A bank is a financial institution that accepts deposits from the public and creates a demand deposit while making loans. Lending activities can be directly performed by the bank or indirectly through capital markets.
American Union Bank, New York City, April 26, 1932
A bank run or run on the bank occurs when many clients withdraw their money from a bank, because they believe the bank may fail in the near future. It may occur when, in a fractional-reserve banking system (where banks normally only keep a small proportion of their assets as cash), a large volume of customers seek to withdraw a greater amount of cash from deposit accounts with a financial institution in a short space of time than the institution has cash on-hand, because the customers believe that the institution is, or might become, insolvent. When they transfer funds to another institution, it may be characterized as a capital flight. As a bank run progresses, it may become a self-fulfilling prophecy: as more people withdraw cash, the likelihood of default increases, triggering further withdrawals. This can destabilize the bank to the point where it runs out of cash and thus faces sudden bankruptcy. To combat a bank run, a bank may acquire more cash from other banks or from the central bank, or limit the amount of cash customers may withdraw, either by imposing a hard limit or by scheduling quick deliveries of cash, encouraging high-return term deposits to reduce on-demand withdrawals or suspending withdrawals altogether.
A banking panic or bank panic is a financial crisis that occurs when many banks suffer runs at the same time, as people suddenly try to convert their threatened deposits into cash or try to get out of their domestic banking system altogether. A systemic banking crisis is one where all or almost all of the banking capital in a country is wiped out. The resulting chain of bankruptcies can cause a long economic recession as domestic businesses and consumers are starved of capital as the domestic banking system shuts down. According to former U.S. Federal Reserve chairman Ben Bernanke, the Great Depression was caused by the failure of the Federal Reserve System to prevent deflation, and much of the economic damage was caused directly by bank runs. The cost of cleaning up a systemic banking crisis can be huge, with fiscal costs averaging 13% of GDP and economic output losses averaging 20% of GDP for important crises from 1970 to 2007.

An old Nixdorf ATM in Germany (German: Bankautomat) An automated teller machine (ATM) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance or account information inquiries, at any time and without the need for direct interaction with bank staff.
ATMs are known by a variety of other names, including automatic teller machines (ATMs) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term automated banking machine (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM rather than ABM. In British English, the terms cashpoint, cash machine and hole in the wall are also used. ATMs that are not operated by a financial institution are known as "white-label" ATMs. (Full article...)

The Gramm–Leach–Bliley Act (GLBA), also known as the Financial Services Modernization Act of 1999, (Pub. L.106–102 (text)(PDF), 113 Stat.1338, enacted November 12, 1999) is an Act of the 106th United States Congress (1999–2001). It repealed part of the Glass–Steagall Act of 1933, removing barriers in the market among banking companies, securities companies, and insurance companies that prohibited any one institution from acting as any combination of an investment bank, a commercial bank, and an insurance company. With the passage of the Gramm–Leach–Bliley Act, commercial banks, investment banks, securities firms, and insurance companies were allowed to consolidate. Furthermore, it failed to give to the SEC or any other financial regulatory agency the authority to regulate large investment bank holding companies. The legislation was signed into law by President Bill Clinton.
A year before the law was passed, Citicorp, a commercial bank holding company, merged with the insurance company Travelers Group in 1998 to form the conglomerate Citigroup, a corporation combining banking, securities and insurance services under a house of brands that included Citibank, Smith Barney, Primerica, and Travelers. Because this merger was a violation of the Glass–Steagall Act and the Bank Holding Company Act of 1956, the Federal Reserve gave Citigroup a temporary waiver in September 1998. Less than a year later, GLBA was passed to legalize these types of mergers on a permanent basis. The law also repealed Glass–Steagall's conflict of interest prohibitions "against simultaneous service by any officer, director, or employee of a securities firm as an officer, director, or employee of any member bank".

World map showing real GDP growth rates for 2009; countries in brown were in a recession.
The Great Recession was a period of market decline in economies around the world (particularly in the western world and associated countries) that occurred from late 2007 to mid-2009, overlapping with the closely related 2008 financial crisis. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression of the 1930s.
The Great Recession was caused by many weaknesses that slowly developed in the global financial system, along with a series of triggering events that began with the bursting of the United States housing bubble in 2005–2012. When housing prices fell and homeowners began to abandon their mortgages, the value of mortgage-backed securities held by investment banks declined in 2007–2008, causing several banks to collapse or be bailed out in September 2008. This 2007–2008 phase became known as the subprime mortgage crisis. (Full article...)

UML class diagram depicting a customer with accounts A transaction account (also called a checking account, cheque account, chequing account, current account, demand deposit account, or share account at credit unions) is a deposit account or bank account held at a bank or other financial institution. It is available to the account owner "on demand" and is available for frequent and immediate access by the account owner or to others as the account owner may direct. Access may be in a variety of ways, such as cash withdrawals, use of debit cards, cheques and electronic transfer. In economic terms, the funds held in a transaction account are regarded as liquid funds. In accounting terms, they are considered as cash.
Transaction accounts are known by a variety of descriptions, including a current account (British English), chequing account or checking account when held by a bank, share draft account when held by a credit union in North America. In the Commonwealth of Nations, United Kingdom, Hong Kong, India, Ireland, Australia, New Zealand, Singapore, Malaysia, South Africa and a number of other countries they are commonly called current or, before the demise of cheques, cheque accounts. Because money is available on demand they are also sometimes known as demand accounts or demand deposit accounts. In the United States, NOW accounts operate as transaction accounts. (Full article...)

A savings bank is a financial institution that is not run on a profit-maximizing basis, and whose original or primary purpose is collecting deposits on savings accounts that are invested on a low-risk basis and receive interest. Savings banks have mostly existed as a separate category in Europe.
Savings banks originated in late-18th century Europe as a development of the Enlightenment, and became a Europe-wide phenomenon in the first half of the 19th century. The trajectories of savings bank systems then diverged across European nations, variously leading to the formation of integrated banking groups, cohesive national networks, conversion into cooperative banking or commercial banking entities, and/or piecemeal consolidation with other credit institutions. In most countries, the surviving savings banks have private-sector status and no longer operate under a distinctive legislative framework; significant exceptions include Germany and Luxembourg, where savings banks are public-sector entities.
