SCUS vs VUSB

SCUSBSchwab Ultra-Short Income ETF

VUSBAVanguard Ultra-Short Bond ETF

In short

SCUS Schwab's cash-parking entry: an actively managed sleeve of short-dated investment-grade dollar debt, measured against 3-month T-bills, at 0.14% a year. That undercuts the typical ultra-short bond ETF, and most active ones too.

VUSB Vanguard's first actively managed bond ETF, run by its in-house fixed income team and priced at 0.10%. It holds investment-grade paper maturing inside two years: a step past a money fund, well short of a real bond fund.

Stated mandate

SCUS The fund seeks current income consistent with capital preservation while maintaining liquidity. It actively invests in investment-grade, short-term, U.S.-dollar-denominated debt securities issued by U.S. and foreign issuers.

VUSB The fund seeks current income with limited price volatility while investing in diversified high- and medium-quality fixed-income securities. It expects to maintain a dollar-weighted average maturity of 0–2 years.

Why people hold it

• SCUS 0.14% a year undercuts the ultra-short category's 0.20% median, and lands below active rivals like PULS at 0.15%.
• Active, not index-tracking: managers pick among short-dated investment-grade dollar bonds from US and foreign issuers, with capital preservation and liquidity written into the mandate.
• Income arrives monthly, drawn from roughly 150 positions rather than a handful of bills.
• Sits in the upper half of a crowded ultra-short bond field, with cost doing the heavy lifting.

• VUSB At 0.10%, it costs half the typical ultra-short bond ETF and undercuts the other leaders in the group: SHV, PULS, FLDR and DUSB all charge 0.15%.
• Active, not adventurous. The managers buy investment-grade bonds (A3-or-better high quality plus BBB-tier medium quality) and hold average maturity to zero-to-two years.vanguard.com
• Income lands monthly, sourced from roughly 170 bonds, so no single issuer drives the outcome.
• A multi-billion-dollar fund that trades actively, and the same portfolio team also runs a similar Vanguard ultra-short fund.vanguard.com

Worth knowing

• SCUS Launched in August 2024, so the track record is short next to ultra-short mainstays like SHV.
• Assets are modest and trading is moderate, so spreads can run wider than at the category's biggest names.
• Benchmarked to 3-month T-bills, but it buys credit rather than only government paper, so the share price can move when spreads widen.

• VUSB This is not a money market fund. No fixed $1 share price, and the market price can trade above or below the value of the holdings.vanguard.com
• The mandate allows BBB-tier credit, a notch of risk a Treasury-only neighbor like SHV doesn't take.vanguard.com
• Bonds this short reprice with short-term rates, so the monthly payout drifts up and down instead of holding a set level.vanguard.com
