Overview
SGOV and SHY are both Treasury ETFs from iShares that pay monthly distributions, but they target sharply different points on the maturity spectrum. SGOV holds Treasury bills maturing in three months or less, while SHY holds Treasury notes with 1–3 years to maturity. That difference drives everything else: duration risk, interest-rate sensitivity, and yield potential.
How they differ
The single biggest difference is maturity: SGOV's ultra-short duration (effectively cash-like, with a beta of −0.0029) versus SHY's 1–3 year duration (beta of 0.22). This means SHY will fluctuate more when interest rates move, while SGOV's price stays nearly flat. Despite similar distribution rates (SGOV 3.66%, SHY 3.67%), SHY's longer bonds carry more duration risk and offer more price-appreciation potential if rates fall. SGOV costs 0.07% annually to hold versus SHY's 0.15%, but SHY's $25.2B in AUM is well-established (inception 2002), while SGOV is newer (2020) but significantly larger at $99.9B.
Who each is best for
SGOV: Fits investors seeking a cash-equivalent holding that generates a yield above money-market accounts, with zero interest-rate risk and minimal price volatility. Works for very short time horizons or as a placeholder for capital awaiting deployment.
SHY: Fits investors comfortable with modest duration risk in exchange for slightly higher yield potential and the possibility of price appreciation if rates decline. Designed for intermediate-term Treasury exposure with monthly income.
Key risks to know
- Duration and rate risk: SHY's 1–3 year maturity profile means its price will move inversely with interest rates—if rates rise, the fund's NAV falls, locking in losses for sellers. SGOV is largely insulated from this risk.
- Reinvestment risk at rates compression: Both funds face reinvestment pressure if rates fall. SGOV's shorter maturities force more frequent rollover into lower-yielding instruments; SHY has longer to cushion rate declines but still rolls over regularly.
- Opportunity cost in a rising-rate environment: If the Fed keeps rates elevated, both funds lock in current yields, but SHY's longer duration makes it a more visible drag versus holding cash or higher-yielding alternatives if rates stay steady.
Bottom line
If you want Treasury exposure with zero interest-rate risk and the lowest possible fees, SGOV's ultra-short duration and 0.07% expense ratio make it a natural fit. If you're willing to accept modest price volatility in exchange for a slightly longer yield cushion and potential capital appreciation when rates fall, SHY's track record and 1–3 year positioning offer more flexibility.
