Bond Investing Basics: A Complete Guide

Understand how bonds work and their role in a balanced investment portfolio.

Bonds are a fundamental building block of any diversified investment portfolio. They provide regular income, lower volatility than stocks, and serve as a counterbalance during stock market downturns.

What Is a Bond?

A bond is essentially a loan you make to a government or corporation. In return, the issuer promises to:

  • Pay you regular interest (called the "coupon")
  • Return your principal at maturity

Key Bond Terms

  • Face Value (Par): The amount paid back at maturity (typically $1,000)
  • Coupon Rate: The annual interest rate paid on the face value
  • Maturity Date: When the bond principal is repaid
  • Yield: Your actual return, considering the price you paid
  • Credit Rating: Assessment of the issuer's ability to pay (AAA to D)

Types of Bonds

Government Bonds

  • Treasury Bonds — backed by the full faith of the government, safest
  • Municipal Bonds — issued by state/local governments, often tax-exempt
  • Agency Bonds — issued by government-sponsored enterprises

Corporate Bonds

  • Investment Grade — rated BBB or higher, lower risk, lower yield
  • High Yield (Junk) — rated below BBB, higher risk, higher yield

International Bonds

Issued by foreign governments or corporations, adding currency risk and geographic diversification.

How Bond Prices Move

Bond prices and interest rates move inversely:

  • When interest rates RISE, existing bond prices FALL
  • When interest rates FALL, existing bond prices RISE
This is because new bonds offer better rates, making existing bonds less attractive (and vice versa).

Bond Risks

1. Interest rate risk — prices fall when rates rise 2. Credit risk — issuer may default on payments 3. Inflation risk — fixed payments lose purchasing power 4. Liquidity risk — some bonds are hard to sell before maturity 5. Call risk — issuer may repay early when rates drop

Bonds in Your Portfolio

The traditional guideline is: bond allocation = your age (e.g., 30 years old = 30% bonds). However, modern portfolios may adjust this based on risk tolerance and interest rate environment.
