ULST vs XHLF

ULSTBState Street Ultra Short Term Bond ETF

XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

ULST The active option in a category full of index trackers: State Street's managers hand-pick roughly 300 short, high-quality bonds to squeeze income out of cash-adjacent money, and pay it out monthly.

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

ULST ULST seeks to maximize current income while preserving capital and maintaining daily liquidity through short-duration, high-quality investments. It is actively managed and invests in securities somewhat longer-term than traditional cash vehicles.

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

Why people hold it

• ULST Actively managed, not index-bound. The Bloomberg US Treasury Bellwether 3 Month Index is the yardstick, not the leash, so managers can shift across roughly 300 short, high-quality holdings.ssga.com
• Launched in 2013, it has run through a full rate cycle, from zero-bound years to the hiking era, with the same short-duration mandate.
• Income lands monthly, which suits the job it is built for: parking money that needs to stay liquid and still earn something.ssga.com
• It stays in its lane. The portfolio has hewed closely to the short-duration, high-quality brief in its own documents rather than drifting into longer or riskier paper.

• 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

• ULST At 0.20%, the fee sits right at the category median while several large rivals run cheaper (VUSB at 0.10%, SHV at 0.15%). Active management is what the gap buys.
• Not a money market fund. It holds paper somewhat longer than traditional cash vehicles, so the share price floats instead of pinning to a dollar.ssga.com
• Volume is moderate rather than category-leading, so bid-ask spreads carry more weight here than at the biggest ultra-short 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.
