National Banking Act (1863)
Congress created a federal system for chartering national banks, giving banks the choice of answering to federal or state authority. The law also created the position that became the Comptroller of the Currency to supervise national charters.
National banks proliferated, though state banks remained dominant for years.
The dual banking system became a durable feature of U.S. finance and set the template for optional federal charters.
The GENIUS Act creates a similar federal alternative to state stablecoin regimes, letting issuers choose their regulator.
