DUSB vs XHLF

DUSBADimensional Ultrashort Fixed Income ETF

XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

DUSB Most of this category just buys T-bills. Dimensional's ultrashort fund is the active one: corporates, bank paper and foreign dollar bonds, 0.14% net of a waiver through February 28, 2027.

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

DUSB The fund seeks to maximize total returns, consisting of income and capital appreciation. It generally invests in investment-grade fixed-income securities, usually maturing within one year, while maintaining a weighted average maturity of no more than one year.

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

Why people hold it

• DUSB The prospectus lets it lean into longer-dated paper when the term premium looks bigger, and stay short when it doesn't, with weighted average maturity capped at one year.sec.gov
• Wider menu than a bill fund: Treasuries, agencies, corporates, commercial paper, bank obligations and dollar bonds of foreign issuers. Roughly 400 positions, paid out monthly.sec.gov
• Fee sits near the category median at 0.14%, net of a waiver through February 28, 2027 (0.15% gross), and it is one of the stronger mandate implementations in the group.

• 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

• DUSB Credit risk is the trade-off. Corporate and bank paper can widen in a stress episode in ways pure T-bill funds like VBIL and CLIP don't.sec.gov
• Costs more than the index bill crowd: 0.14% net of a waiver through February 28, 2027 against 0.06% for VBIL and 0.07% for CLIP. The active work has to earn that gap.
• Moderately traded and a 2023 launch, so it is younger and less busy than the category's biggest names.

• 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.
