IBDSAiShares iBonds Dec 2027 Term Corporate ETF

VBCCAVanguard Target Maturity 2029 Corporate Bond ETF

In short

IBDS A bond fund with an expiration date. IBDS holds a basket of investment-grade corporate bonds that all mature in 2027, pays monthly along the way, then winds up around December 15, 2027 and returns remaining assets to shareholders.

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

IBDS The fund seeks to track an index of U.S. dollar-denominated, investment-grade corporate bonds maturing in 2027. It is a term fund that winds up around December 15, 2027, distributing its remaining assets to shareholders.

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

• IBDS Acts like a single bond rather than a perpetual fund: the wind-up date (around December 15, 2027) and the final distribution of remaining assets are written into the fund's own documents.
• Diversification hard to build by hand: about 700 dollar-denominated investment-grade corporate bonds in one ticker, tracking the Bloomberg December 2027 Maturity Corporate Index.ishares.com
• 0.10% a year, in line with the median target-maturity bond fund, from a lineup that has been running these dated rungs since well before this one launched in 2017.
• A multi-billion-dollar fund that trades actively and pays monthly, so the ladder rung stays liquid instead of locking you in until maturity.

• 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

• IBDS Corporate credit, not Treasuries. Issuers can be downgraded or default, and the payout at wind-up isn't fixed the way a single bond's par value is.
• Short runway. As 2027 nears, the holdings mature into cash-like assets, so the fund behaves less and less like a bond fund and more like a countdown.
• Fee is mid-pack, not low: some target-maturity rungs undercut it, including VBCB at 0.08% and IBTJ at 0.07%.

• 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.
