Junk Bond: High-Yield Bonds with Higher Default Risk

Junk bonds are high-yield bonds that carry a higher risk of default. Known for financing leveraged buyouts during the 1980s in the USA, junk bonds offer investors potential high returns but come with significant risk.

Types

  • Fallen Angels: Bonds that were once investment-grade but have been downgraded to junk status due to the issuer’s deteriorating creditworthiness.
  • Original Issue High-Yield Bonds: Bonds that were speculative-grade from the time of issuance.

Detailed Explanation

Junk bonds are rated below “BBB” by rating agencies like Standard & Poor’s or below “Baa” by Moody’s, indicating higher credit risk. To compensate for this risk, they offer higher yields compared to investment-grade bonds.

Mathematical Models

The yield of a junk bond can be expressed as:

$$ \text{Yield} = \text{Risk-Free Rate} + \text{Credit Spread} + \text{Liquidity Premium} $$

Importance

Junk bonds play a crucial role in corporate finance, enabling companies with lower credit ratings to access capital. They also offer high returns to investors willing to accept higher risk.

Example

A company with a speculative credit rating might issue a 10-year bond with an 8% yield compared to a similar investment-grade bond yielding 3%. This 5% difference is the risk premium.

  • Leveraged Buyout (LBO): The acquisition of another company using borrowed money.
  • Credit Rating: An assessment of the creditworthiness of a borrower.
  • Credit Spread: The difference in yield between a corporate bond and a risk-free government bond.

Jargon

  • Default: Failure to meet the legal obligations of a loan.
  • Yield: The income return on an investment.

Slang

  • Junk: Informal term for high-yield bonds.
