A variable‑rate demand note (VRDN), also called a variable‑rate demand obligation (VRDO), is a long‑term municipal debt security whose interest rate resets at short‑term intervals (daily, weekly, or monthly) to a prevailing money‑market rate plus a spread. VRDNs have an embedded “put” (demand) feature that allows investors to tender the note back for repayment at specified short notice (commonly one day or seven days). Because of their liquidity and credit support, VRDNs are widely used in money‑market and municipal funds.
Key takeaways
– VRDNs are long‑term municipal bonds with short‑term interest‑rate resets and a short‑notice put (tender) right.
– Interest rates on VRDNs track short‑term money‑market rates (e.g., prime) plus a spread and are reset periodically.
– VRDNs typically include credit and liquidity enhancements (letters of credit or standby bond purchase agreements) provided by highly rated banks; the bank’s short‑term credit quality heavily influences the VRDN’s perceived safety.
– They are generally sold in large denominations (commonly $100,000 minimum); most retail investors access them via money‑market or municipal mutual funds.
– VRDNs issued by municipalities are usually federally tax‑exempt and sometimes state tax‑exempt in the state of issuance.
– VRDNs constitute a large share of securities held by many money‑market funds (roughly 76% of securities in money market funds, per asset‑manager data).
How VRDNs work — core features
– Floating interest rate: Rate resets periodically to a money‑market benchmark plus an issuer spread.
– Demand (put) feature: Investors can require immediate (or near‑term) repayment by tendering the security to a remarketing agent, trustee, or other intermediary. The next put date is effectively the maturity for liquidity purposes.
– Remarketing agent: When an investor tenders a VRDN, a remarketing agent attempts to sell (remarket) the note to a new investor at the current reset rate.
– Liquidity facility / credit enhancement: To backstop failed remarketings, issuers typically arrange a letter of credit (LOC) or a standby bond purchase agreement from a bank. If remarketing fails, the liquidity provider purchases the note or ensures payment. Because of this, market perception of the VRDN often mirrors the liquidity provider’s credit standing.
– Minimum denomination: VRDNs are commonly issued in $100,000 increments, which limits direct retail ownership.
Why issuers and investors use VRDNs
– For issuers (municipalities): VRDNs let them borrow long term while paying short‑term rates that reset when market rates change.
– For investors/funds: VRDNs provide short‑term liquidity, relatively low interest‑rate sensitivity, and returns that historically have low correlation with equities—helpful for diversification in cash‑like portfolios.
Taxation
– Interest on municipal VRDNs is typically exempt from federal income tax. Many issues are also exempt from state income tax in the issuing state (but not always). Tax rules for municipal securities are complex and subject to IRS requirements; consult a tax advisor for your specific situation.
Risks to consider
– Liquidity/failed remarketing risk: If the remarketing agent can’t place a tendered note and the liquidity provider is unable or unwilling to purchase, investors may face delays or reduced repayment.
– Counterparty/credit risk: The safety of many VRDNs depends heavily on the liquidity provider (bank providing LOC or standby purchase agreement). If that bank’s credit worsens or it fails, the VRDN’s liquidity and creditworthiness can be impaired.
– Interest‑rate risk: While short‑term resets limit duration risk, higher short‑term rates can increase financing costs for issuers and decrease market value under stress.
– Tax risk: If a security’s tax status changes (or if IRS rules are violated), expected tax exemptions could be jeopardized.
– Minimum investment/retail access: Direct ownership usually requires high minimums; retail investors typically use pooled funds.
Can you invest in VRDNs?
– Direct purchase: Possible but generally limited to institutional investors or very large individual accounts due to minimums (commonly $100,000). Purchase is done via broker‑dealers or institutional desks.
– Indirect/retail access: Most individual investors gain exposure by buying money‑market funds or municipal bond funds that hold VRDNs. Many institutional money‑market funds hold a large share of VRDNs.
Practical steps — how to evaluate and invest in VRDNs
For individual investors (via funds)
1. Decide your objective: cash management (liquidity), tax‑exempt income, or short‑term municipal exposure.
2. Choose the vehicle: select money‑market funds (municipal or prime) or short‑term municipal bond funds that disclose VRDN holdings.
3. Check holdings and strategy: review the fund’s prospectus/holdings to confirm exposure to VRDNs and the fund’s stated credit/longevity profile.
