Overview
AGG and LQD are both broad bond ETFs from iShares, but they track different universes of the U.S. fixed-income market. AGG holds the full U.S. aggregate bond market—Treasuries, investment-grade corporates, and mortgage-backed securities—while LQD focuses exclusively on investment-grade corporate bonds. The yield difference reflects that tighter corporate credit exposure.
How they differ
AGG and LQD's core distinction is scope: AGG's Bloomberg U.S. Aggregate index spans government, corporate, and securitized debt, while LQD's Markit iBoxx index holds only investment-grade corporate bonds. That's why LQD yields 4.53% versus AGG's 4.00%—corporates pay more than Treasuries. LQD also carries higher beta (1.33 vs. 0.99), meaning it swings more sharply when rates move or credit spreads widen. AGG's $136B in AUM dwarfs LQD's $29.2B, and AGG's expense ratio (0.03%) is roughly one-fifth of LQD's (0.14%), though both are cheap in absolute terms.
Who each is best for
AGG: Fits investors seeking a market-weight bond foundation with minimal rate or credit risk relative to the broad market. The monthly distribution and low cost suit long-duration income portfolios where diversification across bond types is a priority.
LQD: Fits investors comfortable tilting toward corporate credit and willing to accept higher volatility in exchange for yield pickup. Useful for allocations where the investor believes credit spreads offer value or prefers corporate-only exposure over government bonds.
Key risks to know
- Interest rate risk: LQD's higher beta means its NAV falls more sharply when yields rise. A 1% rate increase would pressure LQD more than AGG, though both face directional rate risk.
- Credit spread risk: LQD holds no Treasuries or mortgage-backed securities to cushion when corporate spreads widen. In a credit event or recession, LQD could lag AGG by several percentage points.
- Concentration in corporates: LQD's focus on a single credit segment creates hidden correlation risk; diversification across issuer quality is tighter than AGG's mix of government, agency, and corporate debt.
- Expense drag over time: LQD's 0.14% ratio costs roughly $14 annually per $10,000 invested versus AGG's $3—a small difference yearly but meaningful over decades.
Bottom line
If you want broad market bond exposure with minimal cost and maximum diversification, AGG's all-inclusive approach stands out. If you're targeting corporate credit specifically and willing to tolerate higher rate sensitivity in exchange for extra yield, LQD offers that tighter focus. Past performance does not guarantee future returns; credit conditions and Fed policy will shape both funds' behavior going forward.
