Municipal bonds, the boring corner of investing where cities and school districts borrow money, are suddenly offering yields that would have seemed absurd five years ago.
Top-rated 10-year munis are paying north of 3%, and longer maturities are flirting with 4%—levels not seen since before the Fed started cutting.
For savers burned by sub-1% savings accounts, that's catnip.
Here's the sales pitch you'll hear from brokers: muni interest is usually exempt from federal income tax, and often from state tax too if you buy bonds from your home state.
For someone in the 32% bracket, a 3.5% tax-free yield is worth about 5.1% taxable.
That math is real, and it's why money has been flooding into muni funds.
But the pitch conveniently skips a few things.
If a city's pension obligations blow up or a hospital system defaults, bondholders can absolutely lose money—just ask anyone who held Puerto Rico debt or, more recently, bonds from distressed retirement communities in Florida and California.
If you need to sell before maturity, you may get quoted a price several percentage points below what you paid, especially in a stressed market.
The spread between what dealers buy at and sell at is often wide enough to erase a year of interest.
If you buy a 20-year bond at 4% and rates rise to 5%, the resale value drops sharply.
You can hold to maturity and get your money back, but your cash is locked up.
That's fine if you have a 20-year horizon—less fine if you're 70 and might need it for a roof.
A muni bond ETF or mutual fund pays monthly distributions, but the share price moves daily.
Investors who chased high yields in 2021 watched NAVs sink for two straight years.
The yield was real; the principal shrinkage was also real.
Some advisors charge 1% to manage a muni portfolio that yields 3.5%.
That's nearly a third of your income gone before taxes even enter the picture.
Commission-based purchases can carry markups of 1% to 2% baked into the price, which you'll never see on a statement.
If you're in the 12% bracket, a taxable Treasury or high-yield savings account may net you more after tax than a muni, with less risk and instant liquidity.
Munis are a tool for high earners in high-tax states, not a universal upgrade.
So who benefits from the current enthusiasm?
Brokerages collecting markups, fund companies collecting expense ratios, and financial advisors collecting assets under management.
The bonds themselves are neither villain nor hero—they're just loans with terms you need to read.
If you're considering munis, start by asking what your actual marginal tax rate is, how long you can truly leave the money alone, and whether you're buying individual bonds or a fund.
If a salesperson can't answer those three questions clearly, walk away.
Final Thoughts
Higher yields are only a gift if the risk fits your life—otherwise they're just a prettier way to tie up money you might need.
