U.S. Municipal Bond Market Preview: Week of September 15, 2025
The Week Ahead
The U.S. municipal bond market is poised for a dynamic week starting September 15, 2025, as investors brace for a combination of new issuance activity, key economic data releases, and evolving policy narratives. The primary market is expected to see a moderate uptick in volume, with approximately $8-10 billion in new deals slated to come to market, driven by infrastructure and general obligation financings. Secondary market activity will likely remain influenced by ongoing volatility in U.S. Treasury yields, with particular attention on the Federal Reserve’s latest signals regarding interest rate policy. Additionally, market participants will monitor state and local budgetary pressures amid inflationary concerns and potential federal funding updates, which could impact credit quality perceptions for certain issuers.
Municipal Bond New Issuance Calendar
The new issuance calendar for the week features several notable deals across diverse sectors and regions, reflecting a mix of competitive and negotiated sales. Below are some of the major offerings, including specific deals from requested states where applicable:
- Texas: The Texas Water Development Board is expected to issue approximately $500 million in revenue bonds to fund statewide water infrastructure projects. This deal, rated AA+ by major credit agencies, will be a negotiated sale with a prominent national bank as lead underwriter and a well-known municipal advisor guiding the transaction. The structure includes serial maturities ranging from 5 to 30 years, targeting institutional buyers seeking stable, long-term yields.
- New Jersey: The New Jersey Turnpike Authority plans to bring $400 million in toll revenue bonds to market, rated A+ due to strong traffic projections and toll collection stability. This competitive sale will test investor appetite for transportation-related debt, with maturities structured over a 10- to 25-year horizon, appealing to both retail and institutional investors.
- Tennessee: The Tennessee State Funding Board is scheduled to issue $300 million in general obligation bonds, carrying a AAA rating reflective of the state’s strong fiscal management. This negotiated deal, led by a consortium of regional underwriters and supported by a national municipal advisor, features a mix of short- and long-term maturities to refinance existing debt and fund capital projects.
- Nevada: Clark County, Nevada, anticipates pricing $250 million in airport revenue bonds for Las Vegas McCarran International Airport expansion projects. Rated A, this negotiated sale will be managed by a leading investment bank with a focus on institutional demand. The structure includes callable bonds with maturities extending to 2040, offering flexibility amid tourism-driven revenue projections.
Other significant deals include a $600 million general obligation offering from a major California school district (competitive) and a $350 million hospital revenue bond from a Midwest healthcare system (negotiated), both rated in the A to AA range. The diversity of sectors—education, transportation, healthcare, and utilities—underscores the broad appeal of municipal debt this week, though competitive sales may face pricing pressure if demand softens.
Municipal Market Data
Using publicly available Municipal Market Data (MMD) benchmarks as a reference, current yield curves suggest a relatively steep trajectory for tax-exempt bonds as of early September 2025. The 10-year AAA MMD yield stands at approximately 3.25%, while the 30-year benchmark hovers near 3.85%, reflecting expectations of sustained inflation and potential rate hikes. Week-over-week changes in MMD yields could be influenced by Treasury market movements, with a 5-10 basis point upward shift possible if economic data surprises to the upside. Spreads between AAA and lower-rated (BBB) municipal bonds remain widened at around 80-100 basis points for longer maturities, signaling ongoing credit risk differentiation. Investors should monitor daily MMD updates during the week of September 15 to assess pricing trends for new issues and secondary trades.
Municipal Bond Market Sentiment
Market sentiment entering the week appears cautiously optimistic, with trading flows indicating steady demand for high-quality paper but hesitancy around lower-rated credits. Secondary market performance has been mixed, with longer-duration bonds underperforming due to yield curve steepening and rising Treasury rates. Dealer inventories are reported to be lean, suggesting limited supply pressure in the near term, though some desks may look to offload positions ahead of new issuance. Institutional buyers, including mutual funds and insurance companies, continue to dominate bid lists, while retail demand remains tepid, particularly for bonds with maturities beyond 10 years. Technical factors, such as reinvestment needs from maturing bonds and coupon payments, could provide a tailwind for demand mid-week.
Policy & Legislative Context
On the policy front, municipal bond investors are closely watching developments in federal tax law and infrastructure funding. Discussions in Congress regarding potential extensions or modifications to tax-exempt bond provisions could influence market dynamics, particularly if advance refunding capabilities are revisited. Additionally, the rollout of federal infrastructure grants under existing legislation continues to bolster credit profiles for certain issuers, especially in transportation and water sectors. Meanwhile, Federal Reserve commentary on monetary policy tightening remains a critical overhang, as higher borrowing costs could strain state and local budgets, potentially impacting debt service coverage for weaker credits.
Macro-Economic Context
The macroeconomic backdrop for the week of September 15, 2025, includes several pivotal data releases that could sway tax-exempt yields and investor demand. Key among them is the monthly Consumer Price Index (CPI) report, expected mid-week, which will provide fresh insight into inflation trends. A higher-than-expected CPI reading could push Treasury yields upward, exerting parallel pressure on municipal bond yields and dampening demand for longer maturities. Additionally, retail sales data and industrial production figures, also due this week, will offer clues on consumer spending and economic growth, potentially influencing risk sentiment. With the Federal Reserve’s next policy meeting on the horizon, markets will parse every data point for indications of future rate hikes, which could further shape yield expectations in the municipal space.
Conclusion
The week of September 15, 2025, presents a multifaceted landscape for municipal bond market participants, with new issuance opportunities, economic data catalysts, and policy developments all in play. Investors are advised to remain vigilant on yield movements, credit spreads, and macroeconomic signals while evaluating new deals and secondary market positioning. As always, a disciplined approach to risk assessment and portfolio diversification will be key to navigating potential volatility.
