The Asian financial crisis was a period of financial crisis that gripped much of East Asia beginning in July 1997 and raised fears of a worldwide economic meltdown due to financial contagion.

The crisis started in Thailand (well known in Thailand as the Tom Yum Goong crisis; Thai: วิกฤตต้มยำกุ้ง) with the financial collapse of the Thai baht after the Thai government was forced to float the baht due to lack of foreign currency to support its currency peg to the U.S. dollar. At the time, Thailand had acquired a burden of foreign debt that made the country effectively bankrupt even before the collapse of its currency. As the crisis spread, most of Southeast Asia and Japan saw slumping currencies, devalued stock markets and other asset prices, and a precipitous rise in private debt.

Indonesia, South Korea and Thailand were the countries most affected by the crisis. Hong Kong, Laos, Malaysia and the Philippines were also hurt by the slump. Brunei, China, Singapore, Taiwan and Vietnam were less affected, although all suffered from a loss of demand and confidence throughout the region.

The term financial crisis is applied broadly to a variety of situations in which some financial assets suddenly lose a large part of their nominal value. In the 19th and early 20th centuries, many financial crises were associated with banking panics, and many recessions coincided with these panics. Other situations that are often called financial crises include stock market crashes and the bursting of other financial bubbles, currency crises, and sovereign defaults. Financial crises directly result in a loss of paper wealth but do not necessarily result in changes in the real economy.

Many economists have offered theories about how financial crises develop and how they could be prevented. There is no consensus, however, and financial crises continue to occur from time to time.

Types

Banking crisis

When a bank suffers a sudden rush of withdrawals by depositors, this is called a bank run. Since banks lend out most of the cash they receive in deposits (see fractional-reserve banking), it is difficult for them to quickly pay back all deposits if these are suddenly demanded, so a run renders the bank insolvent, causing customers to lose their deposits, to the extent that they are not covered by deposit insurance. An event in which bank runs are widespread is called a systemic banking crisis or banking panic.

The financial crisis of 2007–08, also known as the global financial crisis and 2008 financial crisis, is considered by many economists to have been the worst financial crisis since the Great Depression of the 1930s. It threatened the collapse of large financial institutions, which was prevented by the bailout of banks by national governments, but stock markets still dropped worldwide. In many areas, the housing market also suffered, resulting in evictions, foreclosures and prolonged unemployment. The crisis played a significant role in the failure of key businesses, declines in consumer wealth estimated in trillions of U.S. dollars, and a downturn in economic activity leading to the 2008–2012 global recession and contributing to the European sovereign-debt crisis. The active phase of the crisis, which manifested as a liquidity crisis, can be dated from August 9, 2007, when BNP Paribas terminated withdrawals from three hedge funds citing "a complete evaporation of liquidity".

The Panic of 1873 was a financial crisis that triggered a depression in Europe and North America that lasted from 1873 until 1879, and even longer in some countries. In Britain, for example, it started two decades of stagnation known as the "Long Depression" that weakened the country's economic leadership. The Panic was known as the "Great Depression" until the events in the early 1930s took precedence.

The Panic of 1873 and the subsequent depression had several underlying causes, of which economic historians debate the relative importance. Post civil war inflation, rampant speculative investments (overwhelmingly in railroads), a large trade deficit, ripples from economic dislocation in Europe resulting from the Franco-Prussian War (1870-1871), property losses in the Chicago (1871) and Boston (1872) fires, and other factors put a massive strain on bank reserves, which plummeted in New York City during September and October 1873 from $50 million to $17 million.

The first symptoms of the crisis were financial failures in the Austro-Hungarian capital, Vienna, which spread to most of Europe and North America by 1873.
