Financial hubs are cities or regions that serve as central points for financial services and activities. They host a concentration of banks, investment firms, and other financial institutions, facilitating trade, investment, and economic growth. Examples of well-known financial hubs include New York City, London, and Hong Kong. These hubs attract businesses and talent from around the world due to their robust infrastructure, regulatory frameworks, and access to capital. They play a crucial role in global finance by providing services such as asset management, insurance, and foreign exchange, thereby influencing economic trends and policies internationally.
