BSMW vs IBMP

BSMWCInvesco BulletShares 2032 Municipal Bond ETF

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

In short

BSMW A rung of a municipal bond ladder in ETF form: investment-grade munis effectively maturing in 2032, after which the fund winds up and pays out. One bond's end date, with well over a thousand bonds inside.

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

BSMW The Fund tracks the investment results of the Invesco BulletShares Municipal Bond 2032 Index. The index covers investment-grade, U.S. dollar-denominated municipal bonds maturing or effectively maturing in 2032.

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

• BSMW It has a finish line. The fund terminates on or about Dec. 15, 2032 and distributes proceeds, unlike an open-ended muni fund that rolls its portfolio forever.invesco.com
• Over a thousand investment-grade munis from US state, agency and local issuers, held via index sampling. Assembling that spread bond by bond is a chore.invesco.com
• Income arrives monthly, and the fund and index rebalance monthly as the portfolio walks toward its 2032 maturity year.invesco.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

• BSMW The 0.18% fee runs above the typical target-maturity bond ETF, including Invesco's own corporate BulletShares rungs like BSCT and BSCU at 0.10%.
• Thinly traded, so bid-ask spreads and order type can matter as much as the headline fee on any given trade.
• In the final year, bonds mature and the portfolio shifts into cash and cash equivalents, so the yield generally drifts toward cash yields.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.
