BSMV vs IBMP

BSMVBInvesco BulletShares 2031 Municipal Bond ETF

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

In short

BSMV BulletShares brought bond-ladder math to ETFs, and this is the municipal rung: roughly 1,500 muni bonds tracking a 2031-dated index, paying monthly. One dated slice you can stack with other years instead of buying bonds one at a time.

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

BSMV The fund seeks exposure to a portfolio of U.S.-dollar municipal securities through its index and invests at least 80% of total assets in municipal bonds included in 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

• BSMV Defined-maturity design. It tracks a single dated index (Municipal Bond 2031), so it behaves like one rung of a ladder rather than a perpetual bond fund with drifting duration.
• Roughly 1,500 municipal bonds under the hood. That is deep issuer spread for a single-year basket, and it is one of the better-diversified portfolios in its target-maturity peer group.
• The mandate is tight: at least 80% of total assets in municipal bonds from its index, per the fund's own documents. Little room to wander into other asset classes.invesco.com
• Distributions land monthly, and the fund has been running since 2021 inside Invesco's established BulletShares lineup.

• 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

• BSMV At 0.18%, it costs nearly double the 0.10% median of its target-maturity cohort, including Invesco's own corporate rungs BSCT and BSCU at 0.10%.
• It is one of the quieter tickers in a crowded field, and thin trading tends to mean wider spreads. Limit orders matter more here than on the lineup's corporate rungs.
• Measured against the whole target-maturity group, it sits in the lower half, mostly on cost and tradability rather than on how the portfolio is built.

• 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.
