Financial services refer to services provided by the finance industry, such as banking, insurance, investment funds, and more. There are two main types of financial services - fund or asset based services, which involve raising and investing funds, and fee based services, where companies earn income through fees. Fund based services include leasing, housing finance, credit cards, venture capital, factoring, forfeiting, and bill discounting. Fee based services involve activities like issue management, corporate advisory, credit ratings, mutual funds, and stock broking.
