LQDB vs VTC

LQDBAiShares BBB Rated Corporate Bond ETF

VTCAVanguard Total Corporate Bond ETF

In short

LQDB Most investment-grade bond funds blend AAA through BBB. LQDB keeps only the BBB rung, the biggest and lowest-rated slice of the IG market, in one index fund of roughly 1,700 bonds that pays monthly.

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

LQDB The fund seeks to track an index containing U.S. dollar-denominated corporate bonds rated BBB.

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

• LQDB Pure-play BBB. It tracks an index of dollar-denominated BBB corporate bonds only, with no A or AAA paper watering down the credit exposure.ishares.com
• 0.15% a year, under the median fee in its investment-grade corporate peer group.
• Roughly 1,700 bonds behind one ticker, with income paid monthly rather than quarterly.
• Tracking has hugged the benchmark closely, one of the cleaner index implementations in its group.

• 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

• LQDB BBB is the last rung before high yield, so this concentrates the most downgrade-sensitive slice of investment grade instead of spreading across the ratings ladder.
• Small asset base and light trading volume, so bid-ask spreads can run wider than on the giant core bond ETFs.
• Broad IG funds like VCIT and USIG charge a few basis points, so the BBB-only tilt costs more than plain-vanilla corporate exposure.

• 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.
