What is the importance of finance companies?

The flow of finance starts on Wall Street with the creation of capital used to fund business through the issuance of common stock to provide capital, bonds to lend capital and derivatives (packaged groups of securities that help to hedge against financial risk and replace the money banks lend out to borrowers). Public companies and municipalities use this capital to help fund their operations, and banks use it to lend to companies, municipalities and individuals to finance the purchase of goods and services.
