The bankruptcy of Lehman Brothers, also known as the Crash of '08 and the Lehman Shock on September 15, 2008, was the climax of the subprime mortgage crisis. After the financial services firm was notified of a pending credit downgrade due to its heavy position in subprime mortgages, the Federal Reserve summoned several banks to negotiate financing for its reorganization. These discussions failed, and Lehman filed a Chapter 11 petition that remains the largest bankruptcy filing in U.S. history, involving more than US$600 billion in assets.
The bankruptcy triggered a 4.5% one-day drop in the Dow Jones Industrial Average, then the largest decline since the attacks of September 11, 2001. It signaled a limit to the government's ability to manage the crisis and prompted a general financial panic. Money market mutual funds, a key source of credit, saw mass withdrawal demands to avoid losses, and the interbank lending market tightened, threatening banks with imminent failure. The government and the Federal Reserve system responded with several emergency measures to contain the panic.
As of May 2022, parent company Lehman Brothers Holdings, Inc. remained in liquidation before the Bankruptcy Court for the Southern District of New York. Caretaker offices in the US and abroad have continued to oversee payments to the company's creditors.[1]
