Overview
BND and SGOV are both Treasury-backed bond ETFs tracking fixed-income indexes, but they serve nearly opposite roles in a portfolio. BND holds the full U.S. bond market—Treasuries, investment-grade corporates, mortgage-backed securities, and asset-backed securities—tracking the Bloomberg U.S. Aggregate Float Adjusted Index. SGOV holds only Treasury bills maturing within three months, tracking the ICE 0-3 Month US Treasury Securities Index. The gap between them is duration: BND carries meaningful interest-rate sensitivity; SGOV is a cash-like instrument.
How they differ
BND's most significant difference is its broad diversification across the entire investment-grade bond market, giving it 4.17% yield but also duration risk (beta of 0.98), meaning its price moves with rates. SGOV is duration-free—its negative beta of -0.0029 reflects near-zero rate sensitivity—because it holds only ultra-short Treasury paper. That safety costs yield: SGOV delivers 3.66%, a 51-basis-point haircut versus BND. Both charge minimal expenses (0.03% for BND, 0.07% for SGOV), but SGOV commands a much smaller asset base at $103B versus BND's $162B, and its distributions are fully backed by Treasury interest, while BND's mix includes credit risk from corporate and agency exposures.
Who each is best for
BND: Fits investors seeking meaningful current income from investment-grade bonds while accepting mild interest-rate risk and credit exposure across the U.S. bond market. Works for those building a core fixed-income allocation or supplementing equity portfolios.
SGOV: Fits investors prioritizing capital preservation and liquidity over yield—those using short-term Treasury bills as a cash substitute or a ballast against equity volatility. Designed for conservative allocations or intermediate parking of capital awaiting deployment elsewhere.
Key risks to know
- Duration and rate risk (BND): BND's 0.98 beta means a 1% rise in longer-term interest rates will erode NAV by roughly 1%, since the fund holds bonds with average maturities well beyond the 3-month horizon. SGOV's near-zero beta shields it from this entirely.
- Credit and concentration risk (BND): BND's exposure to corporate bonds, mortgage-backed securities, and agency debt introduces credit-spread risk. Widening corporate or real-estate credit spreads during recessions can pressure NAV independently of Treasury rates.
- Reinvestment-yield risk (SGOV): SGOV's 3.66% yield assumes rollover of maturing bills into similar-rate securities. A sharp decline in Treasury yields would reduce forward distributions substantially.
- AUM and liquidity: SGOV's $103B is far smaller than BND's $162B, which may affect trading tightness in volatile markets, though both remain highly liquid.
Bottom line
If you value a diversified income stream and can tolerate interest-rate headwinds, BND's broader market exposure and higher yield make sense. If you need a rate-insensitive cash alternative that still beats money-market fund returns, SGOV delivers that simplicity. Past performance does not predict future results.
