Banks in the economy

Size of global banking industry

Worldwide assets of the largest 1,000 banks grew 16.3% in 2006/2007 to reach a record $74.2 trillion. This follows a 5.4% increase in the previous year. EU banks held the largest share, 53%, up from 43% a decade earlier. The growth in Europe’s share was mostly at the expense of Japanese banks, whose share more than halved during this period from 21% to 10%. The share of US banks remained relatively stable at around 14%. Most of the remainder was from other Asian and European countries.^[8]

The United States has the most banks in the world in terms of institutions (7,540 at the end of 2005) and possibly branches (75,000).^{[citation needed]} This is an indicator of the geography and regulatory structure of the USA, resulting in a large number of small to medium-sized institutions in its banking system. As of Nov 2009, China's top 4 banks have in excess of 67,000 branches (ICBC:18000+, BOC:12000+,CCB:13000+,ABC:24000+) with an additional 140 smaller banks with an undetermined number of branches. Japan had 129 banks and 12,000 branches. In 2004, Germany, France, and Italy each had more than 30,000 branches—more than double the 15,000 branches in the UK.^[8]

[edit] Bank crisis

Banks are susceptible to many forms of risk which have triggered occasional systemic crises. These include liquidity risk (where many depositors may request withdrawals beyond available funds), credit risk (the chance that those who owe money to the bank will not repay it), and interest rate risk (the possibility that the bank will become unprofitable, if rising interest rates force it to pay relatively more on its deposits than it receives on its loans).

Banking crises have developed many times throughout history, when one or more risks have materialized for a banking sector as a whole. Prominent examples include the bank run that occurred during the Great Depression, the U.S. Savings and Loan crisis in the 1980s and early 1990s, the Japanese banking crisis during the 1990s, and the subprime mortgage crisis in the 2000s. Usually, the governments bail out the bank through rescue plan or individual public intervention.^[9]
