Municipal Bonds: The Lower-Risk Investment With a Catch

• Municipal bonds help governments raise money for public projects.
• They can offer investors relatively stable income.
• Some municipal bonds provide tax advantages.

When investors think about fixed-income investments, corporate bonds and government securities usually get most of the attention. But there is another category that can offer steady income, relatively lower default risk and, in some cases, tax advantages: municipal bonds.

Municipal bonds, often called “munis,” are debt securities issued by state, county and local governments to raise money for public projects such as roads, schools, hospitals and other infrastructure.

In return for lending money to the issuer, investors typically receive periodic interest payments and get their original investment back when the bond matures.

Why Investors Buy Municipal Bonds

One of the biggest attractions of municipal bonds is their potential tax advantage.

In the United States, interest from many municipal bonds is exempt from federal income tax. This can make them particularly attractive to investors in higher tax brackets, even though their interest rates may be lower than those offered by riskier investments.

Munis are also generally associated with lower default risk than corporate bonds. That makes them more suitable for investors who prioritize capital preservation and predictable income over aggressive returns.

Two Major Types of Municipal Bonds

Not all municipal bonds carry the same level of risk. Their structure largely depends on how the government plans to repay investors.

General Obligation Bonds

General obligation, or GO, bonds are backed by the financial strength of the issuing government.

Repayment can come from general government revenues, including taxes. Because they are not dependent on the success of a specific project, they are generally viewed as more stable than some revenue bonds.

Revenue Bonds

Revenue bonds work differently. Their repayment depends on money generated by a particular project or service.

For example, a bond financing a toll road may rely on toll collections to repay investors. This means the financial performance of the underlying project can have a greater impact on the bond’s ability to pay.

The Risks Investors Should Not Ignore

Calling municipal bonds “low risk” does not mean they are risk-free.

Interest rates remain one of the biggest factors affecting their market value. When interest rates rise, existing bond prices generally fall. When rates decline, bond prices tend to increase.

Maturity also matters. Long-term municipal bonds are typically more sensitive to interest-rate movements than short-term bonds.

Revenue bonds can carry additional risk because their repayment depends on the performance of the underlying project. A weak economy or declining demand for a service can reduce the revenue available to repay bondholders.

Liquidity is another consideration. Some municipal bonds may not trade as frequently as other securities, meaning investors who need to sell quickly could have difficulty finding a buyer at their desired price.

Some bonds also contain call provisions, allowing the issuer to repay the bond before its scheduled maturity. This can become a disadvantage for investors when interest rates fall because they may have to reinvest their money at lower rates.

How Much Do You Need to Invest?

Municipal bonds are commonly issued in denominations of $5,000, although investors can gain exposure through municipal-bond mutual funds and exchange-traded funds (ETFs), which can provide access to a broader portfolio.

Their maturities can also vary considerably, from relatively short-term securities to bonds lasting several decades.

The Bottom Line

Municipal bonds can offer investors a combination of relatively lower risk, regular income and potential tax benefits. But the trade-off is that their returns are generally more modest than those of higher-risk assets.

For investors seeking stability rather than rapid capital growth, munis can play a useful role in a diversified fixed-income portfolio.

The key is not to look at the tax advantage or interest rate alone. Investors should also examine the issuer’s financial strength, the bond’s repayment structure, maturity, liquidity and exposure to changing interest rates before committing capital.
