A government bond is essentially a loan to a government. Investors lend capital to a government and generally receive regular interest payments in return.

This can be illustrated using a simplified example. An investor purchases a German government bond with a maturity of ten years and a face value of EUR 100. The face value is the amount on which the bond is based and which is intended to be repaid at maturity.

If the bond has an annual coupon of 3% that is paid once a year, the investor receives EUR 3 each year on a face value of EUR 100. Over ten years, this would amount to total coupon payments of EUR 30 in this simplified example. At maturity, the investor should also receive the face value of EUR 100, provided that the government has not defaulted by that time.

A corporate bond works in much the same way. It is also a loan, but rather than lending money to a government, investors lend it to a company.

The face value in this example could again be EUR 100, and the bond could also have a maturity of ten years. The difference is that the coupon may be higher. Instead of 3%, the bond might pay 4% or 4.5% per year, for example.

With a coupon of 4.5% paid once a year, the investor receives EUR 4.50 each year on a face value of EUR 100. Over ten years, this would amount to total coupon payments of EUR 45 in this simplified example. Compared with the EUR 30 paid by the government bond, the corporate bond therefore generates higher regular coupon income.

This calculation initially illustrates the visible difference: in this example, the corporate bond pays a higher coupon than the government bond. However, the underlying condition is crucial. The face value of EUR 100 will only be repaid in full at maturity if the company is able to meet its obligations.

Every bond investment centres on one simple question: Who owes the money?

The borrower, also referred to as the issuer, is the party that has raised the capital. The issuer must make the agreed coupon payments and repay the face value at maturity. In the case of a government bond, the borrower is a government. In the case of a corporate bond, the borrower is a company.

This difference is important because the market does not automatically assess governments and companies in the same way. A company may have a higher default risk than a government with very strong creditworthiness. From the investor’s perspective, this means that the face value remains exposed to the risk that the borrower may not be able to meet its obligations in full until the bond has been completely repaid.

It is therefore not sufficient to focus exclusively on the size of the coupon. The decisive factor is the borrower to whom the capital is actually being provided. The central question when investing in a corporate bond is therefore: Which company is borrowing the money, and how likely is it that this company will meet its payment obligations?

At the same time, government bonds should not be treated as one uniform category. Not every government has the same level of creditworthiness. Governments also differ in terms of their economic strength, their level of debt and the market’s assessment of their credit quality.

Consequently, not all governments pay the same level of interest in the market. A government with very strong creditworthiness is assessed differently from a government that investors consider to have a higher default risk. Distinguishing between different borrowers is therefore relevant not only for corporate bonds but also for government bonds.

Nevertheless, the central distinction remains: the repayment of a corporate bond depends on the ability of the relevant company to meet its obligations. The repayment of a government bond depends on the ability of the relevant government to meet its obligations. This changes the credit risk, and the market requires appropriate compensation for taking that risk.

The coupon is the regular interest payment made by a bond. It specifies the amount investors are intended to receive in relation to the bond’s face value. With a face value of EUR 100 and a coupon of 3%, the payment would amount to EUR 3 per year, provided that it is made once annually.

However, the coupon should not be confused with the yield of a bond. The actual yield depends, among other factors, on the price at which the bond is purchased, its remaining maturity, the coupon payments made before maturity and the amount repaid at maturity.

For example, if a bond with a face value of EUR 100 is purchased at a price below EUR 100 and repaid at EUR 100 at maturity, the investor receives a capital gain in addition to the coupon payments. By contrast, if the bond is purchased at a price above EUR 100 and repaid at EUR 100, the yield may be lower than the coupon initially suggests.

A higher yield may appear attractive at first. In the case of corporate bonds, however, the yield spread over a comparable government bond often compensates investors for a higher or differently assessed default risk. Investors require a higher yield because they may not attribute the same credit quality to the company as they do to a government with very strong creditworthiness.

The yield spread over a government bond used as a reference is often referred to as the credit spread or credit risk premium. It compensates investors for taking additional credit risk. The credit spread indicates how much additional yield the market considers necessary in order to assume that risk.

The size of the credit risk premium is closely linked to creditworthiness. Creditworthiness describes a borrower’s ability and willingness to meet its payment obligations in full and on time. The higher the borrower’s creditworthiness is considered to be, the more likely the market believes it is that the coupon payments will be made and the face value will be repaid as agreed.

When creditworthiness is very strong, the risk premium is typically lower. When creditworthiness is weaker, the market perceives a higher risk and consequently requires greater compensation.

This can also be illustrated using a simplified example. For a corporate bond issued by a company with solid creditworthiness, the market may consider a yield of 4.5% to be sufficient. In the case of a company that is assessed as being significantly weaker, investors may demand a considerably higher yield because they are only willing to assume the additional risk in return for correspondingly greater compensation.

This makes one point clear: a high coupon does not automatically indicate a better investment. It may also indicate that the market perceives a higher default risk. However, the decisive factor is not the coupon alone, but whether the expected yield adequately compensates investors for the credit risk they are taking.

Ratings are an established market language for assessing creditworthiness. High ratings such as AAA, AA or A generally indicate comparatively strong credit quality and typically lower credit spreads. Weaker ratings, by contrast, are associated with a higher perceived default risk and correspondingly higher risk premiums.

