IBMP vs MYMH

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

MYMHFState Street My2028 Municipal Bond ETF

In short

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.

MYMH A single rung of a municipal bond ladder, wrapped in an ETF: a compact basket of bonds maturing in 2028, hand-picked rather than index-cloned, paying federally tax-exempt income monthly until the fund winds up around December 15, 2028.

Stated mandate

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.

MYMH The fund is an actively managed target-maturity municipal bond strategy focused primarily on bonds maturing in 2028. It seeks federally tax-exempt current income and capital preservation, and plans to liquidate around December 15, 2028.

Why people hold it

• 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.

• MYMH Built with an end date. The fund plans to liquidate around December 15, 2028, so the position resolves to cash like a maturing bond instead of rolling on forever.ssga.com
• Income is federally tax-exempt and paid monthly, so the cash arrives on a steady rhythm rather than quarterly.ssga.com
• The dated-maturity aisle is mostly index corporate and Treasury ladders (IBDU, BSCT, VBCB). This one is munis, actively managed against an ICE 2028 maturity muni index.

Worth knowing

• 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.

• MYMH At 0.20% a year, it costs about double the top-ranked ladders in its group, which sit near 0.07% to 0.10%. Active muni selection is what you get for the difference.
• A small fund that trades lightly, so bid-ask spreads can be wider than the household-name ladders. Limit orders matter more here.
• Launched in 2024, and the prospectus discloses that distributions can include return of capital, meaning part of a payout may be your own money coming back.ssga.com
