“The 12 Federal Reserve banks provide the financial means to operate the Federal Reserve System. Each reserve bank is organized much like a private corporation so that it can provide the necessary revenue to cover operational expenses and implement the demands of the board. Member banks are privately owned banks that must buy a certain amount of stock in the Reserve Bank within its region to be a member of the Federal Reserve System. This stock “may not be sold, traded, or pledged as security for a loan” and all member banks receive a 6% annual dividend.[41] No stock in any Federal Reserve Bank has ever been sold to the public, to foreigners, or to any non-bank U.S. firm.” Source: Wikipedia
