Bond markets offer a variety of instruments that can potentially deliver better growth than traditional FDs or high-yield savings accounts. If you are looking for an investment instrument that offers capital protection along with meaningful growth, deep discount bonds can be a suitable choice for you.
In this guide, we’ll explore how the deep discounted bond structure works, why it appeals to conservative investors seeking growth, whether you should invest in these bonds, and much more. Let’s dive in.
What are Deep Discount Bonds?
The term “Deep Discount Bond” or DDB means that any potential buyer can invest in these bonds at a discount. These bonds are sold at a discount of 20% or more than their par value.
Deep discount bonds are typically issued by companies or institutions with lower creditworthiness or limited repayment capacity, or companies looking to fund projects with unpredictable cash flows.
Unlike regular bonds, deep discount bonds pay investors with little to no periodic interest. Instead, the issuer pays the entire interest payment plus the principal at the bond’s maturity.
Due to lack of interest payment feature, deep discount bonds and zero-coupon bonds may appear similar at first glance but zero-coupon bonds are typically issued by entities with high credit ratings, including governments and financially stable corporations. One such example of zero-coupon bonds is Treasury Bills (T-Bills) issued by the Reserve Bank of India.
On the other hand, one recent example of deep discount bonds includes REC (Rural Electrification Corporation), which received government approval in June 2025 to raise up to ₹50 billion through deep discount bonds for the second time.
While the definition and examples give us a clear picture of what deep discount bonds are, the real question is, how do they actually work in practice? Let’s take a look.
How do Deep Discount Bonds Work?
The structure of deep discount bonds is designed to make them lucrative for investors looking to park their money for the long-term. The deep discount bonds or DDBs are issued at a steep discount of 20% or more on their par value. This makes the potential returns on these bonds higher if held until maturity.
Generally, issuers looking to raise funds for a project with unpredictable or irregular income streams issue these bonds. These issuers often have lower creditworthiness and hence offer higher discounts to compensate for the elevated risk. Note, the higher the risk associated with DDBs, the greater the discount offered.
In the past, these bonds were issued and sold at prices as low as a few thousand rupees, while their maturity value was set at several lakhs. For example, the Industrial Development Bank of India (IDBI) issued deep discount bonds in 1992. These bonds were offered at ₹2,700 for a face value of ₹1,00,000. Meaning, investors who bought these bonds at ₹2,700, received ₹1,00,000 after 25 years at maturity.
This feature of the deep discount bond makes it appealing to investors who are willing to take risk and want to invest for longer term. Let’s look at some other important features.
Features and Characteristics of Deep Discount Bonds
Here are five features and characteristics that make the deep discount bonds unique.
- Issued at a Heavy Discount: These bonds are sold at 20% or more below their face value.
- Lump Sum Payout at Maturity: Instead of regular interest payments, investors receive both the principal and accumulated returns in a single payout at maturity.
- Long-term Investment Horizon: Typically issued with maturities ranging up to 30 years, with a minimum tenure of around 5 years.
- Risk-return Trade-off: Issued by entities with lower credit ratings, they carry higher risk, which is offset by deeper discounts and potentially higher yield-to-maturity (YTM).
- Ideal for Projects with Irregular Cash Flows: Issuers prefer these bonds when project income streams are uncertain, as they eliminate the burden of frequent coupon payments.
While these features define the structure of deep discount bonds, their true value for investors also depends on how they are taxed. Let’s look at the taxation rules that apply to different types of DDBs.
Taxation of Deep Discount Bonds
Taxation on deep discount bonds can be classified into three types –
- Listed Deep Discount Bonds (Zero-Interest)
Entire capital gain (difference between purchase price and redemption value) is treated as long-term capital gain if held over 12 months, taxed at 12.5% with zero indexation benefits on investments made after 01/04/2023.
- Unlisted Deep Discount Bonds
With effect from 01/04/2023, the capital gains on sale of unlisted bonds or debentures are always considered short-term, irrespective of the holding period.
- Interest-Bearing Deep Discount Bonds
Interest portions received are taxed as “income from other sources” at the investor’s marginal slab rate in the year received, while capital gains follow the listed/unlisted classification rules above.
Understanding taxation is crucial because it directly impacts net returns. Once taxation is clear, the next logical step is to assess the benefits these bonds can bring to long-term investors.
Benefits of Investing in Deep Discount Bonds
Investing in deep discount bonds offer multiple advantages for investors. Here are four key benefits of investing in deep discount bonds.
- Capital Appreciation: Since these bonds are purchased well below their face value, investors can enjoy significant capital gains when they are redeemed at full value upon maturity.
- Affordability: One of the key advantages of deep discount bonds is their low entry point. Investors can start with a small initial investment and, in many cases, avoid additional costs like brokerage or underwriting fees.
- Fixed Returns Over Time: DDBs are ideal for investors seeking predictable and stable returns. Once purchased, the maturity value is predetermined, ensuring clarity on the exact payout at the end of the tenure.
- Best Suited for Long-Term Investors: With maturities often ranging between 5 and 30 years, DDBs are perfect for individuals with long-term financial goals such as retirement planning, child education, or wealth creation.
- Better Liquidity Options: While these bonds are primarily designed for long-term holding, many issuances are listed on exchanges, allowing investors to sell them in the secondary market before maturity if required.
Knowing the benefits of these bonds is just covering one side of the coin, the other side is all about the risks associated with these bonds. Let us discuss all the key risks associated with deep discount bonds.
Risks Involved with Deep Discount Bonds
Risks of Deep Discount Bonds
- Credit Risk: Issuers often have lower credit ratings, which increases the chance of default on redemption.
- Tax Risk: The capital gains applied on these bonds can lower your overall returns.
- Interest payments: While a few deep discount bonds may offer occasional interest payouts, most do not provide pay anything until maturity.
Examples of Deep Discount Bonds in India
- Rural Electrification Corporation (REC): Under the government mandate, REC issues zero-coupon bonds that function similarly to deep discount bonds. Sold at substantial discounts, these bonds mature at full face value, combining sovereign‐linked safety with predictable returns for long‐term investors.
- PSU Deep Discount Issues via RBI Auctions: From time to time, the Reserve Bank of India conducts auctions of PSU deep discount bonds, such as bonds from Indian Railway Finance Corporation (IRFC) and Power Finance Corporation (PFC), where participating retail and institutional investors can buy at discounts ranging from 20–35% to face value, receiving the full redemption amount at maturity.
- State-backed Development Finance Bonds: Bonds issued by agencies like Small Industries Development Bank of India (SIDBI) occasionally include deep discount tranches tailored to infrastructure and project financing. These issues attract conservative investors seeking higher yields than regular PSU bonds without exposure to equity volatility.
Who Should Invest in Deep Discount Bonds?
Deep discount bonds are best suited for investors who are conservative in nature. You should invest in these bonds if you:
- Looking to invest for a long time (5 to 30 years)
- Seek a certain lump-sum payment rather than recurring income
- Want higher growth compared to a high yield savings account and a traditional FD.
Conclusion
Deep discount bonds aren’t for everyone. They suit investors who can lock in money for years without expecting regular income. But if you are aligning them with long-term goals like retirement, buying a house, or funding education, they will work like a disciplined savings plan that grows quietly in the background. The key is to match the bond’s maturity with your financial milestone.
