Bond market (fixed-income market)

Characteristics and common instruments

Bonds vary by issuer, term, interest structure and credit risk. Common categories include:

• Government bonds — sovereign debt used to finance public spending.
• Municipal bonds — local government obligations, often with tax features.
• Corporate bonds — debt issued by companies, which may be investment grade or high yield.
• Structured and asset-backed securities — claims backed by pools of loans or receivables.

These instruments are collectively described as debt instruments or fixed-income securities, and they can be plain‑vanilla (fixed coupon) or feature variable rates, convertibility, or callable/putable options.

How the market operates

Primary issuance is typically arranged by investment banks, while secondary trading may be over-the-counter or on trading venues. Key participants include issuers, institutional investors (pension funds, mutual funds, insurance companies), retail investors and market makers. Price and yield move inversely: when prevailing interest rates rise, existing bond prices fall, and vice versa. Credit ratings, maturity, liquidity and tax treatment influence pricing.

History, size and significance

The bond market has existed for centuries in various forms, expanding markedly with modern finance and government borrowing needs. Today it represents a global market measured in the trillions of dollars, with the U.S. market among the largest. Its scale and depth make it central to public finance, corporate funding and portfolio management, and it plays a major role in setting benchmark interest rates.

Uses, risks and notable facts

Bonds are used to finance infrastructure, budget deficits, corporate investment and more. They serve conservative investors seeking income and diversification. Major risks include credit/default risk, interest-rate risk, inflation risk and liquidity risk. Market indicators such as the yield curve are closely watched as signals of economic expectations.
