The 2007–2008 financial crisis, or Global Financial Crisis (GFC), was the most severe worldwide economic crisis since the Great Depression of 1929. Predatory lending targeting low-income homebuyers, excessive risk-taking by global financial institutions, and the bursting of the United States housing bubble culminated in a "perfect storm".

Mortgage-backed securities (MBS) tied to American real estate, as well as a vast web of derivatives linked to those MBS, collapsed in value. Financial institutions worldwide suffered severe damage, reaching a climax with the bankruptcy of Lehman Brothers on September 15, 2008, and a subsequent international banking crisis.

2007–2008 financial crisis

The preconditioning for the financial crisis was complex and multi-causal. Almost two decades prior, the U.S. Congress had passed legislation encouraging financing for affordable housing. However, in 1999, parts of the Glass-Steagall legislation, which had been adopted in 1933, were repealed, permitting financial institutions to commingle their commercial (risk-averse) and proprietary trading (risk-taking) operations. Arguably the largest contributor to the conditions necessary for financial collapse was the rapid development in predatory financial products which targeted low-income, low-information homebuyers who largely belonged to racial minorities. This market development went unattended by regulators and thus caught the U.S. government by surprise.

After the onset of the crisis, governments deployed massive bail-outs of financial institutions and other palliative monetary and fiscal policies to prevent a collapse of the global financial system. In the U.S., the October 3, $800 billion Emergency Economic Stabilization Act of 2008 failed to slow the economic free-fall, but the similarly-sized American Recovery and Reinvestment Act of 2009, which included a substantial payroll tax credit, saw economic indicators reverse and stabilize less than a month after its February 17 enactment. The crisis sparked the Great Recession which resulted in increases in unemployment and suicide, and decreases in institutional trust and fertility, among other metrics. The recession was a significant precondition for the European debt crisis.

In 2010, the Dodd–Frank Wall Street Reform and Consumer Protection Act was enacted in the US as a response to the crisis to "promote the financial stability of the United States". The Basel III capital and liquidity standards were also adopted by countries around the world.

Background

The crisis sparked the Great Recession, which, at the time, was the most severe global recession since the Great Depression. It was also followed by the European debt crisis, which began with a deficit in Greece in late 2009, and the 2008–2011 Icelandic financial crisis, which involved the bank failure of all three of the major banks in Iceland and, relative to the size of its economy, was the largest economic collapse suffered by any country in history. It was among the five worst financial crises the world had experienced and led to a loss of more than $2 trillion from the global economy. U.S. home mortgage debt relative to GDP increased from an average of 46% during the 1990s to 73% during 2008, reaching $10.5 (~$ in ) trillion. The increase in cash out refinancings, as home values rose, fueled an increase in consumption that could no longer be sustained when home prices declined. Many financial institutions owned investments whose value was based on home mortgages such as mortgage-backed securities, or credit derivatives used to insure them against failure, which declined in value significantly. The International Monetary Fund estimated that large U.S. and European banks lost more than $1 trillion on toxic assets and from bad loans from January 2007 to September 2009.
