SUB vs VTES

SUBAiShares Short-Term National Muni Bond ETF

VTESAVanguard Short-Term Tax-Exempt Bond ETF

In short

SUB Munis, but only the near end of the curve. Since 2008 SUB has tracked an AMT-free index of investment-grade municipal bonds maturing inside five years, paying tax-exempt income monthly with far less rate sensitivity than long-dated muni funds.

VTES Vanguard's muni ETF on a short leash: an AMT-free tax-exempt index, but capped at seven years to trim interest-rate sensitivity. Five basis points, roughly 2,700 bonds, income paid monthly.

Stated mandate

SUB The fund seeks to track an index of short-term, investment-grade U.S. municipal bonds maturing from one month through five years, providing tax-exempt income while managing interest-rate risk.

VTES The Fund seeks to track an index representing investment-grade U.S. municipal bonds with remaining maturities from one month through seven years.

Why people hold it

• SUB Charges 0.07% a year against a category median near 0.30%. On tax-exempt bond income, that fee gap is a meaningful slice of what actually reaches you.
• Two dials set on purpose: maturities from one month to five years, and an AMT-free index, so neither rate swings nor the alternative minimum tax hit the same way.ishares.com
• A multi-billion-dollar fund running since 2008 under iShares, with tight tracking of its ICE benchmark. One of the sturdier implementations in the muni group.
• Pays monthly, so the tax-exempt income arrives on a regular cadence rather than in quarterly lumps.

• VTES Costs 0.05% a year, a fraction of what the typical muni-bond fund in its category charges. One of the cheapest ways into tax-exempt bonds.
• Maturities run one month to seven years, so the portfolio moves less on rate swings than long-dated muni funds. Short duration is the whole point here.vanguard.com
• The index is AMT-free national investment-grade munis, so interest is federally tax-exempt and not caught by the alternative minimum tax.vanguard.com
• Roughly 2,700 bonds via index sampling, run by Vanguard's fixed income group, with distributions paid monthly. It tracks its benchmark closely.vanguard.com

Worth knowing

• SUB The five-year ceiling is the whole design, and it cuts both ways: less rate sensitivity, but a shorter stretch of the curve to draw income from than full-maturity muni funds.
• This is a national portfolio. Single-state funds like NYF chase a home-state tax break that a nationwide muni basket cannot offer.
• Broad-maturity peers VTEB and SCMB run at 0.03%. The short-end tilt here costs a few basis points more.

• VTES Short maturities cut both ways. Vanguard's own materials describe moderate current income, the trade-off for less rate sensitivity than longer muni portfolios.vanguard.com
• It's a national fund, so it isn't structured to shelter state income tax the way single-state muni ETFs such as NYF are.
• Launched in 2023, it has a shorter live record than muni ETFs that have been trading for over a decade, including its broader sibling VTEB.
