What government agency regulates banks?

In the United States, several government agencies regulate banks, including the Office of the Comptroller of the Currency (OCC), the Federal Reserve, and the Federal Deposit Insurance Corporation (FDIC). The OCC charters and supervises national banks, the Federal Reserve oversees monetary policy and regulates bank holding companies, while the FDIC insures deposits and supervises state-chartered banks. Each agency plays a distinct role in ensuring the safety, soundness, and stability of the banking system.
