The government agency that controls it all!
The Fed is the government agency that controls a huge part of your life: the economy. The Fed's job is to stabilize the economy, along with other responsibilities. Regulate nation's money supply, supervise banks, supply currency, and oversee the development and function of the payment system are all jobs that the agency needs to do. The Fed separated parts of the country into 'district banks' that have a major city's bank supply that region's money supply. For example, the Chicago, Illinois bank takes care of the region it's located in.
