Banks play a significant role in the US economy. Wealth created by banks strengthens national purchasing power, resulting in a more stable economy. The banking sector pays billions of dollars in taxes every year. It also plays an important role in the economy as an employer – in 2013 the 20 largest banks in the USA employed over 1.2 million people, 228,000 of them at JP Morgan Chase Co.

Role of banks in the economy
Banks also play an important role as intermediaries in our everyday lives. In general, banks have three main functions: they are a place where people can safely invest their savings and earn interest; Banks provide loans to individuals and companies, and banks are responsible for the electronic payment system. Banks also do various other things, such as helping companies access capital and assisting with mergers and acquisitions. In general, banks are the intermediaries between those who want to invest their money and those who have ideas about how to use it.
