American Bankers AssociationFounded in 1875 and based in Washington, DC, the American Bankers Association brings together banks of all sizes and charters into one association. ABA works to enhance the competitiveness of the nation's banking industry and strengthen America's economy and communities. Its members – the majority of which are banks with less than $125 million in assets – represent over 95 percent of the industry's $13.3 trillion in assets and employ over 2 million men and women.
