Financial services refer to products offered by financial institutions like banks, insurance companies, and mutual funds. These include loans, credit cards, investments, and stock trading. Financial services have key characteristics of intermediating funds, intangibility, and perishability. Main functions include facilitating transactions, mobilizing savings, allocating capital, and meeting financial needs. There are various types of financial services based on consumers (individual or business), fund utilization (lending or non-lending activities), geography, and other features. Mutual funds are a form of financial service that pools investor money to invest in securities under different schemes.
