What Is a Corporate Bond?

4 Min.

A corporate bond is a type of debt issued by a company to raise capital. When an investor purchases a corporate bond, they are loaning money to the company in exchange for a series of interest payments. Corporate bonds can also be traded on the secondary market.

Compared to U.S. government bonds, corporate bonds are generally considered riskier and thus have higher interest rates to compensate for this additional risk. The highest quality and safest bonds are referred to as "Triple-A" bonds, while the least creditworthy are referred to as "junk" bonds.


Corporate bonds represent a form of debt security issued by corporations and traded among investors. Investors provide capital to the company, receiving a predetermined series of interest payments at a fixed or variable rate. The interest payments conclude upon the bond's maturity, and the initial investment is refunded. Typically, the bond's support stems from the corporation's repayment capability, hinging on its anticipated future revenues and profitability. In certain instances, the company's physical assets might serve as collateral.

Exploring Corporate Bonds

High-quality corporate bonds emerge as a secure and prudent choice within the investment landscape. Investors aiming for balanced portfolios strategically incorporate bonds to counterbalance the volatility associated with growth stocks. Throughout their investment journey, individuals often shift towards a greater allocation of bonds, reducing exposure to riskier assets thereby fortifying the preservation of their amassed capital. Retirees commonly favor a higher proportion of bonds to ensure a dependable supplementary income stream.

Comparatively, corporate bonds carry a higher risk profile than U.S. government bonds. Consequently, the interest rates on corporate bonds, even for companies boasting top-tier credit quality, consistently surpass those on government bonds. The disparity between the yields on well-rated corporate bonds and U.S. Treasuries is termed the credit spread.

Bond Credit Ratings by Leading Agencies

The creditworthiness of bonds preceding their issuance to investors undergoes scrutiny from three prominent U.S. rating agencies: Standard & Poor's Global Ratings, Moody's Investor Services, and Fitch Ratings. Each agency employs a distinct ranking system, with the top-tier bonds universally acknowledged as "Triple-A" rated bonds. Conversely, the least creditworthy corporate bonds, labeled high-yield, incur more increased interest rates as compensation for heightened risk, often colloquially called "junk" bonds.

These credit ratings serve as crucial indicators for investors, offering insights into the quality and stability of the respective bonds. Significantly, these ratings wield substantial influence over interest rates, investment preferences, and bond valuations.

Corporate Bond Sales: An Overview

Corporate bonds are typically issued in $1,000 face value blocks, featuring a standardized coupon payment structure. To facilitate the bond offering to investors, corporate issuers often collaborate with investment banks for underwriting and marketing. Investors receive periodic interest payments until the bond reaches maturity, at which point they redeem the face value of the bond. These bonds may carry either a fixed interest rate or a variable rate linked to specific economic indicators.

In some cases, corporate bonds include call provisions, allowing for early prepayment in response to significant interest rate fluctuations. Investors also have the option to sell bonds before maturity, with the resale value determined primarily by the remaining payments due. For broader access to corporate bonds, investors can explore opportunities through bond-focused mutual funds or ETFs.

Corporate Bond Issuance: Financing Strategies

Utilizing debt financing, corporate bonds serve as a prominent capital source for businesses, complementing equity, bank loans, and lines of credit. Frequently employed to secure immediate funding for specific projects, they offer a cost-effective alternative to equity financing, avoiding relinquishment of ownership or control.

The viability of issuing debt securities at favorable coupon rates hinges on a company's sustained earnings potential. Higher perceived credit quality allows companies to issue more debt at reduced rates. For short-term capital needs, corporations may opt for commercial paper, akin to bonds, but with a maturity typically not exceeding 270 days.

Corporate Bonds vs. Stocks: A Distinct Financial Landscape

When an investor purchases a corporate bond, they provide a loan to the company. However, when they buy stock, they acquire ownership in the company.

Stock values fluctuate, impacting the investor's stake accordingly. Gains can materialize through selling the stock at a higher price, receiving dividends, or a combination of both. Contrastingly, bond investors receive interest payments, and their principal is primarily at risk if the company faces insolvency. Notably, even in bankruptcy, bondholders are prioritized over stockholders in debt repayment.

Remarkably, companies can issue convertible bonds that can be converted to company shares if specific requirements are met.


Corporate bonds serve as vital financing tools, enabling investors to lend capital for interest payments. Despite being riskier than government bonds, their credit ratings impact interest rates and investment choices. Issued and traded with standardized features, corporate bonds are often facilitated by investment banks. A balanced portfolio may contain some bonds to offset riskier investments. The percentage devoted to bonds may grow as the investor approaches retirement.
