CATF vs VTEB

CATFBAmerican Century California Municipal Bond ETF

VTEBAVanguard Tax-Exempt Bond ETF

In short

CATF A California-only muni portfolio that is actively run, not index-tracked: roughly 400 investment-grade bonds picked for income exempt from federal and California income taxes, at 0.25% with no fee waiver involved.

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

CATF The fund seeks high current income exempt from federal and California income taxes. It primarily invests in investment-grade bonds exempt from those taxes, using top-down credit and duration analysis plus research-driven security selection.

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

• CATF Income aims to dodge two tax bills, not one: the portfolio sits in investment-grade bonds exempt from both federal and California income taxes, and it pays out monthly.americancentury.com
• Human judgment, not a rulebook: top-down credit and duration calls plus bond-by-bond research including nonrated names, with the S&P California AMT-Free index as the yardstick.americancentury.com
• 0.25% with no fee waiver sits near the muni category median and close to index-tracker TFI at 0.23%, a tight price for active, single-state management.
• Sits in the upper half of a crowded muni ETF field, and what it holds matches what it promises: California paper, investment grade, income first.

• 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

• CATF Thinly traded and still a modest-sized fund, so bid-ask spreads can run wider than the category's national giants and larger orders need more care.
• One state, one budget. All-California issuers means the portfolio rides California's economy, and the state exemption only counts if you pay California income tax.
• Launched in 2024, so the track record is short next to muni funds with decades of rate cycles behind them.

• 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
