Fixed Income
Quick Definition
An asset class of investments that provide regular, predetermined interest payments and return of principal, including bonds, CDs, and Treasury securities.
What Is Fixed Income?
Fixed income is a broad investment category encompassing securities that pay investors fixed or predictable interest payments on a regular schedule and return the principal at a specified maturity date. The asset class includes government bonds (Treasuries, municipals), corporate bonds, certificates of deposit (CDs), money market instruments, mortgage-backed securities, and preferred stocks. Fixed income serves multiple portfolio functions: providing steady income, preserving capital, reducing volatility, and diversifying against equity risk. The global fixed income market exceeds $130 trillion — significantly larger than the global equity market — making it the world's largest asset class. Fixed income is typically less volatile than equities but also offers lower long-term returns. The asset class is sensitive to interest rate changes (prices fall when rates rise), inflation (which erodes fixed payments' purchasing power), and credit risk (potential default). A balanced portfolio commonly allocates 30-60% to fixed income depending on the investor's age, risk tolerance, and income needs.
Fixed Income Example
- 1A 60/40 portfolio allocates 40% to fixed income — providing stability during the 2022 stock market decline (though bonds also fell that year)
- 2A retiree shifts from 70/30 stocks/bonds to 40/60, increasing fixed income for more predictable retirement income
