Treasury Bills vs Fixed Deposits: Key Differences Every Indian Investor Should Know

Why Indian Investors Need to Understand These Two Popular Investment Options

When it comes to safe investment options in India, treasury bills and fixed deposits dominate the conversation among urban and semi-urban households. Recent RBI data shows that bank fixed deposits totalled over ₹180 lakh crore as of March 2025, whilst treasury bill investments have surged with nearly 5 lakh registered investors in two years.

Treasury bills are issued by the Reserve Bank of India on behalf of the Government of India, making them virtually risk-free investments. Meanwhile, fixed deposits continue to attract millions of Indians seeking guaranteed returns with flexible tenure options.

Understanding the key differences between these two investment vehicles becomes crucial for making informed financial decisions that align with your specific goals and time horizon.

What Are Treasury Bills, and How Do They Work?

Treasury bills represent short-term debt instruments that the Government of India issues through RBI auctions. These zero-coupon securities are sold at a discount to their face value and redeemed at full value upon maturity. The treasury bills’ maturity period is strictly limited to three options: 91 days, 182 days, or 364 days, making them purely short-term investment vehicles.

The treasury bill investment mechanism works differently from traditional interest-bearing securities. Instead of earning periodic interest, you profit from the difference between the discounted purchase price and the face value at maturity. For instance, if you buy a 91-day treasury bill with a face value of ₹1 lakh for ₹98,200, your return is ₹1,800 over three months.

Understanding Fixed Deposits Structure and Features

Fixed deposits represent time deposits where you park a lump sum with banks, NBFCs, or financial institutions for a predetermined period at a fixed interest rate. Unlike treasury bills, fixed deposits offer remarkable flexibility in tenure, ranging from 7 days to 10 years, catering to both short-term and long-term financial planning needs.

Fixed deposits by Airtel Finance provide competitive interest rates starting from attractive percentages, with the convenience of 100% digital processing and instant account opening. The minimum investment typically starts from ₹1,000, making it accessible to a broader range of investors compared to treasury bills.

Fixed deposits offer multiple interest payout options:

1. Cumulative Deposits: Interest compounds and pays at maturity.
2. Non-Cumulative Deposits: Regular interest payouts (monthly/quarterly).
3. Tax-saving Deposits: 5-year lock-in with Section 80C benefits.
4. Senior Citizen Deposits: Higher interest rates for individuals above 60 years.

Key Differences: Treasury Bills vs Fixed Deposits

Returns Analysis: Which Offers Better Yields?

Treasury bill rates fluctuate based on market conditions, monetary policy, and demand-supply dynamics in government securities markets. Currently, treasury bill interest rates hover around 6.5% to 7.5% annually, depending on the specific maturity period and prevailing market conditions.

Fixed deposit interest rates generally range from 6% to 8% per annum, with longer tenures commanding higher rates. Senior citizens typically receive an additional 0.25% to 0.50% above standard rates.

Liquidity and Accessibility Factors

Treasury bills excel in liquidity provisions, allowing investors to sell their holdings anytime before maturity through the secondary market. This flexibility makes them ideal for parking surplus funds that might be needed on short notice. However, secondary market prices can fluctuate based on interest rate movements, potentially resulting in capital gains or losses.

Fixed deposits traditionally required investors to complete the full tenure or face penalty charges ranging from a 0.5% to 1% reduction in interest rates. However, modern offerings like those from financial institutions provide more flexible terms. Some investors also explore loans against FD options when they need funds without breaking their deposits.

The accessibility factor also differs significantly:

• Treasury bills require Demat accounts and familiarity with government securities platforms.
• Fixed deposits can be opened instantly through digital platforms with basic KYC requirements.
• Fixed deposit documents typically include just PAN and Aadhaar for quick processing.

Tax Implications and Investment Strategy

Treasury bills offer a tax advantage, as no TDS is deducted at the source, though the gains are taxable as per your income slab. This can be beneficial for investors in lower tax brackets or those managing their tax planning strategically throughout the financial year.

Fixed deposits attract TDS when annual interest exceeds ₹40,000 for general investors and ₹50,000 for senior citizens. However, tax-saving fixed deposits provide Section 80C deduction benefits up to ₹1.5 lakh, which treasury bills cannot offer.

Investment Strategy Framework:

1. Emergency Fund Parking: Choose treasury bills for 3-6 month surplus funds.
2. Regular Income Needs: Opt for non-cumulative fixed deposits.
3. Tax Planning: Consider tax-saving FDs for Section 80C benefits.
4. Wealth Preservation: Treasury bills for absolute safety with short-term goals.

Making the Right Choice for Your Portfolio

Your choice between treasury bills and fixed deposits should align with your specific financial goals, time horizon, and liquidity requirements. Treasury bills suit investors seeking maximum safety with short-term parking needs, whilst fixed deposits work better for predictable income generation and longer-term savings goals.

For those seeking the convenience of digital fixed deposit management with competitive rates, exploring established financial platforms like Airtel Finance can provide the perfect balance of safety, returns, and accessibility that modern Indian investors demand.
