About MDLMX

BlackRock Short Duration Muni Fund Investor A1 Shares is an open-end municipal bond fund focused on delivering tax-exempt income with limited interest-rate sensitivity. The fund normally invests at least 80% of assets in municipal bonds and notes whose interest is exempt from federal income tax, emphasizing investment‑grade securities and short effective duration to help manage volatility from rate movements. It allocates to instruments such as variable rate demand obligations and other short- to intermediate‑tenor municipal issues, generally targeting maturities under ten years to preserve capital and maintain liquidity. Managed by BlackRock’s municipal bond team, the strategy employs rigorous credit research and active duration management to balance income generation with risk control, including use of portfolio-level measures like effective duration to assess interest-rate exposure. The fund plays a role in the market as a vehicle for investors seeking federally tax‑exempt income and lower duration risk compared with longer‑maturity municipal funds, participating across sectors such as general obligation, essential services, transportation, and healthcare within the U.S. municipal finance ecosystem.
