A bank authorized in a specific state by a state-based charter, with generally the same functions as a national bank.
In the United States, a bank that has received its charter from a state government rather than the federal government. A state bank has the option of whether or not to become a member bank in the Federal Reserve System. If it elects to become a member, there is no real difference between a state bank and a federal bank, except that the state bank generally does business only within a state. If it does not become a member, it is regulated only by the state in which it is based. See also: Nonmember Bank.
