A high yield bond is also commonly known as a junk bond. This type of bond is considered risky due to its lower credit rating, but it offers a higher return on investment compared to safer investments. Another synonym for high yield bonds is speculative bonds, indicating the uncertain returns they may bring. Some investors refer to them as non-investment grade or subordinated bonds, which highlights the fact that they are lower in priority to other bondholders in the event of default. Risky bonds, non-grade bonds, non-investment grade bonds and speculative bonds are other terms used to describe high yield bonds and can often be used interchangeably. These types of bonds can be tempting investments for some, but they come with a high degree of uncertainty, prompting investors to carefully assess their options before investing.
