As of 2004 the financial services industry (finance 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%. The mean earnings per employee hour in finance relative to all other sectors has closely mirrored the share of total U.S. income earned by the top 1% income earners since 1930. The mean salary in New York City's finance industry rose from $80,000 in 1981 to $360,000 in 2011, while average New York City salaries rose from $40,000 to $70,000. In 1988, there were about 12,500 U.S. banks with less than $300 million in deposits, and about 900 with more deposits, but by 2012, there were only 4,200 banks with less than $300 million in deposits in the U.S., and over 1,801 with more.
The financial services industry constitutes the largest group of companies in the world in terms of earnings and equity market capitalization. However it is not the largest category in terms of revenue or number of employees. It is also a slow growing and extremely fragmented industry, with the largest company (Citigroup), only having a 3% US market share. In contrast, the largest home improvement store in the US, Home Depot, has a 30% market share, and the largest coffee house Starbucks has a market share of 32%.
Financial services are the economic services provided by the finance industry, which encompasses a broad range of businesses that manage money, including credit unions, banks, credit-card companies, insurance companies, accountancy companies, consumer-finance companies, stock brokerages, investment funds and some government-sponsored enterprises.
The term "financial services" became more prevalent in the United States partly as a result of the Gramm-Leach-Bliley Act of the late 1990s, which enabled different types of companies operating in the U.S. financial services industry at that time to merge.
Companies usually have two distinct approaches to this new type of business. One approach would be a bank which simply buys an insurance company or an investment bank, keeps the original brands of the acquired firm, and adds the acquisition to its holding company simply to diversify its earnings. Outside the U.S. (e.g., in Japan), non-financial services companies are permitted within the holding company. In this scenario, each company still looks independent, and has its own customers, etc. In the other style, a bank would simply create its own brokerage division or insurance division and attempt to sell those products to its own existing customers, with incentives for combining all things with one company.
