Bonds 101: The What and Why of Bond Investing

What you will learn
  • How a bond works
  • The evolution of the market and the key categories of bonds

What is a bond?

At the most basic level, a bond is a fixed income investment representing a loan made by an investor to a borrower, which includes governments, companies, and other entities issuing bonds to raise money from investors when they need new sources of capital to fund their activities.
When investors purchase a government bond, they are effectively lending the government money. When investors buy a corporate bond, they are lending a company money.

Like a loan, a bond pays a periodic interest payment known as a coupon to the bondholder. At the end of the bond's life – called maturity – the principal is paid back to the investor.

Bond investing example

A company wants to build a new manufacturing plant that will cost $1 million. To raise the money needed, company executives decide to issue a corporate bond. Each bond will be issued at $1,000 – this is known as the face value of the bond.

The company – or bond issuer – offers a coupon of 5% per year to be paid quarterly. The bonds will mature after five years, at which time the company will repay the $1,000 face value to each bondholder.

Are bonds and fixed income the same?

Basically, yes. The term fixed income is often used interchangeably with the term bonds. This is because bonds are the most commonly known type of fixed income security.

Technically, “fixed income” covers any security where the issuer is obligated to pay the lender fixed payments at fixed times. What can be confusing for investors is that fixed income does not always mean the bond pays a fixed dollar amount as bonds can have a fixed rate or floating rate. The word 'fixed' in fixed income refers to the obligation to make payments at set times.

Various bond types

Broadly speaking, government bonds and corporate bonds remain the largest sectors of the market. The chart below provides an overview of the key categories of bonds through a potential risk/return lens.

Risk-Return Profiles: Various Bond Types

A chart provides an overview of the key categories of bonds through a potential risk/return lens. The Y-axis represents risk, and X-axis shows return. Four asset classes of bonds are arranged along the graph in terms of increasing risk and return. Government bonds are generally considered low-risk investments, and are plotted in the bottom left-hand corner, with low risk and low returns relative to other bond classes. Next are quasi-government bonds, plotted a little higher and to the right, followed along the same slope by corporate bonds investment grade. Corporate bonds speculative grade have the highest risk and return potential, and are positioned in the upper right-hand corner of the graph.

A word about risk: All investments contain risk and may lose value. Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk, and liquidity risk. The value of most bonds and bond strategies are impacted by changes in interest rates. Bonds and bond strategies with longer durations tend to be more sensitive and volatile than those with shorter durations; bond prices generally fall as interest rates rise, and low interest rate environments increase this risk. Reductions in bond counterparty capacity may contribute to decreased market liquidity and increased price volatility. Bond investments may be worth more or less than the original cost when redeemed. U.S. agency mortgage-backed securities issued by Ginnie Mae (GNMA) are backed by the full faith and credit of the United States government. Securities issued by Freddie Mac (FHLMC) and Fannie Mae (FNMA) provide an agency guarantee of timely repayment of principal and interest but are not backed by the full faith and credit of the U.S. government. References to Agency and non-agency mortgage-backed securities refer to mortgages issued in the United States. Income from municipal bonds in the U.S. are exempt from federal income tax and may be subject to state and local taxes and at times the alternative minimum tax; a strategy concentrating in a single or limited number of states is subject to greater risk of adverse economic conditions and regulatory changes. Sovereign securities are generally backed by the issuing government. Obligations of U.S. government agencies and authorities are supported by varying degrees, but are generally not backed by the full faith of the U.S. government. Portfolios that invest in such securities are not guaranteed and will fluctuate in value. Inflation-linked bonds (ILBs) issued by a government are fixed income securities whose principal value is periodically adjusted according to the rate of inflation; ILBs decline in value when real interest rates rise. Treasury Inflation-Protected Securities (TIPS) are ILBs issued by the U.S. government. Investing in foreign-denominated and/or -domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets.

The credit quality of a particular security or group of securities does not ensure the stability or safety of an overall portfolio. The quality ratings of individual issues/issuers are provided to indicate the credit-worthiness of such issues/issuer and generally range from AAA, Aaa, or AAA (highest) to D, C, or D (lowest) for S&P, Moody’s, and Fitch respectively.
