Overview
BND and LQD are both investment-grade bond ETFs that pay monthly distributions, but they track different indexes with meaningfully different compositions. BND holds the full U.S. bond market—Treasuries, agencies, mortgage-backed securities, and corporates—while LQD focuses exclusively on investment-grade corporate bonds. That structural difference drives their yield, duration, and credit-risk profiles.
How they differ
The biggest difference is scope. BND's Bloomberg Aggregate index is a broad market benchmark that weights heavily toward government and mortgage-backed securities (typically 40–50% combined), with corporates making up roughly 25–30%. LQD's iBoxx index holds only corporate bonds, giving it zero exposure to Treasuries or agencies and concentration in corporate credit. This explains the yield gap: LQD's 4.21% distribution rate beats BND's 4.01%, but that premium comes from credit risk, not duration—LQD's beta of 1.33 is noticeably higher than BND's 0.98, meaning it swings harder with interest rates and corporate credit spreads. On the cost side, BND's 0.03% expense ratio is among the cheapest in fixed income, while LQD's 0.14% is still low but reflects its narrower focus. Size matters too: BND's $158B in AUM dwarfs LQD's $29.2B, which can mean tighter bid-ask spreads and deeper liquidity for BND.
Who each is best for
BND: Fits investors seeking a simple, low-cost core bond holding that captures the full U.S. fixed-income market, with minimal credit risk and stable intermediate duration. Works well as a ballast for equity portfolios or as a standalone allocation to bonds for those who want to avoid picking among bond types.
LQD: Fits investors comfortable with corporate-credit exposure who want to tilt toward higher-yielding corporate bonds within an investment-grade framework, or who view corporate credit spreads as attractive relative to Treasuries at a given point in the rate cycle.
Key risks to know
- Credit spread widening. LQD's exclusive focus on corporates means its NAV is much more sensitive to investment-grade credit-spread blowouts than BND, which has duration and agency/Treasury buffers to cushion spread moves.
- Interest-rate risk at different durations. The two funds track indexes with materially different duration profiles—the Aggregate is shorter-duration on average than a pure corporate index—so rising-rate environments will hit LQD harder despite both funds holding investment-grade bonds.
- Mortgage extension risk in BND. A significant portion of BND's holdings are mortgage-backed securities, which exhibit negative convexity and can see their effective duration lengthen in a rising-rate scenario, creating reinvestment headwinds.
- Liquidity and concentration in LQD. While investment-grade corporates are liquid, LQD's narrower universe (roughly 700 bonds vs. BND's 12,000+) means less diversification and potential for larger mark-to-market moves in dislocated credit environments.
Bottom line
If you want maximum diversification and the lowest cost, BND's broad market exposure and 0.03% expense ratio stand out; if you're willing to accept corporate-credit concentration for modestly higher yield and don't mind higher volatility, LQD's tilt toward corporate spreads offers an alternative. Both are liquid, low-cost ETFs, but they serve different roles in a fixed-income allocation. Past performance doesn't predict future results.
