Modern financial institutions organize their comprehensive offerings into four primary categories of banking services. Retail Banking serves individual consumers with checking accounts, savings deposits, mortgages, and personal loans. Corporate Banking caters to large enterprises, offering specialized treasury services, trade finance, and commercial credit lines. Investment Banking handles complex financial transactions, including corporate mergers, acquisitions, equity underwriting, and bond issuance. Private Banking delivers tailored wealth management, asset custody, and tax planning services exclusively to high-net-worth individuals and families.
