What 2008 crash is represented by the collapse of Lehman Brothers on September 15?

The 2008 crash represented by Lehman Brothers’ collapse on September 15 was the global financial crisis.

Lehman Brothers filed for bankruptcy on September 15, 2008, after losses connected to mortgage-related assets and declining real-estate markets. Its failure intensified panic in credit and stock markets because Lehman was a large, internationally connected investment bank.

The crisis had begun earlier with problems in U.S. housing finance and credit markets. It spread through banks, insurers, businesses, and households around the world. Governments and central banks used emergency lending, guarantees, bailouts, and very low interest rates to contain the damage. Lehman’s bankruptcy is a landmark date, but it was one event within a crisis that developed over several years and continued after 2008.
