September 17, 2001: New York Stock Exchange Reopens; Economic Costs of Attack Are High

The New York Stock Exchange, closed since the 9/11 attacks, reopens. During the next five days, the Dow Jones drops nearly 2000 points, but then soon rebounds to above pre-9/11 levels. The attacks caused more than $20 billion in property damage to buildings in New York City and Washington. According to one estimate, the work stoppage and other loss of economic output costs about another $47 billion, making the attacks the costliest man-made disaster in US history. [ABC News, 9/10/2002]
