The amount of stock a member bank must own is equal to 3% of its combined capital and surplus. However, holding stock in a Federal Reserve bank is not like owning stock in a publicly traded company. These stocks cannot be sold or traded, and member banks do not control the Federal Reserve Bank as a result of owning this stock. From their Regional Bank, member banks with $10 billion or less in assets receive a dividend of 6%, while member banks with more than $10 billion in assets receive the lesser of 6% or the current 10-year Treasury auction rate. The remainder of the regional Federal Reserve Banks' profits is given over to the United States Treasury Department. In 2015, the Federal Reserve Banks made a profit of $100.2 billion and distributed $2.5 billion in dividends to member banks as well as returning $97.7 billion to the U.S. Treasury.
