T-bills Investment in India: A Complete Guide from Zero to Hero

Introduction: What Are T-bills and Why Should You Care?

In an environment of volatile stock markets and uncertain returns, many investors are seeking safe, short-term instruments to park their money. Enter T-bills investment—a secure, government-backed option that offers fixed returns over short periods.

T-bills, or Treasury Bills, are short-term debt instruments issued by the Government of India through the Reserve Bank of India (RBI). They offer a low-risk avenue for investors looking to preserve capital and earn predictable returns. If you’re exploring options beyond traditional fixed deposits or looking for a safe place to park your surplus funds, this guide will walk you through T-bills investment step by step.

What Are Treasury Bills (T-bills)?

Treasury Bills are zero-coupon securities issued at a discount and redeemed at face value on maturity. These are short-term money market instruments, designed to help the government manage its short-term financing needs.

T-bills come in three main tenors:

• 91 days
• 182 days
• 364 days

For example, if you buy a 91-day T-bill with a face value of ₹100 at ₹98, you will earn ₹2 on maturity—your return. This is known as discounted issuance, a core characteristic of T-bills investment.

How Does T-bills Investment Work?

Let’s break down the process of T-bills investment:

1. Issuance and Auctions by RBI

T-bills are issued by the RBI on behalf of the Government of India. The issuance happens through a weekly auction mechanism, where participants bid to purchase a specific amount of T-bills.

There are two types of bidding:

• Competitive Bidding (for institutional investors like banks, PDs)
• Non-Competitive Bidding (for individuals and retail investors)

Retail investors can invest via the non-competitive route, where they are allotted T-bills at the weighted average yield decided in the competitive bidding.

2. Discounted Purchase, Face Value Redemption

T-bills are issued at a discount and redeemed at face value. This means:

• No interest is paid during the tenure.
• The return is the difference between the issue price and face value.

Example:
You buy a 182-day T-bill with a face value of ₹100 at ₹95.
At maturity, you receive ₹100. Your effective return is ₹5.

Benefits of T-bills Investment

Safety

T-bills are backed by the Government of India, which makes them virtually risk-free. They carry zero credit risk, unlike corporate bonds or some mutual funds.

Liquidity

T-bills are highly liquid instruments. They can be sold in the secondary market before maturity if needed, offering flexibility to investors.

Short-Term Tenure

With maximum maturity of 364 days, T-bills are perfect for short-term investment horizons, ideal for parking idle cash or planning for near-term financial goals.

Benchmark Role

T-bill yields act as benchmarks for short-term interest rates. Their movements reflect broader liquidity conditions and monetary policy stance in the country.

Portfolio Diversification

Adding T-bills to your portfolio helps diversify risk, especially during market volatility. They serve as a hedge against equity market downturns.

Who Can Invest in T-bills?

The investor base for T-bills is diverse and growing. It includes:

• Banks
• Mutual Funds
• Insurance Companies
• Pension Funds
• Corporates
• Retail Investors

With platforms like RBI Retail Direct, even individual investors can now participate directly in government securities, including T-bills.

How to Invest in T-bills in India?

There are three popular ways to invest in T-bills:

1. RBI Retail Direct Platform

• Free registration for individuals
• Direct access to non-competitive bidding in auctions
• Simple process to buy T-bills and hold them in a Gilt account

2. Stock Exchanges (NSE/BSE)

• Through your demat account
• Offered as listed securities
• Easier for investors familiar with equity trading

3. Mutual Funds or Debt Funds

• Indirect exposure through liquid funds or short-duration debt funds
• These funds invest in T-bills and other short-term securities
• Offers professional management and liquidity

How Are T-bill Returns Calculated?

T-bills do not offer fixed coupon rates like bonds. Instead, returns depend on the discounted price at which they are issued.

Example:

• Purchase Price = ₹97
• Face Value = ₹100
• Days to Maturity = 91
• Yield ≈ 12.37% annualized

This yield varies with auction demand and prevailing market interest rates.

Are T-bills Taxable?

Yes, the gains on T-bills are taxable as short-term capital gains (STCG). Since T-bills mature within a year, you must add the profit (the difference between the face value and purchase price) to your income and pay tax according to your income tax slab.

However, because they are zero-coupon instruments, the issuer doesn’t deduct any TDS (Tax Deducted at Source) at maturity.

Risks and Considerations

Although T-bills are among the safest instruments, investors should still be aware of the following:

• Reinvestment Risk: If interest rates fall, reinvesting the proceeds may yield lower returns.
• Lower Returns vs Equity: Being low-risk instruments, returns are also moderate compared to equities or corporate bonds.
• Taxation: Gains are fully taxable as per slab—no indexation benefit available.

Bank FD	Low	Medium	7 days – 10 yrs	Moderate
