Deep Discount Bonds (DDBs) are debt instruments that are issued at a deep discounted value and the face value is fully paid to the investors on maturity. These bonds have no coupon rate and therefore are referred to as zero interest bonds. The bondholder’s return comes entirely from the difference between the issue price and the redemption value. The maturity period of deep discounted bonds usually ranges from 10 to 30 years. It is designed to meet long term financial requirements of the investors who are not seeking immediate returns. Deep discount bonds are often grouped with zero-coupon bonds.
For instance, the face value of the bond is Rs 1 lakh. The issuer issued a deep discount bond for Rs 25,000 and redeemed it at Rs 1 lakh, having a maturity period of 20 years. The difference of Rs 75,000 is the investor’s return on bonds.
