SPDR SSGA My2031 Municipal Bond ETF (MYMK) is an actively managed exchange-traded fund that seeks to maximize current income exempt from regular federal income taxes while preserving capital through a target-maturity municipal bond strategy. The fund primarily invests at least 80% of its net assets in investment-grade, USD-denominated municipal bonds maturing in 2031, including those with embedded issuer call options falling within that year; it employs a held-to-maturity approach focused on U.S. state and local government issuers such as school districts, public school authorities, transportation authorities, and electric revenue bonds. Key holdings include Johnson County Kansas Unified School District No. 233 bonds at approximately 5.98%, Connecticut ST Special Tax Oblig Rev at 5.69%, Alabama ST Public School & College Authority bonds at 4.89%, and others from Henry County GA, Delaware Transn Auth, Illinois ST, Energy Northwest WA, Hennepin County MN, Iowa Fin Auth, and Washington ST.
Launched on September 16, 2025, and sponsored by State Street Global Advisors (SSGA), a division of State Street Global Advisors headquartered at State Street Bank and Trust Company, One Lincoln Street, Boston, MA 02111, the ETF operates within the municipal target-maturity segment targeting income-focused investors seeking tax-exempt yields. With assets under management of approximately $5.01 million as of late 2025, a gross expense ratio of 0.20%, and 46 holdings predominantly in municipal bonds (99.38%) with minimal cash equivalents (0.62%), MYMK trades on U.S. exchanges and emphasizes liquidity and income generation over broad market indexing.
In recent developments, MYMK declared a dividend with an ex-date of December 1, 2025, marking an early distribution event for investors following its launch; it was introduced alongside the SPDR SSGA My2035 Corporate Bond ETF as part of SSGA's expansion into actively managed target-maturity bond strategies to provide customizable fixed-income solutions. The fund remains in its nascent phase with no reported acquisitions, partnerships, or major portfolio shifts beyond initial ramp-up, reflecting its focus on steady income accrual toward the 2031 target maturity.
