The 2007-2008 global financial crisis resulted from the collapse of the US housing bubble and loose lending practices, especially subprime mortgages. Housing prices rose sharply in the early 2000s due to low interest rates and high demand. When borrowers began defaulting in large numbers in 2006-2007 due to adjustable rate mortgages, banks and financial institutions that were invested in mortgage-backed securities suffered huge losses. This led to a liquidity crisis and credit crunch. The crisis had severe economic impacts, including stock market declines, high unemployment, and recession in the US and Europe.
