A city that plays a crucial role in global finance is referred to as what?

A city that plays a crucial role in global finance is known as a "world city." This term refers to cities that have significant influence on global economic and cultural affairs, and they typically host leading financial institutions, multinational corporations, and major stock exchanges. World cities are characterized by their connectivity, diversity, and ability to attract international talent and investment, making them pivotal hubs in the global economy.

While metropolitan centers are important urban areas within a country that might offer various services and amenities, they do not necessarily hold the same impact on global finance. Core cities often refer to central urban areas within a larger metropolitan region, but they may not have the global financial influence that a world city possesses. Major urban centers can be significant in their national context, yet they similarly lack the overarching global significance that defines a world city. Thus, the designation "world city" specifically highlights the city’s influence on the international stage, particularly in finance and trade.
