The Financial District of Lower Manhattan, also known as FiDi, is a neighborhood located on the southern tip of Manhattan Island, where the City of New York itself originated in 1624. The district comprises the offices and headquarters of many of the city’s major financial institutions, including the New York Stock Exchange and the Federal Reserve Bank of New York. Anchored on Wall Street in the Financial District, New York City has been called both the most financially powerful city and the leading financial center of the world, and the New York Stock Exchange is the world’s largest stock exchange by total market capitalization. Several other major exchanges have or had headquarters in the Financial District, including the New York Mercantile Exchange, NASDAQ, the New York Board of Trade, and the former American Stock Exchange.
