IBMRAiShares iBonds Dec 2029 Term Muni Bond ETF

MYMJFState Street My2030 Municipal Bond ETF

In short

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.

MYMJ A bond fund with a finish line. MYMJ holds roughly 100 municipal bonds maturing around 2030, pays monthly along the way, then distributes remaining principal and winds down around December 15, 2030.

Stated mandate

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

MYMJ The fund is actively managed and targets municipal bonds maturing primarily in 2030. It is designed to distribute remaining principal and liquidate around December 15, 2030.

Why people hold it

• 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.

• MYMJ Behaves like a single bond, not a perpetual fund: it targets munis maturing primarily in 2030 and is designed to pay out remaining principal and liquidate around December 15, 2030.ssga.com
• The municipal option on a shelf whose highest-graded names (BSCU, IBDU, IBTJ) are corporate and Treasury ladders. Different tax and issuer profile in the same defined-maturity wrapper.
• Actively managed rather than locked to a fixed list, so the team can choose among issues inside the 2030 maturity window. Spreads income across about 100 bonds and pays monthly.

Worth knowing

• 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.

• MYMJ The active approach carries an active price: 0.20% a year, roughly double the typical fee among defined-maturity bond ETFs.
• Small and thinly traded, which tends to mean wider bid-ask spreads than the big ladder franchises. Limit orders matter more here.
• The clock runs down. Launched in 2024, it shortens toward its 2030 wind-up, so its interest-rate sensitivity and income profile shift as the end date nears.
