BKUI vs XHLF

BKUIABNY Mellon Ultra Short Income ETF

XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

BKUI BNY's take on the parked-cash corner: an investment-grade ultra-short bond fund at 0.13% a year, spread across roughly 160 positions, paying income 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

BKUI The fund seeks high current income while maintaining liquidity and limiting principal volatility. It normally invests at least 80% of net assets in investment-grade, U.S.-dollar fixed, variable or floating-rate debt or cash equivalents.

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

Why people hold it

• BKUI 0.13% a year undercuts the ultra-short category's typical fee, and lands below top-rated peers like SHV, PULS and DUSB at 0.15%.
• The mandate is plain-spoken: at least 80% of net assets in investment-grade dollar debt (fixed, variable or floating rate) or cash equivalents.
• Income arrives monthly, and the book spreads across roughly 160 positions rather than a handful of bills.
• Sits in the upper tier of a crowded ultra-short field of nearly 30 funds on our review.

• 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

• BKUI The goal is limited principal volatility, not zero. This is short-dated credit, not a deposit account, so the share price can move.
• With floating and variable-rate paper in the mix, the monthly payout floats with short-term rates instead of holding a set coupon.
• Trading is moderate rather than the deepest in the category, which matters most on large orders.

• 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.
