IBMP vs MUND

IBMPAiShares iBonds Dec 2027 Term Muni Bond ETF

MUNDCNorthern Trust 2055 Tax-Exempt Distributing Ladder 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.

MUND A municipal bond ladder in one ticket: bonds maturing on a schedule through 2055, federally tax-exempt income paid monthly, and principal handed back as rungs mature. Built to wind down by its terminal year, not run forever.

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.

MUND The Fund seeks periodic distributions of federally tax-exempt income and/or principal through 2055. It uses a laddered strategy investing in municipal debt instruments with different maturity dates through the 2055 terminal year.

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.

• MUND Works like an actual ladder: munis with staggered maturities through the 2055 terminal year, paying tax-exempt income monthly and returning principal as bonds come due.
• Costs 0.18% a year, below the 0.30% median for muni bond ETFs. Cheap for a structured, dated strategy rather than a plain index scoop.
• Spreads the rungs across about 100 US municipal positions, so no single issuer or maturity carries the ladder.

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.

• MUND Payouts blend tax-exempt interest with returned principal, and return of capital is disclosed. The distribution is not all yield, and net asset value is designed to shrink toward 2055.
• Launched in 2025, still small and thinly traded. Wider bid-ask spreads are the trade-off for a niche structure this new.
• Without the 2055 end date, broad muni staples are cheaper and far more heavily traded: VTEB at 0.03% and MUB at 0.05%.
