SGOV vs. VBIL: Vanguard Finally Has a T-Bill ETF, So Is It the Cheaper Place to Park Cash?
Vanguard finally built a T-bill ETF to challenge the category king, and the fee story is not as simple as Vanguard fans expect. The real tiebreaker has nothing to do with basis points.
For years, investors parking cash in an ETF had one obvious default: iShares 0-3 Month Treasury Bond ETF (NYSEARCA:SGOV). Now Vanguard has entered the ring with Vanguard 0-3 Month Treasury Bill ETF (NASDAQ:VBIL), and the pitch writes itself: Vanguard usually wins on fees, so VBIL should be the new default. The reality is closer than the marketing suggests, and the tiebreaker lies elsewhere.
What Each Fund Is Actually Betting On
Both funds make the same bet: that the shortest slice of the Treasury curve is the safest, most rate-sensitive place to hold dollars. SGOV tracks the ICE 0-3 Month US Treasury Securities Index. VBIL holds a nearly identical basket of bills, with its June 30, 2026 NPORT filing showing roughly two dozen individual bill CUSIPs and a tiny 0.04% sleeve in the Vanguard Market Liquidity Fund.
Both funds are pure yield conduits. As the Fed funds upper bound moved to 4.00% on September 17, 2026, both portfolios reprice inside three months. That is the entire thesis: own the front end, collect what the Treasury pays, and hand it back monthly. The current reference rate is a 4.08% yield average on the 13-week bill, and both funds live essentially on top of that number minus fees.
Where the Difference Shows Up (Barely)
Year to date, SGOV has returned 2.61% versus VBIL at 2.59%. Over the trailing year, SGOV posted 3.79% against VBIL’s 3.76%. That gap is inside the noise of daily NAV rounding.
The distribution comparison looks larger than it is because the funds trade at different share prices. SGOV closed near $100.59 and paid $3.71 per share over the trailing 12 months. VBIL trades near $75.63 and paid $2.67. Adjust for price and the yields land in the same zip code.
Track record is where SGOV genuinely differentiates. It has traded since 2020. VBIL’s price history only begins February 11, 2025, meaning it has never operated through a Fed hiking cycle, a debt-ceiling standoff, or the March 2023 banking scare that stress-tested short-Treasury liquidity.
Practical Comparison
| Metric | SGOV | VBIL |
|---|---|---|
| Issuer | iShares | Vanguard |
| Expense ratio | 0.09% | Not disclosed in latest filing |
| YTD return | 2.61% | 2.59% |
| 1-year return | 3.79% | 3.76% |
| Distribution frequency | Monthly | Monthly |
| Net assets | Largest in category | $9.35 billion |
| Trading history | Since 2020 | Since early 2025 |
Both distribute state-tax-exempt Treasury interest monthly, both hold nothing but bills, and both will see distributions decline if the Fed continues cutting after its September 17, 2026 move. SGOV’s monthly payout has already drifted from $0.36 in September 2025 to $0.31 in September 2026 as short rates fell.
Verdict
For a taxable brokerage account holding cash you may touch in the next few months, SGOV remains the safer default. Its scale produces tighter bid-ask spreads, its history spans real stress events, and the yield differential versus VBIL is inside a basis point or two. VBIL makes sense for an investor already inside the Vanguard ecosystem who values commission-free trading and the firm’s mutualized cost structure, and who is comfortable owning a fund whose operational track record is still short. The calculus flips if Vanguard formally publishes an expense ratio meaningfully below 0.09%. Until then, the incumbent still wins on the two things that matter for a cash sleeve: liquidity and a proven ability to handle a bad week.
