What’s at Stake in the 2026 Midterms for Municipal Bonds

The U.S. municipal bond market, worth almost $600 billion, could see a dramatic shift as the midterm elections approach. State‑level tax reform referendums and new bond‑issuance approvals are the key variables that will shape yields and supply‑demand dynamics, according to market observers.

How the Elections Could Tilt the Tax Landscape

In California, voters will decide on a “billionaire tax” that would impose a one‑time 5% levy on assets over $1 billion, and a measure to make permanent a temporary tax increase on high earners earning more than $371,000 annually. Washington state is holding a referendum on whether to abolish the 9.9% tax on high earners with incomes above $1 million. Florida is pushing a measure to expand the homestead property‑tax exemption limit to a maximum of $250,000 over the 2027‑2028 period.

Dan Close, head of municipal bonds at Nuveen, said the elections are likely to widen the tax‑policy gap between Democratic‑leaning (blue) states and Republican‑leaning (red) states. “We’re seeing complete polarization between red states and blue states,” he explained. “Blue states are introducing progressive income‑tax structures to secure more revenue from high earners, while red states are pursuing property‑tax cuts to ease inflationary pressures.”

Bond Issuance Momentum and Supply Concerns

According to the Securities Industry and Financial Markets Association (SIFMA), municipal bond issuance through September this year reached $473.8 billion, up 7.8% year‑over‑year. Last year’s annual issuance was $587.3 billion, a 14.3% increase from the previous year.

Cooper Howard, director of fixed‑income research and strategy at Charles Schwab, warned that supply volume will be the biggest issue after the election. “Issuing entities have the flexibility to issue bonds over several years,” he said. Tom Kozlik, head of municipal strategy at Hilltop Securities, added that property‑tax cuts won’t necessarily lead to credit‑rating downgrades, but balancing work will be needed in terms of overall tax revenue. He recommends focusing on bonds rated AA or higher, given the attractive current yields.

Why This Matters for Investors

Tax‑exempt municipal bonds are likely to become even more valuable as the tax‑policy divide deepens. Investors are expected to seek refuge in the municipal bond market, which could push bond prices higher and yields lower. The shift could also affect the mix of issuers and the types of projects funded, as state and local governments adjust to new revenue realities.

Key takeaways for investors:

• Watch election outcomes in California, Washington, and Florida for immediate tax‑policy changes.
• Monitor new bond‑issuance approvals post‑election to gauge supply pressure.
• Focus on high‑quality issuers (AA+ and above) to mitigate credit‑risk concerns.
• Consider the potential for lower yields as demand for tax‑exempt securities rises.

What to Watch Next

The next few weeks will be critical as voters head to the polls. Market participants should track:

1. The results of the California billionaire tax and high‑income tax measures.
2. Washington’s referendum on the 9.9% high‑income tax.
3. Florida’s homestead property‑tax exemption expansion.
4. Any new bond‑issuance approvals announced by state and local governments.

These developments will shape the supply‑demand balance and the tax‑exempt value proposition that drives municipal bond pricing.
