McFadden's main official legacy was the working on and the passing of the McFadden Act of 1927, limiting nationally-chartered branch banks to the state in which the main branch operates. The Act sought to give national banks competitive equality with state-chartered banks by letting national banks operate branch banks to the extent permitted by state law. The McFadden Act specifically prohibited interstate branching by allowing national banks to branch only within the state in which they were situated. Although the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 repealed this provision of the McFadden Act, it specified that state law continues to control intrastate branching, or branching within a state's borders, for both state and national banks.
