Overview
BIL and USFR are both Treasury-focused fixed-income ETFs with minimal credit risk, but they track different maturity and rate-sensitivity profiles. BIL holds Treasury bills maturing in 1–3 months, functioning as a money-market proxy with near-zero interest-rate sensitivity. USFR invests in floating-rate Treasury notes, which reset their coupons periodically in line with short-term Treasury rates, offering modest duration exposure and upside if short rates rise.
How they differ
The single biggest difference is maturity and rate structure: BIL holds short-term, fixed-rate bills that mature within three months, while USFR holds intermediate floating-rate notes that reset their rates to current Treasury benchmarks. This makes USFR sensitive to changes in short-term rates in a way BIL is not—if rates spike, USFR's coupons increase, but if rates fall, they decline.
Second, the yield spread is modest but real: USFR's 3.80% distribution rate edges BIL's 3.58%, a 22-basis-point difference that reflects USFR's slightly longer average maturity and reset mechanics.
Third, AUM and fund age diverge materially. BIL is far larger ($46.7B versus $18.6B) and older (since 2007), giving it deeper liquidity and longer track record. Expense ratios are nearly identical (0.14% vs. 0.15%), so fund size is the tiebreaker on cost efficiency.
Who each is best for
BIL: Fits investors seeking ultra-stable principal and income with no interest-rate risk, who treat Treasury bills as cash equivalents and prioritize immediate liquidity and predictability over yield.
USFR: Designed for investors comfortable with modest intermediate-term duration who want a Treasury yield pickup and believe short rates will hold steady or rise, making the floating-rate reset feature attractive relative to fixed-rate alternatives.
Key risks to know
- Duration and rate-rise sensitivity for USFR. While shorter than a traditional bond fund, USFR has positive duration; if short-term Treasury rates fall sharply, note prices decline and distributions shrink. BIL's near-zero duration shields it from this risk.
- Floating-rate coupon reset lag. USFR's coupon resets on a schedule (typically quarterly); if rates move between reset dates, the fund's yield won't adjust immediately, creating timing mismatches in a rapidly shifting rate environment.
- Opportunity cost in a falling-rate scenario. If the Fed cuts rates substantially, USFR's income will decline alongside its reset coupons, whereas BIL investors can reinvest maturing bills at whatever new lower rates prevail. Over a sustained easing cycle, USFR's total return may lag.
- Limited yield cushion. Both funds distribute yields in the 3.5–3.8% range; at current Treasury levels, there is little room for yields to rise without the funds' NAVs compressing, particularly for USFR if rates rise faster than floaters can reprice.
Bottom line
If you prioritize absolute stability and liquidity and treat this as a cash substitute, BIL's money-market characteristics and larger scale stand out. If you're willing to accept modest interest-rate risk in exchange for a slightly higher coupon and bet that rates will remain elevated or rise, USFR offers a modest yield pickup with floating-rate upside. Both offer Treasury-backed safety; the choice hinges on whether you want zero duration or modest positive duration in the current rate environment. Past performance does not predict future results.
