Municipal bonds, or munis, are debt obligations issued by public entities to fund public projects such as schools, hospitals, and highways. In the US, municipal bonds have been tax-exempt since 1913. Muni bonds are generally considered safe, with a 10-year cumulative default rate of 0.1% since 1970. However, investors should be aware of the risks associated with different types of municipal bonds, such as revenue bonds, which are nonrecourse to the state or local government issuer and are instead the obligation of a private entity. Insured muni bonds are those that are insured by policies written by commercial insurance companies, who promise to pay principal and interest payments to bondholders in the event that the issuer defaults. The safety of insured muni bonds depends on the creditworthiness of the insurer and the issuer, and the quality of the investment.

What You'll Learn

Insured muni bonds are safe due to their low default risk
Municipal bonds, or muni bonds, are debt obligations issued by public entities to fund public projects such as schools, hospitals, and highways. They can be categorised as either general obligation or revenue bonds, depending on the source of their interest payments and principal repayments. Muni bonds are generally considered a safe investment due to their low default risk. Since 1970, the 10-year cumulative default rate for municipal bonds has been 0.1%.
Some municipal bonds are insured by policies written by commercial insurance companies, further reducing the risk of default. In the event of a default, the insurer is obligated to pay the principal and interest payments to bondholders. When considering insured muni bonds, investors should assess the creditworthiness of both the insurer and the issuer. Insured muni bonds are often backed by a pledge of taxes or dedicated revenue streams from essential public services, providing a stable source of repayment.
The presence of insurance on muni bonds can impact their yield performance relative to uninsured bonds. During the 2008 financial crisis, insured muni bonds exhibited higher yields than comparable uninsured bonds, raising questions about the value of insurance during periods of financial distress. However, the overall low default risk associated with muni bonds, combined with the additional protection provided by insurance, makes insured muni bonds a relatively safe investment option.
It is worth noting that the attractiveness of insured muni bonds can depend on the credit quality of the issuer and the insurer. In some cases, highly-rated issuers may be subsidising lower-rated issuers, resulting in a negative value for the highly-rated issuers. Additionally, the cost of municipal bond insurance is borne by taxpayers, which is an important consideration in evaluating its worth.
In summary, insured muni bonds are considered safe due to their low default risk, which is further mitigated by the presence of insurance. However, investors should carefully assess the specific characteristics of each bond, including the creditworthiness of the issuer and insurer, to make informed investment decisions.

Insurers and issuers' creditworthiness should be considered
Municipal bonds are debt obligations issued by states, cities, counties, and other governmental entities to raise funds for public projects such as schools, hospitals, and highways. They can be categorized into general obligation bonds and revenue bonds. The former is issued by governmental entities and backed by revenues from specific projects or dedicated taxes, while the latter is secured by revenues generated by the issuer or certain taxes.
Some municipal bonds are insured by commercial insurance companies, providing an additional layer of security. This insurance is designed to protect investors by ensuring the timely payment of principal and interest in the event of an issuer default. The presence of insurance enhances the creditworthiness of the bond, making it more attractive to investors.
When considering insured municipal bonds, it is crucial to assess the creditworthiness of both the insurer and the issuer. Creditworthiness is a key factor in determining the safety of these bonds. Investors should examine the financial condition, credit history, and ability to meet payment obligations of both parties. Credit ratings from agencies like Moody's and Standard & Poor's can provide valuable insights into the creditworthiness of the insurer and issuer.
The increased use of municipal bond insurance benefits both issuers and investors. Insurers lend their higher credit ratings to issuers, improving their standing with credit rating agencies and reducing borrowing costs. Insured bonds also offer greater liquidity as they are more appealing to investors seeking financial security.
In summary, while municipal bond insurance provides added protection, investors should carefully evaluate the creditworthiness of both the insurer and issuer before purchasing insured municipal bonds. This due diligence helps ensure a more informed decision-making process and a better understanding of the associated risks and benefits.

