Bonds explained: lending, income, and risk

A practical introduction to coupons, principal, prices, and repayment.

A bond is a debt investment. You lend to an issuer under specified terms, generally receiving interest and repayment of principal at maturity. Credit quality, contractual protections, and the price you pay determine much of the investment's risk and potential return.

Read a bond quote

A $1,000 face-value bond with a 4% coupon pays $40 a year under its stated payment schedule. Buying it for $950 changes your yield; it does not normally change that fixed coupon. Accrued interest and transaction costs can make the settlement amount differ from the quoted clean price.

Identify the ways to lose money

The issuer may default. Market yields may rise and reduce the resale price. Inflation may erode purchasing power. A call may return principal earlier than expected, and thin trading may make a sale expensive.

Match the bond to the job

If the goal is a known expense, compare maturity timing, payment certainty, and credit risk. If the goal is diversification, consider how the bond behaves when other holdings decline. A high-yield corporate bond may respond more like risky equity than a short Treasury bill.

Before buying, read the offering documents and compare yield-to-maturity, yield-to-call where applicable, fees, and tax treatment. A larger coupon is not a complete ranking system.
