BMOP vs VTEB

BMOPCBNY Mellon Municipal Opportunities ETF

VTEBAVanguard Tax-Exempt 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.

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

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

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

• 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.

• 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

• 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.

• 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
