Debentures vs Bonds: Meaning, Differences & Key Features Explained

Introduction

The terms bonds and debatentures are often used interchangeably in India, especially in corporate and financial discussions.

However, while they share similarities, there are technical and regulatory differences between the two.

This article provides a neutral, educational breakdown of Debentures vs Bonds, exploring their meanings, structures, risks, and differences in the Indian context.

What Are Bonds?

A bond is a debt security where the issuer borrows money from investors and agrees to repay it with periodic interest (coupons) and principal at maturity.

Bonds are typically characterized by:

• fixed or floating interest payments

• clear maturity dates

• defined repayment structure

• tradability on exchanges (if listed)

• use by governments, PSUs, NBFCs, and corporates

Bonds in India are issued under SEBI’s Non-Convertible Securities (NCS) Regulations.

What Are Debentures?

A debenture is a broader term that refers to any debt instrument issued by a company, typically without specific asset backing.

In India, “debentures” historically referred to unsecured corporate debt, but today, NCDs (Non-Convertible Debentures) may be secured or unsecured.

Debentures may include:

• secured NCDs

• unsecured NCDs

• subordinated debentures

• perpetual debentures

• convertible debentures (unless explicitly non-convertible)

Debentures represent a company’s promise to repay borrowed funds.

Legal Differences Between Bonds & Debentures in India

Bonds:

• Issued by governments, PSUs, corporates

• Often associated with higher security and clear legal frameworks

• May be secured or unsecured

• Regulated heavily by RBI (for G-Secs) and SEBI (for corporates)

Debentures:

• Issued primarily by companies

• Defined under the Companies Act, 2013

• Can be secured or unsecured

• Convertible debentures allowed

• Governed by SEBI NCS Regulations + Companies Act

While similar, debentures are more closely tied to corporate borrowing structures.

Types of Bonds

1. Government Bonds (G-Secs)

Issued by the Government of India.

2. State Development Loans (SDLs)

Issued by state governments.

3. PSU Bonds

Issued by public-sector enterprises.

4. Corporate Bonds

Issued by private or public sector companies.

5. Perpetual Bonds

No maturity; often issued by banks.

6. Securitised Bonds

Backed by loan pools.

These bonds vary significantly in structure and purpose.

Types of Debentures

1. Secured Debentures

Backed by assets or cash flows.

2. Unsecured Debentures

Backed only by issuer creditworthiness.

3. Convertible Debentures

Convertible into equity at a later date.

4. Non-Convertible Debentures (NCDs)

Most common in the Indian retail market.

5. Subordinated Debentures

Lower priority in repayment hierarchy.

Debentures often reflect a firm’s corporate financing strategy.

Secured vs Unsecured: Where Each Fits

Many investors confuse secured vs unsecured with bonds vs debentures.

Bonds can be:

• Secured

• Unsecured

Debentures can also be:

• Secured

• Unsecured

Security status depends on the instrument, not the name.

Interest Structures

Both bonds and debentures may have:

• fixed-rate coupons

• floating-rate coupons

• step-up/step-down interest

• zero-coupon structure

• cumulative payout options

Interest structures are defined in the Information Memorandum (IM).

Risks Associated with Each

Neutral and educational — not suitability guidance.

1. Credit Risk

Correlates with issuer’s financial strength.

2. Liquidity Risk

Trading activity differs by issuer and instrument.

3. Interest-Rate Risk

Market yields impact prices of both bonds and debentures.

4. Structural Risk

Convertible or subordinated debentures carry additional complexity.

5. Regulatory Risk

Risk levels vary based on issuer category, not on the “bond” or “debenture” label.

Regulatory Framework

Bonds

• Government bonds regulated by RBI

• Corporate bonds regulated by SEBI

• Listed bonds follow SEBI NCS + LODR regulations

• Trading through exchanges

Debentures

• Governed by Companies Act, 2013

Listed NCDs trade actively on exchanges.

“Terminology defines risk.”

Risk depends on issuer strength & structure—not name.

Conclusion
