IBMRAiShares iBonds Dec 2029 Term Muni Bond ETF

In short

IBMO No data

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

IBMO No data

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

Why people hold it

IBMO No data

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

IBMO No data

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.
