Investing in Bonds

A bond is a loan you make to a government or corporation. The borrower (issuer) agrees to pay you regular interest (coupon payments) and return your original investment (principal) on a set date called the maturity date.

Bonds are called fixed-income securities because the interest payments are predictable and set at purchase.

Component	Meaning	Example
Issuer	The borrower	U.S. Treasury, Apple Inc.
Coupon Rate	Annual interest paid	4% per year
Maturity	When the bond ends	10 years
Face Value	Principal repaid at maturity	$1,000

One key rule: bond prices move inversely to interest rates. When rates rise, existing bond prices fall, and vice versa.

Different bond types carry different levels of risk and return potential.

Bond Type	Typical Risk	Key Benefit
Government Bonds	Very Low	Safe and predictable income
Municipal Bonds	Low	Interest is often federal tax-exempt
Corporate Bonds	Moderate	Higher yield than government bonds
Treasury Inflation-Protected (TIPS)	Very Low	Principal adjusts with inflation
High-Yield (Junk) Bonds	High	Greater return potential

• U.S. Treasury Bonds: Backed by the federal government. Maturities range from 2 to 30 years.
• Municipal Bonds: Issued by states and cities. Interest is generally exempt from federal income tax.
• Corporate Bonds: Issued by companies. Higher risk than government bonds, but typically pay more.
• TIPS: Protect against inflation by adjusting the principal with the Consumer Price Index (CPI).

Understanding these four metrics helps you compare and choose bonds effectively.

Metric	What It Tells You	How to Use It
Coupon Rate	Annual interest as % of face value	Compare income against inflation
Yield to Maturity (YTM)	Total return if held to maturity	The best apples-to-apples comparison
Credit Rating	Issuer's ability to repay	Stick to A or higher for lower risk
Duration	Sensitivity to interest rate changes	Shorter duration = less price volatility

• Yield to Maturity (YTM) accounts for the coupon, price paid, and time remaining. It is the most useful number when comparing two bonds.
• Credit ratings are issued by agencies like Moody's, S&P, and Fitch. Ratings of BBB or higher are considered investment-grade.
• Duration is measured in years. A bond with a duration of 7 will drop roughly 7% in value if interest rates rise by 1%.

Bonds carry less risk than stocks but are not risk-free.

Risk Type	What Happens	How to Manage It
Interest Rate Risk	Bond prices fall when rates rise	Shorten duration; use bond ladders
Inflation Risk	Fixed payments lose purchasing power	Add TIPS or I-Bonds to the mix
Credit Risk	Issuer defaults on payments	Stick to investment-grade issuers
Liquidity Risk	Hard to sell before maturity	Use bond ETFs for easier trading

Bond laddering is one of the most effective ways to manage interest rate risk. Buy bonds with staggered maturities (for example, 2, 4, 6, 8, and 10 years). As each bond matures, reinvest the proceeds at current rates.
