BSMU vs IBMP

BSMUCInvesco BulletShares 2030 Municipal Bond ETF

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

In short

BSMU A muni fund with an expiration date. BSMU holds municipal bonds maturing in 2030, then winds down around December 15, 2030 and pays out what's left. One rung of a muni ladder, roughly 1,800 bonds deep, in a single ticker.

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

BSMU The Fund seeks to track the Invesco BulletShares Municipal Bond 2030 Index by investing at least 80% of assets in its municipal-bond constituents. The portfolio targets U.S. municipal securities with effective maturities in 2030 and is scheduled to terminate around December 15, 2030.

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

• BSMU Behaves like a bond, trades like a fund: holdings target effective maturities in 2030 and the fund is scheduled to terminate around December 15, 2030. Most bond ETFs never mature.
• Roughly 1,800 municipal bonds inside, so no single issuer dominates the outcome. Assembling that ladder rung yourself takes real size and a bond desk.
• Income arrives monthly, and the fund has been running since 2020 as part of Invesco's BulletShares dated-maturity lineup, so rungs can be stacked across years.

• 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

• BSMU 0.18% a year sits above much of the dated-maturity crowd; Invesco's own 2030 corporate version, BSCU, charges 0.10%. Muni bonds are pricier to source and hold.
• The end date cuts both ways: once the fund terminates around December 15, 2030, the cash comes back and the reinvestment decision is yours.
• Moderately traded rather than a category heavyweight, so order size and timing matter more here than in the biggest bond ETFs.

• 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.
