Revenue Bond
What Is a Revenue Bond?
A revenue bond is a type of municipal bond supported by the revenue from a specific project, such as a toll bridge, highway, or local stadium, rather than by general tax revenues.
When a local government wants to build a facility that will make money—like a toll road, an airport terminal, a water treatment plant, or a sports stadium—it often issues a revenue bond. Investors buy these bonds to lend the government money for construction. In return, the government promises to pay back the investors using the income generated by that specific facility. Unlike General Obligation (GO) bonds, which are backed by the "full faith and credit" (taxing power) of the municipality, revenue bonds are "non-recourse." This means if the toll road doesn't get enough traffic or the stadium doesn't sell enough tickets, the bondholders cannot demand that the city raise taxes to pay them back. The risk is tied entirely to the success of the project. Because of this specific risk, revenue bonds usually pay a higher interest rate (yield) than GO bonds to compensate investors. They are a critical tool for project finance, allowing specific users of a service to pay for its infrastructure rather than the general taxpayer base.
Key Takeaways
- Revenue bonds are municipal securities used to finance specific income-generating public projects.
- Repayment is secured solely by the revenue generated by the project (e.g., tolls, user fees, rent).
- They differ from General Obligation (GO) bonds, which are backed by the full taxing power of the issuer.
- Because they are riskier than GO bonds, revenue bonds typically offer higher yields.
- Common examples include bonds for airports, hospitals, toll roads, and utilities.
- Interest income is generally exempt from federal income tax.
How It Works
The mechanics of a revenue bond are centered on the "Trust Indenture." This legal contract outlines how the revenue from the project will be managed. 1. **Revenue Collection:** Money collected (e.g., tolls) goes into a special fund. 2. **Operations & Maintenance:** Usually, the facility's operating costs are paid first. 3. **Debt Service:** The remaining net revenue is used to pay interest and principal to bondholders. 4. **Reserve Fund:** Many revenue bonds require a "debt service reserve fund" to cover payments if revenue temporarily dips. If revenue falls short, the bond may default. However, many revenue bonds have a "rate covenant," which is a legal promise that the issuer will raise rates (e.g., increase tolls) if necessary to ensure enough revenue is collected to cover the debt.
Types of Revenue Bonds
Different sectors issue revenue bonds with unique risks.
| Type | Source of Revenue | Risk Factor | Example |
|---|---|---|---|
| Utility Bonds | Water/Sewer/Electric bills | Low (Essential service) | City Water Authority |
| Transportation | Tolls, landing fees | Medium (Economic cycles) | Turnpike Authority |
| Housing | Rent payments | Medium (Occupancy rates) | State Housing Finance Agency |
| Industrial Development (IDB) | Lease payments from corp | High (Corporate credit) | Factory financing |
Important Considerations for Investors
Investors should carefully analyze the "debt service coverage ratio" (DSCR). This ratio compares the project's annual net revenue to its annual debt obligations. A DSCR of 2.0x means the project earns twice as much as it needs to pay the bonds, which is a strong safety margin. A DSCR close to 1.0x is risky. Also, consider the essential nature of the service. A water utility revenue bond is generally safer than a convention center bond. People will pay their water bill even in a recession, but they might stop attending conventions. Finally, like most municipal bonds, the interest is typically tax-free at the federal level, and often at the state level if you live in the state where the bond was issued. This makes them attractive to high-net-worth investors.
Real-World Example
The "City Airport Authority" issues $100 million in revenue bonds to build a new terminal. The bonds pay 4% interest.
Common Beginner Mistakes
Risks to watch for:
- Assuming all muni bonds are safe (revenue bonds default more often than GO bonds).
- Ignoring the specific revenue source (a hospital bond is very different from a toll road bond).
- Failing to check if the bond is subject to the Alternative Minimum Tax (AMT) (some private-activity revenue bonds are).
- Not checking the call provisions (the issuer might repay the bond early).
FAQs
Generally, yes, but they carry more risk than General Obligation bonds. Essential service bonds (water, sewer, power) are very safe, while bonds for private activities (industrial development, housing) carry higher default risks.
Interest from most revenue bonds is exempt from federal income tax. However, some "private activity bonds" (like for a stadium or private airport terminal) may be subject to the Alternative Minimum Tax (AMT).
If the project fails to generate enough revenue, bondholders may not get paid. Unlike GO bonds, bondholders cannot force the city to raise taxes to cover the loss. They may have to negotiate a restructuring or take ownership of the asset.
A double-barreled bond is backed by two sources: specific project revenue AND the general taxing power of the issuer. It combines the features of a revenue bond and a GO bond, offering higher safety.
Yields are higher to compensate investors for the specific project risk. Since the repayment depends on a single stream of income rather than a broad tax base, the probability of default is slightly higher.
The Bottom Line
Revenue Bonds are a cornerstone of municipal finance, allowing communities to build essential infrastructure without burdening the general taxpayer. For investors, they offer an attractive blend of tax-free income and higher yields compared to General Obligation bonds. It is the practice of targeted financing. By tying the debt to the success of the project, revenue bonds enforce a discipline of economic viability. However, the "no-tax-hike" guarantee comes with a catch: if the project fails, the bondholder loses. Investors looking for tax-exempt income should carefully evaluate the reliability of the revenue stream—whether it's water bills (safe) or convention center fees (volatile). Diversifying across different sectors (utilities, transport, healthcare) can help mitigate the project-specific risks inherent in revenue bond investing.
