IBDZ vs VBCC

IBDZBiShares iBonds Dec 2034 Term Corporate ETF

VBCCAVanguard Target Maturity 2029 Corporate Bond ETF

In short

IBDZ A far rung on the iBonds corporate ladder: roughly 400 investment-grade corporate bonds that all mature in 2034, in one ticker with a built-in end date. Ladder discipline, no CUSIP shopping.

VBCC Vanguard's version of a single rung on a bond ladder: investment-grade corporates that all mature in 2029, wrapped in an ETF at 0.08% a year, under the typical fee in the target-maturity aisle.

Stated mandate

IBDZ The fund seeks to track an index of investment-grade corporate bonds maturing in 2034.

VBCC The fund seeks to follow a market-weighted index of U.S.-dollar-denominated, investment-grade corporate bonds scheduled to mature in 2029.

Why people hold it

• IBDZ Built like a bond, traded like a fund: it tracks the Bloomberg December 2034 Maturity Corporate Index and terminates at the end of its term year instead of rolling on forever.
• 0.10% a year, right at the middle of the target-maturity crowd, and it holds about 400 investment-grade corporates so no single issuer runs the show.
• Pays monthly, which suits people stacking rungs for a known future expense rather than watching a quarterly calendar.
• Tracking has been tight against its stated index, and the fund sits in the upper half of a target-maturity field of well over 100 competitors.

• VBCC At 0.08% a year it undercuts the target-maturity median and the established 2029 corporate rungs from iShares (IBDU) and Invesco (BSCT), both at 0.10%.
• Every bond in the index is scheduled to mature in 2029, so the portfolio has an end date instead of rolling on forever like a standard bond fund.
• Investment-grade US dollar corporates, market-weighted. No high-yield sleeve, no manager leaning on favorite issuers.
• Stacks up among the stronger builds in a crowded target-maturity field, on the back of low cost and a straightforward investment-grade portfolio.

Worth knowing

• IBDZ A 2034 maturity means far more interest-rate sensitivity than the near rungs of the same ladder, like the 2029 vintage (IBDU). Longer wait, bigger price swings along the way.
• Corporate credit, not government paper. Downgrades and defaults are live risks here in a way they are not for the Treasury version of the same ladder (IBTJ).
• Launched in 2024, so the track record is short, and it is moderately traded rather than a volume monster. Limit orders are your friend.

• VBCC Launched in 2026, so live history is short and it trades less actively than the long-running iShares and Invesco ladders. Limit orders matter more here.
• Corporate credit, not Treasuries. An investment-grade issuer can still be downgraded or miss a payment, and a 2029 maturity date does not erase that.
• Income is paid quarterly, so cash arrives four times a year rather than monthly.
