The
United States (U.S.)
subprime mortgage crisis was a nationwide banking emergency that coincided with the U.S. recession of December 2007 – June 2009. It was triggered by a large decline in home prices after the collapse of a
housing bubble, leading to mortgage delinquencies and foreclosures and the devaluation of housing-related securities. Declines in residential investment preceded the recession and were followed by reductions in household spending and then business investment. Spending reductions were more significant in areas with a combination of high household debt and larger housing price declines.
