How Municipal Bonds Are Issued, Step by Step

A municipal bond issue moves through four stages: planning the borrowing, assembling the financing team, pricing and selling the bonds, and closing the transaction, with the investment of the proceeds settled before closing day.

Each stage has its own documents, its own market participants and its own rules, and the stages build on one another from the first planning decision to the day proceeds reach the funds that pay for the project.

The table below maps the stages, and the sections that follow take each one in turn.

How does planning start a municipal bond issue?

Planning is where the issuer decides what it will finance, how much it will borrow, what will repay the bonds and what the securities will look like.

Municipal bond issuance runs at scale: SIFMA reported U.S. municipal bonds outstanding of $4.5 trillion as of 2Q 2026, up 4.8 percent year over year, with $473.8 billion issued in 2026 through September, up 7.3 percent (SIFMA, US Municipal Bonds Statistics).

The first big choice is the repayment source: the MSRB's glossary describes a general obligation bond as typically payable from the issuer's general funds, with most GO bonds carrying the issuer's full faith and credit and often its taxing power, depending on applicable state or local law, and a revenue bond as payable from a specific source of revenue (GO and revenue bonds).

The issuer and its counsel also settle whether the bonds will be tax-exempt or taxable, a decision the tax-exempt and taxable bonds guide covers.

Timing is a planning decision too: GFOA's guidance on investing bond proceeds suggests staging issues over the construction period and not issuing well before spending begins, in part to limit arbitrage liability and negative arbitrage.

Structure choices, such as the years over which principal amortizes and whether the bonds can be called early, are settled here as well, and they shape how long each dollar of proceeds stays invested.

Stage two: the financing team

The second stage is assembling the financing team, and the three roles regulators define most precisely are bond counsel, the municipal advisor and the underwriter.

Bond counsel is typically retained by the issuer, and its opinion customarily states that the bonds have been validly issued and, if tax exemption is intended, that they are tax-exempt, as the MSRB's glossary describes.

A municipal advisor, under Exchange Act Section 15B(e)(4)(A), is a person other than a municipal entity or its employee who advises a municipal entity or an obligated person on municipal financial products or on the issuance of municipal securities, or who solicits a municipal entity.

The scope reaches this page's subject directly: municipal financial products are defined to include guaranteed investment contracts and investment strategies, and investment strategies include plans or programs for investing the proceeds of municipal securities that are not municipal derivatives or guaranteed investment contracts (Exchange Act Sections 15B(e)(3) and 15B(e)(5)).

The definition carries exclusions, so it does not reach an underwriter acting within the scope of an underwriting, a registered investment adviser giving investment advice in that capacity, or an attorney giving traditional legal advice, among others (17 CFR 240.15Ba1-1(d)(2)).

The underwriter is defined by its function: the MSRB's glossary describes an underwriter as a municipal securities dealer that purchases a new issue of municipal securities from the issuer for resale in a primary offering, whether through negotiation or by competitive bid.

The SEC has described that role as generally beginning when the issuer engages the underwriter for a particular issuance and ending at the end of the underwriting period (Release No. 34-70462).

In a negotiated deal, an MSRB interpretive notice applying the MSRB's fair dealing rule to underwriters requires the underwriter to disclose at the earliest stages, for example in an RFP response, that its role is arm's length, that unlike a municipal advisor it does not have a fiduciary duty to the issuer under the federal securities laws, and that the issuer may engage a municipal advisor.

Why an issuer might engage an independent advisor rather than rely on the underwriter is its own question, covered in the independent advisor guide.

Once engaged, an advisor works under the MSRB's conduct rule for municipal advisors, whose paragraph (e) prohibits, among other things, excessive compensation, materially inaccurate invoices, false or misleading statements about the advisor's capacity in RFP responses, fee-splitting with underwriters, undisclosed fee-splitting with providers of investments or services, most payments to obtain engagements, and, for a municipal entity client, principal transactions on the same or a directly related issue or product, subject to an exception for specified fixed income securities.

Dealers face a parallel boundary: the MSRB's rule on financial advisory relationships bars a dealer that has a financial advisory relationship on an issue from acquiring any part of that issue as principal, alone or in a syndicate, or acting as its placement agent, subject to narrow exceptions such as placing an entire issue with a governmental entity, and the bar extends to the dealer's affiliates.

As of April 2026 the MSRB had a pending request for comment on draft amendments touching that rule, so its text may change.

The full roster is on the financing team page.

How is a municipal bond issue priced?

Pricing is the stage at which the interest rate on each maturity and the price the issuer will receive are set, and it happens in one of two ways.

