The global financial crisis of 2008 was caused by a number of interrelated factors: - Housing prices in the US increased dramatically from 2000-2005 before leveling off and declining, leaving many homeowners underwater on their mortgages. - Low interest rates set by the Federal Reserve from 2002-2006 contributed to the housing bubble and eventual collapse of major banks. - Banks were found to have manipulated the Libor interbank lending rate, falsely inflating their creditworthiness and profiting from trades, leading to billions in fines for banks like Barclays, RBS, HSBC, and Bank of America.
