If you have been parking cash in a savings account and calling it a strategy, there is a corner of the market quietly paying more than your bank.
Municipal bonds, the debt issued by states, cities, and school districts, are offering yields that have crept up to levels not seen in roughly a decade.
For savers in higher tax brackets, the math can get interesting fast.
The interest on muni bonds is generally exempt from federal income tax, and often from state tax too if you buy bonds from your home state.
That tax break means a 4% muni yield can feel like 5% or 6% from a taxable bond once you run the numbers.
The catch is that munis are not a savings account with a nicer font.
They are loans to governments, and governments can run into trouble.
Some cities have restructured their debt, and bondholders have taken haircuts.
The risk is real, even if it is lower than what you would see in a shaky corporate bond.
The Federal Reserve's rate hikes pushed borrowing costs across the board higher.
At the same time, banks and insurers, two of the biggest traditional buyers of munis, have pulled back.
Fewer buyers means issuers have to offer more interest to attract money.
If you want in, you almost never buy individual bonds directly.
Most people access munis through mutual funds or ETFs that hold a basket of them.
That spreads your risk across hundreds of issuers instead of betting on one city's budget.
The trade-off is that fund prices move around, so your "safe" investment can still dip on paper.
A fund charging 0.75% a year on a 4% yield is handing a big chunk of your return to the manager.
Index muni funds often charge a fraction of that.
Also check whether the fund holds bonds from your state if you want the state tax break, because a national fund will not give you that.
One more thing to know: muni bonds are not for money you might need next month.
If rates rise after you buy, the resale value drops.
If you sell early, you can lose principal.
Plan to hold for years, or stick with a short-term fund if you want less drama.
There is also a tax wrinkle that trips people up.
Even though the interest is federal-tax-free, it still counts toward your income when the government calculates taxes on your Social Security benefits.
That can nudge some retirees into a higher taxable bracket without them realizing it.
For anyone in the 22% bracket or below, the tax advantage is modest, and a high-yield savings account or Treasury might serve you just as well.
For people in the 32% bracket and up, especially in states with income tax, the case gets a lot stronger.
My take: muni bonds deserve a look, but not a blind one.
Run your own after-tax math, keep an eye on expense ratios, and treat this as money you will not touch for a while.
Final Thoughts
If the numbers work, the tax break is doing real work for you.
