View Membership BenefitsIn this higher-for-longer rate regime, municipal bonds have emerged as a prime go-to option. Elevated interest rates have investors scrambling for yield, and munis have been ready to answer the call with tax-exempt income. This greater demand for munis comes after sitting on the sidelines for many years. Now, high-earning investors are returning to the asset class to capture competitive, risk-adjusted yields across the full spectrum of the muni curve.
Key Takeaways:
- In this higher-for-longer rate environment, municipal bonds have resurfaced as a premier vehicle for tax-exempt income, capturing $105 billion in trailing 12-month net inflows while delivering attractive tax-equivalent yields.
- While municipal credit fundamentals remain strong following state tax revenue growth and pandemic reserve accumulation, market segmentation requires caution around higher-risk revenue bonds and long-term pension liabilities.
- Investors can access this market through Northern Trust's core low-cost strategy (TAXT) or its innovative tax-exempt distributing ladder ETFs (MUNJ, MUNF, MUNG, MUNH), which distribute maturing principal annually alongside income to optimize cash flow planning.

Yield and Appreciation in the Muni Market
As mentioned, this yield story wasn't an overnight phenomenon. As Forbes explained, it's a narrative that was 15 years in the making. When the Federal Reserve anchored short-term rates near zero, muni yields were so low that even their federal tax exemption barely covered the gap against taxable fixed income options. In the current market backdrop, the federal funds rate is holding steady within the 3.50% to 3.75% range. That said, tax-exempt bonds are once again delivering competitive after-tax returns, especially when it comes to high-earning investors.
As Forbes expertly pointed out, comparing munis to yields in other corners of the bond market requires closer scrutiny. It all comes down to taxable-equivalent yield, which is the pretax return a taxable bond must deliver to match a tax-free municipal yield. For those sitting in the top federal bracket, a municipal bond yielding 4.0% is equivalent to a taxable corporate bond yielding roughly 6.6%. When factoring in state income taxes for residents buying in-state bonds, the taxable-equivalent yield can be even higher, rivaling investment-grade corporate credit sans the additional corporate default risk. This is especially pertinent in high-tax jurisdictions like California, New York, or New Jersey.
Additionally, muni funds have demonstrated remarkable strength. Morningstar noted that their Morningstar US Municipal Bond Index gained 5.5% over the one-year period through July 2026, outpacing most major fixed income benchmarks. In turn, investors responded by pouring approximately $105 billion into municipal ETFs and mutual funds over the trailing 12 months through June 2026.
Strong Credit Fundamentals, But Risks Abound
A common notion is that greater yields mean greater credit risk, but underpinning this market surge for munis is a solid credit foundation. Forbes also noted that state and local government balance sheets emerged from the post-pandemic period in exceptional shape. Federal relief funds, combined with strong tax revenue growth from resilient employment and property values, allowed municipalities to build historically large reserve funds. As a result, rating agency upgrades have consistently outpaced downgrades across the municipal universe.
However, the muni market isn't homogeneous as credit quality remains highly segmented. While general obligation bonds backed by broad taxing authority sit at the safer end of the spectrum, revenue bonds tied to specific hospital systems, toll roads, or project financings can carry greater operational risk. Furthermore, long-term liabilities like underfunded state pension systems continue to weigh on specific issuers.
This dispersion within the muni market has tempted some investors to chase high-yielding strategies that achieve outsized returns by taking on greater credit and duration risk. While these aggressive strategies thrive during market rallies, they have historically suffered severe drawdowns during municipal selloffs along with elevated volatility. This underscores the need for disciplined risk controls when adopting this yield-chasing strategy.
Structural Opportunities and Implementation
Knowing the inherent risks involved, the municipal market’s structure creates unique opportunities. For investors seeking efficient entry points into this rewarding yet nuanced municipal market, Northern Trust Asset Management offers both broad-market core strategies and targeted structural innovations.
For broad exposure, the Northern Trust Tax-Exempt Bond ETF (TAXT) seeks to track the ICE All Maturity Focused Municipal Bond Index, providing passively managed investment-grade exposure across the full municipal yield curve. TAXT is also a cost-effective option as well with an expense ratio of just five basis points.
Additionally, building an individual municipal bond ladder offers predictable tax-exempt income and a guaranteed return of principal at maturity. However, constructing a properly diversified ladder across issuers and sectors requires substantial capital due to market fragmentation. ETFs can solve this liquidity and diversification challenge by offering broad exposure at lower costs with distributing ladder options. That said, Northern Trust expanded its distributing ladder suite last month by launching four new tax-exempt municipal ladder ETFs:
With a competitive net expense ratio of 18 basis points, these funds utilize a defined-maturity structure where each portfolio rung holds bonds maturing in a specific calendar year. Unlike traditional bond ladder funds that reinvest maturing principal into future rungs, these distributing ladder ETFs pay out principal annually alongside regular distributions, providing structured, tax-exempt cash flows tailored for long-term income and retirement planning.
