## Vanguard enters the T-bill ETF race
Vanguard launched VBIL to challenge SGOV, the dominant short-term treasury ETF. The pitch seems obvious: Vanguard usually wins on fees, so VBIL should be the new default.
## Both funds make the same bet
SGOV and VBIL hold nearly identical baskets of short-term Treasury bills maturing in 0-3 months. They're pure yield conduits that reprice every three months and distribute monthly.
## Performance gap is barely visible
Year to date, SGOV returned 2.61% versus VBIL's 2.59%. Over the trailing year, SGOV posted 3.79% against VBIL's 3.76%. The difference is inside daily rounding noise.
## Track record is the real differentiator
SGOV has traded since 2020 and survived the March 2023 banking crisis and debt-ceiling standoffs. VBIL only launched in February 2025 and has never faced a Fed hiking cycle or market stress.
## Liquidity matters more than fees
SGOV's scale produces tighter bid-ask spreads and better liquidity. The yield difference versus VBIL is only one or two basis points, making SGOV the safer default for taxable accounts.

> For a taxable brokerage account holding cash you may touch in the next few months, SGOV remains the safer default.
## When VBIL makes sense
VBIL appeals to investors already in the Vanguard ecosystem who value commission-free trading and the firm's cost structure. It only wins if Vanguard publishes an expense ratio meaningfully below 0.09%.
## Distributions will decline with rate cuts
Both funds distribute state-tax-exempt Treasury interest monthly. As the Fed cuts rates, distributions will fall. SGOV's monthly payout already dropped from $0.36 in September 2025 to $0.31 in September 2026.
## Key takeaway

SGOV remains the safer default for cash parking due to its liquidity, track record through stress events, and negligible yield advantage, while VBIL appeals mainly to existing Vanguard customers.
