Debentures are a popular financial instrument widely used by corporations and governments to raise capital from the public. As an investor, understanding the various types of debentures available in the market is crucial to making informed investment decisions. In this blog, we will explore the different types of debentures and focus on the specific types prevalent in India’s financial landscape.

Types of Debentures

  1. Secured Debentures:

Secured debentures are backed by specific assets of the issuing company. These assets serve as collateral, providing an added layer of security to investors. In the event of default or bankruptcy, secured debenture holders have a higher chance of recovering their investment through the liquidation of the underlying assets.

  1. Unsecured Debentures:

Unlike secured debentures, unsecured debentures are not backed by any specific collateral. They are issued based on the creditworthiness and reputation of the issuing company. As a result, unsecured debentures carry higher risk compared to secured debentures, and investors may demand a higher interest rate (coupon) to compensate for the increased risk.

  1. Convertible Debentures:

Convertible debentures offer investors the option to convert their debentures into equity shares of the issuing company after a specified period. This provides investors with the opportunity to participate in the company’s growth and potentially benefit from capital appreciation.

  1. Non-Convertible Debentures (NCDs):

Non-convertible debentures do not carry the option of conversion into equity shares. These debentures are redeemed at maturity, and investors receive the principal amount along with the agreed-upon interest.

Types of Debentures in India

Fixed-Rate Debentures:

Fixed-rate debentures come with a predetermined interest rate, and the interest remains constant throughout the tenor of the debenture. Investors receive regular interest payments at fixed intervals, providing them with a predictable income stream.

Floating Rate Debentures:

Floating rate debentures have variable interest rates that are linked to a benchmark, such as the prevailing government bond yield or a market interest rate index. The interest rate adjusts periodically based on changes in the benchmark, ensuring that investors receive a competitive interest rate in line with market conditions.

Zero-Coupon Debentures:

Zero-coupon debentures do not pay regular interest like other debentures. Instead, they are issued at a discount to their face value and redeemed at face value upon maturity. The difference between the issue price and face value represents the interest earned by the investor.

Callable Debentures:

Callable debentures provide the issuer with the option to redeem the debentures before their maturity date. This typically occurs when interest rates decline, allowing the company to issue new debentures at a lower interest rate. While callable debentures offer flexibility to the issuer, they may result in premature redemption for investors, impacting their expected returns.

Puttable Debentures:

Puttable debentures offer investors the option to sell back their debentures to the issuer before maturity at a predetermined price. This feature provides investors with an exit route in case of adverse market conditions or changes in their investment objectives.

Perpetual Debentures:

Perpetual debentures have no fixed maturity date and, therefore, no obligation for the issuer to redeem the principal amount. Instead, the issuer pays periodic interest indefinitely. However, some perpetual debentures may carry a call option that allows the issuer to redeem the debentures after a specified period.


Understanding the various types of debentures is vital for investors seeking to diversify their portfolios and achieve financial objectives. Each type of debenture comes with its unique features, risk profiles, and potential returns. As an investor, conducting thorough research, evaluating risk tolerance, and seeking expert advice are critical to making informed decisions.

In India’s dynamic financial landscape, debentures present a compelling investment opportunity for both individual and institutional investors. By delving into the world of debentures and recognizing the specific types prevalent in India, investors can embark on a journey towards building a robust and balanced investment portfolio. Remember, knowledge and prudence are the keys to successful debenture investing, enabling investors to navigate the market with confidence and achieve their financial aspirations.
