What is a Bond?
A bond is a loan you give to a company or government in exchange for regular interest payments. When the bond matures, the issuer gives you back the face value, which is the amount you put in. Bonds are less volatile than stocks and give you a steady income. Treasury bonds are a great example because they pay interest every six months and return the principal when they mature.
The Role of Bonds in Finance
Bonds provide steady income and help investors balance their portfolios. They are often used for retirement planning or risk management because they tend to be safer than stocks. Bond values can fluctuate in the secondary market due to changes in interest rates and economic conditions, making monitoring important for investors who may sell before maturity.
How Bonds Differ from Stocks
Stocks represent ownership in a company and come with higher growth potential and volatility. Bonds involve lending money to an issuer for a fixed interest return. Stocks can offer larger gains, but bonds provide predictable income and lower risk. Investors often combine stocks and bonds to stabilize their portfolios.
How Do Bonds Work
Buying a bond means lending money to an issuer in exchange for interest payments, known as coupons. For example, a $1,000 bond with a 4% coupon rate pays $40 annually until maturity. The issuer returns the full face value at the end of the bond term, providing predictable income.
The Life Cycle of a Bond
A bond begins when issued with a set face value, interest rate, and maturity date. Interest payments are made periodically, commonly every six months. Upon maturity, the issuer repays the initial investment. Selling a bond before maturity may result in gains or losses depending on market conditions.
Interest Payments and Coupons:
- Coupon Rate: Fixed annual interest rate of the bond.
- Coupon Payments:Â Regular cash payments based on the coupon rate.
- Payment Schedule: Most bonds pay interest semiannually.
- Market Impact: Bond prices fall if new bonds offer higher interest rates.
Types of Bonds in the United States
Treasury Bonds and Treasury Bills
Treasury securities are U.S. government loans seen as very safe.
- Treasury Bills (T-bills): Short-term, under one year, sold below face value, no periodic interest.
- Treasury Notes (T-notes): Medium-term, 2 to 10 years, interest paid semiannually.
- Treasury Bonds (T-bonds): Long-term, 20 to 30 years, interest paid semiannually.
Municipal Bonds
Issued by local governments for public projects. Interest is often exempt from federal taxes and sometimes state or local taxes. Returns are generally lower than taxable bonds but offer tax advantages.
Corporate Bonds
Companies issue corporate bonds to raise capital. Interest payments depend on the company’s credit rating. Higher-rated bonds are safer, while lower-rated bonds offer higher yields but greater default risk.
Agency Bonds and Mortgage-Backed Securities
Issued by government-sponsored entities like Fannie Mae or Freddie Mac. Mortgage-backed securities pool home loans for investors. Prepayment risk exists if borrowers refinance early, potentially reducing expected returns.
