Municipal bond yields have climbed to levels that would have seemed implausible just a few years ago, and most Americans are ignoring one of the better income opportunities in plain sight.
The national average yield on top-rated 10-year muni bonds recently hovered in the 3% to 3.5% range, with longer maturities touching 4% or more in some states.
That's a dramatic jump from the near-zero era, when these bonds paid barely enough to cover a cup of coffee.
Municipal bond interest is generally exempt from federal income taxes, and if you buy bonds from your home state, you often dodge state and local taxes too.
That tax-free status means a 3.2% muni yield can be worth far more than a 4% taxable corporate bond once the IRS takes its cut.
If you're in the 24% federal bracket, a 3.2% tax-free yield equals roughly a 4.2% taxable yield.
Bump up to the 32% bracket and the same bond behaves like a 4.7% taxable investment.
For high earners in states with their own income taxes, the effective advantage stretches even wider.
The higher your tax bracket, the more a muni's tax exemption is worth to you.
Demand has been strong all year, driven partly by retirees and near-retirees hunting for reliable income.
Supply has been steady but not overwhelming, which has kept prices from cratering.
When yields rise, prices on existing bonds fall, so buyers stepping in today are locking in better terms than anyone who bought two years ago.
That's a rare spot for income investors to be in.
The catch is that munis aren't risk-free, despite their reputation for safety.
Individual bonds carry default risk, especially if a city or state runs into fiscal trouble, and bond funds can lose value when interest rates move against them.
If you might need the money within a year or two, a long-dated muni fund is a bad fit, because a rate spike could leave you selling at a loss.
Some smaller issues trade thinly, and selling before maturity can cost you more than you expect.
If you want in, the simplest route is a low-cost municipal bond exchange-traded fund or mutual fund, which spreads your money across hundreds of issuers.
That diversification matters, because betting on a single city's finances is a gamble most households shouldn't take.
For those who want to pick individual bonds, buying through a brokerage and holding to maturity lets you sidestep price swings entirely, as long as the issuer keeps paying.
Pay attention to a few numbers before you buy.
Check the yield to maturity, not just the coupon rate, since that reflects what you'll actually earn if you hold the bond to the end.
Look at the credit rating and whether the bond is insured.
And confirm the tax treatment, because some munis are taxable, including certain "private activity" bonds and any bond bought at a premium or discount.
If your tax-free 3.2% yield doesn't keep pace with rising prices, you're treading water in real terms even as your statement looks fine.
Munis work best as a piece of a broader plan, not as a magic bullet for income.
Our take: municipal bonds deserve a serious look right now for anyone in a higher tax bracket who wants steadier, tax-advantaged income.
Just don't chase yield into shaky credits or lock up money you might need soon.

The opportunity is real, but so are the trade-offs.
