Investors whipsawed by current events and persistent economic uncertainty are doing what investors have done for generations: Piling into municipal bonds.

In the first four months of 2026, municipal funds have attracted approximately $22.3 billion of net inflows, the biggest surge for the time period in five years.

While the municipal market experienced turbulence after the Middle East war started, investors have since flocked to state and local debt.

“Even when there was a lot of volatility in March, the investor base saw our asset class as a safe haven, and on top of that as a place of attractive yield,” a muni market analyst told Bloomberg. “Our calendar hasn’t really let up despite the volatility and it is speaking to this very strong investor demand that does not seem to be abating.”

Dependability of income

Market professionals cite various factors for the surge in municipals – higher yields, the relative stability of munis during geopolitical conflict and ongoing questions surrounding inflation and interest rates.

Another factor may be today’s elevated stock market valuations and the relatively modest income many stocks currently provide.

Recently, the dividend yield on the S&P 500 stood at just 1.1%, according to Reuters, barely above the lowest level in 50 years and the lowest since 2000. The unusually low yield reflects strong stock-price gains and the market’s continued emphasis on growth over income.

Reuters noted that such low dividend yields “certainly suggest that U.S. equities are pricing in a lot of optimism,” adding that the last time yields were this low was during the dot-com era.

That does not necessarily mean stocks are headed for trouble. But it may help explain why some investors are increasingly focused on balancing growth-oriented investments with the dependable income and stability that municipal bonds offer.

Yields and value

At the same time, municipal bond yields are near years-long highs.

Recently, the taxable-equivalent yield on 30-year, AAA-rated munis was a compelling 7.26% for investors at the 40.8% tax rate.

Another widely followed measure of value is the muni-to-Treasury ratio, which compares municipal bond yields to Treasury yields of similar maturities. Historically, higher ratios have often indicated better relative value for municipal bonds.

Recently, the 30-year muni-to-Treasury ratio stood at 86%, a level market professionals regard as appealing.

“In plain English, munis are cheap relative to Treasuries right now, and history suggests that when ratios get elevated like this, it has tended to be a favorable time to add exposure,” VanEck reported recently.

Credit quality

Importantly, municipal bond price fluctuations earlier this year have largely reflected changing interest-rate expectations more than weakening credit quality, as we have noted (“What Long-Term Muni Investors See”).

VanEck observed that state and local tax collections in many key states remain more than 10% above prior levels, supporting the overall financial health of many municipal issuers.

In other words, many analysts believe the recent market volatility has been driven more by interest-rate concerns than by concerns about issuers’ ability to meet their obligations.

“It means you’re not being asked to take on additional credit risk to capture this opportunity. You’re simply being offered better prices on the same high-quality bonds because the broader rate environment moved against them,” VanEck said.

A peaceful night’s sleep

In times of uncertainty, investors are drawn to the historically lower volatility of high-quality municipal bonds and, of course, the steady stream of tax-exempt income.

Investors holding individual bonds can take comfort in reaping a defined stream of interest payments and a known maturity date.

For years, many investors focused on one central question: How much growth can I get?

Today, there’s more focus on a second question: How much uncertainty do I really want?

For longtime muni investors, balancing growth with dependable income and unusual value is nothing new.
