TLDR vs XHLF

TLDRBThe Laddered T-Bill ETF

XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

TLDR Most T-bill ETFs just track a 0-3 month index. TLDR runs an actively managed ladder of bills maturing inside six months, targeting a 60-day average maturity, with a manager choosing where on the front end to sit.

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

TLDR The Fund seeks current income while preserving capital and maintaining daily liquidity.

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

Why people hold it

• TLDR An active ladder, not an index sleeve: REX rolls the bill positions continuously around a targeted 60-day average maturity, tuned to the front end of the Treasury curve.rexshares.com
• Under normal conditions at least 80% of net assets sit in US Treasury bills maturing in six months or less, the shortest end of government paper.sec.gov
• Distributions land monthly, and the mandate stays plain: current income, capital preservation, daily liquidity.

• 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

• TLDR The 0.20% fee sits above the index bill funds next to it (XONE 0.03%, VBIL 0.06%, BIL 0.14%). The active laddering is what the extra buys.
• A small, thinly traded fund so far, so spreads can run wider than the category's giants.
• Launched in 2026, so there is little history behind the manager's ladder calls, and the prospectus flags high portfolio turnover as a cost and tax factor.rexshares.com

• 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.
