Wall Street is a 0.7-mile-long (1.1 km) street running eight blocks, roughly northwest to southeast, from Broadway to South Street on the East River in the Financial District of Lower Manhattan, New York City. Over time, the term has become a metonym for the financial markets of the United States as a whole, the American financial sector (even if financial firms are not physically located there), or New York-based financial interests. Anchored by Wall Street, New York City has been called both the most economically powerful city and the leading financial center of the world, and the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. Several other major exchanges have or had headquarters in the Wall Street area, including the New York Mercantile Exchange, the New York Board of Trade, and the former American Stock Exchange.
