BSMV vs IBMR

BSMVBInvesco BulletShares 2031 Municipal Bond ETF

IBMRAiShares iBonds Dec 2029 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.

IBMR A muni ladder rung in one ticker: it holds investment-grade municipal bonds maturing in 2029, tracks an AMT-free index, and pays monthly. Bond-style term structure, ETF plumbing.

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.

IBMR The fund seeks to track an index of investment-grade municipal bonds that mature in 2029.

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.

• IBMR Charges 0.10% a year, right at the median for target-maturity bond funds, and the iBonds lineup is built so maturity years stack into a ladder.
• Spreads across more than a thousand investment-grade munis, so one issuer's trouble barely moves the fund.
• Follows an AMT-free index, screening out bonds whose income can trip the alternative minimum tax.
• Pays monthly, matching how muni income is usually spent, and holds a well-built portfolio for its category.

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.

• IBMR Munis are the tax-advantaged lane. For the same 2029 rung in taxable bonds, iShares also runs IBDU (corporate) and IBTJ (Treasury).
• The index is callable-adjusted: plenty of munis can be redeemed early by their issuers, so the mix heading into the term date can shift.
• It is a fund, not a single bond. Shares trade at market prices and move with rates along the way, and the end payout is whatever the bonds deliver.
