Which 2008 market crash was triggered by the collapse of the U.S. housing bubble and Lehman Brothers?

The 2008 market crash triggered by the U.S. housing bubble and Lehman Brothers’ collapse was the global financial crisis.

U.S. house prices rose for years while lenders issued many risky mortgages. These loans were bundled into securities and distributed through the financial system. When borrowers began defaulting and house prices fell, the value of mortgage-related assets became uncertain.

Lehman Brothers filed for bankruptcy on September 15, 2008, intensifying a worldwide loss of confidence. Credit markets froze, stock markets plunged, and governments supported banks and other institutions. The crisis produced a deep recession and major unemployment in many countries.

The event is also called the 2008 financial crisis or the global financial crisis. The housing bubble was an important cause, but the final collapse involved leverage, securitization, weak risk controls, and interconnected financial institutions.
