Overview
BND and SGOV are both fixed-income ETFs tracking broad U.S. Treasury or bond indexes, but they target opposite ends of the maturity spectrum. BND holds the entire U.S. investment-grade bond market—Treasuries, mortgages, corporates, and agencies—with durations spanning decades. SGOV holds only ultra-short Treasury bills maturing in zero to three months, functioning as a near-cash instrument with minimal interest-rate risk.
How they differ
The fundamental split is maturity: BND carries a beta of 0.98, meaning its price moves in lockstep with broad bond-market shifts, while SGOV's beta of -0.0029 indicates it's effectively immune to rate swings—it rolls over bills constantly and holds almost no duration risk. BND yields 4.03% and SGOV yields 3.53%, a difference that reflects the maturity premium; longer bonds compensate for interest-rate exposure that short bills don't have. BND is vastly larger at $158B in AUM versus SGOV's $95.2B, and both charge minimal fees (0.03% and 0.07% respectively), so cost plays almost no role in the decision.
Who each is best for
BND: Fits investors seeking a diversified, passive core fixed-income holding with meaningful yield and price appreciation potential when rates fall, and who can tolerate multi-year swings tied to duration changes.
SGOV: Fits investors who need liquidity, stability of principal, and a current-income stream that floats with the Fed funds rate—those treating their bond allocation as a substitute for a money market fund rather than a longer-term credit investment.
Key risks to know
- Duration and interest-rate risk (BND): A 1% rise in rates would typically produce a 5–7% decline in NAV, given the fund's market-level duration. SGOV has virtually no duration risk and will hold par value.
- Credit and spread risk (BND): The fund holds corporate bonds and mortgages alongside Treasuries. In a credit downturn or widening-spread environment, these assets can underperform the Treasury sleeve; SGOV avoids this entirely by holding only bills.
- Reinvestment-rate compression (SGOV): As bills mature and roll, yields track the current Fed funds rate. If rates fall sharply, new rolls will reset at lower coupons; this is a mechanical feature of the strategy, not a failure, but contrasts with BND's locked-in longer coupons.
- Limited upside (SGOV): Because SGOV holds only near-zero-coupon bills, it cannot capture the price appreciation that BND can achieve if rates decline significantly.
Bottom line
If you're building a core bond allocation and want current income plus the possibility of capital gains when rates decline, BND's broad diversification and duration exposure align with that goal. If you need a stable, liquid holding that mirrors short-term interest rates and don't want principal volatility, SGOV functions as a Treasury-backed alternative to money market funds. Neither is inherently "better"—the choice hinges on whether you view your bond sleeve as a long-term investment or a near-cash parking spot.
