BIL vs USFR: Which Is the Better Pick in 2026?

Overview

BIL and USFR are both Treasury-based fixed-income ETFs that track short-duration government debt, but they target different points on the yield curve. BIL holds Treasury bills with maturities of 1–3 months, offering the shortest possible government exposure with near-zero interest rate sensitivity. USFR invests in Treasury floating-rate notes (FRNs), which reset their coupon rates periodically and typically have longer maturities, giving them modestly higher yield potential but some duration risk.

How they differ

The core difference is maturity and structure: BIL is a pure money-market vehicle holding bills at the shortest end, while USFR holds floating-rate notes with intermediate maturities. Because BIL's holdings reset so frequently, its yield (3.51%) and price move almost lockstep with the Fed funds rate, whereas USFR's floating-rate coupons adjust but the bond itself retains some price risk—evident in USFR's yield of 3.60% being slightly higher. Both charge minimal fees (BIL at 0.14%, USFR at 0.15%), and both distribute monthly. The structural difference shows up in AUM: BIL is substantially larger at $47.8B versus USFR's $17.3B, reflecting the appeal of its near-cash stability for large institutional and retail allocators. USFR's negative beta of –0.02 suggests it may move slightly differently than equity markets during volatile periods, while BIL's beta of 0.06 is essentially flat.

Who each is best for

• BIL: Fits investors who want the shortest possible government debt exposure as a cash substitute or sweep vehicle, with minimal price fluctuation and maximum liquidity in a rising or stable-rate environment.

• USFR: Fits investors seeking a modest yield step-up over bills while staying within the Treasury universe, who can tolerate small intra-month price moves tied to bond-market repricing, and who benefit from rate resets during periods of floating-rate appreciation.

Key risks to know

• Interest rate sensitivity and price decline risk. BIL's price is nearly immune to rate moves because bills mature so quickly; USFR, however, holds notes with longer durations and will experience mark-to-market losses if Treasury yields rise sharply before the next coupon reset. An abrupt 25-basis-point rate increase would leave BIL's NAV essentially flat but could reduce USFR's share price by 0.25–0.50% or more.

• Reinvestment risk in falling-rate scenarios. When the Fed cuts rates, BIL's yield drops almost immediately as short-term bills roll into lower-yielding successors. USFR's floating coupons will decline as well, but the timing and magnitude depend on the reset schedule, creating a period of higher reinvestment uncertainty than static-coupon bonds would face.

• Competitive pressure from direct Treasury purchases. Both funds hold liquid, fungible government debt that investors can buy directly through TreasuryDirect or a brokerage at no fee. The expense ratios are already minimal (0.14–0.15%), but investors focused solely on yield may replicate BIL's returns with slightly lower cost by laddering T-bills themselves.

Bottom line

If you need cash-like stability and immunity to bond-market repricing, BIL's money-market structure and immense liquidity stand out; if you want a modestly higher yield while staying in Treasuries and can accept small price swings tied to rate resets, USFR's floating-rate design offers a middle ground. Past performance does not guarantee future results.
