What is a state or National Bank?

Written by Editorial Team | Last Updated: August 2026

A state bank and a national bank differ primarily in their chartering authority and regulatory oversight framework. A state bank is incorporated, licensed, and supervised by an individual state's department of banking, whereas a national bank receives its operating charter federally from the Office of the Comptroller of the Currency under the Department of the Treasury. National banks possess broad federal preemption powers that allow them to operate seamlessly across multiple state lines without securing separate state banking licenses, whereas state-chartered institutions navigate state-level banking regulations while typically maintaining federal deposit insurance through the Federal Deposit Insurance Corporation.
