Written by Editorial Team | Last Updated: August 2026

The Bank of New York, founded by visionary statesman Alexander Hamilton in February 1784, holds the historic distinction of being the oldest operating bank in continuous existence within the United States. Established before the ratification of the United States Constitution or the creation of the federal monetary system, the institution provided essential financial credit to support early municipal development, commerce, and international trade in post-revolutionary Manhattan. Through centuries of economic evolution, financial panics, and world wars, the institution grew into a global custody and asset management powerhouse, eventually evolving into BNY Mellon while maintaining its foundational legacy.
