It is a defined-maturity ETF composed of U.S. investment-grade municipal bonds that mature in 2027. The fund gathers municipal bonds with similar maturity dates, holds them, and liquidates at maturity, seeking interest income exempt from federal taxes.

It is suited for investors who want to invest in tax-advantaged municipal bonds aligned with a 2027 target date and hold the position through maturity.

The ETF is managed by Invesco using a passive (index-tracking) approach.

The fund uses a defined-maturity structure that pools U.S. investment-grade municipal bonds maturing in 2027, holds them, and liquidates at maturity. It pursues tax-advantaged interest income exempt from federal taxes and replicates at the ETF level the characteristics of individual bonds, whose duration shortens over time and whose principal is repaid at maturity.

• Holds municipal bonds aligned with a 2027 maturity
• Combines federal tax exemption with maturity liquidation

Assets under management (AUM) stand at $373.5M, and the total expense ratio is 0.18% annually.

The key comparison point versus perpetual municipal bond ETFs such as MUB and VTEB is the defined maturity and maturity liquidation structure.

Defined-maturity municipal bond ETFs see prices move with rate direction, but as maturity approaches, duration shortens and interest-rate sensitivity declines. Holding through maturity is expected to deliver results close to the projected return, regardless of interim price swings.

For defined-maturity municipal bonds, flows shift with demand for tax benefits, the rate cycle, and maturity-matching needs. Demand for in-state tax advantages and maturity matching adds to these flows, sometimes moving money into related products. Interim performance can also differ depending on the rate environment, a point worth reviewing.

Federal tax savings and maturity matching are strengths, while interim rate risk, state-tax non-exemption, and post-maturity reinvestment are considerations.

For exposure to short-term municipal bonds without a fixed maturity, direct alternatives include SUB, and for other short-term municipal bond options, products such as SHM can also be compared. For defined-maturity municipal bonds with a different maturity, products such as IBMR can also be reviewed alongside. The three products shown in the table—MUB, VTEB, and JMUB—are municipal bond strategies run without a defined maturity, so they differ from the defined-maturity structure. This ETF differentiates itself through municipal bond holdings aligned with a 2027 maturity.

Here are the points to review before investing in BSMR. Federal tax savings and maturity matching are attractive, but interim rate risk, state-of-residence tax treatment, and post-maturity reinvestment should be confirmed in advance. It is also advisable to compare with municipal bond products that operate without a maturity constraint.

Pre-maturity rate increases and the state tax burden of the state of residence are the main variables affecting interim performance, and selling before maturity exposes investors to price swings. After the 2027 maturity, a separate reinvestment vehicle must be found.

This is a suitable candidate for investors who want to invest in tax-advantaged municipal bonds aligned with a 2027 target date. For exposure to municipal bonds without a maturity constraint, products such as MUB and VTEB are appropriate, while for maturity matching, holding this fund through maturity is the recommended approach.
