Muni Reference Data from MBIS

Thu, 26 Mar 2026 22:09:23 GMT

MBIS is launching comprehensive reference data on 1.5M+ muni bonds in 2026.

Muni bond issuance hit record highs in 2025. According to SIFMA, muni bond issuance topped $580 billion last year, and the MSRB reported that in 2025, new-issue volume set a record for the second consecutive year. Gross supply may reach $600 billion in 2026 as infrastructure demands grow and issuers pursue more refinancings.

Behind those numbers sits a structural reality that defines the municipal bond outlook heading into 2026: more than 1.5 million active bond issues from over 50,000 issuers, each with its own call provisions, coupon structures, credit enhancements, sinking fund schedules, and variable rate terms. No other corner of fixed income is this fragmented, and every new issue adds to the operational burden of keeping that information current and accurate. This is why Municipal Bond Information Services (MBIS) is expanding into a space the market urgently needs.

MBIS Launches Comprehensive Muni Reference Data

MBIS is launching comprehensive bond reference data in 2026, covering over 1.5 million active U.S. muni bonds from more than 50,000 issuers. The offering is delivered in partnership with SQX (Securities Quote Xchange) and EDI (Exchange Data International) .

Our dataset will serve as a foundational layer for firms that need reliable municipal bond data on the securities they trade, hold, analyze, and report on, whether the use case is pricing, compliance, risk management, portfolio analytics, or regulatory reporting.

Built on Proven Infrastructure

MBIS was founded as a consortium of eleven municipal security trading firms that assembled to aggregate market data and improve price transparency. Now an independent entity, the company delivers over 400,000 market quotes daily, providing more than 400% greater coverage than reported trades alone. Our platform already powers intraday pre-trade data, hourly municipal benchmark curves (including the Muni Benchmark Curve, Investment Grade Credit Curves, and Insured Spread Curves), peer bond comparisons built on logistic regression analysis of yield and municipal bond spreads, Best Execution and Markup compliance tools, and the University of Chicago Indices. MBIS's market data also drives SQX's evaluated municipal bond pricing,

For firms already familiar with MBIS through its municipal bond yield curve data, muni bond search tools, or municipal bond CUSIP lookup, this reference data offering adds a critical new dimension to a platform they already depend on.

What the Dataset Includes

The MBIS muni reference data feed spans 17 tables covering the full lifecycle of a municipal bond. Core bond information lives in Bond Offering Details, Bond Additional Details, and Issue Details, providing the foundational identifiers, terms, and attributes for each security and its associated issue. For callable municipal bonds, Call Schedule and Redemption Details tables cover optional and mandatory call provisions, refundings, and related redemption activity. Firms tracking muni bond default rates will find the Issue Default Summary table particularly valuable, with fields for default dates, types, event triggers, resolution status, and reinstatement history.

Variable rate municipal bonds get dedicated coverage through three tables (Profile, History, and Schedule) capturing instrument types, rate formulas, reset frequencies, benchmarks, and historical rate data. Additional tables address Sinking Fund Details, Partial Redemption Activity, Put and Tender Schedules, Coupon History, Additional Credit Details, and a full Agent Directory with addresses and issue-level agent roles.

Output files use a pipe-delimited format with standardized date formatting for clean integration. If you’re interested in complete field-level documentation, our product page has all the details.

Why It Matters Now

Record municipal bond issuance means more securities to track, more data to manage, and more places for gaps to create operational risk. Compliance requirements keep tightening. It doesn’t help that historical providers of this data are shifting their policies. Municipal bond funds and municipal bond index providers need clean, comprehensive inputs to build and maintain their products. MBIS brings a credible, infrastructure-backed option from a provider that already understands what muni professionals need.

Get Started

With issuance volumes at record highs and the 2026 municipal bond outlook pointing toward continued growth, reliable bond reference data has never been more critical. MBIS's 17-table dataset, built on proven market infrastructure and delivered through established partnerships with SQX and EDI, is designed to meet that need.

MBIS Data Powers New Municipal Bond Indices at the University of Chicago

Beginning October 2022, Municipal Bond Information Services ( MBIS ) will supply data for the Center for Municipal Finance at the University of Chicago. The Center is part of the University of Chicago’s Harris School of Public Policy, whose mission is to bring empirical, data-driven research to policy studies. MBIS CEO Tim Tatum commented, “It has been a pleasure to work with and support the Harris School in the area of municipal bonds and public finance.”

MBIS data will power the online indices for cities, counties, and school districts , part of the Center’s Data Dashboard. According to Wesley Janson, a graduate student working on the project, "MBIS was the only place we could get comprehensive enough data for us to create this index. Because of their robust historical trading data, we were able to create an accurate measure of market sentiment towards some of the largest municipal bond issuers.”

The Data Dashboard aligns with the Center’s mission to promote engagement with the financial issues faced by state and local governments both in the U.S. and globally. Janson explained, "These municipal bond indices are the backbone of our data dashboard, offering timely information to journalists, researchers, issuers, and investors. We aim to be the one-stop shop for all things municipal finance."

Data from the Center’s indices have already appeared in reporting by Bloomberg and Crain’s Chicago Business .

MBIS aggregates and delivers over 400,000 pre-trade bids wanted and offering daily, giving the largest set of data available today. The company was founded as a consortium of eleven municipal security trading firms who assembled to aggregate their market data.

MBIS supplies data for University of Chicago Center of Municipal Finance.

MBIS data reveals muni price trends through times of crisis

We at MBIS are extremely pleased to be a data supplier for the University of Chicago Center for Municipal Finance.

MBIS bond data powers the Center's Indices for general obligation bonds for cities, counties, and school districts , providing a robust set of characteristics and prices that track bids, offers, and trades on a real-time basis. The following graph of US City General obligation bonds shows a base start of 100 starting on January 2, 2018:

As you can see, there are quite a variety of price moves among the US large cities, from the arrival of Covid concerns in the spring of 2020 where there was a sizable drop in prices, to the steady recovery through 2021. Then the extreme hit to bond prices as rates rose from the Federal Reserve raising rates in large increments of 75 basis points during 2022. Inflation threats, Ukraine, rising energy prices all have hit the economy in both equities and bonds.

The next graph of counties shows similar price movements for the same reasons.

The final graph of school districts also tells the same story.

Our data is uniquely suited for revealing these sorts of trends. Our comprehensive universe of pre-trade bid and offer data gives a powerful tool for fine-grained analysis to both academic and market users alike.

MBIS data is available via the MBIS.com website, managed by SQX, Securities Quote Xchange .
