Deep Discount Bonds, also referred to as zero-coupon bonds, are financial instruments that are acquired at a fixed face value, and the full amount of the investment is paid out upon maturity. This means that the bondholder does not receive any regular interest payments but instead earns a profit from the difference between the purchase price and the maturity value. These bonds are commonly used by investors seeking long-term, low-risk investments with a guaranteed return. It is important to carefully consider the risks and potential returns associated with Deep Discount Bonds before making any investment decisions.
