NUMI vs VTEB

NUMIBNuveen Municipal Income

VTEBAVanguard Tax-Exempt Bond ETF

In short

NUMI Nuveen underwrote its first municipal bond in 1898. NUMI packs that credit desk into an ETF: roughly 300 mostly investment-grade munis, tilted long, hunting undervalued yield, and paying tax-exempt income monthly for 0.30%.

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

NUMI The Fund invests at least 80% of its net assets in municipal securities whose interest is exempt from federal income taxes.

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

• NUMI Active, not an index sweep: roughly 300 bonds, primarily investment grade with room for higher-yielding and undervalued names, at a weighted average maturity above 10 years.nuveen.com
• At least 80% of net assets sit in municipal bonds whose interest is exempt from federal income tax, and distributions go out monthly.
• Gross and net fees match at 0.30%, so there is no fee waiver due to roll off and lift the cost later. That lands near the muni category's typical fee.

• 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

• NUMI Index rivals charge a fraction: VTEB and SCMB at 0.03%, MUB at 0.05%. The 0.30% here pays for a credit desk picking bonds rather than broad market coverage.
• Long bonds move hard when rates move. The fund concentrates in long maturities and durations, and its own materials flag interest rate, duration and call risk.nuveen.com
• Launched January 2025, it is still a smaller, thinly traded fund, so the spread at the point of trade is worth a look.

• 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