In a competitive sale the purchase is reached by competitive bid, and in a negotiated sale it is reached through negotiation, the two routes the MSRB's glossary definition of an underwriter covers when it describes a municipal securities dealer that purchases a new issue from the issuer for resale in a primary offering.

The fair dealing disclosures described above belong to the negotiated route: that fair dealing interpretive notice applies to negotiated underwritings unless competitive deals are specifically mentioned, and it requires the disclosures at the earliest stages, such as an RFP response.

The offering document for a primary offering is the official statement, which the MSRB's glossary describes as prepared by or on behalf of the issuer and as disclosing material information such as the issue's purposes, how the securities will be repaid and the obligor's financial and economic characteristics.

One product of pricing is the underwriter's discount, which the MSRB's glossary lists among costs of issuance alongside financial advisory, bond counsel, other counsel and rating agency fees.

Pricing also produces the yield the arbitrage definition turns on: under 26 U.S.C. 148(a), a bond is an arbitrage bond when any portion of the proceeds are reasonably expected, at the time of issuance, to be used to acquire higher yielding investments.

What happens at closing?

Closing is where the underwriter's purchase of the new issue from the issuer, the purchase the MSRB's glossary definition describes, becomes final.

Bond counsel delivers its closing opinion, the opinion that the bonds have been validly issued and, if tax exemption is intended, that they are tax-exempt, and the final legal and tax conclusions on an issue are bond counsel's and tax counsel's to make.

Treasury Regulation §1.148-1(b) defines sale proceeds as amounts actually or constructively received from the sale of the issue, including amounts used to pay underwriters' discount or compensation and accrued interest other than pre-issuance accrued interest.

Those proceeds flow into the bond funds, such as a construction fund, a debt service reserve fund, which the MSRB's glossary describes as used to pay debt service if pledged revenues fall short, and a cost of issuance account.

The MSRB's glossary lists costs of issuance as the expenses of selling a new issue, including the underwriter's discount and financial advisory, bond counsel, other counsel and rating agency fees, and notes that a cost of issuance account holds funds pending payment.

GFOA recommends listing the key documents at closing for each issue, such as the tax certificate, escrow documents and the indenture, and identifying the records to keep and how long to keep them.

GFOA's post-issuance guidance adds that a government may outsource tasks such as the rebate calculation and still carries ultimate responsibility for meeting its compliance procedures, a theme the post-issuance compliance guide develops.

Where does reinvestment fit before closing?

Reinvestment decisions are made before closing because the statutory definition of an arbitrage bond starts from the issuer's expectations at the time of issuance.

Under 26 U.S.C. 148(a), a bond is an arbitrage bond when any portion of an issue's proceeds are reasonably expected, at the time of issuance, to be used to acquire higher yielding investments, and intentional use of proceeds that way is treated the same way.

Earning more than the bond yield is not, by itself, the mark of an arbitrage bond: the rules allow higher yields in defined situations, such as temporary periods, a reserve fund and a minor portion of an issue, each covered in the arbitrage guides.

Because the definition starts from expectations at the time of issuance, the plan that matches each fund's expected draws to an investment shape is settled before the deal closes, measured against the bond yield pricing produces.

Where proceeds will sit in a guaranteed investment contract (GIC) or a repurchase agreement, a Bidding Agent's work covers the bid specifications, soliciting qualified providers, managing questions, receiving bids and comparing rate and non-rate terms, and for a GIC, one condition of the fair market value safe harbor in Treas. Reg. §1.148-5(d)(6)(iii) is a bona fide solicitation, which requires written bid specifications timely sent to potential providers, with all material terms and only commercially reasonable terms (§1.148-5(d)(6)(iii)(A)).

The documentation work then delivers the Bidding Agent's and the provider's certifications to bond counsel.

One input is outside the issuer's control: SLGS, the State and Local Government Series Treasury securities, can be suspended by Treasury during debt-limit episodes.

The Secretary's May 1, 2023 debt-limit letter to Congress said Treasury was suspending SLGS issuance, and Treasury's January 17, 2025 description of extraordinary measures lists suspending SLGS sales among its measures, noting that SLGS issuance had averaged about $10 billion per month and that no statute requires Treasury to issue them.

That 2025 document adds that some issuers will have to invest proceeds in alternative assets while SLGS sales are suspended, a wrinkle the SLGS guide covers.

For an independent look at a fund or an upcoming issue, mGIC is an independent, SEC-registered municipal advisor and Bidding Agent that sells no proprietary investment product and is paid by the winning provider, and it offers a free, no-obligation review through the contact page.

The fund-by-fund framework behind those reinvestment choices is in the guide to investing bond proceeds.
