VTEBAVanguard Tax-Exempt Bond ETF

In short

NMB Most national muni ETFs are cheap index trackers. NMB goes the other way: an actively managed muni portfolio run by credit specialists, with an options-selling sleeve stacked on top for extra income.

VTEB Vanguard's national muni index fund, running since 2015 at three basis points, a tenth of what the typical muni ETF charges. Its benchmark screens for investment-grade bonds whose income is exempt from federal tax and the AMT.

Stated mandate

NMB The fund’s current stated objective is to maximize total return.

VTEB VTEB seeks to track an index measuring the investment-grade segment of the U.S. municipal bond market. It uses passive sampling to approximate the index and generally invests in federally tax-exempt municipal securities.

Why people hold it

• NMB Two income engines in one wrapper: tax-free muni coupons plus a risk-managed options-selling strategy that writes spreads across equity, bond and commodity indices and ETFs.simplify.us
• Sub-advised by Foundation Credit, a specialist credit firm, hunting the fragmented muni market for bonds that passive index mandates leave behind.simplify.ussimplify.us 2
• Holds mainly investment-grade municipals with no set duration limits, so the managers can roam the curve instead of matching an index's maturity profile.simplify.ussimplify.us 2

• VTEB Three basis points a year against a 0.30% muni-ETF median. On tax-exempt bonds, where coupons are modest, that fee gap is a real slice of the payout.
• The index holds only investment-grade munis whose interest is exempt from federal income tax and the alternative minimum tax, so the income carries no AMT surprise.vanguard.com
• A multi-billion-dollar fund and one of the most heavily traded in the muni category, which tends to show up as tight bid-ask spreads. Income is paid monthly.
• It has tracked its benchmark closely and sits among the strongest implementations in a crowded muni bond peer group.

Worth knowing

• NMB Costs 0.52% a year against a 0.30% median for national muni funds. That is the price tag on active management plus the options overlay.
• The options income and opportunistic trading gains are taxable, so the payout is not purely tax-exempt the way a plain index muni fund's is.simplify.us
• A small, lightly traded fund launched in 2024, holding roughly 70 bonds, with distributions that have not followed a fixed calendar.

• VTEB Federal exemption, not blanket coverage. Income can still be taxable in your home state, which is why single-state funds like NYF exist alongside it.vanguard.com
• Credit quality is investment grade, so rates are the main swing factor: when muni yields rise, bond prices and the fund's share price fall.vanguard.com
• Sampling, not full replication. The fund owns a representative slice of a very large index rather than every bond in it.vanguard.com
