IBCB vs VBCA

IBCBCiShares iBonds Dec 2036 Term Corporate ETF

VBCAAVanguard Target Maturity 2027 Corporate Bond ETF

In short

IBCB A bond ladder rung with a date stamped on it: IBCB holds roughly 300 investment-grade corporate bonds that all come due in 2036, so the term ends when the bonds do.

VBCA Vanguard showed up late to the bond-ladder aisle and priced it accordingly: one rung of investment-grade corporate bonds, all maturing in 2027, wrapped in an ETF at 0.08%.

Stated mandate

IBCB The fund seeks to track an index of U.S.-dollar-denominated, investment-grade corporate bonds maturing in 2036.

VBCA The fund seeks to track a market-weighted index of U.S.-dollar-denominated, investment-grade corporate bonds that mature in 2027.

Why people hold it

• IBCB Every bond in the basket is slated to mature in 2036, giving the portfolio a defined end date instead of rolling on forever like a standard corporate bond fund.
• Charges 0.10% a year and spreads it across roughly 300 investment-grade corporate issues tracked by the Bloomberg December 2036 Maturity Corporate Index.
• Pays quarterly, and the index keeps the credit box to investment grade rather than reaching into junk for extra income.
• One rung in the wider iBonds shelf: nearer-dated siblings such as IBDU (2029) sit among the strongest names in this cohort, so whole ladders live in one family.

• VBCA At 0.08%, it undercuts the target-maturity norm, where iShares iBonds and Invesco BulletShares rungs run 0.10%.
• Its bonds are scheduled to mature between January 1 and December 15, 2027, and the index has a planned liquidation around that date, so duration winds down instead of resetting forever.sec.gov
• Market-weighted and investment-grade only: a single maturity year spread across the US corporate market rather than a handful of hand-picked bonds.
• Stands among the stronger implementations in a crowded target-maturity group, on cost and portfolio discipline.

Worth knowing

• IBCB It launched in 2026, so the live record is short and any read on its risk behavior rests on limited history.
• A 2036 maturity is a long rung. Prices move more with interest rates than short-dated funds like the 2028 and 2029 vintages do.
• The 0.10% fee matches the typical target-maturity bond fund rather than undercutting it (VBCB runs 0.08%), and this one trades moderately, so limit orders are standard practice.

• VBCA Launched in 2026 and still small, it trades thinly; spreads can be wider than on established bond ETFs.
• Corporate credit, not Treasuries: downgrades and defaults come with the territory. Treasury-only rungs such as IBTJ sidestep that risk.
• Short operating history, so there is limited data so far on how closely it tracks its index.
