SGOV vs VUSB

SGOVAiShares 0-3 Month Treasury Bond ETF

VUSBAVanguard Ultra-Short Bond ETF

In short

SGOV A cash-parking tool that owns nothing but US Treasury bills maturing in three months or less, pays out monthly, and charges 0.09%. Launched in 2020, it has grown into one of the largest bond ETFs around.

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

SGOV The fund seeks to track an index of U.S. Treasury bills with remaining maturities of three months or less.

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

• SGOV 0.09% a year against a 0.14% median for its T-bill peer group, and it is very actively traded, which tends to keep the round-trip cost of getting in and out thin.
• One job, done plainly: track an index of Treasury bills with three months or less to run, and hand out the income monthly. Tracking has been close to the index.ishares.com
• Holdings mature in weeks, so interest-rate sensitivity is minimal and the share price moves very little when yields swing.ishares.com

• 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

• SGOV Cheaper bill funds exist. VBIL lists at 0.06% and CLIP at 0.07%, so the fee advantage here is over the pricier half of the group, not the whole field.
• Income tracks short-term rates. Bills roll every few weeks, so the monthly payout resets quickly in whichever direction rates go.
• The flip side of near-zero duration: no price kicker when rates drop, the way longer-dated Treasury funds get.

• 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
