• Making a difference in Maine’s communities for over 50 years

    The Maine Municipal Bond Bank was created in 1971 by the Maine State Legislature. The agency has an immense history of providing Maine’s cities, towns, school systems, water and sewer districts, and other governmental entities access to low cost capital funds through the sale of its highly rated tax-exempt bonds. Established as an independent agency, the Bond Bank is administered by a board of commissioners appointed by the Governor. The Bond Bank works closely with its municipal clientele to provide unique, cost effective and competitive financing programs.
