How do synthetic bonds function?

Understanding the Functionality of Synthetic Bonds

A synthetic bond, in the realm of finance, is a unique type of financial instrument that is designed to emulate the cash flow and risk profile of a traditional bond without the issuer actually having to issue debt. Synthetic bonds exist within the broader category of synthetic assets, which are crafted using a combination of other financial instruments in order to mimic the characteristics of a different asset. Comprehending how synthetic bonds function necessitates a fundamental understanding of bonds, risk profiles, and synthetic assets.

Traditional Bonds Vs. Synthetic Bonds: A Primer

Before digging into the specifics of synthetic bonds, it’s crucial to comprehend what a traditional bond is. In essence, bonds are debt instruments that organizations, frequently corporations or governments, issue to raise money for particular initiatives or general operations. The issuer of the bond guarantees to repay the bond’s face value to the investor at a predetermined future date, known as the maturity date, in addition to regular interest payments over the bond’s lifespan.

In contrast, synthetic bonds do not involve the issuance of debt. Instead, they are structured to simulate the same cash-flows and risk characteristics as traditional bonds by using a combination of other financial instruments. For example, a synthetic bond might be constructed from a risk-free treasury bond and a credit default swap, which is a derivative contract providing insurance against the default risk of a specific issuer.

The Crafting of Synthetic Bonds

The creation of synthetic bonds typically involves two main elements. Firstly, a risk-free asset, typically a government security, is selected. This security will be the underlying asset, providing regular interest payments, anlogous to the coupon payments in a traditional bond. Secondly, a derivative instrument, usually a credit default swap, which provides the added risk associated with the bond issuer’s potential default, is used.

In a credit default swap, one party, known as the protection buyer, pays a regular fee in return for a payment in the event of a specified credit event, such as a bond default. The party selling this protection is called the protection seller. The combined cash flows of the risk-free asset and the credit default swap imitate the cash flows of a traditional bond, thereby creating a synthetic bond.

Purpose and Benefits of Synthetic Bonds

Synthetic bonds add diversity, flexibility, and optionality, especially for institutional investors. They may allow investors to gain exposure to particular assets or risk profiles that would otherwise be inaccessible due to geographical, regulatory, or other constraints. Furthermore, they provide a means for investors to hedge risks or speculate on price movements more precisely.

Portfolio diversification

By combining financial elements in innovative ways, synthetic bonds can provide investors with exposure to assets that would be difficult or impossible to get otherwise. These may include international bonds or bonds issued by companies that have no public debt offerings. This can help investors diversify their portfolios beyond the traditional asset classes, potentially reducing overall investment risk.

Enhanced liquidity

In particular, corporate bonds issued by smaller companies or those in less developed markets may not have the asset liquidity that synthetic bonds do.


Some financial institutions create synthetic bonds as a means of mitigating risk. They can use them to hedge against interest rate fluctuations, credit risk, foreign exchange risk, and more.


Since synthetic bonds don’t involve the issuance of debt, investment banks can trade them without incurring the typical underwriting costs associated with bond issuance.

Final Note

Synthetic bonds represent a sophisticated form of bond investment, allowing experienced bond traders to tailor exposures to different market factors. While the complexity of these instruments may increase the risk of unintended consequences or misuse, they can lead to effective risk management when understood and used properly.
