The Second Bank of the United States was the second federally authorized Hamiltonian national bank in the United States. Located in Philadelphia, Pennsylvania, the bank was chartered from February 1816 to January 1836. The bank's formal name, according to section 9 of its charter as passed by Congress, was "The President, Directors, and Company, of the Bank of the United States". While other banks in the US were chartered by and only allowed to have branches in a single state, it was authorized to have branches in multiple states and lend money to the US government.
A private corporation with public duties, the bank handled all fiscal transactions for the U.S. government, and was accountable to Congress and the U.S. Treasury. Twenty percent of its capital was owned by the federal government, the bank's single largest stockholder. Four thousand private investors held 80 percent of the bank's capital, including three thousand Europeans. The bulk of the stocks were held by a few hundred wealthy Americans. In its time, the institution was the largest monied corporation in the world.