Insured muni bonds have higher yields than uninsured bonds
Municipal bonds, or muni bonds, are debt obligations issued by public entities to fund public projects such as schools, hospitals, and highways. While municipal bonds are generally considered safe, with a low default risk, there are different types of municipal bonds, each carrying a different level of risk. These include general obligation bonds and revenue bonds. Revenue bonds, for example, are secured by revenues generated by the issuer or by certain taxes, such as sales or fuel taxes.
Some municipal bonds are insured by policies written by commercial insurance companies, providing an additional layer of security for bondholders. In the event of a default by the issuer, the insurer guarantees the timely payment of principal and interest to bondholders. Insured muni bonds often have higher credit ratings than uninsured bonds, as the insurer is typically more highly rated than the issuer. This higher credit rating results in lower interest costs for issuers, which can lead to higher yields for insured muni bonds compared to their uninsured counterparts.
For example, consider a municipality issuing a 25-year, $100 million bond with a single-A credit rating and a 4.0% yield. By purchasing bond insurance, the municipality can increase the bond's credit rating to AA, resulting in a lower yield of 3.75%. The net interest savings over the life of the bond can be significant, even after factoring in the cost of insurance.
Additionally, insured muni bonds provide greater reassurance and predictability for bondholders, as evidenced by the stability of insured bond prices during periods of market volatility. For instance, during a week in May 2015 when Moody's downgraded the City of Chicago's credit rating, the uninsured 10-year bond prices fell by nearly 8%, while the city's insured bonds maintained their value, keeping yields steady.
In summary, insured muni bonds offer higher yields than uninsured bonds due to the improved credit rating and marketability that insurance provides. This allows issuers to secure lower interest rates, resulting in potential savings that can enhance the overall yield of the bond.

Muni bonds are debt obligations issued by public entities
Municipal bonds, or muni bonds, are debt obligations issued by public entities. They are used to fund public projects such as the construction of schools, hospitals, highways, bridges, and other infrastructure. These bonds act like loans, with bondholders becoming creditors who are entitled to regular interest payments and the return of their original investment, known as the principal, by the maturity date.
Muni bonds can be categorized into two types: general obligation bonds and revenue bonds. General obligation bonds are issued by governmental entities and are backed by the "full faith and credit" of the issuer. This means that the issuer has the power to tax residents to pay bondholders. Revenue bonds, on the other hand, are not backed by the government's taxing power but by revenues from a specific project or source, such as highway tolls or lease fees.
Muni bonds are considered relatively safe investments due to their low default rates compared to corporate bonds. Since 1970, the 10-year cumulative default rate for municipal bonds has been 0.1%. Additionally, some muni bonds are insured by commercial insurance companies, providing an extra layer of security for bondholders. However, it is important to consider the creditworthiness of both the insurer and the issuer when investing in insured bonds.
Despite the relatively low risk associated with muni bonds, investors should be aware of certain risks. These include call risk, where the issuer may repay the bond early if interest rates decline, and credit risk, where the issuer may experience financial difficulties that impact their ability to make interest and principal payments. The market price of muni bonds is also subject to interest rate risk and inflation risk, which can affect the overall return on investment.

Insured muni bonds are secured by a pledge of taxes
Municipal bonds, or muni bonds, are debt obligations issued by public entities to fund public projects such as schools, hospitals, and highways. They are generally considered a safe investment, with a low default risk. Since 1970, the 10-year cumulative default rate for municipal bonds has been 0.1%. Muni bonds are often tax-exempt, with interest on the bonds being free from federal income tax and state taxes in the state of issuance.
Muni bonds can be insured by commercial insurance companies, providing an extra layer of security for investors. Insured muni bonds are secured by a pledge of taxes or a dedicated revenue stream from an essential public service. This means that if the issuer defaults, the insurer will step in and make the payments to bondholders. Insured muni bonds are considered a safer option, especially in the case of a financial crisis, when issuers may struggle to make payments.
The benefits of bond insurance are twofold, helping both investors and issuers. For investors, the insurance provides protection against default and guarantees timely payments of principal and interest. This was evident in the case of Puerto Rico, where insurers continued to make payments on insured bonds when the issuer defaulted. Insurers also provide due diligence, simplifying the research process for investors.
For issuers, bond insurance improves marketability and reduces the cost of issuance. It can attract more investment, particularly for smaller issuers or those with a shaky credit profile. By insuring their bonds, issuers can improve their credit rating and access cheaper funding.
However, it's important to note that the value of municipal bond insurance has been debated. Some studies suggest that during the 2008 financial crisis, insured bonds had higher yields than comparable uninsured bonds, indicating that insurance may not provide value when it's needed most. Additionally, the cost of insurance is borne by taxpayers, which is another factor to consider.

In theory, municipal bond insurance should reduce the cost of municipal borrowing by reducing expected default costs, providing due diligence, and improving price stability and market liquidity. However, empirical studies have shown that insured bonds have higher yields than comparable uninsured bonds during financial crises, suggesting that insurance may be less valuable when it is needed most. Therefore, the safety of insured muni bonds depends on various factors, including the creditworthiness of the insurer and the issuer.
When considering investing in insured muni bonds, it is important to assess the creditworthiness of both the insurer and the issuer. Additionally, investors should be aware of the potential for over-insurance, where highly-rated issuers may subsidize lower-rated issuers, resulting in a negative value for the highly-rated issuers.
If you are looking for a safer fixed-income option, you may consider investing in a treasury money market fund or short-term treasuries. These options typically carry less risk than investing in insured muni bonds.