4. Examine fees and liquidity: compare expense ratios, minimum investments, and redemption terms.
5. Confirm tax treatment: ensure the fund’s distributions align with your state tax situation (some funds provide state‑specific municipal exposure).
6. Monitor periodically: watch for changes in the fund’s credit concentration, liquidity provider names, and yields.
For institutional or direct investors
1. Define constraints: required denomination, desired maturity profile, tax status, and liquidity needs.
2. Vet the issue: obtain the official statement and credit documents for each VRDN. Key items: remarketing agreement, letter of credit or standby bond purchase agreement (name of bank, expiration, terms), and the remarketing agent’s identity and track record.
3. Assess counterparty risk: evaluate the liquidity provider’s short‑term rating and balance‑sheet strength—VRDN credit often mirrors the provider more than the municipal issuer.
4. Understand reset/put schedule: confirm frequency of interest resets and the required notice period for tender.
5. Confirm remarketing mechanics and failed remarketing provisions: know what happens if a remarketing fails (automatic purchase by liquidity provider, etc.).
6. Review tax counsel or compliance: confirm federal/state tax exemption status and any IRS use restrictions.
7. Negotiate documentation and price: include legal review, counsel opinions (if needed), and confirm settlement procedures.
8. Monitor ongoing: track bank counterparties, changes to LOCs/agreements, and remarketing performance.
How VRDNs are redeemed (the put/remarketing process)
– Investor tenders (puts) the note on a put date or with required notice.
– Remarketing agent attempts to sell the note to a new investor at the reset rate.
– If remarketed successfully, the tendered investor receives cash and the new investor takes the note.
– If remarketing fails, the liquidity provider (LOC or standby purchaser) steps in to purchase or finance the note, ensuring repayment to the tendering investor. The liquidity facility is the safety net that makes VRDNs function as highly liquid investments in practice.
Portfolio role and allocation guidance
– Cash alternative/tax‑efficient cash: For taxable investors seeking municipal tax advantages, VRDN exposure via a municipal money‑market fund can be an efficient cash alternative.
– Short‑term allocation: Use VRDNs (or funds holding them) for short‑duration, low‑volatility allocations—size positions based on liquidity needs and counterparty concentration rules.
– Diversification: Because VRDN returns historically show low correlation with stocks, they can help diversify cash and fixed‑income allocations. Always limit exposure to any single liquidity provider or issuer to manage counterparty risk.
Practical checklist before buying VRDN exposure
– Is the investment vehicle suitable for retail (fund) or institutional (direct)?
– Who is the liquidity provider and what are its ratings? How long is the LOC in force?
– Who is the remarketing agent; what is their track record?
– What is the reset frequency and put notice requirement?
– What are the tax characteristics and any state tax benefits?
– What happens on failed remarketing; is there an immediate backstop?
– What are minimums, fees, and redemption rules?
– How does this holding fit your overall cash and counterparty risk limits?
When to consult professionals
– Tax issues: consult a tax advisor about municipal tax exemption and state/local treatment.
– Large direct purchases: use legal counsel and municipal‑market specialists to review offering documents, LOC agreements, and remarketing contracts.
The bottom line
VRDNs combine the long‑term financing needs of municipal issuers with the short‑term liquidity and rate resets sought by cash and money‑market investors. Their safety and liquidity depend heavily on the creditworthiness and terms of supporting banks and remarketing agents. Retail investors typically gain VRDN exposure through municipal money‑market or short‑term muni funds; institutional investors may buy directly but must perform detailed due diligence on liquidity and credit support arrangements. As always, review tax consequences and consult a financial or tax advisor before investing.

Market Participants and Roles
– Issuers: Typically state and local governments, municipal authorities, or other public issuers that want long-term financing but prefer to pay short-term interest.
– Investors: Money market funds, institutional investors, and indirectly, retail investors via mutual funds or municipal bond funds.
– Remarketing agents: Broker-dealers that sell (remarket) tendered VRDNs to new investors each put date or tender event.
– Liquidity providers: Banks that provide letters of credit (LOCs) or standby bond purchase agreements (SBPAs) to back timely payment of principal if remarketing fails.
– Trustees/Paying agents: Entities that manage payments and the mechanical aspects of tenders and settlements.
