What is a bond?

Quick Summary

A bond is a loan from an investor to a borrower, typically a corporation or government, that pays interest until its maturity date when the principal is repaid.

When you purchase a bond, you are essentially lending money to the issuer, which can be a corporation, municipality, or the federal government. In return for the loan, the issuer promises to pay you a specified rate of interest during the life of the bond and to repay the face value of the bond when it matures. This makes bonds a cornerstone of fixed-income investing, providing predictable returns and capital preservation for portfolios.

Bonds are a key component of a diversified investment portfolio. They are often considered less risky than stocks because bondholders have a higher claim on the issuer’s assets in the event of bankruptcy. However, it is crucial to understand that all bonds carry some degree of risk, primarily credit risk and interest rate risk.

Credit risk refers to the possibility that the bond issuer will fail to make timely interest payments or repay the principal at maturity. Interest rate risk is the risk that rising market interest rates will cause the value of existing bonds to fall.

Before investing, it’s wise to assess the creditworthiness of the bond issuer. Credit rating agencies like Moody’s and Standard & Poor’s provide independent evaluations, which are a useful starting point for your research. For a deeper understanding of government-issued securities, you can review information from the U.S. Department of the Treasury.

There are several major types of bonds available to investors:

  • Corporate Bonds: Issued by companies to fund operations or expansion.
  • Municipal Bonds: Issued by states, cities, or other local government entities, often offering tax-exempt interest.
  • Treasury Bonds: Issued by the U.S. federal government and considered to have minimal credit risk.
  • Agency Bonds: Issued by government-sponsored enterprises like Fannie Mae or Freddie Mac.

Understanding these different categories can help you select bonds that align with your financial goals and risk tolerance. The bond market is vast and offers options for nearly every investment strategy.

Common Mistake

Assuming your bond cost is just a simple percentage

The most costly mistake is thinking your Oregon contractor license bond premium is a fixed rate like 1% or 2% of the bond amount. In practice, your final cost is determined by an underwriter reviewing your personal credit score, financial statements, and business history. Applicants with lower credit often pay 3-5% or more. What slows this down is not having your financials ready. The part most applicants underestimate is how much a strong credit profile can reduce your annual premium.

  • Your personal credit score is the primary factor in your final rate.
  • Have 2 years of business and personal financial statements prepared for review.
  • A higher bond amount doesn't mean a proportionally higher cost; underwriting is key.
