Key Takeaways
- Third party guarantees bond payments if issuer defaults.
- Improves credit rating and lowers issuer's borrowing costs.
- Guarantee covers principal, interest, or both payments.
What is Guaranteed Bond?
A guaranteed bond is a debt security issued by an entity where a third party, known as the guarantor, promises to pay the principal and/or interest if the issuer defaults. This guarantee adds an extra layer of security beyond the issuer’s own creditworthiness, often enhancing the bond’s appeal to investors.
These bonds differ from other types because the backing comes from a guarantor rather than collateral or government support, offering a unique risk profile that you should understand when evaluating fixed income options.
Key Characteristics
Guaranteed bonds combine issuer obligations with third-party assurance, improving investor confidence. Key features include:
- Third-Party Guarantee: A guarantor such as a bank, insurance company, or parent corporation backs payment obligations, reducing default risk.
- Coverage Scope: The guarantee may cover interest payments, principal repayment, or both, activating only if the issuer defaults.
- Credit Impact: Often result in higher credit ratings, sometimes approaching AAA status, which lowers borrowing costs.
- Issuer Types: Commonly issued by subsidiaries or municipalities, with guarantors like bond insurers or government agencies.
- Alternative Names: Also referred to as endorsed bonds or joint bonds in some markets.
How It Works
When an issuer sells a guaranteed bond, it promises to pay coupon interest and return the principal at maturity. If the issuer faces insolvency or bankruptcy, the guarantor steps in to fulfill these payments, protecting investors from losses.
This structure lowers the issuer’s cost of capital by improving creditworthiness and can make the bond more attractive to risk-averse investors. However, the guarantee’s strength depends on the guarantor’s financial health, so it’s crucial to assess both parties.
Examples and Use Cases
Guaranteed bonds are used across various sectors where added security is essential for attracting investment. Some examples include:
- Corporate Subsidiaries: A subsidiary may issue bonds guaranteed by its stronger parent company, similar to how Delta might support its debt issuance to secure better terms.
- Municipal Projects: Local governments often use guarantees from banks or insurers to fund infrastructure, enhancing bond ratings and investor confidence.
- Railroads and Utilities: Historically, railroads issued guaranteed bonds backed by parent firms to stabilize financing amid volatile industries.
- Bond Funds: Investors seeking exposure to guaranteed bonds may consider diversified options like the BND fund, which includes various bond types with credit enhancements.
Important Considerations
While guaranteed bonds provide added security compared to unsecured bonds, they still carry risks tied to the guarantor’s solvency. If the guarantor cannot fulfill its commitment, investors face potential losses.
Additionally, market risks such as interest rate fluctuations affect bond prices regardless of guarantees. When evaluating guaranteed bonds, review the bond’s face value and call provisions, as some may be callable bonds that the issuer can redeem early, impacting returns.
Final Words
Guaranteed bonds offer an added layer of security by involving a third-party guarantor, which can reduce your investment risk and potentially improve returns. To make the most informed decision, compare guarantees and credit ratings across different bonds before committing your capital.
