What Is a Bond?
A bond is a loan you make to a government, municipality, or corporation. In return, the issuer pays you a fixed interest rate on a regular schedule and repays the full face value when the bond matures.
How Bonds Work
Bonds are classified as fixed-income securities because they provide a predictable stream of income. They're generally considered lower-risk than stocks, though they typically offer lower long-term returns. Government bonds (like U.S. Treasury bonds) are backed by the full faith of the federal government and are among the safest investments available. Corporate bonds carry more risk but offer higher yields to compensate.
One critical relationship to understand: bond prices move inversely to interest rates. When the Federal Reserve raises rates, existing bonds with lower coupon rates become less attractive, so their prices drop. When rates fall, existing bonds become more valuable, and prices rise.
Why Bonds Matter for Your Financial Goals
Bonds play a stabilizing role in a diversified portfolio. While stocks provide growth, bonds provide income and ballast during market downturns. Most financial educators recommend increasing your bond allocation as you approach retirement, since the steady income and lower volatility help protect your savings when you can least afford big losses.
Key Takeaway
Bonds won't make you rich, but they help protect what you've built. Understanding the bond-interest rate relationship is essential for any investor.

Interest Rate
An interest rate is the cost of borrowing money or the reward for saving it, expressed as a percentage. When the Federal Reserve raises rates, borrowing costs more but savings earn more. When rates drop, borrowing becomes cheaper but savings earn less.
Yield
Yield is the income returned on an investment, expressed as a percentage. Dividend yield measures annual dividends relative to stock price. Bond yield measures total expected return if held to maturity. Unusually high yields can signal increased risk.
Asset Allocation
Asset allocation is the strategy of dividing your investment portfolio across different asset classes — such as stocks, bonds, and cash — to balance risk and potential reward based on your goals, timeline, and risk tolerance.
Diversification
Diversification is the investment strategy of spreading your money across different asset classes, industries, and geographies to reduce risk. The core principle: don't put all your eggs in one basket.
