LQD vs VTC

LQDAiShares iBoxx $ Investment Grade Corporate Bond ETF

VTCAVanguard Total Corporate Bond ETF

In short

LQD One of the first bond ETFs ever launched (2002) and still the ticker traders reach for on corporate credit. Its index takes only big, widely held investment-grade bonds, so you own the liquid end of the market.

VTC Most cheap corporate bond funds sell you one slice of the maturity curve. VTC buys the whole investment-grade corporate market, short to long, for 0.03% a year, and since 2025 it owns the bonds directly instead of stacking three Vanguard funds.

Stated mandate

LQD The fund seeks to track an index of U.S. dollar-denominated investment-grade corporate bonds.

VTC The Fund seeks to track a broad, market-weighted corporate bond index, specifically the Bloomberg U.S. Corporate Bond Index. It uses an indexing approach focused on investment-grade, fixed-rate, taxable corporate bonds.

Why people hold it

• LQD Costs 0.14% a year, under the 0.19% median for investment-grade corporate bond funds in its group.
• The index is a liquidity filter: bonds need $750M+ outstanding from issuers with $2B+ of debt, and no single issuer gets more than 3% of the basket.ihs.com
• Running since 2002 and now a multi-billion-dollar fund that trades heavily, so getting in and out is rarely the hard part.
• Tracks its benchmark closely, which is the entire job of an index bond fund, and pays interest monthly.

• VTC 0.03% a year against a 0.19% median for investment-grade corporate ETFs. On this exact Bloomberg index, nothing in the group charges less.
• One ticker, the full corporate curve. Top-graded rivals like VCIT, IGIB and IGSB each buy a single maturity band; VTC's index spans short, intermediate and long fixed-rate corporates.
• No overlays, no active tilts, no credit guesswork. Market-weighted indexing of investment-grade, fixed-rate, taxable corporates, and the portfolio hews tightly to that mandate.
• Income lands monthly, not quarterly, which matters if bond coupons are doing real work in your cash flow.

Worth knowing

• LQD Rivals run cheaper: VCIT, USIG, SPIB, IGIB and IGSB all charge 0.03% to 0.04%. You pay up here for the liquid-index rules and the trading depth.
• The index holds bonds with at least three years left and no maturity ceiling, so long-dated debt is in the mix and prices swing more when rates move.ihs.com
• This is corporate credit, not Treasuries. The rating floor is the bottom rung of investment grade (BBB-/Baa3), so credit spreads are part of the ride.ihs.com

• VTC Whole-curve means long bonds in the mix, so prices move more with interest rates than a 1-5 year slice like IGSB does.
• The plumbing changed in March 2025: Vanguard moved it from holding three underlying corporate bond ETFs to buying the index bonds directly. Same objective, same index.sec.gov
• Moderately traded rather than a volume heavyweight, so spreads can run wider than the busiest corporate bond funds, particularly in choppy markets.
