A bond issuer is any entity—be it a government, a municipality, or a corporation—that borrows money from investors by selling bonds. Think of it as the borrower in a very large, public loan. When you buy a bond, you are essentially lending money to the issuer. In return for your cash, the issuer promises to make periodic interest payments, known as coupon payments, over a set period. At the end of that period, when the bond reaches its maturity date, the issuer repays the original loan amount, called the principal, to the bondholder. Issuers use this borrowed capital to finance a wide range of activities, from building new bridges and schools to funding corporate expansion and innovation. Understanding who the issuer is and evaluating their financial stability is the absolute cornerstone of bond investing, as their ability to make good on their promises is what determines whether you get your money back.
Bond issuers are not all created equal. They range from the most powerful national governments to fledgling startup companies, and the type of issuer directly impacts the risk and potential return of a bond.
National governments issue bonds to cover budget deficits and fund public spending like defense, infrastructure, and social programs. These are often called sovereign debt.
State, city, and county governments, as well as other public entities like school districts or transportation authorities, issue municipal bonds (often called “munis”). They use the funds to finance local projects such as building schools, repairing roads, or improving water systems.
Companies of all sizes issue corporate bonds to raise capital. This money might be used to fund research and development, build a new factory, acquire another company, or simply manage day-to-day operations.
For a value investor, buying a bond isn't a passive act; it's an active decision to lend money. Following the wisdom of Benjamin Graham, you must thoroughly investigate who you are lending to. The issuer's identity and financial health are far more important than any market noise.
The core task is to determine if the issuer can afford to pay you back. This isn't just about trusting a credit rating. A true value investor digs into the issuer's financial statements.
The investment world demands higher returns for taking on greater risk. A financially shaky issuer must offer a much higher yield (return) on its bonds to attract lenders compared to, say, the U.S. government. The difference between the yield on a corporate or municipal bond and a risk-free government bond of the same maturity is called the yield spread. A value investor's goal is to find an issuer where the yield spread provides a handsome reward for the actual risk involved, not just the perceived risk. When you find a financially sound company or municipality that the market has undervalued—perhaps due to temporary bad news or general pessimism—its bonds may offer an attractive yield. This gap between the compensation you receive (the yield) and the carefully analyzed risk you are taking is your margin of safety. In bond investing, that begins and ends with the quality of the issuer.