How VRDNs Work — Step-by-Step (Issuer Perspective)
1. Issue structure: The issuer designates the bonds as long-term municipal debt with a floating interest rate and an embedded put (tender) option at specified reset intervals (daily, weekly, or monthly).
2. Credit enhancement: The issuer secures liquidity and credit support — commonly a bank LOC or SBPA — to assure investors that tendered funds will be paid even if remarketing fails.
3. Remarketing agent appointment: The issuer hires a dealer to remarket tendered securities at each put date and to set the new floating interest rate tied to a reference money market rate plus a spread.
4. Sale to investors: Securities are sold to institutional buyers (e.g., money market funds) in minimum denominations (frequently $100,000).
5. Tender/reset cycle: At each put date, investors can tender (put) the VRDN back for payment. The remarketing agent attempts to find new buyers; if successful, the security continues with new investors. If unsuccessful, the liquidity provider purchases the tendered notes under the LOC/SBPA.
6. Ongoing disclosures: Issuer provides continuing disclosure and tax compliance information to maintain tax-exempt status and market transparency.
How VRDNs Work — Step-by-Step (Investor Perspective)
1. Decide access route: Direct purchase (large minimums) or via a money market / municipal mutual fund.
2. Review offering documents: Note the tender frequency, remarketing agent, liquidity provider name and terms, replacement costs, spread formula, and tax-exempt status.
3. Evaluate counterparties: Check credit ratings of the liquidity provider and remarketing agent; the VRDN’s effective short-term credit largely reflects the liquidity provider’s creditworthiness.
4. Monitor reset dates: Understand when you can tender and what notice is required (e.g., one or seven days).
5. Tender/hold decision: On each reset date, decide whether to hold or tender; if tendered, expect cash back in the stated notice period, or the liquidity provider to step in.
Practical Steps for Investors (Checklist)
– Confirm accessibility: If you’re a retail investor, consider funds that invest in VRDNs rather than attempting purchase directly.
– Inspect liquidity facility details: Who is the LOC provider, what is the tenor, and under what conditions can it be drawn?
– Review tender/reset mechanics: Frequency of resets, notice requirements, and settlement timing.
– Consider credit risk: VRDN credit is tied more to the liquidity provider than the underlying municipal issuer — check the bank’s short-term rating.
– Compare yields: Look at the current reset rate, historical spread behavior, and how that compares to comparable short-term instruments.
– Tax treatment: Verify federal tax exemption and, if relevant, state tax treatment for your state of residence.
– Diversify exposure: Avoid excessive concentration in a single issuer or liquidity-provider-backed VRDN.
Practical Steps for Issuers (Checklist)
– Secure a reputable liquidity provider: A well-rated bank lowers borrowing costs and increases investor demand.
– Hire an experienced remarketing agent: Effective remarketing reduces failed remarketings and reliance on LOC draws.
– Ensure compliance and disclosure: Maintain IRS requirements for tax-exempt status and provide investors with timely information (e.g., via EMMA — Electronic Municipal Market Access).
– Price the spread competitively: The margin over the reference rate should reflect market conditions and the credit support in place.
– Plan for contingency: Have clear provisions for failed remarketings and monitor the liquidity provider’s credit.
Examples
1) Interest calculation (simple)
– Terms: Reference rate = 5.00% (e.g., weekly money market benchmark), spread = 0.25% (25 bps).
– VRDN reset rate = 5.00% + 0.25% = 5.25% annual coupon (pro-rated for period if reset weekly).
– Payment: If paid weekly, weekly interest = (5.25% / 52) × principal.
2) Tax-equivalent yield comparison
– Suppose a VRDN offers a tax-exempt yield of 4.50% and you are in a 35% federal tax bracket.
– Tax-equivalent yield = tax-exempt yield / (1 − tax rate) = 4.50% / (1 − 0.35) = 4.50% / 0.65 = 6.92%.
– Interpretation: A taxable security would need to yield ~6.92% to match the after-tax return of the 4.50% tax-exempt VRDN.
3) Tender/remarket scenario (illustrative)
– An institutional investor tenders $10 million of VRDNs on a weekly put date.
– Remarketing agent offers the tendered notes to the market but fails to find buyers for $2 million.
– Under the LOC, the liquidity provider purchases the $2 million to satisfy tender obligations, preserving investor liquidity and leaving the liquidity provider holding the notes until remarketed again or other arrangements are made.
