The U.S. subprime mortgage crisis was a set of events and conditions that led to a financial crisis and subsequent recession that began in 2007. It was characterized by a rise in subprime mortgage delinquencies and foreclosures, and the resulting decline of securities backed by said mortgages. Several major financial institutions collapsed in September 2008, with significant disruption in the flow of credit to businesses and consumers and the onset of a severe global recession.
