Overview
BIL and USFR are both ultra-short Treasury funds, but they serve different roles in a fixed-income portfolio. BIL holds Treasury bills with maturities between one and three months, while USFR holds floating-rate Treasury notes that reset periodically based on short-term rates. Both carry virtually no credit risk and offer similar yields around 3.5β3.6%, but their interest-rate sensitivity and duration characteristics differ meaningfully.
How they differ
The core distinction is maturity and rate sensitivity. BIL invests in bills maturing in one to three months, giving it near-zero duration and near-zero price volatility (52-week range: $91.26β$91.78). USFR holds longer-dated floating-rate notes, which reset their coupons as rates change, providing slightly more yield cushion if rates fall but also carrying modest duration risk (52-week range: $50.23β$50.49). Both charge low expense ratiosβBIL at 0.14% and USFR at 0.15%βbut BIL has substantially larger assets under management at $50 billion versus USFR's $17.6 billion. The yield difference is negligible: BIL's 3.53% distribution rate versus USFR's 3.61%. BIL's monthly distributions are sized at $0.26 per share versus USFR's $0.15, reflecting different share prices and underlying valuations rather than fundamentally different income streams.
Who each is best for
- BIL: Conservative investors seeking maximum stability and liquidity, including those building a cash-equivalent core holding or deploying funds into volatile markets. Ideal for short-term reservoirs and risk-averse bond allocations.
- USFR: Investors with a one- to three-year time horizon who want slightly higher yield than money-market funds without committing to traditional fixed-rate bonds. Works well for those who expect rates to remain stable or decline modestly.
Key risks to know
- Interest rate risk: BIL is virtually immune to rate moves due to short maturity. USFR has floating-rate coupons, but longer duration still exposes it to modest price decline if rates spike unexpectedly.
- Reinvestment risk: BIL's one-to-three-month bills roll frequently, meaning investors face reinvestment at lower yields if rates drop. USFR's floating-rate structure mitigates this.
- Liquidity and scale: BIL's $50 billion AUM ensures deep secondary-market liquidity. USFR's $17.6 billion is substantial but notably smaller, potentially widening bid-ask spreads during stressed markets.
- Basis risk: Both track indices closely, but USFR's floating-rate note index is less widely held and may experience periodic tracking differences versus BIL's Treasury-bill benchmark.
Bottom line
If you need a true cash substitute with zero volatility and instant liquidity, BIL is the cleaner choice. If you can tolerate modest price fluctuation and have a slightly longer holding period, USFR's floating-rate structure offers comparable yield with a hedge against falling rates. Neither fund is suitable as a long-term growth holdingβthey're tools for parking capital safely in a low-rate environment. Past performance doesn't predict future returns; both depend on the path of short-term Treasury yields and monetary policy.
