Financial services are the economic services provided by the finance industry, which encompasses a broad range of organizations that manage money, including credit unions, banks, credit card companies, insurance companies, consumer finance companies, stock brokerages, investment funds and some government sponsored enterprises.

As of 2004, the financial services industry represented 20% of the market capitalization of the S&P 500 in the United States. The U.S. finance industry comprised only 10% of total non-farm business profits in 1947, but it grew to 50% by 2010. Over the same period, finance industry income as a proportion of GDP rose from 2.5% to 7.5%, and the finance industry's proportion of all corporate income rose from 10% to 20%.