Risks and What to Watch For
– Liquidity provider risk: If the bank providing the LOC/SBPA experiences financial distress, the short-term credit for the VRDN can deteriorate quickly.
– Failed remarketing risk: While LOCs mitigate immediate liquidity risk, repeated failed remarketings can signal market dislocation and expose the issuer or liquidity provider to losses.
– Counterparty concentration: A fund or investor overly concentrated in VRDNs backed by a single bank faces heightened counterparty risk.
– Interest rate risk: Although VRDN interest rates reset frequently, the underlying long-term obligations remain; changes in credit spreads or market liquidity can affect availability and yields.
– Tax risk: VRDN interest is typically tax-exempt, but IRS rules and audits might affect a bond’s tax-exempt status under certain circumstances—issuers must comply with tax rules to preserve exemption.
– Operational risk: Tender mechanics, settlement, and intermediaries must function reliably; any operational failure can delay liquidity.
Regulatory, Accounting, and Tax Considerations
– Tax-exempt status: VRDNs issued by municipalities often carry federal tax-exempt interest; some issues may be state-tax-exempt in the state of issuance. Compliance with IRS rules (e.g., private use restrictions) is essential.
– Disclosure: Issuers must comply with municipal disclosure rules and provide updates via platforms such as EMMA.
– Money market fund rules: Because VRDNs are commonly held by money market funds, changes in money market regulation (e.g., liquidity or credit requirements) can affect demand.
– Accounting treatment: For institutional holders and issuers, accounting for short-term tender features, liquidity facilities, and derivatives (if any) must follow applicable GAAP or IFRS guidance.
Portfolio Uses and Strategy
– Cash alternative: VRDNs can serve as a higher-yielding, tax-advantaged alternative to other short-term instruments, particularly for tax-sensitive investors.
– Diversification: VRDNs typically have low correlation with equities and longer-duration bonds, making them attractive for diversification.
– Yield enhancement for municipal funds: Money market funds and municipal funds use VRDNs to boost yield while maintaining liquidity features for investors.
Recent Market Dynamics (what investors should monitor)
– Bank credit cycles: Because VRDNs often rely on bank LOCs, shifts in bank creditworthiness materially impact VRDNs’ short-term risk perception.
– Interest rate environment: Rapid changes in short-term rates change the reset level for VRDNs frequently.
– Liquidity in secondary markets: The ability of remarketing agents to find buyers depends on overall municipal and money market liquidity; stressed markets can raise failed remarketing risk.
Comparison to Similar Instruments
– Variable-Rate Demand Obligations (VRDOs): Terms often used interchangeably with VRDNs, VRDOs include similar floating-rate, puttable municipal bonds.
– Auction Rate Securities (ARS): ARS had long-term nominal maturities with periodic auctions for short-term liquidity; ARS experienced significant failures in 2008, illustrating liquidity risk. VRDNs rely on LOCs rather than auctions and are structured to provide more reliable liquidity.
– Floating-rate notes (FRNs): FRNs reset interest based on a reference rate but typically lack a put option and the same short-term liquidity assurances that VRDNs provide through LOCs.
Sample Due-Diligence Questions for Investors
– Who is the liquidity provider and what is its short-term rating?
– What are the exact terms of the LOC/SBPA, including termination provisions?
– Who is the remarketing agent and what is their track record?
– What is the minimum denomination and is direct purchase feasible for me?
– How often does the interest rate reset and what reference rate is used?
– Are the interest payments federally tax-exempt? State-tax exempt in my state?
– Where can I read ongoing disclosure documents (e.g., EMMA access)?
Concluding Summary
Variable-rate demand notes (VRDNs or VRDOs) are long-term municipal bonds with short-term cash-like liquidity provided by an embedded put option and credit enhancement (LOC or SBPA). They allow issuers to borrow long-term at short-term interest rates while offering investors frequent reset dates and tax-exempt interest. VRDNs are widely used by money market funds and institutional investors; retail investors typically access them through mutual funds. The effective short-term credit of a VRDN depends heavily on the bank or institution providing the liquidity facility, so careful attention to counterparties, remarketing arrangements, tender mechanics, tax treatment, and contingency plans is essential. When used appropriately within a diversified portfolio and after proper due diligence, VRDNs can offer tax-efficient, low-correlation returns with high liquidity — but they are not risk-free, and counterparty and market liquidity risks should be monitored closely.
