AllianceBernstein Municipal Fund Reveals April Portfolio Snapshot
Benzinga reported Thursday that the AllianceBernstein National Municipal Income Fund (NYSE: AFB) published its monthly holdings disclosure covering the period ending April 30. The update offers investors a detailed look at the closed-end fund’s fixed-income positioning across U.S. municipalities.
Top Holdings Tilt Toward Infrastructure Debt
The AllianceBernstein municipal fund’s single largest position was a San Francisco International Airport revenue bond. That issue, carrying a 5.50% coupon and maturing in 2055, represented roughly 3.72% of the total portfolio. A Melissa, Texas, independent school district bond came in second at 2.16%. A Commonwealth of Massachusetts general obligation issue rounded out the top three at 2.00%.
Other notable top-ten positions included debt from the Oklahoma Turnpike Authority, the New York Transportation Development Corporation, and the Dallas Independent School District. Several metropolitan airport authorities also appeared prominently, including Atlanta, Hawaii, and the Washington area. The presence of multiple airport-linked issues underlines the fund’s appetite for long-duration infrastructure paper.
Sector Breakdown Highlights Aviation Dominance
Airport revenue bonds made up the largest sector allocation at 13.65%. Not-for-profit healthcare institutions followed at 11.04%, with miscellaneous revenue bonds accounting for another 7.51%. Toll roads and transit debt represented 5.89% of assets.

Airline-linked industrial development bonds held a 5.17% share. Prepaid energy contracts contributed 4.63%, while public primary and secondary education bonds accounted for 4.08%. Smaller allocations went to private higher education, ports, industrial development, public universities, senior living facilities, water and sewer utilities, and electric utilities.
Background on the Fund
AFB is a closed-end municipal bond fund managed by AllianceBernstein, a major asset manager overseeing hundreds of billions across global strategies. Closed-end funds issue a fixed number of shares that trade on exchanges, meaning the market price can diverge from the underlying net asset value. Municipal bonds are generally exempt from federal income tax, making them attractive to higher-bracket investors. The fund’s long average maturity profile suggests it carries meaningful interest-rate sensitivity in the current environment.
What the Update Signals
The heavy weighting toward airport and infrastructure revenue bonds reflects confidence in travel demand recovery and steady toll-road traffic volumes. The fund’s diversified issuer base across more than a dozen states limits single-geography credit risk. Investors will watch whether rate movements in the second half of 2026 prompt any rotation away from the fund’s long-duration tilt.
