SGOV vs SHY: Which Is the Better Pick in 2026?

Overview

SGOV and SHY are both iShares Treasury ETFs that track different segments of the U.S. Treasury yield curve. SGOV holds bills maturing in 0–3 months and yields 3.57%, while SHY extends that window to 1–3 year bonds at 3.55%. The core difference is maturity risk: SGOV sits near cash with minimal interest-rate sensitivity, whereas SHY carries modest duration exposure that rises and falls with longer-term Treasury moves.

How they differ

SGOV's 0–3 month maturity window makes it functionally a cash-equivalent holding—its beta of -0.0029 confirms near-zero price sensitivity to equity or rate swings. SHY, by contrast, has a beta of 0.23, meaning its price moves modestly when Treasury yields shift; a 1% rate rise will dent its NAV slightly more than SGOV's. On yield, both offer similar distribution rates (3.57% vs. 3.55%), so the real draw isn't extra income—it's the duration tradeoff. SGOV's expense ratio of 0.07% undercuts SHY's 0.15%, though the larger difference is AUM: SGOV's $95.2B dwarfs SHY's $25.3B, reflecting its appeal as a Treasury cash substitute. SHY has the longer track record (inception July 2002 vs. May 2020) but less institutional asset backing.

Who each is best for

SGOV: Fits investors treating Treasury exposure as a liquid holding place for cash reserves, especially those indifferent to capturing longer-dated Treasury yields and unwilling to accept even modest rate-induced price swings.

SHY: Designed for investors seeking a slightly higher yield than money-market funds or SGOV while accepting modest duration risk—useful for laddered bond portfolios or as a core short-duration holding in a fixed-income sleeve.

Key risks to know

• Duration and rising-rate risk (SHY): A meaningful increase in 1–3 year Treasury yields will erode SHY's NAV; SGOV's near-zero beta means this risk barely applies to it. Investors holding SHY through a period of rising rates will see temporary principal losses.

• Reinvestment-rate pressure on SGOV: Because SGOV rolls bills every few weeks, falling short-term rates will compress its yield faster than SHY's. If the Fed cuts, SGOV holders may see distribution rates drop sharply within months.

• Liquidity and spread risk (SHY): Though liquid, SHY's smaller AUM means wider bid-ask spreads in fast markets; SGOV's $95.2B asset base gives it tighter execution costs.

• Credit risk (minimal but present): Both hold only Treasury securities backed by the U.S. government, but SGOV's shorter maturity means less embedded credit-risk premium; SHY's 1–3 year bonds carry a hair more yield pickup for that reason.

Bottom line

If you need a parking place for cash that earns a government-backed yield with zero interest-rate risk, SGOV's scale and near-zero beta make it the natural default. If you're willing to tolerate modest NAV swings in exchange for a bit of extra yield and slightly longer maturity, SHY fits investors building a dedicated short-duration bond position. Both carry minimal credit risk; the choice hinges on how much rate sensitivity you'll tolerate and whether you prioritize ultra-low fees and liquidity over a fractionally longer maturit curve.
