Introduction

The term Original Issue Discount (OID) refers to a financial instrument that is issued at a price lower than its face value (par value). Investors earn returns through the difference between the discounted issue price and the full face value they receive at maturity. This concept is commonly associated with bonds, Treasury Bills (T-Bills), and other fixed-income securities in India.

OID is widely used in the Indian debt market, especially in government securities and corporate bonds. Instruments like Treasury Bills, Zero-Coupon Bonds, and Deep Discount Bonds operate on the principle of Original Issue Discount, making them attractive for investors looking for a fixed-income investment with predictable returns.

In this article, we will explore the meaning, working, taxation, and significance of Original Issue Discount in the Indian financial market.

What Is Original Issue Discount (OID)?

Original Issue Discount (OID) refers to the difference between the face value of a bond or security and the price at which it is originally issued. Instead of paying periodic interest (coupon payments), OID instruments generate returns by appreciating in value over time.

For example, if a 10-year bond with a face value of ₹1,000 is issued at ₹850, the ₹150 difference is the Original Issue Discount. At maturity, the investor receives ₹1,000, making a profit of ₹150 as a capital appreciation.

Key Features of OID Instruments in India:

• Issued at a discounted price to the face value.
• No periodic interest payments (zero-coupon structure).
• Investors earn profits from the price appreciation at maturity.
• Common in Treasury Bills, Zero-Coupon Bonds, and Deep Discount Bonds.
• Taxation applies on the appreciation amount (capital gains or income tax).

Examples of Original Issue Discount in India

1. Treasury Bills (T-Bills)

• T-Bills are short-term government securities issued by the Reserve Bank of India (RBI) with maturities of 91 days, 182 days, and 364 days. They are always issued at a discount and redeemed at full face value.
• Example: A 364-day T-Bill with a face value of ₹100 might be issued at ₹95. At maturity, the investor receives ₹100, earning ₹5 as a return (OID profit).

2. Zero-Coupon Bonds

• Zero-coupon bonds are long-term fixed-income securities that do not pay periodic interest. Instead, they are issued at a steep discount and redeemed at face value.
• Example: A 10-year Zero-Coupon Bond with a face value of ₹1,000 might be issued at ₹600. The investor holds it until maturity and receives ₹1,000, making a profit of ₹400.

3. Deep Discount Bonds

• Deep Discount Bonds (DDBs) are a type of zero-coupon bond that is issued at an extremely low price compared to the face value. These are long-term investments, often maturing in 10-20 years.
• Example: A Deep Discount Bond with a face value of ₹10,000 could be issued at ₹2,500 and redeemed at full value after 15 years.

4. Commercial Papers & Certificates of Deposit

• Certain short-term money market instruments, such as Commercial Papers (CPs) and Certificates of Deposit (CDs), may also be issued at a discount. These instruments are widely used for corporate financing and liquidity management.

How Does Original Issue Discount Work?

OID instruments work on the principle of capital appreciation rather than periodic interest payments. Here's how the process works:

• Step 1: Issuance

The issuing authority (e.g., RBI or a corporate entity) issues bonds or securities at a discounted price.

No interest (coupon) payments are made to investors.

• Step 2: Holding Period

Investors hold the security until maturity.

The value of the security gradually increases toward its face value.

• Step 3: Maturity & Redemption

At maturity, the investor receives the full face value.

The profit earned is the difference between the face value and the original issue price.

Example Calculation:

A bond is issued at ₹900 with a face value of ₹1,000 (OID = ₹100).

At maturity, the investor receives ₹1,000, making a ₹100 gain.

Taxation of Original Issue Discount in India

OID earnings are subject to taxation in India. The tax treatment depends on the type of instrument and the investor’s holding period.

1. Treasury Bills (T-Bills)

• Returns from T-Bills are treated as short-term capital gains (STCG) and taxed as per the investor’s income tax slab.

2. Zero-Coupon Bonds & Deep Discount Bonds

• If held for less than 1 year, gains are taxed as STCG (as per income tax slab).
• If held for more than 1 year, gains qualify as Long-Term Capital Gains (LTCG) and are taxed at 10% without indexation or 20% with indexation.
• Example: If a zero-coupon bond is held for 5 years and sold for a ₹200 profit, LTCG tax applies.

3. Corporate Bonds Issued at a Discount

• Corporate bonds with OID do not qualify for tax exemptions and are taxed as capital gains or interest income.

Why Are OID Instruments Important in India?

1. Alternative to Interest-Based Investments

• OID securities provide an alternative to traditional interest-bearing investments like Fixed Deposits (FDs) and Regular Bonds. Investors looking for capital appreciation over time prefer these instruments.

2. Safe and Low-Risk Investment

• Government-issued OID instruments like T-Bills and RBI Bonds are considered risk-free investments, making them attractive for conservative investors.

3. Effective for Short-Term & Long-Term Goals

• T-Bills (91, 182, 364 days): Best for short-term liquidity management.
• Zero-Coupon Bonds (5-10 years): Suitable for long-term wealth creation.
• Deep Discount Bonds (10+ years): Ideal for investors seeking long-term capital growth.

4. Popular Among Institutional Investors

• OID instruments are widely used by banks, mutual funds, and insurance companies for liquidity management and portfolio diversification.

5. Helps the Government Manage Debt Efficiently

• The Government of India uses T-Bills and bonds issued at a discount to manage short-term borrowing needs, ensuring smooth liquidity in the financial system.

Conclusion

Original Issue Discount (OID) plays a significant role in India's financial markets, providing investors with a safe, fixed-income investment avenue while enabling the government and corporations to raise funds efficiently. Whether through Treasury Bills, Zero-Coupon Bonds, or Deep Discount Bonds, OID securities are essential for both short-term and long-term financial planning.

For investors, OID instruments offer capital appreciation, risk-free returns (in government-backed securities), and tax benefits in some cases. As India’s financial markets continue to expand, OID-based securities will remain a key investment choice for individuals and institutions alike.
