Wall Street is a street in the Financial District of Lower Manhattan in New York City. Eight city blocks long, it runs between Broadway in the west and South Street and the East River in the east. The term "Wall Street" has become a metonym for the financial markets of the United States as a whole, the American financial services industry, New York–based financial interests, or the Financial District itself. Anchored by Wall Street, New York has been described as the world's principal fintech and financial center.
