Vanguard Total Bond Market ETF (BND) includes a significant portion of corporate bonds, which are correlated with stocks and lose value when equities fall, reducing its effectiveness as a shock absorber in portfolios. In 2026, rising inflation and steady interest rates make this flaw more apparent, as BND's yield barely outpaces inflation and credit spreads offer little compensation. The iShares U.S. Treasury Bond ETF (GOVT), holding only Treasuries, provides a cleaner bond exposure that better cushions against market downturns despite offering slightly lower yields. Investors should reconsider BND's small yield advantage versus its reduced diversification benefit amid current economic conditions.
