Overview
AGG, BND, LQD, and VCIT are all fixed-income ETFs tracking investment-grade U.S. bond indexes, but they differ in breadth and composition. AGG and BND hold the broad U.S. aggregate bond market—Treasuries, agencies, investment-grade corporates, and mortgage-backed securities. LQD and VCIT focus on investment-grade corporate bonds alone, with LQD tracking liquid corporate issuers across all maturities and VCIT holding intermediate-term corporates. This distinction creates a yield and duration tradeoff: broader funds offer lower yield and lower volatility; corporate-focused funds pay more but carry credit and interest-rate risk.
How they differ
The largest difference is composition: AGG and BND are broad-market funds holding roughly 40% Treasuries, 35% mortgage-backed securities, 20% corporates, and 5% agencies, while LQD and VCIT isolate investment-grade corporate bonds. This explains the yield gap—AGG distributes 4.25% and BND 4.26%, versus LQD at 5.17% and VCIT at 5.23%.
Second, maturity focus: BND and AGG are duration-agnostic, holding bonds across all maturities. VCIT explicitly targets intermediate-term corporates (3–10 years), a narrower window than LQD, which includes corporates of any maturity. VCIT's beta of 1.07 reflects moderate interest-rate sensitivity; LQD's 1.35 is notably higher, signaling greater price swings from rate moves.
Third, cost and scale: AGG and BND both charge 0.03%, the lowest tier, and have the largest asset bases ($137B and $162B respectively). VCIT costs the same 0.03%, but LQD is costlier at 0.14%, reflecting its narrower, more specialized mandate. VCIT commands $67.3B in assets, while LQD holds $27.2B.
Who each is best for
AGG: Investors seeking maximum diversification across the entire U.S. bond market with the lowest yield in exchange for exposure to Treasury, agency, and mortgage volatility. Fits portfolios where bond allocation serves as a ballast to equities rather than income generation.
BND: Fits the same broad-market intent as AGG, using a float-adjusted index that may weight active corporate issuers differently. Useful for investors indifferent to the minor index-tracking differences and favoring Vanguard's fund infrastructure.
LQD: Designed for investors comfortable with corporate credit risk and willing to hold liquid, investment-grade corporate bonds across the yield curve in exchange for higher current income. Works well for those overweighting credit exposure within a fixed-income sleeve.
VCIT: Fits investors seeking corporate yield without excessive duration risk, favoring a disciplined intermediate-term maturity ladder. Useful for those balancing income generation with moderate interest-rate sensitivity.
Key risks to know
- Credit spread risk: LQD and VCIT depend heavily on the corporate credit environment. Widening spreads during recessions or credit stress can depress NAV even if bond values don't default. AGG and BND are less exposed, since Treasuries and agency/MBS holdings don't carry issuer credit risk.
- Duration and interest-rate sensitivity: All four move inversely to Treasury rates, but LQD's 1.35 exposes it to larger price swings than VCIT's 1.07 or the aggregate funds' near-unity betas. Rising rates will compress all NAVs; falling rates benefit LQD and VCIT more.
- Maturity and extension risk: VCIT's intermediate-term constraint may feel less volatile than broader corporate funds, but if rates remain elevated, investors face the choice of holding to maturity or realizing losses if they exit early. LQD, holding longer-dated corporates, carries greater extension risk in a high-rate regime.
- Concentration in mortgage-backed securities: AGG and BND hold roughly one-third mortgage-backed securities. Prepayment risk (borrowers refinancing when rates fall) or extension risk (when rates rise) can drag returns independently of Treasury moves.
- NAV erosion in high-yield environments: When distribution rates approach or exceed reasonable expectations for total return, funds may return capital or reduce NAV. Monitor whether payouts remain sustainable as rates stabilize and credit conditions evolve.
Bottom line
If you want maximum bond-market breadth and volatility dampening, AGG and BND are nearly identical, differing only in index methodology and issuer; the choice between them turns on preference rather than performance. If you prioritize income and accept corporate credit risk, LQD and VCIT offer higher current yield—VCIT if you want moderate interest-rate exposure, LQD if you're comfortable with longer duration. Past performance does not predict future returns; all four will trade lower if rates rise further or credit spreads widen unexpectedly.
