the frequency. In some recent quarters, all three tenors have been auctioned weekly. Cut-off yields are determined by the auction outcome each time.
How Do Treasury Bills Work and What is Their Trade Process?
Understanding how to buy treasury bills begins with the RBI auction process. Investors submit competitive bids specifying quantity and yield, or non-competitive bids that accept the auction-determined yield. Bidding proceeds from the highest price downward until the notified amount is fully subscribed.
Knowing how to buy treasury bills in India specifically, retail investors have three routes: the RBI Retail Direct portal, a CSGL account with a bank, or a registered broker. The Retail Direct portal is the most straightforward option, like direct, no-intermediary, with non-competitive bidding.
Exploring the Secondary Market for Treasury Bills
After their issuance, T-bills can be traded in the secondary market prior to maturity, which offers an edge over fixed deposits, where premature withdrawal usually results in penalties. The price of T-bills moves inversely with the level of interest rate; hence, if interest rates increase, the price of T-bills will decrease.
Remark: It should be noted that although the secondary market is quite liquid for institutional players, this may not be the case for individual investors.
Understanding the Maturity Process of Treasury Bills
At maturity, nothing is required to be done since the face value will automatically be credited to your bank account. Because T-bills are dematerialized securities, the entire process is completely automated and requires no paperwork.
How to Choose a Broker or an Easy Investment Platform?
The right choice on how to purchase T-bills in India depends on your setup and how actively you plan to invest. The RBI Retail Direct portal suits first-time investors who want a no-cost, no-intermediary starting point with a simple KYC process. A CSGL account through a bank suits those who prefer their T-bill holdings to remain within their existing banking relationship.
A registered broker suits investors who already hold equity or mutual funds and want T-bills visible on the same dashboard, along with consolidated tax reporting.
All three routes provide access to the same primary auctions and the NDS OM secondary market. The difference lies in convenience, interface, and whether you want a unified portfolio view.
The Risks and Returns of Investing in Treasury Bills
T-bills are among the most risk-free securities, yet three particular risks need to be considered when evaluating their performance in practice.
- Reinvestment risk: Frequent reinvestment is required because the tenure is relatively short, which may come at reduced rates.
- Liquidity risk: The secondary market might not provide sufficient liquidity for individual investors.
- Inflation risk: If inflation unexpectedly spikes, then the actual rate of return could become negative despite a stable nominal return.
Understanding the Returns
Returns would be contingent upon the yield cut-off in the auction. Typically, yields of 91-day T-bills in India range from 4 percent to 7.5 percent and move in line with the repo rate of the RBI. Yield on the 364-day bill is usually slightly higher. The complete yield is earned at maturity only.
Treasury Bills vs. Other Investment Options
Comparison with different short-term instruments will help understand where T-bills fit in when included in an investor’s overall portfolio.
- vs. Savings account: Offers more yield with similar risk.
- vs. Fixed deposit: More flexible because there is no loss on exiting early as opposed to an FD. Also, offers liquidity in the secondary market. Sometimes, FDs have better yields than T-bills.
- vs. Liquid mutual funds: Less volatile, returns are market-linked and reflected through NAV movements.
Why Are Treasury Bills Crucial for a Government’s Fiscal System?
The inflow of tax revenue occurs periodically, while expenditure is constant. The T-bill is helpful in that it helps the government borrow over shorter periods and pay back faster without accruing huge amounts in debt charges.
If there is more spending than income, then the difference becomes the fiscal deficit. Treasury bills are one of the methods used to finance such a deficit in the short term. Unlike other bonds, treasury bills can be bought and sold in just a few weeks, allowing the government some flexibility.
- Facilitating Monetary Policy Actions
The Reserve Bank of India uses T-bills as an active tool to manage liquidity in the banking system. When it wants to absorb excess liquidity, it conducts open market operations by selling government securities, including T-bills, to banks, which pulls money out of circulation. When it needs to inject liquidity, it buys these securities back.
T-bill yields also act as a real-time signal of short-term liquidity conditions. When yields rise above the repo rate, it points to tight liquidity. When they fall below it, the system has surplus liquidity. This makes T-bill yields an important indicator for the RBI while calibrating monetary policy between scheduled policy reviews.
How to Determine Which Treasury Bill Tenure Is Right for You?
The correct tenure depends on liquidity requirements and interest rate expectations. If liquidity is required in the next three months, the three-month bill is ideal. In the case of six months, the 182-day bill provides more returns. For obtaining a riskless return for a year, the 364-day bill should be considered.
When there is an upward trend in the interest rate, shorter tenure bills should be selected due to their earlier maturity date and higher interest rates. However, during the downward trend in interest rates, one should opt for the 364-day bill early.
Conclusion
The Treasury bills are debt securities that have the backing of the sovereign and are classified into three categories based on their tenure: 91 days, 182 days, and 364 days. The discount-to-face-value concept underlies the Treasury bills.
Determine an investment horizon for yourself, and ensure that you invest through a credible and RBI-approved platform. Keep an eye on auctions and compare the yields with the repo rate. You might consider laddering across different maturities. Through a disciplined approach, Treasury bills can make for a strong foundation for any portfolio.
