Overview
BIL and JPST are both ultra-short fixed-income ETFs designed for investors seeking monthly income with minimal principal volatility, but they take different approaches to achieving it. BIL holds only Treasury bills maturing in 1–3 months, while JPST invests in a diversified basket of short-term, investment-grade corporate and government debt. The key trade-off is between pure safety and simplicity (BIL) versus a modest yield premium (JPST) in exchange for broader credit exposure.
How they differ
BIL's strategy is Treasury-only exposure through the Bloomberg 1-3 Month U.S. Treasury Bill Index, meaning it carries zero credit risk and tracks the safest corner of the debt market. JPST, by contrast, builds a diversified portfolio of investment-grade fixed and floating-rate debt—including corporates, agencies, and other short-term instruments—to boost yield.
That yield difference shows up clearly: JPST distributes 4.04% versus BIL's 3.58%, a 46-basis-point spread that compounds over time. Both charge minimal expenses (BIL at 0.14%, JPST at 0.18%), so the yield gap reflects genuine underlying returns, not fee arbitrage.
Both are substantial funds with similar size and beta: BIL holds $47.1B in assets with a beta of 0.06, while JPST has $40.4B and matches that 0.06 beta. JPST is newer, having launched in 2017 versus BIL's 2007 inception, meaning BIL has longer track record through various rate cycles.
Who each is best for
BIL: Fits investors who prioritize capital preservation and credit-risk elimination above yield, and view the portfolio as a cash substitute or ultra-safe anchor for a larger allocation.
JPST: Designed for investors comfortable accepting minimal credit risk from investment-grade issuers in exchange for a modest current-income boost and broader diversification than Treasury bills alone.
Key risks to know
- Credit risk in JPST. While investment-grade debt is safer than high-yield, it still carries default and downgrade risk that Treasury bills do not. A widening of credit spreads or an economic contraction could pressure JPST's NAV or distribution capacity, whereas BIL's Treasury holdings are backed by the U.S. government.
- Interest rate sensitivity. Both funds hold short-duration debt, but JPST's diversified portfolio may experience slightly larger NAV swings if rate expectations shift sharply, since corporates and agencies can reprice faster than Treasury bills.
- Yield compression in a low-rate environment. If short-term Treasury yields fall significantly, BIL's yield could collapse below 2%, narrowing JPST's premium. Conversely, if rates spike, both distributions could rise, but JPST's credit exposure might also widen spreads.
- Floating-rate note repricing risk. JPST includes floating-rate debt, meaning its yield will reset upward or downward as benchmark rates change, creating reinvestment timing risk that BIL's static T-bill ladder does not face.
Bottom line
If you want zero credit risk and maximum simplicity, BIL offers pure Treasury exposure with a 17-year track record; if you're willing to accept investment-grade credit exposure for a 46-basis-point yield boost and broader diversification, JPST delivers similar low volatility at a higher income level. Both are suitable for cash positioning or short-duration allocations, though they are not risk-free—spread widening and rate swings can affect NAV. Past performance does not predict future results.
