Municipal Bond Underwriting in the United States
The U.S. municipal bond market set a record in 2024 with over $513 billion in new issuance, surpassing the previous high of $484.6 billion in 2020. Approximately 1,200 broker-dealers are registered with the MSRB, though underwriting activity is concentrated among the top firms—the leading 10 underwriters account for roughly 60–70% of total par value.
Market Structure
Municipal bonds are issued by states, cities, counties, school districts, and special-purpose authorities to fund infrastructure, utilities, healthcare, education, and transportation. Underwriters serve as intermediaries, purchasing bonds from issuers and reselling them to investors. The two primary sale methods are:
- Negotiated Sales
- The issuer selects the underwriter in advance. This method dominates the market and accounts for roughly 80% of new issuance by par value.
- Competitive Sales
- Multiple underwriters bid on the issue. Common for general obligation bonds, particularly from highly rated issuers.

Selecting an Underwriter
The Government Finance Officers Association (GFOA) recommends evaluating underwriters on several criteria beyond price alone:
- Experience with similar credits—matching bond type (GO, revenue, conduit) and issuer size
- Distribution capability—access to retail and institutional investors
- Pricing track record—demonstrated ability to achieve competitive yields
- Aftermarket support—willingness to make secondary markets in the bonds
- Compliance history—clean MSRB/FINRA record with no material disciplinary actions
Regulatory Landscape
All municipal underwriters must register with the MSRB and comply with MSRB Rules G-11 (syndicate practices), G-17 (fair dealing), G-32 (disclosures), and G-37 (political contributions). FINRA provides additional oversight, and the SEC enforces antifraud provisions under the Securities Exchange Act.
