SGOV vs VBIL

SGOVAiShares 0-3 Month Treasury Bond ETF

VBILAVanguard 0-3 Month Treasury Bill 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.

VBIL Vanguard's cash-parking ETF: roughly two dozen Treasury bills, none maturing more than three months out, at 0.06% a year. It landed in 2025 and undercut most of the T-bill shelf on price.

Stated mandate

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

VBIL VBIL seeks to track the performance of a market-weighted Treasury index with an ultra-short-term dollar-weighted average maturity, using a passive approach designed to follow the Bloomberg U.S. Treasury Bills 0-3 Months Index.

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

• VBIL It charges 0.06% a year, well under the 0.14% median for 0-1 year Treasury funds and under the category veteran, BIL.
• Plain passive mandate on the Bloomberg U.S. Treasury Bills 0-3 Months Index, tracked very closely. One of the tightest implementations in its peer group.vanguard.com
• Roughly two dozen bills backed by the US Treasury, every one maturing inside three months. Interest goes out monthly.
• A multi-billion-dollar fund with active daily trading, which tends to keep bid-ask costs small.

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.

• VBIL The payout floats with short-term rates. Monthly income rises and falls with what bills yield, and nothing about it is fixed.
• It opened in 2025, so its live record is short next to T-bill funds that have been running for years.
• Stretching maturity gets cheaper: peer XONE targets one-year duration at 0.03%, trading lower cost for more rate sensitivity.
