BSMT vs IBMP

BSMTBInvesco BulletShares 2029 Municipal Bond ETF

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

In short

BSMT A 2029 rung of a municipal bond ladder, wrapped in an ETF. It holds roughly 1,900 munis that all mature around the same time, then terminates in December 2029 and pays out: a bond-like ending with fund-like diversification.

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

BSMT The fund seeks to track an index measuring US dollar-denominated municipal securities issued by states, state agencies, and local governments. It invests at least 80% of assets in municipal bonds comprising that index.

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

• BSMT Real end date. The fund is built to terminate on or about Dec. 15, 2029 and make a final distribution, so it behaves like a maturing bond instead of a portfolio that rolls forever.invesco.cominvesco.com 2
• Roughly 1,900 municipal bonds from states, state agencies and local governments, so no single issuer carries the rung. Buying that spread of individual munis yourself is a chore.
• Muni interest is generally free of federal income tax, and the fund pays monthly rather than on scattered bond coupon dates.prnewswire.com
• Part of the original 2019 muni BulletShares launch, the suite that brought defined maturity to munis. Ladder plumbing with years of live track record behind it.prnewswire.com

• 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

• BSMT At 0.18%, the fee sits above the target-maturity cohort median of 0.10%, and above Invesco's own 2029 corporate rung BSCT at 0.10%. Munis cost more to assemble; you pay for it.
• Unlike a single bond, the payout mix is not fixed upfront: Invesco notes income distributions vary and the split between distributions and liquidation proceeds is not predictable at purchase.invesco.com
• One maturity year, one slice of the curve. Invesco designs these to be stacked across years into a ladder, not used as a standalone core muni holding.invesco.com

• 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.
