This document discusses the global financial crisis that began in 2007. It describes how the crisis was triggered by a liquidity shortfall in the US banking system that resulted in collapsed financial institutions. The crisis contributed to business failures, declines in wealth, government financial commitments, and reduced economic activity worldwide. Housing markets also suffered with increased foreclosures. The crisis is considered the worst since the Great Depression. Multiple causes have been proposed and governments have implemented regulatory and monetary policies to stimulate economies and stabilize financial markets.
