BMOP vs SCMB

BMOPCBNY Mellon Municipal Opportunities ETF

SCMBASchwab Municipal Bond ETF

In short

BMOP A 2008-vintage muni strategy that reached the ETF market the long way: it ran for years as a BNY Mellon mutual fund before reorganizing into this ETF in January 2026. Still actively managed, still hunting mispriced bonds across the muni market.

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

BMOP The ETF seeks total return through high current income exempt from federal income tax and capital appreciation.

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

• BMOP Active by design: the team uses fundamental credit work and relative value to trade across muni sectors, and can overweight a sector it judges cheap.bny.com
• The mandate is plain: high current income exempt from federal income tax plus capital appreciation, spread across roughly 700 municipal bonds.
• Not a startup fund. The strategy dates to 2008 as the BNY Mellon Municipal Opportunities Fund and carried those operations into the ETF at the January 2026 reorganization.bny.com
• Size counts in a dealer-quoted market like munis: this is a multi-billion-dollar, moderately traded fund rather than a thin new listing.

• 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

• BMOP You pay for the active seat: 0.49% net of a waiver through December 31, 2027 (0.54% gross), above the category median, next to index peers VTEB at 0.03% and MUB at 0.05%.
• No index to fall back on. Results follow the team's sector and credit calls, not the Bloomberg U.S. Municipal Bond Index used as its broad benchmark.bny.combny.com 2
• The exemption the fund targets is federal income tax. State and local taxes can still apply to what you collect.

• 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.
