Introduction to Treasury Bills

Treasury bills, often referred to as T-bills, are a crucial component of the money market, issued by the Government of India as short-term promissory notes. These instruments are primarily used to bridge short-term funding needs and play a pivotal role in reducing the country’s fiscal deficit. By offering a guaranteed repayment at a later date, treasury bills provide a secure investment option for individuals and financial institutions alike.

Treasury Bills: Key Features and Benefits

Treasury bills are unique in their structure, primarily because they are short-term instruments with a maximum tenure of 364 days. Unlike traditional bonds, T-bills do not carry an interest rate, also known as a coupon rate. Instead, they are issued at a discount to their face value, allowing investors to earn a profit upon maturity.

For example, if you purchase a 91-day treasury bill with a face value of Rs. 120 at a discounted price of Rs. 118.40, you will receive the full Rs. 120 upon maturity, netting a profit of Rs. 1.60. This method of investment offers a low-risk opportunity to earn returns over a short period.

Why the Government Issues Treasury Bills

The government utilizes treasury bills to meet immediate financial obligations that exceed its annual revenue. By issuing T-bills, the government can efficiently manage its short-term debt and regulate the overall money supply in the economy.

The Reserve Bank of India (RBI) also plays a critical role in issuing treasury bills as part of its open market operations (OMO). During periods of high inflation, the RBI may issue high-value T-bills to reduce the money supply, thereby helping to control inflation. Conversely, during economic slowdowns, the RBI may reduce the circulation of T-bills to encourage investment in other sectors, such as the stock market, boosting overall economic productivity.

Types of Treasury Bills

Treasury bills are categorized based on their tenure. The most common types include:

• 91-day Treasury Bills: Short-term instruments maturing in 91 days.
• 182-day Treasury Bills: Medium-term instruments with a 182-day tenure.
• 364-day Treasury Bills: Longest-tenure T-bills, maturing in 364 days.

Although the tenure of these instruments varies, the face value and discount rates are subject to change based on the RBI’s monetary policy and market demand.

Features of Treasury Bills

Investing in treasury bills requires a minimum investment of Rs. 25,000, with increments in multiples of Rs. 25,000 for larger investments. As zero-coupon securities, T-bills do not offer interest. Instead, investors earn by purchasing these bills at a discount and redeeming them at face value upon maturity.

The RBI auctions treasury bills weekly, with bids placed on major stock exchanges. Investors can acquire T-bills through depository participant commercial banks or registered primary dealers (PDs), with transactions typically following a T+1 settlement process.

Yield Rate on Treasury Bills

The yield on a treasury bill can be calculated using the following formula:

Y = (100 – P) / P × 365 / D × 100

Where:

• Y = Return percentage
• P = Discounted purchase price
• D = Tenure of the bill

For instance, if a 91-day T-bill is issued at Rs. 98 and its face value is Rs. 100, the yield would be calculated as follows:

Yield = (100 – 98) / 98 × 365 / 91 × 100 = 8.19%

This calculation helps investors determine the potential return on their investment.

Advantages of Investing in Treasury Bills

Treasury bills are a popular investment choice due to their backing by the central government, offering unparalleled security. Even during economic downturns, T-bills remain a reliable investment option, as the government guarantees repayment.

With a maximum maturity of 364 days, T-bills are ideal for investors seeking short-term gains through secure investments. Additionally, T-bills can be resold in the secondary market, providing liquidity in case of emergencies.

The RBI’s weekly auctions allow retail and small-scale investors to participate without needing to quote yield rates or prices, making T-bills accessible to a broader audience and increasing capital market flows.

Limitations of Treasury Bills

Despite their advantages, treasury bills have some limitations. The primary drawback is their relatively low returns compared to other investment options, such as stocks. Since T-bills are zero-coupon securities, their returns remain constant regardless of market conditions. This contrasts with the stock market, where returns can fluctuate significantly based on market performance.

Tax Implications

Earnings from treasury bills are subject to short-term capital gains (STCG) tax, with the applicable rate determined by the investor’s income tax slab. However, one key advantage is that retail investors are not required to pay tax deducted at source (TDS) upon redemption, simplifying the tax process for those not in the taxable income bracket.

Conclusion

Treasury bills offer a secure and reliable investment option for those seeking short-term gains. Backed by the Government of India and issued by the RBI, these instruments provide a low-risk way to invest in the money market. While they may offer lower returns than other investments, their guaranteed repayment and liquidity make them an attractive choice for conservative investors.
