The McFadden Act is a United States federal law, named after Louis Thomas McFadden member of the United States House of Representatives and Chairman of the United States House Committee on Banking and Currency, enacted in 1927 from recommendations made by the comptroller of the currency Henry May Dawes.
The Act sought to give national banks competitive equality with state-chartered banks by letting national banks Branch to the extent permitted by state law. The McFadden Act specifically prohibited interstate branching by allowing each national bank to branch only within the state in which it is 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 Although the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994  repealed this provision of the McFadden Act, it specified that state law continues to control intrastate branching, or branching within a state's borders, for both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.
