When discussing the biggest companies, it is important to evaluate their assets. Some established public and private companies earn modest sums of money and some generate lots of profit, being able to sustain and support their functioning for long time periods. Such companies sooner or later become financial giants ready to make their influence not only on people involved in their formation, but also on whole nations and countries worldwide.

This is especially true for financial institutions such as commercial banks, investment banks, insurance companies, brokerages, investment companies, savings and loan associations and credit unions. The roles of the mentioned institutions may differ, depending on the purposes for which their services are used. For example, some are suitable for making investments such as term deposits, some are used for signing up for credit cards or getting loans etc. However, because they exist as parts of a wider financial system – on a global scale their international influence and rank may be very high, having a larger purpose in the overall world's economy.
