Nuveen Municipal Income Fund Inc.

Nuveen Municipal Income Fund Inc. is a closed-end investment company focused on providing a high level of current income that is exempt from federal income tax. The fund primarily invests in U.S. municipal bonds, including general obligation and revenue-backed issues that finance public projects such as transportation, airports, healthcare facilities, and state-level infrastructure. According to the sponsor’s profile, the portfolio can allocate a significant portion to lower-rated or unrated municipal securities, with defined limits on below-investment-grade exposure, and may use tender option bonds to manage rate sensitivity and create modest effective leverage to implement its strategy. As a national municipal strategy, it spans multiple states and sectors, offering diversified exposure to the muni market and its tax-advantaged income characteristics. Public disclosures highlight a concentrated top holdings mix in transportation, airport revenue, and state tax-backed bonds, reflecting an emphasis on essential-service and large-scale infrastructure financing within the municipal universe. By aggregating diversified municipal credit, Nuveen Municipal Income Fund Inc. plays a role in channeling capital to public-purpose projects while delivering federally tax-exempt income to shareholders.
