VGUS vs XHLF

VGUSAVanguard Ultra-Short Treasury ETF

XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

VGUS A one-ticker parking spot at the very front of the Treasury curve: about 90 bills and short notes, passively sampled, income paid monthly. Vanguard opened it in 2025 at 0.07%, under the typical Treasury fund in its peer group.

XHLF Most cash-parking funds pick a maturity bucket. XHLF picks a number: it blends Treasury bills to an average duration of about six months, resets to that target monthly, and charges three basis points to do it.

Stated mandate

VGUS Vanguard says the fund seeks to track a market-weighted Treasury index with an ultra-short dollar-weighted average maturity. It uses passive index sampling and generally invests at least 80% of assets in securities in, or economically similar to, the index.

XHLF The Fund seeks to track the investment results of an index composed of U.S. Treasury securities.

Why people hold it

• VGUS 0.07% a year against a 0.12% median for Treasury funds in its peer group. Fees bite hardest at the short end, where there is no duration cushion to hide them.
• Government paper only: roughly 90 US Treasuries sampled against the Bloomberg Short Treasury Index. No corporate credit, no mortgages, no derivatives overlay.
• Tracking has been tight since launch, and the mandate is plain: at least 80% in index securities or economic equivalents. What it says on the tin is what it holds.
• Pays monthly and slots into Vanguard's Treasury shelf next to VGIT and VTG, so you can move along the maturity ladder without leaving the lineup.

• XHLF Costs 0.03% a year, against a typical short-Treasury peer near 0.14%. In cash-like funds, where returns come from bills everyone owns, fee is the main lever.
• Tracks an index built to hold an average duration of roughly six months, rebalanced monthly, so exposure stays anchored instead of drifting as bills mature.bondbloxxetf.com
• Sits in the gap between 0-3 month bill funds and one-year funds. Its sibling XONE targets a one-year duration at the same 0.03%, so the two can be mixed to dial in duration.
• US Treasury bills only, no credit bets hiding in the portfolio, run in a multi-billion-dollar fund that has stayed close to its index.

Worth knowing

• VGUS Not the cheapest ticker on Vanguard's own bond shelf: VGIT and VTG run 0.03%. The ultra-short slice costs a few extra basis points.
• Ultra-short maturities mean income resets as short-term rates move, up or down. This is a cash-management tool, not a bet on falling yields.
• A 2025 launch, so the history is short and trading is moderate rather than heavy. Worth eyeing the spread on large orders in the first and last minutes of the day.

• XHLF Six months of duration is not zero. Prices move a touch more when yields shift than in 0-3 month bill funds such as BIL or CLIP.
• Income rides whatever Treasury bills happen to pay, and distributions arrive on an irregular rhythm rather than a fixed amount or schedule.
• Volume is moderate next to the largest bill ETFs, so spreads can be a bit wider, which matters more on big tickets than small ones.
