NUMI vs SCMB

NUMIBNuveen Municipal Income

SCMBASchwab Municipal 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%.

SCMB Schwab's take on the core muni sleeve: three basis points, thousands of AMT-free bonds from across the country, and a monthly distribution. Bottom-of-the-table pricing, no frills attached.

Stated mandate

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

SCMB The fund seeks to track, before fees and expenses, the total return of an index representing the U.S. AMT-free municipal bond market.

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.

• SCMB Three basis points a year, against a 0.30% median for muni bond funds. Among the top-graded names in the category, only Vanguard's VTEB matches that fee.
• Follows the ICE AMT-Free Core U.S. National Municipal Index across thousands of bonds and issuers, so no single borrower or state drives the portfolio.
• Plain passive plumbing done well: it stays close to its index, trades actively, and pays monthly. One of the stronger implementations in the muni aisle.

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.

• SCMB Launched in 2022, so its live record is shorter than muni staples like MUB and VTEB, even though the strategy is the same broad-market idea.
• Bond math still applies. This is a portfolio of municipal bonds, so share prices move opposite to interest rates.
• National in scope, not single-state like NYF, so it is not built around any one state's tax rules.
