Institution that deals in money and its substitutes and provides other financial services. Banks accept deposits and make loans and derive a profit from the difference in the interest paid to lenders (depositors) and charged to borrowers, respectively. They also profit from fees charged for services. The three major classes of banks are commercial banks, investment banks, and central banks. Banking depends entirely on public confidence in the system's soundness; no bank could pay all its depositors should they simultaneously demand cash, as may happen in a panic. See also credit union; Federal Reserve System; savings and loan association; savings bank.
