Overview
SGOV and SHV are both Treasury bond ETFs from iShares that invest exclusively in short-term U.S. government securities, but they differ in maturity range and fund age. SGOV tracks bills maturing in three months or less, while SHV holds Treasuries with one to twelve months remaining. Both offer monthly distributions and expense ratios well under 0.20%, making them functionally equivalent as cash-like positions for conservative investors.
How they differ
The biggest distinction is maturity: SGOV's ultra-short three-month maximum horizon makes it closer to cash, while SHV's twelve-month ceiling gives it slightly more duration risk and yield potential. SGOV charges 0.07% annually versus SHV's 0.15%—a small gap, but one that compounds over time on lower yields. Distribution rates are nearly identical (SGOV at 3.67% and SHV at 3.70%), so the fee difference is the meaningful structural advantage for SGOV. SGOV is far larger at $99.9B in assets compared to SHV's $20.6B, which typically translates to tighter spreads and easier entry and exit.
Who each is best for
SGOV: Fits investors who want maximum stability and minimal interest-rate sensitivity, with a preference for the lowest possible fees on Treasury holdings. Useful as a core cash reserve or for accounts where basis points matter over a multi-decade holding period.
SHV: Designed for investors comfortable with modest additional duration (up to one year) in exchange for marginally higher yield, or those who inherited a position in an established fund and see no compelling reason to switch.
Key risks to know
- Rising-rate pressure on both: Although duration is minimal, SHV's longer maturity window means its NAV will decline more if Treasury yields spike, while SGOV's three-month maximum provides near-complete insulation from rate moves.
- Reinvestment-rate cliff: When held bills and notes mature, both funds reinvest proceeds at prevailing rates. If yields fall sharply, monthly distributions could compress meaningfully on the next roll-over cycle.
- Minimal credit risk, but negligible total return potential: Both hold only U.S. Treasury securities backed by the full faith of the federal government. The tradeoff is that current yields of ~3.7% are the realistic ceiling for returns; no price appreciation is likely.
- Fee drag over long horizons: The 0.08 percentage-point gap between SGOV and SHV seems trivial but amounts to roughly 2–3% of annual yield lost to SGOV's competitor over decades of compounding.
Bottom line
If you value simplicity and cost efficiency with zero interest-rate sensitivity, SGOV's three-month maturity and lower fee stand out. If you're already in SHV and comfortable with its slightly longer duration for a nearly identical yield, the switching cost and tax friction probably don't justify a move. Past performance doesn't predict future results; both funds' returns will depend entirely on where Treasury yields head next.
