BSMY vs IBMP

BSMYCInvesco BulletShares 2034 Municipal Bond ETF

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

In short

BSMY A single-year rung on a muni ladder: roughly 2,000 bonds from US states, agencies and local governments, all effectively maturing in 2034, bundled into one ticker on Invesco's BulletShares shelf.

IBMP A single rung of a muni ladder in one ticker: investment-grade bonds that all mature in 2027, tax-exempt income paid monthly along the way, and a defined end date instead of a fund that rolls on forever.

Stated mandate

BSMY The Fund invests at least 80% of its assets in municipal bonds represented by its index, which covers U.S.-dollar municipal securities issued by U.S. states, state agencies, or local governments and maturing effectively in 2034.

IBMP The fund seeks to track an index of investment-grade municipal bonds maturing in 2027. It is designed to provide tax-exempt income, support bond-ladder construction, and manage interest-rate risk through a defined maturity.

Why people hold it

• BSMY Defined end date instead of an open-ended blob. The index holds only municipal bonds effectively maturing in 2034, so the portfolio's clock winds down like a single bond's.invesco.com
• Roughly 2,000 issues spread across states, state agencies and local governments, so no single borrower carries the fund.
• Pays monthly, which suits people who like income arriving on the same rhythm as their bills.
• Sits in the upper half of a large target-maturity peer group, with broad bond-level diversification doing much of the heavy lifting.

• IBMP Built to act like a bond, not a bond fund: the portfolio matures in 2027 and the whole design points at that date, which is what makes ladder-building possible with one trade.ishares.com
• 0.10% a year, right at the typical target-maturity bond fund, and it tracks an AMT-free index, so the tax-exempt income isn't pulled back in by the alternative minimum tax.
• Roughly 1,800 municipal bonds, so no single issuer carries the fund. That spread is hard to replicate buying individual munis one CUSIP at a time.
• Income lands monthly, and this 2027 rung has been running since 2019, so it isn't a fresh launch built for the moment.

Worth knowing

• BSMY 0.18% a year runs above the target-maturity median and above corporate BulletShares rungs like BSCT and BSCU at 0.10%.
• Trades thinly, so spreads can widen. Limit orders and steering clear of the opening and closing minutes matter more here than in a heavily traded fund.
• Launched in 2024, so there is only a short history behind it and a long stretch before the 2034 maturity year arrives.

• IBMP The 0.10% fee is the category median, not a discount. Treasury and corporate rungs like IBTJ (0.07%) and VBCB (0.08%) cost less, though neither pays tax-exempt muni income.
• The tax exemption is the entire pitch, and it does no work inside an IRA or 401(k), where the income is already sheltered.
• Trading is moderate rather than heavy, so order size and timing matter more here than in the most heavily traded bond ETFs.
