IBDT vs MYCI

IBDTAiShares iBonds Dec 2028 Term Corporate ETF

MYCIDState Street My2029 Corporate Bond ETF

In short

IBDT Acts more like a bond than a bond fund: roughly 700 investment-grade corporate bonds that all mature in 2028, wrapped in one ticker with a defined end date. Built for ladder rungs, monthly distributions and a known finish line.

MYCI A ladder rung with a driver at the wheel. MYCI holds corporate bonds maturing in 2029, pays out remaining principal and winds down around December 15, 2029, and it is actively run rather than built off an index like most target-maturity funds.

Stated mandate

IBDT The fund seeks to track an index of investment-grade corporate bonds maturing in 2028 and is designed to support income generation, bond-ladder construction, and interest-rate-risk management through a defined maturity.

MYCI The fund is actively managed to invest primarily in corporate bonds maturing in 2029. It is designed to distribute remaining principal and liquidate around December 15, 2029.

Why people hold it

• IBDT The defined 2028 maturity does the work: one ticker behaves like a ladder rung, no hunting down individual bonds or tracking each one's maturity.ishares.com
• About 700 investment-grade corporate bonds inside, so no single issuer carries the outcome the way it would in a handful of hand-picked bonds.
• Costs 0.10% a year, right at the typical fee for target-maturity bond funds, and it is one of the more actively traded names in that group.
• Launched in 2018 and now a multi-billion-dollar fund, it ranks among the strongest implementations in the target-maturity bond group.

• MYCI Behaves like a bond, not a forever fund: it holds corporate paper maturing in 2029, then distributes remaining principal and liquidates around December 15, 2029, giving you a known end date to plan around.ssga.com
• Actively managed against the ICE 2029 Maturity US Corporate Index, so the team can shop for issues rather than buy the index wholesale. Roughly 190 bonds spread issuer risk across the rung.
• Coupons come through monthly, a steady cadence while the 2029 wind-down date approaches.
• Sits in the upper half of a crowded target-maturity field, and its portfolio hews tightly to the 2029 corporate mandate it advertises.

Worth knowing

• IBDT Vanguard's VBCB targets the same 2028 corporate maturity for 0.08%, two basis points cheaper.
• This is corporate credit, not Treasuries. The bonds are investment grade, but downgrades and defaults are still part of the picture.
• It has a finish line. When the 2028 term ends the strategy is over, so the what-next decision lands back with you.ishares.com

• MYCI At 0.15% it runs above index-built 2029 rungs like IBDU and BSCT at 0.10%. That gap is the fee for an active manager on a short, plain slice of the bond market.
• A small, lightly traded fund launched in 2024, so bid-ask spreads can run wider than at the giant index ladders and the track record is still short.
• These are corporate bonds, so credit risk rides along. The final payout reflects what the portfolio holds at wind-down, not a fixed face value like a single bond you hold to maturity.
