The First Bank of the United States, chartered in 1791 under Alexander Hamilton's financial vision, was created to establish a stable national currency, handle federal government funds, provide a secure depository for tax revenues, and extend commercial credit to foster trade and manufacturing. By acting as a central fiscal agent, the institution sought to unify the chaotic post-revolutionary monetary system, manage national debt, and regulate the lending practices of early state-chartered banks to ensure overall economic stability across the newly formed republic.
