Overview
AGG and LQD are both iShares bond ETFs offering monthly income, but they cover different universes within investment-grade debt. AGG tracks the broad U.S. Aggregate Bond Index—a mix of government, corporate, mortgage-backed, and asset-backed securities. LQD zeros in on the investment-grade corporate bond market alone, filtering out government and securitized debt. That focus on corporate credit is what drives the 5.17% yield on LQD versus 4.25% on AGG.
How they differ
The biggest structural difference is scope: AGG holds the entire U.S. investment-grade bond market (government, agency, corporate, MBS, ABS), while LQD holds only IG corporate bonds. Because corporates carry higher credit risk than Treasuries and agencies, LQD's yield sits 0.92% percentage points higher.
AGG's 0.03% expense ratio undercuts LQD's 0.14% by a slim margin, reflecting AGG's massive $137B asset base against LQD's $27.2B. On volatility, LQD's 1.35 beta signals roughly 35% more price swing than AGG's 0.99 beta—a natural consequence of corporate credit sensitivity. Both distribute monthly, so reinvestment rhythm is identical.
Who each is best for
AGG: Fits investors seeking broad-based, government-stabilized bond exposure with minimal turnover costs. The mix of Treasuries, agencies, and corporates appeals to those building a core fixed-income anchor.
LQD: Fits investors willing to take on corporate credit sensitivity in exchange for higher current income, and those who want isolated exposure to investment-grade corporate debt without government securities dragging down yield.
Key risks to know
- Credit spread risk on LQD. IG corporate spreads widen in recession or credit stress, eroding bond prices and distributions. AGG's Treasury and agency holdings provide a cushion; LQD has none.
- Duration mismatch between the funds. LQD's corporate bond mix typically carries different maturity and duration profiles than AGG's broader index, so they won't move in tandem during rate cycles.
- AGG's mortgage-backed security exposure. Prepayment risk in MBS can suppress returns in falling-rate environments, a headwind LQD avoids by holding only corporates.
- Reinvestment risk at current yields. Both funds distribute monthly at rates (4.25%, 5.17%) above the current risk-free rate; near-term reinvestment of those payouts may occur at lower yields if rates decline.
Bottom line
If you want a diversified, government-backed bond foundation with minimal fees, AGG stands out. If you're comfortable with corporate credit exposure and want higher income, LQD's 0.92% yield premium warrants weighing against its 1.35 beta and concentration risk. Past performance doesn't predict future results; credit conditions and rate paths will shape both funds differently over time.
