Financial services are economic services tied to finance provided by financial institutions. Financial services encompass a broad range of service sector activities, especially as concerns financial management and consumer finance.

The finance industry in its most common sense concerns commercial banks that provide market liquidity, risk instruments, and brokerage for large public companies and multinational corporations at a macroeconomic scale that impacts domestic politics and foreign relations. The extragovernmental power and scale of the finance industry remains an ongoing controversy in many industrialized Western economies, as seen in the American Occupy Wall Street civil protest movement of 2011.

Styles of financial institution include credit union, bank, savings and loan association, trust company, building society, brokerage firm, payment processor, many types of broker, and some government-sponsored enterprise.

Financial services include accountancy, investment banking, investment management, and personal asset management.
