Municipal bonds have quietly turned into one of the better-paying corners of the bond market, with yields on high-grade, long-dated munis recently sitting near their highest levels in over a decade.
For savers burned by years of near-zero rates, a tax-free yield in the 4% to 5% range sounds like found money.
But before you move your emergency fund into someone else's sewer project, it's worth asking who is selling these bonds to you and why they're suddenly so generous.
Start with the tax math, because that is the entire pitch.
Munis are exempt from federal income tax, and often from state tax if you buy bonds from your home state.
A 4% tax-free yield is roughly equivalent to a 5.3% taxable yield for someone in the 24% bracket, and closer to 6.7% for a top-bracket earner.
If you're in a low tax bracket, that same bond is a mediocre deal compared to a Treasury or a plain CD.
The advantage shrinks fast as your income falls, which is exactly why muni marketing tends to be aimed at people who don't need the pitch.
Cities, states, hospitals, and school districts issue munis to build things, and when interest rates rose, many of them pulled back on new borrowing.
Fewer new bonds plus steady demand from wealthy investors and funds pushed prices around, and yields climbed as the market repriced.
It's a market adjusting, and the people arranging these deals earn fees whether or not the bond works out for the buyer.
Then there's the part the brochures gloss over: credit risk. "Municipal" sounds like a government guarantee.
General obligation bonds are backed by a taxing authority; revenue bonds are backed by a specific project, like a toll road or a hospital system, and those can and do go sideways.
Puerto Rico's long default is the loudest recent reminder.
Defaults are rare, but rare is not never, and when they happen the losses can be ugly and slow to resolve.
If you need to sell before maturity, you may get a price that makes you wince, especially if rates have moved against you or if a headline has spooked the market.
Funds and ETFs solve that problem but introduce price swings, and a bond fund is not a bond, no matter how the sales copy reads.
Your principal can wobble in ways a hold-to-maturity buyer never sees.
If you're a high earner in a high-tax state with money you genuinely won't need for years, a ladder of high-grade munis or a low-cost national fund can make sense.
If you're chasing yield because your savings account feels boring, this is not the trade.
Read the offering statement, check the credit rating, understand whether the bond is general obligation or revenue-backed, and know the call features that can hand your bond back early.
The current yields are real, and for the right buyer they're genuinely attractive.
They're also a symptom of a market that got more cautious about borrowers, not a sign that someone is doing you a favor.
