Which 2008 stock-market crisis prompted the U.S. government’s $700 billion Troubled Asset Relief Program?

The 2008 stock-market crisis that prompted the U.S. government’s $700 billion Troubled Asset Relief Program was the global financial crisis.

Congress authorized the Troubled Asset Relief Program, commonly called TARP, in October 2008 through the Emergency Economic Stabilization Act. Its original purpose was to purchase or insure troubled mortgage-related assets, although the program was also used to inject capital into banks and support parts of the U.S. financial system.

The crisis had roots in the U.S. housing boom, risky mortgage lending, complex securitized debt, and excessive financial leverage. When housing prices fell and mortgage defaults rose, losses spread through banks and global markets. The failure of Lehman Brothers in September 2008 intensified the panic.

TARP was only one part of the response. Central banks cut interest rates, provided emergency liquidity, and introduced other extraordinary measures. The program became politically contentious, but many of its investments were later repaid with returns to the U.S. Treasury.
