Banking groups are collections of financial institutions that operate under a common brand or ownership. They typically include various types of banks, such as commercial banks, investment banks, and savings banks, which provide a range of services like loans, deposits, and investment products. This structure allows them to diversify their offerings and manage risks more effectively. These groups often have a centralized management system that oversees the operations of their member banks. By pooling resources and expertise, banking groups can achieve economies of scale, improve customer service, and enhance their competitive position in the financial market. Examples of banking groups include JPMorgan Chase and HSBC.
