The document summarizes the key events of the US subprime mortgage crisis. It describes how home loans were made to borrowers with poor credit histories and uncertain employment who agreed to pay higher interest rates. When housing prices dropped in 2006 and interest rates rose, many of these subprime borrowers defaulted on their mortgages, leading to foreclosures. To stabilize the banking system, the US government implemented a $700 billion bailout program. The crisis had global economic impacts, including tighter credit, decreased lending, and slowed growth worldwide.