However, a published rating is only one element of the analysis. A professional bond manager should not accept the assessment of a rating agency without further examination but should also conduct an independent analysis of the issuer’s creditworthiness.

The objective of this type of credit analysis is to develop an independent assessment of the issuer’s credit quality. This assessment may correspond with the published rating, but it may also differ from it. For example, a manager may conclude that the financial position of a company has improved or deteriorated before this development is fully reflected in its official rating.

In addition to the issuer’s creditworthiness, the specific terms of the individual bond must also be considered. Corporate bonds differ not only in terms of borrower, coupon and maturity, but also in their legal and economic structures.

Different types of corporate bonds include hybrid bonds, subordinated bonds and convertible bonds. These types of bonds can differ considerably, for example in terms of their repayment priority, payment structure, potential call rights and other contractual conditions.

The bond terms should therefore be carefully analysed and understood before an investment is made. Assessing a corporate bond exclusively on the basis of its coupon is insufficient. A higher coupon may appear attractive, while the terms of the bond may simultaneously contain additional risks.

Specialist analysis can make an important contribution in this context. A bond manager considers not only the size of the coupon and the published rating, but also analyses the issuer, its financial development, the bond terms and the position of the bond within the company’s capital structure.

The central question is which company is receiving the capital and whether the offered risk premium is appropriate for both the actual quality of the borrower and the structure of the bond.

A differentiated analysis can be particularly relevant in the middle rating segments. Issuers in these segments are often not positioned clearly at either the very strong or the very weak end of the credit quality spectrum. An independent assessment can help identify financially solid companies and determine whether the market already adequately reflects the existing opportunities and risks.

This explains why both institutional and private investors use corporate bonds. They are seeking the opportunity to generate higher yields than government bonds can offer. However, this opportunity is subject to an important condition: the credit risk assumed must be adequately compensated, and potential defaults must not outweigh the additional income.

Corporate bonds are therefore not categorically superior alternatives to government bonds. They are a different type of bond, involving a different borrower, a different credit risk and frequently a higher yield. Whether they represent an attractive investment depends significantly on the quality of the analysis and selection process.

A frequently raised concern about corporate bonds relates to defaults. In periods of economic stress, companies may no longer be able to make their coupon payments or repay the face value in full at maturity.

This concern must be taken seriously. If the face value of EUR 100 is at risk, a default can have a considerably greater impact than several years of previously received coupon payments. Default risk is therefore not a secondary issue but a central element in the assessment of corporate bonds.

However, it is important not to treat all corporate bonds in the same way. Defaults are not distributed evenly across all issuers and rating segments. During periods of economic stress, higher default rates are typically more concentrated in weaker credit quality segments.

The global financial crisis of 2008 provides a historical example. In the corporate bond market, weaker rating segments and parts of the high yield market were particularly affected by elevated default risks. At the same time, further differentiation is also necessary within the high yield segment.

The bond market generally distinguishes between investment grade and high yield. Investment grade refers to the upper rating categories. High yield refers to the lower rating categories, which are associated with higher credit risk.

This distinction does not mean that investment grade bonds are risk-free. Nor does it mean that high yield bonds are categorically unsuitable. Rather, it shows that investors need to assess and price risks differently depending on the relevant rating segment.

There are also considerable differences within the high yield market. The upper end of the high yield segment should not be equated with the weakest rating categories. This distinction is important when assessing the areas in which default risks are particularly concentrated and whether the offered credit spread provides adequate compensation.

For investors with an appropriate risk tolerance, the corporate bond market may therefore be attractive in different market environments. Careful selection is a prerequisite. A yield spread can only provide an advantage if the credit risk being assumed is understood and adequately compensated and if potential defaults do not outweigh the additional income.

Corporate bonds and government bonds operate according to similar basic principles. Investors lend capital, generally receive regular coupon payments and expect the face value to be repaid at maturity. In both cases, repayment depends on the relevant borrower being able to meet its obligations.

The central difference lies in the issuer. The borrower behind a government bond is a government, while the borrower behind a corporate bond is a company. Because the market does not automatically assess governments and companies in the same way, corporate bonds often offer higher yields.

However, this yield spread is not an additional return without additional risk. It is referred to as the credit spread or credit risk premium and compensates investors for a higher or differently assessed credit risk.

The coupon should not be confused with the actual yield. The yield of a bond also depends on its purchase price, its remaining maturity, the coupon payments and the amount repaid at maturity.

Other important factors include the issuer’s creditworthiness, its published rating, the specific bond terms and the quality of the selection process. A professional bond manager should develop an independent view of the issuer’s credit quality. This assessment may correspond with the opinion of a rating agency, but it may also differ from it.

It is therefore particularly important to examine the details when investing in corporate bonds. Different types of bonds, such as hybrid bonds, subordinated bonds and convertible bonds, may contain different terms and risks. Investors who focus exclusively on the coupon may overlook precisely the characteristics that are decisive for risk and repayment.

Compared with government bonds, corporate bonds can offer higher return opportunities. However, this advantage is subject to a clear condition: the credit risk must be adequately compensated and carefully analysed. In addition, potential defaults must not outweigh the additional income. This is the fundamental difference between corporate bonds and government bonds.
