A Variable-Rate Demand Bond (VRDB) is a type of municipal bond characterized by a floating coupon rate, which is periodically adjusted. These adjustments typically occur every week, and consequently, the bond’s interest payments fluctuate according to prevailing market conditions. VRDBs offer investors the flexibility to tender the bond back to the issuer or a designated liquidity provider if they choose, typically at par value.
Mechanism of Variable-Rate Demand Bonds
Interest Rate Adjustments
The interest rate on a VRDB is adjusted periodically, often weekly, following one of several benchmark rates or indices such as the London Interbank Offered Rate (LIBOR). The fluctuating rate helps to align the bond’s return with current market conditions.
Put Option and Liquidity
Investors in VRDBs have the right to “put” the bond back to the issuer or a designated liquidity provider on specific reset dates. This feature ensures high liquidity, providing investors with an opportunity to exit their investment relatively easily.
Types of Variable-Rate Demand Bonds
Weekly Reset VRDB
This type of VRDB has interest rates that reset every week based on market conditions. These are most common and offer frequent opportunities for rate adjustments.
Daily Reset VRDB
In this variant, the interest rate is reset daily. This type provides the highest level of rate responsiveness but may involve more administrative overhead.
Special Considerations
Credit Risk
While VRDBs usually have high liquidity, they are subject to the credit risk of the issuer and the designated liquidity provider. It is essential to evaluate the creditworthiness of both to mitigate potential risk.
Call Risk
Some VRDBs can be called before their maturity date, which might affect the bond’s yield. Investors should be aware of call provisions and terms.
Tax Exemption
Many VRDBs are tax-exempt, making them an attractive option for investors in higher tax brackets as they may not have to pay federal, and in some cases, state taxes on the interest earned.
Examples of Variable-Rate Demand Bonds
- City Government VRDB: Issued by a city to finance infrastructure projects.
- School District VRDB: Utilized by a school district to fund new building constructions.
Historical Context and Applicability
Evolution
VRDBs have evolved as flexible funding instruments for municipal entities, particularly beneficial during varying economic cycles. Their adaptability to market conditions has made them popular since the latter half of the 20th century.
Contemporary Relevance
In today’s volatile interest rate environment, VRDBs offer a compelling alternative to fixed-rate bonds by providing potential protection against rising rates.
