IBMR vs MYMG

IBMRAiShares iBonds Dec 2029 Term Muni Bond ETF

MYMGDState Street My2027 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.

MYMG One dated rung of a municipal bond ladder, in ETF form: roughly 70 munis maturing in 2027, with monthly income aimed at exemption from regular federal income tax. Most target-maturity funds are corporate or Treasury. This is the tax-exempt flavor.

Stated mandate

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

MYMG The fund seeks current income exempt from regular federal income taxes while also seeking preservation of capital.

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.

• MYMG Tracks the ICE 2027 Maturity US Broad Municipal Index, so it behaves like a single dated rung of a ladder instead of a fund with permanently rolling maturities.ssga.com
• The mandate targets income exempt from regular federal income taxes alongside preservation of capital, and distributions come monthly rather than quarterly.
• Roughly 70 municipal bonds in one ticker, a basket most individual investors would struggle to assemble bond by bond in a dealer-quoted market.
• A muni option in a corner of the market dominated by corporate and Treasury bullet funds like IBDU, IBTJ and BSCT, from a long-running ETF issuer.

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.

• MYMG The 0.20% expense ratio sits above the typical target-maturity bond ETF; Treasury and corporate rungs such as IBTJ (0.07%) and BSCT (0.10%) charge less.
• Small and thinly traded, so trading costs can matter more here than in the giant corporate ladder funds. Launched in 2024, it also has a short history.
• Read the mandate literally: the exemption is from regular federal income taxes. Other tax layers are not part of the objective.
