United States v. Philadelphia National Bank, 374 U.S. 321 (1963), also called the Philadelphia Bank case, was a 1963 decision of the United States Supreme Court that held Section 7 of the Clayton Act, as amended in 1950, applied to bank mergers. It was the first case in which the Supreme Court considered the application of antitrust laws to the commercial banking industry. In addition to holding the statute applicable to bank mergers, the Court established a presumption that mergers that covered at least 30 percent of the relevant market were presumptively unlawful.
