Junk bonds, also called high-yield bonds, are debt securities issued by companies with lower credit ratings. It offers higher interest rates to compensate investors for the increased default risk.

Understanding junk bonds and how they function is crucial for investors considering these high-risk, high-yield debt instruments. Despite the name, junk bonds can be a valuable investment for accepting the inherent risks. They offer higher returns in exchange for the higher volatility.

What are Junk Bonds?

Junk bonds, or high-yield bonds, are debt securities issued by companies with credit ratings below investment grade (generally below BBB by S&P or Baa by Moody’s). These bonds are considered riskier than investment-grade bonds because the issuing companies are more likely to default on their debt obligations.

Investors are willing to take on this added risk because junk bonds offer the potential for higher interest payments (junk bond interest rates) compared to safer bonds. Companies that issue junk bonds often have poor financial health or less financial history, operate in volatile industries, or are relatively new to the market.

Because of the inherent risk, junk bonds are classified as high-risk, high-yield debt instruments. Before investing, it’s essential to understand junk bonds’ meaning and the factors contributing to their higher risk profile.

Junk bonds are issued across various sectors and are available in multiple markets, including India. Here, the market is less developed than others. The junk bond market’s size and liquidity can vary significantly by region.

How Do Junk Bonds Work and How Are They Rated?

When a company needs to raise capital, it can issue bonds. In a typical scenario, businesses with little or no credit ratings can sell high-yield or junk bonds. The user company has the authority to set the repayment parameters, which include the terms and conditions of the payment, such as the percentage of the yield, maturity date, and repayment cycle. Investors are willing to buy the bonds to offer the company the required funds.

Just like other bonds, junk bonds also give periodic interest payments and the return of their principal at maturity to their investors. The company is legally obligated to repay bondholders according to the agreed-upon terms. Because companies issue junk bonds with a higher risk of default, the probability of loss is greater.

Junk bond trading also occurs on secondary markets, allowing investors to buy and sell these securities before they mature. The junk bond market has grown significantly and increased over the past few years.

Credit rating agencies, like Moody’s and S&P, assess the credit worthiness of junk bond issuers. These ratings are essential for investors to understand the risk associated with a bond. Junk bonds are generally categorised into three risk levels. These risk ratings allow investors to assess the risk of default and make informed investment decisions.
