SGOV vs VBIL
iShares’ SGOV and Vanguard’s VBIL are near-twins: both own Treasury bills maturing within three months and pay monthly. The differences are fees, size and trading liquidity.
By the SGOVResource.com editorial team Last reviewed Data refreshed How we calculate Editorial policy
Short answer: SGOV and VBIL are close substitutes. VBIL’s listed expense ratio (0.07%) is 2 basis points lower than SGOV’s (0.09%), worth about $20.00 a year on $100,000. SGOV has a much longer track record (since 2020) and far more assets and trading volume. For most investors the choice comes down to which fund their broker trades commission-free and whether the small fee gap matters.

Key differences
Fees
Both are among the cheapest Treasury bill funds. The gap is a few hundredths of a percent, which matters most for large balances held for years. Because both funds report a 30-day SEC yield net of expenses, comparing SEC yields captures the fee difference automatically.
Index and holdings
SGOV tracks the ICE 0-3 Month US Treasury Securities Index (USD); VBIL tracks the Bloomberg US Treasury Bills 0-3 Months Index. Both indexes hold the same type of security with the same maturity window, so day-to-day behavior should be very similar. Small yield differences come from which specific bills each fund holds.
Size and liquidity
SGOV is one of the largest ETFs in the US, with $116,778,844,862 in net assets and roughly 23 million shares traded per day on average. VBIL launched in 2025 and is smaller. Both are easy to trade for ordinary order sizes; very large orders may get tighter spreads in SGOV.
Taxes
Income from both is generally taxed as ordinary income federally and is largely exempt from state income tax because it comes from Treasury bills. Each issuer publishes its own annual US government income percentage.
Which might suit you
- SGOV if you value the longest track record and deepest trading liquidity in the category, or already hold it and don’t want to realize a gain or loss.
- VBIL if you are minimizing fees on a large balance, or prefer to consolidate holdings at Vanguard.
