BSMZ vs IBMQ

BSMZCInvesco BulletShares 2035 Municipal Bond ETF

IBMQAiShares iBonds Dec 2028 Term Muni Bond ETF

In short

BSMZ A single rung of a municipal bond ladder, wrapped in an ETF. It holds roughly 1,400 munis, then terminates around Dec. 15, 2035, giving you a bond's end date without picking the bonds yourself.

IBMQ A muni ladder rung in ETF form: thousands of investment-grade bonds that mature or get called by late 2028, then the fund winds up and pays out. AMT-free index, income paid monthly.

Stated mandate

BSMZ The fund seeks exposure to US dollar-denominated municipal securities from U.S. states, state agencies, and local issuers, targeting bonds maturing in 2035 and terminating around Dec. 15, 2035.

IBMQ The fund seeks to track an index of investment-grade U.S. municipal bonds that are expected to mature or be redeemed before December 2, 2028.

Why people hold it

• BSMZ Defined maturity: it targets bonds maturing in 2035 and terminates around Dec. 15, 2035. An end date, not an evergreen fund that rolls on forever.invesco.com
• Roughly 1,400 positions from US states, state agencies and local issuers, so no single borrower carries the portfolio. The holdings are the strongest part of the package.
• Invesco has run the BulletShares playbook for years, and its corporate rungs (BSCT, BSCU) sit among the best-executed funds in the target-maturity group.

• IBMQ Acts like a single bond with a known end date: it holds munis maturing or redeemed before December 2, 2028, then terminates and distributes net assets.ishares.com
• Spreads one ladder rung across thousands of investment-grade municipal bonds, far more than a retail buyer could assemble directly, and pays monthly.
• The tracked index is AMT-free, screening out bonds whose interest counts toward the alternative minimum tax.
• Costs 0.10% a year, in line with the typical target-maturity bond fund, and this 2028 rung has been running since 2019.

Worth knowing

• BSMZ At 0.18% a year, it runs above the typical target-maturity bond fund. Fee drag bites harder when the underlying yields are muni-sized.
• Launched in 2025 and thinly traded so far. Thin volume tends to mean wider spreads, which is what limit orders are for.
• Distributions land on an irregular schedule rather than a fixed monthly rhythm, so the income stream needs more watching than a clockwork payer.

• IBMQ Callable-adjusted by design: munis can be redeemed early, so cash can come back ahead of schedule and the final wind-up payout is not a fixed number.
• Until it terminates it trades like any bond fund, with prices moving on rates, and volume is moderate rather than heavy.
• Same 0.10% as corporate rungs like IBDU and BSCT, while Treasury rungs such as IBTJ run cheaper at 0.07%; the muni tax treatment is the reason to pay it.
